    Filed March 6, 2020
    STATE OF IOWA,
    Appellee,
    vs.
    JARROD DALE MAJORS,
    Appellant.
    Appeal from the Iowa District Court for Taylor County, John D.
    Lloyd, Judge.
    Defendant appeals from a second resentencing order imposing a
    mandatory minimum sentence for attempted murder committed as a
    juvenile. AFFIRMED.
    Bradley Bender, Assistant Appellate Defender, for appellant.
    Thomas J. Miller, Attorney General, Louis S. Sloven, Assistant
    Attorney General, and Clinton L. Spurrier, County Attorney, for appellee.

    WATERMAN, Justice.
    In this appeal, we must decide whether the district court abused its
    discretion by imposing a seventeen and one-half-year mandatory
    minimum prison term before parole eligibility on the defendant’s second
    resentencing for attempted murder during a home invasion and whether
    defense counsel provided constitutionally deficient representation. The
    defendant was age seventeen at the time of the crime in 2002, and he has
    been resentenced twice as our caselaw on juvenile sentencing evolved. See
    State v. Majors, 
    897 N.W.2d 124
    , 127 (Iowa 2017) (remanding for
    resentencing in light of State v. Roby, 
    897 N.W.2d 127
    (Iowa 2017)
    (plurality opinion), decided the same day). The defendant, now age thirty-
    five, appeals his latest resentencing, contending that the district court
    failed to follow our court’s 2017 mandate to apply Roby and that his
    counsel was ineffective for failing to present a defense expert on the youth
    sentencing factors. We retained the appeal.
    On our review, we determine the district court did not abuse its
    discretion by imposing the mandatory minimum after considering the
    youth sentencing factors under Roby.       The sentence is supported by
    testimony from the State’s expert. The defendant personally chose not to
    retain a defense expert, and we conclude his counsel was not
    constitutionally ineffective for relying on cross-examination of the State’s
    expert without retaining a defense expert that his client chose to forgo.
    Accordingly, we affirm the district court’s judgment of sentence.
    I. Background Facts and Proceedings.
    On May 30, 2002, Jarrod Dale Majors was a seventeen-year-old high
    school senior fifteen days away from his eighteenth birthday. He lived with
    his parents on a quiet street in Bedford, Iowa.       Majors had become
    obsessed with Hollie Peckham, a thirty-year-old woman who lived across
    3
    the street with her thirty-two-year-old husband, Jamie Peckham, and their
    twenty-two-month-old twins. While the Peckhams were away one evening,
    Majors entered their home, hid inside the closet of the master bedroom,
    and awaited their return. Majors wore a ski mask and gloves to avoid
    identification. He attached a large knife to his waistband, wrapped a roll
    of duct tape around his wrist, and held a .22 caliber rifle with a plastic
    soda bottle taped to the barrel to act as a makeshift silencer.
    When the Peckhams returned home, Hollie went upstairs while
    Jamie remained downstairs with the twins. As Hollie entered her bedroom,
    Majors emerged from the closet and attacked while pointing the gun at
    her. Hollie screamed for her husband, and Majors told her that he was
    not there, which led Hollie to believe Majors had killed him. She ran out
    of the bedroom, down the stairs, and out of the house screaming for help.
    Hollie found a neighbor, who accompanied her back to the Peckham home
    while his wife called the police. Meanwhile, Jamie subdued Majors after a
    struggle witnessed by the toddlers. The neighbor helped Jamie restrain
    Majors until the police arrived. Jamie later testified that he knew who the
    assailant was before removing his ski mask because he had repeatedly
    seen Majors trespassing and peering in bathroom windows at Hollie over
    the preceding two years. Hollie injured her ankle during the incident, and
    the entire family was emotionally traumatized. Jamie described it at the
    most recent resentencing hearing as “[k]ind of feel[ing] like there’s a 9-11
    that happened where we survived, but it changed everything.           It’s a
    watershed moment.”
    Majors initially told the police that he was paid $100 to commit the
    crime as a prank.     His story later changed to claiming he had been
    hallucinating and could not remember the crime due to using drugs and
    prolonged sleep deprivation. As motive for his crime, he claimed to believe
    4
    that Jamie was going to attack him and poison his dog. Majors had no
    prior criminal record apart from a single offense for possession of alcohol
    as a minor.
    Majors pled guilty to attempted murder in exchange for the State’s
    agreement to dismiss the remaining ten charges upon the expiration of the
    appeal deadline and on the condition that there would be no appeal.
    Majors was sentenced on January 22, 2003, to a prison term of up to
    twenty-five years with a mandatory minimum of seventeen and one-half
    years before parole eligibility. Majors appealed the sentence in violation of
    the plea agreement, prompting the county attorney to refile the dismissed
    counts.   On May 13, Majors entered into a second plea agreement by
    pleading guilty to burglary in the second degree. He was sentenced to a
    ten-year term for that charge, which was to be served consecutively to his
    sentence for attempted murder. In exchange, the State agreed to amend
    the charge of burglary from first to second degree and to dismiss the
    remaining charges after the appeal deadline as long as Majors did not
    appeal. Majors did not file a direct appeal from his sentence.
    In 2014, we decided State v. Lyle, holding that any automatic
    mandatory minimum sentences of imprisonment for youthful offenders
    violated the Iowa Constitution’s provision against cruel and unusual
    punishment.    
    854 N.W.2d 378
    , 404 (Iowa 2014).          Majors filed for a
    resentencing hearing based on Lyle. On September 16 of that year, when
    Majors was thirty years old, the district court conducted a resentencing
    hearing applying the Lyle factors.
    Majors was resentenced to a term of incarceration of up to twenty-
    five years for attempted murder with a mandatory minimum of seventeen
    and one-half-years before parole eligibility. His ten-year sentence on the
    burglary conviction remained in place with the sentences to be served
    5
    consecutively. Majors appealed, and the court of appeals affirmed the
    sentence after determining the district court had properly considered the
    Lyle factors.   On further review, we determined that the district court
    abused its discretion by imposing a minimum period of incarceration
    without eligibility for parole under Roby, decided the same day. 
    Majors, 897 N.W.2d at 127
    . We reversed Majors’ sentence and remanded for a
    second resentencing consistent with the Lyle factors as explained in Roby,
    which stated that “the factors must not normally be used to impose a
    minimum sentence of incarceration without parole unless expert evidence
    supports the use of the factors to reach such a 
    result.” 897 N.W.2d at 147
    .
    At the second resentencing hearing on March 5, 2018, when Majors
    was age thirty-three, defense counsel told the court his client chose not to
    retain an expert, and the court conducted a colloquy to confirm this was
    Majors’ own decision:
    MR. BOOTH: . . . I’ve had discussions with Mr. Majors
    in regard to whether or not we should have requested or tried
    to obtain an independent psychiatric evaluation since we
    knew the State was intending to call a psychiatrist to testify
    and to subject the defendant to a psychiatric evaluation on
    behalf of the State.
    In my discussions with Mr. Majors, it’s my
    understanding that he does not wish to delay these
    proceedings any longer, that he is comfortable proceeding
    without the assistance of an independent psychiatric
    evaluation, Your Honor. . . .
    [the Court swore in Majors]
    ....
    MR. BOOTH: I’ve also advised you that we could ask the
    court for State funds in order to hire a psychiatrist or conduct
    an independent psychiatric evaluation to support your
    position at sentencing. Are you aware of that?
    THE DEFENDANT: Yes.
    MR. BOOTH: And was it your decision that we not hire
    an independent or obtain an independent evaluation?
    6
    THE DEFENDANT: Yes.
    MR. BOOTH: Was that because your belief is that we
    should proceed -- your desire is to not have any further delays
    and proceed with resentencing; is that correct?
    THE DEFENDANT: That’s correct.
    MR. BOOTH: Thank you, Your Honor.
    THE COURT: Mr. Majors, without telling me what [you
    and] Mr. Booth discussed, do you feel you’ve had enough time
    to discuss this issue with him, or would you like some more
    time to discuss it with him?
    THE DEFENDANT: I believe I’ve had enough time.
    THE COURT: Is it your decision that you not ask for any
    further continuances?
    THE DEFENDANT: Yes, my decision.
    The court additionally offered to leave the record open to give Majors an
    opportunity to submit additional evidence later, but Majors declined the
    offer.
    The hearing proceeded with live testimony from two witnesses:
    Deputy Nate Bucher and Dr. Theresa Clemmons, a psychiatrist at the
    department of corrections serving as the State’s expert. Jamie Peckham
    gave an oral victim-impact statement.
    Dr. Clemmons formed her opinions after reviewing Majors’ records
    and interviewing him by teleconference. Dr. Clemmons noted Majors’ prior
    inconsistent statements regarding his mindset during the crime, but she
    stated that “when we discussed what happened he was able to tell me
    specifically” what he did and that Majors admitted he did not do the crime
    on a dare. Dr. Clemmons testified that “[she did not] believe he’s taking
    full responsibility for the entirety of all of his actions the night of the
    offense.”      The prosecutor and defense counsel each questioned
    Dr. Clemmons extensively regarding her conclusions under the five
    sentencing factors. Those factors are
    (1) the age of the offender and the features of youthful
    behavior, such as “immaturity, impetuosity, and failure to
    7
    appreciate risks and consequences”; (2) the particular “family
    and home environment” that surround the youth; (3) the
    circumstances of the particular crime and all circumstances
    relating to youth that may have played a role in the
    commission of the crime; (4) the challenges for youthful
    offenders in navigating through the criminal process; and (5)
    the possibility of rehabilitation and the capacity for change.
    
    Lyle, 854 N.W.2d at 404
    n.10 (quoting Miller v. Alabama, 
    567 U.S. 460
    ,
    477–78, 
    132 S. Ct. 2455
    , 2468 (2012)); see also 
    Roby, 897 N.W.2d at 135
    (quoting same factors).
    The prosecutor began with the first factor.
    The first one is the youthful offender status or fact, that
    the person was in fact not 18 years old at the time of the
    commission of the crime.
    ....
    Q. In looking at that factor, how did you think that
    played into the defendant’s situation in this case? In other
    words, do you feel that his status in the case at the time this
    happened would mitigate his responsibility for what
    happened, substantially or minimally mitigate it? A. I would
    say more so minimally mitigate it. Looking at the overall
    youthful offender, the idea of a youthful offender is the idea of
    brain maturing and whether brains mature enough to make
    good decisions, whether you have good control of your
    emotions, good control [over] impulsivity, have good
    development of your frontal lobe specifically, and the idea of
    that is that over time your brain does develop, it matures.
    But looking at his age, from 17 years and 50 weeks to
    18 years is a very small change. It’s not a switch. It’s not on
    an 18th birthday you flip a switch and the brain is fully
    mature. It actually takes much longer than the 18th birthday
    to reach the full maturity, and some people say your brain is
    ever changing during your lifetime, and we have no mark for
    full brain maturity.
    So looking at kind of those ideas, there would have been
    minimal brain change or brain growth or brain development
    within those two weeks. So it wouldn’t have necessarily
    changed his ability to make decisions, his ability to control
    emotions better or worse, his ability to have impulse control,
    that sort of thing.
    ....
    Q. So in terms of mitigating his responsibility for the
    crime, at best [the first factor] would have minimal mitigating
    value; would that be fair? A. Yes.
    8
    On cross-examination, Dr. Clemmons stated that she was looking
    at this factor from the perspective of whether Majors was a risk to all
    parties involved and emphasized her focus on whether he displayed any
    empathy. Majors’ counsel asked whether she thought Majors may not
    have contemplated the risks and consequences to the victims, and she
    replied that she did not specifically ask him that so she could not answer.
    The prosecutor’s direct examination then elicited the expert’s
    testimony on the second factor, Majors’ supportive family and home
    environment.
    A. He described his family as supportive. He described his
    relationship with his mother as a good relationship. He and
    his mother still have frequent visits, and they talk regularly.
    He mentioned that his mother was supportive growing up. He
    denied any abuse.
    He did mention with his father the physical abuse that
    we talked about, but he did mention that through the years
    that he and his father did have a good, supportive relationship
    over the years, also came up for visits as well.
    And then him and his brother also have a good
    relationship, from my understanding. Growing up they had
    some similar friends. And they denied any abuse going back
    and forth. He mentioned they would have had, you know, the
    typical brother relationship where they probably roughhouse
    a bit and that but no abuse back and forth between the boys.
    Q. So the only negative he described to you in relation
    to his family relationship was a period of prior abuse by his
    father; is that correct? A. Yes.
    Q. And that would have ended when he would have
    been roughly in sixth grade; correct? A. Yes, he mentioned
    the physical abuse ended in sixth grade.
    Q. He described to you after that period of time he and
    his father developed a good relationship?           A. To my
    understanding, yes.
    Dr. Clemmons testified that Majors’ other familial relationships with his
    brother and mother had been good at the time of the crime and continue
    to be, that there were no substance abuse issues within the family or other
    9
    abuse, and that it would be fair to say that Majors basically described a
    positive, supportive family.
    Q. So again in terms of this factor, did you say anything
    about his home environment or relationship would mitigate
    his actions in terms of the crime? A. At the time of the
    offense, there didn’t appear to be anything going on within the
    family that would have mitigated anything.
    Q. The people that you deal with in the prison system,
    is it fairly common that many of them have very troubled home
    lives? A. Absolutely.
    Q. And that’s contributed to them being where they’re
    at; would that be fair to say? A. Absolutely.
    Q. And you didn’t see anything in this case; did you?
    A. Not at the time of offense.
    Q. Would it be fair to say that factor would have
    minimum mitigating value in this case? A. Yes.
    Majors’ counsel cross-examined Dr. Clemmons regarding how
    Majors’ childhood scoliosis, surgery in the sixth grade, and his inability to
    participate in sports affected his home environment. In response, she
    noted she was focusing on his home environment at the time of the crime
    many years later.
    The prosecutor then turned to the third factor, the circumstances of
    the crime, in which Dr. Clemmons noted the absence of peer pressure.
    Q. The next factor I wanted to look at is the
    circumstances of the crime and I think in terms of the Iowa
    Supreme Court looking at the issue of outside influences
    significantly. Did you look at that issue as well in relation to
    the defendant? A Yes.
    Q. And in terms of involvement of other youthful people
    with him, did you find any evidence of that in this particular
    case? A. No, I did not.
    Q. I believe the supreme court case indicated if they
    were jointly committing crimes with others. In this case is
    there any evidence whatsoever that anyone else participated
    with the defendant in the commission of this crime? A. No.
    Q. Is there any indication that anybody else was
    involved in the planning or preparation for this crime? A. No.
    10
    Q. In terms of those factors such as peer pressure, did
    he indicate to you any indication that peer pressure played a
    role in what he did that night? A. No.
    Dr. Clemmons went on to state that she would not classify Majors’ crime
    as an impulsive one, but rather it appeared to be planned given the
    clothing to mask his identity, the rifle with a makeshift silencer, and the
    knife as a backup weapon.
    Q. In terms of what we have here, we have one who had
    a well thought out crime and did so in a way that was going
    to minimize their likelihood of being caught and held
    accountable; would that be correct? A. That is correct.
    Q. Again in terms of the circumstances of the crime,
    would you say that the factors and circumstances would
    provide minimal mitigating value of the defendant’s youthful
    offender in this case? A. Correct.
    On cross-examination, defense counsel challenged Dr. Clemmons about
    impulsivity and her belief that this was a planned crime.
    When discussing the fourth factor, the defendant’s competency to
    navigate legal proceedings, Dr. Clemmons testified on direct that she had
    reviewed Majors’ competency evaluation from his forensic psychiatric
    hospitalization close in time to the crime.
    Q. And were you able to determine from that whether
    the defendant was competent to understand what he was
    doing in terms of being able to assist in his defense in the case
    that was pending against him? A. Yes. . . . In the letter from
    Dr. Hartman from August 2, 2002, Dr. Hartman mentions
    that Mr. Majors was competent to participate in judicial
    proceedings. He stated he currently does not have a mental
    condition which prevents him from appreciating his charge,
    understanding the proceedings or assisting in his own
    defense.
    I reviewed his history and available data surrounding
    the activities in question and would indicate that Mr. Majors
    understood the nature and quality of behavior in which he
    was allegedly involved. That statement and information would
    indicate at that time he had sufficient competency to
    distinguish right from wrong. It is equally this writer’s opinion
    that at this time he had capacity to form intent consistent with
    accountability.
    11
    Dr. Welch, who was also the psychologist who met with
    him, stated he does appear to be well aware of the charges
    against him and can aid in his own defense.
    So both a licensed psychologist and a psychiatrist
    mentioned that they thought he had no -- there was no
    concern for diminished capacity or competency at that time.
    Q. And that was based on an evaluation done in July
    of 2002; correct? A. Yes, that is correct.
    Q. Would you have expected that from May 25, 2002,
    when the evaluation was done, any reasonable likelihood
    there would have been a significant change in his mental
    capacity and competency during that small window of time?
    A. None of the information I have would have indicated that,
    no.
    Q. In this case would you say it’s also significant that
    to an extent the defendant kind of throughout the progress of
    this case kind of went through a checklist of more or less
    minimizing any responsibility?       First someone there, to
    offering me money, next thing I’ve got a mental competency
    issue, I don’t understand to the point of asking other prisoners
    how to make it sound more effective, to I’m not responsible
    because of use of drugs and a blackout? A. It seemed that he
    was definitely trying to find ways to reduce his responsibility
    for the actions that he had performed.
    Q. And doing ways recognized by the legal system;
    correct? A. Correct.
    Q. Diminished capacity would provide a potential legal
    defense; correct? A. Correct.
    Q. So      would     substance     abuse     intoxication?
    A. Correct.
    Q. Again I would ask you in this case do you feel that,
    based upon your information, that the defendant was fully
    able to understand the legal proceedings and navigate the
    legal system at that time? A. I don’t have any information to
    the contrary.
    Q. So again this would be another minimal mitigating
    value in terms of his being a youthful offender; correct?
    A. Yes.
    Defense counsel cross-examined Dr. Clemmons about Majors’ difficulty in
    school.
    In terms of going into the alternative school, it sounds
    like a smaller class size, more attention, and also he
    mentioned to me it was only three hours a day versus the full
    seven to eight hours of schooling, which was his preference.
    12
    Lastly, Dr. Clemmons addressed the fifth factor, capacity for
    rehabilitation, recognizing in this case that they had the benefit of sixteen
    years of hindsight since this 2002 crime, Majors’ prison disciplinary
    history, and his long-standing and continuing lack of empathy and
    remorse.
    Q. And in terms of his rehabilitative capacity, what
    would your thoughts be in that area? A. I have several
    thoughts in that area. He does have . . . the ability in terms
    of understanding what the treatment program would be like.
    His IQ is good, so he would be able to understand the content.
    He does not have any behavior problems right now. He
    hasn’t had disciplin[e] since 2014, so there wouldn’t be any
    problems with him sitting in class, going through treatment,
    performing those kind of things.
    The main point that I’ve been concerned about -- and I
    think this was also mentioned in the presentence
    investigation from 2002 but really gets him out of his
    evaluation -- was the concern for feelings of remorse, empathy
    for the victims and also feelings of guilt for his actions.
    That really comes down to the core of what the
    rehabilitation is in terms of taking responsibility for the
    action, admitting wrongdoing and then going through that
    treatment with kind of that desire to want to change so that
    way in the future whatever underlying factor led you to that
    offense doesn’t lead you to that offense in the future.
    Q. Or other offenses? A. Right.
    Q. In this case did you feel that the defendant showed
    remorse for what he had done? A. I didn’t get that sense, no.
    Q. We’ve already talked about the victim empathy and
    accepting responsibility issues. And so together with those
    three, in your opinion, do you think those things all will
    reduce the effectiveness of full rehabilitation in relation to the
    defendant? A. That would reduce the rehabilitation, correct.
    Q. If you’re looking at whether the prospect of him
    being a good candidate for parole rehabilitation, that would be
    something that, based upon the information you’ve looked at
    and reviewed, you would say he’s not a good prospect for full
    rehabilitation; would that be fair? A. I would say that’s
    correct.
    Q. Again in evaluating this factor, rehabilitation would
    be something that would be a minimal mitigating value in our
    analysis of assessment of what the appropriate sentence
    would be; would you say that’s fair? A. Yes.
    13
    On cross-examination, Dr. Clemmons acknowledged that Majors had
    shown a capacity for change since 2014 and that Majors apologized to the
    Peckhams at his previous sentencing hearings, but she noted his motive
    for secondary gain. Dr. Clemmons admitted to working primarily with
    adults and that Majors’ was her first resentencing hearing on the
    Miller/Lyle/Roby factors.
    The district court subsequently issued its resentencing order
    stating, “The court will consider the five factors as applied to this case, in
    light of the explication of those factors contained in Roby.”      The court
    outlined in considerable detail Roby’s description of each factor and its
    analysis of each factor’s application to Majors’ case.
    Regarding the first factor, age and maturity, the district court noted
    that Majors was fifteen days shy of his eighteenth birthday at the time of
    the crime, and found
    it [was] reasonable to assume that he would have been more
    mature than a 15 or 16 year old defendant and not
    appreciably less mature than if he had committed the crime
    two weeks later, at which point he would have been treated as
    an adult without question.
    Elaborating, the district court cited to the evaluation done at the Iowa
    Medical and Classification Center at Oakdale two months after the crime
    that opined Majors understood the nature and quality of his behavior and
    noted that he had been soliciting help from other inmates regarding how
    to look more psychiatrically ill to aid in his defense. The district court
    acknowledged that the report identified Majors as having “limited insight
    and impaired judgment and being emotionally immature” as well as being
    a loner bullied throughout his childhood. Noting Roby emphasized the
    importance    of   expert   testimony,    the   district   court   referenced
    Dr. Clemmons’ determination that there was nothing about Majors’ age
    14
    that mitigated against a mandatory sentence. “It does not appear to the
    court that the defendant’s age is a mitigating factor in light of the
    contemporaneous assessment and the current psychiatric testimony.”
    Turning to the second factor, the family and home environment, the
    district court noted that “[n]o one point[ed] to any home environment facts
    that influenced the defendant’s behavior.” Indeed, Majors had no juvenile
    criminal history apart from a single offense of possession of alcohol. The
    court referred to the physical abuse by Majors’ father until about the sixth
    grade, noting the father–son relationship subsequently improved and was
    “in good shape” at the time of the crime. Majors himself had denied any
    abuse issues, and his father had contacted the facility where Majors was
    being held numerous times to advocate for greater phone access. The
    district court noted, “Dr. Clemmons also did not identify any family or
    household issues that in her opinion would have mitigated the offense.
    The court concludes that this factor does not mitigate the defendant’s
    conduct.”
    In considering the third factor, the circumstances of the crime and
    attendant youth factors, the district court determined,
    This crime was a solo act by the defendant. There was
    no one involved who encouraged or goaded the defendant into
    acting. There is no indication that he was in any way seeking
    to curry favor with or win approval of any peer group.
    The court relied in part on the Oakdale report and Dr. Clemmons’
    testimony.
    Dr. Clemmons also found no indications of any outside
    influences on the defendant in the planning and execution of
    this crime. In addition, she noted the deliberate nature of the
    crime -- the use of a ski mask and gloves, shoes with no
    identifiable tread, a rifle with a homemade silencer attached
    and a backup weapon -- was supportive of a finding that the
    defendant was acting for himself and not impulsively or at the
    behest of another.
    15
    The district court emphasized the conclusions in the Oakdale report that
    in 2002 Majors “understood the nature and quality of [his] behavior [and] at
    that time he had the capacity to form intent consistent with accountability.”
    The district court concluded that the third factor was not mitigating.
    Regarding the fourth factor, competency to navigate the legal
    system, the district court stated it “fails to see how this factor mitigates in
    the defendant’s favor” and explained why:
    While the crime occurred when the defendant was still a
    minor, the only part of the criminal proceeding that occurred
    while he was a minor was his initial appearance and his
    preliminary hearing at which he successfully obtained
    dismissal of two counts that had been filed initially. The entire
    remainder of this criminal proceeding took place after he had
    attained legal adult status. In addition, he was evaluated for
    competency to stand trial as noted above. This evaluation
    occurred in July 2002 and preceded the bulk of the
    proceedings in this case.       This evaluation found him
    competent to assist in his own defense and to stand trial.
    As an additional consideration, the defendant
    demonstrated an understanding of the legal system that belies
    any disability due to his age. He claimed to be suicidal in
    order to get out of the Taylor County jail. He sought an
    evaluation of his competency in order to try to aid his case.
    He solicited other inmates at Oakdale for ideas on how he
    could appear more worthy of a determination of psychiatric
    incompetency. He tried out various lies in an effort to frame
    an explanation that would allow him to avoid or ameliorate his
    culpability. None of those actions indicate a defendant
    overwhelmed by the system due to his age or immaturity.
    Dr. Clemmons also found nothing in the 2002 evaluation that
    would indicate that the defendant was overwhelmed by the
    system and pointed in her testimony to these additional
    factors as support for that conclusion.
    Finally, the district court turned to the fifth factor, capacity for
    reform, and noted that if it were only considering the defendant at the time
    of the original sentencing in evaluating this factor, his youth and potential
    to reform might weakly mitigate in Majors’ favor.               Focusing on
    Dr. Clemmons’ testimony, the court recognized her concern that Majors
    has never shown empathy for the victims of his crime and his lack of
    16
    empathy “was a trait he brought to prison with him.” The court expressed
    uncertainty over how to consider Majors’ prison conduct when evaluating
    this factor, but concluded, “The only factor that came close to favoring
    mitigation, the possibility of reform, is further weakened if not destroyed
    by his prison conduct.”       Majors had numerous prison disciplinary
    violations before Lyle was decided in 2014. His behavior improved after
    our decision in Lyle, but he committed another major violation (providing
    a fake urine sample to fool a urinalysis) upon returning from his 2018
    resentencing hearing. The court concluded the fifth factor “would mitigate
    in the defendant’s favor, albeit somewhat weakly in the court’s
    assessment.”
    The district court determined “[a] mandatory minimum sentence, in
    the absence of mitigating factors and the presence of ‘a frightening crime,’
    seems appropriate” and that
    after careful consideration of the Lyle factors . . . the
    mandatory minimum sentence for adults convicted of
    attempted murder applies to this defendant and that he
    should be subject to serve 70% of the sentence before
    becoming eligible for parole.
    The court resentenced Majors on the charge of attempted murder to the
    same sentence as before, twenty-five years imprisonment with eligibility
    for parole after serving a mandatory minimum of seventeen and one-half-
    years. The district court concluded that Majors’ sentence for burglary was
    not up for resentencing, and it remained a ten-year sentence that would
    run consecutively to his sentence for attempted murder.
    Majors filed this direct appeal, which we retained.

    II. Standard of Review.
    If the sentence imposed is within the statutory limits, as it is here,
    we review for an abuse of discretion. 
    Roby, 897 N.W.2d at 137
    . As we
    explained in Roby,
    A discretionary sentencing ruling, similarly, may be [an abuse
    of discretion] if a sentencing court fails to consider a relevant
    factor that should have received significant weight, gives
    significant weight to an improper or irrelevant factor, or
    considers only appropriate factors but nevertheless commits
    a clear error of judgment by arriving at a sentence that lies
    outside the limited range of choice dictated by the facts of the
    case.

    preserved for postconviction-relief actions, but ineffective-assistance-of-
    counsel claims can be resolved on direct appeal when the record is
    sufficient to allow a ruling. 1 State v. Wills, 
    696 N.W.2d 20
    , 22 (Iowa 2005).
    III. Analysis.
    Majors argues that the district court abused its discretion by
    imposing a mandatory minimum sentence on remand and that his trial
    1In  State v. Macke, we held that the 2019 amendment to Iowa Code section 814.7
    does not apply to a direct appeal from a judgment and sentence entered before the
    statute’s effective date of July 1, 2019. 
    933 N.W.2d 226
    , 228 (Iowa 2019). Although
    under the current version of Iowa Code section 814.7 Majors would not have a right to
    direct appeal on an ineffective-assistance-of-counsel claim, he did have such a right at
    the time his judgment and sentence was issued on April 2, 2018. As such, we will
    consider Majors’ ineffective-assistance-of-counsel claim in this appeal.
    18
    counsel was ineffective in failing to present expert testimony on the Lyle
    factors at his 2018 resentencing. The State responds that the district
    court properly applied the Lyle factors and that the mandatory minimum
    was supported by expert testimony, while Majors’ own decision to forgo
    retaining a defense expert precludes relief on his ineffective-assistance-of-
    counsel claim.
    A. No Abuse of Discretion. Our decisions have clarified that the
    sentencing court must consider the Miller/Lyle/Roby factors in an
    individualized sentencing hearing if it is contemplating imposing a
    mandatory minimum sentence on a juvenile offender. 
    Roby, 897 N.W.2d at 148
    . The State must prove the defendant’s “irreparable corruption” for
    a life-without-parole sentence. State v. Seats, 
    865 N.W.2d 545
    , 556 (Iowa
    2015).    That proof is not required for a shorter mandatory minimum
    sentence.
    We have given some procedural guidance. Our decision in Roby
    allows district courts to impose minimum terms of incarceration “after a
    complete and careful consideration of the relevant mitigating factors of
    youth.”     
    Roby, 897 N.W.2d at 148
    .      Indeed, we stated that “‘[i]f the
    mandatory minimum period of incarceration is warranted,’ we commanded
    [our judges] to impose the sentence.” 
    Id. at 143
    (alteration in original)
    (quoting 
    Lyle, 854 N.W.2d at 404
    n.10). If the factors are properly applied,
    “the constitutional guarantee against cruel and unusual punishment is
    satisfied.” 
    Id. at 145.
    “[T]he factors must not normally be used to impose
    a minimum sentence of incarceration without parole unless expert
    evidence supports the use of the factors to reach such a result.” 
    Id. at 19
    147. 2 We now turn to addressing what the district court must find in order
    to impose a mandatory minimum sentence for a crime committed under
    age eighteen.
    Our earlier opinions have been criticized for running the risk of
    “mak[ing] it difficult, if not practically impossible, for a sentencing judge
    to ever impose any minimum term of incarceration.” 
    Id. at 151
    (Zager, J.,
    dissenting); see also State v. White, 
    903 N.W.2d 331
    , 337 (Iowa 2017)
    (Mansfield, J., dissenting) (“Our court has extended Miller to all mandatory
    minimums but has yet to say what the substantive standard is. Plainly it
    isn’t ‘irreparable corruption’ . . . . Still, our court hasn’t told district courts
    what that standard is. This isn’t about moving the goal posts. The court
    has yet to erect the goal posts.”). Yet as we indicated in Roby, mandatory
    minimum sentences are permissible. While there is a presumption against
    minimum terms of incarceration for juvenile offenders, we have expressly
    upheld, even commanded, their use if the court concludes that sentence
    is warranted after consideration of the factors. 
    Roby, 897 N.W.2d at 143
    (plurality opinion). Such a conclusion does not need to rise to the level of
    irreparable corruption.
    We reiterate that our role on review is for abuse of discretion. An
    abuse of discretion may exist if the sentencing court fails to consider a
    factor, gives significant weight to an improper factor, or arrives at a
    conclusion that is against the facts. 
    Id. at 138
    . But if the court follows
    our outlined sentencing procedure by conducting an individualized
    2The State stops short of asking us to overrule Roby or Lyle. As we recently noted
    in Goodwin v. Iowa District Court, “We do not ordinarily overrule our precedent
    sua sponte.”

    , 645 n.4 (Iowa 2019) (quoting Estate of McFarlin v. State,

    hearing, applies the Miller/Lyle/Roby factors, and imposes a sentence
    authorized by statute and supported by the evidence, then we affirm the
    sentence. Goodwin v. Iowa Dist. Ct.,

    Seats, 865 N.W.2d at 552
    –53 (explaining our review for abuse of
    discretion and emphasizing the discretionary nature of judges). As we
    stated in Formaro,
    Judicial discretion imparts the power to act within legal
    parameters according to the dictates of a judge’s own
    conscience, uncontrolled by the judgment of others. It is
    essential to judging because judicial decisions frequently are
    not colored in black and white. Instead, they deal in differing
    shades of gray, and discretion is needed to give the necessary
    latitude to the decision-making process.         This inherent
    latitude in the process properly limits our review. Thus, our
    task on appeal is not to second guess the decision made by
    the district court, but to determine if it was unreasonable or
    based on untenable 
    grounds. 638 N.W.2d at 725

    53. We trust the sentencing courts to know, after applying the factors,
    when a mandatory minimum term of incarceration for juvenile offenders
    is warranted.   Such trust is essential to the “respect afforded by the
    appellate process.” 
    Formaro, 638 N.W.2d at 725
    .
    We recently affirmed a twenty-year mandatory minimum on a fifty-
    year sentence for second-degree murder committed by a sixteen-year-old.
    
    Goodwin, 936 N.W.2d at 637
    .         The sentencing court conducted an
    individualized sentencing hearing, relied on expert testimony in applying
    the Miller/Lyle/Roby factors, and imposed a sentence within the statutory
    limits. 
    Id. at 645–47.
    Under circumstances in which two of the factors
    were mitigating, we determined that imposing the twenty-year mandatory
    minimum was neither illegal nor an abuse of discretion. 
    Id. We reach
    the
    21
    same conclusion as to Majors’ seventeen and one-half-year mandatory
    minimum prison term. 3
    Under the first factor, the sentencing court must consider “the age
    of the offender and the features of youthful behavior, such as ‘immaturity,
    impetuosity, and failure to appreciate risks and consequences.’ ” 
    Lyle, 854 N.W.2d at 404
    n.10 (quoting 
    Miller, 567 U.S. at 477
    –78, 132 S. Ct. at
    2468). 4 The district court appropriately noted that Majors was nearly age
    eighteen when he committed the crime in 2002. Majors argues the court
    erred in emphasizing his age and states the fact that he was nearly
    eighteen at the time of the crime is “immaterial to the crucial question
    whether [he] possessed features of maturity beyond his years.” We reject
    his attempt to alter the first factor. The court must consider “the age of
    the offender and the features of youthful behavior,” which explicitly
    articulates that each is a separate consideration under this factor. 
    Id. (emphasis added).
            The district court properly considered the present
    expert testimony of Dr. Clemmons and the 2002 Oakdale psychiatric
    3The  district court, as noted, relied in part on the testimony of the State’s expert
    psychiatrist, Dr. Theresa Clemmons.           Majors’ trial counsel did not argue that
    Dr. Clemmons was unqualified to testify as an expert because she was not a child
    psychologist or child psychiatrist. Nor does Majors’ appellate counsel argue that trial
    counsel provided constitutionally deficient representation by failing to challenge the
    admissibility of Dr. Clemmons’ expert testimony on grounds that she was unqualified.
    “Generally, we have been committed to a liberal view on the admissibility of expert
    testimony.” Ranes v. Adams Labs., Inc., 
    778 N.W.2d 677
    , 685 (Iowa 2010). Indeed, we
    have stated that “an expert does not need to be a specialist in the area of the testimony
    as long as the testimony is within the general area of expertise of the witness.” 
    Id. at 687.
    In Roby, we nowhere specified that the state was limited to using expert testimony of a
    child psychologist or psychiatrist to support a mandatory minimum sentence. Such a
    limitation on expert testimony would make little sense when, as here, the offender was
    age thirty-three at the time of his second resentencing.

    assessment of Majors’ decisional capacity contemporaneously with the
    criminal offenses. The record supports the district court’s determination
    that Majors’ maturity was comparable to a young adult and is not a
    mitigating factor.
    Under the second factor, the sentencing court must consider “the
    particular ‘family and home environment’ that surround the youth.” 
    Lyle, 854 N.W.2d at 404
    n.10 (quoting 
    Miller, 567 U.S. at 477
    –78, 132 S. Ct. at
    2468). “This factor seeks to identify any familial dependency and negative
    influences of family circumstances that can be ingrained on children” and
    considers the impact of all home environments, financial situations, and
    social backgrounds. 
    Roby, 897 N.W.2d at 146
    . Majors, relying on an
    article that outlined resentencing considerations for a potential sentence
    of life without parole, urges that Dr. Clemmons should have interviewed
    family members, reviewed school reports, and utilized social maturity
    scales. 5   Such additional investigation is not required here, especially
    given that Majors was age thirty-three at the time of this second
    resentencing. Dr. Clemmons testified about how Majors had been picked
    on by other kids and noted a report of abuse by his father that ended when
    he was in sixth grade and had since improved. She found no mitigation
    given his childhood or the family environment at the time of the crime, in
    2002, when Majors was living on a quiet street in a loving, two-parent
    household with good relationships with family members. The district court
    considered her expert testimony and noted the absence of “any home
    environment facts that influenced [Majors’] behavior.”                  Unlike many
    youthful offenders raised in troubled home environments, Majors had no

    juvenile criminal record apart from a single offense for possession of
    alcohol and thus had been able to conform his behavior to societal
    expectations before he invaded the Peckham home. The record supports
    the district court’s determination that the second factor is not mitigating
    for Majors.
    Under the third factor, the sentencing court must consider “the
    circumstances of the particular crime and all circumstances relating to
    youth that may have played a role in the commission of the crime.” 
    Lyle, 854 N.W.2d at 404
    n.10. Here, our caselaw directs the sentencing judge
    to give attention to “the juvenile offender’s actual role and the role of
    various types of external pressure.” 
    Roby, 897 N.W.2d at 146
    . As such,
    this factor is more relevant in situations of group participation in a crime.
    
    Id. For homicide
    offenses, this also involves consideration of “the way
    familial and peer pressures may have affected” the defendant. State v.
    Zarate, 
    908 N.W.2d 831
    , 853 (Iowa 2018) (quoting 
    Seats, 865 N.W.2d at 556
    ). “Our sentencing courts can and should consider the heinous nature
    of the crime in evaluating whether to impose a mandatory minimum
    sentence.” 
    Goodwin, 936 N.W.2d at 647
    .
    Majors argues that the court did not give proper weight to his initial
    assertions that he had been dared to commit the crime, had been acting
    under direction of voices in his head due to drug use, and had blacked
    out. However, Dr. Clemmons testified that Majors himself admitted to her
    that he did not commit the crime on a dare, and his claim of being on a
    drug binge was inconsistent with other evidence.         The district court
    appropriately relied on the absence of peer pressure, noting Majors acted
    alone without anyone goading him. The court’s conclusion is supported
    by the expert testimony of Dr. Clemmons, who “found no indications of
    any outside influences . . . in the planning and execution of this crime.”
    24
    Nor was the crime impulsive; to the contrary, Majors acted deliberately
    with careful planning. He observed the Peckham family for years, even
    watching Hollie, the object of his obsession, through bathroom windows.
    He learned their nightly routine, snuck into their home, and hid in Hollie’s
    bedroom closet before emerging to attack her. He wore a ski mask and
    gloves to avoid detection. He brought duct tape presumably to bind her.
    He carried a rifle with a makeshift silencer and a knife as a backup weapon
    to subdue or kill his victims. As we observed in our prior decision, he
    committed a “frightening crime.” 
    Majors, 897 N.W.2d at 125
    . And the
    district court properly relied on present expert testimony and the 2002
    contemporaneous Oakdale psychiatric assessment that at the time of the
    crime Majors understood the nature of his conduct and had the decisional
    capacity to be held accountable. The record supports the district court’s
    determination that the third factor is not mitigating for Majors.
    Under the fourth factor, the sentencing court must consider “the
    challenges for youthful offenders in navigating through the criminal
    process.”   
    Lyle, 854 N.W.2d at 404
    n.10.     “This factor recognizes that
    juveniles are typically less capable than adults at navigating the legal
    process.”   
    Goodwin, 936 N.W.2d at 647
    .        But Majors was an adult
    throughout these criminal proceedings. Dr. Clemmons testified that the
    2002 Oakdale assessment found him competent to assist in his own
    defense, and both a licensed psychologist and psychiatrist in 2002 found
    there was no concern that Majors had diminished capacity or competency.
    The record supports the district court’s determination that Majors
    “demonstrated an understanding of the legal system that belies any
    disability due to his age.”    The record supports the district court’s
    determination that the fourth factor is not mitigating for Majors.
    25
    Under the fifth factor, the sentencing court must consider “the
    possibility of rehabilitation and the capacity for change.” 
    Lyle, 854 N.W.2d at 404
    n.10. This factor typically favors mitigation because juveniles are
    generally more capable of rehabilitation than adults. 
    Roby, 897 N.W.2d at 147
    . Here, the district court appropriately gave weight to expert testimony
    on Majors’ lack of empathy and remorse from his initial arrest to the
    present.      And the district court properly considered Majors’ prison
    disciplinary violations, which as Dr. Clemmons explained were not
    attributable to his youth because he continued to accrue violations as an
    adult.     Even at age thirty-three, and on the same day as his 2018
    resentencing, Majors committed another disciplinary violation. The record
    supports the district court’s determination that the fifth factor is, at best,
    “weakly” mitigating for Majors.
    The district court was unsure what weight to give Majors’ conduct
    in prison. On resentencing, we encourage district courts to consider the
    defendant’s conduct in prison—a sixteen-year span in this case. When
    initially sentencing a juvenile offender shortly after the crime, the district
    court must attempt to predict how the defendant will respond to the future
    opportunities to mature and rehabilitate himself while incarcerated. By
    contrast, we have observed that parole boards have
    “the benefit of seeing the individual offender’s actual behavior,
    rather than having to attempt to predict chances at maturity
    and rehabilitation based on speculation.” As a result, the
    parole board may decide to continue confinement of the
    juvenile “[i]f rehabilitation has not yet occurred” until he or
    she “has demonstrated through his or her own actions the
    ability to appreciate the severity of the crime.” “This is
    consistent with the approach of our prior holdings in the area
    of juvenile sentencing, because it allows for a realistic and
    meaningful opportunity for parole upon the juvenile’s
    demonstration of maturity and rehabilitation.”
    26
    State v. Harrison, 
    914 N.W.2d 178
    , 201 (Iowa 2018) (quoting State v.
    Propps, 
    897 N.W.2d 91
    , 102 (Iowa 2017)). On resentencing, the court, like
    the parole board, can look back and rely on the defendant’s actual
    behavior (good or bad) while incarcerated. 6 See 
    Crooks, 911 N.W.2d at 170
    (considering the “juvenile offender’s progress towards rehabilitation”
    while incarcerated before imposing a new sentence).                  This may benefit
    some defendants.          For example, in State v. Louisell, we affirmed a
    resentence that granted immediate parole eligibility to a juvenile offender
    who had served twenty-six years in prison, noting “Louisell is a model
    inmate who has achieved rehabilitation; grown from a naïve and impulsive
    youngster to a mature, accomplished, and intelligent woman; and
    accepted full responsibility for the crime she committed as a juvenile in
    1987.” 
    865 N.W.2d 590
    , 595 (Iowa 2015). Majors has not been a model
    inmate.
    On balance, we determine the district court did not abuse its
    discretion in applying the foregoing factors to impose the seventeen and
    one-half-year mandatory minimum sentence.                       Importantly, as we
    reiterated in Goodwin, “[o]ur district courts can and should [also] weigh
    public safety (incapacitation), deterrence, and retribution when sentencing
    juvenile offenders for violent felonies.”

    juvenile sentences may still aim to promote additional penological goals,
    including deterrence, retribution, and incapacitation.”); Zarate, 908
    6Courts  in other jurisdictions have held that prison disciplinary violations can be
    considered on resentencing. See, e.g., State v. Swimm, 
    340 S.E.2d 65
    , 70 (N.C. 1986)
    (allowing a defendant’s bad conduct while incarcerated to be considered on resentencing);
    Commonwealth v. Losch, 
    535 A.2d 115
    , 123 (Pa. Super. Ct. 1987) (holding that during
    resentencing the judge “may also allow the prosecution to introduce evidence relating to
    appellant’s bad conduct, if any, since the time that judgment of sentence was last
    
    imposed”). 27 N.W.2d at 854
    –55 (approving consideration of other goals of criminal
    punishment when sentencing juvenile offenders, including incapacitation,
    deterrence, and culpability).
    B. No Ineffective Assistance of Counsel. Majors argues his trial
    counsel had a duty to present an expert witness to testify regarding the
    five sentencing factors. He asserts that his trial counsel’s failure to present
    such an expert amounts to constitutionally deficient representation, that
    is, ineffective assistance of counsel.     The State contends that Majors
    cannot establish that his trial counsel was ineffective for failing to retain
    an expert witness because Majors himself, then age thirty-three, chose not
    to do so.   We begin with our framework for ineffective-assistance-of-
    counsel claims.
    To prevail on an ineffective-assistance-of-counsel claim, the
    claimant must satisfy the two-prong test by proving that his trial counsel
    failed to perform an essential duty and prejudice resulted. State v. Clay,
    
    824 N.W.2d 488
    , 495 (Iowa 2012) (describing the two-prong test for
    ineffective-assistance-of-counsel    claims      set    out   in   Strickland   v.
    Washington, 
    466 U.S. 668
    , 687, 
    104 S. Ct. 2052
    , 2064 (1984)).                   “A
    defendant’s inability to prove either element is fatal.” State v. Graves, 
    668 N.W.2d 860
    , 869 (Iowa 2003).
    Under the first prong, our presumption is that counsel performed
    competently unless the claimant proves otherwise by a preponderance of
    the evidence.     
    Clay, 824 N.W.2d at 495
    .             Counsel’s performance is
    measured objectively against the prevailing professional norms after
    considering all the circumstances.         
    Id. A claimant
    can rebut the
    presumption by showing that counsel failed to perform an essential duty.
    State v. Ross, 
    845 N.W.2d 692
    , 698 (Iowa 2014). More is required than a
    28
    showing that counsel’s trial strategy backfired or the case would have been
    tried differently by another attorney. 
    Id. To establish
    the second prong, prejudice, “the claimant must prove
    by a reasonable probability that, but for counsel’s failure to perform an
    essential duty, the result of the proceeding would have been different.”
    State v. Ary, 
    877 N.W.2d 686
    , 705 (Iowa 2016). This proof does not require
    a showing that counsel’s conduct “more likely than not altered the
    outcome in the case,” but rather that “the probability of a different result
    is ‘sufficient to undermine [our] confidence in the outcome’ of the trial.”
    
    Id. (alteration in
    original) (quoting 
    Graves, 668 N.W.2d at 882
    ).
    The record must be adequate to resolve an ineffective-assistance-of-
    counsel claim on direct appeal. 
    Id. at 704.
    We find that this record is
    adequate, and we hold that Majors’ counsel did not breach an essential
    duty by failing to present a defense expert to testify regarding the
    sentencing factors. Our emphasis in Roby on the importance of presenting
    expert testimony on the Miller/Lyle/Roby factors was directed at the
    State—if the State wants to recommend that the sentencing court impose
    a mandatory minimum sentence, Roby held that an expert is “normally”
    necessary to analyze the factors. 
    Roby, 897 N.W.2d at 148
    . Although the
    option of presenting an expert is available to both parties, the defendant
    does not need expert testimony in order to avoid a mandatory minimum
    sentence.
    Majors himself made the decision not to present an expert during
    the resentencing hearing.     Majors cannot now blame his counsel for
    honoring his own decision. See Schertz v. State, 
    380 N.W.2d 404
    , 413
    (Iowa 1985) (“[A]ppellant cannot now assert a claim of ineffectiveness of
    counsel based primarily on appellant’s own decisions . . . .”); State v.
    Lemburg, 
    257 N.W.2d 39
    , 46 (Iowa 1977) (rejecting a claim of ineffective
    29
    assistance of counsel for the attorney’s alleged failure to litigate certain
    defenses because “[i]t was [the appellant’s] own decision to reject the
    possibilities of these defenses”).
    Calling a defense expert would run the risk that the prosecutor’s
    cross-examination would elicit adverse information. Majors’ counsel made
    a strategic decision to rely on his own cross-examination of the State’s
    expert. “We believe that the question of whether or not to call an expert
    witness is a matter of trial strategy.” Heaton v. State, 
    420 N.W.2d 429
    ,
    432 (Iowa 1988); see also State v. Polly, 
    657 N.W.2d 462
    , 468 (Iowa 2003)
    (“Generally, the decision not to call a particular witness or the defendant
    to testify implicates a reasonable tactical decision.”).    Indeed, Majors’
    counsel referred to that strategy to support his client’s decision to decline
    to keep the record open for a psychiatric examination and a defense expert.
    MR. BOOTH: . . . I’d like to indicate to the court again
    that I’ve again advised Mr. Majors that we could at this point
    ask for the record to remain open in order to get a psychiatric
    examination done. Again on my recommendation it’s my
    understanding that he is declining to have that done at this
    time, Your Honor.
    THE COURT: Mr. Booth, without detailing the legal
    reason, can you place [on] record some reasons for your
    recommendation?
    MR. BOOTH: Well, with respect as indicated in my
    cross-examination, Your Honor, I believe that I was able to
    glean the information that I might otherwise be able to obtain
    through the State’s witness, Your Honor, and in my personal
    opinion and my professional opinion, I believe that that
    should be sufficient, Your Honor. I’m not sure that an
    independent evaluation would provide the same or similar
    opportunity to present information.
    THE COURT: It seems like a reasonable choice of trial
    strategy, Mr. Booth.
    We agree that this was a reasonable trial strategy rather than a
    breach of duty. See State v. Ondayog, 
    722 N.W.2d 778
    , 786 (Iowa 2006);
    
    Polly, 657 N.W.2d at 468
    (holding that the defendant’s ineffective-
    30
    assistance-of-counsel claim failed because “[t]rial counsel’s decision not to
    call [the defendant] to testify clearly was a strategical decision we will not
    second-guess”); State v. McKettrick, 
    480 N.W.2d 52
    , 55 (Iowa 1992);
    
    Heaton, 420 N.W.2d at 432
    (holding defense counsel was not ineffective
    for not calling an expert at trial); Kellogg v. State, 
    288 N.W.2d 561
    , 564
    (Iowa 1980) (“[Defendant] shows no injury from [defense counsel’s]
    decision not to consult the expert witnesses or use them at trial. He has
    failed to carry his burden of proving [defense counsel] was incompetent or
    in any way ineffective on this contention.”).
    We reiterate that these sentencing hearings need not be a battle of
    the experts. A “basic proposition” regarding this process is that “juvenile
    sentencing hearings are not entirely adversarial. The goal is to craft a
    ‘punishment that serves the best interests of the child and of society.’ ”
    
    Roby, 897 N.W.2d at 144
    (quoting 
    Lyle, 854 N.W.2d at 402
    ). Requiring
    the defense to present an expert in every juvenile sentencing case would
    not serve that goal.
    We hold Majors’ defense counsel had no duty to present an expert
    to testify regarding the Miller/Lyle/Roby factors. Given that Majors failed
    to prove the first element required to prevail on an ineffective-assistance-
    of-counsel claim, a breach of duty, we end our analysis there. See 
    Graves, 668 N.W.2d at 869
    (“A defendant’s inability to prove either element is
    fatal.”).
    IV. Disposition.
    For the foregoing reasons, we affirm the district court’s resentencing
    order and judgment of sentence.
    AFFIRMED.

    concurring specially), I conclude the district court did not abuse its

    Christensen, C.J., joins this special concurrence.
    33
    #18–0563, State v. Majors
    APPEL, Justice (dissenting).
    I respectfully dissent.
    The sentencing hearing in this case does not remotely resemble that
    contemplated by State v. Roby, 
    897 N.W.2d 127
    (Iowa 2017), State v. Seats,
    
    865 N.W.2d 545
    (Iowa 2015), State v. Lyle, 
    854 N.W.2d 378
    (Iowa 2014),
    and State v. Null, 
    836 N.W.2d 41
    (Iowa 2013). The overarching problem is
    that the district court failed to recognize the principles of developmental
    child psychology that underlie our juvenile sentencing cases and entered
    a sentencing order that failed to apply the proper framework to this case.
    Further, counsel for Jarrod Majors made no effort to present the law or to
    show, through competent expert testimony, how the law related to the
    facts at hand. As a result, the sentence in this case should be vacated and
    the matter remanded for resentencing.
    I. By Failing to Recognize the Developmental Child Psychology
    Underpinning Our Caselaw and the Proper Framework for Considering
    Juvenile Culpability, the District Court Committed Reversible Error.
    A. The Need for Qualified Expert Testimony on Developmental
    Child Psychology in Cases Where Juvenile Offenders Face the
    Possibility of the Imposition of Mandatory Adult Minimum Sentences.
    The basic framework of the United States Supreme Court on juvenile
    justice   fundamentally       turns     on    concepts     of   developmental       child
    psychology as articulated in the recent seminal trilogy of cases: Miller v.
    Alabama, 
    567 U.S. 460
    , 
    132 S. Ct. 2455
    (2012), Graham v. Florida, 
    560 U.S. 48
    , 
    130 S. Ct. 2011
    (2010), and Roper v. Simmons, 
    543 U.S. 551
    , 
    125 S. Ct. 1183
    (2005). 7
    7“Developmental   psychology, broadly defined, concerns the scientific study of
    changes in physical, intellectual, emotional, and social development over the life cycle.”
    Laurence Steinberg & Elizabeth Cauffman, The Elephant in the Courtroom: A
    34
    We applied child developmental psychology under the article I,
    section 17 cruel and unusual punishment provision of the Iowa
    Constitution in Roby, Seats, Lyle, and Null. Under our caselaw, the state
    must show in an individualized hearing that a juvenile criminal defendant
    facing a mandatory adult sentence falls outside the norm of most juveniles,
    where age is presumptively considered a mitigating factor on the critical
    issue of culpability.
    In Roby, we explored the contours of an individualized hearing
    required before the state may apply a mandatory adult minimum sentence
    against a juvenile offender. We noted that the mitigating developmental
    factor of “age of the offender and the features of youthful behavior” is most
    meaningfully applied when based on qualified professional assessments of
    the    offender’s     decision-making         capacity     utilizing     the    expert’s
    “developmental and clinical knowledge.”

    (first
    quoting 
    Lyle, 854 N.W.2d at 404
    n.10; then quoting Elizabeth S. Scott et
    al., Juvenile Sentencing Reform in a Constitutional Framework, 88 Temp. L.
    Rev. 675, 697 (2016) [hereinafter Scott et al., Juvenile Sentencing Reform]).
    As authority for its reliance on qualified professional assessments, the
    Roby court cited the work of four leading authorities in the area: Thomas
    Grisso, Marsha Levick, Elizabeth Scott, and Laurence Steinberg. 8 These

    L. 389, 391 (1999) [hereinafter Steinberg & Cauffman, Adjudication of Youthful Offenders].
    8These   experts continue to provide valuable research on the issue of juvenile
    development and the criminal justice system. See generally Thomas Grisso et al.,
    Juveniles’ Competence to Stand Trial: A Comparison of Adolescents’ and Adults’ Capacities
    as Trial Defendants, 27 Law & Hum. Behav. 333 (2003) (evaluating data indicating

    trial); Thomas Grisso & Antoinette Kavanaugh, Prospects for Developmental Evidence in
    Juvenile Sentencing Based on Miller v. Alabama, 22 Psychol., Pub. Pol’y, & L. 235, 240

    new sentencing cases); Marsha Levick & Neha Desai, Still Waiting: The Elusive Quest to
    Ensure Juveniles a Constitutional Right to Counsel at All Stages of the Juvenile Court

    four leading authorities on child development and the law state that
    “[b]ecause the Miller factors are based upon developmental constructs,
    expert assessments by forensic child clinical psychologist or psychiatrists
    are required to inform courts making sentencing decisions.” Scott et al.,
    Juvenile Sentencing Reform, 88 Temp. L. Rev. at 695 (emphasis added). 9
    Scott and her colleagues further emphasize the importance of child
    development expertise. According to these leading authorities, “[g]eneral
    forensic mental health professionals who evaluate adults for criminal
    courts are usually not qualified to undertake these assessments.” 
    Id. Yet, that
    is exactly what occurred in this case. The State’s expert
    was a staff psychiatrist with the department of corrections.                    She was
    named as an expert by the State at the last minute in this matter, on
    Process, 60 Rutgers L. Rev. 175 (2007) (arguing that juveniles need counsel at all points
    in legal proceedings as they generally do not understand their rights or the proceedings

    9The  American Academy of Child and Adolescent Psychiatry recommends that
    professionals conducting assessments should have adequate experience, education, and
    training, including knowledge of normal growth and development and child
    psychopathology. Louis J. Kraus et al., Am. Acad. Child & Adolescent Psychiatry, Practice

    Adolescence Psychiatry 1299, 1304 (2011).

    January 30, 2018, conducting Majors’ psychiatric evaluation two weeks
    later on February 13. The resentencing hearing was initially scheduled for
    February 20 and only later was continued to March 5.            She worked
    primarily with adults and only came in contact with juveniles in the
    corrections system.    There is nothing in the record to establish her
    qualifications with regard to child developmental psychology. Indeed, as
    will be shown below, the State’s expert demonstrated little familiarity with
    child developmental psychology.
    In effect, while the State’s expert was testifying at the March 5
    hearing, it was in fact the prosecutor testifying through repeated use of
    leading questions that suggested the answer. By way of example,
    Q. Through your evaluation, as well as a review of the
    record, you found no psychiatric or mental health illness that
    would have impacted his ability to understand what he was
    doing at the time of the crime; correct? A. That’s correct.
    ....
    Q. Is it also a concern in terms of rehabilitation if the
    defendant doesn’t take full responsibility for his actions or
    minimizes his conduct? A. This is kind of where the concern
    for the treatment kind of comes up in terms of
    rehabilitation. . . . That’s kind of where the rehabilitation is
    founded upon.
    ....
    Q. Taking that one step further, if one takes a little
    responsibility but kind of minimizes what he did, it’s going to
    minimize them because they’re going to get out or
    rehabilitation programs; correct? A. Correct.
    ....
    Q. Combined with a lack of empathy for the victims,
    that doesn’t give us a very good forecast for his rehabilitation;
    would that be fair? A. That would be fair.
    ....
    37
    Q. So in some respects the judicial declaration at 18 is
    a demarcation point and somewhat of an partial line being
    drawn; would that be fair? A. That would be fair.
    Q. If you’re going to draw the line there, then if that’s
    the best way the line gets drawn, then what you’re saying is
    the development that this defendant would have had in the 15
    days from commission of crime until he reached age of
    majority would have been minimal, if any; correct? A. That’s
    correct.
    Q. So in terms of mitigating his responsibility for the
    crime, at best it would have minimal mitigating value; would
    that be fair? A. Yes.
    While Majors’ counsel inexplicably did not object to the expert’s
    qualifications or to her testimony, the testimony of the State’s expert is
    entitled to little or no weight by the court. The repeatedly leading nature
    of the questioning undermines any credibility in the testimony.          See
    Denniston Partridge Co. v. Romp, 
    244 Iowa 204
    , 210, 
    56 N.W.2d 601
    , 604
    (1953) (“While the absence of proper objection left the answers in the
    record for what they were worth, we think the weight of such testimony is
    very slight.”). Further, the lack of qualifications in child developmental
    psychology undermines her testimony. State ex rel. Leas in re O’Neal, 
    303 N.W.2d 414
    , 421 (Iowa 1981) (“[I]t is not sufficient that the expert be
    generally qualified in the area of inquiry; ‘sufficient data must appear upon
    which an expert judgment can be made (on the specific question
    propounded,) and if absent, the opinion is incompetent.’ ” (quoting
    Holmquist v. Volkswagen of Am., Inc., 
    261 N.W.2d 516
    , 524 (Iowa Ct. App.
    1977))).
    We have emphasized that “[p]erceptions applicable to adult behavior
    cannot normally be used to draw conclusions from juvenile behavior.”
    
    Roby, 897 N.W.2d at 147
    ; see also Jenny E. Carroll, Brain Science and the
    Theory of Juvenile Mens Rea, 
    94 N.C. L
    . Rev. 539, 598 (2016) (“I am not
    asserting either that adolescent offenders are categorically incapable of
    38
    achieving any particular mens rea or should be rendered blameless by
    their immaturity. Quite the contrary—I am arguing that, like all offenders,
    adolescents should be held accountable for the mens rea they actually
    achieved.”); Marsha Levick et al., The Eighth Amendment Evolves: Defining
    Cruel and Unusual Punishment Through the Lens of Childhood and
    Adolescence, 15 U. Pa. J.L. & Soc. Change 285, 293 (2012) (“Emerging
    research in [the field of developmental psychology] indicates that
    developmental immaturity consists of four components distinguishing
    adolescents from adults: independent functioning, decision-making,
    emotion regulation, and general cognitive processing.”). But by using a
    psychiatrist with no demonstrable child development training and whose
    clinical experience was largely with adults, the State’s presentation was
    more akin to a sentencing process that might be appropriate for an adult
    but assuredly was inappropriate for a juvenile. This is evidenced by a
    number of specific errors and omissions in the expert testimony, which
    was erroneously relied upon in the district court’s ruling.
    B. “First and Foremost”: Direction Regarding Consideration of
    the Mitigating Factors of Youth. Lyle states in clear language, “First
    and foremost, the time when a seventeen-year-old could seriously be
    considered to have adult-like culpability has 
    passed.” 854 N.W.2d at 398
    (emphasis added). The first-and-foremost principle is entirely absent from
    the testimony of the expert and from the district court’s opinion. First and
    foremost, lessened culpability for all juveniles under eighteen is the norm,
    not   the   exception.   First   and   foremost,   because    “children   are
    constitutionally different than adults,” they ordinarily cannot be held to
    the same standard of culpability as adults in criminal sentencing. 
    Miller, 567 U.S. at 470
    –72, 132 S. Ct. at 2464–65. First and foremost, the default
    rule is that children are not subject to mandatory minimums of
    39
    incarceration. 
    Roby, 897 N.W.2d at 144
    (citing 
    Null, 836 N.W.2d at 74
    ).
    First and foremost, “[m]itigation normally is warranted in all crimes.” 
    Id. at 146.
    As noted by Scott and her colleagues, “[g]iven the background
    principle embraced by the [United States] Supreme Court that most youths
    are immature, the prosecutor carries a substantial burden.” Scott et al.,
    Juvenile Sentencing Reform, 88 Temp. L. Rev. at 696. According to Scott
    and Steinberg, “a strong presumption that mitigation applies categorically
    to the juvenile offenders avoids innocent errors and more pernicious
    influences that may distort individualized determinations.” Elizabeth S.
    Scott & Laurence Steinberg, Rethinking Juvenile Justice 141 (2008)
    [hereinafter Scott & Steinberg, Rethinking Juvenile Justice].
    Roby embraces these principles. Under Roby, expert testimony may
    be used to show that the normative mitigation principle does not apply by
    showing that the particular juvenile offender “possessed features of
    maturity beyond his or her 
    years.” 897 N.W.2d at 146
    . The State has the
    burden of showing the unusual or exceptional maturity, the prerequisite
    showing for departure from child developmental norms. The State must
    show that the juvenile’s maturity is so exceptional and so outside the norm
    that an adult mandatory sentence is appropriate.
    The State’s expert testified that she “found nothing about Majors’
    age at the time of the offense that mitigated against a mandatory
    sentence.” But that is not the child development framework presented in
    Roby.     Under the Roby framework, juveniles under eighteen are less
    culpable than adults unless expert testimony shows maturity beyond his
    or her years. 
    Id. at 146.
    The record should not be viewed through the lens
    ordinarily applied to adult behavior, but through the lens of child
    developmental psychology principles. 
    Id. at 147.
                                        40
    No such expert testimony was offered in this case.       Instead, the
    State’s expert, through highly leading questions, flipped the Roby
    framework on its head, put the burden of mitigation based on age on
    Majors, and then declared that she had found nothing to establish
    mitigation. She ignored, or more likely given her lack of qualifications was
    unaware of, the normative developmental principle that teenagers,
    including those that are seventeen years of age, are categorically less
    culpable than adults absent expert testimony that the offender “possessed
    features of maturity beyond his or her years.” 
    Id. She occasionally
    cited
    facts in the record germane to child development, but these facts were not
    analyzed through the lens of child developmental psychology as required
    by our caselaw.
    Although not explicit, the district court ruling in this case appears
    to have flipped the burden as well. It certainly does not start from the
    general presumption of mitigation for seventeen-year-olds. Indeed, in key
    passages, it reads very much like an ordinary adult sentencing order. If
    the district court had operated from the assumption that “[f]irst and
    foremost, the time when a seventeen-year-old could seriously be
    considered to have adult-like culpability has passed” and the “children are
    different” framework, the numerous and repeated shortcomings in the
    State’s expert testimony would have been viewed as problematic. 
    Lyle, 854 N.W.2d at 398
    ; see 
    Miller, 567 U.S. at 470
    –72, 132 S. Ct. at 2464–65.
    A clear example of the district court’s endorsement of legal error arising
    from expert testimony is presented in the erroneous treatment of a
    seventeen-year-old as nearly an adult contrary to established caselaw.
    Even if it is unclear that the district court applied the wrong legal
    standard, reversal and remand is appropriate to clarify the basis of the
    court’s ruling. See State v. Showens, 
    845 N.W.2d 436
    , 449–50 (Iowa 2014)
    41
    (finding reversal and remand proper where unsure whether the district
    court applied correct legal standard).
    C. Erroneous Treatment of Seventeen-Year-Old as Nearly an
    Adult Contrary to Established Caselaw.
    1. Introduction.    The State’s expert and the district court
    erroneously analyzed the impact of Majors’ age. They emphasized that
    Majors’ offense occurred fifteen days before he turned eighteen and then
    suggested that the proper analytical approach was to determine whether
    fifteen days of additional life would have had any impact on Majors’
    decision-making.
    2. Contrary to principles of child developmental psychology.    This
    bizarre analytical framework is completely inconsistent with the principles
    of child developmental psychology that underlie Miller, Graham, and Roper
    and Roby, Seats, Lyle, and Null. The line for the presumption of lessened
    culpability has been placed at eighteen years of age, many years inside the
    scientific boundaries of the developing child. As noted by the Supreme
    Court, the age of eighteen comes from history and social meaning of age,
    but not from developmental psychology. 
    Roper, 543 U.S. at 569
    , 125 S. Ct.
    at 1195. This presumption exists in part because the law assumes that a
    person eighteen years of age has the freedom to extricate themselves from
    unfavorable social environments and in part because society generally
    accepts eighteen as a threshold separating children from adults for a wide
    variety of activities. 
    Id. But with
    respect to persons under the age of
    eighteen, “the presumption of immaturity can be applied confidently to
    most persons in the group.” Scott & Steinberg, Rethinking Juvenile Justice
    at 140.
    It is simply wrong and completely inconsistent with developmental
    psychology, however, to conclude that a seventeen-year-old is almost
    42
    eighteen and therefore not entitled to the presumption of immaturity. It is
    well established that a lot of relevant social and emotional development
    related to culpability occurs in juveniles after the age of eighteen and
    through the mid-twenties. 10             According to two leading scholars in
    adolescent development and the law, Scott and Steinberg, “[t]he research
    clarifies that substantial psychological maturation takes place in the
    middle of late adolescence and even into early adulthood.” 
    Id. at 60.
    Thus,
    Scott and Steinberg emphasize that “adolescents, even at age sixteen and
    seventeen, are immature in their psychosocial and emotional development,
    and this likely affects their decisions about involvement in crime in ways
    that distinguish them from adults.” 
    Id. at 131.
    Recently, Steinberg and
    his colleagues stated,
    Over the past decade, developmental psychologists and
    neuroscientists have found that biological and psychological
    development continues into the early twenties, well beyond
    10The leading exploration of developmental psychology for “emerging adults” is
    Jeffrey Jensen Arnett, Emerging Adulthood: A Theory of Development from the Late Teens
    Through the Twenties, 55 Am. Psychologist 496 (2000). The article broadly examines the
    subjective and objective differences of individuals between eighteen and twenty-five, as
    compared to adolescents and youth adults. See also Elizabeth Cauffman & Laurence
    Steinberg, (Im)maturity of Judgment in Adolescence: Why Adolescents May Be Less
    Culpable than Adults, 18 Behav. Sci. & L. 741, 758 (2000) (“The present study indicates
    that . . . psychosocial characteristics continue to develop during late adolescence, and
    that these changes result in significant declines in antisocial decision-making . . . [which]
    are appreciable enough to warrant drawing a legal distinction.”). The last twenty years of
    research have supported Arnett’s view that the brains of teens continue to evolve until
    the mid-twenties. See, e.g., Alexandra O. Cohen et al., When Is an Adolescent an Adult?:
    Assessing Cognitive Control in Emotional and Nonemotional Contexts, 27 Psychol. Sci. 549,
    559–60 (2016) (suggesting young adults have lower cognitive capacity in emotional
    situations when compared to adults); Josh Gupta-Kagan, The Intersection Between Young
    Adult Sentencing and Mass Incarceration, 
    2018 Wis. L
    . Rev. 669 (2018) (canvassing both
    the scientific literature about young adult development and examining it in light of
    sentencing and mass incarceration); Elizabeth S. Scott et al., Young Adulthood as a
    Transitional Legal Category: Science, Social Change, and Justice Policy, 85 Fordham L.
    Rev. 641 (2016) (examining the neuroscientific, psychological, and sociological research
    on young adulthood as applied in a criminal justice context); Kelsey B. Shust, Comment,
    Extending Sentencing Mitigation for Deserving Young Adults, 104 J. Crim. L. & Criminology

    culpability).

    the age of majority. Recently, researchers have found that
    eighteen- to twenty-one-year-old adults are more like younger
    adolescents than older adults in their impulsivity under
    conditions of emotional arousal.
    Elizabeth S. Scott et al., Young Adult as a Transitional Legal Category:
    Science, Social Change, and Justice Policy, 85 Fordham L. Rev. 641, 642
    (2016) [hereinafter Scott et al., Transitional Legal Category].
    3. Contrary to caselaw.    The caselaw does not support the just-
    short-of-eighteen analysis of the State’s expert that was erroneously
    adopted by the district court.    In Roper, the Supreme Court made no
    mention of the just-short-of-eighteen argument even though Roper was
    just a few months shy of his eighteenth birthday when he committed a
    brutal murder. See 
    Roper, 543 U.S. at 619
    , 125 S. Ct. at 1223. Nothing
    in United States Supreme Court caselaw suggests that a just-short-of-
    eighteen analysis is appropriate in considering the culpability of youth in
    the application of cruel and unusual punishment concepts.
    Our Iowa caselaw is clear on this point. In Null, for instance, we
    cited Steinberg and others for the proposition that “identity development,
    which is often accompanied by experimentation with risky, illegal, or
    dangerous activities, occurs in late adolescence and early 
    adulthood.” 836 N.W.2d at 55
    (citing Scott & Steinberg, Rethinking Juvenile Justice at 50–
    52).   We further noted that “[t]he research clarifies that substantial
    psychological maturation takes place in middle and late adolescence and
    even into early adulthood.”    
    Id. (quoting Scott
    & Steinberg, Rethinking
    Juvenile Justice at 60).
    Then in Lyle, the district court sentenced a seventeen-year-old to an
    adult mandatory minimum for the crime of second-degree 
    robbery. 854 N.W.2d at 380
    . We vacated the sentence and remanded the case for an
    individualized hearing on whether the adult mandatory sentence could be
    44
    imposed on Lyle. 
    Id. at 404.
    In Lyle, we cited Graham for the proposition
    that persons under eighteen had “categorically diminished culpability.” 
    Id. at 398
    (citing 
    Graham, 560 U.S. at 71
    –75, 130 S. Ct. at 2028–30).
    We again returned to the subject in Seats, where we considered a
    sentencing proceeding involving a seventeen-year-old offender convicted of
    first-degree murder and first-degree 
    burglary. 865 N.W.2d at 549
    . In
    sentencing Seats to life in prison without parole, the district court
    emphasized that Seats was a seventeen-year-old, thereby raising the
    “almost eighteen” argument. 
    Id. at 556–57.
    In response, we stated that we recognized that “in Roper, the line
    between being a juvenile and an adult was drawn for cruel and unusual
    punishment purposes at eighteen years of age.”          
    Id. at 556–57
    (citing
    
    Roper, 543 U.S. at 574
    , 125 S. Ct. at 1197–98). Yet, we cited Null for the
    proposition that current science demonstrated that the brain continued to
    develop into the early twenties. 
    Id. at 557
    (citing 
    Null, 836 N.W.2d at 55
    ).
    We repeated the findings of Scott and Steinberg that “adolescents, even at
    the age sixteen and seventeen, are immature in their psychosocial and
    emotional development, and this likely affects their decisions about
    involvement in crime that distinguishes them from adults.” 
    Id. at 557
    (quoting Scott & Steinberg, Rethinking Juvenile Justice at 131). Then we
    declared, “In light of the science, the fact that a defendant is nearing the age
    of eighteen does not undermine the teachings of Miller and Null.”            
    Id. (emphasis added).
    Finally, in Roby, the defendant was sixteen and seventeen years old
    when he committed the crimes of sexual abuse in the second and third
    degrees. We again cited the work of developmental psychologists for the
    proposition that “developmental changes . . . continue into the mid-
    twenties.” 
    Roby, 897 N.W.2d at 145
    (quoting Scott et al., Transitional Legal
    45
    Category, 85 Fordham L. Rev. at 647). We declared that “age is not a
    sliding scale that necessarily weighs against mitigation the closer the
    offender is to turning eighteen years old at the time of the crime.” 
    Id. But that,
    of course, is exactly what the State’s expert did, and the approach
    the district court uncritically adopted.
    In a footnote, the majority cites Steinberg for the proposition that
    cognitive development of sixteen-year-olds is often fully developed. See
    Laurence Steinberg et al., Are Adolescents Less Mature than Adults?
    Minors’ Access to Abortion, the Juvenile Death Penalty, and the Alleged APA
    “Flip-Flop,” 64 Am. Psychologist 583, 586–87 (2009) (“Studies that have
    examined logical reasoning abilities in structured situations and basic
    information processing skills, for instance, find no appreciable differences
    between adolescents age 16 and older and adults[.]”). But the majority is
    apparently unaware that Steinberg, consistent with the consensus social
    science, emphasizes that psychosocial and emotional development
    continues into the mid-twenties and that this delay in development
    impacts criminal culpability. See Scott & Steinberg, Rethinking Juvenile
    Justice at 60; see also Scott et al., Transitional Legal Category, 85 Fordham
    L. Rev. at 647 (“[B]ecause development of brain systems that regulate
    impulse control is more protracted, continuing into the early twenties, a
    period of vulnerability to risky behavior results . . . [and may be likened to
    an] ‘accelerator’ [being] pressed to the floor, [while] a good ‘braking system’
    is not yet in place.” (Footnote omitted.)). Further, the majority fails to
    recognize that our caselaw, and that of the United State Supreme Court,
    embraces the work of Steinberg and his colleagues for precisely the
    opposite proposition advanced by the majority and supported by the
    footnote.   See 
    Roper, 543 U.S. at 570
    , 125 S. Ct. at 1196; 
    Seats, 865 N.W.2d at 557
    . Finally, the majority fails to tell the reader that Roby,
    46
    Seats, Lyle, and Null stand for the proposition that even those approaching
    eighteen years of age as a general rule have diminished culpability.
    In the end, the district court was misled by an unqualified expert.
    “Forensic professionals conducting assessments for a sentencing hearing
    must be sure to keep up with relevant post-Miller legislation and case law
    in the jurisdiction where the hearing is taking place.” Kimberly Larson et
    al., Miller v. Alabama: Implications for the Forensic Mental Health
    Assessment at the Intersection for Social Science and the Law, 39 New Eng.
    J. on Crim. & Civ. Confinement 319, 330 n.60 (2013) [hereinafter Larson
    et al., Mental Health Assessments]. As a nonlawyer medical professional
    with very limited professional interaction with juveniles who was
    designated at the last minute to testify as an expert for the first time in a
    sentencing hearing involving a juvenile offender, the State’s expert,
    perhaps, can be forgiven for her lack of knowledge about child and young
    adult developmental psychology and the applicable caselaw. She simply
    was clueless when the prosecutor asked her leading questions that led the
    expert to testify in a manner contrary to applicable Iowa Supreme Court
    precedent and in total disregard of the findings of child developmental
    psychology.
    The district court expressly embraced the “almost eighteen”
    reasoning of the State’s expert in considering age, which it characterized
    as “the most important factor” under our decisions. Through the use of
    the “almost eighteen” framework, the district court, like the State’s expert,
    eviscerated the importance of age by essentially treating Majors as an
    adult. When a district court unlawfully considers a factor in making a
    decision, an abuse of discretion is present. State v. Zarate, 
    908 N.W.2d 831
    , 856 (Iowa 2018) (“ ‘[I]f a sentencing court fails to consider a relevant
    factor that should have received significant weight, gives significant weight
    47
    to an improper or irrelevant factor, or considers only appropriate factors
    but nevertheless commits a clear error of judgment’ a discretionary
    sentencing ruling may be an abuse of discretion.” (quoting 
    Roby, 897 N.W.2d at 138
    )); State v. Knight, 
    701 N.W.2d 83
    , 85 (Iowa 2005) (“[T]he use
    of an impermissible sentencing factor is an abuse of discretion and
    requires resentencing.”).
    D. Failure to Conduct Meaningful Evaluation.               In order to
    overcome the presumption of diminished culpability for youth, the State
    must ordinarily present a meaningful professional evaluation of the
    defendant. Consistent with principles of child developmental psychology,
    we have taken a broad approach to environmental factors, including such
    things as parental neglect, drug or alcohol use, prior exposure to violence,
    and age-related susceptibility to psychological or emotional damage.
    
    Seats, 865 N.W.2d at 556
    . In conducting a forensic evaluation of a juvenile
    offender, Scott and her colleagues declare that the child development
    expert evaluating the culpability of juvenile defendants must engage in
    “skilled interviewing of the youth, and of family members, teachers, and
    peers who have observed the youth’s functioning.” Scott et al., Juvenile
    Sentencing Reform, 88 Temp. L. Rev. at 697. This should be done in light
    of “a comprehensive review of records of the youth’s past behavior in
    various social situations (e.g. school, rehabilitation settings).” 
    Id. Instead, the
    State’s expert selectively gathered documents available
    at the department of corrections and in the court file. She assiduously
    gathered documents regarding each and every discipline violation. But
    contrary to the child developmental psychology authorities, she did not
    thoroughly interview the parents.       Contrary to the child development
    authorities, she did not thoroughly interview teachers. Contrary to the
    child development authorities, she did not thoroughly interview Majors’
    48
    peers. She appears to have thoroughly gathered information that might
    reflect adversely on Majors but did not engage in the kind of thorough
    exploration that is required for meaningful evaluation according to Scott
    and her colleagues.
    I suppose one might argue that the thorough investigation
    demanded by Scott and her colleagues would be inefficient and yield very
    little. The State has limited resources, so the argument goes, and cannot
    be expected to reach out beyond the department of corrections and the
    court system in the gathering of materials for the evaluation of a juvenile
    offender facing an adult mandatory minimum sentence. But that just is
    not the way things are done, right?         Can’t we simply follow our gut
    instincts, with a limited factual review?
    No! Put simply, the law requires more. The State has the burden of
    showing that a juvenile offender is an exceptional person that falls outside
    ordinary norms that mitigate culpability. This burden is very difficult to
    meet without a thorough investigation of the family and social background
    of a juvenile offender, as demanded by Scott and her colleagues.
    Since circumstances vary from individual to individual, it is difficult
    to draw a line in the sand to say that a particular review is sufficient or
    not. At some point the investigation supporting an evaluation must come
    to an end, and at some juncture there are diminishing returns. There is,
    for instance, no requirement that an expert interview all family members,
    every teacher, and every peer. But what is required is that a reasonable
    review be conducted. That did not occur in this case.
    The record shows that Majors was abused by his father up until
    sixth grade.    Certainly this is a fact that any child developmental
    psychologist would want to explore and develop.        See, e.g., Samantha
    Buckingham, Reducing Incarceration for Youthful Offenders with a
    49
    Developmental Approach to Sentencing, 46 Loy. L.A. L. Rev. 801, 850 (2013)
    (noting the limitations of developmental science and generalizations
    because of varying experiences in individuals due to their sociological
    backgrounds, including exposure to abuse, trauma, or neglect); David
    Dante Troutt, Trapped in Tragedies: Childhood Trauma, Spatial Inequality,
    and Law, 101 Marq. L. Rev. 601, 626 (2018) (“As children’s brains react to
    traumatic stressors, processes are trigged that affect different systems in
    the body . . . rang[ing] from behavioral self-regulation problems and mental
    illness . . . [to] risk of alcohol or substance abuse . . . .”   (Footnotes
    omitted.)). See generally Jennifer E. Lansford et al., Early Physical Abuse
    and Later Violent Delinquency: A Prospective Longitudinal Study, 12 Child
    Maltreatment 233 (2007) (citing the link between early physical abuse and
    later aggression and delinquency and other social and psychological
    problems, including depression and anxiety). The State’s expert in Majors’
    case made no such effort.
    The record also shows that Majors transferred out of the Bedford
    Public Schools and enrolled in an alternative school at age fifteen.
    Something substantial is going on here. Any child developmental mental
    health professional would thoroughly review the attendant circumstances
    to figure out what was going on. See, e.g., Substance Abuse & Mental
    Health Servs. Admin., U.S. Dep’t of Health & Hum. Servs., Screening and
    Assessment of Adolescents in Juvenile Justice Setting, in Screening and
    Assessing   Adolescents     for   Substance   Use   Disorders,   Treatment
    Improvement Protocol (TIP) Series 45 (2012) (noting that screening and
    assessing adolescents in a juvenile justice setting is a complex task and
    the evaluator must be alert to the comorbidities a juvenile experiencing
    substance abuse may encounter, such as poor school performance). Yet,
    50
    the State’s expert made no serious effort to understand what was going on
    here.
    And this isn’t the only issue of concern that the expert did not
    properly consider.    Majors suffered from scoliosis, or curvature of the
    spine. It was apparently serious enough to require surgical intervention
    and the placement of rods in his back at the age of twelve. Later, he had
    to wear a brace of some kind. Although Majors was inclined to athletics,
    he could no longer engage in contact sports in small town Iowa middle and
    high schools. What was the impact of this development? Did it contribute
    to feelings of anger and loneliness?              See Ryszard Tomaszewski &
    Magdalena Janowska, Psychological Aspects of Scoliosis Treatment in
    Children, in Recent Advances in Scoliosis 301, 301–03 (Theodoros Grivas
    ed., 2012) (noting the effects of scoliosis compound on existing challenges
    of adolescence, creating altered perceptions of body image, anger,
    embarrassment,       and    impairment       of   social    functioning);   Despina
    Sapountzi-Krepia     et    al.,   The   Experience     of    Brace   Treatment   in
    Children/Adolescents with Scoliosis, 1 Scoliosis art. 8 (2006) (noting that
    scoliosis can be a risk factor for psychological impairment in children and
    adolescents, particularly in those undergoing brace treatment). How did
    this affect Majors? The expert gives us no insight.
    The record further indicates that as a child, Majors was mocked by
    his peers because his family raised chickens in the country. According to
    his discharge summary from Oakdale in 2003, Majors “seem[ed] to be an
    angry individual who tend[ed] to ruminate on being ridiculed by other
    children in the past and tend[ed] to lose his temper when things [did] not
    go his way.” A nurse additionally noted that Majors “appear[ed] to have
    many years of anger bottled up from teasing and abuse from peers.” He
    was “tearful” when describing past experience of abuse and teasing, and
    51
    his file notes Majors was “very immature (emotionally) and doesn’t cope
    well with stress or problems.” The file suggests that Majors “might benefit
    from therapy targeting interpersonal relationships, difficulties, and anger.”
    These are the kinds of things that would interest a child developmental
    psychologist or psychiatrist. See Anat Brunstein-Klomek et al., Bullying,
    Depression, and Suicidality in Adolescents, 46 J. Am. Acad. Child &
    Adolescent Psychiatry 40, 40–41 (2007) (noting that studies examining the
    relationship between bullying, and depression and suicidality, found
    victims were more likely to manifest more depressive symptoms,
    psychological distress, and both suicidal ideations and suicide attempts
    than nonvictims); Nicholas Carlisle & Eric Rofes, School Bullying: Do Adult
    Survivors Perceive Long-Term Effects?, 13 Traumatology 16, 17–18, 23
    (2007) (noting studies that determined the common emotional and
    behavioral responses to bullying are vengefulness, anger, self-pity,
    anxiety, low self-regard, and school absenteeism and discussing how some
    symptoms remain even after bullying as stopped, and how anger and
    vengeful ideation are a long-term effect of survivors of bullying); Calli
    Tzani-Pepelasi, Childhood Bullying Can Cause Lifelong Psychological
    Damage—Here’s How to Spot the Signs and Move On, The Conversation,
    (last updated August 8, 2018), http://theconversation.com/childhood-
    bullying-can-cause-lifelong-psychological-damage-heres-how-to-spot-the-
    signs-and-move-on-100288 [https://perma.cc/JY5C-9976] (discussing
    studies that outline effects of bullying including self-esteem issues and
    anger due to repeated victimization). The State’s expert drives by these
    very important developmental clues and finds nothing, individually or
    cumulatively, in Majors’ background to support lessened culpability?
    In addition, the State’s expert failed to recognize obvious features of
    the record that show immaturity, such as compromised capacity to
    52
    consider future consequences. When Majors was at Oakdale receiving
    psychiatric treatment, he was preoccupied, if not obsessed, with the notion
    that he threw his life away. Obviously, Majors came to the view that his
    risk-taking calculus was unbalanced. One of the trademark features of
    youth is undervaluing the long-term costs of their behavior to themselves
    and others.         See Laurence Steinberg & Elizabeth Scott, Less Guilty by
    Reason        of     Adolescence:    Developmental    Immaturity,    Diminished
    Responsibility, and the Juvenile Death Penalty, 58 Am. Psychologist 1009,
    1012 (2003). Majors stewing over his predicament suggests he came to
    recognize his “transient rashness, proclivity for risk, and inability to assess
    consequences” that Miller finds lessen culpability in 
    juveniles. 567 U.S. at 472
    , 132 S. Ct. at 2465.
    One of the elements of youthful immaturity is the influence of mass
    media. See generally Jeffery Jensen Arnett, Adolescents’ Use of Media for
    Self-Socialization, 24 J. Youth & Adolescents 519, 520 (1995) (finding
    media to be a significant part of adolescents’ lives, and the potential of
    media in socialization of youth “especially strong”); Jonathan Seiden,
    Comment, Scream-ing for a Solution: Regulating Hollywood Violence; An
    Analysis of Legal and Legislative Remedies, 3 J. Const. L. 1010, 1010
    (2001) (analyzing violence in film and the effects of viewing violent films on
    juveniles).        As noted by prestigious authority, the “visible and volatile”
    influence of media is an important part of the socio-ecology of children and
    youth.   Nat’l Res. Council & Inst. of Med., Studying Media Effects on
    Children and Youth 1 (2006).
    Majors is a poster child of the influence of the media. He got the
    idea of putting a plastic bottle on the end of his rifle to muffle the sound
    from a Steven Segal movie. Sounds like a pretty immature reaction to me.
    Copycat behaviors among juveniles who commit violent crime is not
    53
    unusual.       See Ray Surette, Self-Reported Copycat Crime Among a
    Population of Serious and Violent Juvenile Offenders, 48 Crime &
    Delinquency 46, 62 (2002).
    And then there is the issue of adolescent drug use.              Generally,
    adolescent drug usage has been found to be a mitigating factor to be
    considered in sentencing juvenile offenders. See, e.g., 
    Seats, 865 N.W.2d at 556
    (“One of the circumstances the sentencing judge needs to consider
    is whether substance abuse played a role in the juvenile’s commission of
    the crime.”). It certainly should have been considered here.
    At the time of resentencing, the State’s expert diagnosed Majors as
    having alcohol-use disorder, cannabis-use disorder, and stimulant
    disorder, specifically methamphetamine, all moderate and in sustained
    remission. These disorders must have predated his imprisonment and
    been developed as a juvenile. The record supports such a conclusion of
    adolescent polysubstance abuse by Majors. Any reasonable exploration of
    juvenile substance abuse would have yielded important information
    relevant to Majors’ sentence.
    The starting point is the accepted definition of substance-use
    disorder. 11    According to the DSM-5, substance-use disorder is
    characterized by a “cluster of cognitive, behavioral, and physiological
    symptoms indicating that the individual continues using the substance
    despite significant substance related problems.” Am. Psychiatric Ass’n,
    Diagnostic and Statistical Manual of Mental Disorders 483 (5th ed. 2013)
    [hereinafter DSM-5].
    Adolescent substance use is associated with negative health and
    behavioral outcomes, including alterations in neurodevelopment.                See
    11Under  the DSM-IV framework, which Majors was diagnosed under, the various
    alcohol- and substance-abuse disorders have been consolidated under the umbrella of
    substance-use disorder in the DSM-5.

    with negative health, social, and behavioral outcomes, including

    adolescence, exposure to neurotoxins, such as alcohol and illicit drugs,
    may interrupt neurodevelopment and associated cognitive and behavioral
    functioning.

    An important characteristic of substance-use disorder is the “underlying
    change in brain circuits that may persist beyond detoxification,” especially
    in individuals with severe disorders. DSM-5 at 483.
    Adolescent substance use has been linked to issues in interpersonal
    relationships. Studies report that temperamental and personality traits
    reflecting “behavioral undercontrol and poor self-regulation are associated
    with adolescent substance use problems.”           Laurie Chassin et al.,
    Adolescent Substance Use, in Handbook of Adolescent Psychology 676
    (Richard M. Lerner & Laurence Steinberg eds., 2d ed. 2004).             The
    personality characteristics most consistently associated with adolescent
    substance use include “unconventionality, low ego control, sensation
    seeking, aggression, impulsivity, and an inability to delay gratification.”
    
    Id. Additionally, adolescents
      with   substance   use   problems   are
    characterized by
    lower levels of executive functioning—that is, higher order
    cognitive processes that allows for future goal-oriented
    behavior. These processes include planning, organizational
    skills, selective attention, hypothesis generations, cognitive
    flexibility, maintenance of cognitive-set decision making,
    judgment, inhibitory control, and self regulation.

    Compared to adults, the health and social consequences of
    substance abuse for adolescents are more serious due to a variety of
    biological reasons.   Garrett O’Connor, The Psychology of Adolescent
    Addiction, 31 Val. U. L. Rev. 701, 701 (1997).
    While   experimentation     with   substances   occurs   for   many
    adolescents, some progress to regular use where the adolescent uses in an
    attempt to achieve a high or intoxication or they use as a coping
    mechanism.    
    Id. at 707.
       This may lead to a change in behavior from
    decreased school or job performance, social isolation, and deceitful
    patterns of behavior with family and friends to prevent them from learning
    about the drug use.    
    Id. Other behaviors
    include lying, stealing, and
    blaming others. 
    Id. at 707–08.
    In the event the adolescent continues using
    and their use becomes more frequent, more serious problems develop,
    including progression in severity of delinquent behaviors, an increase in
    depression, and reduced impulse control. 
    Id. Where other
    substances, such as alcohol, may require repeated uses
    and exposure to cause damage to the brain, methamphetamine can induce

    82 N.D. L

    symptoms, such as headaches, to accompany the psychological.

    Following         continued   use,    someone         who     is   addicted    to
    methamphetamine may “fly into a rage and act aggressively or violently”
    and   may       demonstrate     “increase[ed]       irritability,   impatience,     and
    impulsiveness,” thereby impairing the user’s relationships with those
    around them. 
    Id. at 1140.
    It may also produce “profound insomnia” in
    the user, though they are “not distressed by it, [as] he does not feel a need
    for sleep.   He feels highly productive, important, and intelligent.                He
    commonly does not realize he’s impatient. Instead, he places the blame
    on others . . . .” 
    Id. at 1139–40.
    Not surprisingly, “[methamphetamine] use during adolescence is
    associated with . . . behavioral problems such as increased anti-social
    behaviors.” Jordan M. Buck & Jessica A. Siegel, The Effects of Adolescent
    Methamphetamine Exposure, 9 Frontiers in Neuroscience 1, 2 (2015).
    Additionally,      in      adolescent      users,      methamphetamine-induced
    psychological and behavioral alterations appear to remain even after
    secession of the drug. 
    Id. The State’s
    expert sailed by these substance-abuse issues.
    Although polysubstance abuse was noted, it was simply not explored. In
    light of the history of parental abuse, the school transfer issue, the
    scoliosis, the mockery from childhood peers, the influence of the mass
    media, the polysubstance abuse, and the pent-up anger in Majors, there
    was a lot of material for a well-qualified child developmental psychologist
    or psychiatrist to consider.        But the State’s expert left these boulders
    unturned. In light of the gaps, the district court must determine whether
    the State successfully rebutted the notion that, “first and foremost,” a
    juvenile offender has less culpability than an adult. The professional
    opinion was not a meaningful evaluation utilizing child developmental
    psychology. There is no indication that the district court evaluated the
    57
    very weak nature of the expert testimony against the “first and foremost”
    and “children are different” framework. Where it is uncertain whether the
    correct legal standard has been applied, we may reverse and remand for
    application of the correct legal standard. 
    Showens, 845 N.W.2d at 449
    .
    E. Flawed Analysis of Ability to Navigate Legal System. The
    expert’s review of Majors’ medical records from 2003, finding that Majors
    was competent to stand trial and that he was not insane, led the expert to
    conclude that the Miller factor related to the ability of youth to interact
    with the legal system was not in play. But that reasoning is demonstrably
    incorrect. If Majors was incompetent or insane, there would be no trial,
    no conviction, and no sentence. See State v. Edwards, 
    507 N.W.2d 393
    ,
    395 (Iowa 1993) (“Constitutionally, defendants may not be tried or
    convicted while they are incompetent to stand trial or to assist in their
    defense.”); State v. McMullin, 
    421 N.W.2d 517
    , 518 (Iowa 1988) (“Insanity
    is an affirmative defense which, if proved, will preclude conviction of a
    crime.”). In other words, if he was insane or incompetent, there would be
    no need to consider Miller factors at all. If you use incompetence to stand
    trial and insanity as screening tools, you totally eliminate the criterion of
    difficulties juveniles face in navigating the court system as spelled out by
    the Supreme Court in Graham, and in our caselaw. The analysis offered
    by the expert is certainly, unquestionably, incorrect as a matter of law.
    Indeed, the State’s expert did not address the concerns of Graham.
    In Graham, the Court noted that youth have a limited understanding of
    the criminal legal system, “are less likely than adults to work effectively
    with their lawyers to aid in their defense” due to a lack of trust and more
    “limited understandings of the criminal justice system and the roles of the
    institutional actors within 
    it.” 560 U.S. at 78
    , 130 S. Ct. at 2032. When
    the question is appropriately framed, there is ample reason to believe that
    58
    Majors did, in fact, have trouble navigating the legal system, precisely as
    Graham forewarned.
    The State’s expert clearly did not review the record in this case. If
    she had, she would have learned that there was ample reason to believe
    that Majors had trouble dealing appropriately with the legal system. Over
    the course of the proceedings stemming from these charges, from 2002 to
    the present, Majors had at least eleven attorneys of record, many of which
    fairly quickly withdrew. Focusing on the relevant period of 2002–2003,
    Majors was represented by at least four attorneys. On May 31, 2002, a
    lawyer was appointed as counsel for Majors.                  That lawyer withdrew,
    however, on June 4, at which point a second lawyer appeared.                          On
    February 25, 2003, a third lawyer perfected the defendant’s appeal, which
    was handled by the state appellate defender’s office. On remand, a fourth
    lawyer undertook his representation, but withdrew on April 15.                       The
    musical chairs with all the lawyers, at the very least, suggests Majors had
    difficulty getting along with his legal representatives.
    Ultimately, Majors agreed to plead guilty to one count of attempted
    murder with the proviso that no appeal would be taken. 12 He then turned
    around and filed a notice of appeal, pulling down his plea bargain. He
    claimed that he did so because his parents and his attorney pressured him
    to accept the original plea bargain and that his attorney later urged him
    to appeal. After the appeal was filed, the original plea bargain failed and
    Majors was back to square one. Eventually, he plead guilty not only to
    12The condition of the plea bargain that no appeal be taken was very important to
    the State. There was little in the trial information to suggest that Majors attempted to
    murder anyone. No shots were fired. He hid in a closet, with duct tape, suggesting
    perhaps a planned kidnapping or sexual assault but something other than attempted
    murder. Although his rifle was loaded and he had clear shots at the victims, he did not
    discharge the weapon. In the plea colloquy, Majors generally admitted the facts in the
    trial information, but examination of the minutes do not clearly establish the basis for
    attempted murder.
    59
    attempted murder, which was the sole crime for which he was convicted
    in the first plea bargain, but the additional crime of burglary. Because of
    his on-off-on approach to the plea bargain, Majors ended up with an
    additional ten years added onto his prison sentence. Inability to navigate
    the legal system abounds in this example.
    The State’s expert noted that Majors tried to manipulate the system
    by feigning psychiatric illness pending disposition of criminal charges. To
    the extent this is true, such a manipulative maneuver is part of the normal
    adolescent effort to avoid responsibility but also shows a fundamental
    misunderstanding of how our legal system works.
    Further, as correctly narrated by the State’s expert, Majors came up
    with numerous oddball and inconsistent stories attempting to explain his
    behavior. No doubt he attempted to manipulate the legal system to lessen
    his culpability, and those attempts failed.      It seems likely that his
    immaturity led him to make these inconsistent stories and failed efforts to
    manipulate the legal system. As every parent knows, nonacceptance of
    blame and inconsistent reporting is a trademark feature of youth called to
    account for their actions.
    Finally, as with the age criterion, the expert shifted the burden of
    proof on the question of the ability of juvenile defendants to navigate the
    court system. When asked whether Majors was able to understand the
    legal proceedings, the expert noted that they “don’t have any evidence to
    the contrary.” But evidence to the contrary is exactly what is required to
    eliminate difficulties in navigating the court system as a mitigating factor
    when considering imposition of an adult mandatory sentence on a juvenile
    offender.
    The district court did not focus on the potential difficulties Majors
    had in navigating the legal system. The district court did emphasize that
    60
    Majors backed out of a plea agreement, ultimately resulting in an
    additional ten-year sentence. If this case were to be remanded, the district
    court would have an opportunity to give the question more careful
    consideration.
    F. Flawed Approach to Impulsivity. The State’s expert suggested
    that because Majors engaged in planning for his crime, Majors lacked the
    impulsivity associated with youth. There is no exact and unique definition
    of impulsivity, and there is no agreement over its major components.
    Nour-Mohammad Bakhshani, Impulsivity: A Predisposition Toward Risky
    Behaviors, 3 Int’l J. High Risk Behavs. & Addiction 1, 3 (2014). Impulsivity
    has sometimes been defined as swift action without forethought or
    conscious judgment, but also as “behavior without adequate thought” and
    “the tendency to act with less forethought than do most individuals of
    equal ability and knowledge.” F. Gerard Moeller et al., Psychiatric Aspects
    of Impulsivity, 158 Am. J. of Psychiatry 1783, 1783 (2001).
    But under the caselaw, it is clear that the latter two definitions of
    impulsivity apply when considering the mitigating features of youth. For
    example, in Johnson v. Texas, 
    509 U.S. 350
    , 
    113 S. Ct. 2658
    (1993), the
    Supreme Court considered a case where the nineteen-year-old defendant
    surveyed the layout of the store prior to a robbery, determined the number
    of workers present, determined to kill any witnesses to the crime, retrieved
    a handgun, engaged in robbery, and killed an employee. 
    Id. at 353,
    113
    S. Ct. at 2661. The Court noted that the jury was entitled to consider the
    mitigating qualities of youth which “often result in impetuous and ill-
    considered actions and decisions.”       
    Id. at 367,
    113 S. Ct. at 2669.
    Similarly, in Roper, a seventeen-year-old defendant planned to commit a
    burglary and murder by breaking and entering, tying up a victim, and
    throwing her from a bridge into the 
    water. 543 U.S. at 556
    –57, 
    125 S. Ct. 61
    at 1187–88. Counsel challenging his sentence called clinical psychologists
    and other witnesses indicating that the defendant was “very immature,”
    and “very impulsive.” 
    Id. at 559,
    125 S. Ct. at 1189. In granting relief, the
    Roper Court cited Johnson for the proposition that juveniles engage in
    “impetuous and ill-considered actions.” Id. at 
    569, 125 S. Ct. at 1195
    (quoting 
    Johnson, 509 U.S. at 367
    , 113 S Ct. at 2669).          Likewise, in
    Graham, the juvenile defendant engaged in a crime spree which showed
    planning, yet the Court again in granting relief cited Johnson, noting that
    the qualities of youth included a tendency to make “impetuous and ill-
    considered actions and 
    decisions.” 560 U.S. at 72
    , 130 S. Ct. at 2028
    (quoting Johnson, 509 U.S. at 
    367, 113 S. Ct. at 2669
    ).
    Clearly, under Johnson, Roper, and Graham, the fact that the
    underlying crime involved planning does not negate the notion that the
    signature qualities of youth, including the tendency to make “impetuous
    and ill-considered decisions,” may be considered as a mitigating factor in
    the sentencing of a juvenile offender.     And, as noted by Roby, “[t]he
    aggravating circumstances of a crime that suggest that an adult offender
    is depraved may only reveal a juvenile offender to be wildly immature and
    
    impetuous.” 897 N.W.2d at 146
    . The fact that juveniles have the ability
    to plan a crime does not negate the proposition that “children are different”
    or the application of Roper-Graham-Miller principles. To the extent the
    district court relied on “planning of the crime” as preventing application of
    the mitigating features of youth, it applied the wrong legal standard.
    G. Treatment of Rehabilitation. Developmental psychology tells
    us two things about the prospects for the rehabilitation of juveniles and
    our ability to predict which offenders will commit violence in the future.
    First, rehabilitation is the norm for juvenile offenders, even when they
    commit heinous crimes. The origins of the juvenile justice system are
    62
    rooted in the idea of more rehabilitation for youthful offenders than their
    adult counterparts. See 
    Lyle, 854 N.W.2d at 390
    –92 (summarizing the
    social science and caselaw underlying the rehabilitative purposes inherent
    in juvenile justice); Comm. on Assessing Juvenile Justice Reform, Nat’l
    Acad. of Scis., Reforming Juvenile Justice 1–4, 31–49 (2013) [hereinafter
    Nat’l Acad. of Scis., Reforming Juvenile Justice] (outlining the penological
    differences in dealing with juvenile and adult offenders); Martin Gardner,
    Youthful Offenders and the Eighth Amendment Right to Rehabilitation:
    Limitations on the Punishment of Juveniles, 
    83 Tenn. L
    . Rev. 455, 471–74
    (2016) (expounding on the rehabilitative origins of the juvenile justice
    framework); Kathryn Monahan et al., Juvenile Justice Policy and Practice:
    A Developmental Perspective, 44 Crime & Just. 577, 577 (2015)
    [hereinafter Monahan et al., A Developmental Perspective] (“The early
    juvenile court viewed and treated juveniles as distinct from adults, with a
    greater focus on rehabilitation as opposed to punishment for youthful
    criminal behavior.”).
    In fact, a developmental approach recognizes that the illegal
    behavior occurred during a period of development when youth are more
    likely to exercise poor judgment and engage in risky behavior in pursuit of
    thrills and excitement. Nat’l Acad. of Scis., Reforming Juvenile Justice at
    20 (“A developmental approach to juvenile justice recognizes that illegal
    acts committed by adolescents occur in the context of a distinct period of
    human development, a time of life when individuals are more likely to
    exercise poor judgment, take risks, and pursue thrills and excitement.”).
    Research reinforces that juveniles are different from adults in their
    cognitive processing and development, making them categorically
    different. 
    Id. at 32
    (“[A] growing body of research [over the last decade] on
    adolescent development, particularly brain development . . . reinforces the
    63
    conventional wisdom that adolescents are different from adults in ways
    that affect their criminal conduct, and it has probably contributed to the
    reemergence of less punitive attitudes toward juvenile offenders.”). While
    the pendulum has swung between orientations of punishment versus
    rehabilitation, it has shifted back through the use of developmental
    sciences. Monahan et al., A Developmental Perspective, 44 Crime & Just.
    at 578 (noting that declining crime rates, increasing support for
    rehabilitative   penological    approaches,     and     advancing     scientific
    understanding of developmental science contribute to this shift). This was
    best captured in Roper, where the Court recognized the “diminished
    culpability of juveniles” and their greater capacity for rehabilitation due to
    their “transient 
    immaturity.” 543 U.S. at 571
    , 
    573, 125 S. Ct. at 1196
    –
    97. This principle was applied in subsequent cases regarding juvenile
    culpability in both the United States Supreme Court and this court. See
    
    Miller, 567 U.S. at 471
    , 132 S. Ct. at 2464; 
    Graham, 560 U.S. at 68
    , 130
    S. Ct. at 2026; 
    Lyle, 854 N.W.2d at 392
    .
    Second, while some offenders may well reoffend in the future, it is
    extremely difficult, if not impossible, to make predictions of future
    dangerousness.     See, e.g., Erica Beecher-Monas, The Epistemology of
    Prediction: Future Dangerousness Testimony and Intellectual Due Process,
    60 Wash. & Lee L. Rev. 353, 362–63 (2003) (suggesting that clinical
    predictions about future dangerousness are too unreliable for use in
    court); Adam Lamparello, Using Cognitive Neuroscience to Predict Future
    Dangerousness, 42 Colum. Hum. Rts. L. Rev. 481, 488 (2011) (“[T]he
    courts––and commentators––have consistently recognized that predictive
    adjudications, whether it be for future dangerousness or lack of control,
    are often unreliable or . . . simply inaccurate.”). In fact, the likelihood of a
    juvenile offender become a chronic adult criminal is small.            Alex R.

    Policy Regarding Developmental/Life-Course Criminology, 39 New Eng. J.
    on Crim. & Civ. Confinement 347, 353 (2013) [hereinafter Piquero, Youth
    Matters] (“Only a very small number of persons continue to offend into and
    throughout adulthood . . . .”).
    Rates of all kinds of crimes committed by juveniles decrease
    precipitously with age, a phenomenon referred to as the “age-crime curve.”

    Decisions About Adolescents’ Criminal Culpability, 14 Nature Reviews
    Neuroscience 513, 515 & fig. 1 (2013) (illustrating “a consistent

    in the overall crime rate); see also Alex R. Piquero et al., Violence in
    Criminal Careers: A Review of the Literature from a Developmental Life-
    Course Perspective, 17 Aggression & Violent Behav. 171, 172 (2012)
    (examining theoretical frameworks for longitudinal offending patterns).
    Further, across many studies, it appears that even for violent offenders,
    “the likelihood of repeating [violence] is very rare.” Piquero, Youth Matters,
    39 New Eng. J. on Crim. & Civ. Confinement at 356. These difficulties are
    even more present when juvenile offenders are involved. See 
    Roper, 543 U.S. at 573
    , 125 S. Ct. at 1197 (“It is difficult even for expert psychologists
    to differentiate between the juvenile offender whose crime reflects
    unfortunate yet transient immaturity, and the rare juvenile offender whose
    crime reflects irreparable corruption.”); Larson et al., Mental Health
    Assessments, 39 New Eng. J. on Crim. & Civ. Confinement at 335–36
    (“[T]here is currently no basis in current behavioral science nor well-
    informed professional knowledge that can support any reliable forensic
    expert opinion on the relative likelihood of a specific adolescent’s prospects
    for rehabilitation at a date that may be years to decades in the future.”);

    et al., Juvenile Sentencing Reform, 88 Temp. L. Rev. at 684 (“[P]rediction of
    future violence from adolescent criminal behavior, even serious criminal
    behavior, is unreliable and prone to error.”).
    In Roby, we stated that rehabilitation was a factor that supports
    mitigation for most juvenile offenders because “delinquency is normally
    
    transient.” 897 N.W.2d at 147
    .       We emphasized that “judges cannot
    necessarily use the seriousness of a criminal act, such as murder, to
    conclude the juvenile falls within the minority of juveniles who will be
    future offenders or are not amenable to reform.”           
    Id. After all,
    “the
    signature qualities of youth are transient.”        
    Lyle, 854 N.W.2d at 394
    (quoting 
    Roper, 543 U.S. at 570
    , 125 S. Ct. at 1196). We have further
    concluded, however, that in the resentencing of juveniles, current evidence
    regarding rehabilitation is admissible. State v. Ragland, 
    836 N.W.2d 107
    ,
    121–22 (Iowa 2013) (finding that individualized sentencing considerations,
    including demonstrated maturity and rehabilitation, must necessarily be
    meaningfully considered in juvenile sentencing).
    While rehabilitation is thus the norm, it is extremely difficult to
    predict future dangerousness of adults and even harder with respect to
    juveniles. The inability to identify irreparably corrupt juveniles led the
    United States Supreme Court to categorical rules in Graham and Roper.
    Here, Majors has been incarcerated for most of his prison stay in a
    maximum security prison.           Because of the shortage of available
    programing and the length of his sentence, he has been waitlisted for
    victim-impact programming.        Juveniles serving lengthy sentences are
    often disadvantaged in prison by lack of services to meet their
    66
    developmental needs.     Some prisons can be “complicit in the lack of
    development” because “it is the policy in some prisons to withhold
    counseling, education, and rehabilitation programs for those who are
    ineligible for parole consideration.” 
    Graham, 560 U.S. at 79
    , 130 S. Ct. at
    2032–33. Majors is no exception.
    Majors had a lengthy disciplinary record while in prison related to
    drug offenses and other nonviolent offenses. In 2014, six of Majors’ eight
    offenses were drug or alcohol related; in 2013 all four of his offenses were
    drug or alcohol related. In 2012, four out of ten were drug or alcohol
    related; in 2010 he had one offense for not wearing his identification; and
    a few years he had some verbal or possession related offenses. Research
    suggests that there are many causes of prison disciplinary problems. See
    generally David DeMatteo et al., The Use of Measures of Psychopathy in
    Violence Risk Assessment, in Handbook of Violence Risk Assessment 19–
    40 (Randy S. Otto & Kevin S. Douglas eds., 2010). Additionally, studies
    show age, education, and social supports can contribute to misconduct.
    Alan J. Drury & Matt DeLisi, The Past Is Prologue: Prior Adjustment to
    Prison and Institutional Misconduct, 90 Prison J. 331, 333 (2010) (noting
    studies that indicate “inmates who are younger, male, less educated, lack
    a social support network . . . and/or have a history of violent behavior
    engage in significantly higher levels of misconduct in prison than inmates
    not possessing these characteristics”).
    A lengthy prison sentence gives little hope and little incentive to
    reform; but once it became possible that he might be able to challenge the
    mandatory minimum sentence, Majors’ behavior, consistent with renewed
    hope, turned around. Majors now has not had any discipline in the four
    years prior to the hearing in this case. Even the expert stated that the last
    four years evinced Majors had “the capacity for change.”
    67
    In 2013, Judge Ann Power-Forde, sitting as a member of the Grand
    Chamber of the European Courts of Human Rights, summed up the
    importance of the prospect of release for someone incarcerated, stating
    that
    hope is an important and constitutive aspect of the human
    person. Those who commit the most abhorrent and egregious
    of acts and who inflict untold suffering upon others,
    nevertheless retain their fundamental humanity and carry
    within themselves the capacity to change. Long and deserved
    though their prison sentences may be, they retain the right to
    hope that, someday, they may have atoned for the wrongs
    which they have committed. They ought not to be deprived
    entirely of such hope. To deny them the experience of hope
    would be to deny a fundamental aspect of their humanity and,
    to do that, would be degrading.
    Vinter & Others v. United Kingdom, [2013] Eur. Ct. H.R. 645 (July 9, 2013),
    http://www.bailii.org/eu/cases/ECHR/2013/645.html.          In Graham, the
    emphasis on rehabilitation was renewed.           See Chad Flanders, The
    Supreme Court and the Rehabilitative Ideal, 
    49 Ga. L
    . Rev. 383, 413 (2015)
    [hereinafter Flanders, Rehabilitative Ideal] (“Indeed, the fact that life in
    prison without parole foreclosed ‘the rehabilitative ideal’ (as the Court put
    it) is central to its holding. . . . [and] is perhaps the theme of the opinion
    . . . .” (Footnote omitted.)).   With rehabilitation comes hope.      Justice
    Kennedy stated the proposition succinctly when he wrote that “[l]ife in
    prison without the possibility of parole gives no chance for fulfillment
    outside prison walls, no chance for reconciliation with society, [and] no
    hope.” 
    Graham, 560 U.S. at 79
    , 130 S. Ct. at 2032.
    Tailoring rehabilitation to the individual can be “both backward-
    looking and retributive or forward-looking and rehabilitative.” Flanders,
    Rehabilitative Ideal, 
    49 Ga. L
    . Rev. at 394. The difference, simply defined,
    is that
    68
    [i]f the judge is looking at details about the offender . . . to find
    out what he deserves as his punishment, then the judge’s
    individualizing is backward-looking: he is trying to fit the
    offender to the right amount of deserved retributive
    punishment. . . .
    But if the judge is using those same details to determine
    how much rehabilitation the offender needs––as well as his
    fitness for rehabilitation––the judge’s individualizing is
    forward-looking.
    
    Id. Further, there
    appears to be a life cycle of prison disciplinary events
    for juvenile offenders.     During early years of incarceration, juvenile
    offenders often engage in a higher base rate of misconduct with a reduction
    as they mature. Larson et al., Mental Health Assessments, 39 New Eng.
    J. on Crim. & Civ. Confinement at 341 (“We know that even chronic and
    violent juvenile offenders are more likely to desist from such behaviors
    than continue them into adulthood.”). And, it is hardly surprising that
    Majors, who has a history of untreated polysubstance abuse, has several
    disciplinary violations related to drug and alcohol abuse in light of the
    inability of the department of corrections to provide him with substance-
    abuse programming.
    Among other things, the literature establishes that youthful
    offenders are more likely to be victims of both physical nonsexual and
    sexual crime and property crime. 
    Id. at 337
    nn.75–76 (providing statistics
    on crimes against incarcerated juveniles). Majors was a victim of sexual
    assault while incarcerated. Such victimization increases the likelihood of
    disciplinary history.
    In any event, on the question of future rehabilitation, predictions are
    often quite difficult. We should be extremely cautious of unstructured
    clinical evaluations by a psychologist unfamiliar with the principles of
    child developmental psychology.
    69
    Further, there is the issue of consistency. Judges necessarily make
    an ad hoc judgment, case by case, but the parole board is in a better
    position to ensure consistency. While the district court’s characterization
    of the rehabilitation as minimally        favorable is, if anything, an
    understatement, it is unclear whether the district court regarded
    rehabilitation as the norm under a “first and foremost” and “children are
    different” framework. As a result, reversal and remand is appropriate.
    
    Showens, 845 N.W.2d at 449
    –50.
    H. Lack of Remorse as a Juvenile Trait. One of the signature
    features of youth is thoughtlessness toward others. “Adolescents, often
    thoughtless and impulsive, will perpetrate a crime . . . without considering
    its impact on others.” David E. Arredondo, Child Development, Children’s
    Mental Health and the Juvenile Justice System: Principles for Effective
    Decision-Making, 14 Stan. L. & Pol’y Rev. 13, 21 (2003). Compared to
    adults,   the   characteristics   underlying   remorselessness,   such   as
    egocentrism and lack of empathy, do not have the same predictive
    importance for future behaviors because the traits are so common in
    adolescent development.      Adam Saper, Juvenile Remorselessness: An
    Unconstitutional Sentencing Consideration, 38 N.Y.U. Rev. L. & Soc.
    Change 99, 137 (2014) [hereinafter Saper, Juvenile Remorselessness]
    (“Sociological pressures limit a youth’s expression of remorse . . . [and]
    these expressions are hindered by developmental limitations ranging from
    an inability to fully appreciate the sensation of remorse, to inadvertent
    pain avoidance techniques that result in the suppression of otherwise
    existing emotions.”).
    And, as noted in Graham, “[t]he juvenile should not be deprived of
    the opportunity to achieve maturity of judgment and self-recognition of
    human worth and potential. . . . Maturity can lead to that considered
    70
    reflection   which   is   the   foundation   for   remorse,    renewal,   and
    rehabilitation.” 560 U.S. at 
    79, 130 S. Ct. at 2032
    (emphasis added). And
    in the words of Roper, youth have an “underdeveloped sense of
    responsibility.” 543 U.S. at 
    569, 125 S. Ct. at 1195
    . In other words, seen
    through the lens of child development as applied in Graham and Roper, a
    juvenile’s lack of remorse is not the equivalent of a lack of remorse in fully
    developed adults.    It is part of youthful immaturity, and therefore a
    mitigating factor, not an aggravating factor, in sentencing.
    Further, even to the extent relevant, remorselessness cannot be
    assessed in a clinical interview. Indeed, as a youth, the record reveals that
    Majors had trouble communicating in group, tended to keep to himself,
    and not volunteer. According to the DSM-5, psychologists should only
    conclude that an individual lacks remorse by looking at
    multiple information sources. . . . In addition to the
    individual’s self-report, it is necessary to consider reports by
    others who have known the individual for extended periods of
    time [and across relationships and settings] (e.g., parents,
    teachers, co-workers, extended family members, peers).
    DSM-5 at 470. No evidence in this case was offered to comply with the
    DSM-5 requirement.
    At the most recent hearing, Majors, now in his mid-thirties,
    apologized to the victims. He asked the court for permission to address
    them, but that was denied. Majors proceeded to take full responsibility for
    his actions and apologized, saying “I would just like to apologize. I couldn’t
    imagine anybody running into my house and pointing a gun at my mom,
    couldn’t imagine what the Peckhams went through. I’m sorry for it.”
    In short, lack of remorse is a transient juvenile trait that is often
    ameliorated as the juvenile matures. Those in charge of sentencing must
    not apply adult standards of remorse to juveniles; if they do, they fail to
    71
    recognize that children are different from adults in terms of their emotional
    and social development. See Stephanos Bibas & Richard A. Bierschbach,
    Integrating Remorse and Apology into Criminal Procedure, 114 Yale L.J. 85,
    94 (2004) (“Seemingly remorseless acts by children or adolescents can
    affect whether they are tried as juveniles or as adults.”); Kristin Henning,
    Criminalizing Normal Adolescent Behavior in Communities of Color: The Role
    of Prosecutors in Juvenile Justice Reform, 98 Cornell L. Rev. 383, 440–41
    (2013) (noting that factors such as language skills, limited life experiences,
    diminished capacity, peer pressure, teenage bravado, and implementation
    of coping mechanisms—humor, denial, or indifference—make remorse “a
    particularly unreliable measure of a youth’s amenability to treatment and
    need for punishment”); Lauren M. Kelly, Admit the Crime or Do the Time:
    Pennsylvania’s Juvenile Transfer Conundrum, 73 U. Pitt. L. Rev. 563, 579
    (2012) (noting that paradoxically “[b]y requiring the juvenile to take
    responsibility for his action and show remorse,” that “the juvenile is
    implicitly required to admit guilt”). See generally Martha Grace Duncan,
    “So Young and So Untender”: Remorseless Children and the Expectations of
    the Law, 102 Colum. L. Rev. 1469 (2002) (exploring the inability of courts
    to correctly adjudge remorse in juveniles, and questioning the validity of
    remorsefulness in predicting recidivism and rehabilitation); Saper,
    Juvenile Remorselessness, 38 N.Y.U. Rev. L. & Soc. Change at 99 (framing
    consideration of remorselessness in the sentencing of juveniles as
    unconstitutional due to key developmental differences in youth and adults
    regarding remorse, and the propensity of courts to mistake hallmarks of
    juvenile developmental immaturity as dispositive of remorselessness). The
    district court does not appear to have utilized a “first and foremost” and
    “children are different” framework in evaluating the lack of remorse.
    Again, “[p]erceptions applicable to adult behavior cannot normally be used
    72
    to draw conclusions from juvenile behavior.” 
    Roby, 897 N.W.2d at 147
    .
    On the remorse issue, Majors erroneously was treated like an adult by the
    district court.
    I. A Note on Discretion. We have indicated that the review of a
    district court sentence applying Miller factors is for abuse of discretion.13
    But this does not mean the discretion is freestanding and without bounds.
    Indeed, while an element of discretion may be involved, that discretion
    may only be exercised when the state makes a compelling case that the
    Miller factors defeat the ordinary presumption against imposition of the
    mandatory minimums for juvenile offenders.                   The discretion must be
    exercised in a fashion that recognizes that the ability of judges to predict
    which offenders will return to crime is quite limited 14 and that subjective
    decisions are not very useful and can lead to serious fairness concerns.
    Unbridled district court discretion would have several unacceptable
    consequences.         First, it would allow for a variable enforcement of
    constitutional rights. Second, it would further open the door to implicit
    bias that is already rampant in our criminal justice system. See Jeffrey
    Fagan, The Contradictions of Juvenile Crime & Punishment, Daedalus,
    Summer 2010, at 43, 51–52 (noting that “[r]acial disparities in juvenile
    detention and incarceration closely resemble racial disparities in the
    imprisonment and jailing of adults,” as well as providing statistics and
    analysis to that effect); Sandra Graham & Brian S. Lowery, Priming
    13Although   I joined the Roby decision in its entirety, upon reflection, I doubt that
    the abuse of discretion standard is the correct standard when constitutional claims are
    at stake. Constitutional claims must apply equally across all cases and should not be
    subject to variabilities in the exercise of judicial discretion.
    14For  instance, in an amicus brief filed in Miller, juvenile court judges explained
    that “the criminal justice system cannot predict what kind of person a fifteen-year-old
    juvenile offender will be when he is 35 or 55 or 75.” Brief of Former Juvenile Ct. Judges

    ,

    bias, and noting that “[e]ven decision makers with good intentions are
    susceptible”).
    J. Summary. Writing a few years ago, Scott et al., declared that
    “adhering to the Court’s developmental framework and limiting the impact
    of punitive impulses toward juvenile offenders generally poses an ongoing
    challenge.” Scott et al., Juvenile Sentencing Reform, 88 Temp. L. Rev. at
    714. They are certainly correct.
    Unfortunately, this case represents unprincipled backsliding.
    Stripped of the window dressing, the hearing in this case was the kind
    utilized, day in and day out, in the sentencing of adults. For the reasons
    stated above, the sentence in the case must be vacated and the case
    remanded for a new sentencing hearing.
    II. Ineffective Assistance of Counsel.
    A. Introduction. On appeal, Majors claims that his counsel was
    ineffective at his resentencing hearing. For reasons that completely escape
    me, criminal defense lawyers all too often regard sentencing hearings as
    requiring them only to review a presentence investigative (PSI) report for
    errors or mistakes and to present a smattering of argument to the judge
    prior to sentencing. See State v. Hill, 
    878 N.W.2d 269
    , 275–76 (Iowa 2016)
    (Appel, J., concurring specially) (noting the critical nature of sentencing
    within criminal proceedings and exploring the professional responsibilities
    of attorneys related to sentencing). In our current system, where plea
    bargaining is the norm, the sentencing proceeding is the most important
    part of a criminal proceeding.
    74
    There has been recognition in the literature that sentencing is given
    short shrift by the participants. As noted by one authority, “[s]entencing
    is too often considered an afterthought rather than seen as a critical stage
    in a criminal case.” Cait Clarke & James Neuhard, “From Day One”: Who’s
    in Control as Problem Solving and Client Centered Sentencing Takes Center
    Stage?, 29 N.Y.U. L. Rev. & Soc. Change 11, 12 (2004). As discussed
    below, the problem becomes more acute when dealing with a juvenile
    offender.
    B. Applicable Standards for Ineffective Assistance of Counsel.
    The American Bar Association’s Center for Criminal Justice states that
    counsel in a criminal case “has a duty independently to investigate the
    client’s circumstances, including such factors as previous history, family
    relations, economic condition, and any other information relevant to
    disposition.” Juvenile Justice Standards: Standards Relating to Counsel
    for Private Parties, standard 9.2(b)(ii), at 175 (Inst. Judicial Admin. & Am.
    Bar Ass’n 1980). Further, a defense lawyer “should present all arguments
    or evidence which will assist the court or its agents in reaching a
    sentencing disposition favorable to the accused” and should verify,
    supplement, or challenge information in any presentence report made
    available to the defense “rather than relying on the court’s presentence
    report.” Standards for Criminal Justice, standard 4-8.3(c), (e) (Am. Bar
    Ass’n 4th ed. 2015).
    A go-along-to-get-along philosophy does not comport with effective
    assistance for a criminal defendant. As stated in the ABA Standards for
    Criminal Justice: Prosecution Function and Defense Function 4-1.2(e), at
    120–21 (3d ed.1993),
    Advocacy is not for the timid, the meek, or the retiring. Our
    system of justice is inherently contentious, albeit bounded by
    the rules of professional ethics and decorum, and it demands
    75
    that the lawyer be inclined toward vigorous advocacy. Nor can
    a lawyer be half-hearted in the application of his or her
    energies to a case. Once a case has been undertaken, a lawyer
    is obliged not to omit any essential lawful and ethical step in
    the defense, without regard to compensation or the nature of
    the appointment. . . .
    Because the law is a learned profession, lawyers must take
    pains to guarantee that their training is adequate and their
    knowledge up-to-date in order to fulfill their duty as
    advocates.
    
    Id. cmt., at
    122–23 (footnote omitted); see also State v. Clay, 
    824 N.W.2d 488
    , 495–96 (Iowa 2012).
    It is not enough for counsel at sentencing to simply look over the PSI
    report, make a few corrections, and plead for mercy. Counsel must engage
    in thorough preparation, develop a sensible plan, and mount a vigorous
    mitigation defense. See generally Miriam S. Gohara, Grace Notes: A Case
    for Making Mitigation the Heart of Noncapital Sentencing, 41 Am. J. Crim.
    L. 41 (2013) (noting the success of well-prepared investigation and
    presentation of mitigating life history in legal proceedings). The need for
    zealous counsel is critical in cases involving juvenile sentencing. There
    can be a temptation, contrary to the teachings of Roper, Miller, Null, and
    Roby, to sentence juveniles harsher than adults on the ground that early
    onset of violent criminal activity shows a particularly depraved person.
    But a sentencing judge must be given the proper understanding of child
    developmental psychology before sentencing a juvenile offender to an adult
    sentence.
    Not surprisingly, Juvenile Justice Standards provide that “[t]he
    lawyer should seek to secure the assistance of psychiatric, psychological,
    medical or other expert personnel needed for purposes of evaluation,
    consultation or testimony with respect to formation of a disposition plan.”
    Juvenile Justice Standards: Standards Relating to Counsel for Private
    Parties, standard 9.2(c), at 177; see Barbara Fedders, Losing Hold of the
    76
    Guiding Hand: Ineffective Assistance of Counsel in Juvenile Delinquency
    Representations, 14 Lewis & Clark L. Rev. 771, 796 (2010) (noting the
    systematic failure of juvenile delinquency attorneys to gather necessary
    records or hire experts).    See generally Beth Caldwell, Appealing to
    Empathy: Counsel’s Obligation to Present Mitigating Evidence for Juveniles
    in Adult Court, 
    64 Me. L
    . Rev. 391 (2012) [hereinafter Caldwell, Appealing
    to Empathy] (discussing broadly the professional obligations of attorneys
    to present mitigating evidence and the impact such mitigation may have
    on case outcomes).
    Attorneys have a range of responsibilities unique to juvenile
    representation. By way of example,
    the National Juvenile Defender Center interprets the duties of
    competence and diligence to require that juvenile defense
    attorneys are “well-versed in the areas of child and adolescent
    development” and have a “working knowledge,” and contact
    with experts, in “collateral consequences” of conviction,
    special education, abuse and neglect, cultural competence,
    and mental health. In addition, these standards indicate that
    competent juvenile defense counsel should consult “with
    mitigation specialists, social workers, and mental health,
    special education, and other experts to develop a plan
    consistent with the client’s expressed interests” at the
    disposition hearing. Counsel should also “prepare[] and
    present[] the court with a creative, comprehensive, strengths-
    based, individualized disposition alternative consistent with
    the client’s expressed interests.” Although these standards
    relate to the representation of juveniles in delinquency court,
    they are germane to representing juvenile offenders in adult
    court.
    Caldwell, Appealing to Empathy, 
    64 Me. L
    . Rev. at 410–11 (quoting Robin
    Walker Sterling, Nat’l Juvenile Defs. Ctr., Role of Juvenile Defense Counsel
    in Delinquency Court 14, 18 (2009)).
    These standards are designed to apply in juvenile adjudications, but
    it is inconceivable to me that a lesser standard would apply in a criminal
    77
    sentencing proceeding involving a juvenile or in a resentencing hearing of
    a juvenile offender.
    C. Application of Standards. In light of these standards, a strong
    case can be made that Majors’ counsel was ineffective. In considering a
    resentencing of a juvenile offender, the fact finder must be introduced to
    the science of adolescent brain development in some fashion.           Such
    evidence may be received through an expert who testifies about what is
    known of adolescent brain development and its corresponding thought
    processes.   Jenny E. Carroll, The Problem with Inference and Juvenile
    Defendants, 45 Fla. St. U. L. Rev. 1, 49 (2017) (noting that “[s]uch
    testimony could occur in two forms: an expert could evaluate a particular
    defendant and testify as to her cognitive processes, or an expert could
    speak more broadly to what is generally known of adolescent brain
    development and its corresponding thought processes” (footnote omitted)).
    But Majors’ counsel took no steps to present the court with this kind
    of critical information.   He did not challenge the qualifications of the
    State’s expert and allowed the prosecutor to ask a long series of leading
    questions to his expert. His involvement with the generalized state expert
    was limited to cursory cross-examination of the State’s witnesses.
    For example, counsel for Majors did not meaningfully challenge the
    just-short-of-eighteen theory.   He did not confront the expert with the
    many authorities in child psychology to the contrary. And, counsel did
    not present the caselaw to the contrary to the district court.       Indeed,
    counsel did not provide a brief on sentencing.     None of the applicable
    caselaw was presented to the district court. Similarly, counsel did not
    explore the “first and foremost” dictates of Roby, either through cross-
    examination of the expert or in his nonexistent briefing before the court.
    78
    Counsel offered no evidence at the hearing other than a brief
    statement from the client.     There is certainly nothing in the record to
    suggest that counsel did any independent investigation of the long list of
    potentially mitigating leads which would have been revealed from a
    cursory review of the trial record.
    On appeal, the State asserts correctly that the record shows that
    Majors did not wish to have an independent medical examination and that
    he explicitly directed his lawyer not to pursue it. There are three problems
    here. First, an independent medical examination is not what he really
    needed. No one claimed he had a current medical condition that required
    diagnosis. Indeed, the State explicitly declined to claim, for instance, that
    Majors had any diagnosable disorder such as an antipersonality conduct
    disorder. What Majors’ counsel desperately needed, as is abundantly clear
    in this case, was a child development expert to explain to counsel the
    fundamentals     of   child   developmental   psychology,   assist   in   the
    development of the case, and offer testimony to support Majors’ position.
    Without such assistance, the counterintuitive principles of child
    development psychology were wholly unpresented and unexplored in this
    case.
    Second, the decision whether to call an expert witness is not
    generally a client decision but rests with effective counsel. See State v.
    Sammons, 
    749 P.2d 1372
    , 1377 (Ariz. 1988) (en banc) (finding the decision
    to call an expert witness “a matter of trial strategy” for counsel); Davis v.
    State, 
    723 S.E.2d 431
    , 434 (Ga. 2012) (stating that the decision to call
    experts is “within the broad range of professional conduct afforded trial
    attorneys”). Further, Majors’ expressed preference made no sense. First,
    there was plenty of time prior to the hearing for his counsel to hire a
    qualified child development psychologist. Second, if the record was later
    79
    supplemented, there was no significant possibility that this decision would
    have delayed his release.    He had not yet taken substance abuse and
    victim impact programming. There was little possibility that any delay
    caused by the hiring of a qualified expert witness would have significantly
    delayed his release from prison. Acquiescing in the client’s desire not to
    hire an expert was the easiest course, but it did not reflect zealous
    advocacy.
    It is also suggested that counsel made a strategic decision not to call
    an expert because he elicited the testimony he needed from the State’s
    expert. But in light of the completely inadequate testimony obtained from
    the State’s expert, this conclusion simply cannot be sustained. Counsel
    for Majors seems to have been unaware of the child developmental science
    and the applicable Iowa caselaw. It is difficult to understand the strategic
    reasoning behind not hiring a qualified expert to prevent the risk of a
    runaway train based upon unqualified expert opinion.
    In addition to the question of duty, there is the question of prejudice.
    In order to find prejudice, our confidence in the outcome must be
    undermined. Strickland v. Washington, 
    466 U.S. 668
    , 694, 
    104 S. Ct. 2052
    , 2068 (1984) (“The defendant must show that there is a reasonable
    probability that, but for counsel’s unprofessional errors, the result of the
    proceeding would have been different . . . [which is] sufficient to undermine
    confidence in the outcome.”); Ledezma v. State, 
    626 N.W.2d 134
    , 143 (Iowa
    2001) (applying the Strickland ineffective-assistance standard in Iowa
    caselaw). Based on the above, my confidence in the sentencing outcome
    is definitely undermined. The district court simply did not have the benefit
    of an appropriate presentation that explained the principles of child
    psychology and applied them to the current case.
    80
    And there was a lot to work with in this case.        With a juvenile
    offender facing an adult mandatory minimum sentence, there almost
    always is.   Indeed, after examining the aspects of the record explored
    above––including abuse by his father, polysubstance abuse, teasing about
    his family’s raising of chickens, the nonobvious social and psychological
    effects of scoliosis, transfer from public school to an alternative school,
    tearful reminiscence regarding the childhood abuse and teasing inflicted
    on him, the influence of media as evidence of immaturity, the issues
    surrounding the psychology of juvenile remorse, the unchallenged use of
    the just-short-of-eighteen theory by the State, etc.––can anyone doubt that
    Majors would have benefitted had local counsel hired a consulting or
    testifying expert in child developmental psychology?         And had that
    happened, isn’t there, at the very least, a fair chance a different result
    would have occurred?
    I do not need to decide the ineffective-assistance-of-counsel issue,
    because I would reverse the sentence in this case as a result of the
    manifest errors in the analysis and remand the case for a new hearing
    consistent with the substance of this opinion. But I wish to make it very
    clear that we judges should expect, and our system of justice should
    demand, zealous and tenacious advocacy from counsel at a resentencing
    hearing. Zealous advocacy demands that a lawyer representing a juvenile
    defendant (1) be familiar with the underlying case; (2) have a good working
    knowledge of the relevant law and child development concepts applicable
    to imposition of mandatory adult sentences on juvenile offenders;
    (3) conduct a thorough, independent investigation of background facts
    that might support mitigation; and (4) present expert testimony in child
    developmental psychology to put the mitigation evidence in its proper
    context. What is plainly not acceptable is a brief review of the file and any
    81
    PSI report, a passive approach to extensive leading questions of an
    unqualified expert, a seat-of-the-pants cross-examination, a failure to call
    an expert in child psychological development, and the failure to even file a
    brief with the district court.
    The majority rules, as a matter of law, that counsel was not
    ineffective. I disagree. But at a minimum, it is hard to understand why
    the matter should not be preserved for postconviction relief to see what
    counsel did and did not do and what explanations, if any, might be
    available for the very limited defense offered in the resentencing hearing.
    The majority instead closes the door, preferring to leave the very
    substantial questions regarding the use of the State’s expert and the lack
    of appropriate expert response unexplored.
    III. Conclusion.
    I do not suggest, of course, that Majors should not be held
    responsible for his crime. The question is whether the crime “is not as
    morally reprehensible as that of an adult,” because “children are different.”
    
    Graham, 560 U.S. at 68
    , 130 S. Ct. at 2026 (quoting Thompson v.
    Oklahoma, 
    487 U.S. 815
    , 835, 
    108 S. Ct. 2687
    , 2699 (1988) (plurality
    opinion)); 
    Miller, 567 U.S. at 480
    , 132 S. Ct. at 2469. And, of course, the
    impact of our decision is not whether Majors will be released, but whether
    he is eligible to be considered for release by the parole board.
    For the reasons explained above, I would reverse the sentence in this
    case and remand the case for a real sentencing hearing in which the
    propositions that “[f]irst and foremost, the time when a seventeen-year-old
    could seriously be considered to have adult-like culpability has passed”
    and the “children are different” framework can be applied as required by
    our caselaw.
