    SUMMARY *
    Habeas Corpus / Death Penalty
    The panel affirmed the district court’s denial of Steven
    Livaditis’s habeas corpus petition challenging his capital
    sentence.
    Applying Cullen v. Pinholster, 
    563 U.S. 170
    (2011), the
    panel considered only the record before the California
    Supreme Court (including the trial court record), and did not
    consider the evidence presented in the federal court
    evidentiary hearing. Because the California Supreme Court
    summarily denied Livaditis’s state habeas petition, the panel
    considered whether there is any reasonable argument that
    could have supported that decision under the deferential
    AEDPA standard that applies in this context.
    The panel held that the California Supreme Court did not
    unreasonably apply federal law or unreasonably determine
    facts in denying Livaditis’s ineffective assistance of counsel
    claim based on counsel’s failure to investigate and present in
    mitigation evidence of the mental impairments and abusive
    conduct of Livaditis’s mother.           The panel rejected
    Livaditis’s argument that his counsel’s performance was
    constitutionally deficient for failing to discover and present
    this evidence, and concluded that the state court could
    reasonably have concluded that Livaditis was not prejudiced
    by counsel’s failure to do so.

    The panel held that the California Supreme Court could
    have reasonably determined that Livaditis was not
    prejudiced by counsel’s failure to investigate and present in
    mitigation evidence that Livaditis suffered from mental
    impairments prior to and through the time of his crimes. As
    it was unnecessary, the panel did not address counsel’s
    performance with regard to this evidence.

    OPINION
    CLIFTON, Circuit Judge:
    California state prisoner Steven Livaditis appeals the
    district court’s denial of his habeas corpus petition
    challenging his capital sentence. Livaditis pled guilty to
    three counts of first degree murder, five counts of robbery,
    three counts of kidnapping, and one count of second degree
    burglary in connection with his armed robbery of a jewelry
    store in Beverly Hills, California. The California Supreme
    4                    LIVADITIS V. DAVIS
    Court, which had previously affirmed his convictions and
    sentence, denied his habeas petition. The federal district
    court likewise denied his federal petition under 28 U.S.C.
    § 2254. On appeal from that denial, Livaditis argues that the
    district court erred in denying two of his ineffective
    assistance of counsel claims. In particular, he argues that his
    trial counsel was ineffective for failing to investigate and
    present two types of mitigation evidence: 1) evidence that
    Livaditis’s mother was mentally ill and abusive during
    Livaditis’s youth, and 2) evidence that Livaditis suffered
    from mental impairments prior to and through the time of his
    crimes. Under the deferential standard of review that applies,
    we hold that the California Supreme Court could have
    reasonably concluded that both claims lacked merit. We
    therefore affirm.
    I. Background
    On June 23, 1986, twenty-two-year-old Steven Livaditis
    robbed the Van Cleef & Arpels jewelry store in Beverly
    Hills. Shortly after the store opened, Livaditis entered
    carrying a briefcase. A security guard (William Smith) and
    three sales clerks (Ann Heilperin, Hugh Skinner, and Carol
    Lambert) were in the main sales area at the time. Livaditis
    and Heilperin entered the adjoining boutique after Livaditis
    asked to look at some watches. A few minutes later,
    Heilperin screamed. Livaditis, displaying a revolver, forced
    Heilperin back into the main sales area. Although Smith
    attempted to draw his weapon, Livaditis disarmed him. A
    shipping clerk (Robert Taylor) ran into the sales room and
    was also taken hostage. Everyone else in the building
    escaped.
    The police quickly surrounded the store. Livaditis forced
    the five hostages into the watch boutique and ordered Taylor
    LIVADITIS V. DAVIS                      5
    and Lambert to bind the other hostages’ ankles and hands.
    He also ordered them to fill the briefcase with watches.
    Livaditis then attempted to leave the store but returned
    when he saw the police. He ordered Lambert to bind Taylor
    in a sitting position and then dial 911. On the phone,
    Livaditis demanded that he be put on the news and provided
    with a television set and that the police leave. He threatened
    to “execute these people one at a time.”
    Smith was the first hostage to be killed. Livaditis stabbed
    Smith in the back with a hunting knife after Smith said that
    Livaditis thought he was a “big man with that gun.” Smith
    bled to death in front of the other hostages. Livaditis then
    covered Smith’s body, which was still bound and face down
    on the ground, with a coat. He left the knife in Smith’s back.
    Livaditis subsequently told a reporter that he stabbed Smith
    because Smith did not follow orders and “kept talking.”
    Livaditis said that he felt no remorse for the stabbing.
    Heilperin was next. Livaditis appeared angry at
    Heilperin because she screamed at the beginning of the
    robbery. He then ordered her to lie down next to Smith’s
    body. While on the phone with a local media outlet, Livaditis
    told the reporter to wait and then walked over to Heilperin
    and shot her. She died instantly. Livaditis told the reporter
    that his gun had misfired.
    Livaditis held the remaining hostages in the store for
    approximately thirteen hours. Skinner eventually proposed
    an escape plan. Skinner suggested that the three hostages and
    Livaditis exit the store under a blanket so that the police
    would not be able to tell which person was the gunman. They
    would be tied together at the waist, with Livaditis in the
    middle. They would then walk to a nearby car and escape.
    After Livaditis agreed to this plan, Lambert spent a few
    6                    LIVADITIS V. DAVIS
    hours sewing a blanket from cloth used for jewelry displays.
    While she was sewing, Livaditis put more jewelry into his
    briefcase. Once Lambert finished, Livaditis and the hostages
    practiced walking under the blanket for a couple of hours.
    At approximately 11:30 pm, Livaditis and the hostages
    exited the store under the blanket. As they walked, Skinner
    and Taylor yelled that they were hostages. Livaditis
    threatened to kill the hostages if the police intervened. When
    the police threw “flash-bangs” (explosive diversion devices)
    as the group reached the car, the blast separated Skinner
    from Livaditis and the other hostages. Skinner pointed to
    Livaditis and yelled, “Here he is.” Unfortunately, a police
    sharpshooter stationed on a nearby parking structure
    mistakenly believed that both male hostages were black and
    that only Livaditis was white. In fact, Skinner was also
    white. When the sharpshooter saw Skinner, a white man who
    resembled the general description the police had received of
    the gunman, he believed that Skinner was the perpetrator.
    The sharpshooter heard his spotter say “shiny object” and
    heard someone else say “gun.” He then shot and killed
    Skinner, believing that Skinner was the gunman and was
    about to start killing one or more of the remaining hostages.
    At that point, the officers arrested Livaditis. Livaditis
    told the police that he killed Smith because Smith had been
    “uncooperative and antagonistic” and “to keep control of the
    situation.” He said that he killed Heilperin because “he felt
    that he had to kill another hostage in order to prove that his
    demands should be taken seriously.” He said that he was
    sorry and that his plan had only been to rob the store.
    Livaditis pled guilty to the first degree murders of Smith,
    Heilperin, and Skinner; five counts of robbery; three counts
    of kidnapping; and one count of second degree burglary. He
    admitted several special circumstance allegations, including
    LIVADITIS V. DAVIS                       7
    murder during the commission of robbery and burglary,
    multiple murder, and weapons enhancements. After jury
    selection, the case proceeded to the penalty phase.
    A. The Penalty Phase
    During the penalty phase, in addition to evidence about
    the circumstances of the Van Cleef & Arpels robbery and
    murders, the state presented evidence of prior crimes and bad
    acts by Livaditis. That included evidence that he robbed a
    jewelry store in Las Vegas at gunpoint in February 1986,
    four months before the Beverly Hills crimes. During the Las
    Vegas robbery, Livaditis forced two store employees to lie
    bound on the floor, threatened to kill them, and kicked one
    of them repeatedly. He escaped with jewelry worth over
    $400,000 retail, or $177,555 wholesale. Livaditis also had
    one prior felony conviction for burglary and one for
    possession of stolen property. In addition, the state’s
    evidence described three prior instances in which Livaditis
    forcibly resisted arrest.
    In arguing for a sentence less than death, the defense
    focused on several mitigation themes, including family
    sympathy, pleas for mercy, and Livaditis’s acceptance of
    responsibility for his crimes. Seven witnesses testified on
    Livaditis’s behalf.
    Sophie Livaditis, Livaditis’s mother, explained the
    circumstances of her arrival to the United States and
    described her tumultuous marriage to Louis Livaditis,
    Livaditis’s father. She testified that Louis abused her in front
    of their children and abused their children as well. She
    explained that due to her recurring illnesses, she had to send
    Livaditis to St. Basil’s Academy, a Greek Orthodox
    orphanage in upstate New York, for two years during his
    childhood. According to Sophie, Livaditis was “never happy
    8                   LIVADITIS V. DAVIS
    there” because he was homesick. She also described the
    severe appendicitis Livaditis suffered as a child and a head
    injury that he received at St. Basil’s. She said that she “had
    no problems” with her children and was “very close” with
    Livaditis.
    Sophie believed that Livaditis’s problems began during
    his time in the U.S. Army and became worse after he left the
    service and moved to Las Vegas. She said that the move was
    “his disaster” because “he enrolled himself with the bad
    people.” She said that she was shocked when she found out
    about his crimes because the family “never had problems”
    and Livaditis had “good plans for the future.” She said that
    her son “knows that he did a very bad thing” and that she
    “was hurt, very ashamed” and was “grieving with the
    victims’ family.”
    On cross-examination, Sophie testified that her ex-
    husband hit and spanked each of her children and repeatedly
    stated that all of her children had the same upbringing and
    the same advantages and disadvantages. She reaffirmed that
    she never had trouble with her children.
    Two of Livaditis’s aunts and one of his uncles also
    testified on his behalf. Their statements were generally
    similar to Sophie’s testimony. One aunt, Pauline Poulakos,
    testified that Louis Livaditis was “like a monster in the
    house” and that the children were afraid of him. She said that
    Louis hit Sophie, including while she was pregnant. She
    described Livaditis’s unhappiness at St. Basil’s and his
    desire to return home. She said that Livaditis was a “normal
    boy” who tried to help his mother and that he was “very, very
    sorry” for what he did. She also rooted his problems in his
    move to Las Vegas.
    LIVADITIS V. DAVIS                      9
    Voula Boulari, the other aunt, testified about Livaditis’s
    “delicate character” as a child. She said that she would not
    imagine that he would commit such a crime and that she was
    “ashamed of what he did.” She said that he “has completely
    regretted what he did” and that he told her that he “went there
    just to steal and not cause any other trouble and then he was
    afraid.”
    Theofanis Thantzalos, Livaditis’s uncle, testified about
    Livaditis’s time at St. Basil’s. He also said that Livaditis
    “acted natural” when he lived with them in Greece as a
    teenager. Like Sophie, Theofanis indicated that Livaditis’s
    problems dated back to his time in the army. He recalled that
    when Livaditis visited Greece on a leave of absence from the
    army, “he acted kind of wild.”
    Father Angelo Gavalas, the family’s Greek Orthodox
    priest, testified about Sophie’s challenges as a severely ill
    single parent. He said that Livaditis had an excellent
    relationship with Sophie. He also discussed Livaditis’s time
    at St. Basil’s and said that Livaditis “managed to stay two
    years under great duress” because he was very unhappy
    there. Father Gavalas testified that the Livaditis family was
    “close knit,” so that “if something happens to one of them, it
    really happens to all of them.”
    Livaditis’s brother, George, testified next. He said that
    he had “sort of blacked out” his younger years but that he
    remembered that his parents’ relationship “wasn’t too nice.”
    He said that life after his parents divorced was “kind of
    tough” because his mother had to take care of four children
    alone and struggled to make ends meet, to the point that she
    was forced to sort through garbage cans to find food and
    clothes. George said that Livaditis “was always the first to
    try and do something” to help their mother. He also indicated
    that Livaditis’s problems originated in Las Vegas. He
    10                   LIVADITIS V. DAVIS
    believed that when Livaditis moved to Las Vegas, he was
    “more confused than ever before” and “really didn’t know
    why he was born, basically, his purpose in life.” On cross-
    examination, George testified that Livaditis was Sophie’s
    favorite but said that Livaditis was not treated differently
    than the other children, with the exception of traveling to
    Greece with Sophie.
    Finally, Livaditis’s sister Fanny testified. She said that
    Livaditis was very close to Sophie and spent more time with
    her than the other children. Fanny testified that Livaditis
    “wasn’t very talkative” and “looked very preoccupied and
    sort of moody and depressed” after he left the military.
    Livaditis told her that he felt confused and couldn’t find any
    meaning in his life. Fanny said that she forgave Livaditis for
    what he did and wanted him to live. Livaditis’s other sister
    did not testify.
    In closing arguments, the state argued that Livaditis’s
    prior crimes were the beginning of a pattern of criminality
    that his family either did not see or did not want to see. The
    state argued that all of the Livaditis children “basically had
    the same background,” but “if anyone had more of an
    advantage growing up than anyone else, it would be the
    defendant” because he was “obviously the favorite of the
    mother.” The state emphasized that Livaditis “had good
    family” and “a good support network” but engaged in a
    pattern of refusing to take responsibility for his bad choices.
    The state then detailed the circumstances of the Van Cleef &
    Arpels robbery and the murders of the three hostages and
    placed particular emphasis on the fact that Livaditis made
    the choice to commit these crimes and bore full
    responsibility for the consequences.
    During the defense’s closing argument, Livaditis’s
    attorney, Michael Demby, noted that Livaditis had accepted
    LIVADITIS V. DAVIS                     11
    responsibility for his crimes and admitted his guilt, even
    though he knew that he would either get life in prison
    without parole or the death penalty. He urged the jury to be
    cautious in deciding on the death penalty and asked them to
    look at Livaditis’s background. He said that Livaditis did not
    have a lifetime record of criminality, unlike many other
    defendants, and had not been planning to kill the hostages.
    Demby repeatedly emphasized the effect of Livaditis’s
    crimes and sentence on his family members, who knew a
    “good” and “kind” side of Livaditis.
    The jury began its deliberations on June 16 and returned
    a verdict of death on June 19, 1987. Livaditis was sentenced
    to death on July 8, 1987.
    B. Procedural History
    The California Supreme Court affirmed Livaditis’s death
    sentence, without dissent, in a published opinion filed on
    June 18, 1992. People v. Livaditis, 
    831 P.2d 297
    (Cal. 1992).
    The United States Supreme Court denied his petition for a
    writ of certiorari on March 8, 1993. Livaditis v. California,
    
    507 U.S. 975
    (1993) (mem.).
    Livaditis successfully applied for a stay of execution and
    appointment of counsel from the federal district court on
    April 22, 1996. He filed his first federal habeas petition on
    April 23, 1997. On August 20, 1997, he simultaneously filed
    a habeas petition in the California Supreme Court and an
    amended federal habeas petition in the district court. The
    California Supreme Court summarily denied his state
    petition for a writ of habeas corpus on the merits on
    November 24, 1998.
    The district court granted Livaditis leave to file a second
    amended habeas petition on August 12, 1999. After
    12                      LIVADITIS V. DAVIS
    substantial briefing and other litigation activity, the district
    court, considering only the record before the California
    Supreme Court, denied Livaditis’s habeas petition in a
    lengthy written order filed on July 8, 2014. 1
    Livaditis appealed. He requested a certificate of
    appealability on three claims. A motions panel of our court
    granted a certificate of appealability on part of his claim that
    he received ineffective assistance of counsel (“Claim 11”),
    namely, whether “trial counsel was effective at the penalty
    phase in failing to present any mitigating evidence
    concerning: (i) Petitioner’s alleged mental health problems;
    and (ii) Petitioner’s allegedly abusive and mentally unstable
    mother.” Livaditis does not present any uncertified claims
    on appeal.
    II. Discussion
    We review the district court’s denial of habeas relief de
    novo. Hurles v. Ryan, 
    752 F.3d 768
    , 777 (9th Cir. 2014).
    Because Livaditis filed his petition after April 24, 1996, the
    Antiterrorism and Effective Death Penalty Act (AEDPA)
    governs our review of his habeas claims. Under AEDPA, we
    may grant a writ of habeas corpus only if the state court’s
    1
    The district court had earlier issued an order granting an
    evidentiary hearing on various claims in the petition, including the
    claims that Livaditis raises on appeal. The evidentiary hearing took place
    over four days in 2010. After the evidentiary hearing, the Supreme Court
    issued its decision in Cullen v. Pinholster, 
    563 U.S. 170
    (2011). In
    Pinholster, the Court held that a federal habeas court conducting review
    under AEDPA “is limited to the record that was before the state court
    that adjudicated the claim on the merits.” 
    Id. at 181.
    The parties filed
    briefs with the district court addressing the impact of the decision on
    Livaditis’s petition. The district court ultimately considered only the
    record before the California Supreme Court in denying Livaditis’s
    habeas petition.
    LIVADITIS V. DAVIS                       13
    adjudication of the merits 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.” 28 U.S.C. § 2254(d).
    This is a high bar, as “it was meant to be.” Harrington v.
    Richter, 
    562 U.S. 86
    , 102 (2011). “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. at 101
    (quotation marks omitted).
    Where, as here, a state court summarily denies a claim, a
    petitioner “can satisfy the ‘unreasonable application’ prong
    of § 2254(d)(1) only by showing that ‘there was no
    reasonable basis’ for the [state court’s] decision.” Cullen v.
    Pinholster, 
    563 U.S. 170
    , 188 (2011) (quoting 
    Richter, 562 U.S. at 98
    ). We “must determine what arguments or
    theories . . . could have supporte[d] the state court’s
    decision; and then [we] must ask whether it is possible
    fairminded jurists could disagree that those arguments or
    theories are inconsistent with the holding in a prior decision
    of [the Supreme Court].” 
    Id. at 188
    (some alterations in
    original) (quoting 
    Richter, 562 U.S. at 102
    ). Our review is
    “limited to the record that was before the state court that
    adjudicated the claim on the merits.” 
    Id. at 181.
    We evaluate a habeas claim de novo and consider
    evidence presented for the first time in federal court only if
    we find, “considering only the evidence before the state
    court, that the adjudication of a claim on the merits resulted
    in a decision contrary to or involving an unreasonable
    application of clearly established federal law, or that the state
    14                       LIVADITIS V. DAVIS
    court’s decision was based on an unreasonable
    determination of the facts.” 
    Hurles, 752 F.3d at 778
    .
    A. The Record on Appeal
    In Pinholster, a habeas case involving another California
    murder conviction and capital sentence, the Supreme Court
    held that a federal habeas court conducting review under
    AEDPA “is limited to the record that was before the state
    court that adjudicated the claim on the 
    merits.” 563 U.S. at 181
    . This rule applies even when the state court has
    summarily denied the habeas claims. See 
    id. at 181,
    188.
    The district court correctly applied Pinholster. It based
    its decision only on the record before the California Supreme
    Court (including the trial court record 2) and did not consider
    the evidence presented in the federal court evidentiary
    hearing. We take the same approach.
    B. Ineffective Assistance of Counsel Claims
    Livaditis raises two ineffective assistance of counsel
    claims on appeal. He argues that his trial counsel was
    deficient for failing to present two categories of mitigating
    2
    In Pinholster, the Supreme Court also explained that when the
    California Supreme Court issues a summary denial of a habeas claim, it
    “generally assumes the allegations in the petition to be true, but does not
    accept wholly conclusory allegations, and will also ‘review the record of
    the trial to assess the merits of the petitioner’s 
    claims.’” 563 U.S. at 188
    n.12 (alterations and citation omitted) (quoting In re Clark, 
    855 P.2d 729
    ,
    742 (Cal. 1993)).
    The record before the California Supreme Court in this case
    included both the allegations in Livaditis’s habeas petition and the record
    of the trial. See 
    id. The California
    Supreme Court had previously
    reviewed the trial record in connection with Livaditis’s direct appeal.
    LIVADITIS V. DAVIS                   15
    evidence: 1) additional information about Sophie Livaditis’s
    abuse and mental illness; and 2) information about
    Livaditis’s mental illness and brain damage.
    For our review under AEDPA of claims of ineffective
    assistance of counsel, the law clearly established by
    decisions of the U.S. Supreme Court is Strickland v.
    Washington, 
    466 U.S. 668
    (1984). See Ayala v. Chappell,
    
    829 F.3d 1081
    , 1096 (9th Cir. 2016). Under Strickland, the
    petitioner must satisfy a two-part test:
    First, the [petitioner] must show that
    counsel’s performance was deficient. This
    requires showing that counsel made errors so
    serious that counsel was not functioning as
    the “counsel” guaranteed the defendant by
    the Sixth Amendment. Second, the
    [petitioner] must show that the deficient
    performance prejudiced the defense. This
    requires showing that counsel’s errors were
    so serious as to deprive the [petitioner] of a
    fair trial, a trial whose result is 
    reliable. 466 U.S. at 687
    .
    Our review “of counsel’s performance must be highly
    deferential.” 
    Id. at 689.
    We must “indulge a strong
    presumption that counsel’s conduct falls within the wide
    range of reasonable professional assistance.” 
    Id. When reviewing
    a state court’s decision on a Strickland claim
    under AEDPA, the federal court’s review must be “doubly”
    deferential, 
    Richter, 562 U.S. at 105
    , because Strickland
    provides courts with a general standard:
    Because judicial application of a general
    standard “can demand a substantial element
    16                   LIVADITIS V. DAVIS
    of judgment,” the more general the rule
    provided by the Supreme Court, the more
    latitude the state courts have in reaching
    reasonable outcomes in case-by-case
    determinations. Yarborough v. Alvarado,
    
    541 U.S. 652
    , 664 (2004). In turn, the state
    courts’ greater leeway in reasonably applying
    a general rule translates to a narrower range
    of decisions that are objectively unreasonable
    under AEDPA. Accordingly, we review a
    state court’s decision applying Strickland’s
    general principles with increased, or double,
    deference.
    Cheney v. Washington, 
    614 F.3d 987
    , 995 (9th Cir. 2010).
    The California Supreme Court denied Livaditis’s
    petition summarily. Because it did not discuss its reasons for
    denying the claims of ineffective assistance of counsel, the
    question before us becomes “whether there is any reasonable
    argument” that could have supported that decision under the
    deferential standard that applies in this context. 
    Richter, 562 U.S. at 105
    .
    After considering the record, we conclude that there
    were reasonable grounds to support the denial of relief by
    the California Supreme Court on Livaditis’s claims of
    ineffective assistance of counsel. Put in terms of the relevant
    standard under AEDPA, the decision by the California
    Supreme Court was not based on an unreasonable
    application of the law or determination of facts.
    1. The Defense Strategy
    Michael Demby, a deputy public defender, was
    appointed to represent Livaditis shortly after his arrest. At
    LIVADITIS V. DAVIS                    17
    that point, Demby had more than seventeen years of
    experience as a public defender. An investigator assisted
    Demby on the case.
    Demby provided a declaration in Livaditis’s state habeas
    proceedings explaining his strategy for the penalty phase. In
    this declaration, Demby stated that he “knew early on that a
    penalty phase investigation was of primary importance in
    preparing for trial.” Demby stated that Livaditis cooperated
    with preparations for trial and that he interviewed Livaditis
    about his background multiple times. Demby also
    interviewed several of Livaditis’s family members.
    According to Demby, these interviews made it “obvious that
    Mr. Livaditis came from a very dysfunctional family.” In
    particular, he “knew from other members of the family that
    [Livaditis’s mother] suffered from mental and physical
    illnesses throughout Mr. Livaditis’s childhood.” According
    to Demby, Livaditis’s mother initially refused to cooperate
    meaningfully in Livaditis’s defense. Demby also knew that
    Livaditis’s sister, Pauline, was mentally ill.
    Demby learned that Livaditis “had serious abandonment
    issues” and that his father had been abusive. Livaditis was
    placed at St. Basil’s when he was eight and stayed there for
    almost two years, even though he was extremely unhappy.
    The family only removed him when he began to starve
    himself and became very ill. Demby learned that Livaditis
    was then “shuffled to different family members, including
    an aunt and uncle in Greece who physically and
    psychologically abused him.” He also discovered that
    Livaditis had other physical problems in his youth, including
    at least two head injuries, nearly fatal appendicitis, and a
    serious fall.
    18                      LIVADITIS V. DAVIS
    Demby stated that did not obtain or review additional
    records in preparing Livaditis’s defense because the trial
    commenced before he was fully prepared:
    The trial prematurely ended my efforts to
    obtain medical records and other social
    history documents, and it prevented any
    attempts to obtain more information about
    the orphanage where Mr. Livaditis was so
    unhappy as a child as well as information
    regarding Mr. Livaditis’s training and service
    in the Army Reserves. Had I been given
    additional time, I would have done
    everything I could to obtain additional
    medical records and related social history
    documents. 3
    Demby stated that his initial strategy was to focus on the
    physical abuse that Livaditis’s father and uncle inflicted on
    him, as well as the detrimental effect of his family’s
    abandonment. Ultimately, however, Demby decided to
    present testimony from Livaditis’s family members instead.
    He hoped that “the jury would like these family members
    and would want to do something for them, even if they did
    not want to do something for Mr. Livaditis.” He based this
    decision on interviews that he conducted with various
    members of the family in Greece, including Sophie
    Livaditis.
    To that end, Demby’s mitigation strategy focused on the
    closeness of the family and the fact that Livaditis only began
    3
    There is no claim before us that Livaditis’s trial counsel did not
    have adequate time to prepare for the penalty phase of trial, or that the
    trial court wrongly denied a motion to continue the trial.
    LIVADITIS V. DAVIS                    19
    to have problems as a young adult after leaving the army.
    Demby also elicited testimony that Livaditis’s father was
    abusive, but he did not probe into the abuse in depth.
    2. Mental Illness of and Abuse by Livaditis’s Mother
    Livaditis argues that Demby’s assistance was
    constitutionally deficient because Demby was aware that
    Livaditis’s mother, Sophie, suffered from severe mental
    illness and had abused her children but failed to investigate
    further or present any of this evidence in mitigation. The
    information that Demby was aware of included statements
    of family members and the family priest describing Sophie
    as depressed, ill, emotionally and mentally unstable, and in
    need of special therapy; a statement from a family member
    that Sophie abused Livaditis; and statements from family
    members and Livaditis describing his misery at St. Basil’s
    and the rarity of Sophie’s visits.
    Based on this information, Livaditis now contends that
    Demby should have pursued further investigation into
    Sophie’s background and abuse. He argues that, had Demby
    and his investigator performed proper interviews with family
    members, they would have learned that Sophie and her
    family experienced hardship in Greece; mental illness was
    common in Sophie’s family; Sophie’s parents were mentally
    ill; Sophie was “essentially sold” to relatives in the United
    States who did not treat her well; Sophie’s marriage to Louis
    Livaditis was difficult from the beginning; Sophie attempted
    to self-induce abortions, including while pregnant with
    Livaditis, because she did not want children; Sophie beat all
    of her children; relatives described her as suffering from a
    nervous breakdown and odd behavior after she and Louis
    were divorced; Sophie prohibited her children from
    contacting any member of the Livaditis family, including
    Louis; she was referred for a psychiatric consultation
    20                  LIVADITIS V. DAVIS
    because of “bizarre behavior” during a hospital stay,
    resulting in a diagnosis of a “hysterical personality with the
    possibility of underlying ego pathology,” with a possible
    dissociative disorder; and Sophie enlisted other relatives to
    discipline and beat her children. Livaditis argues that
    Demby’s performance as his attorney was constitutionally
    deficient for failing to discover and present any of this
    evidence in mitigation.
    We disagree. Under Strickland, “strategic choices made
    after less than complete investigation are reasonable
    precisely to the extent that reasonable professional judgment
    supports the limitations on investigation. In other words,
    counsel has a duty to make reasonable investigations or to
    make a reasonable decision that makes particular
    investigations 
    unnecessary.” 466 U.S. at 690
    –91. Reviewing
    courts must “apply[] a heavy measure of deference to
    counsel’s judgments” about the decision not to investigate.
    
    Id. at 691.
    The record reflects that Demby did perform an initial
    investigation of Livaditis’s social background, including his
    mother’s abuse and mental illness. Although Demby
    apparently did not have all of the information that Livaditis
    describes, he was aware that a focus on Sophie’s abuse and
    mental illness was a possible mitigation strategy. Once he
    became aware of an alternative strategy, namely, mercy
    based on pleas from Sophie and other sympathetic family
    members, he was in a position to make a reasonable decision
    about how to proceed, and whether to continue to investigate
    Sophie’s background.
    The additional evidence of Sophie’s mental illness and
    abuse that Demby failed to discover did not differ
    meaningfully from the evidence that Demby already had.
    Rather, it primarily added details about issues of which
    LIVADITIS V. DAVIS                    21
    Demby was already aware. The California Supreme Court
    could have reasonably concluded that this additional
    evidence would not have altered Demby’s strategy. See
    Bobby v. Van Hook, 
    558 U.S. 4
    , 11–12 (2009) (“[This] is . . .
    a case, like Strickland itself, in which defense counsel’s
    ‘decision not to seek more’ mitigating evidence from the
    defendant’s background ‘than was already in hand’ fell ‘well
    within the range of professionally reasonable judgments.’”
    (quoting 
    Strickland, 466 U.S. at 699
    )).
    Likewise, the California Supreme Court could
    reasonably have concluded that Demby did not select a
    constitutionally deficient mitigation strategy. The U.S.
    Supreme Court has recognized that a “mercy” or “family
    sympathy” theme is a valid approach to mitigation. See
    
    Pinholster, 563 U.S. at 191
    (denying petitioner’s ineffective
    assistance of counsel claim, in part because the “family
    sympathy” mitigation strategy “was known to the defense
    bar in California [in 1984] and had been used by other
    attorneys”). And here, pleading for mercy on behalf of
    Livaditis’s family was a legitimate strategy given its
    closeness, which Demby understood after extensive
    interviews with the family.
    Furthermore, as the district court correctly noted,
    emphasizing Sophie’s abuse of Livaditis would have been
    inconsistent with portraying her as a sympathetic witness
    and would therefore have limited the efficacy of a family
    sympathy approach. Indeed, in light of the challenges that
    Demby had in convincing Sophie to cooperate with his
    investigation and testify during the sentencing, portraying
    Sophie as severely mentally ill could have had a detrimental
    impact on her participation in the trial. In addition, this
    evidence could have undercut the jury’s view of her
    testimony.
    22                  LIVADITIS V. DAVIS
    As for the second prong under Strickland, the state court
    could also reasonably have concluded that Livaditis was not
    prejudiced by Demby’s failure to present evidence of
    Sophie’s mental illness and abuse. Demby did elicit some
    testimony about Livaditis’s difficult upbringing during the
    penalty phase. Although evidence of Sophie’s abuse would
    have added to this testimony, much of the new evidence that
    Livaditis cites was cumulative. The California Supreme
    Court could reasonably have concluded that this evidence
    would not have changed the outcome of Livaditis’s
    sentencing. See Wong v. Belmontes, 
    558 U.S. 15
    , 22–23
    (2009) (holding that the state court could reasonably have
    concluded that the petitioner was not prejudiced when the
    evidence that counsel failed to present was cumulative of the
    “humanizing” evidence counsel used because the jury was
    already “‘well acquainted’ with [the petitioner’s]
    background and potential humanizing features” (quoting
    Schriro v. Landrigan, 
    550 U.S. 465
    , 481 (2007))).
    We conclude that the California Supreme Court did not
    unreasonably apply federal law or unreasonably determine
    facts in denying the ineffective assistance of counsel claim
    based on the mental impairments and abusive conduct of
    Livaditis’s mother.
    3. Livaditis’s Mental Impairments
    Livaditis also argues that Demby was constitutionally
    deficient because he was aware that Livaditis had signs of
    possible mental illness but failed to investigate further or
    present any of this evidence in mitigation.
    Livaditis correctly asserts Demby had information
    suggesting that Livaditis may have been mentally ill. That
    information included Livaditis’s own statements to Demby
    that he was a little “unstable,” had not been “thinking like a
    LIVADITIS V. DAVIS                     23
    normal person,” and was “screwed up in the head”;
    Livaditis’s statements to Demby that at the beginning of the
    robbery, he was “high” and “excited” and felt “like he was
    President of the United States,” but later he felt angry and
    likened his feelings to a person who was at “a party having
    a good time and somebody does something to ruin it”; a co-
    worker’s statement that Livaditis was “a hyper person who
    was given to abrupt mood swings”; a statement from
    Livaditis to his cousin that he experienced “an inner rage that
    left him confused”; a copy of the police hostage negotiator’s
    notes that described Livaditis’s false assertions that he was a
    Vietnam veteran, a college graduate with several degrees,
    was fluent in four languages, was capable of “maxing”
    aptitude tests, and was able to move water with telekinesis;
    a transcript of Livaditis’s post-arrest interview indicating
    that he was chuckling to himself and said that he killed one
    of the hostages because something “kicked inside” and he
    heard a voice telling him to kill the hostage; and an interview
    with the media in which Livaditis described himself as a
    Robin Hood figure. Demby also received Livaditis’s school
    records, which indicated that Livaditis was a “below average
    student” who had an “inability to read with comprehension”
    and was recommended to repeat third grade; and the
    transcript of a police interview in which Livaditis said that
    he may not be able to keep up with their interview questions
    because he did not have a lot of “understanding.”
    Demby’s trial notes indicate that he discussed the issue
    of mental illness with Livaditis. Those notes reflect that
    Livaditis told Demby that he was “not crazy,” although it
    had “crossed his mind to act crazy” and he could “do a good
    job” acting the part. The notes indicate that Livaditis
    considered feigning mental illness because he had “heard
    they could not execute an insane person.” Demby also
    24                  LIVADITIS V. DAVIS
    consulted a “mental health expert,” although the record is
    silent regarding the results of that consultation.
    Livaditis argues that Demby should have investigated
    Livaditis’s mental impairments further. Had he done so,
    Livaditis contends that he could have discovered jail medical
    records requesting toxicology testing, which a doctor
    ordered after he observed “Abnormal Behavior,” with a
    handwritten notation of “Drugs/vs/Psychosis”; the results of
    that toxicology testing that showed no presence of drugs or
    alcohol; jail records from a few days after Livaditis’s arrest
    indicating that he told staff that he was “hearing voices” and
    was “willing to see psych”; and a psychiatrist’s tentative
    assessment that he had an “adjustment disorder” with
    “mixed emotional features” and an antisocial personality
    disorder.
    In the state post-conviction proceedings, Livaditis’s
    new counsel retained three mental health experts to perform
    an analysis of Livaditis’s mental health. Dr. Rosenberg, a
    psychologist, prepared a report after interviewing Livaditis
    for 18 ½ hours, Fanny Livaditis for 5 hours, and George
    Livaditis for 5 hours. She also used a detailed social history
    of Livaditis and related exhibits to prepare her evaluation.
    She concluded that Livaditis’s childhood trauma “adversely
    affected his subsequent psychological development,
    including his behavioral, social, emotional, and cognitive
    functioning.”
    Dr. Watson, a neuropsychologist, performed an
    evaluation based on 17 hours of interviews and tests. Dr.
    Watson also reviewed family declarations, Livaditis’s
    hospital records from 1985 and 1986, his educational and
    army records, other family medical records, his jail medical
    records, and Dr. Rosenberg’s declaration. Dr. Watson
    concluded that Livaditis had a “mild degree of
    LIVADITIS V. DAVIS                          25
    neuropsychological    impairment”     and     intellectual
    functioning “below that expected based upon both
    demographic and performance characteristics.”
    Dr. Foster, a neuropsychiatrist, provided an expert
    declaration on the basis of four sets of examinations,
    interviews, and tests that he conducted over 16 hours. He
    also reviewed Dr. Rosenberg’s social history, the
    declarations of family members and acquaintances, and Dr.
    Watson’s report. Dr. Foster found that Livaditis suffered
    from “severe psychiatric disorders, neuropsychological and
    medical deficits which significantly compromised his ability
    accurately to perceive and understand the world around him,
    his ability to respond adequately to complex situations, and
    his ability to function normally.” According to Dr. Foster,
    Livaditis’s disorders included both post-traumatic stress
    disorder and a “severe mood disorder with intermittent
    psychotic features,” most likely bipolar disorder, but
    possibly schizoaffective disorder. Dr. Foster also concluded
    that Livaditis’s symptoms were “consistent with acquired
    and, perhaps, congenital brain injury.”
    After reviewing that record, the district court held that
    the California Supreme Court could have reasonably denied
    Livaditis’s habeas petition under both prongs of Strickland.
    With respect to prejudice, we agree. We conclude that the
    California Supreme Court could have reasonably determined
    that Livaditis was not prejudiced at the penalty phase. 4
    “Establishing prejudice in the death sentence context
    requires a showing that there is a reasonable probability that,
    absent the errors, the sentencer would have concluded that
    4
    As it is unnecessary, we do not address Demby’s performance. See
    
    Pinholster, 563 U.S. at 202
    .
    26                  LIVADITIS V. DAVIS
    the balance of aggravating and mitigating circumstances did
    not warrant death. The defendant bears the highly
    demanding and heavy burden of establishing actual
    prejudice.” Bible v. Ryan, 
    571 F.3d 860
    , 870 (9th Cir. 2009)
    (quotations and punctuation omitted). For three reasons, we
    conclude that the California Supreme Court could have
    reasonably determined that Livaditis did not meet that
    burden.
    First, several aggravating circumstances supported the
    jury’s verdict. This was not the first time that Livaditis had
    demonstrated ruthlessness during the commission of a
    violent crime. As noted above, the state presented evidence
    of Livaditis’s record of crimes and bad acts. In particular,
    four months before the Beverly Hills robbery and murders,
    Livaditis robbed a jewelry store in Las Vegas at gunpoint.
    During that robbery, he tied up two of the store’s employees,
    verbally abused them, threatened to kill them, and kicked
    one of the bound employees repeatedly.
    Livaditis exhibited similar callousness during the
    Beverly Hills robbery and murders when he killed Smith and
    Heilperin. He stabbed Smith because Smith verbally defied
    him and let him bleed to death in front of the other hostages.
    He then killed Heilperin because he wanted to prove that his
    demands were serious. He chose Heilperin because she had
    screamed at the start of the robbery. As in the Las Vegas
    robbery, both victims were helpless. Moreover, during press
    interviews Livaditis indicated that he believed Smith’s
    stabbing was “appropriate.” The cruelty Livaditis displayed
    over the course of multiple crimes constituted a substantial
    aggravating factor. See, e.g., Sully v. Ayers, 
    725 F.3d 1057
    ,
    1069 (9th Cir. 2013) (“staggering” aggravating evidence
    weighed against a conclusion that defendant was
    prejudiced); 
    Bible, 571 F.3d at 870
    (the “powerful
    LIVADITIS V. DAVIS                    27
    aggravating circumstances surrounding [the] murder”
    weighed against a conclusion that defendant was
    prejudiced).
    Second, the California Supreme Court could have
    reasonably decided to accord the declarations submitted by
    Livaditis’s mental health experts little weight.         Dr.
    Rosenberg focused on describing the psychological effects
    of Livaditis’s abusive childhood. Because Demby elicited
    testimony that demonstrated that Livaditis had been abused
    as a child and the jury could have inferred negative effects
    from that treatment, the California Supreme Court could
    have considered Dr. Rosenberg’s testimony cumulative. See
    
    Wong, 558 U.S. at 22
    –23. Moreover, Dr. Rosenberg did not
    propose a clinical diagnosis. See Runningeagle v. Ryan, 
    825 F.3d 970
    , 987 (9th Cir. 2016) (discounting mental health
    declaration that “gave no affirmative diagnosis”).
    Dr. Watson indicated only that Livaditis suffered from a
    “mild degree of neuropsychological impairment.” The
    California Supreme Court could have concluded that
    mitigating effect of that statement was limited. See 
    id. at 987–88
    (giving limited weight to mental health diagnosis
    that “used qualifying language”).
    Dr. Foster discussed Livaditis’s history of trauma, child
    abuse, and neglect. Although Dr. Foster proposed several
    clinical diagnoses, those diagnoses were based on interviews
    conducted nearly ten years after the murders. See 
    id. at 988
    (discounting diagnosis produced more than 20 years after the
    crimes were committed). Moreover, on the crucial issue of
    brain damage, Dr. Foster simply opined that Livaditis’s
    symptoms were “consistent with” brain damage. See Leavitt
    v. Arave, 
    646 F.3d 605
    , 614 (9th Cir. 2011) (holding, in pre-
    AEDPA case, that mental health opinions that “couch results
    28                  LIVADITIS V. DAVIS
    in tentative language” are “simply not enough to show
    prejudice”).
    The record also reflected that Livaditis had told Demby
    that he was “not crazy” but that he had considered acting
    crazy and could “do a good job” at that. The California court
    may have decided as a result to treat with skepticism expert
    statements based on interviews of Livaditis conducted years
    after he had already been sentenced to death. That skepticism
    could have been fueled by Demby’s own declaration, which
    indicated that he had consulted his own mental health expert
    at trial. It would not have been unreasonable for the
    California Supreme Court to discount the testimony of these
    mental health experts.
    Third, as discussed above, Demby put on extensive
    mitigation evidence, including testimony from Livaditis’s
    family. One of the key themes of Demby’s mitigation
    strategy was the closeness of the family and the jurors’
    potential sympathy for Livaditis’s mother, Sophie. The
    mental health experts’ declarations discussed the abuse
    Livaditis suffered at Sophie’s hands at length. All three
    experts relied on that abuse in reaching their conclusions.
    Any testimony along the lines suggested by the later
    testimony from those experts would almost certainly have
    touched on Sophie’s abuse. That testimony could have
    rendered Sophie far less sympathetic in the jurors’ eyes.
    Thus, if Demby had called on mental health experts during
    mitigation, those experts may have undercut the mitigation
    case that Demby did put on. Cf. 
    Pinholster, 563 U.S. at 202
    (no prejudice where, inter alia, “some of the new testimony
    would likely have undercut the mitigating value of the
    testimony by Pinholster’s mother”).
    After considering the aggravating evidence adduced, the

    the mitigation evidence he could have presented, the
    California Supreme Court could have reasonably concluded
    that further evidence concerning Livaditis’s mental health
    would not have made a difference. More precisely, in the
    terms used in Strickland, the California Supreme Court
    could have reasonably concluded that there was not a
    “reasonable probability that . . . the result of the proceeding
    would have been different.”

    III.     Conclusion
    We affirm the district court’s denial of Livaditis’s
    petition for a writ of habeas corpus. Under de novo review,
    we might reach a different conclusion. Especially under the
    double deference that applies to our review, however, we
    cannot say that the inferred conclusions by the California
    Supreme Court constituted unreasonable applications of
    federal law or unreasonable determinations of the facts. See
