    ________________________
    Appeal from the United States District Court
    for the Southern District of Florida
    ________________________
    (October 12, 2016)
    Before HULL, MARCUS and JILL PRYOR, Circuit Judges.
    PER CURIAM:
    In this capital case, Guillermo Arbelaez appeals the district court’s denial of
    his federal habeas petition. Arbelaez was sentenced to death in Florida for the
    Case: 14-14647      Date Filed: 10/12/2016      Page: 2 of 27
    murder of his former girlfriend’s five year old son, which he carried out to exact
    revenge against her after an argument. Following an unsuccessful direct appeal
    and collateral proceedings in the Florida state courts, Arbelaez filed a federal
    habeas petition in the United States District Court for the Southern District of
    Florida, which the district court denied. Arbelaez appeals the rejection of his
    petition on two grounds. First, he contends that his trial counsel was
    constitutionally ineffective in investigating and presenting to the jury a case in
    mitigation of the death penalty. Second, he contends the Florida courts’
    determination that he was not intellectually disabled (and therefore ineligible for
    the death penalty) constituted an unreasonable application of clearly established
    law and was based on an unreasonable determination of the facts presented at an
    evidentiary hearing.
    After a thorough review of the briefing and the record, and with the benefit
    of oral argument, we affirm the denial of Arbelaez’s petition.1 With regard to the
    ineffective assistance claim, we conclude that Arbelaez has failed to demonstrate
    that his counsel’s performance prejudiced his penalty phase proceedings. As
    regards his intellectual disability claim, we conclude he has failed to demonstrate
    that the Florida Supreme Court unreasonably applied the law or made unreasonable
    1
    Arbelaez’s motion to stay further appellate proceedings is DENIED. All other pending
    motions are DENIED AS MOOT.

    determinations of fact when it concluded that he lacked concurrent deficits in
    adaptive behavior.
    I.     FACTUAL BACKGROUND
    Arbelaez was convicted in Florida of kidnapping and first degree murder. A
    jury voted 11 to 1 to recommend a death sentence, and the trial court accepted the
    recommendation. Below we recount the events that led to Arbelaez’s conviction
    and sentence, as well as evidence adduced at his state postconviction proceedings.
    A. Facts Elicited at Trial
    Shortly after Arbelaez met Graciela Alfara, the victim Julio Rivas’s mother,
    he moved in with her and her family (five year old Julio, two teenaged daughters,
    and a nineteen year old cousin), and the two became intimate. See Arbelaez v.
    State (“Arbelaez I”), 
    626 So. 2d 169
    , 170 (Fla. 1993). The relationship ended soon
    after it began, however, when Alfara accused Arbelaez of touching one of her
    daughters inappropriately. 
    Id. Shortly after
    the breakup, Arbelaez saw Alfara kiss
    another man. 
    Id. When he
    confronted her, Alfara told Arbelaez that she did not
    love him and he should move out. 
    Id. The next
    morning, while Alfara was still asleep, Arbelaez took Julio from
    the home. 
    Id. at 171.
    Arbelaez drove to a restaurant for coffee. 
    Id. Leaving Julio
    in the car, Arbelaez went inside, where he spoke to his friend Juan Londrian about
    3
    Case: 14-14647     Date Filed: 10/12/2016    Page: 4 of 27
    his fight with Alfara. 
    Id. Londrian testified
    at trial that Arbelaez told him “that he
    was going to do something that would assure ‘that bitch is going to remember me
    for the rest of her life.’” 
    Id. Arbelaez left
    the restaurant and, after driving around
    with Julio in the car for a couple of hours, attempted to call Alfara. 
    Id. When Alfara
    refused to speak with him, he “drove to the crest of the Powell Bridge on
    the Rickenbacker Causeway and stopped, exited his car, and lifted the hood,
    pretending that his car had broken down.” 
    Id. There, he
    threw Julio off the bridge
    into the water 70 feet below. 
    Id. According to
    evidence introduced at trial, Julio was beaten and strangled
    before he was thrown off the bridge. 
    Id. at 173-74.
    A medical examiner testified
    that the cause of death was asphyxia resulting from both strangulation and
    drowning and that the boy’s body “had a large bruise on the right leg” and
    “numerous bracket-shaped and rectangular-shaped bruises on the left side” of the
    body. 
    Id. at 174.
    “The child’s face and forehead also had numerous linear
    abrasions consistent with it being knocked or pressed into something.” 
    Id. The jury
    saw photographs of Julio’s body which depicted his injuries. When police
    located Arbelaez’s car, they observed damage to the dashboard “consistent with
    something coming into contact with the panel.” 
    Id. at 171.
    The jury heard that Arbelaez confessed to the crime five times. Immediately
    after the murder, Arbelaez confessed to a friend, Pedro Salazar. He told Salazar
    4
    Case: 14-14647    Date Filed: 10/12/2016    Page: 5 of 27
    “that he ‘shook’ the child and ‘squeezed the boy’s neck.’” 
    Id. He also
    told Salazar
    that he threw Julio off the bridge because he wanted revenge against Alfara. 
    Id. Arbelaez fled
    to Colombia, and while there he spoke with Federal Bureau of
    Investigation Detective Rubin Munoz. 
    Id. at 172.
    Arbelaez gave his second
    confession to Munoz, telling the detective that he had killed Julio and explaining:
    “‘As a Latin you would understand the best way to get to a woman is through her
    children.’” 
    Id. When Arbelaez
    returned voluntarily to the United States two months after
    the murder, Homicide Detective Eddy Martinez arrested him at the airport. 
    Id. at 173.
    While in custody, Arbelaez confessed three more times to Julio’s murder. In
    his third confession, “Arbelaez stated that on the day of the murder he had stopped
    [on the bridge], raised the hood in order to pretend that he was stranded, and then
    threw the child off the bridge.” 
    Id. The fourth
    confession, which was audiotaped,
    was similar in content. The fifth, also similar in content, was videotaped. In each
    taped interview, “Arbelaez indicated that he killed the child as a plan of revenge
    against [Alfara].” 
    Id. Despite these
    confessions, Arbelaez testified on his own behalf at trial,
    where he denied committing the murder. Although he admitted taking Julio from
    Alfara’s house, he said that he had car trouble on the bridge, forgot about Julio
    when he went to look under his hood, heard a scream, and then saw Julio floating
    5
    Case: 14-14647    Date Filed: 10/12/2016    Page: 6 of 27
    in the water below. 
    Id. at 174.
    Arbelaez testified that he tore his car’s dashboard
    apart because he was “disgusted with it all.” 
    Id. When confronted
    with his prior
    confessions, Arbelaez claimed that Salazar, Munoz, and Martinez were lying. 
    Id. The jury
    found Arbelaez guilty of kidnapping and first degree murder. 
    Id. B. Sentencing
    Proceedings
    At the sentencing phase, the State called no witnesses to testify. Defense
    counsel presented six witnesses in mitigation. Detective Martinez testified that, to
    his knowledge, Arbelaez had no significant criminal history and returned
    voluntarily to the United States after he had fled to Colombia. 
    Id. Four other
    witnesses—Londrian, Pedro Salazar, Adelfa Salazar, and Marta Salazar—testified
    about their relationship with Arbelaez. Each testified that Arbelaez was an honest,
    hard-working individual who never took narcotics or drank excessively. 
    Id. A sixth
    witness, neurologist Dr. Raul Lopez, testified that he treated Arbelaez for
    “chronic epileptic seizures” a few years before the murder. 
    Id. at 174-75.
    The jury recommended a death sentence by a vote of 11 to 1. 
    Id. at 175.
    The trial judge found three aggravating circumstances: the homicide was (1)
    committed in a cold, calculated, and premeditated manner without any pretense of
    moral or legal justification (“CCP”); (2) especially heinous, atrocious, or cruel
    (“HAC”); and (3) committed while Arbelaez was engaged in a kidnapping. Fla.
    Stat. § 921.141(5)(d), (h), (i) (1989). The judge found one statutory mitigating
    6
    Case: 14-14647        Date Filed: 10/12/2016       Page: 7 of 27
    circumstance: Arbelaez had no significant history of prior criminal history. 
    Id. § 921.141(6)(a).
    And the judge found one nonstatutory mitigating circumstance:
    Arbelaez demonstrated remorse. After weighing these factors, the judge adopted
    the jury’s recommendation and imposed a death sentence.
    C. Direct Appeal and State Postconviction Proceedings
    The Florida Supreme Court affirmed Arbelaez’s convictions and sentence on
    direct appeal. Arbelaez I, 
    626 So. 2d 169
    , cert. denied, 
    114 S. Ct. 2123
    (1994).
    Arbelaez then initiated state postconviction proceedings. His first proceeding
    concerned his claim that counsel rendered ineffective assistance in failing to
    investigate and present an adequate case in mitigation of the death penalty. After
    the Supreme Court held in Atkins v. Virginia, 
    536 U.S. 304
    (2002), that the Eighth
    Amendment prohibits the execution of intellectually disabled persons, Arbelaez
    initiated another state proceeding alleging that he was intellectually disabled.
    1. Ineffective Assistance Postconviction Motion
    The trial court conducted an evidentiary hearing2 on Arbelaez’s ineffective
    assistance claim at which postconviction counsel elicited testimony from several
    2
    This evidentiary hearing came after the trial court initially summarily denied relief and
    the Florida Supreme Court remanded. See Arbelaez v. State, 
    775 So. 2d 909
    (Fla. 2000).
    7
    Case: 14-14647        Date Filed: 10/12/2016        Page: 8 of 27
    witnesses, including trial counsel Reemberto Diaz, 3 clinical and forensic
    psychologist Dr. Merry Haber, neuropsychologist and behavioral epileptologist Dr.
    Ruth Latterner, and two of Arbelaez’s sisters.
    Arbelaez’s sisters testified about Arbelaez’s troubled childhood in
    Colombia. Both testified that Arbelaez suffered severe physical abuse at the hands
    of their father and, to a lesser extent, their mother, brother, and at least one teacher.
    They recounted that their family was poor and the children often went hungry.
    Arbelaez’s sisters further testified that Arbelaez was a slow learner at school,
    endured epileptic episodes without medical treatment, experienced depression (and
    abused marijuana to cope), attempted suicide several times, and spent time in a
    mental hospital.
    Postconviction counsel’s experts testified about Arbelaez’s mental health
    and intellectual functioning. Dr. Haber testified that, when she screened Arbelaez
    prior to trial at counsel’s behest, she believed Arbelaez to be of borderline
    intelligence. She suspected that, based on Arbelaez’s epilepsy, he likely has
    organic brain impairment.4 She testified that Arbelaez showed signs of a
    3
    Because we assume for purposes of analyzing this claim under the test set forth in
    Strickland v. Washington, 
    466 U.S. 668
    (1984), that trial counsel performed deficiently, we do
    not recount Diaz’s testimony.
    4
    Postconviction counsel introduced Dr. Haber’s testimony in large part to demonstrate
    that trial counsel was deficient in failing to investigate red flags about Arbelaez’s mental health
    and family history. We do not recount her testimony relevant to deficient performance because
    of our assumption for purposes of this opinion that counsel’s performance was deficient under
    8
    Case: 14-14647        Date Filed: 10/12/2016      Page: 9 of 27
    depressive disorder and previously had undergone electroshock therapy in
    Colombia while hospitalized after a suicide attempt. Dr. Latterner, who evaluated
    Arbelaez in preparation for the evidentiary hearing, testified that Arbelaez is
    intellectually disabled and suffers from epilepsy and organic brain damage. The
    State called clinical psychologist Dr. Sonia Ruiz, who testified that she did not
    believe Arbelaez is intellectually disabled or suffers from organic brain
    impairment.
    The trial court rejected Arbelaez’s ineffective assistance claim, and the
    Florida Supreme Court affirmed. See Arbelaez v. State, 
    898 So. 2d 25
    , 41 (Fla.
    2005). The Florida Supreme Court divided Arbelaez’s ineffective assistance claim
    into subclaims—failure to investigate and present evidence of (1) epilepsy, (2)
    other mental health mitigation, and (3) family history—and then analyzed deficient
    performance and prejudice individually for each one. With respect to epilepsy, the
    Florida Supreme Court concluded that Arbelaez failed to show counsel performed
    deficiently or that any deficiency prejudiced him. See Strickland v. Washington,
    
    466 U.S. 668
    , 687 (1984) (explaining that, to establish ineffective assistance of
    counsel, the defendant “must show that counsel’s performance was deficient” and
    “that the deficient performance prejudiced the defense”). As to other mental health
    Strickland. To be clear, we do not decide whether trial counsel was deficient but only assume it
    for purposes of this opinion.
    9
    Case: 14-14647        Date Filed: 10/12/2016        Page: 10 of 27
    mitigation, the court concluded that, although counsel’s performance was deficient,
    Arbelaez could not demonstrate prejudice. With respect to family history, the
    Florida Supreme Court held that counsel’s performance was not deficient. The
    court did not address prejudice as it pertained to this subclaim. 5
    2. Intellectual Disability Postconviction Motion
    In a separate proceeding, the trial court conducted an evidentiary hearing on
    Arbelaez’s claim that he is intellectually disabled and therefore ineligible for the
    death penalty. 6 Specifically, the court conducted the hearing to determine whether
    Arbelaez satisfied Florida’s definition of intellectual disability, that is,
    “significantly subaverage general intellectual functioning existing concurrently
    with deficits in adaptive behavior and manifested during the period from
    conception to age 18.” Fla. R. Crim. P. 3.203; see 
    Atkins, 536 U.S. at 317
    (“[W]e
    leave to the States the task of developing appropriate ways to enforce the
    constitutional restriction upon their execution of sentences.” (alterations and
    internal quotation marks omitted)).
    As relevant to this appeal, postconviction counsel proffered testimony from
    psychologist Dr. Ricardo Weinstein and educational psychologist Dr. Thomas
    5
    After the Florida Supreme Court denied relief, Arbelaez did not petition the Supreme
    Court of the United States for a writ of certiorari.
    6
    As with his ineffective assistance of counsel hearing, Arbelaez’s intellectual disability
    hearing also came after the trial court summarily denied this claim and the Florida Supreme
    Court remanded for a hearing. See Arbelaez v. State, 
    950 So. 2d 413
    (Fla. 2006).
    10
    Case: 14-14647       Date Filed: 10/12/2016      Page: 11 of 27
    Oakland to support the claim that Arbelaez is intellectually disabled.7 The State
    presented the testimony of psychologist Dr. Enrique Suarez. Court appointed
    expert Dr. Sonia Ruiz, a forensic psychologist (who had testified at Arbelaez’s
    ineffective assistance evidentiary hearing), also testified. Both Dr. Suarez and Dr.
    Ruiz testified Arbelaez was not intellectually disabled, and thus their conclusions
    about Arbelaez’s intellectual functioning contradicted the opinions of Arbelaez’s
    experts.After evaluating Arbelaez, Dr. Weinstein opined that he was intellectually
    disabled. Dr. Weinstein obtained an intellectual quotient (“IQ”) score of 65, which
    he testified qualified as significantly subaverage general intellectual functioning.
    As to deficits in adaptive behavior, Dr. Weinstein testified that he did not formally
    assess Arbelaez’s deficits concurrent with the IQ evaluation, although he generally
    observed some deficits during the evaluation.
    According to Dr. Weinstein, people with intellectual disabilities are poor
    self-reporters of their own adaptive functioning, so it is best to obtain this
    information from the individual’s community. Dr. Weinstein opined that, due to
    its restrictive environment, a prison cannot constitute a community and prison
    guards would be inappropriate subjects for his interviews. Dr. Oakland agreed
    with Dr. Weinstein that prison was an inappropriate setting for assessing adaptive
    7
    Arbelaez’s counsel also called several laywitnesses, including friends and family who
    knew Arbelaez in Colombia or Florida and three corrections officers who had observed Arbelaez
    in prison. Their testimony is immaterial to the issues we address here.
    11
    Case: 14-14647     Date Filed: 10/12/2016    Page: 12 of 27
    deficits, testifying that “[i]t is not possible to assess adaptive behavior within the
    setting similar to death row.” So instead, Dr. Weinstein reached his conclusion
    that Arbelaez suffered from concurrent deficits in adaptive behavior based on
    interviews with family members, priests, a teacher, and several friends, as well as a
    review of school, medical, and prison records. He also obtained measures of
    Arbelaez’s adaptive functioning by asking Arbelaez’s mother and a schoolteacher
    to complete the Adaptive Behavior Assessment Scales (“ABAS”), a test used to
    evaluate an individual via members of his community. Based on interviews, the
    ABAS results, and his observations, Dr. Weinstein concluded that Arbelaez had
    concurrent deficits in adaptive functioning. Relying on his interviews with people
    who knew Arbelaez as a child, Dr. Weinstein concluded that Arbelaez had
    significantly subaverage general intellectual functioning and adaptive behavioral
    deficits prior to age 18.
    Dr. Weinstein’s opinion was rejected by the State’s expert, Dr. Suarez, and
    by the court-appointed expert, Dr. Ruiz. Dr. Suarez evaluated Arbelaez and,
    considering information from before and during his incarceration, including formal
    tests of concurrent adaptive functioning, opined that he was not intellectually
    disabled. He based his opinion on the facts that Arbelaez: needed no support to
    function in his daily life (he was able to drive and run errands and he
    communicated with others, even in English); came to this country with relatively
    12
    Case: 14-14647     Date Filed: 10/12/2016    Page: 13 of 27
    little assistance; secured employment and performed adequately; used an alias at
    work; and fled the country after his crime. Dr. Suarez administered a series of tests
    and opined from the results that Arbelaez’s reasoning level was probably in the
    average range.
    Dr. Ruiz testified about her evaluation of Arbelaez during preparation for the
    ineffective assistance of counsel evidentiary hearing. She testified that she did not
    believe Arbelaez was intellectually disabled, but conceded that she relied primarily
    on Arbelaez’s self-reporting. After interviewing Arbelaez, Dr. Ruiz concluded
    Arbelaez was not intellectually disabled because he reported that he had traveled
    alone to Venezuela, the Bahamas, Panama, and Jamaica before coming to the
    United States and had held and performed a variety of jobs before being
    incarcerated. Dr. Ruiz administered a number of tests and reviewed other reports
    and records on Arbelaez. She concluded from her evaluation that Arbelaez had a
    borderline intelligence level, no intellectual disability, and abilities to communicate
    and live independently that were inconsistent with intellectual disability.
    The trial court denied relief, concluding that Arbelaez failed to demonstrate
    significantly subaverage intellectual functioning or concurrent adaptive deficits.
    The Florida Supreme Court affirmed, holding that “Arbelaez did not prove that he
    has concurrent deficits in adaptive behavior as required by” Florida law. Arbelaez

    v. State, 
    72 So. 3d 745
    , 745 (Fla. 2011), cert. denied sub nom., Arbelaez v. Florida,
    
    132 S. Ct. 1950
    (2012).
    D. Federal Habeas Proceeding
    After he had exhausted his state appeals, Arbelaez filed a petition for a writ
    of habeas corpus in federal district court, raising several claims including his
    ineffective assistance and intellectual disability claims. The district court denied
    Arbelaez relief but granted him a certificate of appealability (“COA”) on his claim
    that counsel rendered ineffective assistance at the penalty phase of his trial. We
    expanded Arbelaez’s COA to include his claim that the Florida Supreme Court’s
    intellectual disability determination constituted an unreasonable application of
    clearly established federal law and was based on an unreasonable determination of
    facts in light of the evidence presented at the evidentiary hearing.
    II.   STANDARD OF REVIEW
    “When reviewing a district court’s grant or denial of habeas relief, we
    review questions of law and mixed questions of law and fact de novo, and findings
    of fact for clear error.” Reaves v. Sec’y, Fla. Dep’t of Corr., 
    717 F.3d 886
    , 899
    (11th Cir. 2013) (internal quotation marks omitted).
    The standard by which we and the district court must review the relevant
    state court decisions depends on whether the state court rendered a decision on the
    merits of Arbelaez’s claims. If so, then we review those claims under the
    14
    Case: 14-14647   Date Filed: 10/12/2016   Page: 15 of 27
    standards set by the Antiterrorism and Effective Death Penalty Act of 1996
    (“AEDPA”). Williams v. Taylor, 
    529 U.S. 362
    , 402-03 (2000). Generally,
    AEDPA bars federal courts from granting habeas relief to a petitioner on a claim
    that was adjudicated on the merits in state court unless the state court’s
    adjudication:
    (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). “‘[C]learly established Federal law’ under § 2254(d)(1) is
    the governing legal principle or principles set forth by the Supreme Court at the
    time the state court renders its decision.” Lockyer v. Andrade, 
    538 U.S. 63
    , 71-72
    (2003). With respect to § 2254(d)(2), “[s]tate court fact-findings are entitled to a
    presumption of correctness unless the petitioner rebuts that presumption by clear
    and convincing evidence.” Conner v. GDCP Warden, 
    784 F.3d 752
    , 761 (11th Cir.
    2015).
    If the state courts have not rendered a decision on the merits of a claim, then
    our review is de novo. See Porter v. McCollum, 
    558 U.S. 30
    , 39 (2009) (“Because
    the state court did not decide whether Porter’s counsel was deficient, we review
    this element of Porter’s Strickland claim de novo.”).
    15
    Case: 14-14647     Date Filed: 10/12/2016   Page: 16 of 27
    For the reasons that follow, we review Arbelaez’s ineffective assistance of
    counsel claim de novo and his intellectual disability claim through AEDPA’s
    deferential lens.
    III.   DISCUSSION
    A. Ineffective Assistance of Counsel Claim
    Arbelaez claims that his trial counsel was ineffective in failing to investigate
    and present evidence about his mental health problems and troubled family history
    during the penalty phase and that there is a reasonable probability that, had the jury
    heard that evidence, it would have recommended a sentence other than death.
    Under 
    Strickland, 466 U.S. at 686
    , a defendant has a Sixth Amendment right to
    effective assistance of trial counsel. Counsel renders ineffective assistance,
    warranting vacatur of a conviction or sentence, when his performance falls “below
    an objective standard of reasonableness,” taking into account prevailing
    professional norms, and when “there is a reasonable probability that, but for
    counsel’s unprofessional errors, the result of the proceeding would have been
    different.” 
    Id. at 688,
    694. “A reasonable probability is a probability sufficient to
    undermine confidence in the outcome.” 
    Id. at 694.
    We assume for present purposes that Arbelaez’s trial counsel rendered
    deficient performance in failing to investigate and present a sufficient case in
    mitigation. See Castillo v. Fla., Sec’y of DOC, 
    722 F.3d 1281
    , 1283-84 (11th Cir.
    16
    Case: 14-14647     Date Filed: 10/12/2016   Page: 17 of 27
    2013) (making “simplifying assumptions in favor of the petitioner” to facilitate the
    Court’s analysis, including assuming deficient performance and deciding
    Strickland’s prejudice prong only). Thus, we must decide whether counsel’s
    deficient performance prejudiced Arbelaez in the penalty phase of his trial,
    considering in addition to the testimony counsel actually elicited at the penalty
    phase the mental health and family history mitigating evidence adduced at the
    postconviction evidentiary hearing.
    Although the Florida Supreme Court decided on the merits the prejudice
    prong of one subclaim—failure to investigate and present mental health mitigation
    evidence—it failed to assess prejudice as it pertained to counsel’s failure to
    investigate and present evidence of Arbelaez’s family background. We thus are
    left with a situation in which part of our prejudice inquiry may require deference to
    the Florida Supreme Court’s decision, while part may not. We need not resolve
    how to apply AEDPA deference to the Florida Supreme Court’s decision, however,
    because even under de novo review Arbelaez cannot demonstrate that counsel’s
    failure to investigate and present this mitigating evidence prejudiced his defense.
    See 
    id. Moreover, we
    consider as one claim rather than as independent subclaims
    Arbelaez’s contention that counsel failed to investigate and present adequate
    evidence in mitigation; this evidence is inherently interrelated. See Wiggins v.
    Smith, 
    539 U.S. 510
    , 534-35 (2003) (considering mitigating evidence of
    17
    Case: 14-14647       Date Filed: 10/12/2016       Page: 18 of 27
    petitioner’s “diminished mental capacities” together with his “troubled history” in
    deciding whether counsel’s deficient performance prejudiced his defense).
    We conclude that Arbelaez suffered no prejudice from his counsel’s failure
    to present mitigation testimony from his sisters and mental health experts.
    Arbelaez’s sisters testified that he suffered from an extremely physically abusive
    and impoverished childhood. They and Arbelaez’s mental health experts testified
    that Arbelaez had epilepsy with organic brain damage, was depressed, had
    attempted suicide, and had low intellectual functioning. All of these circumstances
    indisputably are mitigating. See 
    id. Nevertheless, when
    we consider this new
    mitigating evidence together with the mitigation evidence actually presented at
    trial—that Arbelaez was hard working and lacked any significant criminal
    history—and weigh it against the evidence in aggravation, we cannot conclude that
    Arbelaez has met Strickland’s standard for prejudice.8
    “This is not a case where the weight of the aggravating circumstances or the
    evidence supporting them was weak.” Sochor v. Sec’y, Dep’t of Corr., 
    685 F.3d 1016
    , 1030 (11th Cir. 2012) (internal quotation marks omitted). After the jury
    recommended a death sentence, the trial judge found that the prosecution proved
    three statutory aggravators, including CCP and HAC. The Florida Supreme Court
    8
    The trial judge also concluded that Arbelaez demonstrated remorse but, in light of
    Arbelaez’s denial of any involvement of the crime at trial, understandably assigned that
    mitigating factor little weight.
    18
    Case: 14-14647     Date Filed: 10/12/2016   Page: 19 of 27
    “has consistently recognized that CCP and HAC are two of the weightiest
    aggravators in Florida’s statutory sentencing scheme.” Brown v. State, 
    143 So. 3d 392
    , 405 (Fla. 2014). The evidence postconviction counsel introduced would not
    have reduced the impact of these powerful aggravators sufficient to undermine our
    confidence in the outcome of Arbelaez’s penalty phase proceedings.
    The new mitigating evidence would not have mitigated the strength of the
    HAC aggravator, which “‘pertains more to the nature of the killing and the
    surrounding circumstances’” than the defendant’s mental state. Hardwick v. Sec’y,
    Fla. Dep’t of Corr., 
    803 F.3d 541
    , 561 (11th Cir. 2015) (quoting Stano v. State,
    
    460 So. 2d 890
    , 893 (Fla. 1984)). Evidence introduced at trial demonstrated that
    five year old Julio was kidnapped, driven around for several hours, beaten,
    strangled, and thrown 70 feet into the water, where he drowned. The jury saw
    photographs that demonstrated the extent of Julio’s injuries, including photographs
    of his body and the damaged dashboard of Arbelaez’s car.
    Similarly, the mitigating evidence regarding Arbelaez’s mental health and
    troubled childhood is insufficient to undermine substantially the strength of the
    evidence supporting the CCP aggravator in this case. The jury heard that Arbelaez
    told a friend before the murder that he was going to “assure ‘that bitch is going to
    remember me for the rest of her life,’” referring to Alfara. Arbelaez 
    I, 626 So. 2d at 171
    . The jury heard about not one, not two, but five confessions Arbelaez gave,
    19
    Case: 14-14647     Date Filed: 10/12/2016    Page: 20 of 27
    including two confessions in Arbelaez’s own recorded voice. These confessions
    likely were extraordinarily powerful evidence in aggravation. Remarkably
    consistent in their chilling details—Arbelaez repeatedly explained that he
    murdered Julio to exact revenge upon the child’s mother—these confessions
    provided the jury with a concrete basis on which to conclude that the murder was
    cold, calculated, and premeditated.
    In sum, evidence of Arbelaez’s mental health and troubled family
    background undoubtedly would have been mitigating. Even so, in light of the
    highly aggravated nature of the crime at issue in this case, we conclude that there is
    no reasonable probability that the evidence would have convinced the jury to
    recommend a sentence other than death. See Crawford v. Head, 
    311 F.3d 1288
    ,
    1322 (11th Cir. 2002) (concluding upon a de novo review that evidence of a
    defendant’s alcoholic father and disadvantaged childhood, although mitigating,
    would not overcome an “extremely aggravated” murder). Accordingly, we affirm
    the denial of relief on Arbelaez’s ineffective assistance of counsel claim.
    B. Intellectual Disability Claim
    The Eighth Amendment to the United States Constitution prohibits the
    execution of the intellectually disabled. 
    Atkins, 536 U.S. at 321
    . Consistent with
    Atkins, we look to Florida law for the applicable definition of intellectual
    disability. See Holladay v. Allen, 
    555 F.3d 1346
    , 1353 (11th Cir. 2009). Florida
    20
    Case: 14-14647        Date Filed: 10/12/2016       Page: 21 of 27
    law defines intellectual disability as “significantly subaverage general intellectual
    functioning existing concurrently with deficits in adaptive behavior and manifested
    during the period from conception to age 18.” Fla. R. Crim. P. 3.203.
    “[S]ignificantly subaverage general intellectual functioning” means “performance
    that is two or more standard deviations from the mean score on a standardized
    intelligence test.” 
    Id. We assume
    for purposes of this opinion that Arbelaez meets
    this requirement, see 
    Castillo, 722 F.3d at 1283-84
    , and consider the adaptive
    behavior deficiency prong.
    “[A]daptive behavior” means “the effectiveness or degree with which an
    individual meets the standards of personal independence and social responsibility
    expected of his or her age, cultural group, and community.” Fla. R. Crim. P.
    3.203. The American Association of Intellectual and Developmental Disabilities’
    (“AAIDD”) definition of intellectual disability, with which Florida’s definition is
    consistent, defines adaptive deficits as “‘limitations in two or more of the
    following applicable adaptive skill areas: communication, self-care, home living,
    social skills, community use, self-direction, health and safety, functional
    academics, leisure, and work.’” 
    Atkins, 536 U.S. at 308
    n.3 (quoting AAIDD
    definition in effect in 2002). 9
    9
    Defense expert Dr. Marc Tasse conceded that Florida’s definition of intellectual
    disability, including a requirement of concurrent adaptive deficits, was consistent with the
    21
    Case: 14-14647        Date Filed: 10/12/2016       Page: 22 of 27
    The Florida Supreme Court denied on the merits Arbelaez’s intellectual
    disability claim, so we review it under AEDPA’s deferential standard of review.
    Arbelaez contends that the Florida Supreme Court’s decision is not entitled to
    deference because it was based on an unreasonable application of clearly
    established federal law, § 2254(d)(1), and an unreasonable determination of the
    facts, § 2254(d)(2). We disagree.
    1. Florida Supreme Court’s Application of Clearly Established Federal
    Law
    Arbelaez contends that Florida’s requirement that a petitioner demonstrate
    concurrent deficits in adaptive behavior contravenes Atkins and the Supreme
    Court’s later decision in Hall v. Florida, 
    134 S. Ct. 1986
    (2014). 10 He argues that
    these cases, taken together, require states to conform their definitions of
    intellectual disability to accepted medical and professional standards. And,
    definitions used by the AAIDD and the Diagnostic and Statistical Manual of Mental Disorders,
    4th Edition. “Earlier publications of the AAIDD [such as the one quoted in Atkins] were
    published under its former name, the American Association on Mental Retardation.” Hall v.
    Florida, 
    134 S. Ct. 1986
    , 2003 n.1 (2014).
    10
    In Hall, the Supreme Court held that Florida’s rigid rule foreclosing “all further
    exploration of intellectual disability” if a petitioner is deemed to have an IQ above 70 was
    
    unconstitutional. 134 S. Ct. at 1990
    . But Hall was decided after the Florida Supreme Court
    rendered its decision on Arbelaez’s intellectual disability postconviction motion, so it was not a
    “governing legal principle” at that time. 
    Andrade, 538 U.S. at 71-72
    . We conclude, however,
    that the Florida Supreme Court’s decision withstands our deferential review even if Hall applied
    retroactively. See 
    Castillo, 722 F.3d at 1283-84
    .
    22
    Case: 14-14647     Date Filed: 10/12/2016    Page: 23 of 27
    Arbelaez asserts, medical and professional standards dictate that adaptive deficits
    cannot be determined adequately in a prison environment.
    We acknowledge Arbelaez’s concern about the difficulties attendant in
    assessing deficits in adaptive behavior in a restrictive carceral environment. See
    Hall v. State, No. SC10-1335, __ So. 3d __, 
    2016 WL 4697766
    , at *7 (Fla. Sept. 8,
    2016) (“Evaluating the adaptive behavior of an individual who has spent much of
    his adult life incarcerated can be difficult.”). But the question before us is not
    whether we would render a different decision on Arbelaez’s claim than the Florida
    Supreme Court. 
    Andrade, 538 U.S. at 75
    . Rather, to overcome AEDPA’s
    deferential standard of review, Arbelaez “must show that the state court’s
    ruling . . . was so lacking in justification that there was an error well understood
    and comprehended in existing law beyond any possibility for fairminded
    disagreement.” Harrington v. Richter, 
    562 U.S. 86
    , 103 (2011).
    Arbelaez cannot make this showing. Nothing in the holdings of Atkins or
    Hall speaks directly to the methodology for discerning an individual’s deficits in
    adaptive functioning. See 
    Williams, 529 U.S. at 412
    (emphasizing that the phrase
    “‘clearly established Federal law, as determined by the Supreme Court of the
    United States’ . . . refers to the holdings, as opposed to the dicta,” of the Supreme
    Court’s decisions). The Florida Supreme Court’s determination that United States
    Supreme Court precedent is consistent with Florida’s requirement that a petitioner
    23
    Case: 14-14647     Date Filed: 10/12/2016    Page: 24 of 27
    show concurrent deficits in adaptive functioning is not, therefore, beyond any
    fairminded disagreement.
    2. Florida Supreme Court’s Determination of Facts
    Arbelaez also contends that the Florida Supreme Court’s decision that he is
    not intellectually disabled rests on an unreasonable factual determination. Again,
    we assume for our purposes that Arbelaez has satisfied the required showing of
    significantly subaverage intellectual functioning, so we do not address the trial
    court’s denial on that ground. With respect to its findings on adaptive functioning,
    Arbelaez argues that the Florida Supreme Court’s decision was premised on three
    flawed factual determinations. He asserts that the decision: (1) ignored that Dr.
    Weinstein informally observed deficits in Arbelaez’s adaptive behavior during his
    evaluation, (2) disregarded much or all of Dr. Weinstein’s findings regarding
    Arbelaez’s adaptive functioning leading up to his incarceration, and (3)
    unreasonably rejected Dr. Weinstein’s use of the ABAS as a retrospective measure
    of adaptive functioning.
    “A determination as to whether a person is [intellectually disabled] is a
    finding of fact.” Fults v. GDCP Warden, 
    764 F.3d 1311
    , 1319 (11th Cir. 2014).
    We may only disturb a state court’s factual findings if they are unreasonable. “The
    term ‘unreasonable’ is no doubt difficult to define.” 
    Williams, 529 U.S. at 410
    .
    Nonetheless, “it is enough to reiterate that a state-court factual determination is not
    24
    Case: 14-14647     Date Filed: 10/12/2016    Page: 25 of 27
    unreasonable merely because the federal habeas court would have reached a
    different conclusion in the first instance.” Burt v. Titlow, 
    134 S. Ct. 10
    , 15 (2013)
    (internal quotation marks omitted). Thus, “even if reasonable minds reviewing the
    record might disagree about the finding in question, on habeas review that does not
    suffice to supersede the trial court’s determination.” Wood v. Allen, 
    558 U.S. 290
    ,
    302 (2010) (alterations and internal quotation marks omitted).
    Arbelaez cannot demonstrate that the Florida Supreme Court’s conclusion
    that he lacks deficits in adaptive behavior was based on an unreasonable
    determination of the facts introduced at the evidentiary hearing. Under Florida
    law, a person is intellectually disabled only if he has deficits in adaptive behavior
    existing concurrently with significantly subaverage general intellectual
    functioning. Although Dr. Weinstein made observations of Arbelaez’s adaptive
    behavior during the in-prison evaluation, he conceded that he failed to use any
    formal measure to assess Arbelaez’s adaptive functioning concurrent with the IQ
    testing. By contrast, Dr. Suarez assessed Arbelaez’s adaptive behavior both
    retrospectively and concurrently with intellectual functioning testing, concluding
    that Arbelaez lacked the requisite adaptive behavioral deficits. Because the basis
    for Dr. Suarez’s opinion more closely tracked Florida’s definition of intellectual
    disability, the Florida Supreme Court was entitled to credit Dr. Suarez’s opinion
    over Dr. Weinstein’s.
    25
    Case: 14-14647   Date Filed: 10/12/2016   Page: 26 of 27
    Given that it was reasonable to credit Dr. Suarez’s opinion over Dr.
    Weinstein’s based on Dr. Weinstein’s failure to formally assess concurrent
    adaptive deficits, Arbelaez’s other two points of dispute with the factual findings
    regarding his intellectual disability claim also must fail. Those arguments pertain
    to the soundness of Dr. Weinstein’s retrospective study of adaptive functioning,
    which the Florida Supreme Court reasonably decided was insufficient for a reliable
    opinion on concurrent deficits in adaptive behavior. Thus, as the district court
    concluded, “even if Arbelaez had proved [through Dr. Weinstein’s evaluation] that
    he had adaptive deficits while growing up in Colombia and during the time he
    lived in Florida,” “he has not shown that the Florida Supreme Court’s
    determination that he failed to prove concurrent adaptive deficits at the time of the
    intellectual quotient testing was an unreasonable determination of facts.” Arbelaez
    v. Crews, 
    43 F. Supp. 3d 1271
    , 1297 (S.D. Fla. 2014).
    Because Arbelaez was unable to pierce AEDPA deference, we are required
    to defer to the Florida Supreme Court’s determination that he is not intellectually
    disabled. Accordingly, we affirm the denial of relief on Arbelaez’s intellectual
    disability claim.
    IV.    CONCLUSION
    The district court’s denial of Arbelaez’s petition for a writ of habeas corpus
    is affirmed.
