    OPINION
    KOZINSKI, Circuit Judge:
    Richard Boyde was convicted in California state court of
    robbery, kidnaping for robbery and murder, and sentenced to
    death. He petitioned the district court for a writ of habeas cor-
    pus, challenging his conviction and sentence. The district
    court denied his petition, and Boyde now appeals.
    Facts1
    1
    For a more detailed discussion of the facts, see the California Supreme
    Court’s opinion in Boyde’s direct appeal, People v. Boyde, 
    758 P.2d 25
    ,
    27-31 (Cal. 1988).
    4494                         BOYDE v. BROWN
    In early January 1981, Boyde robbed David Baker, an
    attendant at a Union 76 gas station in Riverside, California.
    After stealing a small amount of cash and Baker’s watch,
    Boyde forced Baker into Baker’s car and ordered him to drive
    around for several hours. When the car stalled out, Boyde
    asked Baker to give the police a false description of him and
    fled on foot.
    Ten days later, Boyde robbed a 7-Eleven gas station in Riv-
    erside, this time along with his nephew, Carl Franklin Ellison.
    One of the two men went into the station with a gun and took
    some money from a cash register, as well as several hats and
    hatbands.2 They kidnaped Dickie Gibson, the store clerk, and
    drove him to a nearby orange grove. There, Boyde shot Gib-
    son twice in the head, killing him.
    A jury convicted Boyde of robbery and kidnaping for rob-
    bery in connection with the Baker incident, and robbery, kid-
    naping for robbery and first degree murder in the Gibson
    incident.3 After hearing additional evidence, it sentenced him
    to death.
    Boyde exhausted his direct appeals and state habeas pro-
    ceedings. He then petitioned for a writ of habeas corpus in
    federal court, raising a number of claims that his trial and sen-
    tencing violated the Constitution.4 The district court denied
    his petition, and Boyde appeals.
    2
    At trial, Ellison and Boyde disagreed over which of the two had gone
    into the station. Ellison testified that he stayed in the car while Boyde went
    inside, but Boyde claimed he waited outside as Ellison entered the station.
    3
    Ellison was convicted of robbery, kidnaping for robbery and first
    degree murder, and sentenced to a term of 25 years to life.
    4
    Because Boyde filed his habeas petition before April 24, 1996, we do
    not apply the “substantive review standards of the Antiterrorism and
    Effective Death Penalty Act of 1996, Pub. L. No. 104-132, 
    110 Stat. 1214
    (1996) (‘AEDPA’).” Webster v. Woodford, 
    369 F.3d 1062
    , 1066 (9th Cir.
    2004); see also Lindh v. Murphy, 
    521 U.S. 320
    , 327 (1997).
    BOYDE v. BROWN                      4495
    Brady Claim
    One of the key issues at trial was whether Boyde, rather
    than Ellison, shot Gibson. Although there was some physical
    and circumstantial evidence on this score, the big break for
    the prosecution came when Ellison waived his right to trial by
    jury, took the stand in his own defense and testified that
    Boyde had pulled the trigger. According to Boyde, though,
    the prosecution did more than sit idly by and reap the benefits
    of Ellison’s decision to testify. Boyde claims that the prosecu-
    tor and Ellison’s lawyer made a secret deal, pursuant to which
    the prosecutor agreed not to seek the death penalty against
    Ellison, and Ellison agreed to forgo a jury, take the stand and
    finger Boyde as the shooter.
    Had such a deal been made and disclosed, Boyde’s counsel
    could have used it to impeach Ellison’s credibility. But the
    prosecutor said nothing about any promise of leniency to Elli-
    son. Boyde argues that this failure to disclose violated Brady
    v. Maryland, 
    373 U.S. 83
    , 87 (1963). See Giglio v. United
    States, 
    405 U.S. 150
    , 153-55 (1972) (finding a due process
    violation where the prosecution did not disclose that a co-
    conspirator who testified against the defendant at trial had
    been promised that he “would not be prosecuted if he cooper-
    ated with the Government”). The key question is whether a
    secret agreement existed.
    After an evidentiary hearing, the district court found—as
    the California Supreme Court had before, see People v.
    Boyde, 
    758 P.2d 25
    , 38 (Cal. 1988)—that “[t]here was no
    deal.” The district judge emphasized that “it became evident
    upon listening to the testimony of Carl Ellison, the prosecutor
    . . . , Ellison’s defense counsel . . . , and [Boyde’s counsel],
    that there was in fact no ‘secret deal,’ and no undisclosed
    agreement or arrangement of any kind between the prosecutor
    and Ellison.” We can set aside this finding only if it is clearly
    erroneous. See Siripongs v. Calderon, 
    133 F.3d 732
    , 736 (9th
    Cir. 1998).
    4496                        BOYDE v. BROWN
    [1] Here, there was evidence supporting the district court’s
    finding: Both the prosecutor and Ellison’s counsel testified
    before the district court, and both protested vigorously that
    they had reached no agreement. This testimony, which was
    expressly credited by the district court, provides a sufficient
    basis for a finding that no agreement existed.
    Boyde nevertheless points out that the prosecutor and Elli-
    son’s counsel acted with suspicious synchronicity, which he
    believes betrays a secret agreement. When Ellison moved to
    waive a jury trial, the prosecutor joined in the waiver. He
    explained:
    [T]he People would also join in that waiver and this
    is not . . . a slow plea by any stretch of the imagina-
    tion,
    [5] and there are no concessions being made by either
    side, and it will be anticipated a fully contested trial
    down the line on the issue of guilt. As the Court well
    knows, . . . there will be no evidence presented in
    aggravation other than the facts of the crime and the
    special circumstances.
    While . . . I’m not going to come out in court and
    concede something at this point in time—it suggests
    to me that at some point in time the law is going to
    require the Court—will not put the Court in a posi-
    tion to come back with a finding of death in this
    case. . . .
    5
    A “slow plea,” or slow plea of guilty, is “an agreed-upon disposition
    of a criminal case via any one of a number of contrived procedures which
    does not require the defendant to admit guilt but results in a finding of
    guilt on an anticipated charge and, usually, for a promised punishment.”
    People v. Tran, 
    199 Cal. Rptr. 539
    , 540 n.2 (1984). For instance, the par-
    ties could agree to submit the case on the transcript of a preliminary hear-
    ing containing only testimony implicating the defendant.
    BOYDE v. BROWN                           4497
    I think it is not part of the negotiations for the jury
    waiver, or anything else. It is just an understanding
    that there will be no further evidence of aggravation,
    and that as I interpret the factors . . . the Court will
    be required as a matter of law, to come back if, in
    fact, special circumstances are found, . . . with life
    without parole . . . .
    Ellison’s counsel then stated, “Mr. Ellison will testify.”
    Boyde finds it suspicious that the prosecutor signaled to the
    district court that he would not pursue the death penalty
    against Ellison shortly after Ellison waived his jury trial right
    and just before Ellison indicated he would testify. In addition,
    he argues that the words “negotiations” and “understanding”
    suggest the prosecutor did so as a result of an agreement with
    Ellison.
    While the prosecutor’s prompt assent to Ellison’s jury
    waiver, as well as some of the statements he made to the trial
    court, may have been sufficient to support a finding that an
    agreement existed, neither the words nor the circumstances
    compel such a finding in the teeth of contrary testimony from
    both the prosecutor and Ellison’s attorney. The prosecutor’s
    words and actions can be explained by circumstances other
    than the existence of an agreement.
    As to the prosecutor’s joining in the jury waiver, the record
    contains evidence that the prosecution had independent rea-
    sons for wanting to try Ellison’s case to the court. Trying
    Boyde and Ellison to separate juries would have significantly
    complicated the prosecutor’s task by requiring him to try a
    two-jury case, something he had never done before. This
    would cause a number of complications, ranging from the
    mundane (how do you accommodate two juries in the court-
    room?) to the critical (how do you coherently present the evi-
    dence admissible against only one defendant, particularly if
    that would require dividing a single witness’s testimony?). By
    4498                     BOYDE v. BROWN
    joining in Ellison’s jury trial waiver, the prosecutor avoided
    these issues.
    There is also a plausible explanation for the prosecutor’s
    suggestion that he would not seek the death penalty for Elli-
    son: It had been the prosecution’s theory all along that Boyde
    was the major culprit in Gibson’s kidnaping and murder, and
    Ellison was the less-culpable follower. Thus, the prosecution
    had filed a statement of aggravation in Boyde’s case, as it was
    required to do as a prerequisite for presenting aggravating
    facts in support of the death penalty, but had filed no such
    statement as to Ellison. By advising the court that the death
    penalty would probably not be appropriate for Ellison, the
    prosecutor simply reassured the trial judge that, by granting
    the uncontested motion for a bench trial, the judge would not
    put himself in the position of making the life-and-death deci-
    sion as to Ellison.
    For their part, Ellison and his counsel had perfectly legiti-
    mate reasons—independent of the prosecution’s preferences
    —for waiving a jury trial and having Ellison testify. Because
    Ellison was being tried with Boyde, it was likely that Elli-
    son’s jury would hear testimony that incriminated only
    Boyde, but could result in prejudice against Ellison. Ellison’s
    counsel was also concerned that the jury might be moved by
    passion about a crime that was well-publicized in the commu-
    nity. As Ellison’s counsel put it, he felt confident that the trial
    judge would “look at the facts and not the emotion.”
    It is clear from the record that Ellison’s counsel and the
    prosecutor had discussed Ellison’s decision to waive a jury.
    Quite likely, during the course of these discussions, the law-
    yers would have realized that they had certain common inter-
    ests: The prosecutor wanted to make the best possible case
    against Boyde as the triggerman, while Ellison’s counsel had
    every reason to shift the major blame onto Boyde and make
    his own client out to be the less culpable actor. But the fact
    that they subsequently acted consistent with those interests
    BOYDE v. BROWN                             4499
    does not necessarily mean they did so pursuant to an agree-
    ment that the prosecutor would not seek the death penalty
    against Ellison if he testified against Boyde.
    [2] The district judge, who heard live testimony from Elli-
    son’s counsel and the prosecutor, emphatically found that no
    secret deal existed; for the reasons explained, this finding is
    not clearly erroneous. Because there was no agreement to dis-
    close, the district court correctly rejected Boyde’s Brady
    claim.
    Competence
    A
    Boyde contends that evidence he gathered after trial proves
    he was not competent during his trial. See Steinsvik v. Vin-
    zant, 
    640 F.2d 949
    , 954 (9th Cir. 1981) (“[E]ven if the evi-
    dence before the trial judge was insufficient to raise a good
    faith doubt with respect to [defendant]’s competency, he
    would still be entitled to relief if it now appears that he was
    in fact incompetent.”).6
    [3] An individual is competent to stand trial if “he has suf-
    ficient present ability to consult with his lawyer with a reason-
    able degree of rational understanding—and . . . he has a
    6
    Boyde’s claim that he was incompetent to stand trial is a “substantive”
    incompetence claim. This is different from what we have termed a “proce-
    dural” incompetence claim, see Davis v. Woodford, 
    384 F.3d 628
    , 644
    (9th Cir. 2004), that the trial court should have held a hearing to determine
    whether the defendant was competent, see Odle v. Woodford, 
    238 F.3d 1084
    , 1087 (9th Cir. 2001) (“We have held that a trial judge must conduct
    a competency hearing whenever the evidence before him raises a bona
    fide doubt about the defendant’s competence to stand trial, even if defense
    counsel does not ask for one.”). Boyde does not argue that the record
    before the trial court was sufficient to give rise to any duty for it to hold
    a competency hearing; he relies instead on new evidence that he claims
    shows him to have been incompetent.
    4500                   BOYDE v. BROWN
    rational as well as factual understanding of the proceedings
    against him.” Dusky v. United States, 
    362 U.S. 402
    , 402
    (1960) (per curiam) (internal quotation marks omitted); see
    also Odle v. Woodford, 
    238 F.3d 1084
    , 1089 (9th Cir. 2001)
    (“[C]ompetence to stand trial does not consist merely of pas-
    sively observing the proceedings. Rather, it requires the men-
    tal acuity to see, hear and digest the evidence, and the ability
    to communicate with counsel in helping prepare an effective
    defense.”). On federal habeas, a petitioner is “entitled to an
    evidentiary hearing on the issue of competency to stand trial
    if he presents sufficient facts to create a real and substantial
    doubt as to his competency.” Boag v. Raines, 
    769 F.2d 1341
    ,
    1343 (9th Cir. 1985).
    Boyde tried to meet this burden by offering the affidavits
    of Scilla Ballas, a psychotherapist, and Dr. George Woods, a
    psychiatrist, who examined him roughly ten years after his
    trial. Each of them concluded that Boyde suffers from various
    personality disorders and mental deficiencies. The question is
    whether their conclusions suffice to raise a real and substan-
    tial doubt about Boyde’s competence at trial. The district
    court did not believe so and thus declined to hold an evidenti-
    ary hearing on the issue. We review this decision de novo. 
    Id. at 1343
    .
    Ballas’s affidavit does little to suggest that Boyde was
    incompetent. She concludes Boyde “suffered from low self
    esteem, poorly developed intellectual functioning, and a con-
    flicted, confused sense of identity,” and that he suffered from
    depression, but she never explains how any of these disorders
    relate to Boyde’s competency. Nor does she indicate that
    Boyde’s intelligence was so limited, or his depression so
    severe, as to impede his ability to understand the proceedings
    against him or assist his counsel in presenting a defense.
    Ballas also found that Boyde responded to stressful events
    with “psychic numbing,” which “modulate[s] the experience
    of extreme, harsh emotional states.” But being numb to the
    BOYDE v. BROWN                       4501
    stress of a trial is different from not understanding it, and even
    farther from being unable to assist with the defense. Again,
    Ballas does not offer any reason to believe that Boyde’s
    numbing rendered him incompetent to stand trial.
    Like Ballas, Dr. Woods describes a variety of psychologi-
    cal problems that Boyde most likely suffered at trial. For
    instance, Woods notes that Boyde “continued to exhibit
    symptoms of major depression.” These problems, like those
    Ballas describes, do not give rise to a substantial doubt about
    whether Boyde was competent to stand trial.
    Woods also asserts that Boyde “began to exhibit paranoid
    delusions” while awaiting trial. Paranoid delusions may in
    some circumstances render an individual incompetent to stand
    trial: If a defendant believed his counsel was out to get him,
    it is questionable whether he could cooperate in preparing a
    defense. However, Boyde’s delusions were not related to his
    counsel, or indeed to any aspect of his trial. Boyde “was
    obsessed with checking his bedding, his food and drinks, and
    making sure that officers didn’t ‘plant’ anything on him.”
    These sorts of delusions, while serious, do not obviously limit
    Boyde’s ability to interact with his counsel, whom he appar-
    ently did not fear, nor do they indicate that Boyde failed to
    understand the proceedings against him.
    Nevertheless, Woods opines that Boyde’s “symptoms of
    psychosis, paranoid delusions and biological depressive mani-
    festations precluded him from rationally assisting his attorney
    in developing strategies for his defense.” Whatever the merit
    of this conclusion in light of the observations on which it is
    based, cf. Williams v. Woodford, 
    384 F.3d 567
    , 609 (9th Cir.
    2004) (finding it significant that “[t]he declarations do not
    describe how [defendant]’s probable mental impairment inter-
    fered with his understanding of the proceedings against him
    or with his ability to assist counsel in presenting a defense”),
    Woods’s conclusion relies on interviews he conducted with
    Boyde in 1993, a full decade after Boyde’s murder trial.
    4502                      BOYDE v. BROWN
    “[W]e disfavor [such] retrospective determinations of incom-
    petence, and give considerable weight to the lack of contem-
    poraneous evidence of a petitioner’s incompetence to stand
    trial.” 
    Id. at 608
    .7
    [4] All of the contemporaneous evidence suggests that
    Boyde was competent. Prior to trial, Boyde had been exam-
    ined by two psychologists, Dr. Linda Waters and Dr. Ronald
    Offenstein. Dr. Waters examined Boyde when he was arrested
    in connection with Gibson’s murder. She concluded that
    Boyde’s “thought patterns, and other test results, do not sug-
    gest central nervous system dysfunction, or ‘minimal brain
    damage.’ ” Nor did Boyde “show disordered, illogical think-
    ing characteristic of psychosis.”
    Boyde’s other psychological expert, Dr. Offenstein, had
    been retained by the defense to determine whether Boyde had
    the “ability to cooperate with Counsel in the presentation of
    a defense.” Offenstein testified that “the issues of cooperation
    with counsel[ ] were not relevant” to Boyde’s case. Offenstein
    explained that Boyde is “in the category of what we call a
    character disorder.” That is, “[h]e’s not psychotic, he is not so
    greatly disturbed that he has no control of his thought pro-
    cesses; but . . . he is not really very well put together . . . .”
    While these contemporaneous psychological observations
    cast doubt on Woods’s retrospective claims, perhaps the most
    telling evidence that Boyde was competent at trial is that nei-
    ther defense counsel—who would have had every incentive to
    point out that his client was incapable of assisting with his
    defense—nor the trial court even hinted that Boyde was
    7
    We have been willing to examine “retrospective competency determi-
    nations” when “it is possible to make an accurate retrospective evalua-
    tion,” such as “by consulting contemporaneous medical reports.”
    Williams, 384 F.3d at 609-10. The only reports produced around the time
    of Boyde’s trial were done by Boyde’s psychological experts, and neither
    of them concluded that Boyde was incompetent. See pages 4502-03 infra.
    BOYDE v. BROWN                      4503
    incompetent. See Hernandez v. Ylst, 
    930 F.2d 714
    , 718 (9th
    Cir. 1991); cf. Williams, 
    384 F.3d at 608
     (“We find especially
    relevant defense counsel’s opinion that [defendant] was com-
    petent to stand trial.”). This is not for lack of opportunity to
    observe him: Boyde testified on his own behalf. Though his
    testimony spans over 300 pages of trial transcript, Boyde can
    point to nothing in it—or anywhere else in the record—
    suggesting he was not completely aware of what was going
    on. Cf. Boag, 
    769 F.2d at 1343
     (“In cases finding sufficient
    evidence of incompetency, the petitioners have been able to
    show either extremely erratic and irrational behavior during
    the course of the trial, or lengthy histories of acute psychosis
    and psychiatric treatment.” (citations omitted)).
    [5] Given the abundant evidence that Boyde was competent
    at trial, Dr. Woods’s retrospective assertion to the contrary
    does not provide a substantial basis for questioning Boyde’s
    competence. The district court did not err in declining to hold
    an evidentiary hearing on this issue.
    B
    Boyde argues that his counsel was ineffective in failing to
    request a competency hearing before trial. Because the evi-
    dence indicates that Boyde was competent to stand trial, we
    reject this claim. See Davis, 
    384 F.3d at 647
    .
    Actual Innocence
    A
    Boyde’s new mental health evidence does double duty. In
    addition to supporting his argument that he was incompetent,
    Boyde contends it proves he was incapable of forming the
    intent required for first-degree murder: As a result of his
    “neurological, emotional, and psychological impairments,” he
    “lacked the mental capacity to control or premeditate his
    actions or to form the requisite criminal intent for the com-
    4504                        BOYDE v. BROWN
    mission of capital murder.” Even if he killed Gibson, that is,
    Boyde claims he is innocent of first-degree murder.
    Boyde does not suggest that the evidence presented at trial
    was insufficient to support his conviction. Cf. Jackson v. Vir-
    ginia, 
    443 U.S. 307
    , 324 (1979) (holding that a defendant is
    “entitled to habeas corpus relief if it is found that upon the
    record evidence adduced at the trial no rational trier of fact
    could have found proof of guilt beyond a reasonable doubt”).
    Instead, he argues that evidence outside of the trial record
    establishes that he is innocent. His argument is therefore a
    “freestanding” actual innocence claim. Carriger v. Stewart,
    
    132 F.3d 463
    , 476 (9th Cir. 1997) (en banc) (citing Herrera
    v. Collins, 
    506 U.S. 390
     (1993)). The standard for establish-
    ing such a claim on habeas review is “ ‘extraordinarily
    high.’ ” 
    Id.
     (quoting Herrera, 
    506 U.S. at 417
    ). Boyde “must
    go beyond demonstrating doubt about his guilt, and must
    affirmatively prove that he is probably innocent.” Id.8
    To support his claim, Boyde points to Dr. Woods’s affida-
    vit, which indicates that, as a result of psychological trauma
    in his childhood, Boyde experiences “disassociation,” an “im-
    mediate psychological response to an intolerable experience”
    in which an individual “ ‘dis-associate[s]’ the normally inte-
    grated aspects of the consciousness, including functions such
    8
    Boyde contends that we should instead apply Jackson’s standard of
    review and ask whether, in light of his mental health evidence, a rational
    trier of fact could convict him. See

    . He claims that Her-
    rera was concerned only with claims of actual innocence “based on newly
    discovered evidence presented in successive habeas petitions, not to peti-
    tions in which the merits are reviewed for the first time and which are not
    based on new evidence.” Apparently he believes that, because his mental
    health evidence describes him at the time of the crime, it is not “new evi-
    dence.” However, it is clear that “the sufficiency of the evidence review
    authorized by Jackson is limited to ‘record evidence.’ ” Herrera, 
    506 U.S. at 402
     (quoting Jackson, 
    443 U.S. at 318
    ). Boyde’s mental health evidence
    was not presented at trial and is thus not “record evidence.” Nor is it sig-
    nificant that Boyde raises his claim in his first federal habeas petition;
    Herrera’s analysis concerns the limits of our habeas jurisdiction generally.

    as memory, perception, motivation, and judgment” (alteration
    added). Woods notes that disassociation can lead to “behavior
    which is sudden, unpremeditated and uncharacteristic of the
    individual,” and concludes that, at the time of his crimes,
    Boyde was “in a depressed, dissociated state that precluded
    him from appreciating the nature and gravity of his actions.”
    [6] This affidavit is insufficient to establish Boyde’s inno-
    cence. “Because psychiatrists disagree widely and frequently
    on what constitutes mental illness, a defendant could . . .
    always provide a showing of factual innocence by hiring psy-
    chiatric experts who would reach a favorable conclusion.”
    Harris v. Vasquez, 
    949 F.2d 1497
    , 1515 (9th Cir. 1990) (quot-
    ing Ake v. Oklahoma, 
    470 U.S. 68
    , 81 (1985)) (internal quota-
    tion marks omitted). Accordingly, “it is clear that the mere
    presentation of new psychological evaluations . . . does not
    constitute a colorable showing of actual innocence.” Id. at
    1516; see also Griffin v. Johnson, 
    350 F.3d 956
    , 965 (9th Cir.
    2003). We therefore reject Boyde’s actual innocence claim.
    B
    Boyde argues that his counsel was ineffective in failing to
    present a defense of mental incapacity to premeditate at his
    trial. However, Boyde’s counsel had access to statements
    Boyde and Ellison made to the police that indicated Boyde
    knew exactly what he was doing during the Baker and Gibson
    robberies. He also had retained two experts, including one
    who was asked to look for possible defenses, who examined
    Boyde and determined that he was sufficiently in control of
    his actions. See Hendricks v. Calderon, 
    70 F.3d 1032
    ,
    1038-39 (9th Cir. 1995) (“In general, an attorney is entitled to
    rely on the opinions of mental health experts in deciding
    whether to pursue an insanity or diminished capacity
    defense.”). In view of this evidence, Boyde’s counsel was not
    ineffective in choosing to devote his time and resources to
    other aspects of the case.
    4506                       BOYDE v. BROWN
    Batson Claim
    The prosecutor used a peremptory challenge to remove
    Ernestine Perdue, a black woman, from the jury. Boyde
    claims that this challenge violated the Fourteenth Amendment
    because it was based on Perdue’s race.9
    In Batson v. Kentucky, 
    476 U.S. 79
     (1986), the Supreme
    Court articulated a three-step process for considering claims
    of racial bias in the exercise of peremptory challenges. The
    defendant must first make a prima facie showing that “the
    prosecutor used [peremptory challenges] to exclude . . .
    veniremen [of defendant’s race] from the petit jury on account
    of their race.” Batson, 
    476 U.S. at 96
    . If the defendant makes
    such a showing, “the burden shifts to the State to come for-
    ward with a neutral explanation for challenging [the] jurors.”
    
    Id. at 97
    . Finally, the trial court has “the duty to determine if
    the defendant has established purposeful discrimination.” 
    Id. at 98
    .
    A
    The state does not dispute that Boyde made a prima facie
    showing of discrimination in the selection of his jury. In any
    event, the trial court asked the prosecutor to explain his chal-
    lenge to Perdue when Boyde’s counsel objected to it; after the
    prosecutor did so, the court “ruled on the ultimate question of
    intentional discrimination” by concluding that the challenge
    was not racially motivated. See Hernandez v. New York, 
    500 U.S. 352
    , 359 (1991) (plurality op.). At that point, “the pre-
    liminary issue of whether the defendant had made a prima

    Boyde also requests that we expand the certificate of appealability
    (“COA”) to include similar claims with respect to four other jurors. See
    Slack v. McDaniel, 
    529 U.S. 473
    , 481-82 (2000) (applying AEDPA’s
    COA requirement to appeals, like this one, that were filed after April 24,
    1996). Because he has not shown that “reasonable jurists would find the
    district court’s assessment of [these] constitutional claims debatable or
    wrong,” 
    id. at 484
    , we decline to do so.

    facie showing [became] moot.” Id.; see also United States v.
    Bishop, 
    959 F.2d 820
    , 824 (9th Cir. 1992).
    B
    The prosecutor offered a number of explanations for chal-
    lenging Perdue:
    My problem with Mrs. Perdue is that if she were
    a White juror I would have no question that I would
    excuse her; and, the only reason I even considered
    keeping her was because she was Black and I
    thought to myself I shouldn’t have to be faced with
    that choice, that I should be able to exercise a
    peremptory challenge regardless of what a person’s
    color was.
    I had an experience about six months ago where
    I prosecuted a murder of a wom[a]n about the same
    age as Mrs. Perdue, who was also a grandmother
    who was also in the Seventh-[D]ay Adventist
    Church, who remarkably was similar to Mrs. Perdue
    in that I think she was involved in the church welfare
    work with the Seventh-Day Adventist Church and
    was very highly thought of in the apartment complex
    in which she lived. Apparently she was much like an
    aunt to all the people there or, you know, the world’s
    grandmother. And, I would have a hard time believ-
    ing that someone like that—and I equate that with
    Mrs. Perdue as well—would be able to, when it
    came right down to it, vote for the death penalty.
    And, I believe she would be swayed by that, and I
    am just uncomfortable with it.
    I’m also uncomfortable with her because there
    were some hesitations that I saw when she was dis-
    cussing the death penalty as opposed to life without
    possibility of parole. I did notice some hesitation
    4508                   BOYDE v. BROWN
    there, but that is not my primary difficulty with Mrs.
    Perdue.
    I am also somewhat leary, she’s a mother, a
    grandmother, she did come from Perris. I have had
    bad experiences in my past with jurors from Perris
    and I am distrustful with certain areas of that com-
    munity. As well as she having moved as much as
    she’s moved within the last few years, to Palm
    Springs, to Needles and back to Riverside indicating
    a more transient type person than I would like to
    have on a case like this.
    Also, her appearance; large, heavy-set, older
    middle-aged wom[a]n, just—just does not strike a
    responsive c[h]ord to me and that is why I excused
    her. I can’t say specifically, you know, that it was
    this answer or that answer to this particular question
    that indicated that she was biased or would be unfair,
    but it was just the whole persona, and it is not
    because she’s Black.
    We must determine whether these explanations were race-
    neutral. See United States v. McCoy, 
    23 F.3d 216
    , 217 (9th
    Cir. 1994) (per curiam) (“Whether the prosecutor’s asserted
    reason for a challenge is race-neutral on its face is a question
    of law reviewed de novo.”); see also Tolbert v. Page, 
    182 F.3d 677
    , 680 n.5 (9th Cir. 1999) (en banc). To do so, we con-
    sider only the “facial validity of the prosecutor’s explana-
    tion,” Purkett v. Elem, 
    514 U.S. 765
    , 768 (1995) (per curiam)
    (quoting Hernandez, 
    500 U.S. at 360
    ) (internal quotation
    marks omitted), not its persuasiveness. That is, “[u]nless a
    discriminatory intent is inherent in the prosecutor’s explana-
    tion, the reason offered will be deemed race neutral.” 
    Id.
    (quoting Hernandez, 
    500 U.S. at 360
    ) (internal quotation
    marks omitted).
    [7] Four of the prosecutor’s reasons are plainly race-
    neutral: Perdue’s grandmotherliness, her hesitations, her
    BOYDE v. BROWN                            4509
    “transient” background and her “persona.” But Boyde argues
    that one of the prosecutor’s explanations requires closer scru-
    tiny. The prosecutor stated he was “distrustful with certain
    areas” of Perris. We have recognized that residence can be
    used as a proxy for race, see Bishop, 
    959 F.2d at 825-26
    , and
    thus that striking jurors on the basis of their residence might
    not be race-neutral.
    In Bishop, the prosecutor excused from the jury a black eli-
    gibility worker from Compton because he believed the struck
    juror was “likely to take the side of those who are having a
    tough time, aren’t upper middle class, and probably believes
    that police in Compton in South Central L.A. pick on black
    people.” 
    Id. at 822
    . We noted that his explanation relied on a
    “group-based presupposition[ ] applicable in all criminal trials
    to residents of poor, predominantly black neighborhoods,” 
    id. at 825
    ; it “both reflected and conveyed deeply ingrained and
    pernicious stereotypes.” Because the prosecutor used resi-
    dence “as a surrogate for racial stereotypes,” 
    id. at 826
    , his
    explanation based on residence was not race-neutral.
    [8] In this case, by contrast, the prosecutor’s comment
    about Perris did not rely on any group-based presupposition.
    The prosecutor did not mention race or draw on any racial ste-
    reotype. There is nothing in the record to suggest that the
    prosecutor’s bad experiences with people from Perris were
    tied to race. Nor did Boyde offer anything at the time of trial
    or in his post-conviction proceedings to show that the prose-
    cutor’s reference to Perris should be understood as a surrogate
    for race. There is no “discriminatory intent . . . inherent in the
    prosecutor’s explanation,” Purkett, 
    514 U.S. at 767
     (quoting
    Hernandez, 
    500 U.S. at 360
    ) (internal quotation marks omit-
    ted), and thus his use of residence, like his other explanations,
    was race-neutral.10 Because the prosecutor met his burden of
    10
    Boyde argues that the prosecutor’s use of residence was nonetheless
    invalid because the prosecutor did not explain how Perdue’s residence was
    relevant to the facts of Boyde’s trial. Bishop did suggest that the presence
    4510                         BOYDE v. BROWN
    articulating a race-neutral explanation for challenging Perdue,
    the trial court properly proceeded to the third step of the
    Batson analysis.
    C
    The trial judge found that the prosecutor “is color blind in
    the exercise of his peremptory challenges. It is not on the
    basis of color.” After further discussion with the parties, he
    reiterated this view: “It is clear that it is not based upon
    color.” We review this factual finding for clear error. See Tol-
    bert, 
    182 F.3d at
    680 n.5.
    The “ultimate burden of persuasion regarding racial moti-
    vation rests with, and never shifts from, the opponent of the
    strike.” Purkett, 
    514 U.S. at 768
    . A defendant cannot satisfy
    his “ultimate burden” if he does not offer any evidence to
    or absence of a “nexus between the [challenged] jurors’ [residence] . . .
    and their possible approach to the specific trial” was significant in deter-
    mining whether the use of residence was race-neutral. 
    959 F.2d at 825
    . It
    noted, for instance, that residence may properly be “utilized as a link con-
    necting a specific juror to the facts of the case,” such as when a juror is
    challenged because he is from the same neighborhood as a potential wit-
    ness. 
    Id. at 826
    . The theory behind Bishop’s argument seems to be that an
    unexplained use of residence may actually be a pretext for racial discrimi-
    nation. 
    Id. at 825-26
    .
    The Supreme Court has since made clear, however, that we do not con-
    sider whether an explanation is pretextual when we decide, in Batson’s
    second step, whether it is race-neutral. We consider only whether the
    explanation is facially race-neutral. See Purkett, 
    514 U.S. at 768
    . It may
    be unpersuasive for a prosecutor to use residence without attempting to tie
    it to the facts of the case. A trial court could consider that lack of explana-
    tion when it decides, in Batson’s third step, whether to credit the prosecu-
    tor’s explanation or find that residence was a pretext for what was really
    a race-based challenge. See 
    id.
     (“It is not until the third step that the per-
    suasiveness of the justification becomes relevant.”). To the extent Bishop
    suggests that the race-neutrality of an explanation depends on its persua-
    siveness, it has been effectively overruled by Purkett. See Miller v. Gam-
    mie, 
    335 F.3d 889
    , 900 (9th Cir. 2003) (en banc).
    BOYDE v. BROWN                             4511
    rebut the prosecutor’s race-neutral explanation. Accordingly,
    we must consider “[t]he correctness of the court’s ruling . . .
    in terms of the information that was before [it] at the time that
    the Batson objection was raised.” United States v. Bauer, 
    84 F.3d 1549
    , 1554-55 (9th Cir. 1996).
    [9] Boyde did not explain to the trial court why it should
    disbelieve the prosecutor’s race-neutral explanations. His
    counsel agreed that the prosecutor was “acting in good faith,”
    and stated that he did not “believe that [the prosecutor] is
    standing before the Court contriving reasons why he wishes
    to exercise a peremptory.”11 Because he did not rebut the
    prosecutor’s race-neutral explanations, Boyde failed to carry
    his burden of persuasion. We have no basis for second-
    guessing the trial court’s determination.
    Evidence of Prior Crimes
    A
    The prosecution presented evidence that, in 1976, Boyde
    had robbed the same 7-Eleven station that was robbed in the
    Gibson robbery. The clerk who had been on duty at the time
    of the 1976 robbery testified that Boyde and an accomplice
    demanded money from him at gunpoint and stole various
    items, including cigarettes. They forced the clerk to get into
    the trunk of his car, which they then stole and drove out of
    town before releasing him a few hours later.
    Boyde suggests the prosecution used this evidence to per-
    suade the jury that he was a bad person, who was thus likely
    11
    The theory on which he rested his challenge was that, “even giv[ing]
    full credit to the Prosecutor’s stated reasons, . . . the rights of my client
    to be tried by a jury of his peers, which would include a representative
    number of blacks where possible, where appropriate, would outweigh the
    reasons as propounded by the District Attorney.” That is, he believed that
    striking Perdue on race-neutral grounds was improper, as it resulted in a
    jury that was not racially balanced.
    4512                    BOYDE v. BROWN
    to have shot Gibson. He argues that the evidence of his earlier
    robbery was irrelevant to any issue other than his character,
    and that its admission violated due process. See McKinney v.
    Rees, 
    993 F.2d 1378
    , 1384-85 (9th Cir. 1993).
    A habeas petitioner bears a heavy burden in showing a due
    process violation based on an evidentiary decision. “Evidence
    introduced by the prosecution will often raise more than one
    inference, some permissible, some not.” Jammal v. Van de
    Kamp, 
    926 F.2d 918
    , 920 (9th Cir. 1991). In such cases, “we
    must rely on the jury to sort [the inferences] out in light of the
    court’s instructions.” 
    Id.
     Admission of evidence violates due
    process “[o]nly if there are no permissible inferences the jury
    may draw” from it. 
    Id.
    Boyde tries to meet this standard by positing that the “only
    conceivable inference [from his involvement in a prior
    robbery-kidnaping] was the improper one that [his] prior acts
    made him more likely to be the instigator and triggerman.”
    That is one possible inference, but it is not the only one.
    The prosecution had to prove that Boyde committed the
    Gibson robbery. One typical—and constitutionally
    permissible—way to do this is to show that the crime shared
    certain characteristics—a modus operandi—with other crimes
    that Boyde had committed. See, e.g., United States v. Sidman,
    
    470 F.2d 1158
    , 1166 (9th Cir. 1972). Therein lies the rele-
    vance of the 1976 robbery: The fact that Boyde had previ-
    ously robbed the same 7-Eleven store, at gun point, with an
    accomplice, in a crime that involved kidnaping the clerk,
    makes it more likely that he was involved when a crime shar-
    ing those characteristics occurred later. See McKinney, 
    993 F.2d at 1382
     (noting that evidence is relevant if it “tend[s] to
    make any fact relevant to the[ ] elements [of the crime] more
    or less probable”). That is the basis on which the trial court
    BOYDE v. BROWN                           4513
    admitted the evidence; the court explained: “It goes to the
    identity. . . . [I]t is unique, it is unus[u]al, and it is so similar.”12
    Boyde responds that evidence of the 1976 robbery was “not
    necessary to show modus operandi or other indicia of identity,
    as Boyde’s identity and presence during the [Gibson] offense
    was undisputed.” At trial, Boyde took the stand in his defense
    and admitted he was with Ellison at the time of the robbery,
    denying only that he had been the one to shoot Gibson. When
    the trial court admitted evidence of the earlier robbery during
    the prosecution’s case in chief, though, Boyde had not yet tes-
    tified, nor was it clear what defense his counsel would pre-
    sent. Moreover, Boyde claimed that he had waited in the car
    while Ellison went into the store to get cigarettes, and that
    Ellison decided to rob the store on his own. The prosecution’s
    evidence undercut this claim by showing that the robbery was
    similar to Boyde’s previous robbery. In any event, as the trial
    court well understood, the fact that the prosecutor had strong
    evidence to prove that Boyde had committed the robbery does
    not mean the jury should not hear other evidence, as “we
    don’t know [in advance] what the jury is going to believe or
    what items of evidence they [will] choose to believe.”
    [10] Because the jury could draw a permissible inference
    from evidence of Boyde’s 1976 robbery, admission of that
    evidence did not violate due process, so long as the jury was
    instructed that it could not draw any improper inferences from
    it. In this case, the trial judge instructed the jury that evidence
    of Boyde’s other crimes “was not received and may not be
    considered by you to prove that he is a person of bad charac-
    ter, or that he has a disposition to commit crimes.” He
    explained to the jury:
    12
    The court also admitted the evidence because it was relevant in deter-
    mining whether Boyde committed the Baker robbery. In that incident, as
    in Boyde’s 1976 robbery, the robber targeted a gas station, used a weapon
    and ultimately kidnaped the clerk.
    4514                   BOYDE v. BROWN
    [E]vidence [of prior crimes] was received and may
    be considered by you only for the limited purpose of
    determining if it tends to show a characteristic
    method, plan or scheme in the commission of crimi-
    nal acts similar to the method, plan or scheme used
    in the commission of the offense in this case, which
    would further tend to show the identity of the person
    who committed the crime, if any, of which the
    defendant is accused.
    [11] Because we must presume that the jury followed its
    instructions to consider only the permissible inference that
    Boyde committed the Gibson robbery, we conclude that
    admission of evidence about the prior robbery did not violate
    due process.
    B
    The 1976 robbery was not the only one of Boyde’s past
    crimes the jury heard about. When Boyde testified, his own
    counsel questioned him about his prior robberies, and the
    prosecutor cross-examined him vigorously about the details of
    those crimes. Boyde argues that his counsel was ineffective in
    allowing the jury to hear this evidence.
    [12] He suggests that counsel’s error was failing to object
    to the prosecutor’s cross-examination. In some circumstances,
    it would be ineffective for counsel not to object to evidence
    of the defendant’s prior crimes. See, e.g., Crotts v. Smith, 
    73 F.3d 861
    , 866 (9th Cir. 1996). To succeed on such a claim,
    however, the defendant must show that he was prejudiced by
    counsel’s error. This, in turn, requires a showing that, had his
    counsel objected, “it is reasonable that the trial court would
    have granted [the objection] as meritorious.” Wilson v. Henry,
    
    185 F.3d 986
    , 990 (9th Cir. 1999). In this case, Boyde can
    make no such showing: An objection would have failed
    because his counsel opened the door for the cross-
    examination by bringing up the crimes during direct examina-
    BOYDE v. BROWN                      4515
    tion. Boyde’s counsel was ineffective only if he was ineffec-
    tive in bringing up the prior robberies in the first place.
    In a declaration given shortly after Boyde’s trial, his coun-
    sel explained his decision to question Boyde on his prior
    crimes. After Ellison testified and fingered Boyde as Gibson’s
    killer, Boyde decided that he wanted to testify, and he insisted
    on doing so against his counsel’s advice. By testifying, Boyde
    would put his credibility at issue, and, under California law,
    certain evidence of prior crimes could be admitted to impeach
    him. Recognizing this, Boyde’s counsel concluded that Boyde
    “would be better served in meeting the question of his priors
    head-on and dealing with them forthrightly in front of the
    jury.” This is precisely the sort of tactical decision that coun-
    sel is expected to make at trial. Cf. Lang v. Callahan, 
    788 F.2d 1416
    , 1418 (9th Cir. 1986) (finding that “counsel’s stra-
    tegic decision to stipulate [the admissibility of certain state-
    ments in the hope that the deputy prosecutor would agree to
    admit certain other statements] falls well within the range of
    reasonable professional assistance”).
    Boyde argues that his counsel’s strategy was nonetheless
    unreasonable because he was mistaken that evidence of
    Boyde’s prior convictions could be admitted on cross-
    examination. 
    Cal. Evid. Code § 788
     provides that, “[f]or the
    purpose of attacking the credibility of a witness, it may be
    shown by the examination of the witness . . . that he has been
    convicted of a felony.” But 
    Cal. Evid. Code § 352
     gives the
    trial judge discretion to exclude evidence that would other-
    wise be admissible “if its probative value is substantially out-
    weighed by the probability that its admission will . . . create
    substantial danger of undue prejudice.” Reading these two
    provisions together, the California Supreme Court held that,
    when a defendant takes the stand in his own defense, the trial
    judge has discretion “to exclude evidence of prior felony con-
    victions when their probative value on credibility is out-
    weighed by the risk of undue prejudice.” People v. Beagle,
    
    492 P.2d 1
    , 7-8 (Cal. 1972).
    4516                        BOYDE v. BROWN
    Beagle provided a few guideposts in how a trial court
    should exercise this discretion. It offered the “rule of thumb”
    that “convictions which rest on dishonest conduct relate to
    credibility whereas those of violent or assaultive crimes gen-
    erally do not.” 
    Id.
     (quoting Gordon v. United States, 
    383 F.2d 936
    , 940 (D.C. Cir. 1967)) (internal quotation marks omitted).13
    In addition, the trial court should consider the “nearness or
    remoteness of the prior conviction.” 
    Id.
     (quoting Gordon, 
    383 F.2d at 940
    ). And, the court should disfavor use of a prior
    conviction if it is “for the same or substantially similar con-
    duct for which the accused is on trial.” 
    Id.
     (quoting Gordon,
    
    383 F.2d at 940
    ).14
    Boyde argues that because his “prior robberies involved no
    ‘dishonest’ acts,” they would have been excluded under Bea-
    gle. Although he is correct that robbery is assaultive, it also
    involves stealing, an act of dishonesty that bears on credibil-
    ity. The California Supreme Court had therefore determined
    13
    After Boyde’s trial, the California Constitution was amended to
    broaden the circumstances in which evidence of prior felony convictions
    can be admitted. See Cal. Const. art. I, § 28(f); see also People v. Castro,
    
    696 P.2d 111
    , 113 (Cal. 1985) (interpreting section 28(f) as authorizing
    “the use of any felony conviction which necessarily involves moral turpi-
    tude, even if the immoral trait is one other than dishonesty,” subject to the
    trial court’s discretion to exclude unduly prejudicial evidence under 
    Cal. Evid. Code § 352
    ). Because our concern is what Boyde’s counsel did
    before and during trial, we consider California law as it existed prior to
    this constitutional amendment.
    14
    Gordon, the case on which Beagle principally relied, emphasized that
    it did not “place[ ] any limitations on established rules which permit evi-
    dence of prior criminality to show a ‘pattern’ of offenses.” 
    383 F.2d at
    940
    n.10. Rather, it limited the use of prior convictions for the purposes of
    impeaching a defendant’s credibility. See 
    id. at 940
    ; see also People v.
    Rist, 
    545 P.2d 833
    , 839 (Cal. 1976) (criticizing the trial court for allowing
    the prosecution to impeach a robbery defendant using evidence of a prior,
    similar robbery). With the exception of the 1976 robbery, see pages
    4516-17 supra, the prosecution here did not argue, nor did Boyde’s coun-
    sel believe, that Boyde’s prior robberies were admissible because they
    established a modus operandi. Instead, Boyde’s counsel believed they
    would be admitted under Beagle to impeach Boyde.
    BOYDE v. BROWN                      4517
    that robbery “is a crime which is both larcenous and assaul-
    tive, and thus bears in part on the perpetrator’s integrity and
    veracity.” People v. Rist, 
    545 P.2d 833
    , 839 (Cal. 1976).
    Boyde’s robberies were also relatively recent, having been
    committed only five years before the trial.
    The one basis on which the trial judge might have excluded
    the evidence is that Boyde’s prior robberies involved the same
    offense as the robberies for which he was on trial, and thus
    that evidence of the prior crimes might be too prejudicial. But
    while Beagle emphasized that “convictions which are for the
    same crime should be admitted sparingly,” 
    492 P.2d at 8
    (quoting Gordon, 
    383 F.2d at 941
    ), it looked to evidence of
    different crimes as an alternative, 
    id.
     (“Where multiple con-
    victions of various kinds can be shown, strong reasons arise
    for excluding those which are for the same crime . . . .” ); see
    Rist, 
    545 P.2d at 839
     (holding that a trial court abused its dis-
    cretion in admitting evidence of prior robberies in a robbery
    prosecution where the prosecution could have impeached the
    defendant using evidence of other, dissimilar crimes). Here,
    there were no other recent crimes that the prosecutor could
    have used to impeach Boyde.
    In sum, it is unclear how the trial court would have applied
    Beagle to Boyde’s robberies. Because the crimes bore on
    Boyde’s credibility and were relatively recent, and because
    the prosecution had no other crimes it could use to impeach
    Boyde, Boyde’s counsel could reasonably believe that the
    court would have admitted the evidence.
    Moreover, by eliciting testimony about the robberies,
    Boyde’s counsel was able to bolster his argument that Ellison,
    not Boyde, killed Gibson. Boyde had robbed a lot of people,
    but he had never killed anyone. And even though he had pre-
    viously kidnaped gas station attendants, he had always let
    them go without hurting them. The Gibson robbery ended dif-
    ferently, and Boyde’s counsel explained to the jury that the
    reason for this difference was Ellison. He argued:
    4518                   BOYDE v. BROWN
    How is it that Richard Boyde is involved in ten,
    eleven robberies without hurting anybody. Gets out
    here and Dickie Gibson is dead. The only difference
    I submit that stands out . . . is that along with Rich-
    ard Boyde and that orange grove was Carl Franklin
    Ellison who was scared of being caught, who was
    frightened of being identified . . . . Can you say with
    absolute certainty when that first bullet was fired that
    it wasn’t fired by Carl Ellison with his eyes closed
    ...?
    [13] In the exercise of his professional judgment, Boyde’s
    counsel reasonably concluded that the trial court would admit
    evidence of Boyde’s prior crimes. He decided to confront the
    crimes directly, and he even developed them into a theory that
    Ellison must have been the triggerman. This strategy didn’t
    work, but it was not ineffective assistance.
    Cumulative Guilt Phase Error
    Because we find no merit in Boyde’s claims of constitu-
    tional error in the guilt phase of his trial, we also reject his
    contention that he was prejudiced by the cumulative effect of
    the claimed errors.
    Penalty Phase Errors
    Boyde raises a number of claims that his counsel was inef-
    fective during the penalty phase of his trial. To support his
    ineffective assistance claim, Boyde must show both that his
    counsel’s performance fell below the “wide range of profes-
    sionally competent assistance” and that he was prejudiced by
    the deficient performance. Strickland v. Washington, 
    466 U.S. 668
    , 690, 693-94 (1984). We must analyze each of his claims
    separately to determine whether his counsel was deficient, but
    “prejudice may result from the cumulative impact of multiple
    deficiencies.” Cooper v. Fitzharris, 
    586 F.2d 1325
    , 1333 (9th
    BOYDE v. BROWN                      4519
    Cir. 1978) (en banc); see also Harris ex rel. Ramseyer v.
    Wood, 
    64 F.3d 1432
    , 1438-39 (9th Cir. 1995).
    A
    Boyde argues that his counsel failed to investigate mitigat-
    ing childhood abuse, and that he failed to introduce the evi-
    dence that his limited investigation did uncover. Boyde’s
    counsel had retained an investigator to interview potential
    witnesses, and one individual he interviewed was Helen Ken-
    dricks, Boyde’s youngest sister, who ultimately testified on
    Boyde’s behalf at his sentencing. Much of what Kendricks
    discussed with the investigator would become part of her tes-
    timony at trial. One part that did not was her allegation that
    she, Boyde and the other siblings were regularly and violently
    abused by Boyde’s mother and stepfather. She also explained
    that the stepfather had sexually molested the female siblings,
    and that Boyde had been aware of this abuse from an early
    age.
    [14] Boyde’s history of suffering violent physical abuse, as
    well as the family history of sexual abuse he had known about
    growing up, is the sort of evidence that could persuade a jury
    to be lenient. “Evidence regarding social background and
    mental health is significant, as there is a ‘belief, long held by
    this society, that defendants who commit criminal acts that are
    attributable to a disadvantaged background or to emotional
    and mental problems, may be less culpable than defendants
    who have no such excuse.’ ” Douglas v. Woodford, 
    316 F.3d 1079
    , 1090 (9th Cir. 2003) (quoting Boyde v. California, 
    494 U.S. 370
    , 382 (1990) (Boyde’s case on direct review) (quot-
    ing Penry v. Lynaugh, 
    492 U.S. 302
    , 319 (1989) (quoting
    California v. Brown, 
    479 U.S. 538
    , 545 (1987) (O’Connor, J.,
    concurring)))). Because of the importance of background in
    convincing a jury to spare a defendant’s life, the Supreme
    Court has recognized that it is ineffective for counsel to fail
    to present such evidence to the jury. See Williams v. Taylor,
    4520                   BOYDE v. BROWN
    
    529 U.S. 362
    , 390-99 (2000). Boyde’s counsel was deficient
    in failing to do so here.
    [15] As disturbing as counsel’s decision not to present the
    evidence of abuse that he had discovered was his failure to
    follow up on this evidence by investigating what other miti-
    gating evidence might exist. Had counsel asked Kendricks for
    more details about Boyde’s beatings, he would have learned
    how severe they had been. According to Kendricks, on one
    occasion Boyde’s mother beat him with an extension cord;
    when he didn’t cry, she responded by promising that “she was
    going to keep beating him until he cried.” The ensuing abuse
    was so severe that the other children began to cry and pled
    with their mother to quit beating Boyde, but she “just kept
    beating him” until, finally, “one tear trickled out and she
    stopped.” On a different occasion, Boyde’s mother hit him in
    the head with a vase with enough force that “it drew blood
    and he had to get stitches.” Kendricks recalled Boyde being
    “dazed by the blow to his head and . . . stumbling around
    afterwards.” Bad as these beatings were, Boyde’s stepfather
    was “much worse than [Boyde’s] mother as far as beating the
    kids”; he would “beat [them] longer and would beat [them] all
    over the room.”
    Kendricks also explained more about the stepfather’s sex-
    ual abuse of the female siblings, which began for her when
    she was about 11 or 12 years old. None of the siblings was
    comfortable bringing up the sexual abuse with their mother;
    they worried that she would side with her husband, and that
    the consequences of mentioning it would be unpleasant.
    Boyde had participated in discussions among the siblings in
    which they gathered courage to approach their mother about
    it. Eventually, Betty Sauls, another of Boyde’s sisters,
    informed her of the abuse. But, as feared, her mother did not
    believe her, pulled a gun on Sauls and threw her out of the
    house.
    Kendricks emphasized that, if Boyde’s counsel “had asked
    me to describe what it was like growing up in my family and
    BOYDE v. BROWN                      4521
    how it affected [Boyde] and the rest of us, I would have told
    him.” The jury may well have had sympathy for Boyde
    because of his damaged childhood. Yet Kendricks was never
    asked to describe it.
    Kendricks was not the only one of Boyde’s siblings who
    could have testified about his childhood abuse. Sauls
    explained in an affidavit that their mother would beat the chil-
    dren with “anything she could get her hands on—
    straightening combs, water hoses, bricks, brushes, lamps.”
    And Boyde’s oldest sister, Beatrice Will, explained that their
    mother “would beat [Boyde] until he cried, using a switch or
    an extension cord. She would really whip [Boyde]—on his
    back, his butt, anywhere she could hit him. She mostly used
    an extension cord, but would beat you with the first thing she
    got her hands on.” Both Sauls and Will corroborated Ken-
    dricks’s report of frequent sexual abuse.
    [16] Even though Boyde’s counsel was aware of physical
    and sexual abuse by Boyde’s mother and stepfather, he failed
    to investigate that abuse. As a result, he did not discover the
    vast evidence that Boyde had been violently abused, and that
    he knew his sisters had been molested. Because the defen-
    dant’s background is so important in the sentencing process,
    “[i]t is imperative that all relevant mitigation information be
    unearthed for consideration.” Douglas, 
    316 F.3d at 1088
    (quoting Caro v. Calderon, 
    165 F.3d 1223
    , 1227 (9th Cir.
    1999)) (internal quotation marks omitted). The evidence that
    Boyde’s counsel discovered “revealed the need to dig deep-
    er,” 
    id.,
     and his failure to do so fell far short of professional
    standards, see Williams, 
    529 U.S. at 396
     (finding that “trial
    counsel did not fulfill their obligation to conduct a thorough
    investigation of the defendant’s background”); see also Wig-
    gins v. Smith, 
    539 U.S. 510
    , 521-23 (2003).
    The harm caused by counsel’s failure to investigate and
    present evidence of abuse was not just that the jury was
    deprived of relevant information about Boyde’s childhood.
    4522                       BOYDE v. BROWN
    Boyde’s counsel called both Boyde’s mother and stepfather—
    the alleged abusers—to testify during sentencing. We cannot
    fault this decision, as a defendant’s parents will often make
    the most persuasive case to the jury for sparing their son’s
    life. But the evidence he elicited from the parents suggested—
    in stark contrast to what counsel’s own investigation had
    revealed—that Boyde had a normal, non-violent childhood.15
    Boyde’s stepfather explained that Boyde was “a normal
    child just as any other child.” He admitted that he would dis-
    cipline Boyde occasionally using items such as belts, but
    denied any severe beatings. In all, he estimated that he had to
    discipline Boyde on only four occasions. Likewise, when
    Boyde’s mother was asked whether she “raise[d] [Boyde] to
    exhibit violence in any form,” she replied: “No, I didn’t want
    him in no violence, I ain’t never taught him violence at no
    time.”
    The jury, left to wonder how Boyde learned to commit such
    violent acts, could not look to his childhood as an explanation
    —his parents’ testimony and counsel’s deficiency took care of
    that—but must instead have concluded that he grew violent
    despite his childhood. The most likely explanation was pro-
    vided by counsel.
    Boyde’s counsel argued in his closing that Boyde was a
    product of California’s youth and adult corrections system,
    where prisons operate as “schools for crime.” Perhaps that
    explanation could have inspired sympathy for a defendant like
    15
    This testimony was hardly unexpected. In an earlier interview with
    one of Boyde’s investigators, Boyde’s mother described Boyde’s child-
    hood as uneventful. The investigator reported her claims that Boyde’s
    stepfather “helped raise her children and had always treated them good
    and was never a mean stepfather to the children. He gave them money and
    there were no arguments or problems between the children and their step-
    father.” Upon reviewing the investigator’s report, an attorney who assisted
    Boyde’s counsel remarked that she “obviously . . . know[s] or should
    know more than [she] told us.”
    BOYDE v. BROWN                             4523
    Boyde, who had spent much of his life in prison, and we have
    no doubt that this element of counsel’s strategy was within the
    range of reasonable professional assistance. But whatever
    sympathy he hoped to create was quickly extinguished
    through the following argument:
    Now, obviously in this case we can’t put [Califor-
    nia’s penal] institutions on trial, it wouldn’t be
    appropriate to do that here, but I was struck by a
    scene in the movie Helter Skelter. . . . A key point
    in the trial, Charlie Manson got up to argue for him-
    self, his own case, he got up and he said “I am a
    child of your prisons,” he said, “You may blame me
    all you wish, but I was born and raised and taught
    and learned to live and breathe in your institutions,
    your prisons.”
    And Richard Boyde, to a certain extent, is a child
    of your institutions . . . .
    [17] It is difficult to conceive of any possible justification
    for referring to a notorious mass murderer in trying to per-
    suade the jury to spare Boyde’s life, and certainly not one that
    warrants comparing Boyde to that murderer.16 In a consider-
    16
    This was not the only inexplicable reference in the closing. Towards
    the end of his argument, Boyde’s counsel quoted an article by Norman
    Mailer in which Mailer opines that “[a] male leading a dull life, full of
    oppression, who finds himself a little more choked with rage each year,
    will secretly be drawn to capital punishment as a release from the monot-
    ony of his existence.” Thus, counsel suggested, Boyde committed murder
    “just to get a little attention,” and that he wanted to be caught “to destroy
    himself.”
    Boyde’s counsel urged the jury not to help Boyde destroy himself, but
    the harm may already have been done. By informing the jury that, in a
    way, Boyde wanted to die, his counsel “effectively relieved the jurors of
    the heavy responsibility inherent in imposing a sentence of death.” Wade
    v. Calderon, 
    29 F.3d 1312
    , 1332-33 (9th Cir. 1994) (Reinhardt, J., concur-
    ring in part and dissenting in part). Because counsel’s other errors amount
    to ineffective assistance, we need not decide whether this error alone
    would suffice.
    4524                   BOYDE v. BROWN
    able understatement, the district judge remarked: “Although it
    was under the circumstances a sound strategic decision to
    attempt to lay some of the blame for Boyde’s character on the
    failings of the California Youth Authority, it was probably a
    mistake to employ a quotation from Charles Manson to make
    this point.”
    B
    [18] Because of counsel’s errors, the jury was not presented
    with key evidence that could have inspired sympathy for
    Boyde on account of his childhood. Instead, the jurors heard
    testimony that Boyde had fallen into violence despite a nor-
    mal upbringing, and counsel’s only explanation for this devel-
    opment involved comparing Boyde to Charles Manson. Errors
    of this magnitude are a sufficient basis for finding prejudice.
    Cf. Douglas, 
    316 F.3d at 1090
     (suggesting that counsel’s fail-
    ure to introduce mitigating evidence may be prejudicial if that
    evidence, “[e]ven if . . . not enough to negate an element of
    the underlying offense, . . . could have invoked sympathy
    from at least one member of the jury at the penalty phase”).
    But, the state argues, even if the jury had heard all of the
    available mitigating evidence, the aggravating evidence was
    so overwhelming that the jury would have imposed a death
    sentence anyway. The prosecution presented considerable
    aggravating evidence. Two former classmates of Boyde’s tes-
    tified that he had assaulted them in 1974; another individual
    testified that Boyde had thrown bricks at her van. Boyde’s
    parole agent at CYA testified that Boyde missed meetings and
    stole his stepfather’s gun. Various people testified about
    Boyde’s prior robberies, and a sheriff’s deputy explained that
    Boyde had smoked marijuana in jail while awaiting trial.
    Finally, the prosecution presented evidence that Boyde had
    plotted an escape to avoid trial, and that he had planned to use
    a gun if necessary.
    However, the relevant question for considering the cumula-
    tive prejudicial effect of counsel’s errors is not whether the
    BOYDE v. BROWN                      4525
    sentence would have been different in light of all of this
    aggravating evidence. Much of the evidence presented was
    actually inadmissible, and could have been excluded had
    Boyde’s counsel objected to it. Our prejudice inquiry must
    focus on whether the result would have been different in light
    of the evidence that would have been presented to the jury
    had Boyde’s counsel not been deficient.
    [19] 
    Cal. Pen. Code § 190.3
     provides that “no evidence
    shall be admitted regarding other criminal activity by the
    defendant which did not involve the use or attempted use of
    force or violence or which did not involve the express or
    implied threat to use force or violence.” Boyde’s non-violent
    escape from CYA, as well as his delinquency while there,
    theft of a gun and marijuana use, do not involve violence. In
    fact, the California Supreme Court determined in Boyde’s
    direct appeal that this evidence had been improperly admitted.
    Boyde, 
    758 P.2d at 46
     (“Most of the evidence presented about
    Boyde’s CYA commitment and parole . . . did not pertain to
    a prior felony conviction . . . or criminal activity involving
    force or violence . . . . The same may be said for testimony
    by officers about Boyde’s untruthfulness, possession of stolen
    property and possession of marijuana in jail.”). Because the
    jury in a capital case is asked to evaluate whether aggravating
    circumstances in a defendant’s background outweigh what-
    ever mitigating value it can find, counsel must be especially
    vigilant to ensure that the jury is not presented more aggravat-
    ing facts than the law allows. Boyde’s counsel was deficient
    in failing to object to this harmful evidence, see Crotts, 
    73 F.3d at 866
     (9th Cir. 1996) (“Reasonably competent counsel
    undoubtedly would have objected to the admission of such
    prejudicial evidence.”), which would probably have been
    excluded had he done so.
    This was not the only evidence that should have been
    objected to. The prosecution did not give notice before trial
    that it would introduce evidence of Boyde’s 1974 assault and
    one of his robberies. California law provides that, subject to
    4526                    BOYDE v. BROWN
    limited exceptions inapplicable here, “no evidence may be
    presented by the prosecution in aggravation unless notice of
    the evidence to be introduced has been given to the defendant
    within a reasonable period of time as determined by the court,
    prior to trial.” See 
    Cal. Pen. Code § 190.3
    ; see also Boyde,
    
    758 P.2d at 46
     (recognizing that evidence of these two inci-
    dents “was improperly admitted because the prosecution had
    failed to give proper notice, as required by section 190.3”).
    Again, Boyde’s counsel failed to object. And, again, an objec-
    tion would likely have kept the jury from hearing this evi-
    dence.
    C
    Boyde was prejudiced by his counsel’s multiple errors dur-
    ing the penalty phase if “there is a reasonable probability that,
    but for counsel’s unprofessional errors, the result of the pro-
    ceeding would have been different.” Strickland, 
    466 U.S. at 694
    ; see also Cooper, 
    586 F.2d at 1333
    . In other words, we
    ask whether, absent the errors, there is a reasonable probabil-
    ity that the jury “would have concluded that the balance of
    aggravating and mitigating circumstances did not warrant
    death.” Strickland, 
    466 U.S. at 695
    .
    Because of counsel’s errors, Boyde’s jury was presented
    with a view of his past that omitted his history of physical
    abuse and his family’s history of sexual abuse. Not only was
    it deprived of this evidence that could have engendered sym-
    pathy, Boyde’s counsel all but assured through his summation
    that the jury would not be sympathetic based on the evidence
    he did present. Then, the jury was asked to balance this
    warped view of Boyde’s background against an extensive
    amount of aggravating evidence that it should never have
    heard.
    [20] Of course, we cannot be certain what the jury would
    have done had it been given all of the relevant mitigating
    information and had it not been presented with inadmissible
    BOYDE v. BROWN                       4527
    aggravating evidence. But the fact that the task it actually
    undertook differed so profoundly from the one it would have
    performed had Boyde’s counsel not been deficient is enough
    to undermine our confidence in the sentence it ultimately
    delivered. We find a reasonable probability that the jury
    would have imposed a different sentence but for the errors
    Boyde’s counsel made. See Strickland, 
    466 U.S. at 694
     (“A
    reasonable probability is a probability sufficient to undermine
    confidence in the outcome.”). The district court should have
    granted a conditional writ of habeas corpus as to the penalty
    phase of Boyde’s trial.
    D
    Boyde raises a number of other penalty phase errors,
    including serious due process issues. Because the district
    court should have granted the writ based on Boyde’s ineffec-
    tive assistance claims, we do not reach any of these argu-
    ments.
    *      *     *
    We affirm the district court’s decision to deny Boyde’s
    petition for a writ of habeas corpus because of alleged errors
    in the guilt phase of his trial. We reverse its decision as to the
    penalty phase and remand for the district court to issue a writ
    of habeas corpus, unless within a reasonable time set by the
    district court the state conducts a new penalty phase trial or
    vacates Boyde’s death sentence and imposes a lesser sentence
    consistent with law.
