    2                       Opinion of the Court                20-11271
    Before JORDAN, BRANCH, and LUCK, Circuit Judges.
    BRANCH, Circuit Judge:
    Keith Gavin is an Alabama prisoner serving two death
    sentences and a term of life imprisonment following his 1999 jury
    convictions on two counts of capital murder and one count of
    attempted murder.         After pursuing a direct appeal and
    postconviction relief in the Alabama state courts, Gavin filed a
    federal habeas petition under 
    28 U.S.C. § 2254
    , alleging, in relevant
    part, that his counsel rendered constitutionally ineffective
    assistance during the penalty phase and that the jurors engaged in
    premature deliberations before the penalty phase in violation of his
    constitutional right to a fair trial. The district court denied relief
    on Gavin’s juror misconduct claim, but it concluded that the state
    court’s determination that counsel was not ineffective was an
    unreasonable application of Strickland v. Washington, 
    466 U.S. 668
    (1984). Accordingly, the district court conditionally granted Gavin
    habeas relief on his ineffective-assistance claim, unless Alabama
    initiated new sentencing proceedings within 90 days of the order.
    The Commissioner of the Alabama Department of
    Corrections (“Alabama”) appeals the grant of habeas relief. Gavin
    cross-appeals, arguing that the district court correctly granted
    habeas relief on his ineffective-assistance claim. In the alternative,
    he argues that habeas relief is warranted on his juror misconduct
    claim. After review and with the benefit of oral argument, we
    reverse the district court’s decision granting habeas relief on
    USCA11 Case: 20-11271             Date Filed: 07/14/2022     Page: 3 of 53
    20-11271                 Opinion of the Court                             3
    Gavin’s ineffective-assistance claim because the state court’s
    determination that counsel was not ineffective during the penalty
    phase was not contrary to, or based on an unreasonable application
    of, Strickland. As for Gavin’s cross-appeal, we affirm the denial of
    habeas relief for the juror misconduct claim.
    I.       Background
    A. The Guilt Phase of Trial
    In 1998, an Alabama grand jury indicted Gavin on two
    counts of capital murder in connection with the murder of William
    Clayton, Jr., and one count of attempted murder in connection
    with shooting at a law enforcement officer. Gavin v. State, 
    891 So. 2d 907
    , 926 (Ala. Ct. Crim. App. 2003). The murder of Clayton
    constituted two capital counts because (1) it was committed during
    the course of a robbery in the first degree, and (2) Gavin had been
    convicted of another murder within the previous 20 years. 1 See
    Ala. Code § 13A-5-40(a)(2), (13) (1975). Attorneys H. Bayne Smith
    and John H. Ufford, II, were appointed to represent Gavin at trial.
    At Gavin’s November 1999 trial, the evidence established
    that the victim, Clayton, was a courier driver for Corporate Express
    Delivery Systems, Inc. Gavin, 
    891 So. 2d at 927
    . On the evening
    of March 6, 1998, after completing his deliveries, Clayton stopped
    1
    In 1982, Gavin was convicted of murder in Illinois and served 17 years of a
    34-year sentence. Gavin, 
    891 So. 2d at 930
    . Gavin was on parole for the 1982
    murder at the time of the Alabama murder.

    at a Regions Bank to use an ATM. 
    Id.
     Eyewitnesses, including
    Gavin’s cousin, Dewayne Meeks,2 testified that Gavin approached
    Clayton’s van parked outside the bank, shot Clayton, got into the
    van, and then drove off. 
    Id.
    An investigator with the local district attorney’s office heard
    about the shooting over the radio and witnessed the van matching
    the description pass him. 
    Id. at 928
    . He pursued the van. 
    Id.
     When
    he turned on his emergency lights, the van stopped in the middle
    of the road, the driver got out, turned toward the investigator, and
    began shooting before running off into the woods. 
    Id.
     The
    investigator discovered Clayton in the van, barely alive, and called
    2
    Meeks was also indicted for capital murder, but the charge was later
    dismissed. Gavin, 
    891 So. 2d at 928
    . At Gavin’s trial, Meeks testified that he,
    his wife, their children, and Gavin drove from Meeks’s home in Chicago to
    Chattanooga, Tennessee, so that Gavin could meet up with a woman that he
    had met a month earlier in Alabama. 
    Id. at 927
    . When the woman did not
    show up at the arranged meeting place, Gavin asked Meeks to drive him to
    Alabama in hopes of locating the woman. 
    Id.
     Gavin and Meeks were stopped
    at an intersection in Centre, Alabama, when Gavin exited Meeks’s vehicle and
    approached Clayton’s van in the bank parking lot. 
    Id. at 928
    . Meeks thought
    that Gavin planned to ask Clayton for directions, but he witnessed Gavin shoot
    Clayton. 
    Id.
     Meeks fled the scene, returned to the motel, and he and his family
    immediately left for Chicago. 
    Id.
     Meeks was employed by the Illinois
    Department of Corrections and, upon his return to Chicago, he discovered his
    department issued gun was missing. 
    Id.
     Meeks suspected that his gun was the
    gun Gavin used to kill Clayton. 
    Id.
     Meeks reported the gun missing, but he
    did not mention that it might have been used in a crime. 
    Id.
     After discussing
    the incident with several friends, Meeks later contacted Alabama law
    enforcement to report what he knew about Gavin’s crime. 
    Id.

    for an ambulance, but Clayton was pronounced dead upon arrival
    at the hospital. 
    Id. at 929
    . The investigator identified Gavin as the
    person who shot at him. 
    Id.
    Within minutes of the investigator’s encounter with Gavin,
    other law enforcement officers arrived on the scene and searched
    the woods. 
    Id.
     Gavin was discovered in the woods and attempted
    to flee, but he stopped when an officer fired a warning shot. 
    Id.
    Without prompting from the officers, Gavin stated, “I hadn’t shot
    anybody and I don’t have a gun.” 
    Id.
     The gun was found several
    days later near the woods, and ballistics confirmed that bullets
    found in the victim and the van had been fired from the gun. 
    Id. at 930
    . The jury found Gavin guilty on all counts.
    B. The Penalty Phase
    At the penalty phase before the jury, 3 the State offered three
    aggravating circumstances: (1) that Gavin was previously
    3
    In Alabama, the trial court must conduct a separate sentencing hearing “as
    soon as practicable after the defendant is convicted” to determine whether the
    defendant should be sentenced to life imprisonment without parole or to
    death. Ala. Code § 13A-5-45(a). During the sentencing hearing, the parties
    may present evidence of the existence of any aggravating or mitigating
    circumstances. Id. § 13A-5-45(c). Under Alabama law at the time of Gavin’s
    trial, if the jury determined that one or more aggravating circumstances
    existed but that they did not outweigh the mitigating circumstances, it was to
    return an advisory verdict recommending life imprisonment without parole.
    Id. § 13A-5-46(e)(2) (1999). But if the jury determined that one or more
    aggravating circumstances outweighed the mitigating circumstances, it was to
    return an advisory verdict recommending a death sentence. Id. § 13A-5-

    6                         Opinion of the Court                     20-11271
    convicted of another felony involving the use or threat of violence
    to a person (his prior Illinois murder conviction); (2) that Gavin
    committed the murder during the commission of a robbery; and
    (3) that he committed the murder while under a sentence of
    imprisonment for another crime. 4 In support, the State called
    46(e)(3). A death penalty recommendation required a vote of at least 10 of the
    12 jurors. Id. § 13A-5-46(f).
    4
    At the time of Gavin’s sentencing, the following constituted statutory
    aggravating circumstances in Alabama:
    (1) The capital offense was committed by a person under
    sentence of imprisonment;
    (2) The defendant was previously convicted of another capital
    offense or a felony involving the use or threat of violence to
    the person;
    (3) The defendant knowingly created a great risk of death to
    many persons;
    (4) The capital offense was committed while the defendant
    was engaged or was an accomplice in the commission of, or an
    attempt to commit, or flight after committing, or attempting
    to commit, rape, robbery, burglary or kidnapping;
    (5) The capital offense was committed for the purpose of
    avoiding or preventing a lawful arrest or effecting an escape
    from custody;
    (6) The capital offense was committed for pecuniary gain;
    (7) The capital offense was committed to disrupt or hinder the
    lawful exercise of any governmental function or the
    enforcement of laws; or

    20-11271                    Opinion of the Court                           7
    Gavin’s parole officer as a witness, who testified that Gavin was
    released from prison for his 1982 Illinois murder conviction at the
    end of December 1997 and was on parole when he murdered
    Clayton.
    Gavin called two witnesses during the penalty phase—
    minister S.J. Johnson and Gavin’s mother.5
    Johnson testified that he met Gavin approximately 20
    months earlier, shortly after Gavin was arrested and requested that
    someone from the church come and speak with him. Johnson had
    visited Gavin weekly for about an hour each time for the past 20
    months. Johnson explained that, initially, Gavin had “an attitude
    that he was blaming everybody except [himself]” for his
    circumstances and things that had happened. But as time went on,
    Gavin “stopped blaming others so much and he began to see where
    he should take some responsibility.” In Johnson’s opinion, Gavin
    now accepted responsibility for his actions, had shown a desire “to
    do God’s will,” and “was sincerely trying to make changes in his
    life.” Johnson expressed that if Gavin were given life imprisonment
    instead of a death sentence, Gavin had “the potential to cultivate a
    deeper relationship with God and [Johnson] fe[lt] that there [was]
    hope for [Gavin] if he’s given time and opportunity.” Johnson
    (8) The capital offense was especially heinous, atrocious or
    cruel compared to other capital offenses.
    Ala. Code § 13A-5-49 (1999).

    Counsel Smith handled the questioning of these witnesses.

    pleaded for the jury to show Gavin mercy. 6 Finally, Johnson
    expressed his sympathy to Clayton’s family for their loss.
    Gavin’s mother, Annette, testified that Gavin was the
    second of eleven living children. She was a Jehovah’s witness, and
    she raised Gavin with a religious foundation. She stated that Gavin
    was always concerned about other people and concerned with
    “what was fair.” And that “[h]e loves justice, he really does.” She
    pleaded for mercy, asking the jury to spare Gavin’s life, explaining
    that
    I really feel . . . that knowing how he views things,
    that he really has the ability to live as he should live
    because he has taken up that course, you know,
    because he had to, he had to see it, he sees it now.
    And so if he’s given the opportunity, he could help
    others. He could really be a great source of help to
    others and to our Creator.
    In closing argument, the State emphasized the details of the
    1982 Illinois murder and that Gavin showed no mercy then or
    when he committed the Alabama murder. The State maintained
    6
    In asking for mercy, Johnson relied on the Bible, reminding the jury that,
    although the Old Testament stated, “an eye for an eye, tooth for a tooth, soul
    for a soul,” there were many more examples of God’s mercy in the Bible.
    Johnson also pointed out that “[w]e no longer live under the scriptures of the
    Old Testament,” that “Christ’s example was the law of love and mercy,” and
    that “as Christians we live under the law of Christ.”

    20-11271                  Opinion of the Court                               9
    that the death penalty was the appropriate sentence for Gavin’s
    actions.
    Gavin’s counsel argued that the two murders, although
    terrible and unforgiveable, did “not represent the sum total of
    Keith Gavin’s life nor even the majority of it. They represent just
    what they are. A few brief moments of anger that were expressed
    in a terrible way.” He urged the jury to consider Gavin’s family
    and the fact that his family still supported him during the trial, and
    that Gavin requested to speak with a religious advisor after he was
    arrested—factors which pointed to redeeming qualities in Gavin.
    He then emphasized that death is irrevocable and urged the jury to
    grant Gavin mercy.
    Following deliberations, the jury returned a non-binding 10
    to 2 advisory verdict, recommending the death penalty for the two
    capital counts.7 Gavin, 
    891 So. 2d at
    926–27.
    7
    At the time of Gavin’s trial, the jury’s sentencing recommendation was non-
    binding on the trial court, but the trial court was required to “consider” the
    recommendation when determining the appropriate sentence. See Ala. Code
    § 13A-5-47(e) (1999). In other words, Alabama vested “ultimate sentencing
    authority” in the trial judge, provided the trial judge considered the jury’s
    recommendation. Harris v. Alabama, 
    513 U.S. 504
    , 508–09 (1995). Alabama’s
    sentencing scheme did not specify the weight the trial judge should give the
    jury’s recommendation. 
    Id.
    In 2017, Alabama amended its statutes to make the jury’s verdict
    binding. See Ala. Code § 13A-5-46(e) (2018); see also Keaton v. State, case no.

    At the separate sentencing hearing, the trial judge found the
    three aggravating circumstances proffered by the State: (1) that the
    murder was committed while Gavin was under a sentence of
    imprisonment; (2) that Gavin was previously convicted of another
    felony involving the use of violence to the person—the 1982 Illinois
    murder; and (3) that “the capital offense was committed while the
    defendant was engaged in the commission of or attempt to commit
    robbery.” The court found that no statutory mitigating
    amended by Act No. 2017-131, Alabama Acts 2017, to provide that the jury’s
    sentencing verdict in a capital-murder trial is no longer a recommendation but,
    instead, is binding upon the trial court.”).

    circumstances existed. 8 As for non-statutory mitigation,9 the trial
    8
    At the time of Gavin’s sentencing, statutory mitigating circumstances in
    Alabama were as follows:
    (1) The defendant has no significant history of prior criminal
    activity;
    (2) The capital offense was committed while the defendant
    was under the influence of extreme mental or emotional
    disturbance;
    (3) The victim was a participant in the defendant’s conduct or
    consented to it;
    (4) The defendant was an accomplice in the capital offense
    committed by another person and his participation was
    relatively minor;
    (5) The defendant acted under extreme duress or under the
    substantial domination of another person;
    (6) The capacity of the defendant to appreciate the criminality
    of his conduct or to conform his conduct to the requirements
    of law was substantially impaired; and
    (7) The age of the defendant at the time of the crime.
    Ala. Code § 13A-5-51 (1999).
    9
    Under Alabama law, non-statutory mitigating circumstances
    shall include any aspect of a defendant’s character or record
    and any of the circumstances of the offense that the defendant
    offers as a basis for a sentence of life imprisonment without
    parole instead of death, and any other relevant mitigating
    circumstance which the defendant offers as a basis for a
    sentence of life imprisonment with parole instead of death.

    12                        Opinion of the Court                     20-11271
    court noted that it had considered sentencing consultant John
    David Sturman’s memorandum on behalf of Gavin.10 The trial
    court explained that:
    In that memorandum, the defendant’s mother is
    reported to have described the defendant’s life as
    influenced by or subject to a combination of drugs
    and gang violence while living in a Chicago housing
    project. The defendant’s mother also testified at the
    sentence hearing conducted before the jury. The
    defendant’s attorney has advised the Court, however,
    that the defendant denies ever having a drug
    problem. At the sentence hearing conducted before
    the jury, the Court heard testimony of Reverend [S].J.
    Johnson who spoke eloquently on behalf of the
    defendant as a result of his frequent meetings with the
    defendant over the many months of the defendant’s
    incarceration. Reverend Johnson opines that the
    defendant has concern and sympathy for the victim’s
    family, and that the defendant is capable of a closer
    relationship with God. This Court has considered all
    matters presented by the defendant, but this Court
    10
    Sturman’s memorandum stated that Gavin spent the majority of his
    childhood in the housing projects of Chicago. Many of Gavin’s siblings had
    drug problems, and some had been arrested or incarcerated for unspecified
    crimes. Gavin was raised in a nuclear family, grew up in the church, got along
    well with his peers, and maintained stable employment prior to the Illinois
    murder. Gavin’s mother denied any history of mental health issues on either
    side of the family. She stated that the family was exposed to constant street
    violence, drug activity, and gangs in the neighborhood.

    20-11271               Opinion of the Court                      13
    does not find any support for any non-statutory
    mitigating circumstance.
    Thus, the trial court determined that the aggravating
    circumstances outweighed the non-existent mitigating
    circumstances, adopted the jury’s recommendation, and sentenced
    Gavin to death for each of the capital counts, to be followed by a
    consecutive term of life imprisonment for the attempted murder
    count.
    On direct appeal, the Alabama Court of Criminal Appeals
    affirmed Gavin’s conviction and sentence. Gavin, 
    891 So. 2d at 998
    .
    The Alabama Supreme Court denied certiorari, Ex Parte Gavin,
    
    891 So. 2d 998
     (Ala. 2004), as did the United States Supreme Court,
    Gavin v. Alabama, 
    543 U.S. 1123
     (2005).
    C. State Postconviction Proceedings
    Subsequently, Gavin filed a state postconviction petition
    under Alabama Rule of Criminal Procedure 32, arguing, as relevant
    here, that (1) his trial attorneys were constitutionally ineffective
    during the penalty phase for failing to obtain and present
    readily-available mitigating evidence related to his background,
    “childhood, upbringing, family, socio-economic status, or any
    other particularized facts that would have humanized Mr. Gavin
    for the jury”; and (2) the jury committed misconduct when it
    engaged in premature penalty phase deliberations in violation of
    Gavin’s constitutional right to a fair trial.
    USCA11 Case: 20-11271        Date Filed: 07/14/2022      Page: 14 of 53
    14                      Opinion of the Court                  20-11271
    The trial court summarily dismissed the premature jury
    deliberation claim and held an evidentiary hearing on Gavin’s
    ineffective-assistance claim. 11
    Smith, one of Gavin’s trial counsels, was deceased at the
    time of the evidentiary hearing, and Gavin did not call co-counsel
    Ufford as a witness (although there is no indication that Ufford was
    unavailable). Instead, Gavin submitted sworn affidavits from
    Smith and Ufford that they filed in connection with Gavin’s post-
    verdict motion for a new trial in 2000, in which Gavin made similar
    allegations of ineffective assistance of counsel.
    As to the mitigation investigation, Smith attested in his
    affidavit as follows:
    I initiated contact almost immediately with Lucia
    Penland of the Alabama Prison Project (APP) to
    obtain the services of the APP to investigate matters
    involving mitigation. Due to her commitments in
    other capital murder cases which were much further
    along in the trial preparation process, Ms. Penland
    was unable to commit a great deal of time to this
    particular case in its early stages. When Ms. Penland
    was finally able to travel from Montgomery to Centre
    to meet with [Gavin], to discuss possible preparation
    of a mitigation case, [Gavin] adamantly refused to
    discuss mitigation matters, insisting on his innocence

    The same judge who presided over Gavin’s trial and sentencing presided
    over the Rule 32 proceeding.

    20-11271                  Opinion of the Court                             15
    and the fact that he was not at the scene of the crime
    when the shooting took place. He maintained this
    posture throughout the entire preparation phase of
    the case. In fact, Ms. Penland, while in Chicago on
    other business during the summer prior to the trial of
    the case, attempted to contact Defendant’s family for
    purposes of preparation; they refused to speak with
    her, apparently because [Gavin] had not authorized
    them to speak with our defense team. Ultimately, as
    appellate defense counsel is aware, [Gavin’s] mother
    traveled from Chicago to testify in his behalf in the
    sentencing portion of the trial, and we obtained the
    testimony of a local minister with whom the
    Defendant had established a relationship during his
    incarceration in Cherokee County. The testimony is
    a matter of record and I will not attempt to
    characterize it. However, on more than one
    occasion, [Gavin’s] mother summed up her feelings
    by noting that it was a shame her son had no money
    to retain a “real attorney.” 12
    Gavin submitted an affidavit from Minister S.J. Johnson.
    Johnson asserted that Gavin’s counsel first approached him to
    testify three days before the start of the penalty phase. Counsel
    asked only what Johnson’s “impression” of Gavin was and did not
    12
    Co-counsel Ufford stated simply that he “concur[red]” in Smith’s affidavit,
    and that Smith’s affidavit was “an accurate statement of the facts learned and
    the decision making process used and agreed upon by me during the time of
    preparation for the trial.”

    prepare Johnson for testifying. This short five-minute meeting was
    Johnson’s only meeting with counsel.
    Gavin testified at the evidentiary hearing that he was born
    and raised in the housing projects of Chicago and had 11 siblings
    (one of whom was deceased). Gavin’s parents were married and
    both parents lived in the home. His father was a disciplinarian and
    “whooped” Gavin when he did something wrong but social
    services was never involved with his family. Gavin described his
    neighborhood as “pretty safe”—his mother would even leave the
    doors unlocked—but it “started getting bad” when he was
    “[a]round nine or 10 years old.” 13 Gavin denied being involved
    with drugs but confirmed that there was drug activity in the
    neighborhood.
    Gavin dropped out of school in the eleventh grade, but later
    earned his GED and took some college courses while incarcerated
    for the Illinois murder. He was incarcerated in the Illinois state
    prison system from 1982 until December 26, 1997, for murder, and
    he was paroled at age 37 after serving 17 years of his 34-year
    sentence.14 Upon his release, he returned home to Chicago to live
    13
    Gavin acknowledged during his testimony that he may have told Dr. King
    in an interview that things in his neighborhood started changing and getting
    bad when he was slightly older—around 11 or 12 years’ old.
    14
    Gavin was convicted in 1982 of the Illinois murder and paroled in December
    1997, which is approximately 15 years’ imprisonment. Nevertheless, the
    parties agree that Gavin served 17 years of his 34-year sentence for the Illinois
    murder. Gavin’s presentence report indicates that he was arrested in March
    USCA11 Case: 20-11271            Date Filed: 07/14/2022         Page: 17 of 53
    20-11271                   Opinion of the Court                               17
    with his mother, but he could not find work. When he returned to
    his mother’s home after his release, “the house was messy, and
    dirty,” and in a state of disrepair. At the time, his sister Sharon, his
    sister Geanetta, her husband, and their three children were also
    living at his mother’s house. Gavin stated he was distressed and
    depressed with the condition of his mother’s home, and he felt like
    his siblings had let his mother down—he noted that a “couple” of
    his siblings also had drug issues at that time.
    Gavin confirmed that trial counsel hired an investigator to
    work on his case and that the investigator “worked with” Gavin.
    However, Gavin did not provide any testimony about the extent
    of the investigation or his interactions with the investigators.
    Lucia Penland, the mitigation specialist, testified that
    Gavin’s counsel Smith contacted her in October 1998, and shortly
    thereafter, formally retained her services to assist with Gavin’s
    case. According to Penland, Smith did not provide her with any
    background materials concerning Gavin’s life, and she requested
    that he obtain Gavin’s prison records, but he did not. 15 Penland
    1981 for the Illinois murder, and it is possible that Gavin received credit for
    time served while pending trial in the Illinois case. In any event, we accept the
    parties’ contention that he served 17 years of his 34-year sentence for Illinois
    murder before being paroled.
    15
    On cross-examination, Penland admitted that John Sturman, another
    mitigation specialist that she arranged to help with the case, managed to
    obtain “some records,” including Gavin’s educational and prison records, but
    Penland herself never saw those records.
    USCA11 Case: 20-11271        Date Filed: 07/14/2022      Page: 18 of 53
    18                      Opinion of the Court                  20-11271
    interviewed Gavin in April 1999. During that interview, Gavin
    provided her with “basic background information, schools he went
    to, where he lived, . . . whether he had had any medical
    emergency-type injuries, illnesses, that sort of thing, just basic
    information, and including information about his family.”
    However, she admitted that Gavin was uncooperative, kept
    insisting on his innocence, and she “had a difficult time in the initial
    interview . . . with convincing him to give me any information.”
    Because of Gavin’s prior prison sentence for the Illinois murder,
    Penland spoke with Smith about obtaining an expert on the effects
    of institutionalization, and Penland contacted Dr. Craig Haney,
    who was an expert in that field, but Dr. Haney was unavailable at
    the time of trial. Penland testified that Smith did not contact her
    between May and September 1999 to check on her progress.
    At some point between the April 1999 interview with Gavin
    and September, Penland attempted to interview Gavin’s mother,
    but she refused to speak with Penland, and the rest of Gavin’s
    family were uncooperative as well. Penland sought the help of
    fellow mitigation specialist John Sturman who was based in
    Chicago. Sturman had slightly better luck with Gavin’s mother
    and obtained an interview from her.
    In September 1999, Smith informed Penland that Gavin’s
    trial was set for November. Penland told Smith that more work
    needed to be done, and she requested that Smith get another

    continuance. 16 According to Penland, Smith “was not willing to
    ask for a continuance,” and “didn’t believe that he could get one”
    because Smith’s most recent request for a continuance due to his
    broken foot was denied. Approximately two weeks before trial,
    Penland obtained Sturman’s reports and sent them to Smith, again
    expressing her belief that, because of the family’s lack of
    cooperation, there were potential mitigation leads that remained
    unexplored and that Smith should seek a continuance. 
    17 Smith 16
    The record reflects that Smith had obtained at least two prior continuances.
    17
    Penland stated the following:
    Bayne, I am forwarding on to you material from Mr. Sturman
    in Chicago. There are issues that need to be pursued in this
    case, including the atmosphere in which Mr. Gavin grew up,
    the effects of his incarceration, effect of poverty, racism, etc.
    Mr. Sturman said that during the time Mr. Gavin was growing
    up and in the area of town where his family lived, there was a
    great deal of violence, including the development of large
    gangs, and serious gang activity. All of these issues along with
    whatever is found in the family dynamics need to be
    thoroughly explored.
    I would like to urge you again to request a continuance, based
    on the information we are developing, along with the lack of
    cooperation we have encountered, and the time factor on my
    part—having just this Monday finished with a trial on a prior
    case—which has not allowed us to be further along than we
    are at this time. It is not an unreasonable request under the
    circumstances. We need to have time to not only complete
    the preliminary work, but to engage some expertise to help
    present to the jury, and the judge, the issues which go to
    USCA11 Case: 20-11271            Date Filed: 07/14/2022         Page: 20 of 53
    20                         Opinion of the Court                       20-11271
    responded that, although Gavin’s family seemed to be “coming
    around and beginning to cooperate to some extent,” Gavin
    remained unwilling to cooperate, and Smith did not believe that
    another continuance would be granted based on statements from
    the trial court. Penland admitted during the evidentiary hearing
    that Smith did some of his own investigation work, and she was
    unaware of the extent of his investigation.
    Dr. Betty Paramore—a clinical counselor and expert
    mitigation specialist hired by Gavin’s postconviction team to
    develop a mitigation profile—testified to several risk factors and
    positive (“protective”) factors she identified in Gavin’s life
    following interviews with Gavin and his family. 18 She emphasized
    that several of Gavin’s siblings had drug issues, were involved with
    gangs, and had a history of incarceration. Dr. Paramore
    mitigation. An adequate mitigation case can not be developed
    otherwise.
    18
    The risk factors included “multi-generational family dysfunction”; large
    family size; parental criminality (Gavin’s father was incarcerated for nine
    months for robbery when Gavin was two years old); low-socioeconomic
    status and poverty; Gavin’s exposure to domestic violence and physical abuse
    as a child (family members reported Gavin’s father was “a strong
    disciplinarian” that gave “whippings” with “extension cords, sticks, hoses, [his]
    fist, and other items . . . within [his] reach”—although notably Gavin denied
    any abuse as a child); Gavin’s exposure to race riots and racial tension in his
    neighborhood following the assassination of Dr. Martin Luther King; and
    exposure to violence, gang activity, and criminal activity. The protective
    factors included that Gavin had “warm, supportive relationships with [his]
    parents and other adults.”

    20-11271                   Opinion of the Court                                21
    emphasized that, during Gavin’s incarceration in Illinois, Gavin
    was the victim of gang violence, was stabbed many times, and
    hospitalized.
    Gavin also offered the deposition testimony of Dr. Craig
    Haney, a social psychologist and professor of psychology. He
    testified about the effects of institutionalization19 on individuals
    generally, and on Gavin specifically. According to Haney,
    institutionalization causes individuals to “not be able to function
    adequately” in society because such individuals are accustomed to
    a heavily structured, regulated environment, where institutions tell
    them what to do, and once released, the individual has trouble
    initiating behavior, making plans, and dealing with the freedoms of
    society. Haney opined that because Gavin was only 22 and still in
    fundamental stages of development when he entered the Illinois
    prison system for the first murder, the effect of institutionalization
    on him was “relatively powerful” and undermined his ability to
    adjust positively to society once released. 20
    19
    Haney defined institutionalization as “the process of change that occurs in
    people when they are placed in institutional . . . settings.” Institutionalization
    is considered a “social phenomenon” and is not a recognized clinical diagnosis
    in the Diagnostic and Statistical Manual (DSM).
    20
    Haney reviewed Gavin’s prison records from the Illinois prison system.
    During Gavin’s 17 years in prison in Illinois, Gavin had only one major
    disciplinary write-up for a shank being found in his possession, and his other
    write-ups were for minor infractions, such as listening to his television too
    loudly. Gavin was transferred 12 times during the 17-year period, and Dr.
    Haney opined that each transfer increased Gavin’s risk of becoming
    USCA11 Case: 20-11271           Date Filed: 07/14/2022        Page: 22 of 53
    22                         Opinion of the Court                     20-11271
    Finally, Dr. Glen King testified as an expert witness in the
    area of clinical and forensic psychology on behalf of the State.
    Gavin reported to Dr. King that (1) he had no history of alcohol or
    substance abuse issues; (2) “his parents were loving, devoted and
    good parents”; (3) he denied being physically abused as a child—
    although when pressed he acknowledged that his father’s discipline
    “maybe bordered on that”; (4) his neighborhood “was relatively
    safe,” especially during the first 12 years of his life—so safe, the
    family left their door unlocked—but violence in the neighborhood
    increased when Gavin was a teenager;21 (5) he told Dr. King that
    there “wasn’t much gang violence” in the neighborhood and that
    “he was not particularly afraid” of his neighborhood; (6) he
    reported that his family was very close and denied being poor; and
    (7) while in the Illinois prison system, he earned his GED and took
    college courses and vocational training.
    Following the evidentiary hearing, the Alabama
    postconviction court denied Gavin’s Rule 32 ineffective-assistance
    claim on the merits. The Rule 32 court found that counsel was not
    “institutionalized.” However, Gavin reported that he requested to be
    transferred each of those 12 times because “it broke up the time for him, [and]
    made things go a lot faster.” The State’s expert testified that Gavin’s prison
    records from Illinois revealed that he became “what you might describe
    almost as a model prisoner and did extremely well.”
    21
    According to Dr. King, Gavin reported in his interview that “he was not
    aware of too much violence occurring until he was probably about 16 or 17
    when he reported that that was when the drugs started to get heavier in his
    neighborhood.”
    USCA11 Case: 20-11271       Date Filed: 07/14/2022    Page: 23 of 53
    20-11271               Opinion of the Court                       23
    deficient for failing to present additional mitigation evidence,
    concluding that it was Gavin’s and his family’s fault “for failing or
    refusing to cooperate with his trial attorneys and the mitigation
    specialists.” Further, the court noted that much of the mitigation
    information presented would have been unlikely to “humanize”
    Gavin because it would have portrayed him “as the product of a
    violent family from a violent, gang ridden, and drug infested
    Chicago ghetto where the Defendant had previously committed a
    murder. . . .”
    The Alabama Court of Criminal Appeals (“CCA”) affirmed
    the denial of Gavin’s petition. With regard to Gavin’s ineffective-
    assistance claim, the CCA, relying on Smith’s affidavit from the
    motion for new trial, emphasized that Smith hired Penland to assist
    with mitigation almost immediately after taking the case, and that
    the correspondence between Smith and Penland established that
    she could not complete her investigation because Gavin and his
    family were uncooperative. Based on these circumstances, the
    CCA held that “we are unable to say that the investigative steps
    taken by Gavin’s trial counsel were unreasonable, and the circuit
    court did not err in denying this claim.”
    As for prejudice, the CCA reweighed the mitigation
    evidence from the Rule 32 hearing against that presented at trial
    and determined that Gavin was not prejudiced by counsel’s failure
    to present this evidence. Specifically, the CCA reasoned as follows:
    The trial court found the existence of three
    aggravating circumstances: (1) that the capital offense
    USCA11 Case: 20-11271      Date Filed: 07/14/2022     Page: 24 of 53
    24                     Opinion of the Court                20-11271
    was committed while Gavin was under a sentence of
    imprisonment; (2) that Gavin had previously been
    convicted of another capital offense or a felony
    involving the use or threat of violence to the person;
    and (3) that the murder was committed during the
    course of a robbery in the first degree. Additionally,
    the trial court found that no statutory mitigating
    circumstances existed and that there were no
    nonstatutory mitigating circumstances.              The
    evidence presented at Gavin’s Rule 32 evidentiary
    hearing was to a great extent centered around Gavin’s
    childhood in Chicago and imprisonment and, as the
    circuit court noted, likely would have been given very
    little weight by the jury. Thus, we agree . . . that the
    admission of this evidence would not have changed
    the verdict in the penalty phase.
    Accordingly, Gavin has failed to establish that he was
    prejudiced by the alleged omission of the above
    mitigating evidence. We agree with the circuit court
    that this testimony would have been unlikely to have
    humanized Gavin with his jury, and the circuit court
    correctly denied this claim.
    As for Gavin’s juror misconduct claim, the CCA denied the
    claim on the merits, concluding that the claim was based on the
    admission of juror testimony, which would have been inadmissible
    under Alabama Rule of Evidence 606(b).

    D. Federal § 2254 Habeas Proceeding
    Following the denial of state postconviction relief, Gavin
    filed the underlying § 2254 federal habeas petition, which the
    district court granted in part and denied in part. The district court
    held that counsel’s performance related to the penalty phase was
    deficient and prejudicial under Strickland, and that the state court’s
    conclusion to the contrary was an objectively unreasonable
    application of Strickland. Gavin v. Dunn, 
    449 F. Supp. 3d 1174
    ,
    1245–49 (N.D. Ala. 2020).
    As to the question of performance, the district court
    concluded that “[c]ounsel were totally unprepared for the penalty
    phase.” 
    Id. at 1245
    . The court emphasized that “[c]ounsel’s lack of
    preparation [could not] be excused by the initial failure of Mr.
    Gavin and his family to cooperate with counsel or Ms. Penland,
    because Mr. Sturman was able to get mitigating evidence from
    [Gavin’s mother] prior to trial.” 
    Id.
     The court noted that, although
    it had “no insight into counsel’s decision not to elicit testimony
    concerning Mr. Gavin’s background from [his mother at trial],”
    counsel’s decision to not do so was “inexplicable.” 
    Id.
     at 1245–46.
    The district court also concluded that Sturman’s report “should
    have raised red flags” for counsel, and that “counsel’s failure to
    follow up on [the red flags] was deficient under Strickland.” 
    Id. at 1246
    . Accordingly, the court held that
    [t]rial counsel did not conduct an adequate
    background investigation, did not pursue all
    reasonably available mitigating evidence, and did not
    USCA11 Case: 20-11271      Date Filed: 07/14/2022     Page: 26 of 53
    26                     Opinion of the Court               20-11271
    make a reasonable effort to present the mitigating
    evidence they had. Mr. Gavin has clearly established
    that counsel were deficient under Strickland. Thus, it
    follows that the [CCA’s] finding to the contrary is
    objectively unreasonable.
    
    Id.
     at 1246–47.
    Turning to the question of prejudice, the district court
    explained that
    [i]f counsel had presented the evidence Mr. Gavin
    produced at the Rule 32 hearing, the jury would have
    heard evidence that Mr. Gavin’s parents’ families had
    histories of drug abuse, alcoholism, . . . and
    incarceration; Mr. Gavin’s siblings were gang
    members with histories of drug use, violence, and
    incarceration; Mr. Gavin’s father Willie, Sr., was
    physically abusive . . .; and that Mr. Gavin grew up in
    a gang-infested housing project in Chicago, living in
    overcrowded houses that were in poor condition,
    where he was surrounded by drug activity, crime,
    violence, and riots.
    
    Id.
     at 1247–48. The district court noted that the CCA determined
    that “this evidence would ‘likely have been given very little weight
    by the jury,’” but the district court disagreed with that finding,
    citing Supreme Court cases and cases from this Court in which
    prejudice was found due to the omission of similar mitigating
    evidence. 
    Id.
     at 1248–49. Accordingly, the district court held that
    because of the value placed on this type of mitigation evidence in
    USCA11 Case: 20-11271       Date Filed: 07/14/2022    Page: 27 of 53
    20-11271               Opinion of the Court                       27
    other cases, the CCA’s “contrary finding is an unreasonable
    application of Strickland.” 
    Id. at 1249
    .
    With regard to the juror misconduct claim, the district court
    held that the CCA’s denial of Gavin’s premature jury deliberation
    claim was neither contrary to, nor an unreasonable application of,
    clearly established federal law because Gavin failed to show that
    extrinsic evidence was injected into the jury deliberations and the
    evidence Gavin offered was “nothing more than prohibited
    testimony about the debate and deliberations of the jury.” 
    Id.
     at
    1203–06. The state of Alabama’s appeal and Gavin’s cross-appeal
    followed.
    II.    Standard of Review
    We review the district court’s ruling on a § 2254 habeas
    petition de novo. Morrow v. Warden, Ga. Diagnostic Prison, 
    886 F.3d 1138
    , 1146 (11th Cir. 2018). Yet the Antiterrorism and
    Effective Death Penalty Act of 1996 (“AEDPA”) also governs this
    appeal, which establishes a “highly deferential standard for
    evaluating state-court rulings, [and] demands that state-court
    decisions be given the benefit of the doubt.” Cullen v. Pinholster,
    
    563 U.S. 170
    , 181 (2011) (quoting Woodford v. Viscotti, 
    537 U.S. 19
    , 24 (2002) (per curiam)). Thus, under AEDPA, a federal court’s
    review of a final state habeas decision is greatly circumscribed, and
    a federal habeas court cannot grant a state petitioner habeas relief
    on any claim that was adjudicated on the merits in state court
    unless the state court’s adjudication of the claim:
    USCA11 Case: 20-11271         Date Filed: 07/14/2022   Page: 28 of 53
    28                     Opinion of the Court                20-11271
    (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)(1)–(2).
    “[C]learly established Federal law” means “the holdings, as
    opposed to the dicta, of [the Supreme] Court’s decisions as of the
    time of the relevant state-court decision.” Williams v. Taylor, 
    529 U.S. 362
    , 412 (2000).
    For a state-court decision to be “contrary to” clearly
    established federal law, the state court must have “applie[d] a rule
    different from the governing law set forth in [Supreme Court]
    cases, or if it decides a case differently than [the Supreme Court]
    ha[s] done on a set of materially indistinguishable facts.” Bell v.
    Cone, 
    535 U.S. 685
    , 694 (2002).
    An “unreasonable application” of federal law occurs “if the
    state court correctly identifies the governing legal principle from
    [the Supreme Court’s] decisions but unreasonably applies it to the
    facts of the particular case.” 
    Id.
     “[A]n unreasonable application of
    federal law is different from an incorrect application of federal
    law.” Williams, 
    529 U.S. at 410

    federal habeas court may not issue the writ simply because that
    court concludes in its independent judgment that the relevant

    state-court decision applied clearly established federal law
    erroneously or incorrectly.’” Renico v. Lett, 
    559 U.S. 766
    , 773
    (2010) (quoting Williams, 
    529 U.S. at 411
    ). Rather, the state court’s
    application of federal law “must be ‘objectively unreasonable.’
    This distinction creates ‘a substantially higher threshold’ for
    obtaining relief than de novo review.”

    572 U.S. 415
    , 419 (2014) (explaining that, for
    purposes of § 2254(d)(1), the state court’s application of clearly
    established federal law must be “objectively unreasonable, not
    merely wrong; even clear error will not suffice” (quotation
    omitted)). “[W]hen the last state court to decide a prisoner’s
    federal claim explains its decision on the merits in a reasoned
    opinion . . . a federal habeas court simply reviews the specific
    reasons given by the state court and defers to those reasons if they
    are reasonable.” Wilson v. Sellers, 
    138 S. Ct. 1188
    , 1192 (2018).
    A state court’s decision is reasonable “so long as ‘fairminded

    , 101 (2011) (quoting
    Yarborough v. Alvarado, 
    541 U.S. 652
    , 664 (2004)). “[E]ven a strong
    case for relief does not mean the state court’s contrary conclusion
    was unreasonable.” Id. at 102. Rather, a prisoner 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.” Id. at 103.

    bears “the burden of rebutting the presumption of correctness by
    clear and convincing evidence.” 
    28 U.S.C. § 2254
    (e)(1). With these
    principles in mind, we turn to the claims at issue in this appeal.
    III.   Discussion
    A. Ineffective Assistance During the Penalty Phase
    Alabama argues that the state court’s determinations that
    counsel’s mitigation efforts were reasonable and that Gavin did not
    suffer any prejudice was not an objectively unreasonable
    application of Strickland, and that the district court erred in not
    deferring to the state court’s decision as required by § 2254.
    A petitioner alleging that he received ineffective assistance
    of counsel in violation of the Sixth Amendment must establish two
    elements. Strickland v. Washington, 
    466 U.S. 668
    , 687 (1984).
    “First, the defendant must show that counsel’s performance was
    deficient.” 
    Id.
     Review of counsel’s actions is “highly deferential”
    and “a court must indulge a strong presumption that counsel’s
    conduct falls within the wide range of reasonable professional
    assistance.” 
    Id. at 689
    . Additionally, “every effort [must] be made
    to eliminate the distorting effects of hindsight, to reconstruct the
    circumstances of counsel’s challenged conduct, and to evaluate the
    conduct from counsel’s perspective at the time.” 
    Id.
     In other
    words, the petitioner must show “that counsel made errors so
    serious that counsel was not functioning as the ‘counsel’
    guaranteed the defendant by the Sixth Amendment.” 
    Id. at 687
    .
    USCA11 Case: 20-11271       Date Filed: 07/14/2022     Page: 31 of 53
    20-11271               Opinion of the Court                        31
    “Second, the defendant must show that the deficient
    performance prejudiced the defense.” 
    Id.
     Prejudice occurs when
    there is a reasonable probability that “but for counsel’s
    unprofessional errors, the result of the proceeding would have
    been different.” 
    Id. at 694
    . In the capital sentence context, “the
    question is whether there is a reasonable probability that, absent
    the errors, the sentencer—including an appellate court, to the
    extent it independently reweighs evidence—would have
    concluded that the balance of aggravating and mitigating
    circumstances did not warrant death.” 
    Id. at 695
    . “The likelihood
    of a different result must be substantial, not just conceivable.”
    Harrington, 
    562 U.S. at 112
    . In determining whether there is a
    reasonable probability of a different result, a court must “consider
    ‘the totality of the available mitigation evidence—both that
    adduced at trial, and the evidence adduced in the habeas
    proceeding’—and ‘reweig[h] it against the evidence in
    aggravation.’” Porter v. McCollum, 
    558 U.S. 30
    , 41 (2009) (quoting
    Williams, 
    529 U.S. at
    397–98).
    “[B]ecause the Strickland standard is a general standard, a
    state court has even more latitude to reasonably determine that a
    defendant has not satisfied that standard.” Knowles v. Mirzayance,
    
    556 U.S. 111
    , 123 (2009); see also Renico, 
    559 U.S. at 776
     (“Because
    AEDPA authorizes federal courts to grant relief only when state
    courts act unreasonably, it follows that ‘[t]he more general the rule’
    at issue—and thus the greater the potential for reasoned
    disagreement among fair-minded judges—‘the more leeway [state]
    USCA11 Case: 20-11271       Date Filed: 07/14/2022       Page: 32 of 53
    32                     Opinion of the Court                   20-11271
    courts have in reaching outcomes in case-by-case determinations.’”
    (quoting Yarborough, 
    541 U.S. at 664
    )).
    Importantly, “whether defense counsel’s performance fell
    below Strickland’s standard” is not the question before a federal
    habeas court reviewing a state court’s decision under § 2254.
    Harrington, 
    562 U.S. at 101
    .
    Were that the inquiry, the analysis would be no
    different than if, for example, this Court were
    adjudicating a Strickland claim on direct review of a
    criminal conviction in a United States district court.
    Under AEDPA, though, it is a necessary premise that
    the two questions are different . . . [for] [a] state court
    must be granted a deference and latitude that are not
    in operation when the case involves review under the
    Strickland standard itself.
    
    Id.
     Accordingly, where, as here, Ҥ 2254(d) applies, the question is
    not whether counsel’s actions were reasonable. The question is
    whether there is any reasonable argument that counsel satisfied
    Strickland’s deferential standard.” Id. at 105 (emphasis added).
    Consequently, “[f]ederal habeas courts must guard against the
    danger of equating unreasonableness under Strickland with
    unreasonableness under § 2254(d).” Id.
    (i) Deficient Performance
    With regard to the deficient performance prong, the CCA
    determined that Smith hired Penland to assist with mitigation
    almost immediately after taking the case, and that the
    USCA11 Case: 20-11271       Date Filed: 07/14/2022     Page: 33 of 53
    20-11271               Opinion of the Court                        33
    correspondence between Smith and Penland established that she
    could not complete her investigation because Gavin and his family
    were uncooperative. Based on these circumstances, the CCA held
    that “we are unable to say that the investigative steps taken by
    Gavin’s trial counsel were unreasonable, and the circuit court did
    not err in denying this claim.” The district court, however,
    concluded that the CCA’s finding was an objectively unreasonable
    application of Strickland and its progeny, and that Gavin had
    established deficient performance. Gavin, 449 F. Supp. 3d at 1245–
    47.
    As explained below, the district court erred in its
    determination. The Supreme Court has clearly, and repeatedly,
    held that counsel’s actions must be afforded a presumption of
    adequacy and “that the burden to ‘show that counsel’s
    performance was deficient’ rests squarely on the defendant.” Burt
    v. Titlow, 
    571 U.S. 12
    , 22 (2013) (quoting Strickland, 
    466 U.S. at 687
    ). Thus, Gavin must have come forward with sufficient
    evidence to overcome the presumption, and “the absence of
    evidence cannot overcome the ‘strong presumption that counsel’s
    conduct [fell] within the wide range of reasonable professional
    assistance.’” Id. at 23 (alterations in original) (quoting Strickland,
    
    466 U.S. at 689
    ). “In fact, even if there is reason to think that
    counsel’s conduct was far from exemplary, a court still may not
    grant relief if [t]he record does not reveal that counsel took an
    approach that no competent lawyer would have chosen.” Dunn v.
    Reeves, 
    141 S. Ct. 2405
    , 2410 (2021) (quotation omitted). Gavin has
    USCA11 Case: 20-11271        Date Filed: 07/14/2022      Page: 34 of 53
    34                      Opinion of the Court                  20-11271
    not shown that the state court’s determination that counsel’s
    performance was not unreasonable was contrary to, or an
    unreasonable application of, Strickland.
    In this case, there is an absence of evidence regarding the full
    picture of counsel’s investigation in preparation for the penalty
    phase. As an initial matter, we do not have the benefit of counsel’s
    testimony from the evidentiary hearing—Smith was deceased at
    the time of the Rule 32 hearing and Gavin did not call co-counsel
    Ufford to testify. We agree that counsel’s testimony is not always
    necessary. See Reeves, 141 S. Ct. at 2411–13 (explaining that the
    defendant’s failure to call his attorneys to testify can be, but is not
    per se, fatal to an ineffective-assistance claim). The petitioner can
    establish counsel’s deficient performance in other ways. And in
    Gavin’s case, he submitted declarations from both counsel that
    they had submitted in connection with Gavin’s motion for a new
    trial in 2000, affidavits from various individuals, and testimony
    from several witnesses at the evidentiary hearing, including the
    mitigation specialist that his counsel had hired to help prepare for
    the penalty phase.
    But the record developed by Gavin does not show that the
    state court’s determination that his counsel’s performance was not
    unreasonable “was so lacking in justification that there was an error
    well understood and comprehended in existing law beyond any
    possibility for fairminded disagreement.” Harrington, 
    562 U.S. at 103
    . Rather, the record shows that Gavin’s counsel did, in fact,
    prepare for the penalty phase. Smith hired mitigation specialist
    USCA11 Case: 20-11271         Date Filed: 07/14/2022       Page: 35 of 53
    20-11271                 Opinion of the Court                           35
    Penland shortly after his appointment to Gavin’s case to help
    prepare for mitigation. Gavin and his family were consistently
    uncooperative leading up to the penalty phase. Penland admitted
    that Smith engaged in his own independent investigation, and she
    had no knowledge of the details of his investigation. The record
    corroborates that Smith conducted his own independent
    investigation. For instance, he hired Dennis Scott, a private
    investigator; requested and obtained additional funding for Scott’s
    services; and had Scott sit at counsel’s table throughout the voir
    dire and trial proceedings—a clear indicator that Scott played a
    pivotal role in the defense’s preparation. Yet, the record contains
    no information related to Scott’s investigation or counsel Smith’s
    independent investigative efforts. In other words, the record is
    incomplete concerning Gavin’s counsel’s investigation.
    “Strickland specifically commands that a court must indulge
    [the] strong presumption that counsel made all significant decisions
    in the exercise of reasonable professional judgment.” Pinholster,
    
    563 U.S. at 196
     (quotation omitted). An incomplete or ambiguous
    record concerning counsel’s performance—like the record here—
    is insufficient to overcome the presumption of reasonable
    performance.22 Callahan v. Campbell, 
    427 F.3d 897
    , 933 (11th Cir.
    22
    Contrary to Gavin’s argument in his brief and at oral argument, we do not
    hold that the record must contain testimony from counsel to establish
    deficient performance nor do we hold that there is a deceased-trial-counsel
    exception to Strickland. We merely hold, consistent with Supreme Court
    precedent, that (1) courts are required to presume that counsel acted
    USCA11 Case: 20-11271            Date Filed: 07/14/2022         Page: 36 of 53
    36                         Opinion of the Court                       20-11271
    2005) (“Because [counsel] passed away before the Rule 32 hearing,
    we have no evidence of what he did to prepare for the penalty
    phase of [the defendant’s] trial. In a situation like this, we will
    presume the attorney did what he should have done, and that he
    exercised reasonable professional judgment.” (quotation and
    footnote omitted)). Accordingly, the state court’s determination
    that, given the circumstances here, it could not conclude “that the
    investigative steps taken by Gavin’s trial counsel were
    unreasonable” was not an objectively unreasonable application of
    reasonably, (2) the petitioner bears the burden of overcoming that
    presumption, and (3) an incomplete or ambiguous record is insufficient to
    overcome the presumption of reasonableness to which counsel is entitled.
    Although Smith was deceased at the time of Gavin’s Rule 32 evidentiary
    hearing, there were other ways in which Gavin could have presented a
    complete picture of counsel’s performance. For instance, Gavin could have
    called co-counsel Ufford, but he did not. Gavin also could have presented
    evidence related to the efforts undertaken by private investigator Scott—who
    it is clear from the record played a significant role in Gavin’s defense—but he
    did not. Or Gavin could have presented testimony or affidavits from his
    mother or any of his eleven siblings detailing what interactions, if any, they
    had with Gavin’s trial counsel, Penland, or Sturman, but again he did not. In
    short, despite Smith’s unavailability, there were numerous other ways in
    which Gavin could have met his burden of proving the full extent—or lack
    thereof—of counsel’s investigation, but he failed to do so. We note that the
    aforementioned evidence provides just a few examples of the types of
    evidence a petitioner can present in support of his ineffective-assistance claim;
    it is not meant to be a comprehensive list. Nor do we mean to suggest that if
    a petitioner produces all of this evidence he will necessarily prevail.

    Strickland, and the district court erred in holding otherwise.23
    Gavin, 449 F. Supp. 3d at 1244.
    We note that, although the district court cited AEDPA and
    its deferential principles in its opinion, it did not follow them when
    considering Gavin’s ineffective-assistance claim. Rather than
    evaluating whether the CCA’s determination that counsel’s
    performance was not deficient was contrary to, or an objectively
    unreasonable application of, Strickland—as required by the text of
    23
    Gavin maintains that we have “relied on similar facts” as those present in his
    case to find deficient performance in Evans v. Sec’y, Dep’t of Corr. (“Evans
    I”), 
    681 F.3d 1241
     (11th Cir. 2012); Maples v. Comm’r, Ala. Dep’t of Corr., 729
    F. App’x 817 (11th Cir. 2018); Cunningham v. Zant, 
    928 F.2d 1006
     (11th Cir.
    1991); and Blake v. Kemp, 
    758 F.2d 523
     (11th Cir. 1985). His reliance on those
    cases is misplaced. The Evans decision he cites was vacated upon our decision
    to grant rehearing en banc, and on rehearing we did not address the deficiency
    prong. See Evans v. Sec’y, Dep’t of Corr. (“Evans II”), 
    703 F.3d 1316
    , 1325–26
    (11th Cir. 2013) (en banc). Maples is an unpublished, non-binding authority
    that is fully distinguishable because the deferential principles of AEDPA did
    not apply as the state court based its factual conclusions on the wrong Rule 32
    petition and “conducted a splintered and fragmented prejudice analysis”
    which failed to consider the combined prejudicial effects of all of the alleged
    errors. 729 F. App’x at 821–23. And finally, both Cunningham and Blake are
    pre-AEDPA cases involving plenary review of ineffective-assistance claims,
    and not the deferential framework of AEDPA that we are required to follow
    now. See Cunningham, 
    928 F.2d at 1016

    38                      Opinion of the Court                  20-11271
    § 2254(d)—the district court turned the inquiry on its head and
    determined that because in its view “Gavin clearly established that
    counsel were deficient under Strickland,” it followed necessarily
    that the CCA’s “finding to the contrary [was] objectively
    unreasonable.” Gavin, 449 F. Supp. 3d at 1246–47. In short, the
    district court failed to “guard against the danger of equating
    unreasonableness under Strickland with unreasonableness under
    § 2254(d),” and fell into the trap the Supreme Court warned of in
    Harrington. See Harrington, 
    562 U.S. at 105
    .
    To be clear, the Strickland inquiry and the § 2254(d) inquiry
    are distinct inquiries. Id. at 101. For purposes of § 2254(d), the state
    court’s application of clearly established federal law “must be
    objectively unreasonable, not merely wrong; even clear error will
    not suffice.” White, 572 U.S. at 419 (quotation omitted); Renico,
    
    559 U.S. at 773
    ; see also Hosley v. Warden, Ga. Diagnostic Prison,
    
    694 F.3d 1230
    , 1257 (11th Cir. 2012) (explaining that AEDPA
    “preserves authority to issue the writ in cases where there is no
    possibility fairminded jurists could disagree that the state court’s
    decision conflicts with th[e] [Supreme] Court’s precedents. It goes
    no farther.” (quotation omitted)). The district court erred in
    examining anew whether counsel’s performance fell below
    Strickland ’s reasonableness standard and then concluding that
    because—in the district court’s view—counsel’s performance fell
    below that standard, the state court’s determination to the contrary
    was an objectively unreasonable application of Strickland.

    (ii) Prejudice
    Gavin also failed to demonstrate that the state court’s
    determination that he did not satisfy the prejudice prong was an
    unreasonable application of Strickland. The district court
    unreasonably rejected the CCA’s finding that the mitigation
    evidence would have been given little weight by the jury, based
    solely on the fact that the Supreme Court had placed value on
    similar types of mitigation evidence in other cases. As explained
    previously, in assessing prejudice under Strickland in a capital case,
    “the question is whether there is a reasonable probability that,
    absent the errors, the sentencer—including an appellate court, to
    the extent it independently reweighs evidence—would have
    concluded that the balance of aggravating and mitigating
    circumstances did not warrant death.”24 Strickland, 
    466 U.S. at 695
    .
    24
    Gavin’s argument that the state court’s decision should not receive AEDPA
    deference because it applied the wrong standard when assessing prejudice
    lacks merit. In support, he points to the CCA’s statement that the omitted
    mitigation evidence would not have changed the verdict and the fact that the
    CCA did not mention reasonable probability of a different outcome in its
    holding. Gavin’s argument is incorrect. The CCA explained and applied the
    proper prejudice analysis, consistent with the standard in Strickland. For
    instance, the CCA explained that “[w]hen claims of ineffective assistance of
    counsel involve the penalty phase of a capital murder trial the focus is on
    whether the sentencer would have concluded that the balance of aggravating
    and mitigating circumstances did not warrant death,” which is the test set
    forth by the Supreme Court. Strickland, 
    466 U.S. at 695
    . It then applied that
    test, reweighing the totality of the mitigating evidence against the aggravating
    circumstances in Gavin’s case. Further confirmation that the CCA applied the
    Strickland prejudice standard is that the CCA cited Wiggins v. Smith, 539 U.S.

    Given that the jury recommended a sentence of death by the
    narrowest possible vote under Alabama law, 10 to 2, Gavin “need
    establish only ‘a reasonable probability that at least one juror
    would have struck a different balance’ between life and death.”
    Jenkins v. Comm’r, Ala. Dep’t of Corr., 
    963 F.3d 1248
    , 1270 (11th
    Cir. 2020) (quoting Wiggins, 539 U.S. at 537); see also n.7, supra
    (discussing Alabama’s capital sentencing scheme and that a
    recommendation of death requires the vote of at least ten jurors).
    It was reasonable for the CCA to conclude that counsel’s
    failure to present the mitigation evidence in question was not
    prejudicial. In assessing the reasonable probability of a different
    result, the state court’s task was to determine whether there was a
    substantial likelihood that the outcome would have been different
    by weighing the aggravating evidence and totality of the mitigating
    evidence—both that adduced at trial and during the habeas
    proceeding. Porter, 
    558 U.S. at 41
    ; see also Harrington, 
    562 U.S. at 112
     (“The likelihood of a different result must be substantial, not
    just conceivable.”). At Gavin’s sentencing, the trial court
    concluded that there were no statutory mitigating factors or non-
    statutory mitigating circumstances present. Thus, the question for
    the CCA was whether the non-statutory mitigation evidence
    presented in the postconviction proceedings would have
    outweighed the following aggravating factors: (1) that Gavin was
    510 (2003), and its own decision in Washington v. State, 
    95 So. 3d 26
     (Ala. Ct.
    Crim. App. 2012), both of which applied Strickland ’s standards for assessing
    prejudice.

    20-11271                  Opinion of the Court                              41
    previously convicted of another felony involving the use or threat
    of violence to a person (his prior murder conviction); (2) that Gavin
    committed the murder during the commission of a robbery; and
    (3) that he committed the murder while under a sentence of
    imprisonment for another crime.
    At his Rule 32 hearing before the state postconviction court,
    Gavin presented non-statutory mitigation evidence that largely
    centered on his childhood and the effects of his previous
    imprisonment in Illinois. This evidence established that he grew
    up “in the projects in Chicago,” and he was exposed to gang
    violence and drug activity in the neighborhood and from his
    siblings. His father was a strong disciplinarian and whipped the
    children, which Gavin stated may have in hindsight amounted to
    physical abuse, and there was some testimony that his father
    abused his mother. 25 Nevertheless, there was also evidence that
    25
    Gavin argues that the state court unreasonably discounted the evidence of
    his childhood abuse because of his age and its remoteness in time to the crimes
    in contravention of Porter. Gavin misinterprets Porter, in which the Supreme
    Court held that it was “unreasonable to discount to irrelevance the evidence
    of [the defendant’s] abusive childhood” even though he was 54 years old at the
    time of the trial. 
    558 U.S. at 37, 43
    . Contrary to Gavin’s argument, Porter did
    not announce a broad principle that courts may not consider age of the
    defendant as a factor in assessing the weight to give mitigation evidence. And,
    in Gavin’s case, the CCA did not discount the minimal evidence of childhood
    abuse to “irrelevance” but instead determined it was entitled to little weight,
    which was not contrary to, or an unreasonable application of, clearly
    established federal law.

    42                         Opinion of the Court                       20-11271
    his family was close, loving, and supportive. And the testimony
    concerning the effects of his previous imprisonment for murder
    was conflicting at best. For instance, Gavin’s expert witness
    testified that Gavin’s prior incarceration undermined his ability to
    adjust positively to society; that he was transferred twelve times
    due to safety concerns, with each transfer increasing the risk of
    institutionalization; and that the Illinois prison system failed Gavin
    by not offering him various services and vocational training. On
    the other hand, the State’s expert testified that institutionalization
    is not a scientifically recognized condition and that Gavin’s prison
    records indicated he was a model prisoner; that Gavin reported that
    he requested the transfers to break “up the time”; and that Gavin
    received his GED and took various college and vocational courses
    Moreover, the mitigating evidence in Porter was significantly more
    compelling than that presented in Gavin’s case. For instance, in Porter, the
    jury never heard about (1) his “heroic military service in two of the most
    critical—and horrific—battles of the Korean War”; (2) his mental health
    struggles following the war; (3) his history of childhood abuse—including that
    his father beat his mother routinely (once so severely that she had to go to the
    hospital and suffered a miscarriage) and also was violent with the children,
    especially Porter, and that his father shot a gun at him for coming home late;
    (4) that Porter was in special education classes and left school at the age of 12
    or 13; and (5) that he suffered from brain damage that could result in
    “impulsive, violent behavior.” 
    558 U.S. at
    33–37, 41. The Supreme Court
    reasoned that had the jury heard this information there was a reasonable
    probability that the jury and the sentencing judge would have struck a
    different balance, particularly because as to one of the murders there was one
    aggravating factor—that the murder was committed in a cold, calculated, and
    premeditated manner—that tipped the scales in favor of death.
    USCA11 Case: 20-11271       Date Filed: 07/14/2022     Page: 43 of 53
    20-11271               Opinion of the Court                        43
    while in prison. The Rule 32 postconviction court concluded that
    the mitigation evidence in question would have been unlikely to
    “humanize” Gavin because it would have portrayed him “as the
    product of a violent family from a violent, gang ridden, and drug
    infested Chicago ghetto where the Defendant had previously
    committed a murder. . . . [and] would have necessarily emphasized
    [Gavin’s] violent history.” The CCA agreed that the admission of
    this evidence “would have been unlikely to have humanized Gavin
    with [the] jury” and would have been entitled to little weight. In
    other words, the non-statutory mitigation evidence Gavin
    presented could have been a double-edged sword.
    It was not unreasonable for the state court to conclude that
    there was not a substantial likelihood that the jury would have
    concluded that the non-statutory mitigation evidence—which was
    of limited value and could have been a double-edged sword—
    would have outweighed the three significant statutory aggravating
    factors present in this case. See, e.g., Jenkins, 963 F.3d at 1271–73
    (holding that state court did not unreasonably apply Strickland
    when it concluded that similar mitigating evidence—some of
    which was “a double-edged sword”—did not outweigh the
    significant aggravating factors); Jones v. Sec’y, Fla. Dep’t of Corr.,
    
    834 F.3d 1299
    , 1312–1315 (11th Cir. 2016) (holding that state court’s
    determination that the petitioner failed to demonstrate prejudice
    was reasonable where the mitigating evidence was of limited value
    and there were significant aggravating factors); Evans v. Sec’y,
    Dep’t of Corr., 
    703 F.3d 1316
    , 1327 (11th Cir. 2013) (en banc)
    USCA11 Case: 20-11271       Date Filed: 07/14/2022    Page: 44 of 53
    44                     Opinion of the Court                20-11271
    (holding that state court reasonably applied Strickland when it
    concluded that the petitioner failed to establish prejudice where the
    mitigation evidence was a double-edged sword). Gavin failed to
    show that the state court’s determination that he failed to satisfy
    Strickland ’s prejudice prong “was so lacking in justification that
    there was an error well understood and comprehended in existing
    law beyond any possibility for fairminded disagreement.”
    Harrington, 
    562 U.S. at 103
    .
    In concluding that the state court’s prejudice determination
    was based on an unreasonable application of Strickland, the district
    court simply analogized Gavin’s case to cases in which the
    Supreme Court and this Court had found similar types of
    mitigation evidence sufficient to justify relief under Strickland,
    without accounting for any procedural or factual differences
    between Gavin’s case and those cases. But the prejudice inquiry
    under Strickland involves a case-by-case inquiry—simply because
    prejudice was found after considering similar omitted mitigating
    evidence in one case is not dispositive of whether prejudice
    necessarily exists in another.
    We also note that in several of the cases on which Gavin
    relied—Wiggins, Rompilla, and Williams—AEPDA deference did
    not apply to the prejudice prong. See Wiggins, 539 U.S. at 534
    (explaining that because the state court never addressed the
    prejudice prong, the Supreme Court’s “review [was] not
    circumscribed by a state court conclusion with respect to
    prejudice”); Rompilla v. Beard, 
    545 U.S. 374
    , 390 (2005) (reviewing
    USCA11 Case: 20-11271        Date Filed: 07/14/2022     Page: 45 of 53
    20-11271                Opinion of the Court                        45
    the prejudice prong de novo because the state court “never reached
    the issue of prejudice”); Williams, 
    529 U.S. at 391, 395, 398
    ; see also
    Pinholster, 
    563 U.S. at 202
     (explaining that it “did not apply AEDPA
    deference to the question of prejudice in [Williams and
    Rompilla]”). Thus, as the Supreme Court has cautioned, because
    it “did not apply AEDPA deference to the question of prejudice in
    those cases,” they “offer no guidance with respect to whether a
    state court has unreasonably determined that prejudice is
    lacking”—which is the question we must answer in this case.
    Pinholster, 
    563 U.S. at 202
     (emphasis in original).
    Furthermore, the mitigation evidence in Wiggins was far
    more compelling than that presented in Gavin’s case. For instance,
    the omitted mitigation evidence in Wiggins indicated that
    Wiggins’s mother was an alcoholic who frequently left the children
    at home alone for days, forcing them to beg for food, eat paint chips
    and garbage; Wiggins’s mother was abusive and beat the children;
    she also had sex with men in the bed next to her children while they
    slept; Wiggins was placed in foster care where he suffered physical
    abuse, sexual molestation, and rape; Wiggins ran away from his
    foster home at 16 and was homeless living on the streets; and he
    had diminished mental capacity. 539 U.S. at 516–17, 535. The
    Supreme Court emphasized on de novo review that there was an
    absence of aggravating factors in Wiggins’s background, and thus,
    there was a reasonable probability that, if the jury had heard all of
    this compelling mitigation evidence, it would have returned a
    different sentence. Id. at 537–38. Unlike Wiggins, the mitigation
    USCA11 Case: 20-11271       Date Filed: 07/14/2022     Page: 46 of 53
    46                      Opinion of the Court                20-11271
    evidence in Gavin’s case is far less compelling, and he has three
    significant aggravating statutory factors.
    Similarly, the mitigation evidence uncovered in Rompilla—
    that Rompilla grew up in a very abusive environment (his mother
    drank during the pregnancy, his parents fought each other
    violently, his father beat his mother, his mother stabbed his father
    on at least one occasion, his father beat Rompilla with hands, fists,
    leather straps, belts, and sticks, there were “no expressions of
    parental love, affection or approval,” his father locked Rompilla
    and a sibling in a small wire dog pen that was filthy and filled with
    dog excrement); Rompilla was not allowed to have friends or talk
    on the phone; his childhood home had no heat or indoor plumbing;
    he and his siblings were not given appropriate clothing; that
    Rompilla had alcohol issues, schizophrenia and other disorders;
    and that “Rompilla’s IQ was in the mentally retarded range”—was
    much more powerful than the mitigation evidence present in
    Gavin’s case. 
    545 U.S. at
    391–93.
    In short, the balance of aggravating and mitigating factors is
    significantly different in Gavin’s case than in the precedents he
    cites. And no Supreme Court precedent applying AEDPA to state-
    court prejudice determinations compels a different result. We
    conclude that the CCA’s determination that Gavin failed to
    establish prejudice “was not so obviously wrong as to be beyond
    any possibility of fairminded disagreement” and the district court
    “exceeded its authority” in rejecting the state court’s
    determination. Shinn v. Kayer, 
    141 S. Ct. 517
    , 526 (2020)

    (quotation omitted). Accordingly, we reverse the district court’s
    decision.
    B. Juror Misconduct
    In his cross-appeal, Gavin argues that we should affirm the
    district court’s decision granting him a new penalty phase because
    the jury conducted premature penalty-phase deliberations, in
    violation of his Sixth and Fourteenth Amendment right to a fair
    trial by an impartial jury. Gavin asserts that the jury voted 10-2 to
    sentence him to death after the guilt phase but before the penalty
    phase. In support of this claim, Gavin argued in his habeas petition
    that the jury foreman informed postconviction counsel that, during
    the guilt phase deliberations, one of the jurors stated that “if [they]
    thought that he would vote differently because he and [Gavin]
    were both black, he wanted them to know that he was going to
    vote guilty and in favor of the death penalty.” Each of the jurors
    then wrote down their votes on a piece of paper for both guilt and
    innocence—the vote was unanimous in favor of guilt and 10 to 2
    in favor of death (which was the same vote following the penalty
    phase).
    The CCA denied this claim, concluding that it was based on
    inadmissible juror testimony about the internal deliberative
    process, citing Alabama Rule of Evidence 606(b). The district court
    denied federal habeas relief on this claim, concluding that the
    CCA’s decision was not contrary to, or an unreasonable application
    of, federal law. We agree.
    USCA11 Case: 20-11271        Date Filed: 07/14/2022     Page: 48 of 53
    48                      Opinion of the Court                 20-11271
    The Sixth and Fourteenth Amendments guarantee every
    criminal defendant the right to a fair trial by an impartial jury. Neb.
    Press Ass’n v. Stuart, 
    427 U.S. 539
    , 551 (1976). Thus, the Supreme
    Court has held that a juror who will automatically vote for the
    death penalty in every case regardless of “the facts or the trial
    court’s instructions of law” may be challenged for cause, and, if
    “one such juror is empaneled and the death sentence is imposed,
    the State is disentitled to execute the sentence.” Morgan v. Illinois,
    
    504 U.S. 719
    , 726, 729 (1992). Gavin argues that in his case “ten
    jurors” violated Morgan. However, Gavin’s case does not involve
    the type of juror at issue in Morgan—one who would
    automatically vote for the death penalty regardless of the evidence
    or the jury instructions. The jury’s premature penalty phase vote
    did not reflect any agreement or statement among the jurors that
    no matter what the penalty phase evidence showed that they
    would automatically vote for the death penalty. Thus, to the
    extent that Gavin relies on Morgan, it does not help him.
    Rather, the gravamen of Gavin’s claim is that an irregularity
    occurred during the juror deliberations—the jurors engaged in
    premature deliberations before the penalty phase—that violated
    his constitutional right to a fair trial. Gavin, who bears the burden
    of proving his claim, seeks to present evidence from the jury
    foreman in support of this claim. Alabama Rule of Evidence 606(b)
    (the no-impeachment rule) provides that “a juror may not testify
    in impeachment of the verdict . . . as to any matter or statement
    occurring during the course of the jury’s deliberations or to the
    USCA11 Case: 20-11271           Date Filed: 07/14/2022        Page: 49 of 53
    20-11271                  Opinion of the Court                              49
    effect of anything upon that or any other juror’s mind or emotions
    as influencing the” juror’s decision. Ala. Evid. R. 606(b). “Nor may
    a juror’s affidavit or evidence of any statement by the juror
    concerning a matter about which the juror would be precluded
    from testifying be received for these purposes.” 
    Id.
    However, the rule provides that “a juror may testify on the
    question [of] whether extraneous prejudicial information was
    properly brought to the jury’s attention or whether any outside
    influence was improperly brought to bear upon any juror.” Id.26
    Additionally, the Supreme Court has held that the no-
    impeachment rule must yield to juror testimony about racial
    animus in jury deliberations. See Pena-Rodriguez v. Colorado, 
    137 S. Ct. 855
    , 869 (2017) (analyzing Fed. R. Evid. 606(b)). 27 However,
    outside of these narrow exceptions, the Supreme Court has
    rejected attempts to circumvent the no-impeachment rule
    embodied in Federal Rule 606(b) (and by extension its state
    26
    Alabama Rule 606(b) is virtually identical to its federal counterpart Federal
    Rule of Evidence 606(b), which also provides that a juror may testify to
    extraneous prejudicial information or outside influences on jury. See Fed. R.
    Evid. 606(b).
    27
    We acknowledge that Pena-Rodriguez was decided after the CCA issued its
    decision in 2014, and it is not retroactively applicable to cases on collateral
    review. Tharpe v. Warden, 
    898 F.3d 1342
    , 1346 (11th Cir. 2018). And Gavin
    does not argue that Pena-Rodriguez affords him any relief. Nevertheless, we
    cite Pena-Rodriguez simply to acknowledge the existence of a second type of
    exception that the Supreme Court has recognized to the no-impeachment
    rule.

    counterparts). See Tanner v. United States, 
    483 U.S. 107
    , 126–27
    (1987) (holding that Federal Rule of Evidence 606(b) prohibited
    inquiry into alleged juror intoxication during deliberations and that
    other procedural safeguards in the trial process protected the
    defendant’s Sixth Amendment right to a fair trial); Warger v.
    Shauers, 
    574 U.S. 40
    , 44–48 (2014) (holding that federal Rule 606(b)
    prohibited introduction of evidence that a juror lied during voir
    dire). The Supreme Court emphasized the importance of Rule
    606(b) to ensuring “frankness and freedom of discussion” by jurors
    during deliberation, which would be destroyed if attorneys could
    later use juror testimony to attack the verdict. Tanner, 
    483 U.S. at 120, 127
    . The Court also expressed concern that permitting the use
    of juror testimony to impeach a verdict would undermine the
    interest in the finality of judgments, the “jurors’ willingness to
    return an unpopular verdict,” and trust in the judicial system. 
    Id.
    at 120–21.
    The evidence that Gavin seeks to submit in support of his
    claim does not fall within the ambit of any exceptions to Rule
    606(b)—it is not evidence of an external influence on or extraneous
    prejudicial information that was brought to bear on the jury’s
    decision, or evidence of racial animus. Rather, Gavin seeks to
    submit a juror’s statement about an irregularity in the jury’s
    deliberative process—the exact type of evidence that Alabama’s
    Rule 606(b) excludes. And despite Gavin’s argument that, in the
    context of premature penalty-phase jury deliberations, the no-
    impeachment rule “must yield” to his Sixth and Fourteenth

    Amendment rights to a fair and impartial jury trial, he has identified
    no clearly established federal law from the Supreme Court in
    support of that principle. Thus, the CCA’s rejection of this claim
    was not contrary to, or an unreasonable application of, any federal
    law. See 
    28 U.S.C. § 2254
    (d)(1).
    IV.    Conclusion
    Accordingly, we reverse the district court’s grant of habeas
    relief on Gavin’s ineffective-assistance claim. We affirm the denial
    of Gavin’s juror misconduct claim.

    JORDAN, Circuit Judge, concurring.
    I join Parts I, II, and III.A(ii) of Judge Branch’s opinion for
    the court. Because we conclude in Part III.A(ii) that the prejudice
    determination of the Alabama Court of Criminal Appeals was
    reasonable, it is unnecessary to address counsel’s performance in
    Part III.A(i).
    With respect to Part III.B, which concerns the juror
    misconduct claim, I agree with the result, but my reasoning is
    slightly different. When the ACCA issued its opinion in August of
    2014, the Supreme Court had held that Federal Rule of Evidence
    606(b) precluded the introduction of evidence that multiple jurors
    were intoxicated during trial, and in so doing had rejected the
    defendant’s argument that the exclusion of such evidence violated
    the Sixth Amendment. See Tanner v. United States, 
    483 U.S. 107
    ,
    123–26 (1987). And several months after the ACCA’s decision, the
    Supreme Court again affirmed the exclusion of evidence of alleged
    juror misconduct under Rule 606(b) and again rejected the
    contention that the exclusion violated the constitutional right to a
    fair trial. See Warger v. Shauers, 
    574 U.S. 40
    , 44–51 (2014) (holding
    inadmissible an affidavit by one juror that another juror had
    revealed during deliberations that she lied when questioned at voir
    dire). It was not until Peña-Rodriguez v. Colorado, 
    137 S.Ct. 855
    ,
    869–70 (2017), that the Supreme Court held that a prohibition on
    juror impeachment concerning deliberations and the verdict had to
    give way to evidence that a juror was racially biased against the
    defendant. Because Peña-Rodriguez was decided several years

    after the ACCA issued its opinion in Mr. Gavin’s case, I cannot say
    that the ACCA acted unreasonably in 2014 in applying Alabama
    Rule of Evidence 606(b) to preclude evidence of the jurors’
    premature sentencing vote. Given the AEDPA posture of this
    appeal, I would not opine on whether the rationale of Peña-
    Rodriguez extends to a scenario like the one presented here.
