    HECHT, Justice.
    An all-white jury in Black Hawk County convicted the defendant, a
    black man, of one count of harassment in the first degree, an aggravated
    misdemeanor under Iowa Code section 708.7(1)(b) (2015).        On appeal,
    the defendant raises several claims of error, including that the district
    court erred in using only the absolute disparity method for assessing the
    representativeness of a jury pool when considering whether the racial
    composition of the jury pool violated the defendant’s Sixth Amendment
    right to an impartial jury.   We abandon the exclusive use of absolute
    disparity as a test for jury representativeness under the Sixth
    Amendment and permit absolute disparity, comparative disparity, and
    standard deviation analyses to be used. Because the defendant’s other
    claims of error fail, we conditionally affirm his conviction and remand for
    further proceedings on the issue of whether the racial composition of the
    jury pool violated his Sixth Amendment right to an impartial jury.
    I. Factual and Procedural Background.
    Kelvin Plain Sr. and Randy Gray were neighbors with an
    acrimonious relationship who lived in a small apartment building in
    Waterloo, Iowa.   Around 11:00 p.m. on July 10, 2015, Gray and his
    spouse—both Caucasians—were asleep in their apartment when they
    were awakened by the sound of Plain—an African-American—sweeping a
    stairwell in the common area of the apartment building. Gray left his
    apartment to tell Plain to stop sweeping.       When Plain refused, an
    argument ensued.
    At trial, Gray testified that during the argument Plain went back to
    his apartment while he remained in the common area.            Plain then
    returned with “a black handle of something in his right pocket” and the
    two men continued to argue. According to Gray, Plain then told him he
    3
    had a gun and knew his mother-in-law’s car was parked outside. At that
    point, Plain exited the building and Gray followed, brandishing a golf
    club.
    Gray testified that as he stepped outside, Plain threw a pair of bolt
    cutters at his head.     Gray averred the bolt cutters hit the side of the
    apartment building so loud they made a sound he thought was a
    gunshot.
    At that point, Gray picked up the bolt cutters and stood on the
    porch of the apartment building with the golf club and prevented Plain
    from going back inside.        Gray testified Plain then threatened him
    repeatedly.
    Gray’s spouse, who had been on the phone making a 911 call
    during the argument, followed the two men outside. She testified that
    Plain threw the bolt cutters and that he threatened to shoot, cut, and
    stab her husband.
    When law enforcement officers arrived at the scene, they found
    Gray on the front porch and Plain in the yard. Plain told them he had
    been sweeping the building when Gray came out of his apartment
    waiving a golf club at him. Gray and his spouse told the officers Plain
    had thrown the bolt cutters.         After interviewing everyone involved,
    officers seized the bolt cutters and arrested Plain.
    On August 19, 2015, Plain was charged by trial information with
    harassment in the first degree in violation of Iowa Code section 708.7(2),
    an aggravated misdemeanor.
    On the first day of trial, Plain objected to the racial composition of
    the jury pool, alleging a violation of his Sixth Amendment right to an
    impartial jury.     Although African-Americans represent 8.9% of the
    population of Black Hawk County, the pool of potential jurors included
    4
    only one African-American man among fifty-six potential petit jurors—or
    1.8% of the group.      Plain did not present any evidence of systematic
    exclusion and conceded this meant he could not prove a prima facie
    case; however, he asserted this was because the jury manager did not
    provide him with the six months’ worth of data on jury pools that he
    requested.
    During trial, Plain raised a hearsay objection to testimony from the
    officer about what the officer learned from the alleged victim and his
    spouse, but the court concluded the testimony was not hearsay and
    admitted it.     Plain requested a mistrial after determining the 911
    recording in evidence contained references to his criminal history, but
    the judge denied the motion and gave a cautionary instruction instead.
    Plain objected to the prosecutor’s repeated reference to Gray as the
    “victim” during closing argument, but the court overruled the objection.
    The court also denied Plain’s request for a jury instruction addressing
    implicit racial bias.
    The jury convicted Plain of one count of harassment in the first
    degree, an aggravated misdemeanor in violation of Iowa Code sections
    708.7(1)(b) and (2). The court imposed a two-year prison sentence, but
    suspended it and ordered a term of probation running consecutively after
    a sentence on a parole violation. After filing a motion for a new trial,
    which was denied, Plain appealed. We retained the appeal.
    II. Standard of Review.
    We review constitutional issues de novo. State v. Chidester, 
    570 N.W.2d 78
    , 80 (Iowa 1997).        We review the admission of evidence
    challenged as hearsay for the correction of errors at law. State v. Dudley,
    
    856 N.W.2d 668
    , 675 (Iowa 2014).           Improperly admitted hearsay
    5
    constitutes grounds for reversal unless the proffering party establishes
    the error was not prejudicial. 
    Id. Plain’s remaining
    claims are reviewed for an abuse of discretion.
    “Trial courts have broad discretion in ruling on claims of prosecutorial
    misconduct and we review such rulings for an abuse of discretion.” State
    v. Jacobs, 
    607 N.W.2d 679
    , 689 (Iowa 2000).       We review denials of a
    mistrial and the giving of a cautionary instruction for an abuse of
    discretion. State v. Wade, 
    467 N.W.2d 283
    , 285 (Iowa 1991). Finally, we
    generally review a district court’s refusal to give a requested jury
    instruction for errors at law; however, if the jury instruction is not
    required but discretionary, we review for an abuse of discretion. Alcala v.
    Marriott Int’l, Inc., 
    880 N.W.2d 699
    , 707–08 (Iowa 2016); Herbst v. State,
    
    616 N.W.2d 582
    , 585 (Iowa 2000).
    When assessing a district court’s decision for abuse of discretion,
    we only reverse if the district court’s decision rested on grounds or
    reasoning that were clearly untenable or clearly unreasonable. 
    Dudley, 856 N.W.2d at 675
    . Grounds or reasons are untenable if they are “based
    on an erroneous application of the law or not supported by substantial
    evidence.” 
    Id. III. Analysis.
    Plain raises five issues on appeal.     First, he argues the judge
    admitted prejudicial hearsay. Second, he asserts a reference in the 911
    recording to his past criminal conduct was grounds for a mistrial. Third,
    he contends the judge improperly denied his request for an implicit-bias
    jury instruction. Fourth, he insists the prosecutor’s repeated references
    to Gray as a victim constituted prosecutorial error and violated his due
    process rights. Finally, he asserts that the racial composition of the jury
    pool violated his Sixth Amendment right to an impartial jury.
    6
    A. Prejudicial Hearsay. The first issue on appeal is whether the
    district court’s admission of testimony from an officer about what he
    learned from two witnesses—Gray and his spouse—constituted reversible
    error. We begin with the testimony at issue:
    Q. Based on your or Officer Shaaf’s conversation with
    Mr. [Gray] and [his spouse], did you learn what caused the
    mark on the [w]all? A. Yes, we did.
    Q. And what caused the mark? A.                    It was the bolt
    cutters hitting the wall after being thrown.
    The district court admitted this testimony after instructing the jury it
    could only be used as evidence of the officer’s subsequent course of
    conduct, not as evidence that the bolt cutters caused the mark on the
    wall after being thrown.
    1. Hearsay. We must first determine whether the investigating
    officer’s testimony about what he learned from the alleged victim and his
    spouse about the cause of the mark on the wall constitutes hearsay. We
    conclude that it does.
    Under Iowa law, hearsay is defined as “a statement, other than one
    made by the declarant while testifying at the trial or hearing, offered in
    evidence to prove the truth of the matter asserted.”                     Iowa R. Evid.
    5.801(c) (2015) 1.     We generally exclude hearsay from admission to the
    record, subject to the exceptions and exclusions set forth in rules 5.802
    and 5.803, because we deem it inherently unreliable—the declarant
    typically does not speak under oath and the party against whom the
    evidence is offered does not have the opportunity to cross-examine the
    1In  2016, the rule was amended. Under the new iteration of the rule, hearsay is
    defined as “a statement that: (1) [t]he declarant does not make while testifying at the
    current trial or hearing, and (2) [a] party offers to prove the truth of the matter asserted
    in the statement.” Iowa R. Evid. 5.801(c)(1)–(2) (2017).
    7
    declarant in order to test the declarant’s perception, memory, or
    narration. See State v. Smith, 
    876 N.W.2d 180
    , 185 (Iowa 2016).
    Evidence is not hearsay if it is not offered to show the truth of the
    matter asserted. State v. Mitchell, 
    450 N.W.2d 828
    , 832 (Iowa 1990). An
    out-of-court statement offered only to explain responsive conduct that is
    relevant to an aspect of the State’s case is not offered to prove the truth
    of the matter asserted and is therefore not hearsay.            
    Id. But “if
    the
    evidence is admitted, the court must limit its scope to that needed to
    achieve its purpose.” McElroy v. State, 
    637 N.W.2d 488
    , 502 (Iowa 2001).
    In deciding whether an out-of-court statement is offered to explain
    responsive conduct, the court considers “whether the statement is truly
    relevant to the purpose for which it is being offered, or whether the
    statement is merely an attempt to put before the fact finder inadmissible
    evidence.”     
    Mitchell, 450 N.W.2d at 832
    .          In several cases, we have
    concluded out-of-court statements made to law enforcement officers were
    admissible because they were truly relevant for a purpose other than to
    prove the truth of the matter asserted. In State v. Mann, for example, we
    concluded an officer’s testimony about statements from other officers
    that led her to believe someone was a victim of sexual assault was not
    hearsay when used to explain why the officer transported the alleged
    victim to a hospital for an examination.         
    512 N.W.2d 528
    , 536 (Iowa
    1994).     More recently, in State v. DeWitt, we concluded an officer’s
    testimony about information he received from a confidential source was
    not hearsay when offered to explain why the police went to a store and
    approached the defendant “rather than another customer displaying
    similar behavior.” 
    811 N.W.2d 460
    , 477 (Iowa 2012).
    In     other   cases,   we   have   rejected   claims   that    out-of-court
    declarations were admissible because they explained responsive conduct
    8
    of law enforcement officers. For example, in State v. Tompkins an officer
    testified that a witness stated a domestic abuse defendant pushed his
    girlfriend. 
    859 N.W.2d 631
    , 636 (Iowa 2015). We concluded the officer’s
    account      of   the   declarant’s   out-of-court   statement   constituted
    inadmissible hearsay because it “went beyond the mere fact that a
    conversation occurred and instead actually stated what the witness
    said.”    
    Id. at 643.
      We further concluded the out-of-court declaration
    recounted by the officer “did not merely explain the investigation” but
    instead “directly challenged [defense] counsel’s assertion” to the contrary.
    
    Id. In State
    v. Elliot, we opined that when the “investigating officer
    specifically repeats a victim’s complaint of a particular crime, it is likely
    that the testimony will be construed by the jury as evidence of the facts
    asserted.” 
    806 N.W.2d 660
    , 667 (Iowa 2011) (quoting State v. Mount, 
    422 N.W.2d 497
    , 502 (Iowa 1988), overruled on other grounds by State v.
    Royer, 
    436 N.W.2d 637
    , 639–40 (Iowa 1989)).
    Here, Plain’s overarching argument is that the State solicited the
    testimony at issue not to explain the officer’s conduct but instead to use
    the weight of the officer’s authority to bootstrap statements from the
    alleged victim and his wife about the cause of the mark on the wall. The
    State responds that the officer’s testimony is relevant to explain the
    officer’s subsequent decision to take the bolt cutters into evidence and
    Plain into custody.
    We believe this case most closely resembles the situation in
    Tompkins. Here, as in Tompkins, an officer did not merely testify that a
    conversation occurred and about the conclusions he reached as a result.
    See 
    Tompkins, 859 N.W.2d at 643
    . The officer testified that he learned
    from the alleged victim and his wife that the bolt cutters had been
    thrown, causing a mark in the wall. The jury is likely to consider such a
    9
    statement to be evidence of the fact asserted. See 
    Elliot, 806 N.W.2d at 667
    . Moreover, the State did not ask why the officer took the bolt cutters
    into evidence but instead asked what caused the mark. We think this
    fact is telling and conclude “the statement is merely an attempt to put
    before the fact finder inadmissible evidence.” See 
    Mitchell, 450 N.W.2d at 832
    .   Because the primary purpose of the testimony was to prove the
    truth of the matter asserted, as in Tompkins, we find the officer’s
    testimony about what the alleged victim and his wife told him about the
    cause of the hole in the wall to be inadmissible hearsay.
    2. Prejudice.   We must also consider whether Plain suffered
    prejudice from the admission of the hearsay evidence.          In assessing
    prejudice, we place the burden on the State to affirmatively establish that
    the admission of hearsay evidence over proper objection was not
    prejudicial.   
    Elliot, 806 N.W.2d at 669
    .     The burden to affirmatively
    establish lack of prejudice is met “if the record shows the hearsay
    evidence did not affect the jury’s finding of guilt.” 
    Id. Tainted evidence
    that is merely cumulative does not affect the jury’s finding of guilt. 
    Id. The evidence
    tending to prove Plain threw the bolt cutters was
    strong.   The State offered physical evidence that the bolt cutters were
    thrown against the wall. The evidence included a photograph of the hole
    in the wall and the bolt cutters. The bolt cutters were damaged and had
    paint markings consistent with the color of the house.          Notably, the
    physical evidence and the photograph came into the record without
    objection, see State v. McGuire, 
    572 N.W.2d 545
    , 547–48 (Iowa 1997)
    (concluding there was no prejudice where “substantially the same
    evidence [came] into the record without objection”), and it was consistent
    with the testimony given by Gray and his wife. Accordingly, we conclude
    10
    the challenged hearsay evidence was merely cumulative and therefore
    not prejudicial. See State v. Hildreth, 
    582 N.W.2d 167
    , 170 (Iowa 1998).
    In addition, the trial court gave a jury instruction limiting the
    purposes for which the hearsay testimony could be used. We have held
    that an instruction limiting the “purposes for which this evidence [can]
    be used” may serve as “an antidote for the danger of prejudice.”                   See
    State v. Putman, 
    848 N.W.2d 1
    , 15–16 (Iowa 2014).                  In this case, the
    district court instructed the jury not to consider the out-of-court
    declaration as evidence of the truth of the matter asserted and did so
    prior to the testimony being given.
    Because the officer’s testimony was cumulative of other evidence
    and the court gave an instruction limiting the purposes for which the
    evidence could be used, we find no reversible error on this issue.
    B. Reference to Past Conduct.              The second issue on appeal is
    whether the district court abused its discretion when it denied Plain’s
    motion for a mistrial after a 911 call was played to the jury that allegedly
    contained prejudicial references to Plain’s probation status and status as
    a felon. 2 We begin with the evidence at issue.
    1. The evidence at issue. During the first day of trial, the State
    played for the jury a redacted recording of a 911 call Gray’s spouse made
    during the incident.        After the trial adjourned for the night, defense
    counsel listened to the recording and heard statements on the tape that
    2Plain also attacks the content of the cautionary instruction, contending that it
    compounds the prejudicial effect of the evidence because it highlighted facts the jury
    may have otherwise missed or forgotten. We do not address the merits of this argument
    because this issue was not raised below and thus is not preserved for appeal. See
    
    DeWitt, 811 N.W.2d at 467
    . Plain requested the instruction. He did not object to its
    content, nor did the State. Thus, error was not preserved for our review. See 
    id. 11 Plain
    was wearing a GPS monitoring device and was not afraid to go
    “back to prison.” The following morning, Plain requested a mistrial.
    The district court denied the request for a mistrial, noting it had
    “not hear[d] any reference to going back to prison or the GPS device”
    when the recording was played for the jury. 3 The court offered instead to
    give a cautionary limiting instruction to the jury to alleviate any potential
    harm, if Plain wished. But the court cautioned that “from [its] listening
    to the 911 call, . . . the cautionary instruction would almost be bringing
    attention to something that they didn’t hear.”
    Defense counsel subsequently requested—and the court gave—a
    cautionary instruction. The instruction stated,
    As to . . . the 911 recording, there may have been references
    to a GPS monitoring device and/or time spent in prison. The
    jury is to disregard any statement made regarding a GPS
    monitoring device and/or time spent in prison during the
    course of your deliberation and in reaching your verdict.
    2. Discussion.      On appeal, Plain asserts the court abused its
    discretion in giving a cautionary limiting instruction instead of granting
    his motion for a mistrial.
    We must first determine whether the evidence was inadmissible.
    Under Iowa Rule of Evidence 5.404(b) (2015),
    Evidence of other crimes, wrongs, or acts is not admissible to
    prove the character of a person in order to show that the
    person acted in conformity therewith. It may, however, be
    admissible for other purposes, such as proof of motive,
    3Similarly,the State’s attorney made a professional statement suggesting he was
    not aware of objectionable statements on the redacted recording:
    Your Honor, I reviewed the 911 call several times before playing it to the
    jury. I redacted out what I could hear that was inadmissible. I reviewed
    that with [defense counsel] and actually played the portions so that she
    could hear where it was redacted. I did not hear any of the times I was
    reviewing it prior to playing it or when I was playing it these statements.
    12
    opportunity, intent, preparation, plan, knowledge, identity, or
    absence of mistake or accident.
    Rule 5.404(b) excludes evidence of other crimes not on grounds of
    relevance but “based on the premise that a jury will tend to give other
    crimes, wrongs, or acts evidence excessive weight and the belief that a
    jury should not convict a person based on his or her previous misdeeds.”
    State v. Nelson, 
    791 N.W.2d 414
    , 425 (Iowa 2010).
    Rule 5.404(b) expressly permits evidence of other crimes, wrongs,
    or acts for “proof of motive, opportunity, intent, preparation, plan,
    knowledge, identity, or absence of mistake or accident.” Iowa R. Evid.
    5.404(b). This list is not exclusive; rather, we admit evidence of other
    crimes, wrongs, or acts if there is a noncharacter theory of relevance and
    the evidence is material to a legitimate issue other than the defendant’s
    general criminal disposition. 
    Nelson, 791 N.W.2d at 425
    . Even if there is
    a noncharacter theory of relevance, “the probative value of the evidence
    [must] not [be] substantially outweighed by the danger of unfair
    prejudice to the defendant.”   State v. Cox, 
    781 N.W.2d 757
    , 761 (Iowa
    2010).
    In this case, the State did not offer a noncharacter theory of
    relevance that is probative of a factor other than a general propensity to
    commit wrongful acts. Nor does the evidence fit into a category expressly
    permitted by rule 5.404(b). Thus, the evidence of Plain’s prior criminal
    history is inadmissible under Iowa law.
    Because the evidence was inadmissible, we must determine
    whether the court abused its discretion by granting a cautionary limiting
    instruction rather than a mistrial. Generally, a district court’s decision
    not to grant a mistrial but to offer a cautionary instruction instead is
    entitled to broad deference.   See State v. Wade, 
    467 N.W.2d 283
    , 285
    (Iowa 1991).    Cautionary instructions are sufficient to mitigate the
    13
    prejudicial impact of inadmissible evidence “in all but the most extreme
    cases.” State v. Breitbach, 
    488 N.W.2d 444
    , 448 (Iowa 1992).
    In State v. Belieu, we identified several important considerations
    for determining whether a cautionary instruction can adequately mitigate
    the prejudicial impact of inadmissible evidence. 
    288 N.W.2d 895
    , 901
    (Iowa 1980).   The first Belieu consideration is whether the “defendant
    [can] combat the evidence without compounding the prejudice.” 
    Id. The second
    consideration is how extensive the evidence is and the
    promptness with which it was addressed.        
    Id. at 901–02.
      Finally, we
    assess prejudice—the stronger the State’s evidence of Plain’s guilt is, the
    less prejudicial the effect of the challenged testimony. 
    Id. at 900–01.
    Applying these three considerations to the case at hand, we
    conclude the cautionary instruction adequately mitigated any prejudicial
    impact of the evidence.    Although Plain’s counsel had opportunity to
    listen to the redacted copy of the recording before the trial, and
    apparently did listen to at least portions of it prior to trial, once the
    recording was played for the jury, Plain lacked the ability to combat the
    evidence without compounding the prejudice. See 
    id. at 901.
    However, the evidence was not extensive and the district court
    promptly addressed the matter.      See 
    id. at 901–02.
       Unlike in Belieu
    where we found numerous references to a defendant’s criminal history to
    be “so pervasive and central to the defenses that its prejudicial effect
    against this defendant could not reasonably be cured by a limiting
    instruction,” see 
    id., the references
    here were brief and inadvertently
    included in the redacted version of the recording. In such circumstances
    of brief and inadvertent presentations of evidence, we have concluded a
    cautionary instruction sufficiently managed the risk of prejudice. See,
    e.g., 
    id. at 901–02.
         Furthermore, the statements were not the
    14
    substantive focus of the recording or very obvious; they were presented
    with the background noise accompanying a phone conversation between
    a witness at the scene and a 911 operator. Indeed, neither the district
    court nor the prosecutor recalled having heard the statements when the
    recording was played for the jury. Upon learning the recording contained
    the objectionable statements, the district court acted swiftly. Although
    the court concluded a mistrial was unwarranted, the court proposed and
    gave a cautionary limiting instruction.
    Finally, the State’s evidence was strong. As we noted above, the
    State presented testimony and corroborative physical evidence and
    photographs all tending to establish that the bolt cutters were thrown
    against the wall.   Although the statements pertaining to Plain’s prior
    criminal history included in the 911 recording were inadmissible under
    rule 5.404(b), they were brief, inadvertent, and did not play a major part
    in the State’s case. Because the State’s evidence on the contested point
    was strong, the prejudicial effect of the challenged testimony is minimal.
    See 
    id. We find
    no abuse of discretion in the district court’s ruling
    denying the motion for mistrial or in giving the cautionary limiting
    instruction.
    C. Jury Instruction on Implicit Bias. The third issue on appeal
    is whether the district court’s refusal to include an antidiscrimination
    jury instruction requested by Plain constituted reversible error.       We
    generally review refusals to give jury instructions for errors at law;
    however, if the requested jury instruction is not required or prohibited by
    law, we review for abuse of discretion. 
    Alcala, 880 N.W.2d at 707
    –08.
    “Iowa law requires a court to give a requested jury instruction if it
    correctly states the applicable law and is not embodied in other
    instructions.” 
    Id. at 707
    (quoting Sonnek v. Warren, 
    522 N.W.2d 45
    , 47
    15
    (Iowa 1994)). An issue is material if it is outcome determinative. See C &
    J Vantage Leasing Co. v. Outlook Farm Golf Club, LLC, 
    784 N.W.2d 753
    ,
    756 (Iowa 2010) (“An issue is “material” [for purposes of summary
    judgment] if it might affect the outcome of the suit.”). “Parties to lawsuits
    are entitled to have their legal theories submitted to a jury if they are
    supported by the pleadings and substantial evidence in the record.”
    
    Herbst, 616 N.W.2d at 585
    (emphasis added) (quoting 
    Sonnek, 522 N.W.2d at 47
    ).
    Iowa law permits—but does not require—cautionary instructions
    that mitigate the danger of unfair prejudice. See 
    Wade, 467 N.W.2d at 285
    (recognizing decision to give cautionary instruction is discretionary);
    see also 
    Breitbach, 488 N.W.2d at 448
    (noting limiting instructions may
    be used to combat potential prejudice from improper evidence).
    Cautionary instructions include instructions that recommend a course of
    action to a jury or that limit the jury’s considerations of certain facts.
    See 
    Breitbach, 488 N.W.2d at 448
    . We review the issuance or denial of a
    requested cautionary instruction for abuse of discretion and only reverse
    if the district court’s decision rested on grounds or reasoning that were
    clearly untenable or clearly unreasonable. See State v. Newell, 
    710 N.W.2d 6
    , 18, 32–33 (Iowa 2006) (concluding issuance of cautionary
    instruction did not amount to unreasonable exercise of discretion).
    Grounds or reasons are untenable if they are “based on an erroneous
    application of the law or not supported by substantial evidence.” 
    Dudley, 856 N.W.2d at 675
    .
    In this case, the requested antidiscrimination jury instruction
    read,
    Reach your verdict without discrimination. In reaching your
    verdict, you must not consider the defendant’s race, color,
    religious beliefs, national origin, or sex. You are not to
    16
    return a verdict for or against the defendant unless you
    would return the same verdict without regard to his race,
    color, religious belief, national origin, or sex.
    Although the requested instruction correctly states the law, it does not
    concern a material issue because it is not outcome determinative;
    therefore, it is not required. On the contrary, the requested instruction
    is a cautionary instruction because it limits the jury’s consideration of
    certain facts and recommends a course of action.        See 
    Breitbach, 488 N.W.2d at 448
    .     The instruction recommends a course of action by
    asking the jurors to consciously reflect on their decisionmaking process
    and limits consideration of facts related to race, color, religious belief,
    national origin, or sex.      Because the requested instruction is a
    cautionary instruction, the district court’s refusal to give it is reviewed
    for abuse of discretion. 
    Newell, 710 N.W.2d at 32
    –33.
    The denial of a cautionary instruction constitutes an abuse of
    discretion if the district court’s decision rested on clearly untenable or
    unreasonable grounds, such as an erroneous application of law. 
    Dudley, 856 N.W.2d at 675
    ; see also 
    Newell, 710 N.W.2d at 18
    . Here, the district
    court declined to give the requested implicit-bias instruction because it
    knew of no authority approving or requiring the instruction and because
    the instruction was not included in the Iowa State Bar Association’s
    model instructions.
    As explained above, Iowa law permits cautionary instructions
    designed to mitigate the danger of unfair prejudice.       See 
    Wade, 467 N.W.2d at 285
    ; see also 
    Breitbach, 488 N.W.2d at 448
    .           Thus, the
    cautionary instruction, which is a correct statement of antidiscrimination
    principles, would have been permitted under Iowa law.         The district
    court, however, refused to give the instruction because it erroneously
    believed it lacked authority from our court to give the instruction.
    17
    Because the court’s decision rested on an error of law, it constituted an
    abuse of discretion.
    Our inquiry does not end there. “Error in giving or refusing to give
    a jury instruction does not warrant reversal unless it results in prejudice
    to the complaining party.” State v. Hoyman, 
    863 N.W.2d 1
    , 7 (Iowa 2015)
    (quoting State v. Cordero, 
    861 N.W.2d 253
    , 257–58 (Iowa 2015)). “When
    the error is not of constitutional magnitude, the test of prejudice is
    whether it sufficiently appears that the rights of the complaining party
    have been injuriously affected or that the party has suffered a
    miscarriage of justice.” State v. Marin, 
    788 N.W.2d 833
    , 836 (Iowa 2010)
    (quoting State v. Gansz, 
    376 N.W.2d 887
    , 891 (Iowa 1985)), overruled on
    other grounds by Alcala, 
    880 N.W.2d 699
    .          “We [do] not reverse for
    marginal or technical omissions . . . .” 
    Sonnek, 522 N.W.2d at 47
    . Here,
    Plain asserts an abuse of discretion, not a violation of the constitution.
    Under the facts of this case, there was strong evidence of guilt.       We
    therefore conclude the error was not prejudicial.
    While there is general agreement that courts should address the
    problem of implicit bias in the courtroom, courts have broad discretion
    about how to do so. One of the ways courts have addressed implicit bias
    is by giving jury instructions similar to the one proposed by Plain in this
    case.    We strongly encourage district courts to be proactive about
    addressing implicit bias; however, we do not mandate a singular method
    of doing so. As we conclude Plain was not prejudiced by the denial of the
    requested instruction in this case, we affirm on this issue.
    D. Prosecutor’s Use of the Term “Victim.” The fourth issue on
    appeal is whether Plain was denied his constitutional right to a fair trial
    due to prosecutorial misconduct or error.       During the State’s closing
    argument, the district court permitted the prosecutor to refer to the
    18
    complaining witness as the victim, over Plain’s objection, no fewer than
    thirty-seven times. In her rebuttal argument, the prosecutor used the
    word eleven more times. Plain argues the prosecutor’s repeated use of
    the term with the court’s tacit approval violated his constitutional right
    to a fair trial under article I, section 9 of the Iowa Constitution and the
    Fifth and Fourteenth Amendments of the United States Constitution.
    In his motion for new trial and arrest of judgment, Plain asserted
    the State’s repeated references to the complaining witness as the victim
    justified a new trial.    At the hearing on the motions, the prosecutor
    defended her actions:
    [PROSECUTOR]: It was not improper for me to
    repeatedly refer to Mr. Gray as the victim during closing
    arguments. The testimony and evidence in this case showed
    that Mr. Gray was in fact a victim. And because the
    testimony showed that, I am allowed to argue that in closing
    arguments.
    The court denied the motion.
    We consider a claim that the defendant was deprived of a fair trial
    under our doctrines of prosecutorial error and prosecutorial misconduct.
    See   State   v.   Schlitter,   
    881 N.W.2d 380
    ,   393–94   (Iowa   2016)
    (distinguishing between claims of prosecutorial error and prosecutorial
    misconduct); State v. Graves, 
    668 N.W.2d 860
    , 869 (Iowa 2003)
    (synthesizing our prosecutorial misconduct doctrine).          In order to
    establish a violation of the right to a fair trial, a defendant must show
    both (1) error or misconduct and (2) prejudice. State v. Krogmann, 
    804 N.W.2d 518
    , 526 (Iowa 2011).
    1. Prosecutorial behavior. The defendant must first establish the
    prosecutor violated a prosecutorial duty. Prosecutors have a special role
    in our criminal justice system.         A prosecutor is not the ordinary
    advocate, at least in the sense that “a prosecutor owes a duty to the
    19
    defendant as well as to the public.”        
    Graves, 668 N.W.2d at 870
    .
    Although a prosecutor should zealously and lawfully advocate on behalf
    of the State, “the prosecutor’s primary interest should be to see that
    justice is done, not to obtain a conviction.” 
    Id. Thus, we
    impose special
    duties on prosecutors to ensure they act in accordance with the special
    role with which they are entrusted. See, e.g., 
    id. (“[I]t is
    improper to ask
    the defendant whether another witness has lied.”); DeVoss v. State, 
    648 N.W.2d 56
    , 64 (Iowa 2002) (noting the prosecutor must “assure the
    defendant a fair trial”).
    We set forth standards governing a prosecutor’s duty to the
    defendant during closing arguments in Graves. 
    See 668 N.W.2d at 874
    .
    There we stated that although we accord prosecutors “some latitude” to
    analyze evidence and argue “reasonable inferences and conclusions to be
    drawn from the evidence,” we do not permit a prosecutor to “express his
    or her personal beliefs.” 
    Id. We emphasized
    that prosecutors may not
    “vouch personally as to a defendant’s guilt or a witness’s credibility.” 
    Id. (quoting State
    v. Williams, 
    334 N.W.2d 742
    , 744 (Iowa 1983)).           We
    stressed that
    [t]his is true whether the personal belief is purportedly based
    on knowledge of facts not possessed by the jury, counsel’s
    experience in similar cases, or any ground other than the
    weight of the evidence in the trial. A defendant is entitled to
    have the case decided solely on the evidence.
    
    Id. (emphasis added)
    (quoting 
    Williams, 334 N.W.2d at 744
    ).              “In
    addition, the prosecutor is ‘not allowed to make inflammatory or
    prejudicial statements regarding a defendant in a criminal action.’ ” 
    Id. (quoting State
    v. Leiss, 
    258 Iowa 787
    , 792, 
    140 N.W.2d 172
    , 175 (1966)).
    A defendant’s constitutional right to a fair trial is violated if a
    prosecutor fails to comply with the requirements of due process at the
    20
    trial, whether by virtue of prosecutorial error or misconduct.4 
    Id. at 870.
    In addressing fair-trial challenges based on prosecutorial behavior, we
    first determine whether the prosecutor violated a duty to the defendant.
    See 
    id. If so,
    we consider whether that violation was intentional or
    reckless.     
    Schlitter, 881 N.W.2d at 394
    .           An intentional or reckless
    violation amounts to prosecutorial misconduct while an unintentional
    violation amounts only to prosecutorial error.             
    Id. We then
    determine
    whether the error caused prejudice.
    The behavior at issue here is the prosecutor’s use of the term
    “victim” twenty-five times during her closing argument over Plain’s
    objection to refer to Gray, the State’s complaining witness.                       The
    prosecutor used the term ten more times during her rebuttal argument.
    Plain contends this repeated use of the “victim” descriptor denied him a
    fair trial because it impermissibly expressed the prosecutor’s opinion
    that a crime was, in fact, committed and that Gray was Plain’s victim.
    The State rejoins that the prosecutor violated no rule when she engaged
    in spirited advocacy drawing conclusions and arguing inferences
    reasonably flowing from the record pertaining to Gray’s role in the
    occurrence that was the subject of the trial.
    4We  recently cautioned against conflating prosecutorial error with prosecutorial
    misconduct in 
    Schlitter, 881 N.W.2d at 393
    –94. In that case, we distinguished between
    the two terms as follows:
    Prosecutorial misconduct includes those statements “where a prosecutor
    intentionally violates a clear and unambiguous obligation or standard
    imposed by law, applicable rule or professional conduct,” as well as
    “those situations where a prosecutor recklessly disregards a duty to
    comply with an obligation or standard.” Prosecutorial error occurs
    “where the prosecutor exercises poor judgment” and “where the attorney
    has made a mistake” based on “excusable human error, despite the
    attorney’s use of reasonable care.”
    
    Id. (citations omitted)
    (quoting Shawn E. Minihan, Measuring Prosecutorial Actions: An
    Analysis of Misconduct Versus Error, Prosecutor, Dec. 2014, at 23–25).
    21
    Other courts have confronted the question of whether a state’s use
    of the “victim” descriptor interferes with a defendant’s right to a fair trial.
    The decisions of those courts reveal that the propriety of the use of the
    descriptor depends in part on the stage of the trial and the context in
    which it was used. The Court of Appeals of Texas has concluded a trial
    court’s use of the term “victim” rather than “alleged victim” in jury
    instructions constituted reversible error in a case in which the sole issue
    was   whether    the   complainant     consented    to   sexual   intercourse.
    Talkington v. State, 
    682 S.W.2d 674
    , 675 (Tex. Ct. App. 1985); see also
    Veteto v. State, 
    8 S.W.3d 805
    , 816 (Tex. Ct. App. 2000) (concluding use of
    the term “victim” rather than “alleged victim” in describing the
    complaining witness in a jury instruction constituted an “improper
    comment on the weight of the evidence by the court”), abrogated by State
    v. Crook, 
    248 S.W.3d 172
    , 176–77 (Tex. Crim. App. 2008).
    A prosecutor’s use of the word “victim” has not, however, been
    deemed by other courts to be categorically improper when used in other
    contexts in criminal cases. The Delaware Supreme Court has noted, for
    example, that the term “victim” is routinely used in indictments in that
    state to describe the state’s complaining witness. Jackson v. State, 
    600 A.2d 21
    , 24 (Del. 1991).     The same court rejected a claim that a trial
    court committed plain error in allowing a police officer and an FBI
    forensics expert called by the state to use the word “victim” in their
    testimony because law enforcement officers use the descriptor as a “term
    of art synonymous with ‘complaining witness.’ ” 
    Id. at 24–25.
    But the use of the “victim” descriptor by prosecutors during
    criminal trials has been found improper by other courts in certain
    contexts. Although infrequent or isolated utterance of the word “victim”
    by a prosecutor in conveying the state’s position that specific evidence
    22
    supports a conviction has been found permissible, pervasive use of the
    word by a prosecutor during the presentation of evidence and during
    closing argument has been disapproved. Compare State v. Warholic, 
    897 A.2d 569
    , 584 (Conn. 2006) (concluding prosecutor’s two closing
    argument references to a child as the victim were likely understood by
    the jury as reflecting the state’s contention “that, based on the state’s
    evidence, the complainant was the victim of the alleged crimes” and,
    therefore, not improper), with State v. Albino, 
    24 A.3d 602
    , 617 (Conn.
    App. 2011) (concluding prosecutor’s twenty-seven references to “victim”
    and repeated references to “murder” and “murder weapon” during
    evidentiary phase of trial and in closing argument were improper in a
    case in which the defendant asserted self-defense).
    Emphasizing the importance of the context in which the word is
    used, the Delaware Supreme Court has concluded the state’s use of the
    term during trial causes no cognizable harm “when there is no doubt
    that a crime was committed and simply the identity of the perpetrator is
    in issue.” 
    Jackson, 600 A.2d at 24
    . However, the court cautioned that a
    prosecutor’s repeated use of the term is improper “in a case where
    consent [is] the sole defense, and the principal issue one of credibility.”
    
    Id. at 25,
    clarified on rehearing en banc.     The court reasoned that in
    cases in which the parties dispute whether a crime has been committed,
    “it is incompatible with the presumption of innocence for the prosecutor
    to refer to the complaining witness as the ‘victim,’ just as it is to refer to
    the defendant as a ‘criminal.’ ” 
    Id. With these
    principles in mind, we turn to the record.            Plain’s
    defense theory was to characterize the transaction as a mere argument
    between neighbors. Through cross-examination and argument, defense
    counsel sought to persuade the jury that the neighbors’ argument was
    23
    initiated and continued by Gray. Counsel further posited that the State’s
    evidence tending to prove Plain threatened Gray or threw the bolt cutter
    at him was incredible and that no crime was committed. The prosecutor
    consistently and repeatedly referenced Gray as the victim during her
    closing and rebuttal arguments, making no discernible effort to link that
    descriptor to any specific evidence in the record.
    Although    we   conclude   the   prosecutor   erred   during   closing
    argument in persistently using the term “victim” to refer to the
    complaining witness under the circumstances of this case, we do not find
    that the prosecutor intentionally violated her duty. At the hearing on the
    motion for new trial and arrest of judgment, the prosecutor indicated she
    believed her use of the term was justified because the evidence and
    testimony established Gray was a victim under the circumstances of this
    case. Because the limitations on the proper use of the term “victim” by
    prosecutors in this jurisdiction were not clear at the time of Plain’s trial,
    we cannot conclude the prosecutor committed misconduct.
    2. Prejudice.    We next consider whether the prosecutor’s error
    “resulted in prejudice to such an extent that the defendant was denied a
    fair trial.”   
    Graves, 668 N.W.2d at 869
    .    In determining prejudice, we
    consider
    (1) the severity and pervasiveness of the misconduct; (2) the
    significance of the misconduct to the central issues in the
    case; (3) the strength of the State’s evidence; (4) the use of
    cautionary instructions or other curative measures; and (5)
    the extent to which the defense invited the misconduct.
    
    Id. (citations omitted)
    .
    Applying these factors to the case at hand, we find insufficient
    prejudice to merit reversal on this issue. A couple of the factors weigh in
    favor of a finding of prejudice. In particular, we note the defendant did
    nothing to invite the prosecutor’s behavior and affirmatively objected to it
    24
    without avail.      Also, whether Gray was a victim was highly central to
    Plain’s defense that no crime was committed.
    Other factors weigh more strongly against a determination that
    Plain suffered prejudice. First, we note the prosecutor’s use of the term
    “victim” was limited to closing arguments and the district court
    instructed jurors that “[the] summations and closing arguments of
    counsel are not evidence,” thus mitigating the term’s prejudicial effect.
    Second, we find the physical and photographic evidence in this case, the
    direct evidence of verbal threats made by Plain and recorded on the 911
    call, and the consistent witness testimony presented by the State are
    strong evidence in support of Plain’s conviction.                       Accordingly, we
    conclude the prosecutorial error was not prejudicial and thus do not
    reverse on this basis.
    E. Sixth Amendment Right to Impartial Jury. The final issue
    on appeal is whether the racial composition of the jury pool violated
    Plain’s Sixth Amendment right to an impartial jury. As we have noted,
    the jury pool in Plain’s case only contained one African-American man
    among fifty-six potential petit jurors. 5               Although African-Americans
    comprise 8.9% of Black Hawk County’s population overall, they
    represented only 1.8% of the jury pool summoned for Plain’s trial. Plain,
    who is African-American, objected to the composition of the jury pool and
    requested a new panel.           The district court overruled his objection and
    denied his request.
    5Under    Iowa’s jury-selection statutes, a jury “pool” (i.e. venire) consists of all
    persons who are summoned for jury service and who report. Iowa Code § 607A.3(9). A
    jury “panel” consists of “those jurors drawn or assigned for service to a courtroom,
    judge, or trial.” 
    Id. § 607A.3(7).
    And a “petit” jury (i.e. grand jury) consists of the jurors
    who are actually called upon to attend court proceedings. See 
    id. § 607A.3(3).
                                               25
    1. The right to an impartial jury.           The Sixth Amendment to the
    United States Constitution provides that “[i]n all criminal prosecutions,
    the accused shall enjoy the right to a speedy and public trial, by an
    impartial jury of the State and district wherein the crime shall have been
    committed.” 6     U.S. Const. amend. VI.           The right to an impartial jury
    entitles the criminally accused to a jury drawn from a fair cross-section
    of the community. Taylor v. Louisiana, 
    419 U.S. 522
    , 530, 
    95 S. Ct. 692
    ,
    697–98 (1975).
    A jury that represents a fair cross-section of the community
    enables “the commonsense judgment of the community [to serve] as a
    hedge against the overzealous or mistaken prosecutor and in preference
    to the professional or perhaps overconditioned or biased response of a
    judge.” 
    Id. at 530,
    95 S. Ct. at 698.            It also helps legitimize the legal
    system and is “critical to public confidence in the fairness of the criminal
    justice system.” 
    Id. Finally, it
    encourages civic participation through the
    shared administration of justice. 
    Id. 2. The
    Duren three-part test. In Duren v. Missouri, the Supreme
    Court defined a three-part test for establishing a violation of the fair
    cross-section requirement. 
    439 U.S. 357
    , 364, 
    99 S. Ct. 664
    , 668 (1979);
    see also State v. Watkins, 
    463 N.W.2d 411
    , 414 (Iowa 1990). Under this
    three-part test, a defendant can establish a prima facie violation of the
    fair cross-section requirement by showing
    (1) that the group alleged to be excluded is a ‘distinctive’
    group in the community; (2) that the representation of this
    6Article I, section 10 of the Iowa Constitution also entitles a criminal defendant
    to a jury pool that represents a fair cross-section of the community. See State v.
    Knutson, 
    220 N.W.2d 575
    , 577 (Iowa 1974). The defendant has not raised a challenge
    under article I, section 10, however, so we do not consider in this case whether the
    protection offered by that provision is identical to that provided under the Sixth
    Amendment.
    26
    group in venires from which juries are selected is not fair
    and reasonable in relation to the number of such persons in
    the community; and (3) that this underrepresentation is due
    to systematic exclusion of the group in the jury-selection
    process.
    
    Duren, 439 U.S. at 364
    , 99 S. Ct. at 668. If the defendant establishes a
    prima facie case, the burden shifts to the state to justify the
    disproportionate representation by proving “a significant state interest” is
    “manifestly   and    primarily   advanced”     by    the   causes    of   the
    disproportionate exclusion. 
    Id. at 367–68,
    99 S. Ct. at 670.
    Under   the   first Duren prong,     a   defendant   must     establish
    membership in a distinctive group under community standards, id. at
    
    364, 99 S. Ct. at 668
    , meaning a community group with “a definite,
    objectively ascertainable membership” that “constitutes a substantial
    segment of the population” and has “common and unique opinions,
    attitudes, and experiences” that cannot be adequately represented by
    members of the general population.       Thomas M. Fleming, Age Group
    Underrepresentation in Grand Jury or Petit Jury Venire, 
    62 A.L.R. 4th 859
    ,
    867 (1988).     In other words, a defendant must show she has
    “characteristics that are relevant to constituting a jury venire that is
    representative of the community.”     David M. Coriell, Note, An (Un)fair
    Cross Section: How the Application of Duren Undermines the Jury, 100
    Cornell L. Rev. 463, 480 (2015) [hereinafter Coriell].     Under Iowa and
    federal law, these characteristics might include race, color, religion, sex,
    national original, or economic status. Compare Iowa Code §§ 607A.2, .4,
    .10, .19–.22, with 28 U.S.C. §§ 1862, 1864 (2012).
    Under the second Duren prong, a defendant must establish the
    proportion of group members in the jury pool is underrepresentative of
    the proportion of group members in the community.          See, e.g., 
    Duren, 439 U.S. at 364
    –66, 99 S. Ct. at 669. The second prong “distinguishes
    27
    between acceptable and unacceptable levels of deviation for the
    representation of a distinctive group on a jury venire from their
    representation in the community.” Coriell, 100 Cornell L. Rev. at 480.
    To measure representation, jurisdictions generally apply one or more of
    the following statistical tests: (1) absolute disparity, (2) comparative
    disparity, and/or (3) standard deviation.                United States v. Hernandez-
    Estrada, 
    749 F.3d 1154
    , 1160 (9th Cir. 2014). 7
    The first test, absolute disparity, is useful as a quick dipstick for
    providing a rough gauge of the representativeness of a jury pool. United
    States v. Rogers, 
    73 F.3d 774
    , 777 (8th Cir. 1996) (panel decision).
    Absolute disparity is calculated “by taking the percentage of the distinct
    group in the population and subtracting from it the percentage of that
    group represented in the jury panel.” State v. Jones, 
    490 N.W.2d 787
    ,
    793 (Iowa 1992).               The lower the resulting percentage, the more
    representative the jury pool. 8
    The absolute disparity formula does not account for the relative
    size of the minority group in the general population. It instead excludes
    any minority population that makes up a percentage of the population
    7Hernandez-Estrada       also discusses the absolute impact test, which is similar to
    the absolute disparity test.
    Under [the absolute impact] approach, the initial calculation is the same
    as for the absolute disparity test. However, the resulting number is then
    multiplied by the number of persons on the particular panel. . . . The
    advantage of the test is that it applies the disparity analysis to the actual
    jury pool to determine the impact. However, because it is based on the
    absolute disparity test, the absolute impact test bears many of the same
    flaws.
    
    Hernandez-Estrada, 749 F.3d at 1162
    .
    8Courts  set different standards for what constitutes an absolute disparity that is
    not a fair and reasonable representation. See 
    Jones, 490 N.W.2d at 793
    (noting other
    courts have found absolute disparities of anywhere from 2.9% to 10% insufficient to
    establish a prima facie case).
    28
    that is lower than the permissible amount for absolute disparity.       For
    example, if absolute disparity is established at ten percent, see 
    id., then it
    excludes any minority population that accounts for less than ten
    percent of the population from the Sixth Amendment’s protections.
    The second test, comparative disparity, is useful in examining the
    relative size of the minority group in the general population. 
    Rogers, 73 F.3d at 777
    (“[I]t calculates the representation of African Americans in
    jury pools relative to the African-American community rather than
    relative to the entire population.”). Comparative disparity is calculated
    by dividing the absolute disparity by the percentage of the population
    represented by the group in question. See United States v. Sanchez, 
    156 F.3d 875
    , 879 n.4 (8th Cir. 1998). The higher the comparative disparity
    percentage, the less representative the jury pool.
    The primary shortcoming of the comparative disparity test is that it
    can overstate underrepresentation for groups with a small population
    percentage.    
    Hernandez-Estrada, 749 F.3d at 1163
    (“Let’s assume, for
    example, that a group constitutes .1% of the population, with no
    representation in the jury pool. The comparative disparity of that group
    would be 100%. Few would argue that the absence of a group
    representing just 0.1% of the population violates the fair cross-section
    requirement,    yet   comparative   disparity   analysis   would    suggest
    otherwise.”). In addition, with very large groups, comparative disparity
    tends to validate deviations that are not produced by chance even though
    that can alter the representativeness of the average jury significantly. 
    Id. The final
    test, standard deviation, is useful to measure “predicted
    fluctuations from the expected value.”     Castaneda v. Partida, 430 U.S
    482, 496 n.17, 
    97 S. Ct. 1272
    , 1281 n.17 (1977). Standard deviation is
    calculated by analyzing a sample taken from the voter wheel and
    29
    analyzing it for randomness and fluctuations. Id.; see also United States
    v. Weaver, 
    267 F.3d 231
    , 238–39 (3d Cir. 2001).
    Standard deviation, too, is an imperfect test for assessing
    disproportional minority representation.               Measures of the standard
    deviation presume randomness; however, the chances of drawing a
    particular jury composition are not random, in part because “the
    characteristics of the general population differ from a pool of qualified
    jurors.” 
    Hernandez-Estrada, 749 F.3d at 1163
    .
    Under the third Duren prong, a defendant must establish that
    systematic exclusion of the group caused the underrepresentation of the
    group. 9 See 
    Duren, 439 U.S. at 364
    , 99 S. Ct. at 668. The third prong
    9The Sixth and Fourteenth Amendments both protect the impartiality of a jury.
    See Nina W. Chernoff, Wrong About the Right: How Courts Undermine the Fair Cross-
    Section Guarantee by Confusing It with Equal Protection, 64 Hastings L.J. 141, 151–52
    (2012) [hereinafter Chernoff I]. While the Fourteenth Amendment’s Equal Protection
    Clause bars the intentional exclusion of protected minority groups, the Sixth
    Amendment guarantees that minority groups will not be systematically excluded, even
    where there is no evidence of intentional exclusion. Coriell, 100 Cornell L. Rev. at 472
    (“[W]hile equal protection is a powerful tool to combat intentional discrimination in
    drafting the jury venire, it is less effective in addressing situations where there is
    obvious underrepresentation of certain segments of the community on jury venires but
    no evidence of intentional exclusion on the part of state actors.”).
    In this case, the State asserts the defendant did not establish evidence of
    discriminatory intent. The State conflates the test for a violation of the Equal Protection
    Clause (which requires a showing of intent) with the test for a violation of the Sixth
    Amendment (which does not). See Chernoff I, 64 Hastings L.J. at 151–52.
    For an example of how there can be systematic exclusion without discriminatory
    intent, consider an example from Hartford, Connecticut, where
    Unbeknownst to the jury office, an inadvertent error caused the
    computer program to erroneously read the “d” in the capital city of
    Hartford to mean “deceased.” The computer program accordingly never
    selected anyone from Hartford to receive a jury summons. . . .
    The computer program also failed to send jury summons to
    anyone in the neighboring city of New Britain, the second largest city in
    the jury district. The New Britain citizens were left out of the jury pool
    because the source list of names from New Britain was accidentally
    misplaced and was never entered into the computer program.
    30
    “distinguishes between situations where a particular jury venire is
    nonrepresentative and those situations where the jury venires in a
    district are continuously nonrepresentative of the community.” Coriell,
    100 Cornell L. Rev. at 481.            To establish systematic exclusion, a
    defendant must establish the exclusion is “inherent in the particular
    jury-selection process utilized” but need not show intent.             
    Duren, 439 U.S. at 366
    , 
    99 S. Ct. 669
    .       In other words, the defendant must show
    evidence of a statistical disparity over time that is attributable to the
    system for compiling jury pools. Coriell, 100 Cornell L. Rev. at 481. “If
    there is a pattern of underrepresentation of certain groups on jury
    venires, it stands to reason that some aspect of the jury-selection
    procedure is causing that underrepresentation.” Id.; accord 
    Duren, 439 U.S. at 366
    , 99 S. Ct. at 669–70.
    3. State v. Jones. We initially endorsed the absolute disparity test
    and rejected the comparative disparity test in Jones. 
    See 490 N.W.2d at 793
    . In Jones, a five-justice panel of our court considered whether the
    Scott County procedure for compiling a jury list that relied solely on voter
    registration lists and drivers’ license records violated the fair cross-
    section requirement of the Sixth Amendment. 
    Id. at 791–92.
    The jury
    panel at issue in that case consisted of less than 3.5% African-Americans
    while Scott County was 4.1% African-American. 
    Id. Concluding that
    the United States Supreme Court had adopted the
    absolute disparity test, we expressly rejected the comparative disparity
    __________________________

    African-American population and 68% of the voting-age Hispanic
    population in the jury district.

    31
    test.   
    Id. at 793.
      Citing precedents from the United States Courts of
    Appeals for the Eighth and Ninth Circuits, we concluded an absolute
    disparity of 1.5% was not unfair or unreasonable under Duren. 
    Id. We affirmed
    two other cases in which the absolute disparity test
    was utilized in the early 1990s. In State v. Huffaker, we concluded an
    absolute disparity of 2.85% between the number of African-Americans in
    Polk County (4.52%) and the percentage of African-Americans in the jury
    venire (1.67%) was not sufficient to constitute a violation of Duren’s
    second prong. See 
    493 N.W.2d 832
    , 833–34 (Iowa 1992). In Thongvanh
    v. State, we decided a 0.18% absolute disparity between Asians selected
    for jury duty (0%) and Asians in the general population of a county
    (.18%) did not violate the fair cross-section requirement.       
    494 N.W.2d 679
    , 683 (Iowa 1993).
    i. Courts criticize the absolute disparity test. At the time they were
    decided, the scope of the Supreme Court’s decisions in Swain v.
    Alabama, 
    380 U.S. 202
    , 
    85 S. Ct. 824
    (1965), and Castaneda, 
    430 U.S. 482
    , 
    97 S. Ct. 1272
    , was unclear. We mistakenly viewed the Supreme
    Court’s acknowledgement of the absolute disparity test in Swain and
    Castaneda as tacit approval of the absolute disparity model of statistical
    computation. See 
    Jones, 490 N.W.2d at 792
    –93 (discussing 
    Swain, 380 U.S. at 208
    –09, 85 S. Ct. at 829, and 
    Castaneda, 430 U.S. at 495
    , 97
    S. Ct. at 1280).        After Jones was decided, the Supreme Court
    acknowledged the comparative disparity formula and followed a case-by-
    case approach permitting consideration of the results of multiple
    analytical models. Berghuis v. Smith, 
    559 U.S. 314
    , 329–30, 
    130 S. Ct. 1382
    , 1393 (2010) (discussing People v. Smith, 
    615 N.W.2d 1
    , 2 (Mich.
    2000), and Smith v. Berghuis, 
    543 F.3d 326
    , 338 (6th Cir. 2008), rev’d
    and remanded on other grounds, 
    559 U.S. 314
    , 
    130 S. Ct. 1382
    (2010)).
    32
    Thus, we can no longer say that the Supreme Court’s acknowledgement
    of the absolute disparity model is a preference for that approach.
    Further, our decision in Jones relied on authorities from the
    United States Courts of Appeals for the Eighth and Ninth Circuits.
    Shortly after we decided Jones, the Eighth Circuit affirmed a defendant’s
    conviction under Eighth Circuit precedent but sharply criticized the
    circuit’s reliance on absolute disparity analysis and opined that the
    comparative disparity model should also be used.       
    Rogers, 73 F.3d at 775
    –76.   Subsequently, the Ninth Circuit expressly overruled its prior
    precedent that had deemed the absolute disparity formula to be the
    exclusive analytical tool. See 
    Hernandez-Estrada, 749 F.3d at 1163
    .
    ii. Practical issues with Jones.     Exclusive use of the absolute
    disparity test creates problems of constitutional significance in Iowa.
    The test offers less protection for a minority group as the group’s
    percentage of the community’s total population decreases. 
    Id. at 1162.
    In adopting the absolute disparity test in Jones, we noted that the
    Supreme Court had determined that “the underrepresentation of as
    much as ten percent” did not establish a prima facie case for the second
    Duren 
    prong. 490 N.W.2d at 793
    .
    The shortcoming of the absolute disparity formula is demonstrated
    by the fact that African-Americans do not represent more than ten
    percent of the population in any county in Iowa.         See Iowa Black
    Population Percentage, 2013 by County, www.indexmundi.com/facts/
    united-states/quick-facts/iowa/black-population-percentage#chart (last
    visited June 27, 2017).    In the seven Iowa counties with the highest
    African-American population—Black Hawk (8.9%), Scott (7.4%), Polk
    (6.5%), Des Moines (5.7%), Johnson (5.5%), Linn (4.3%), and Webster
    (4.1%)—an     African-American     could    not   establish    a     racially
    33
    unrepresentative jury using the absolute disparity model under the Sixth
    Amendment even if the exclusion of African-Americans was total and
    systematic.     Outside of the Hispanic and Latino population, no Iowa
    county has a minority population that rises above the ten-percent floor
    referenced in Jones. Such a result is at odds with the Sixth Amendment
    and the purposes of the fair cross-section requirement.
    A test without teeth leaves the right to an impartial jury for some
    minority      populations    without     protection.     Empirical     evidence
    overwhelmingly shows that having just one person of color on an
    otherwise all-white jury can reduce disparate rates of convictions
    between black and white defendants. For example, when researchers at
    Duke University compared data on conviction rates by race in over 700
    criminal trials over a ten-year period, they found that where there was
    one or more black jurors, black and white defendants had roughly equal
    rates of conviction; however, all-white juries convicted African-American
    defendants 81% of the time and white defendants only 66% of the time.
    Shamena Anwar, et al. The Impact of Jury Race in Criminal Trials, 127
    Q.J. Econ. 1017, 1027–28, 1032 (2012).
    The data evidencing the impact of racially unrepresentative juries
    on case outcomes are especially troubling given that Iowa ranks worst in
    the nation for the percentage of our prison population that is African-
    American (more than 25%), while African-Americans represent just 3.3%
    of the state’s population. Kyle Munson, Black-White Disparities Persist in
    Iowa,     Des    Moines     Register   (last   updated    July   12,     2015),
    http://www.desmoinesregister.com/story/news/local/kyle-munson/
    2015/07/12/black-iowa-statistics-economics-incarceration/30059517.
    Troubling, too, is the fact that African-Americans in Iowa are ten times
    more likely to be arrested than persons of other races; and Iowa ranks
    34
    third worst in the nation for our incarceration rate for black men
    (9.4%). 10      
    Id. A sound
    formula for assessing underrepresentation of
    minorities in our jury pools must provide meaningful protections of the
    right to an impartial jury.
    4. The second Duren prong.              Our decision to adopt absolute
    disparity as the exclusive test and to reject comparative disparity in
    Jones rested upon an error of law and on cases from other jurisdictions
    that have since been overruled or criticized. After surveying the various
    tests, and bearing in mind the practical problems associated with the use
    of the absolute disparity test in Iowa, we conclude it is no longer
    appropriate to rely exclusively upon the absolute disparity test as an
    indicator of representativeness. We therefore overrule 
    Jones, 490 N.W.2d at 792
    –93.
    A sizeable number of jurisdictions consider more than one
    analytical model when making determinations about whether a jury pool
    constitutes a fair and reasonable cross-section of the community. 11 Like
    10The  high arrest and incarceration rates have secondary effects, too, presenting
    barriers for education and employment and contribute to high percentages of families
    living in poverty (39% for black families versus 13.9% statewide), receiving food stamps
    (42% for black households versus 11% for white households), rental housing (73.4% for
    black Iowans versus 29.2% statewide), median income ($27,406 for black households
    versus $52,652 for white households), unemployment (11.6% for black Iowans versus
    4.8% overall), health insurance pre-Affordable Care Act (44% of black Iowans versus
    77% of white Iowans), dropout rates (14% for black children who make up just 5% of
    the school population), and bachelor degrees (15% for black Iowans versus 26% overall).

    the Ninth Circuit, we decide “not [to] prescribe an alternative exclusive
    analysis to be applied in every case” and to follow the Supreme Court in
    permitting multiple analyses to be used that are appropriate to the
    circumstances of each case. See 
    Hernandez-Estrada, 749 F.3d at 1164
    .
    Parties   challenging     jury    pools    on   the    ground     that   they    are
    unrepresentative may base their challenges on multiple analytical
    models.    The district court may use multiple analytical models in its
    analysis, taking into account the various strengths and weaknesses of
    each test when determining whether jury pools comport with the Sixth
    Amendment mandate of representativeness.
    This flexible approach is consistent with the nature of the Sixth
    Amendment right to have a jury pool made up of a fair cross-section of
    the community. What constitutes a fair cross-section of the community
    is subject to change over time. See 
    Taylor, 419 U.S. at 537
    , 95 S. Ct. at
    701 (noting the definition of “community” is subject to change because
    “[c]ommunities differ at different times and places”). “What is a fair cross
    section at one time or place is not necessarily a fair cross section at
    another time or a different place.”         
    Id. (noting that
    although the total
    exclusion of women was permitted at one time, women could no longer
    be excluded at all on account of their sex). Because what constitutes a
    fair cross-section of the community is a fluid concept, a flexible approach
    for determining when a racial disparity rises to the level of a
    constitutional violation is warranted.
    5. The third Duren prong.          The State argues that even if we are

    the benefits of the comparative disparity calculation justify overruling
    Jones, we should not change course in this case because Plain did not
    present evidence under the third factor, which is required to establish a
    prima facie case. Plain contends that any failure to present a prima facie
    case on the third prong was caused by the jury manager’s denial of his
    request for access to the information necessary to compile historical data
    on the composition of juries in Black Hawk County.
    Plain’s counsel recounted, during a colloquy with the court, her
    effort to obtain the relevant historical data.
    [F]or purposes of preserving the record at least . . . I also
    have what I was hoping would be better[, which] I’ve marked

    statistics for the last six months. She says she can only print
    off today’s panel in this courtroom. So I guess I just want to
    enter these for purposes of the record. I understand that I
    haven’t met my burden with the prima facie case. I’d concede
    that. But since I’ve tried to make the motion, I’d at least like
    to supplement the record.
    In Iowa, the constitutional right to an impartial jury is enshrined
    in and implemented by statute.       See Iowa Code §§ 607A.1–.47 (2016).
    Iowa’s jury laws are loosely based on the federal jury laws.       Compare
    Iowa Code §§ 607A.1–.47, with 28 U.S.C. §§ 1861–78. The statutes in
    the state and federal systems describe in detail the procedures and
    standards for compiling jury pools.        In each instance, their essential
    purpose is to implement the constitutional right to a jury.
    Importantly, the state and federal statutes require the selection
    authorities to maintain all records and lists concerning the selection of
    jurors for a period of at least four years. Compare Iowa Code § 607A.26,
    with 28 U.S.C. § 1868. Unlike the federal law, however, which requires
    the selection authority to make the records and papers it compiled and
    37
    maintained    “available   for   public    inspection   for   the   purpose   of
    determining the validity of the selection of any jury,” 28 U.S.C. § 1868,
    the Iowa Code does not expressly require the state to provide access to
    the data and information that must be maintained, see Iowa Code
    § 607A.26.
    In at least four jurisdictions that lack a state statute establishing
    the right and procedures for obtaining the information necessary to
    enforce an individual’s Sixth Amendment rights, courts have determined
    that the constitution mandates access even if statutes do not. See Nina
    W. Chernoff, No Records, No Right: Discovery & the Fair Cross-Section
    Guarantee, 
    101 Iowa L
    . Rev. 1719, 1763 (2016) [hereinafter Chernoff II]
    (reviewing cases).
    The Supreme Court of Missouri, for example, reasoned that the
    “cross-section requirement would be without meaning if a defendant
    were denied all means of discovery in an effort to assert that right.” State
    ex rel. Garrett v. Saitz, 
    594 S.W.2d 606
    , 608 (Mo. 1980) (en banc). In
    holding that a defendant “is entitled to information relating to the racial
    composition of the grand jury so that he may assess whether he has a
    viable constitutional challenge,” the Nevada Supreme Court reasoned
    that “[w]ithout this information, [the defendant]’s ability to show a
    potential violation of his constitutional right to a grand jury drawn from a
    fair cross-section of the community is limited.” Afzali v. State, 
    326 P.3d 1
    , 1, 3 (Nev. 2014).       The Superior Court of New Jersey, Appellate
    Division, determined “[i]t would be virtually impossible for defendants
    who are endeavoring to ascertain if a successful attack on the grand jury
    selection process can be advanced if the facts necessary to prove a defect
    in the selection process are withheld.”       State v. Ciba-Geigy Corp., 573
    
    38 A.2d 944
    , 950 (N.J. Super. App. Div. 1990); accord Mobley v. United
    States, 
    379 F.2d 768
    , 773 (5th Cir. 1967).
    Like the courts in Missouri, Nevada, and New Jersey, we conclude
    the constitutional fair cross-section purpose alone is sufficient to require
    access to the information necessary to prove a prima facie case. Those
    courts
    were each faced with a criminal defendant’s request for data
    on the racial and ethnic composition of the jury pool. Each
    court acknowledged that their state had no statutory
    equivalent to the [Federal Jury Selection and Service Act
    (JSSA)], and each granted the defendant’s request for jury
    data on purely constitutional grounds, recognizing that
    access was necessary to enforcement of the fair cross-section
    right.
    Chernoff II, 
    101 Iowa L
    . Rev. at 1763 (citations omitted).
    Defendants are entitled to access the information needed to enforce
    their constitutional right to a jury trial by a representative cross-section
    of the community.       In this case, Plain attempted to obtain the
    information he is entitled to receive. Because our statutes do not specify
    a procedure for accessing the information, he took what we view to be a
    reasonable approach—he asked the jury manager to provide it. The jury
    manager did not produce the information, citing a lack of access to the
    information the state is constitutionally required to maintain.      To the
    extent Plain did not meet his prima facie case with respect to the third
    prong of the test, we conclude he lacked the opportunity to do so
    because he was not provided access to the records to which he was
    entitled.
    Because we find no reversible error on the other issues raised on
    appeal, we conditionally affirm Plain’s conviction and remand to the
    district court for development of the record on the Sixth Amendment
    challenge. Following proper development of the record pertaining to that
    39
    challenge, the district court shall determine whether Plain’s right to a
    representative jury under the Sixth Amendment was violated.           If the
    court concludes that right was violated, the court shall grant a new trial.
    IV. Disposition.
    We conclude that the district court’s admission of hearsay evidence
    through the testimony of an investigating officer about what caused the
    hole in the side of the house did not constitute reversible error because it
    was merely cumulative and thus not prejudicial. We further conclude
    the district court did not abuse its discretion in using a cautionary
    instruction to address a reference to Plain’s past criminal conduct on the
    911 tape. Although the district court’s denial of Plain’s request for an
    implicit-bias jury instruction rested upon an error of law and thus
    constituted an abuse of discretion, we conclude the denial did not
    prejudice Plain. Although the prosecutor committed error in repeatedly
    using the word “victim” to refer to the complainant in this case, we find
    no prejudicial error resulted.   Finally, we conclude the district court
    made an error of law in concluding the absolute disparity test must be
    used in deciding whether the jury pool was drawn from a fair cross-
    section of the community. We conditionally affirm Plain’s conviction and
    remand for development of the record on his Sixth Amendment
    challenge. On remand, the State shall provide the defendant reasonable
    access to the records necessary to evaluate whether African-Americans
    were systematically underrepresented in the jury pool from which the
    jurors were selected for Plain’s trial. Following development of the record
    on this issue, the district court shall reconsider Plain’s claim that his
    jury did not represent a fair cross-section of the community.
    AFFIRMED       ON     CONDITION        AND     REMANDED         WITH
    DIRECTIONS.

    CADY, Chief Justice (concurring specially).
    I concur in the majority opinion and join in the special
    concurrences by Justice Wiggins and Justice Appel.
    It is as important to address implicit bias in jury deliberations as it
    is to address racial diversity in jury selection. The more this is done, the
    more these biases and differences will cease to exist. The more this is
    done, the more the goal of a fair and impartial trial will be understood.
    Any verdict, judgment, or sentence motivated by any type of bias is
    unjust. Our system of justice must have confidence that the outcomes of
    trials were achieved with impartiality and fairness.       Today’s decision
    identifies several ways for our justice system to improve.       We should
    never stop looking for others.
    Wiggins and Appel, JJ., join this special concurrence.
    42
    #16–0061, State v. Plain
    WIGGINS, Justice (concurring specially).
    I join the majority opinion; however, I feel compelled to write
    separately on the issues of implicit bias and racial disparity in Iowa. A
    recent report by The Sentencing Project found 25.8% of Iowa’s prison
    population was black, while blacks made up only 3.1% of Iowa’s
    population.        Ashley Nellis, The Color of Justice: Racial and Ethnic
    Disparity in State Prisons 16 (2016) [hereinafter Nellis]. The same report
    found the black to white incarceration ratio in Iowa’s prisons was 11 to
    1. 
    Id. at 17.
    These statistics reveal that Iowa is one of the worst states
    in the country when it comes to racial disparity regarding imprisonment.
    
    Id. at 16–17.
    These numbers are shameful, and I believe much of the
    cause for these alarming statistics is due to implicit bias against blacks
    in Iowa.12
    I agree with the majority statement, “We strongly encourage
    district courts to be proactive about addressing implicit bias.”                     In
    furtherance of that encouragement, I would require judges to give an
    implicit-bias instruction in every case where counsel requests one and
    implicit bias may have an effect on a jury.
    Due    to    the   disgraceful    disparity    in   the    punishment       and
    incarceration between blacks and whites, we should not wait for further
    research and study on the issue of implicit bias and racial disparity. The
    demand for justice to our black citizens does not allow for further
    stalling. A defendant and his or her counsel are in the best position to
    12The same report finds the rates for Hispanic disparity are much different. In
    2014, 6.9% of Iowa’s prison population was Hispanic, while Hispanics made up 5.5% of
    Iowa’s population. Nellis, at 16. The same report found the Hispanic to white
    incarceration ratio in Iowa’s prisons was 1.7 to 1. 
    Id. at 17.
    Although the Hispanic to
    white disparity is better than the black to white disparity in Iowa, it could be better.

    know whether the circumstances of the present case warrant an implicit-
    bias instruction. A defendant and his or her counsel are also in the best
    position to determine whether instructing jurors on implicit bias may
    lead to a better outcome or not.
    In the future when a defendant requests an implicit-bias
    instruction and implicit bias may have an effect on a jury, there is no
    reason for the court not to instruct the jury on implicit bias. See Sonnek
    v. Warren, 
    522 N.W.2d 45
    , 47 (Iowa 1994).
    Cady, C.J., and Appel, J., join this special concurrence.

    #16–0061, State v. Plain
    APPEL, Justice (concurring specially).
    In this case, the court removes an inappropriate formalistic barrier
    to achieving increased representation of African-Americans and other
    minority groups on our juries by overturning precedent which, in my
    view, was plainly incorrect.      While this barrier-removing exercise is
    important, and even essential, we have a long way to go in ensuring
    fairness to racial minorities in our criminal justice system.
    I write separately to express my view that a criminal defendant is
    entitled to an accurate, properly worded implicit-bias jury instruction to
    assist the jury in reaching a fair and unbiased verdict.
    I. Overview of Implicit Bias.
    A. Introduction: What Are We Talking About?             What is this
    new-fangled “implicit bias” business all about?            Despite the new-
    sounding term, however, the concept of implicit biases is supported by
    long-standing theories of heuristics and cognitive biases.            Social
    scientists have long demonstrated that we tend to “anchor” our
    judgments about current perceptions in what we have experienced in the
    past.    See Thomas Mussweiler & Fritz Strack, Hypothesis-Consistent
    Testing and Semantic Priming in the Anchoring Paradigm: A Selective
    Accessibility Model, 35 J. Experimental Soc. Psychol. 136, 147 (1999)
    (describing the field of “heuristics and biases” and canvassing the
    literature, beginning in 1974, studying the anchoring effect).        Social
    scientists have identified an “endowment effect,” where we tend to give
    irrational attachment to initial distributions of property rights, grants, or
    other entitlements.     See Ying Zhang & Ayelet Fishbach, The Role of
    Anticipated Emotions in the Endowment Effect, 15 J. Consumer Psychol.
    316, 316 (2005). And, social scientists have observed “hindsight bias”
    45
    which makes us believe what happens today should have easily been
    foreseen.   See Jeffrey J. Rachlinski, A Positive Psychological Theory of
    Judging in Hindsight, 65 U. Chic. L. Rev. 571, 571–75 & n. 2–4 (1998)
    (describing the hindsight bias and citing to the psychological research).
    The National Center for State Courts has published a succinct
    description of implicit bias by a leading expert. Jerry Kang, Implicit Bias:
    A     Primer         for    Courts        1–6      (August     2009)        http://
    wp.jerrykang.net.s110363.gridserver.com/wp-content/uploads/2010/10
    /kang-Implicit-Bias-Primer-for-courts-09.pdf [hereinafter Kang, Implicit
    Primer]. In the Implicit Primer, Kang explains that all of us, in our daily
    lives, process information and develop “schemas,” or templates of
    knowledge that organize individual bits of information into more
    generalized concepts. 
    Id. at 1.
    Kang offers the following illustration of a schema: when a smiling
    person hands us a laminated paper with detailed descriptions of food
    and prices, we know what the gesture means. 
    Id. Kang explains
    that we
    categorize people in the same way. 
    Id. According to
    Kang, “We naturally
    assign people into various social categories divided by salient and
    chronologically accessible traits, such as age, gender, race, and role.” 
    Id. Many of
    these shorthand schemas may be unconscious, involving
    “implicit   social    cognitions   that    guide   our   thinking   about    social
    categories.” 
    Id. The notion
    of implicit bias has recently received considerable
    attention in the context of providing justice to African-American and
    other minority defendants in criminal trials. See Michelle Alexander, The
    New Jim Crow: Mass Incarceration in the Age of Colorblindness 106–08
    (2012). The general notion in the literature is that because of implicit
    bias, racial stereotyping may be unconscious and not explicit. In 2006,
    46
    the California Law Review published papers arising from symposia on
    implicit bias and behavioral realism with implications for the courtroom.
    See, e.g., R. Richard Banks et al., Discrimination and Implicit Bias in a
    Racially Unequal Society, 
    94 Cal. L
    . Rev. 1169, 1189–90 (2006); Anthony
    G. Greenwald & Linda Hamilton Krieger, Implicit Bias: Scientific
    Foundations, 
    94 Cal. L
    . Rev. 945, 965–67 (2006); Christine Jolls & Cass
    R. Sunstein, The Law of Implicit Bias, 
    94 Cal. L
    . Rev. 969, 995–96 (2006)
    [hereinafter Jolls]; Linda Hamilton Krieger & Susan T. Fiske, Behavioral
    Realism in Employment Discrimination Law: Implicit Bias and Disparate
    Treatment, 
    94 Cal. L
    . Rev. 997, 1061–62 (2006) [hereinafter Krieger,
    Behavioral Realism]. A review of implicit bias research and its potential
    application was conducted in a 2012 article coauthored by United States
    District Court Judge Mark Bennett. See Jerry Kang et al., Implicit Bias in
    the Courtroom, 59 UCLA L. Rev. 1124, 1128–34 (2012). A large body of
    academic literature has emerged on the subject. See, e.g., Mark W.
    Bennett, Unraveling the Gordian Knot of Implicit Bias in Jury Selection:
    The Problems of Judge-Dominated Voir Dire, The Failed Promise of Batson,
    and Proposed Solutions, 4 Harv. L. & Pol’y Rev. 149, 154–58 (2010)
    [hereinafter Bennett] (reviewing the literature); Jennifer S. Hunt, Race,
    Ethnicity, and Culture in Jury Decision Making, 11 Ann. Rev. L. & Soc.
    Sci. 269, 273–74 (2015); Jerry Kang & Kristin Lane, Seeing Through
    Colorblindness: Implicit Bias and the Law, 58 UCLA L. Rev. 465, 473–81
    (2010) [hereinafter Kang, Seeing Through Colorblindness] (summarizing
    the science).
    B. The Science Behind the Theory of Implicit Bias.              The
    leading approach documenting implicit bias is the Implicit Association
    Test (IAT). See Allen R. McConnell & Jill M. Leibold, Relations Among the
    Implicit Association Test, Discriminatory Behavior, and Explicit Measures
    47
    of Racial Attitudes, 37 J. Experimental Soc. Psychol. 435, 435 (2001).
    The IAT measures unconscious preferences by comparing the speed with
    which we make certain associations. See Anthony G. Greenwald et al.,
    Measuring Individual Differences in Implicit Cognition: The Implicit
    Association Test, 74 J. Personality & Soc. Psychol. 1464, 1464–65 (1998).
    Other kinds of measurements of implicit bias have also been developed.
    See 
    id. at 1477
    (describing the “evaluative priming method” as the chief
    method used to measure implicit biases prior to the IAT).          While a
    detailed summary of the research results are beyond the scope of this
    opinion, a substantial body of literature comes to the conclusion that
    implicit bias is substantial and real. See, e.g., David L. Faigman et al., A
    Matter of Fit: The Law of Discrimination and the Science of Implicit Bias,
    59 Hastings L.J. 1389, 1434 (2008); John T. Jost et al., The Existence of
    Implicit Bias Is Beyond Reasonable Doubt: A Refutation of Ideological and
    Methodological Objections and Executive Summary of Ten Studies that No
    Manager Should Ignore, 29 Res. Organizational Behav. 39, 41 (2000);
    Kang, Seeing Through Colorblindness, 58 UCLA L. Rev. at 519–20.
    C. Activities of American Bar Association and National Center
    for State Courts on Implicit Bias.
    1. American Bar Association.        The Section on Litigation of the
    American Bar Association has developed an “Achieving an Impartial Jury
    Toolbox” (AIJ Toolbox). Am. Bar Ass’n, Achieving an Impartial Jury (AIJ)
    Toolbox 1 (2015) [hereinafter AIJ Toolbox]. In this publication, the AIJ
    Toolbox notes there is more to discrimination than express bias, stating
    “research demonstrates that self-reports are often unreliable because we
    may not know our implicit biases and associations or we may not choose
    to reveal them.” 
    Id. at 8.
    The AIJ Toolbox further notes, “The workings
    and results of the IAT are widely documented.” 
    Id. at 9.
    The AIJ Toolbox
    48
    explains, “Using IAT data, researchers have found pervasive implicit bias
    in associations in favor of Whites as compared to Blacks, women in
    families as compared to women in careers, and the abled as compared to
    the disabled.” 
    Id. (footnotes omitted).
    The AIJ Toolbox goes on to state
    “[w]hile these implicit associations are made without our express
    knowledge, and often contrary to or honestly held beliefs, they
    nevertheless influence our responses and decisions.” 
    Id. at 10
    (footnotes
    omitted).
    The AIJ Toolbox includes an instruction on implicit bias. 
    Id. at 17–
    20.   The AIJ Toolbox concedes that arriving at the language was
    challenging and that fundamental questions were raised whether
    highlighting the notion of implicit bias would do more harm than good.
    
    Id. at 16.
    In addition to its own draft instruction, the AIJ Toolbox also
    presents the implicit-bias instruction used by Judge Bennett, a
    California jury instruction, and a race-switching instruction developed by
    Professor Cynthia Lee. 
    Id. at 20–22.
    2. National Center for State Courts. The National Center for State
    Courts (NCSC) has also been active in the field of implicit bias. Although
    publication does not imply endorsement, the NCSC funded and
    published a summary on implicit bias by Jerry Kang. See Kang, Implicit
    Primer, at 1.    The NCSC also has published a study of implicit-bias
    instructions. See Jennifer K. Elek & Paula Hannaford-Agor, Nat’l Ctr. for
    State Cts., Can Explicit Instructions Reduce Expressions of Implicit Bias:
    New Questions Following a Test of Specialized Jury Instruction 2 (April
    2014).      The study found no significant effects of an implicit-bias
    instruction    on   judgments   of   guilt,   confidence,     strength   of   the
    prosecution’s evidence, or sentence length.       
    Id. at 3.
       As a result, the
    49
    researchers were unable to render a verdict on the utility of a specialized
    jury instruction. 
    Id. D. Judicial
    Acceptance of Implicit-Bias Theory. Although the
    United States Supreme Court has not expressly embraced the theory of
    implicit bias, various members of the court have done so. For instance,
    Justice Ginsburg in Grutter v. Bollinger has noted, “It is well documented
    that conscious and unconscious race bias . . . remain[s] alive in our land,
    impeding realization of our highest values and ideals.”     
    539 U.S. 306
    ,
    345, 
    123 S. Ct. 2325
    , 2347–48 (2003) (Ginsburg, J., concurring).
    Similarly, Justice O’Connor in Georgia v. McCollum wrote, “It is by now
    clear that conscious and unconscious racism can affect the way white
    jurors perceive minority defendants and the facts presented at their
    trials, perhaps determining the verdict of guilt or innocence.” 
    505 U.S. 42
    , 68, 
    112 S. Ct. 2348
    , 2364 (1992) (O’Connor, J., dissenting). Justice
    White also observed in Turner v. Murray that “[m]ore subtle, less
    consciously held racial attitudes could also influence a juror’s decision in
    this case.” 
    476 U.S. 28
    , 35, 
    106 S. Ct. 1683
    , 1688 (1986). In his dissent
    in Turner, Justice Brennan declared it to be “incontestable that
    subconscious, as well as express, racial fears and hatreds operate to
    deny fairness to the person despised.”      
    Id. at 42,
    106 S. Ct. at 1691
    (Brennan, J., dissenting)
    We have also recognized the reality of implicit bias. In Pippen v.
    State, this court considered whether plaintiffs could bring a class action
    under Title VII and the Iowa Civil Rights Act against thirty-seven different
    executive branch departments as a result of disparate hiring practices.
    
    854 N.W.2d 1
    , 5 (2014).      Among other evidence, the plaintiff offered
    expert testimony from Anthony Greenwald and Cheryl Kaiser, leading
    experts on implicit bias. 
    Id. at 6.
    The majority opinion held that under
    50
    applicable law, a class action across thirty-seven departments could not
    be maintained. 
    Id. at 32.
    Importantly, in a concurring opinion, Justice
    Waterman wrote, “Implicit-bias theory helps explain how statistical
    disparities can result without intentional discrimination.”        
    Id. at 33
    (Waterman, J., concurring specially).     He further wrote that “there
    undoubtedly    was    subjectivity   and—as     the   plaintiffs    credibly
    demonstrated—implicit bias in multiple State hiring decisions.”       
    Id. at 41.
      Nothing in the Pippen majority opinion contradicted Justice
    Waterman’s observations.
    II. Instructions to Jury as Remedy for Implicit Bias.
    A. Introduction.     One potential remedy in a jury trial is a jury
    instruction that accurately describes the potential problem of implicit
    bias and properly instructs the jurors of the need to avoid making a
    decision based upon it. We have stated a defendant is entitled to a jury
    instruction that is germane to the case and accurately states the law.
    Alcala v. Marriott Int’l, Inc., 
    880 N.W.2d 699
    , 707 (Iowa 2016);
    Weyerhaeuser Co. v. Thermogas Co., 
    620 N.W.2d 819
    , 823–24 (Iowa
    2000); Sonnek v. Warren, 
    522 N.W.2d 45
    , 47 (Iowa 1994). While we have
    also stated the failure to give a cautionary instruction is reviewed for
    abuse of discretion, State v. Webb, 
    516 N.W.2d 824
    , 831 (Iowa 1994),
    implicit bias is so pervasive and the harm from implicit bias so difficult
    to prove in a particular case that I conclude a criminal defendant is
    entitled to an implicit-bias instruction upon request. Examples of jury
    instructions provided in the AIJ Toolbox include the AIJ model
    instruction, the instruction utilized by Judge Bennet, an implicit-bias
    instruction from California, and a race-switching instruction suggested
    by Professor Lee. See AIJ Toolbox at 17–22.
    51
    B. Rationale for Implicit-Bias Instruction. The rationale for an
    implicit-bias instruction is that it is consistent with the way the human
    mind works and is an appropriate remedy to minimize the impact of
    implicit bias in jury determinations. Research suggests that the problem
    of implicit bias may be moderated by attention to the issue. See Irene V.
    Blair, The Malleability of Automatic Stereotypes and Prejudice, 6
    Personality & Soc. Psychol. Rev. 242, 255 (2002) (“[R]esults of these tests
    show that automatic stereotypes and prejudice can be moderated by a
    wide variety of events . . . .”); Anna Roberts, (Re)Forming the Jury:
    Detection and Disinfection of Implicit Juror Bias, 
    44 Conn. L
    . Rev. 827,
    835 (2012) (noting that IAT researches find implicit associations
    “malleable”).
    C. Objections to Implicit-Bias Jury Instruction.
    1. Rejection of social science in favor of formalistic legal structures.
    One potential objection is that courts should not look to social science in
    the development of law generally, but should instead rely on formalistic
    legal structures that have historically been applied by the legal system.
    Although historically embraced approaches to law have undoubted value,
    the law must be rooted in reality. Scientific developments should affect
    legal doctrine. For instance, evolving science has significantly affected
    this court’s approach to the application of the Iowa Constitution’s cruel
    and unusual punishment clause with respect to juveniles.           See, e.g.,
    State v. Sweet, 
    879 N.W.2d 811
    , 839 (Iowa 2016); State v. Ragland, 
    836 N.W.2d 107
    , 115 (Iowa 2013); State v. Null, 
    836 N.W.2d 41
    , 74 (Iowa
    2013). Similarly, as shown in the seminal case of State v. Henderson, the
    law of eyewitness identification is being reevaluated in light of evolving
    science that challenges broad-brush, undifferentiated views on the
    reliability of eyewitness identifications. 
    27 A.3d 872
    , 917 (N.J. 2011).
    52
    2. Not supported by social science research. Another approach is
    to attack the underlying scientific basis of a jury instruction for implicit
    bias. This challenge breaks down into two questions. First, is there a
    scientific basis for implicit bias generally? Second, if there is, has it been
    scientifically demonstrated that a proposed jury instruction is an
    appropriate and effective remedy?
    On the first question, I conclude that there is strong scientific
    evidence of the existence of implicit bias. Whether an instruction will be
    effective is another question.    Unlike the question of whether implicit
    bias exists, where there is a large literature, there is not a body of science
    demonstrating the impact of an implicit-bias instruction on a jury and, to
    the extent it exists, it appears inconclusive. See AIJ Toolbox, at 15 n.20.
    But a body of social science evidence demonstrating utility is not
    required of our jury instructions. The instructions of the Iowa State Bar
    Association, for example, have not been subjected to social science
    analysis for their likely impact as have, for instance, questions on the bar
    examination developed by the National Conference of Bar Examiners.
    Instead of requiring social science confirmation, we allow various
    wordings of legal concepts in jury instructions if they accurately reflect
    the law. If a body of social science research supporting the efficacy of
    each jury instruction were required, we would have no approved jury
    instructions and no judge could craft his or her own case-specific
    instructions without social science support.
    3. Inflaming jurors against defendant.      The concern is expressed
    that an implicit-bias jury instruction could potentially inflame jurors.
    This concern may be put in the “anything is possible” file.          There is
    certainly no social science support for that proposition. In any event, it
    is certainly equally possible, and probably more likely, that a jury
    53
    instruction on the presumption of innocence would well inflame a juror
    who believes that the criminal justice system affords too many rights to
    criminal defendants and is too lenient. It is ironic to deny a defendant
    an accurate instruction on implicit racial bias sought by the defendant’s
    lawyer on the ground that, in some conceivable scenarios, it might,
    perhaps, maybe, be counterproductive on particular jurors.
    In any event, we ordinarily leave it up the defendant’s counsel to
    make the determination as to whether his client will benefit from a
    particular instruction.     See Lamphere v. State, 
    348 N.W.2d 212
    , 217
    (Iowa 1984) (holding that counsel is not ineffective for failing to request
    every legally supportable jury instruction).         There is no mandatory
    requirement that a lawyer seek an instruction to which the defendant is
    entitled but which, in the lawyer’s professional judgment, may do more
    harm than good. It is fundamental to our adversary system, however,
    that defendant’s counsel, and not the court, make that strategic decision.
    4. The problem of overcorrection. Another possible objection is the
    fear   that    an   implicit-bias   instruction   could   potentially   lead   to
    overcorrection. The potential of overcorrection, however, inheres in many
    jury instructions. That said, a properly worded implicit-bias instruction
    should minimize the risks of overcorrection by emphasizing that the
    jury’s decision should be based on facts and evidence and not on
    stereotypes.    Further, as noted by Professor Lee, “until there is some
    tangible evidence that making race salient would lead jurors to
    overcorrect in racially unjust ways, it seems imprudent not to even
    attempt to deal with the racial bias we know exists.”             Cynthia Lee,
    Making Race Salient: Trayvon Martin and Implicit Bias in a Not Yet Post-
    Racial Society, 
    91 N.C. L
    . Rev. 1556, 1608 (2013).
    54
    D. Use of an Implicit-Bias Instruction in This Case.          I agree
    with the basic premise that our law should be based on a realistic
    understanding of human behavior. See Jolls, 
    94 Cal. L
    . Rev. at 995. As
    noted by Oliver Wendell Holmes many years ago, “The first call of a
    theory of law is that it should fit the facts.” Krieger, Behavioral Realism,
    
    94 Cal. L
    . Rev. at 997 (quoting Oliver Wendell Holmes, The Common Law
    167 (1963)). I am also convinced that implicit bias is real, pervasive, and
    potentially outcome determinative in a criminal trial.    I further believe
    that other remedies, such as the remedy theoretically available under
    Batson v. Kentucky, 
    476 U.S. 79
    , 93–98, 
    106 S. Ct. 1712
    , 1721–24
    (1986), are ineffective. See Bennett, 4 Harv. L. & Pol’y Rev. at 161–68;
    Antony Page, Batson’s Blind Spot: Unconscious Stereotyping and the
    Peremptory Challenge, 85 B.U. L. Rev. 155, 178–79 (2005) (characterizing
    Batson as ineffective).   Courts should not get unduly stressed when
    presented with an accurate instruction designed to address a real and
    persistent problem.
    As a result, I conclude that a criminal defendant is entitled to an
    accurate, appropriately worded implicit-bias instruction upon request.
    In my view, the other instructions in this case did not adequately
    address the problem of implicit bias. Ideally, such an instruction should
    be given at the beginning of jury selection.      I would not dictate the
    specific working of an implicit-bias jury instruction, but the model
    instruction of the ABA, Judge Bennett’s instruction, and the implicit-bias
    instruction in the District of Columbia and California provide meaningful
    guidance. See AIJ Toolbox, at 17–22.
    55
    I acknowledge this step would be a departure from current law.13
    It was not long ago, however, when even express racial discrimination
    was permitted in courtrooms all across the country.                   An implied-bias
    instruction is not innovation for the sake of innovation, but reflects a
    reassessment of courtroom conduct based on evolving science and the
    aspiration of achieving fundamental fairness that is indispensable to our
    system of justice.        Refined efforts to achieve fairness are not only
    important to the participants in trials but to public confidence in our
    system of justice.
    There is, of course, a question of timing.                  There always is a
    question of timing.       Every substantive change may be resisted by the
    refrain “not now, but later.” Later, of course, often explicitly or implicitly
    13The   few cases from other jurisdictions I have found that have directly
    addressed an implicit-bias instruction, as opposed to a more general racial-bias
    instruction, have determined that the giving of such an instruction is within the
    discretion of the district court judge. See United States v. Graham, ___ Fed. App’x ___,
    ___, 
    2017 WL 702287
    , at *3 (8th Cir. Feb. 22, 2017) (per curiam); State v. Roseboro, 
    528 S.E.2d 1
    , 13 (N.C. 2000). These cases are not germane under Iowa law because Iowa
    employs a different substantive standard than federal law to determine whether a party
    is entitled to an instruction. In Graham, the United States Court of Appeals for the
    Eighth Circuit stated that jury instructions must fairly inform the jury “of the essential
    elements of the offense charged, as well as the government’s burden of proof.” ___ Fed.
    App’x at ___, 
    2017 WL 702287
    , at *3. Under Iowa law, a defendant is entitled to the
    submission of a jury instruction if it “correctly states the applicable law and is not
    embodied in other instructions.” 
    Sonnek, 522 N.W.2d at 47
    . We have no requirement
    that a proposed jury instruction must relate to an essential element of the offense, or
    the government’s burden of proof, in order to reverse for failure to give a jury
    instruction.
    The question in Roseboro was whether a capital murder defendant was
    constitutionally entitled to an instruction for the jury to disregard explicit and implicit
    racial biases in the penalty phase of the trial. 
    Id. at 554.
    Here, we are not dealing with
    the question of whether due process requires an implicit-bias instruction, so the
    Supreme Court of North Carolina’s holding may not be applicable. Additionally, there is
    no evidence that the Roseboro court considered the research on how racial bias
    pervasively infects an imposition of the death penalty when the defendant is African-
    American and the victim is Caucasian. It seems unlikely that the North Carolina court
    did consider this research because it wrote that the defendant’s proposed instructions
    would “in effect, inject[] racial bias into the jurors’ consideration.” 
    Id. at 555.
                                        56
    means never. For me, in light of the large body of science demonstrating
    implicit bias, the time for an implicit-bias instruction in Iowa courtrooms
    is now.
    Cady, C.J., and Wiggins, J., join this special concurrence.
    57
    #16–0061, State v. Plain
    WATERMAN, Justice (concurring specially).
    I join the majority’s well-reasoned opinion except for Part III.D.2,
    addressing the prosecutor’s use of the word “victim” in her closing
    argument.     On that issue, I join the special concurrence of Justice
    Mansfield. I write separately to respond to the special concurrences of
    Justice Wiggins and Justice Appel that would require judges to give a
    jury instruction on implicit bias. Although I might decide to use such an
    instruction if I were a trial judge, I do not believe our court has enough
    information at this point to mandate such an instruction statewide
    whenever there is a defendant from a racial minority. Furthermore, no
    cases have been cited to us requiring trial courts to instruct on implicit
    bias.    To date, all appellate courts addressing the question have
    confirmed that trial courts have discretion whether to instruct the jury
    on racial bias. I agree with our court’s majority that the district court
    had discretion whether to give the implicit-racial-bias instruction, and
    the omission of that instruction did not prejudice Kelvin Plain.
    Just this year, the United States Court of Appeals for the Eighth
    Circuit held that a trial court was not required to instruct on implicit
    racial bias in a criminal case. United States v. Graham, ___ F. App’x ___,
    
    2017 WL 702287
    , at *3 (8th Cir. Feb. 22, 2017) (per curiam). The jury
    convicted Fredrick Graham of being a felon in possession of a firearm.
    
    Id. at *1.
      He offered a proposed instruction to “counteract the jurors’
    ‘implicit bias’ and ‘unconscious racial attitudes.’ ”   
    Id. at *2.
      Like the
    instruction requested by Plain, Graham’s instruction “directed the jurors
    to reach their verdict ‘without discrimination’ and without ‘consider[ing
    Graham’s] race, color, religious beliefs, national origin, or sex.’ ”     
    Id. 58 (alteration
    in original). The trial court declined to give the instruction,
    and the Eighth Circuit affirmed, stating,
    Graham next argues that the district court abused its
    discretion by declining to give his proposed instruction on
    implicit racial bias. We disagree. A district court has broad
    discretion to formulate jury instructions. We review jury
    instructions as a whole and affirm if they “fairly and
    adequately submitted the issues to the jury.” The district
    court’s instructions fairly informed the jury of the essential
    elements of the offense charged, as well as of the
    government’s burden of proof. Additionally, the instructions
    specifically directed the jury that it should “not allow
    sympathy or prejudice to influence you. The law demands of
    you a just verdict, unaffected by anything except the
    evidence, your common sense, and the law as I give it to
    you.” The district court did not abuse its discretion by
    declining to give Graham’s proposed instruction.
    
    Id. at *3
    (citations omitted) (quoting United States v. Farish, 
    535 F.3d 815
    , 821 (8th Cir. 2008)).
    Every other appellate court to reach the question has ruled
    similarly: trial courts have discretion to grant or to decline a party’s
    request to instruct the jury on racial bias.   See United States v. Díaz-
    Arias, 
    717 F.3d 1
    , 23 (1st Cir. 2013) (concluding court’s instruction to be
    “fair-minded   and   impartial”   encompassed     defendant’s    requested
    instruction on racial prejudice); People v. Williams, 
    384 P.3d 1162
    , 1187
    (Cal. 2016) (holding “trial court did not err when it refused to give
    defendant’s requested instruction” to disregard race); People v. Smith, 
    68 P.3d 302
    , 341 (Cal. 2003) (noting court did not err in refusing to
    “instruct the jury to disregard his and the victim’s racial backgrounds”);
    State v. Roseboro, 
    528 S.E.2d 1
    , 13 (N.C. 2000) (“[T]he trial court was not
    required to instruct the jurors that they should avoid giving any
    consideration to racial factors . . . .”); State v. Richardson, 
    467 S.E.2d 685
    , 696 (N.C. 1996) (concluding defendant’s rights had not been
    violated when district court refused to give proposed instruction on racial
    59
    bias); see also Jahagirdar v. United States, 
    597 F. Supp. 2d 198
    , 204 (D.
    Mass. 2009) (concluding defense counsel not unreasonable in failing to
    request racial-bias instruction because it “might unnecessarily draw
    attention to the racial differences between the defendant and the alleged
    victim”).
    In Smith, the defendant, an African-American man, was convicted
    of kidnapping, raping, and murdering a female Japanese exchange
    
    student. 68 P.3d at 312
    –13. He requested an instruction that the jury
    was to “disregard his and the victim’s racial backgrounds” in its death
    penalty determination.      
    Id. at 341.
        The California Supreme Court
    affirmed the district court’s refusal to give that instruction, stating,
    [T]he instruction is not constitutionally required. Obviously,
    the jury may not consider the defendant’s or victim’s race in
    deciding whether to impose the death penalty. . . . But the
    court need not interject the issue of race itself and then tell
    the jury to disregard it, at least absent some indication the
    jury might improperly consider race.
    
    Id. (citation omitted).
    The North Carolina Supreme Court similarly held
    the trial court was not required to give an implicit-bias instruction,
    noting the proposed instruction would “in effect, inject[] racial bias into
    the jurors’ consideration of defendant’s sentence and divert[] their
    attention away from the more pertinent issues of defendant’s character
    and the circumstances of the crime.” 
    Roseboro, 528 S.E.2d at 13
    . In
    Love v. State, our court of appeals observed,
    No clear right or wrong approach to handling the issue of
    racial bias exists and even the need for courts and lawyers to
    consider this issue can be as troubling as the issue itself. It
    can project disturbing overtones when injected into the trial
    proceedings due to the subtle impression that justice in a
    court of law in this country may turn upon skin color.
    
    543 N.W.2d 621
    , 624 (Iowa Ct. App. 1995).
    60
    In Díaz-Arias, the district court refused to provide the jury with an
    instruction stating that it would be improper to consider “any personal
    feelings you may have about the defendant’s race or ethnicity, or national
    origin, or his or any witness’ immigration 
    status.” 717 F.3d at 22
    .
    Instead, the district court instructed that the jury should be “completely
    fair-minded and impartial, swayed neither by prejudice, nor sympathy,
    by personal likes or dislikes toward anybody involved.” 
    Id. at 23.
    The
    First Circuit affirmed, concluding “Díaz-Arias’ proposed instruction was a
    more specific version of the court’s instruction; it merely recited the
    possible forms of prejudice that a person might have . . . . The court’s
    instructions effectively incorporated the essence of Díaz-Arias’ request.”
    
    Id. I reach
    the same conclusion here. Iowa jury instructions are to be
    read as a whole. Rivera v. Woodward Res. Ctr., 
    865 N.W.2d 887
    , 902
    (Iowa 2015). The instructions to Plain’s jury made clear the verdict was
    to be based solely on the evidence. The concept that race should play no
    role in the verdict was thereby embodied in the instructions read as a
    whole. The jury instructions stated,
    You shall base your verdict only upon the evidence
    and these instructions.
    Evidence is:
    1. Testimony in person or
    2. Exhibits received by the Court. You may examine
    the exhibits closely, but be careful not to alter or destroy
    them.
    3. Stipulations entered into by the parties.
    Jurors were instructed to “decide the facts from the evidence” and
    determine witness credibility based on race-neutral criteria, such as
    “whether testimony [was] reasonable and consistent with other evidence,”
    “whether . . . witness[es] ha[d] made inconsistent statements,” witness
    61
    “appearance, conduct, age, intelligence, memory, and knowledge of the
    facts,” and the witness’s “interest in the trial, their motive, candor, bias,
    and prejudice.” The instructions told the jury the defendant was to be
    presumed “innocent and not guilty” and that jurors must “put aside all
    suspicion which might arise from the arrest, charge, or the present
    situation of the defendant.” The jury was further instructed to decide the
    case based on its “impartial consideration of the evidence.” Finally, the
    instructions stated, “Remember, you are the judges of the facts. Your
    sole duty is to find the truth and do justice.”
    We presume the jury follows the court’s instructions.         State v.
    Haines, 
    790 N.W.2d 545
    , 552 (Iowa 2010). As the Supreme Court has
    stated, “[T]here is no constitutional presumption of juror bias for or
    against members of any particular racial or ethnic groups.”         Rosales-
    Lopez v. United States, 
    451 U.S. 182
    , 190, 
    101 S. Ct. 1629
    , 1635 (1981).
    I do not question the proposition that all of us in the judicial
    system—including judges, jurors, and attorneys—are subject to many
    different forms of implicit bias. Racial bias may be the most persistent
    form of implicit bias. But it is one thing to say that implicit bias is a
    problem.   It is another thing to mandate a special jury instruction on
    implicit bias as the designated solution to that problem.       In my view,
    more research is needed before we substitute our judgment concerning
    such an instruction for that of our trial judges.           Justice Appel’s
    concurrence cites “strong scientific evidence of the existence of implicit
    bias” but, at the same time, dismisses the need for “social science
    evidence demonstrating utility” of an implicit-bias jury instruction. That
    reasoning is incongruous. We do not look for social science to prove the
    efficacy of jury instructions that simply set forth the applicable law or
    elements or a claim or defense. But when social science is the basis for a
    62
    jury instruction, as it would be for one on implicit bias, some degree of
    social science support for the instruction is required. Yet no empirical
    study has been cited that an implicit-bias jury instruction improves juror
    decision-making. That dearth of support gives me pause.
    The district court noted the absence of a uniform jury instruction
    on implicit racial bias. 14      United States District Court Judge Mark W.
    14Plain’s
    jury trial was in October 2015. The following June, the Iowa State Bar
    Association Jury Instruction Committee proposed changes to Uniform Criminal Jury
    Instruction 100.8 to include language concerning juror biases. The instruction now
    reads,
    100.8 Consideration of Instructions. You must determine
    whether the defendant is guilty or not guilty from the evidence and the
    law in these instructions. My duty is to tell you what the law is. Your
    duty is to accept and apply this law and to decide all fact questions.
    You must consider all of the instructions together.         No one
    instruction includes all of the applicable law.
    As you consider the evidence, do not be influenced by any
    personal sympathy, bias, prejudices or emotions. Because you are
    making very important decisions in this case, you are to evaluate the
    evidence carefully and avoid decisions based on generalizations, gut
    feelings, prejudices, sympathies, stereotypes, or biases.    The law
    demands that you return a just verdict, based solely on the evidence,
    your reason and common sense, and these instructions. As jurors, your
    sole duty is to find the truth and do justice.
    Iowa State Bar Ass’n, Iowa Criminal Jury Instruction 100.8 (2016). A similar change
    was made to Uniform Civil Jury Instruction 100.2 which now reads,
    100.2 Duties of Judge and Jury, Instructions as Whole. My
    duty is to tell you what the law is. Your duty is to accept and apply this
    law.
    You must consider all of the instructions together because no one
    instruction includes all of the applicable law.
    The order in which I give these instructions is not important.
    Your duty is to decide all fact questions.
    As you consider the evidence, do not be influenced by any
    personal sympathy, bias, prejudices or emotions. Because you are
    making very important decisions in this case, you are to evaluate the
    evidence carefully and avoid decisions based on generalizations, gut
    feelings, prejudices, sympathies, stereotypes, or biases.    The law
    demands that you return a just verdict, based solely on the evidence,
    63
    Bennett has thoroughly studied ways to address implicit biases and uses
    this jury instruction before opening statements in all his civil and
    criminal trials:
    As we discussed in jury selection, growing scientific research
    indicates each one of us has “implicit biases,” or hidden
    feelings, perceptions, fears and stereotypes in our
    subconscious. These hidden thoughts often impact how we
    remember what we see and hear and how we make
    important decisions. While it is difficult to control one’s
    subconscious thoughts, being aware of these hidden biases
    can help counteract them.         As a result, I ask you to
    recognize that all of us may be affected by implicit biases in
    the decisions that we make. Because you are making very
    important decisions in this case, I strongly encourage you to
    critically evaluate the evidence and resist any urge to reach a
    verdict influenced by stereotypes, generalizations, or implicit
    biases.

    As Justice Appel concedes, the studies are inconclusive.                One
    scholar cautioned that “instructing jurors to ignore the defendant’s race
    might exacerbate the effect of race upon guilt attribution.” Sheri Lynn

    investigate the effects of jury instructions failed to demonstrate any
    significant influence on jurors’ verdict preferences. Jennifer K. Elek &

    implicit bias had “no significant effects . . . on judgments of guilt,
    confidence, strength of the prosecution’s evidence, or sentence length”).
    In 2015, the American Bar Association began a project with the
    intent of developing a jury instruction on implicit             bias as its
    “centerpiece.” Am. Bar Ass’n, Achieving an Impartial Jury (AIJ) Toolbox
    15 (2015) [hereinafter AIJ Toolbox].        However, it ultimately concluded
    that “the drafting of such language was challenging” and “fundamental
    questions were raised as to whether a judge’s highlighting of the notion
    of implicit bias would do more harm than good.” 
    Id. In the
    end, the ABA
    simply offered a “toolbox,” that is, “a variety of approaches . . . as
    possibilities for judges desiring to use this kind of instruction.” 
    Id. at 16.
    In other words, far from mandating any particular instruction, as the
    special concurrences would, the ABA supports leaving the matter to
    individual judges. I agree.
    To illustrate the lack of consensus as to content and timing even
    among the supporters of a mandatory instruction, consider the present
    case. Here, defense counsel asked for an instruction after the close of
    evidence that directly mentions race, while Justice Appel’s special
    concurrence would require some instruction to be given during jury
    66
    selection, and Judge Bennett gives his instruction, which does not
    mention race, before opening statements. See Bennett, 4 Harv. L. & Pol’y
    Rev. at 169 n.85.
    We have required all Iowa judges to undergo implicit-bias training
    and testing. But I would not require courts to give an implicit-bias jury
    instruction without further research and study.       For now, like the
    majority, I leave it to the trial judge’s discretion whether to instruct
    separately on implicit bias.
    Mansfield and Zager, JJ., join this special concurrence.
    67
    #16–0061, State v. Plain
    MANSFIELD, Justice (concurring specially).
    I generally agree with the court’s well-reasoned opinion, but write
    separately to raise one area of disagreement.
    In Part III.D.1, the court concludes that “the prosecutor erred
    during closing argument in persistently using the term ‘victim’ to refer to
    the complaining witness.”     This is dictum, because in Part III.D.2 the
    court goes on to find no prejudice from the prosecutorial error.         The
    court could have omitted Part III.D.1 and simply have assumed an error
    occurred for purposes of its opinion.      However, because the court has
    seemingly established a new rule for closing arguments in criminal cases
    in Iowa, I want to register a different view.
    I think whether prosecutors can use the term “victim” in closing
    argument should be left to the individual judgment of trial judges
    running their own courtrooms. This is not an area in need of a statewide
    rule promulgated by the Iowa Supreme Court.
    Here the prosecutor chose to use the terms “defendant” and
    “victim” instead of actual names during closing argument.           After the
    nineteenth use of the term “victim,” defense counsel objected: “Your
    Honor, I’m objecting to the State’s repeated reference to Mr. Gray as the
    victim in this case. It’s the jury’s decision.” At this point, the district
    court overruled the objection. The prosecutor continued to use the term.
    No further objection was made.
    Note defense counsel’s objection.         She didn’t complain that the
    prosecutor was going outside the bounds of fair argument. Instead she
    said, “It’s the jury’s decision.” Experienced lawyers make these kinds of
    objections not because they expect to be upheld by the trial judge, but
    because they want to make sure the jury understands what is going on—
    68
    i.e., an opponent’s repetitive and even ham-handed use of a rhetorical
    device. The objection does the job whether or not it is sustained by the
    district court.
    Policing this stuff ought to be the job of our trial courts, not us. I
    would have no problem with a trial court that forbid the use of the term
    “victim” in closing argument. Such a ruling would eliminate a potentially
    loaded term and would not deprive the prosecutor of the ability to
    vigorously argue the evidence. I also would have no problem with a trial
    court that allowed use of the term “victim”.          It is, after all, an
    extrapolation from the evidence. Additionally, if overused, the term can
    become tiresome and counterproductive.          Further, as I’ve already
    explained, experienced defense lawyers have ways of defusing this sort of
    thing, if it needs to be defused.
    My concern arises when we turn this type of matter into a serious
    appellate issue. The court correctly says that context matters when it
    comes to use of the term “victim.” But it then proceeds to blur context in
    its analysis. There is a difference, of course, between a court’s use of the
    term in jury instructions and a prosecutor’s use of the term in closing
    argument. See, e.g., Talkington v. State, 
    682 S.W.2d 674
    , 674 (Tex. Ct.
    App. 1984) (“The court, in its charge, referred to the complainant as the
    ‘victim.’ ”). Argument is, after all, argument. As in other jury trials, the
    jury in this case was instructed that the closing arguments of counsel
    are not themselves evidence.        So I would focus on closing argument
    precedents.
    Here, appellate court viewpoints diverge, although I have yet to find
    a conviction being reversed because the prosecutor used the word
    “victim” in closing argument. See State v. Warholic, 
    897 A.2d 569
    , 584
    (Conn. 2006) (concluding it was not improper for the State to refer to the
    69
    complainant as the victim during its closing remarks because “the jury
    was likely to understand that the state’s identification of the complainant
    as the victim reflected the state’s contention that, based on the state’s
    evidence, the complainant was the victim of the alleged crimes”); State v.
    Albino, 
    24 A.3d 602
    , 617, 626 (Conn. App. Ct. 2011) (finding that the
    prosecutor’s   twenty-seven   references   to   “the   victim”   during   the
    evidentiary phase of the trial, combined with use of the term throughout
    closing argument, was improper but not prejudicial such as to warrant a
    new trial).
    Some appellate courts have stated that the term “victim” during
    closing argument is not objectionable. See United States v. Gibson, 
    690 F.2d 697
    , 703 (9th Cir. 1982) (“[T]he prosecutor’s use of the word ‘victim’
    was fair comment on the evidence.”); People v. Shendi, No. C064289,
    
    2011 WL 521173
    , at *5 (Cal. Ct. App. Feb. 15, 2011) (“[T]he prosecutor’s
    characterization of Galindo was not improper because it was based on
    evidence within the record. Indeed, the fact that the prosecution charged
    defendant necessarily implies the prosecutor believed him to be guilty
    and believed that Galindo was the ‘victim’ of defendant’s crime.”); People
    v. Lampe, No. 326660, 
    2016 WL 3452161
    , at *7 (Mich. Ct. App. June 23,
    2016) (finding no misconduct in prosecutor’s use of the term forty-eight
    times during closing argument because “victim” does not necessarily
    mean victim of a crime).
    To my mind, this body of precedent confirms that we should not be
    devoting appellate resources to this issue. Instead, we should be leaving
    supervision where it has been until now—in the hands of our able trial
    judges.
    Consistent with this approach, when a particular closing argument
    passes trial judge scrutiny and reaches us on appeal, we have said that a
    70
    prosecutor has “considerable latitude.” State v. Carey, 
    709 N.W.2d 547
    ,
    555 (Iowa 2006). In effect, this means the lawyer “may draw conclusions
    and argue permissible inferences which reasonably flow from the
    evidence presented.” 
    Id. at 554
    (quoting State v. Thornton, 
    498 N.W.2d 670
    , 676 (Iowa 1993)). In Carey, we found no error when the prosecutor
    implied during closing argument that the defendant would have
    assaulted a police officer if only he had a knife, that the defendant
    should have sent a threatening letter to a witness in order to save his
    case, and then asked the jury whether the defendant was playing
    “games” with them due to his inconsistent testimony. 
    Id. at 555.
    We
    said that the comments, “while sarcastic and snide, were based on a
    legitimate assessment of the evidence.” 
    Id. Carey is
    a much closer case.
    Moreover, the record in this case shows that the prosecutor made
    no reference to Randy Gray as the victim until after the jury had heard
    his testimony in full. In her opening statement, the prosecutor used the
    terms “Mr. Gray” and “Mr. Plain” to identify the principals. Only after
    Gray’s testimony did she substitute the terms “victim” and “defendant” in
    the closing.
    One final note. A legitimate concern has been expressed that our
    legal culture has been too willing to devictimize crimes, particularly
    crimes of sexual violence.      See Claudia Bayliff, Project Attorney, Nat’l
    Judicial Educ. Program, Legal Momentum, Presentation at the Iowa
    Judges Fall Conference: Raped or “Seduced”?         How Language Impacts
    Perceptions of Sexual Violence (Oct. 28, 2015) (expressing the need to
    “[r]eclaim ‘victim’ ”).   In a criminal case of sexual assault, some have
    stated the view that “the term ‘victim’ will typically be used,” and “the
    phase ‘alleged victim’ . . . must be justified by unique circumstances.”
    
    Id. (resource materials
    at 27). This further highlights the need for trial
    71
    judge discretion rather than supreme court across-the-board decisional
    rulemaking.
    For these reasons, I concur except as to Part III.D.1 of the court’s
    opinion.
    Waterman, J., joins this special concurrence.
