    SUMMARY*
    Habeas Corpus/Death Penalty
    The panel affirmed the district court’s denial of Richard
    Delmer Boyer’s habeas corpus petition challenging his two
    first degree murder convictions and death sentence.
    The panel held that the state court did not unreasonably
    apply clearly established Supreme Court precedent when it
    determined that federal law did not require the trial court to
    conduct a live evidentiary hearing to assess the reliability of
    testimony that the prosecution introduced at the penalty phase
    in order to prove that Boyer had committed a prior murder.
    Regarding Boyer’s sufficiency of the evidence challenge to
    the prior murder, in connection with which Boyer pointed to
    problems with the eyewitness identification, the panel held
    that fairminded jurists could disagree on the correctness of
    the state court’s decision that the evidence that Boyer
    committed the murder was sufficient.
    Regarding Boyer’s claim that trial counsel deficiently
    failed to investigate the possibility that Boyer suffered from
    organic brain damage at the guilt phase of the trial, the panel
    held that it was not unreasonable for the state court to
    conclude that Boyer’s counsel conducted a thorough
    investigation into his mental state and that such investigation
    satisfied the performance prong of Strickland v. Washington.
    The panel also held that Boyer failed to demonstrate the
    requisite prejudice. The panel held that the district court did

    BOYER V. CHAPPELL                         3
    not err when it denied for largely the same reasons Boyer’s
    claim that trial counsel deficiently failed to investigate the
    possibility that he suffered from organic brain damage at the
    penalty phase.
    The panel rejected as foreclosed by precedent Boyer’s
    contentions that the California death penalty is
    unconstitutional by virtue of (1) the statutory scheme’s failure
    to narrow adequately the class of eligible defendants and
    (2) prosecutorial discretion.
    The panel declined to certify two claims relating to the
    admission of testimony given pursuant to an agreement that
    the testimony would be consistent with prior statements to the
    police.
    Certifying three previously-uncertified claims, the panel
    held that Boyer is not entitled to relief on his contentions that
    the trial court erred when it sua sponte failed to instruct the
    jury that unconsciousness is a complete defense and failed to
    define unconsciousness, and that trial counsel provided
    ineffective assistance for failure to request such instructions.

    Lise S. Jacobson, Deputy Attorney General for the State of
    California, San Diego, California, argued the cause for the
    appellee the State of California. Kamala D. Harris, Attorney
    General of California, filed the briefs for the appellee. With
    her on the briefs were Julie L. Garland, Senior Assistant
    Attorney General, and Robin Urbanski, Deputy Attorney
    General, San Diego, California.
    Joel Levine, Costa Mesa, California, and R. Clayton Seaman,
    Prescott, Arizona, argued the cause on behalf of the
    petitioner-appellant Richard Delmer Boyer and filed briefs.
    OPINION
    O’SCANNLAIN, Circuit Judge:
    We must decide whether the California Supreme Court
    violated the United States Constitution in affirming a habeas
    petitioner’s two first degree murder convictions and his death
    sentence.
    I
    A California state court jury convicted Richard Delmer
    Boyer of the double murder of an elderly couple, Francis and
    Aileen Harbitz. After a separate penalty proceeding, the jury
    returned a sentence of death.1
    1
    Boyer was tried three times for the Harbitzes’ murders. The first trial
    ended when, after deliberating for 8 days, the jury failed to reach a verdict.
    A second jury convicted Boyer of murdering the Harbitzes, but the

    At the guilt phase of trial, the prosecution showed that the
    Harbitzes had been stabbed to death in their Fullerton,
    California home on December 7, 1982. When their son
    William Harbitz entered the home five days later, he
    discovered his father’s body sitting upright against a bloody
    wall in the hallway and his mother’s body covered in blood
    on the living room floor. Francis had sustained approximately
    24 stab wounds to the neck, chest, and back, and bled to death
    because of knife wounds to the heart and aorta. Aileen had
    suffered 19 stab wounds and likewise bled to death as a result
    of her injuries. The Harbitzes’ residence did not show signs
    of forced entry nor had it been ransacked, and there was
    approximately $400 worth of cash in the home when the
    bodies were discovered.
    After discovering his parents’ bodies, William mentioned
    Boyer’s name to police. William had introduced Boyer to his
    parents, and Boyer had done odd jobs for the Harbitzes and
    borrowed money from them on occasion. William had come
    to know Boyer because they had previously lived in the same
    apartment complex.
    California Supreme Court reversed that conviction, concluding that police
    officers violated Boyer’s constitutional rights during questioning that led
    to a confession. The Court determined, however, that the illegal
    confession had not tainted the physical evidence, and reversed and
    remanded for a new trial. The third trial, held in 1992, is the one at issue
    here.
    6                   BOYER V. CHAPPELL
    When police subsequently searched the residence that
    Boyer maintained with his girlfriend, Cynthia Cornwell,
    officers found a pair of Levi’s jeans stained with blood
    consistent with Boyer’s and blood consistent with that of both
    Francis and Aileen Harbitz. Officers also recovered a buck
    knife, capable of inflicting the Harbitzes’ wounds and stained
    with human blood, as well as the charred remains of a jacket
    burned in a hibachi grill.
    John Kennedy, a key prosecution witness, testified under
    a grant of immunity that he had arrived at Boyer’s residence
    between 4:30 and 5:00 p.m. on the afternoon of December 7,
    and that Boyer asked for a ride to his father’s house to pick
    up some money. Along the way, Kennedy and Boyer stopped
    to buy cocaine from a dealer Kennedy knew, using $25
    Kennedy had borrowed from his brother. They then
    proceeded to the home of Boyer’s father, where Boyer spent
    approximately 15 minutes inside.
    Kennedy and Boyer then drove to an apartment complex
    and attempted to buy marijuana, but failed. Boyer then
    directed Kennedy to another apartment complex to find
    “Bill.” The pair failed to locate Bill, and Boyer speculated
    that Bill had moved back in with his parents. Boyer then
    directed Kennedy to “some dope dealer’s house,” which
    Boyer later revealed to be “Bill’s parents’ house”—that is, the
    Harbitzes’ residence. Bill, of course, was William Harbitz.
    Kennedy testified that Boyer entered the Harbitzes’ home
    acting normally and remained inside for about 45 minutes. He
    returned, again acting normally, with a towel in hand. When
    a police patrol vehicle approached, Boyer began wiping the
    vehicle’s rear window with the towel and shortly thereafter
    BOYER V. CHAPPELL                       7
    admonished Kennedy to “take off calmly, not to attract any
    attention.”
    As they drove away, Kennedy observed Boyer apply the
    towel to his left knee. Boyer told Kennedy that he had to hurt
    someone because they didn’t “have no dope” and indicated
    that he had been stabbed himself. Soon after, Kennedy saw
    Boyer going through two wallets. Boyer threw one of the
    wallets out a window near an off ramp and put the other down
    a gutter. When the pair returned to Boyer’s residence,
    Kennedy observed a stab wound to Boyer’s knee. He also saw
    that Boyer was wearing his buck knife, and, before he left the
    residence, noted that there was blood on the open knife blade.
    During the evening, Boyer told Kennedy not to tell anyone
    what had happened that night.
    Cynthia Cornwell likewise testified for the prosecution
    under a grant of immunity and reported that Boyer and
    Kennedy had left the residence Boyer and Cornwell shared so
    that Boyer could attempt to borrow money from his parents.
    He had previously tried to borrow $30 from Cornwell, which
    she knew to be the price of cocaine, but she had no money to
    give him.
    Cornwell testified that, later that evening, when Boyer
    and Kennedy returned, Boyer’s knee was bleeding and he was
    limping. Boyer told Cornwell that he had been injured in a
    confrontation with a loan shark. That same day, before police
    officers came to their residence, Boyer asked Cornwell
    whether she would wait for him if something happened.
    When Cornwell asked what was wrong, Boyer said
    “something about a murder” and told Cornwell “you are
    going to hate me.” Cornwell admitted to burning Boyer’s
    jacket on a hibachi grill.

    2
    For the defense, Dr. Ernest Klatte testified as an expert
    witness after interviewing Boyer four times for a total of
    eight and three-quarter hours. In addition to those interviews,
    Dr. Klatte reviewed reports prepared by the public defender
    and the Fullerton police, a forensic report prepared by the
    Orange County Sheriff’s crime lab, and Boyer’s medical
    records, which included indications that Boyer had suffered
    two serious traffic incidents years earlier.
    Dr. Klatte related Boyer’s version of the events.
    According to him, Boyer stated that he had been injecting
    cocaine and drinking heavily for some time. On the day of the
    murders, he drank beer in the morning and half a pint of
    whiskey in the afternoon, smoked a PCP cigarette, and shared
    a quarter gram of cocaine with Kennedy. He went with
    Kennedy to his parents’ house in an attempt to obtain money
    from his mother, but failed because his father was home. He
    then attempted to find William Harbitz, but, again, failed. The
    two then went to Francis and Aileen Harbitz’s home to find
    out how to contact William. During the trip, he began to have
    a headache and feel the effects of the PCP. Once they arrived
    at the Harbitzes’ residence, Aileen Harbitz invited him into
    her home, and subsequently suggested he go to the back
    bedroom to talk to Francis. As he was leaving Francis’s room,
    Boyer noticed a billfold and then felt very strange. Boyer felt
    that he was part of the horror movie Halloween II and that
    events in the house were changing speeds and items were
    becoming distorted.
    Boyer’s story changed significantly over the course of his
    interviews with Dr. Klatte. In his early interviews, conducted
    in 1982 and 1983, Boyer stated he had no recollection of the
    BOYER V. CHAPPELL                          9
    knife or the stabbing, and indeed had no recollection at all
    until he was outside in Kennedy’s car. In a 1990 interview,
    however, Boyer said that he was “tripping” and hallucinated
    a man coming at him with a knife. Dr. Klatte testified that
    Boyer recalled having two wallets when he left the Harbitzes’
    residence, and that he admitted to discarding them.
    Dr. Klatte opined, assuming Boyer told the truth about the
    drugs he ingested, that Boyer might have been impulsive and
    explosive on the night of the murders, and that he might have
    hallucinated. He also acknowledged Boyer had an antisocial
    personality and might have lied about the events in question.
    Dr. Klatte testified there was a significant possibility Boyer
    was malingering, and he was especially suspicious of the
    hallucination claim because Boyer had not mentioned it to
    him until 1990.
    Lawrence Plon, a pharmacist, also testified for the defense
    that cocaine and PCP can produce excitement or catatonic
    withdrawal, aggression, paranoia, hallucinations, and
    delusions.
    In due course, the jury returned guilty verdicts on the two
    murder charges.
    B
    At the penalty phase of the trial, the parties stipulated that
    Boyer pled guilty to committing a misdemeanor assault in
    September 1980. The prosecution also presented evidence
    that Boyer participated in the armed robbery of a Payless
    Shoe Source store cashier in 1982, during which Boyer had
    personally pulled a handgun on a store clerk, forcing her to
    open the cash register and store safe.
    10                  BOYER V. CHAPPELL
    In addition, the prosecution sought to prove that Boyer
    murdered 75 year old Houston Compton in August 1980.
    William Harbitz testified that in August, 1980, Boyer came
    to his apartment door intoxicated and covered in blood and
    subsequently explained he had been in a knife fight. The
    prosecution’s case relied heavily on the testimony of Linda
    Weissinger, who worked at a McDonald’s restaurant in
    Whittier, California. She recalled a man driving a car that
    matched Compton’s early 1960’s Ford Fairlane—which was
    later found abandoned with a McDonald’s restaurant bag and
    receipt inside—going through the McDonald’s drive-through
    during the closing rush. Weissinger recalled the man had
    blood on his shirt and leaned toward the passenger side of the
    window as if he did not want to be seen. Despite only briefly
    seeing the man, Weissinger positively identified Boyer in a
    six photograph array in 1983 and testified that she was “sure”
    the man she identified in 1983 and the man she had seen at
    the McDonald’s were the same.
    Weissinger’s eyewitness identification was in many ways
    problematic. In two live lineups, conducted in 1980 and 1981
    Weissinger identified men other than Boyer as the man she
    saw in the McDonald’s drive-through. In a later photographic
    array, she chose someone other than Boyer before identifying
    Boyer in yet another photographic array. Nonetheless, at trial,
    she “explained at length why she felt sure of her choice”
    when she identified Boyer in the latter photographic array
    after the prior, incorrect identifications.
    Boyer presented evidence concerning the unreliability of
    eyewitness reports, evidence of his difficult upbringing, and
    significant testimony concerning his character in mitigation.
    In any event, the jury returned a penalty of death.

    The California Supreme Court unanimously affirmed the
    convictions and sentence in Boyer’s direct appeal with a
    reasoned opinion, People v. Boyer, 
    38 Cal. 4th 412
    (2006),
    and the United States Supreme Court denied Boyer’s petition
    for certiorari. Boyer v. California, 
    549 U.S. 1021
    (2006). On
    state habeas review, the California Supreme Court twice
    denied Boyer’s petition for a writ of habeas corpus on the
    merits. Boyer subsequently filed this federal habeas petition,
    which the district court denied in full. Boyer timely
    appealed.2
    II
    Boyer’s claims are governed by the Antiterrorism and
    Effective Death Penalty Act of 1996 (the “AEDPA”).3 Our
    statutory authority to grant habeas corpus relief to state
    prisoners arises exclusively from 28 U.S.C. § 2254(d), which
    states in relevant part that:
    An application for a writ of habeas corpus on
    behalf of a person in custody pursuant to the
    judgment of a State court shall not be granted
    2
    The district court had jurisdiction under 28 U.S.C. § 2254.We have
    jurisdiction over the appeal from the denial of Boyer’s habeas petition
    under 28 U.S.C. § 2253(a), and review the district court’s denial of a
    petition for habeas corpus de novo. Walker v. Martel, 
    709 F.3d 925
    , 939
    (9th Cir. 2013).
    3
    AEDPA sets forth the relevant standard of review because Boyer filed
    his habeas petition in the district court in June 2010, well after AEDPA’s
    effective date. Lindh v. Murphy, 
    521 U.S. 320
    , 336–37 (1997); Hedlund
    v. Ryan, 
    750 F.3d 793
    , 798–99 (9th Cir. 2014).

    with respect to any claim that was adjudicated
    on the merits in State court proceedings unless
    the adjudication of the claim—
    (1) resulted in a decision that was contrary to,
    or involved an unreasonable application of,
    clearly established Federal law, as determined
    by the Supreme Court of the United States; or
    (2) resulted in a decision that was based on an
    unreasonable determination of the facts in
    light of the evidence presented in the State
    court proceeding.
    “[C]learly established Federal law, as determined by the
    Supreme Court of the United States . . . refers to the holdings,
    as opposed to the dicta, of [the Supreme Court’s] decisions as
    of the time of the relevant state-court decision.” Williams v.
    Taylor, 
    529 U.S. 362
    , 412 (2000) (internal quotation marks
    omitted). “‘[A]n unreasonable application of federal law is
    different from an incorrect application of federal law,’”
    because “[a] state court must be granted a deference and
    latitude.” Harrington v. Richter, 
    562 U.S. 86
    , 101 (2011)
    (quoting 
    Williams, 529 U.S. at 410
    ). Under such deferential
    standard, “[a] state court’s determination that a claim lacks
    merit precludes federal habeas relief so long as ‘fairminded
    jurists could disagree’ on the correctness of the state court’s
    decision.” 
    Id. (quoting Yarborough
    v. Alvarado, 
    541 U.S. 652
    , 664 (2004)).
    As the Supreme Court has repeatedly been obliged to
    remind us, this standard is “difficult to meet . . . because it
    was meant to be.” 
    Id. at 102
    (explaining that “habeas corpus
    is a guard against extreme malfunctions in the state criminal
    BOYER V. CHAPPELL                               13
    justice systems” rather than “a substitute for ordinary error
    correction” (citation omitted) (internal quotation marks
    omitted)). Thus, “[a]s a condition for obtaining habeas corpus
    from a federal court, a state prisoner must show that the state
    court’s ruling on the claim being presented in federal court
    was so lacking in justification that there was an error well
    understood and comprehended in existing law beyond any
    possibility for fairminded disagreement.” 
    Id. at 103.
    We apply this demanding standard to Boyer’s petition,
    beginning with the four claims certified4 by the district court
    followed by his five uncertified claims.
    III
    A
    Boyer first contends the district court erred when it
    concluded that no clearly established federal law required the
    trial court to conduct a full evidentiary hearing before
    admitting evidence of the Compton murder at the penalty
    phase. Boyer urges that, at least in this case, the trial court
    was required to hear live testimony to determine whether the
    evidence tying Boyer to the Compton murder was sufficiently
    reliable to be admitted. He also suggests, even if such hearing
    were not necessary, that the evidence should nonetheless have
    been excluded. His argument principally relates to the
    testimony of Linda Weissinger.
    4
    “Before an appeal may be entertained, a prisoner who was denied
    habeas relief in the district court must first seek and obtain a [certificate
    of appealability].” Miller–El v. Cockrell, 
    537 U.S. 322
    , 335–36 (2003);
    see 28 U.S.C. § 2253(c).
    14                     BOYER V. CHAPPELL
    1
    On direct review, the California Supreme Court held that
    no error had occurred in the trial court’s failure to conduct a
    live evidentiary hearing. Although not specifically stating that
    no hearing was required, it “independently conclude[d]” that
    “Weissinger’s identification testimony at trial was not
    excludable . . . and [] the evidence that defendant murdered
    Compton was legally sufficient for consideration by the
    penalty jury.” 
    Boyer, 38 Cal. 4th at 477
    . On federal habeas
    review, the district court noted that, while the trial court had
    not heard live evidence regarding Weissinger’s testimony, it
    had conducted three hearings on the matter. The district court
    also agreed that Boyer had identified no clearly established
    federal law entitling him to an evidentiary hearing.
    Boyer relies principally on People v. Phillips, 
    41 Cal. 3d 29
    (1985). There, the California Supreme Court explained
    that, before allowing the introduction of evidence concerning
    prior uncharged offenses, “it may be advisable for the trial
    court to conduct a preliminary inquiry before the penalty
    phase to determine whether there is substantial evidence to
    prove each element of the other criminal activity” at issue. 
    Id. at 72
    n.25. Phillips, of course, is not a Supreme Court case
    and so does not represent “clearly established Federal law,”
    which embodies “the governing legal principle or principles
    set forth by the Supreme Court at the time the state court
    render[ed] its decision.” Lockyer v. Andrade, 
    538 U.S. 63
    ,
    71–72 (2003).5
    5
    At oral argument, counsel for Boyer contended that our opinion in
    Hurles v. Ryan, 
    752 F.3d 768
    (9th Cir. 2014), stands for the proposition
    that, when there has been a prima facie showing of a constitutional
    violation and a request for an evidentiary hearing has been made but no
    BOYER V. CHAPPELL                               15
    Boyer, however, points to three Supreme Court cases he
    contends create clearly established federal law requiring the
    trial court to conduct a Phillips hearing. The first, Neil v.
    Biggers, 
    409 U.S. 188
    (1972), is a pre-AEDPA case involving
    whether a rape victim’s identification of her attacker
    comported with due process. Rather than identifying the
    accused in a lineup, police showed the victim the accused
    alone because no suitable lineup could be constructed from
    the occupants of the city jail or the city juvenile home. 
    Id. at 195.
    The Biggers Court concluded such identification did not
    violate due process, and held the “central question” was
    “whether under the totality of the circumstances the
    identification was reliable even though the confrontation
    procedure was suggestive.” 
    Id. at 199
    (internal quotation
    marks omitted). It did not address what type of evidentiary
    hearing the trial court needed to conduct in determining
    whether the eyewitness identification could be put before the
    jury.
    Boyer also relies on Manson v. Brathwaite, 
    432 U.S. 98
    (1977). That case largely followed Biggers, holding
    “reliability is the linchpin in determining the admissibility of
    identification testimony” and concluding “[t]he factors to be
    considered [we]re set out in Biggers.” 
    Id. at 114.
    Like
    such hearing has occurred, state court determinations are, in general, owed
    less deference on habeas review. Such contention is incorrect.
    In Hurles, we evaluated the Supreme Court’s clearly established
    caselaw regarding judicial bias and determined that, based on the facts of
    that case, the state court’s denial of Hurles’s judicial bias claim “rest[ed]
    on an unreasonable determination of the facts.” 
    Id. at 790.
    Our holding in
    that case does not affect the level of deference generally owed to state
    court determinations under § 2254(d). Boyer’s claims are governed by the
    stringent AEDPA standard set forth by many Supreme Court cases.
    16                  BOYER V. CHAPPELL
    Biggers, Manson contains no discussion regarding when a
    trial court must conduct a live evidentiary hearing before
    allowing eyewitness testimony. In sum, if Biggers and
    Brathwaite relate to Boyer’s claim at all, they are of no help
    to him.
    Boyer next points to Watkins v. Sowders, 
    449 U.S. 341
    (1981). There, the Court addressed whether a “trial court is
    constitutionally compelled to conduct a hearing outside the
    presence of the jury whenever a defendant contends that a
    witness’ identification of him was arrived at improperly.” 
    Id. at 342.
    The Watkins Court concluded the Constitution
    required no such hearing, explaining “[a] judicial
    determination outside the presence of the jury of the
    admissibility of identification evidence may often be
    advisable . . . [b]ut it does not follow that the Constitution
    requires a per se rule compelling such a procedure in every
    case.” 
    Id. at 349.
    It noted “the proper evaluation of evidence
    under the instructions of the trial judge is the very task our
    system must assume juries can perform,” 
    id. at 347,
    but also
    suggested that “[i]n some circumstances” a hearing outside
    the presence of a jury to determine the admissibility of
    evidence “may be constitutionally necessary,” 
    id. at 349.
    Watkins, though, never elaborates. 
    Id. Moreover, the
    Supreme
    Court did not squarely hold that an evidentiary hearing is ever
    required in any particular circumstances—indeed, it did not
    provide any guidance as to when such circumstances might
    arise. A state court could reasonably conclude that Watkins
    does not constitute clearly established federal law that could
    entitle Boyer to relief.
    More recently, in Perry v. New Hampshire, 
    132 S. Ct. 716
    , 723 (2012), the Court examined when a trial court is
    obliged to evaluate allegedly unreliable “eyewitness
    BOYER V. CHAPPELL                       17
    identification made under suggestive circumstances not
    arranged by the police” before such identification may be
    presented to a jury. The Perry Court held that “[o]nly when
    evidence is so extremely unfair that its admission violates
    fundamental conceptions of justice . . . have we imposed a
    constraint tied to the Due Process Clause.” 
    Id. (citation omitted)
    (internal quotation marks omitted). It explained “the
    Due Process Clause does not require a preliminary judicial
    inquiry into the reliability of an eyewitness identification
    when the identification was not procured under unnecessarily
    suggestive circumstances arranged by law enforcement.” 
    Id. at 730.
    While Boyer contends Weissinger’s testimony was
    unreliable in many respects, he does not contend such
    unreliability stems from unnecessarily suggestive
    circumstances arranged by law enforcement. Thus, Perry
    likewise does not entitle Boyer to relief.
    We therefore conclude that the state court did not
    unreasonably apply clearly established Supreme Court
    precedent when it determined that federal law did not require
    a live evidentiary hearing to assess the reliability of Lisa
    Weissinger’s testimony.
    2
    Boyer further presses the related argument that evidence
    of the Compton homicide should have been excluded as
    insufficient and unreliable. His contention takes the form of
    a sufficiency of the evidence claim under Jackson v. Virginia,
    
    443 U.S. 307
    , 318 (1979) (holding that “the critical inquiry
    on review of the sufficiency of the evidence . . . [is] whether
    the record evidence could reasonably support a finding of
    guilt beyond a reasonable doubt”).
    18                   BOYER V. CHAPPELL
    Under Jackson, “evidence is sufficient to support a
    conviction so long as ‘after viewing the evidence in the light
    most favorable to the prosecution, any rational trier of fact
    could have found the essential elements of the crime beyond
    a reasonable doubt.’” Cavazos v. Smith, 
    132 S. Ct. 2
    , 6 (2011)
    (per curiam) (quoting 
    Jackson, 443 U.S. at 319
    ). On habeas
    review, “the deference to state court decisions required by
    § 2254(d)” combines with “the state court’s already
    deferential review” of sufficiency of the evidence claims. Id.;
    see Juan H. v. Allen, 
    408 F.3d 1262
    , 1274 (9th Cir. 2005)
    (recognizing AEDPA and Jackson combine to create double
    deference).
    To buttress his argument, Boyer points to several
    problems with Weissinger’s identification. For example, in
    the two live lineups, Weissinger identified men other than
    Boyer. She also identified men other than Boyer in
    photographic lineups before finally choosing Boyer in a
    photographic array in 1983.
    In deciding no error had occurred, the California Supreme
    Court explained that “[i]dentification of the defendant by a
    single eyewitness may be sufficient to prove the defendant’s
    identity as the perpetrator of a crime” and concluded that “the
    evidence that [Boyer] murdered Compton was sufficient.”
    
    Boyer, 38 Cal. 4th at 480
    . It relied upon the fact that
    “Weissinger readily testified that, after careful consideration,
    she made a positive identification of defendant from a photo
    array as the McDonald’s customer she saw on the night of the
    Compton murder,” and she “explained at length why she felt
    sure of her choice.” 
    Id. The Court
    further explained Boyer’s
    counsel had “a full opportunity to cross-examine Weissinger
    . . . about all aspects of the identification process” and that
    “William Harbitz provided some independent evidence of
    BOYER V. CHAPPELL                        19
    defendant’s identity as Compton’s killer” by describing the
    August 1980 incident when Boyer informed Harbitz that he
    had been in a knife fight while wearing a bloody shirt. 
    Id. at 481.
    In light of these facts and the applicable standard of
    review, we conclude that, at the very least, “fairminded jurists
    could disagree” on the correctness of the state court’s
    decision. 
    Richter, 562 U.S. at 101
    (internal quotation marks
    omitted). And, as the Supreme Court has repeatedly
    emphasized, that is all that is required.
    B
    Boyer next contends the district court erred when it
    denied his claim that his trial counsel deficiently failed to
    investigate the possibility that Boyer suffered from organic
    brain damage at the guilt phase of the trial. Based on testing
    performed in 2001 by Dr. Natasha Khazanov during post-
    conviction proceedings, Boyer contends he suffered from
    severe organic brain damage and, moreover, that counsel’s
    failure to investigate such possibility amounted to ineffective
    assistance of counsel under Strickland v. Washington, 
    466 U.S. 668
    (1984). Boyer contends evidence of organic brain
    damage would have bolstered defenses of unconsciousness,
    insanity, and unconsciousness due to intoxication.
    In order to succeed on a Strickland claim, a claimant must
    “show that counsel’s performance was deficient” and that
    “the deficient performance prejudiced the defense.” 
    Id. at 687.
    To demonstrate deficient performance Boyer “must
    show that counsel’s representation fell below an objective
    standard of reasonableness,” and, in making that
    determination, courts must “indulge a strong presumption that
    20                  BOYER V. CHAPPELL
    counsel’s conduct falls within the wide range of reasonable
    professional assistance.” 
    Id. at 688–89.
    In order to show
    prejudice, Boyer must show “there is a reasonable probability
    that, but for counsel’s unprofessional errors, the result of the
    proceeding would have been different.” 
    Id. at 694.
    We can
    only grant relief based on counsel’s alleged ineffectiveness if
    both criteria have been met.
    Because Boyer brings his Strickland claim on federal
    habeas, he must surmount an even higher bar. On habeas
    review, we examine whether the state court reasonably
    applied Strickland. “The standards created by Strickland and
    § 2254(d) are both highly deferential,” giving rise to
    “doubl[e]” deference. 
    Richter, 562 U.S. at 105
    (internal
    quotation marks omitted). “[T]he question is not whether
    counsel’s actions were reasonable. The question is whether
    there is any reasonable argument that counsel satisfied
    Strickland’s deferential standard.” 
    Id. (emphasis added).
    1
    Boyer’s claim turns primarily on his counsel’s alleged
    failure to investigate further the diagnosis by Dr. Kenneth
    Nudleman. One of the several experts to evaluate Boyer’s
    mental state, Dr. Nudleman performed an MRI on Boyer’s
    brain, the results of which were normal. However, an
    electroencephalogram showed abnormalities, and Dr.
    Nudleman recommended neuropsychometric testing and a
    PET scan. No such testing appears to have been performed,
    BOYER V. CHAPPELL                               21
    and Boyer alleges this failure to secure such testing amounted
    to ineffective assistance of counsel.6
    Boyer’s argument fails, however, to credit the extensive
    investigation his counsel performed into his mental
    state—indeed, Boyer was evaluated by numerous mental
    health experts in preparation for his multiple trials. In
    addition to Dr. Klatte and Dr. Plon, Boyer was evaluated by
    Dr. Ronald Siegel, a psychopharmacologist, who testified at
    Boyer’s second trial that Boyer could have had a flashback,
    but provided no indication that he suffered from organic brain
    damage. Similarly, Dr. Jonathan Salk, a psychiatrist,
    evaluated Boyer for signs of post traumatic stress disorder,
    but made no mention of the possibility of organic brain
    damage.
    Two court-appointed physicians also evaluated Boyer.
    One, Dr. William Loomis, a psychiatrist and neurologist,
    concluded Boyer was sane at the time of the crime and at the
    time of examination. Dr. Loomis did not credit the possibility
    of organic brain damage. Dr. Edward Kaufman, a psychiatrist
    and assistant professor of psychology, concluded that Boyer
    6
    Boyer places great weight on a declaration by his trial counsel stating
    that he did not make a tactical decision when he failed pursue Dr.
    Nudleman’s recommendations. In short, Boyer argues that the record
    before the state courts will only support the conclusion that counsel did
    not make such a tactical decision. The Supreme Court, however, has
    repeatedly cautioned that “[a]fter an adverse verdict at trial even the most
    experienced counsel may find it difficult to resist asking whether a
    different strategy might have been better, and, in the course of that
    reflection, to magnify their own responsibility for an unfavorable
    outcome.” 
    Richter, 562 U.S. at 109
    . “Strickland . . . calls for an inquiry
    into the objective reasonableness of counsel’s performance, not counsel’s
    subjective state of mind.” 
    Id. at 110.
    The declaration, therefore, cannot
    bear the weight Boyer ascribes to it.
    22                   BOYER V. CHAPPELL
    suffered from an antisocial personality and from chronic
    substance abuse. Dr. Kaufman thoroughly considered Boyer’s
    medical history and found that it was unlikely Boyer suffered
    from a hallucination during the Harbitzes’ murders. While Dr.
    Kaufman was aware Boyer had been in a car accident in 1976
    and had subsequently undergone a neurological examination,
    Dr. Kaufman did not suggest a likelihood of organic brain
    damage. Rather, Dr. Kaufman stated that neurological illness
    was unlikely and could best be ruled out by diagnostic
    testing.
    We have previously denied claims relating to alleged
    failures to investigate organic brain damage in similar
    circumstances. For example, in Earp v. Cullen, we held that
    the petitioner had failed to demonstrate that his trial counsel’s
    conduct fell below Strickland’s standard on AEDPA review
    where medical experts “concluded that [the petitioner] had
    deficits in processing speed and working memory that were
    consistent with organic brain damage.” 
    623 F.3d 1065
    , 1076
    (9th Cir. 2010). We concluded counsel was not ineffective in
    large part because he had pursued evidence related to Earp’s
    mental state and abilities at the time of the trial, and because
    a psychologist who examined Earp concluded instead that
    Earp was a sociopath. 
    Id. Moreover, we
    held that the fact that
    Earp could produce an expert eleven years after the trial “who
    is willing to opine that he had organic brain damage at the
    time of his trial does not impact the ultimate determination of
    whether Earp’s trial counsel insufficiently investigated that
    possibility.” 
    Id. We reached
    a similar conclusion in West v. Ryan, where
    we held petitioner’s counsel had not fallen below the
    Strickland standard by failing to follow up on a medical
    expert’s conclusion that “cognitive impairment could not be
    BOYER V. CHAPPELL                              23
    ‘ruled out’ absent further testing.” 
    608 F.3d 477
    , 488–89 (9th
    Cir 2010). Based on the totality of the circumstances, that
    remark was “not the kind of powerful mitigating evidence
    sufficient to overcome Strickland’s presumption that counsel
    acted reasonably in declining to investigate further the
    possibility . . . [of] cognitive impairment.” 
    Id. at 489
    (internal
    quotation marks omitted).
    In Leavitt v. Arave, 
    646 F.3d 605
    , 609–10 (9th Cir.
    2011), we again found that trial counsel satisfied Strickland
    under similar circumstances. There, the petitioner argued trial
    counsel could not have made a reasonable strategic decision
    not to investigate further a CT scan that revealed cortical
    atrophy and suggested a possibility of disease. 
    Id. While the
    petitioner’s doctor “may have found some evidence
    suggesting a cognitive impairment,” he “ultimately concluded
    that the results . . . were more consistent with a diagnosis of
    a personality disorder,” and we held that no additional testing
    was required to satisfy Strickland. 
    Id. at 609.
    Confronted with multiple medical evaluations, none of
    which identified organic brain damage, Boyer’s trial counsel
    could justifiably have concluded that further investigation
    was unnecessary. As in Earp, West, and Leavitt, we are
    satisfied that it was not unreasonable for the California
    Supreme Court to conclude that Boyer’s counsel conducted
    a thorough investigation into his mental state and that such
    investigation satisfied the performance prong of Strickland,
    especially in light of the double deference owed that
    conclusion on federal habeas review.7
    7
    Boyer also relies on Wiggins v. Smith, 
    539 U.S. 510
    (2003), a case in
    which the Supreme Court held that trial counsel’s cursory investigation
    into mitigating circumstances related to the petitioner’s life history fell
    24                      BOYER V. CHAPPELL
    2
    Moreover, Boyer has failed to demonstrate the prejudice
    required to mount successfully a Strickland claim. In order to
    show prejudice, “[t]he defendant must show that there is a
    reasonable probability that, but for counsel’s unprofessional
    errors, the result of the proceeding would have been
    different.” Cullen v. Pinholster, 
    131 S. Ct. 1388
    , 1403 (2011)
    (quoting 
    Strickland, 466 U.S. at 694
    ). “A reasonable
    probability is a probability sufficient to undermine confidence
    in the outcome.” 
    Id. (internal quotation
    marks omitted). A
    substantial likelihood of a different result, as opposed to a
    mere conceivable possibility, is required. 
    Id. In light
    of the compelling evidence adduced against him
    at trial, Boyer cannot show that there is a reasonable
    probability of a different result had his counsel pursued
    additional evidence of organic brain damage. The evidence
    at trial discredits the idea that Boyer suffered from a
    hallucination or was otherwise unconscious or insane when
    he murdered the Harbitzes. For example, as the California
    Supreme Court noted, Boyer appeared “mentally normal at all
    times during the evening” of the murder. 
    Boyer, 38 Cal. 4th at 470
    –71. He tried to deflect suspicion when he saw a police
    patrol car and told Kennedy to drive away without attracting
    attention. 
    Id. at 470.
    He disposed of the Harbitzes’ wallets,
    did not tell either Kennedy or Cornwell about the alleged
    below Strickland’s standard. That case is easily distinguishable on the
    facts. There, counsel performed no investigation into the petitioner’s life
    history beyond reviewing a one page summary contained in a presentence
    investigation report and unrelated department of social services records.
    
    Id. at 523–24.
    Here, as discussed, Boyer’s counsel conducted a detailed
    investigation into his mental state.
    BOYER V. CHAPPELL                       25
    hallucination, and lied to both Kennedy and Cornwell to
    explain his knife wounds. 
    Id. at 421–22.
    In addition, Dr. Klatte and Dr. Kaufman, experts obtained
    by the defense and the trial court respectively, expressed
    skepticism regarding Boyer’s story. 
    Id. at 459–60,
    470. Dr.
    Klatte’s testimony, in particular, seriously undermined
    Boyer’s claim he was unconscious or insane at the time of the
    murders when he revealed that Boyer had not informed him
    of the hallucination until years after the murders took place.
    Thus, even if Boyer’s counsel had been ineffective for
    failing to investigate further the possibility of organic brain
    damage, Boyer has failed to show there was a “reasonable
    probability that, but for counsel’s unprofessional errors, the
    result of the proceeding would have been different.”
    
    Strickland, 466 U.S. at 694
    .
    C
    Boyer next contends the district court erred when it
    denied his claim that his trial counsel deficiently failed to
    investigate the possibility Boyer suffered from organic brain
    damage at the penalty phase of the trial. Boyer marshals
    largely the same legal arguments and facts as he employed to
    support his contention that counsel provided ineffective
    assistance of counsel at the guilt phase of the trial.
    We therefore conclude that the district court did not err
    when it denied Boyer’s claim for largely the same reasons. As
    we concluded in Earp, West, and Leavitt, and for the reasons
    we have already explained, we conclude that trial counsel
    could justifiably have decided that further investigation into
    the possibility of organic brain damage was unnecessary in
    26                  BOYER V. CHAPPELL
    light of the many experts who investigated Boyer’s mental
    state but made no mention of such condition. Moreover, the
    reasons we have already identified demonstrate Boyer
    suffered no prejudice, even supposing that his counsel’s
    investigation was deficient. Evidence suggested that Boyer
    was in search of money when he entered the Harbitzes’ home,
    that he took the Harbitzes’ wallets and later hid them, that he
    attempted to avoid arousing suspicion as he left the
    Harbitzes’ home, and that he attempted to mislead both
    Kennedy and Cornwell about the cause of injuries he
    sustained while inside the home. Moreover, Boyer’s own
    experts doubted his proffered explanation of events, in part
    because that explanation changed significantly over time. We
    therefore conclude that Boyer has failed to demonstrate that
    counsel’s alleged deficient performance in failing to
    investigate adequately the possibility of organic brain damage
    prejudiced him at the penalty phase.
    D
    Finally, Boyer contends the district court erred when it
    concluded California’s death penalty procedures do not
    violate the Fifth, Eighth, and Fourteenth Amendments to the
    United States Constitution. Boyer argues both that the State’s
    statutory scheme fails to narrow adequately the class of
    defendants eligible for the death penalty, and that
    prosecutorial discretion to seek the death penalty renders such
    penalty unconstitutional.
    1
    We have, on multiple occasions, already rejected the
    claim that California’s death penalty scheme fails to narrow
    sufficiently the class of defendants eligible for such
    BOYER V. CHAPPELL                        27
    punishment. In Mayfield v. Woodford, 
    270 F.3d 915
    , 924 (9th
    Cir. 2001) (en banc) we, sitting en banc, held that “[a]
    reasonable jurist could not debate . . . that the 1978 California
    statute, which narrowed the class of death-eligible defendants
    at both the guilt and penalty phases, was constitutional.”
    Likewise, in Karis v. Calderon, 
    283 F.3d 1117
    , 1141 n.11
    (9th Cir. 2002), we expressly “reject[ed] Karis’ argument that
    the [California statutory] scheme does not adequately narrow
    the class of persons eligible for the death penalty,” explaining
    that “[t]he California statute satisfies the narrowing
    requirement” set forth by the Supreme Court.
    We therefore conclude that precedent forecloses Boyer’s
    claim that California’s death penalty scheme is
    unconstitutional.
    2
    Further, Boyer claims that prosecutorial discretion to seek
    the death penalty renders it unconstitutional. This argument
    has likewise been repeatedly rejected by the Supreme Court
    and our Court. See Gregg v. Georgia, 
    428 U.S. 153
    , 199
    (1976) (rejecting claim that Georgia’s death penalty scheme
    was unconstitutional because “the state prosecutor has
    unfettered authority to select those persons whom he wishes
    to prosecute for a capital offense and to plea bargain with
    them”); Proffitt v. Florida, 
    428 U.S. 242
    , 254 (1976) (holding
    argument that “the prosecutor’s decision whether to charge a
    capital offense in the first place” rendered Florida’s death
    penalty unconstitutional represented “a fundamental
    misinterpretation” of Supreme Court precedent and rejecting
    such argument); United States v. Mitchell, 
    502 F.3d 931
    , 982
    (9th Cir. 2007) (explaining claim that prosecutorial discretion
    28                  BOYER V. CHAPPELL
    rendered death penalty unconstitutional was foreclosed). We
    again reject it.
    IV
    Boyer renews his request for a certificate of appealability
    as to the five claims for which the district court denied such
    certificate. Under 28 U.S.C. § 2253(c)(2), “[a] certificate of
    appealability may issue . . . only if the applicant has made a
    substantial showing of the denial of a constitutional right.”
    This standard is satisfied when “‘reasonable jurists could
    debate whether (or, for that matter, agree that) the petition
    should have been resolved in a different manner or that the
    issues presented were adequate to deserve encouragement to
    proceed further.’” 
    Miller–El, 537 U.S. at 336
    (quoting Slack
    v. McDaniel, 
    529 U.S. 473
    , 484 (2000) (citation omitted)
    (internal quotation marks omitted)); see also Shoemaker v.
    Taylor, 
    730 F.3d 778
    , 790 (9th Cir. 2013) (“A certificate of
    appealability should issue if ‘reasonable jurists could debate
    whether’ (1) the district court’s assessment of the claim was
    debatable or wrong; or (2) the issue presented is ‘adequate to
    deserve encouragement to proceed further.’” (quoting 
    Slack, 529 U.S. at 484
    )). In determining whether the substantial
    showing requirement is satisfied, we must not perform a full
    consideration of the merits. 
    Miller–El, 537 U.S. at 336
    (“This
    threshold inquiry does not require full consideration of the
    factual or legal bases adduced in support of the claims. In
    fact, the statute forbids it.”).
    A
    In Boyer’s first uncertified claim, he contends that the
    trial court erred in failing to exclude John Kennedy’s
    testimony because such testimony was given pursuant to an
    BOYER V. CHAPPELL                        29
    agreement which stated that Kennedy’s testimony would be
    consistent with certain prior statements made to police.
    Because Boyer has not identified any clearly established
    Supreme Court precedent suggesting that such a clause
    violates due process or any other constitutional provision, we
    decline to grant a certificate of appealability on this claim.
    See also Cook v. Schriro, 
    538 F.3d 1000
    , 1017 (9th Cir. 2008)
    (“[T]here is no Supreme Court case law establishing that
    consistency clauses violate due process or any other
    constitutional provision.”). We also deny certification of
    Boyer’s second claim, in which he contends that his trial
    counsel provided ineffective assistance of counsel by failing
    to object to Kennedy’s testimony based on the same
    inadmissability concerns. Because any such objection would
    have been fruitless, Boyer’s counsel could not have rendered
    ineffective assistance of counsel by failing to make it.
    B
    In his third, fourth, and fifth uncertified claims, Boyer
    contends that the trial court erred when it sua sponte failed to
    instruct the jury that unconsciousness is a complete defense
    and failed to define unconsciousness. He also contends that
    his trial counsel provided ineffective assistance of counsel for
    failure to request such instructions. We evaluate these claims
    together because they arise from closely related jury
    instructions, and grant a certificate of appealability on each of
    them.
    1
    On direct appeal, the California Supreme Court declined
    to address “whether the trial court erred by failing, sua
    sponte, to instruct on the complete defense of
    30                   BOYER V. CHAPPELL
    unconsciousness” and “[found] that if error occurred, it was
    harmless by any applicable standard.” 
    Boyer, 38 Cal. 4th at 470
    .
    Boyer cites two Supreme Court cases for the proposition
    that the trial court violated clearly established federal law
    when it failed to instruct the jury that unconsciousness is a
    complete defense. The first, Chambers v. Mississippi,
    
    410 U.S. 284
    , 294 (1973), merely held that “[t]he right of an
    accused in a criminal trial to due process is, in essence, the
    right to a fair opportunity to defend against the State’s
    accusations.” But the Court went on to apply that principle in
    the context of the opportunity to call witnesses to testify
    rather than a trial court’s obligations when instructing a jury.
    See 
    id. at 295–303.
    The second case cited by Boyer is equally
    unhelpful. In Rose v. Clark, 
    478 U.S. 570
    , 577–79 (1986), the
    Court held only that an erroneous jury instruction regarding
    malice was subject to harmless error review. In short, Boyer
    has failed to present, nor have we identified, any Supreme
    Court precedent stating clearly established federal law that
    entitles Boyer to the jury instruction at issue. Boyer’s reliance
    on these cases is therefore misplaced.
    Moreover, even if clearly established Supreme Court
    precedent required such instruction, Boyer would still not be
    entitled to relief. The question before us is “whether the ailing
    instruction by itself so infected the entire trial that the
    resulting conviction violates due process.” Estelle v.
    McGuire, 
    502 U.S. 62
    , 72 (1991). “The burden on the habeas
    petitioner is ‘especially heavy’ where, as here, the alleged
    error involves the failure to give an instruction.” Clark v.
    Brown, 
    450 F.3d 898
    , 904 (9th Cir. 2006) (quoting Hendricks
    v. Vasquez, 
    974 F.2d 1099
    , 1106 (9th Cir. 1992)).

    Applying that standard, ample evidence supports the
    California Supreme Court’s determination that any error was
    harmless, including Boyer’s rational appearance throughout
    the day, his goal-directed actions following the murder
    (including instructing Kennedy to avoid police and disposing
    of the Harbitzes’ wallets), the lack of evidence that Boyer
    told Kennedy or Cornwell about his hallucination, and his
    own experts’ skepticism regarding the hallucination claim.

    Boyer next contends that the trial court erred when it
    failed to provide a jury instruction defining unconsciousness,
    and that such failure rendered his trial fundamentally unfair.
    Boyer’s claim suffers from the same deficiencies that
    undermine his contention that the trial court should have
    instructed the jury that unconsiousness is a complete defense.
    Specifically, he has failed to identify any clearly established
    Supreme Court precedent that would entitle him to have the
    state court sua sponte give the additional instruction he
    requests. Moreover, Boyer has failed to bear the especially
    heavy burden placed on him to demonstrate that the lack of
    the requested instruction so infected the trial that his Due
    Process rights were violated.

    Further, we agree with the California Supreme Court, that
    in light of the instructions given by the trial court, “[n]o
    reasonable juror could fail to understand . . . that one can
    perform acts while unconscious.” 
    Boyer, 38 Cal. 4th at 472
    .
    The California Supreme Court noted that the jury instruction
    given on unconsciousness by voluntary intoxication stated
    32                   BOYER V. CHAPPELL
    that an individual who, “‘while unconscious as a result of
    voluntary intoxication, killed another human being without an
    intent to kill and without malice aforethought’ is guilty of
    involuntary manslaughter.” 
    Id. (quoting CALJIC
    No. 8.47).
    Moreover, an individual who becomes voluntarily intoxicated
    “to the point of unconsciousness . . . assumes the risk that
    while unconscious [he] [she] will commit acts dangerous to
    human life or safety.” 
    Id. (quoting CALJIC
    No. 8.47)
    (alterations in original).

    Finally, Boyer contends that his counsel was ineffective
    under Strickland for failing to request jury instructions related
    to unconsciousness. As noted above, the jury was presented
    with numerous instructions explaining the effect of Boyer’s
    alleged unconsciousness and thus a reasonable juror would
    have understood everything necessary to evaluate that theory
    of Boyer’s defense. See United States v. Chambers, 
    918 F.2d 1455
    , 1462 (9th Cir. 1990). Moreover, even if that were not
    so, any error was harmless. As we have already detailed at
    length, should any error have occurred, Boyer has failed to
    demonstrate such error was prejudicial.

    III.B.2;

    For the foregoing reasons, the judgment of the district
    court is
    AFFIRMED.
