    Petitioner-Appellant Shelton Jackson appeals from the district court’s
    denial of his petition for writ of habeas corpus challenging his conviction and
    death sentence. Jackson v. Workman, No. 08–CV–204–JHP–FHM, 
    2013 WL 4521143
     (N.D. Okla. Aug. 26, 2013). In 1997, Mr. Jackson was charged with the
    murder of Monica Decator in Tulsa, Oklahoma and was subsequently convicted
    and sentenced to death. Mr. Jackson raises three issues on appeal: (1) whether the
    state court’s submission to the jury of an allegedly invalid sentencing aggravator
    unconstitutionally skewed the jury’s deliberations during the penalty phase of his
    trial; (2) whether his defense lawyers provided constitutionally deficient
    representation during the penalty phase; and (3) whether the combined effect of
    these two errors warrants habeas relief even if, viewed individually, each error is
    harmless.
    We have jurisdiction pursuant to 
    28 U.S.C. §§ 1291
     and 2253(a), and we
    affirm.
    Background
    The Oklahoma Court of Criminal Appeals (OCCA) set forth the relevant
    facts in its published opinion on direct appeal. Jackson v. State, 
    146 P.3d 1149
    ,
    -2-
    1154–55 (Okla. Crim. App. 2006). We presume these facts are correct. 
    28 U.S.C. § 2254
    (e)(1).
    On the morning of April 8, 1997, Mr. Jackson killed his girlfriend Monica
    Decator, with whom he had been living for several months. The previous day,
    Mr. Jackson had been watching Ms. Decator’s two-year-old son when he “lost his
    patience” due to the child’s fussiness and crying. Jackson, 
    146 P.3d at 1154
    . He
    “picked the child up by the neck, and tossed him to the ground several times.” 
    Id.
    Later, when the child began crying again, Mr. Jackson pushed the child down
    repeatedly. After this abuse, the child could not walk, and his eyes were “glazy.”
    
    Id.
     Mr. Jackson used a screwdriver to pry the child’s mouth open because he was
    having difficulty breathing.
    The parties contest the timing and sequence of the next series of events.
    According to the state, Mr. Jackson covered the severely injured child with a
    large piece of carpet and hid him in the crawlspace of a nearby vacant house. He
    then went to a gas station, where he purchased a gallon of gasoline and used an
    ATM to empty Ms. Decator’s bank account. Later that evening, he watched
    wrestling at his uncle’s apartment, as he regularly did. When he returned home,
    he killed Ms. Decator to prevent her from reporting his child abuse to the
    authorities. He left town at noon on April 8.
    Mr. Jackson provided a different sequence of events to the police. He
    stated he left the injured child at home in bed when he went to his uncle’s house
    -3-
    to watch wrestling. When Ms. Decator returned to the house that evening, she
    heard her child crying and discovered his severe injuries. This discovery led to a
    fight with Mr. Jackson when he returned, which ended when he knocked her
    unconscious by hitting her in the head several times with a brick. According to
    Mr. Jackson, at that time he carried the child to the vacant house. When he
    returned to Ms. Decator, she had regained consciousness, and she attacked him
    with a knife. He hit her again with the brick, gained control of the knife, and
    stabbed her.
    Ms. Decator’s body was discovered at 8:30 a.m. on April 8, when
    firefighters responded to a fire at her home. Investigators concluded that
    someone had set the fire intentionally. Police arrested Mr. Jackson later that
    afternoon, when his Houston-bound bus stopped in McAlester, Oklahoma. He
    had no visible injuries. In McAlester, Mr. Jackson gave detectives a general
    location for the hidden child, but they could not find him. Mr. Jackson was then
    taken to a police station in Tulsa, where he provided more specific directions to
    find the child and gave a statement confessing to the child abuse and killing of
    Ms. Decator.
    On April 29, 1997, Mr. Jackson was charged with first degree murder, first
    degree arson, and injury to a minor child. A jury found Mr. Jackson guilty of all
    three crimes and recommended the death penalty for his murder conviction. On
    appeal, the OCCA found that Mr. Jackson’s trial attorneys were constitutionally
    -4-
    ineffective because they conceded Mr. Jackson’s guilt without consulting with
    him or obtaining his consent or acquiescence. Jackson v. State, 
    41 P.3d 395
    ,
    400–01 (Okla. Crim. App. 2001). The OCCA reversed and remanded Mr.
    Jackson’s murder conviction and death sentence for a new trial, and affirmed his
    convictions for arson and injury to a child. 
    Id. at 401
    .
    Mr. Jackson’s retrial was held in March 2003. At the guilt stage of Mr.
    Jackson’s second trial, the salient question for the jury was whether Mr. Jackson
    acted with deliberate intent to kill Ms. Decator, or whether instead he acted in
    self-defense or in the heat of passion. The jury found that Mr. Jackson intended
    to kill Ms. Decator, and he was again convicted of first degree murder. 
    Okla. Stat. Ann. tit. 21, § 701.7
    (A) (Supp. 1996).
    At the penalty phase of the second trial, the prosecution sought to prove
    four aggravating circumstances, each listed in Oklahoma’s death penalty statute:
    (1)    Ms. Decator’s murder was especially heinous, atrocious, or cruel
    (“heinous crime aggravator”);
    (2)    Mr. Jackson killed Ms. Decator for the purpose of avoiding or
    preventing a lawful arrest or prosecution for a previous crime—the
    abuse of her child (“avoid arrest aggravator”);
    (3)    Mr. Jackson posed a continuing threat to society because he would
    probably commit violent acts in the future (“continuing threat
    aggravator”); and
    (4)    During the commission of the murder of Ms. Decator, Mr. Jackson
    knowingly created a great risk of death to more than one person—the
    injured child (“great risk of death aggravator”).
    -5-
    
    Id.
     § 701.12; 
    16 R. 23
     (2003 Trial Tr.). 1
    At trial, the state rested upon the evidence presented during the guilt phase
    of the trial to prove the first three aggravators. The state offered testimony from
    the doctor who treated the child at the hospital to prove the final aggravator—that
    Mr. Jackson knowingly created a great risk of death to the child when he
    murdered Ms. Decator. After the trial judge dismissed the continuing threat
    aggravator, the jury found the remaining three aggravators applied.
    Before the jury’s deliberations, Mr. Jackson’s defense counsel presented
    mitigating evidence, much of it focused on Mr. Jackson’s life history. Mr.
    Jackson’s mother drank heavily throughout her pregnancy, and a neurologist
    testified that Mr. Jackson suffered from fetal-alcohol syndrome, causing an array
    of cognitive and functional disabilities. Mr. Jackson’s stepfather abused him
    severely. His classmates teased him for poor hygiene and a speech impediment,
    and he was committed to the Louisiana Department of Corrections when he was
    twelve years old. He spent three difficult years in a correctional facility that the
    Department of Justice later accused of failing to protect children from abuse.
    Mr. Jackson’s defense counsel also presented as mitigating evidence the
    character witness testimony of Arthur Farahkhan. Mr. Farahkhan worked with
    1
    In conjunction with the filing of his opening brief, Mr. Jackson
    submitted to this court a CD containing an electronic version of the record on
    appeal. We cite directly to this electronic record, and to its various folders and
    volumes, in accordance with Mr. Jackson’s briefing.

    Mr. Jackson developing a program to assist disadvantaged youth. He testified
    about Mr. Jackson’s leadership qualities and his genuine desire to improve life in
    his neighborhood. He stated that Mr. Jackson’s life would have value in prison.
    Mr. Farahkhan had provided similar testimony in Mr. Jackson’s first trial.
    There he stated that he “believ[ed] in the death penalty.” 
    11 R. 2189
     (1998 Trial
    Tr.). He reconciled his general belief in the death penalty with his support for
    Mr. Jackson because he did not think Mr. Jackson’s murder of Ms. Decator was
    premeditated. 
    Id.
     The first trial judge sustained an objection by the prosecution
    and admonished the jurors to disregard Mr. Farahkhan’s comment regarding
    premeditation.
    Prior to testifying at the second trial, Mr. Farahkhan “made it crystal clear”
    to Mr. Jackson’s counsel that, consistent with his previous testimony, he believed
    Mr. Jackson would deserve the death penalty if the murder of Ms. Decator was
    premeditated. 
    1 R. 219
     (Post-Conviction). Despite this warning, Mr. Jackson’s
    counsel called Mr. Farahkhan to testify. When, on cross-examination, Mr.
    Farahkhan agreed with the prosecution that “the death penalty would be
    appropriate” if Mr. Jackson “intentionally” killed Ms. Decator, Mr. Jackson’s
    counsel did not object or ask Mr. Farahkhan any further questions. 
    17 R. 129
    –30
    (2003 Trial Tr.).
    Mr. Jackson filed a direct appeal from the conviction and death sentence
    resulting from his second trial. He raised ten propositions of error, including that
    -7-
    there was insufficient evidence to prove beyond a reasonable doubt the great risk
    of death aggravator. The OCCA affirmed the murder conviction and death
    sentence. Jackson, 
    146 P.3d at 1168
    . Mr. Jackson then sought post-conviction
    relief, raising seven propositions of error. Among other things, he argued that his
    trial counsel was ineffective in investigating and presenting Mr. Farahkhan as a
    mitigation witness and in failing to object to his testimony during cross-
    examination. Mr. Jackson also argued that his appellate counsel was ineffective
    for failing to raise that claim on direct appeal. 
    1 R. 274
    , 276 (Post-Conviction).
    The OCCA denied all requested relief in an unpublished opinion, 
    1 R. 273
     (Post-
    Conviction) (PCD 2003-670), and the United States Supreme Court denied Mr.
    Jackson’s petition for a writ of certiorari, Jackson v. Oklahoma, 
    552 U.S. 838
    (2007).
    Mr. Jackson initiated this federal habeas action pursuant to 
    28 U.S.C. § 2254
     in October 2008. He again argued the evidence was insufficient to prove
    beyond a reasonable doubt the great risk of death aggravator and that both his
    trial and appellate counsel were constitutionally ineffective. The federal district
    court denied the petition but granted a COA on Mr. Jackson’s ineffective
    assistance claim. Jackson, 
    2013 WL 4521143
    , at *45. We expanded the COA to
    include Mr. Jackson’s improper aggravator claim.
    -8-
    Discussion
    The standard of review applicable to Mr. Jackson’s claims depends on
    whether and how the state court resolved those claims. Alverson v. Workman,
    
    595 F.3d 1142
    , 1146 (10th Cir. 2010). When a state court has adjudicated a claim
    on the merits, a petitioner may obtain federal habeas relief only if the decision
    was “contrary to, or involved an unreasonable application of, clearly established
    Federal law, as determined by the Supreme Court of the United States,” or 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). Federal
    law is “clearly established” when it is embodied in a holding of the Supreme
    Court. Carey v. Musladin, 
    549 U.S. 70
    , 74 (2006); Williams v. Taylor, 
    529 U.S. 362
    , 412 (2000).
    Our review under § 2254(d) is “highly deferential” and requires us to give
    “state-court decisions . . . the benefit of the doubt.” Littlejohn v. Trammell, 
    704 F.3d 817
    , 824 (10th Cir. 2013) (quoting Woodford v. Visciotti, 
    537 U.S. 19
    , 24
    (2002) (per curiam)). When we review a state court’s application of federal law,
    “we are precluded from issuing the writ simply because we conclude in our
    independent judgment that the state court applied the law erroneously or
    incorrectly. Rather, we must be convinced that the application was also
    objectively unreasonable.” McLuckie v. Abbott, 
    337 F.3d 1193
    , 1197 (10th Cir.
    2003) (citing Williams v. Taylor, 
    529 U.S. 362
    , 412 (2000)).

    I.    The Submission to the Jury of the Great Risk of Death Aggravator
    A.     The Alleged Invalidity of the Great Risk of Death Aggravator
    Mr. Jackson’s first argument is that the trial court’s submission to the jury
    of the great risk of death aggravator unconstitutionally skewed its deliberations
    during the penalty phase of his second trial. Under Oklahoma law, the great risk
    of death aggravator focuses on whether “another person was endangered by the
    defendant’s actions in killing the victim.” Hanson v. State, 
    206 P.3d 1020
    , 1033
    (Okla. Crim. App. 2009). The aggravator is “established by acts which create a
    great risk of death to another person in close proximity to the homicidal act in
    terms of time, location, and intent.” Harris v. State, 
    84 P.3d 731
    , 751 (Okla.
    Crim. App. 2004). “The gravamen of the circumstance is not the number of
    persons killed, but the callous creation of the risk to more than one person.”
    Williams v. State, 
    22 P.3d 702
    , 724 (Okla. Crim. App. 2001).
    Mr. Jackson strenuously objected to the prosecution’s submission of the
    great risk of death aggravator to the jury. He contended that Oklahoma law
    requires juries applying the great risk of death aggravator to focus on the risk to
    another person created by the homicidal act itself. Yet, here, the child’s injuries
    were far removed in time, place, and intent from the murder of Ms. Decator.
    According to Mr. Jackson, the child was not present in the house when he killed
    Ms. Decator; he had been hidden in another location roughly twelve hours earlier.
    See Hanson, 
    206 P.3d at 1033
     (requiring evidence that another person was “so
    -10-
    near the victim at the time of the murder and consequently put in jeopardy of
    suffering real harm”); Miller v. State, 
    313 P.3d 934
    , 988 (Okla. Crim. App. 2013)
    (applying the great risk of death aggravator only “where the homicidal act at issue
    puts another person at great risk of death, because of that other person’s ‘close
    proximity’ to the victim at the time of the homicidal act”); Salazar v. State, 
    919 P.2d 1120
    , 1123 (Okla. Crim. App. 1996) (“In the majority of the cases in which
    this aggravator has been upheld, the endangered bystanders who suffered a great
    risk of death were either in the line of the defendant’s fire or were
    contemporaneously injured or killed by the defendant.”); but see Ryder v. State,
    
    83 P.3d 856
    , 874 (Okla. Crim. App. 2004) (holding that a defendant who killed a
    woman, waited for her son to return home, and then killed her son had created a
    great risk of death to more than one person; although not simultaneous, the two
    murders were “in close proximity”).
    To the contrary, the state argued at trial and on appeal that the aggravator
    was appropriate because Mr. Jackson acted with a single “murderous intent” when
    he hid the severely injured child where authorities were unlikely to find him and
    then murdered his mother to prevent her from reporting the abuse. Jackson, 
    146 P.3d at 1163
    . Ms. Decator’s murder created a great risk of death to the child
    because, as his mother, she was the only person likely to search for and find him
    before he died from his injuries. 
    Id.
    -11-
    The trial court agreed with the state, viewing the incidents with Ms.
    Decator and her child as part of a single continuing transaction warranting
    application of the aggravator. On direct appeal after the second trial, the OCCA
    did not directly address the merits of Mr. Jackson’s or the state’s arguments when
    it affirmed his conviction and sentence. The OCCA noted that “[t]he
    circumstances here are unlike those in any of our prior cases and the opposing
    parties at oral argument each made persuasive arguments in support of their
    position.” 
    Id. at 1164
    . Regardless, the court continued, “[w]e need not decide the
    issue” because, even if Mr. Jackson’s conduct did not constitute the knowing
    creation of a great risk of death to more than one person, “the submission of this
    aggravator to the jury did not skew the jury’s decision to impose the death
    penalty.” 
    Id.
    The OCCA based this analysis on Brown v. Sanders, 
    546 U.S. 212
     (2006),
    which “set forth a test to determine when a death sentence must be set aside if an
    aggravating circumstance is invalidated.” Jackson, 
    146 P.3d at 1164
    . Under
    Sanders, “[a]n invalidated sentencing factor . . . will render the sentence
    unconstitutional by reason of its adding an improper element to the aggravation
    scale in the weighing process unless one of the other sentencing factors enables
    the sentencer to give aggravating weight to the same facts and circumstances.”
    
    Id.
     (quoting Sanders, 
    546 U.S. at 220
    ). Therefore, the OCCA explained, a
    sentence will stand if “the jury could have properly considered the evidence used
    -12-
    to support the invalidated aggravator anyway because it also supported a separate
    and valid aggravator.” 
    Id.
     Because the evidence presented to support the
    allegedly invalid great risk of death aggravator was also “relevant to support the
    aggravator that he committed the murder of Decator ‘to avoid arrest or
    prosecution,’” the jury’s deliberations were not unconstitutionally skewed. 
    Id.
    B.     The Applicability of Sanders in Oklahoma
    Given the procedural posture of Mr. Jackson’s claim and the OCCA’s
    decision, we need not determine whether the great risk of death aggravator was
    indeed appropriate under these facts. We must determine only whether the
    OCCA’s decision to affirm Mr. Jackson’s death sentence was an unreasonable
    application of Sanders. Mr. Jackson contends the OCCA’s decision was “contrary
    to clearly established federal law” because Sanders, upon which it relied, does not
    apply in Oklahoma. Application of a “rule different from the governing law set
    forth in [Supreme Court] cases” is a clear violation of § 2254(d)(1). Bell v. Cone,
    
    535 U.S. 685
    , 694 (2002). 2
    2
    The state asserts Mr. Jackson waived his argument about the applicability
    of Sanders in Oklahoma by failing to raise it below. In his briefing, Mr. Jackson
    acknowledges he “cannot quarrel with the thrust of the State’s assertion: his
    theory as to why he satisfies the § 2254(d) standard is new.” Aplt. Rep. Br. 11.
    Although we generally decline to address theories a party did not develop before
    the district court, United States v. Windrix, 
    405 F.3d 1146
    , 1156 (10th Cir. 2005),
    Mr. Jackson has argued vigorously at every stage of this litigation that the
    submission of the great risk of death aggravator to the jury violated his
    constitutional rights. His position on appeal that the OCCA misapplied Sanders is
    -13-
    As described in Sanders, Supreme Court precedent historically has
    distinguished between “weighing” and “non-weighing” death penalty
    jurisdictions. 
    546 U.S. at 216
    . Generally, in order to impose the death penalty in
    a weighing jurisdiction such as Oklahoma, Duckett v. Mullin, 
    306 F.3d 982
    , 1001
    n.9 (10th Cir. 2002), a sentencer must first find a defendant guilty of capital
    murder and determine that at least one statutory factor rendering a defendant
    eligible for a death sentence applies. Then, to decide whether a “death-eligible”
    defendant will in fact receive the death penalty, the sentencer must weigh any
    mitigating evidence against the statutorily-defined factors that rendered the
    defendant death-eligible in the initial eligibility stage. Sanders, 
    546 U.S. at 217
    ;
    Stringer v. Black, 
    503 U.S. 222
    , 229 (1992).
    In weighing states, “[s]ince the eligibility factors by definition identified
    distinct and particular aggravating features, if one of them was invalid the jury
    could not consider the facts and circumstances relevant to that factor as
    aggravating in some other capacity.” Sanders, 
    546 U.S. at 217
    . Thus, the
    sentencer’s consideration of an invalid eligibility factor “necessarily skewed its
    balancing of aggravators with mitigators” and therefore required automatic
    reversal of the sentence, “unless a state appellate court determined the error was
    closely intertwined with his prior position and involves pure matters of law
    appropriate for our review under these circumstances.
    -14-
    harmless or reweighed the mitigating evidence against the valid aggravating
    factors.” 
    Id.
    In a nonweighing state—just as in a weighing state—a sentencer must limit
    its initial consideration of whether a defendant is death-eligible to factors
    expressly described in the applicable statute. However, once the sentencer has
    reached the secondary deliberation stage, it may consider aggravating factors
    beyond those enumerated eligibility factors to determine whether to impose a
    death sentence. In this way, the sentencer in a nonweighing state is allowed
    broader discretion to consider aggravating and mitigating circumstances at the
    secondary stage. Because of this broader discretion, the “automatic skewing”
    problems arising in weighing states do not necessarily follow from the
    introduction of an invalid eligibility factor in nonweighing states. For example,
    death penalty deliberations are not necessarily skewed when the aggravating
    factors are entirely different from the eligibility factors, or when the aggravating
    factors add to the eligibility factors categories that would allow the same facts
    and circumstances to be weighed in aggravation under a different rubric. 
    Id.
    Thus, determining whether the submission of an invalid factor amounted to
    constitutional error in nonweighing states historically required a more complex
    analysis than the weighing-state “automatic skewing” rule provided.
    The Supreme Court in Sanders noted that “[t]his weighing/non-weighing
    scheme is accurate as far as it goes, but it now seems to us needlessly complex
    -15-
    and incapable of providing for the full range of possible variations.” 
    Id. at 219
    .
    For example, the same concerns giving rise to the automatic skewing rule in
    weighing states would arise if a sentencing factor, rather than an eligibility factor,
    was later found to be invalid. In such a case, the weighing process would be
    automatically skewed for the same reason: “The sentencer might have given
    weight to a statutorily or constitutionally invalid aggravator.” 
    Id.
     at 219–20. Yet,
    in some cases the “automatic skewing” could be “shown to be illusory for the
    same reason that separates weighing States from non-weighing States: One of the
    other aggravating factors . . . made it entirely proper for the jury to consider as
    aggravating the facts and circumstances underlying the invalidated factor.” 
    Id. at 220
    .
    For these reasons, the Supreme Court stated:
    We think it will clarify the analysis, and simplify the
    sentence-invalidating factors we have hitherto applied to
    non-weighing States, if we are henceforth guided by the following
    rule: An invalidated sentencing factor (whether an eligibility factor
    or not) will render the sentence unconstitutional by reason of its
    adding an improper element to the aggravation scale in the weighing
    process unless one of the other sentencing factors enables the
    sentencer to give aggravating weight to the same facts and
    circumstances.”
    
    Id. at 220
     (citation and footnote omitted).
    Here, Mr. Jackson argues the new rule announced in Sanders expressly
    applies only in nonweighing states; in weighing states, including Oklahoma, the
    automatic skewing rule remains good law. Thus, submission to the jury of an
    -16-
    invalid aggravator is per se constitutional error. Mr. Jackson primarily highlights
    the court’s emphasis on its intent to “simplify the sentence-invalidating factors
    we have hitherto applied to non-weighing States.” 
    Id.
     (emphasis added). Yet,
    given the whole of the Court’s discussion, we do not believe this phrasing
    restricts the scope of the streamlined rule to nonweighing jurisdictions.
    Indeed, it is evident from the structure of the opinion that the Court
    intended to eliminate the outmoded weighing-nonweighing dichotomy in its
    entirety. By choosing first to elaborate, at great length, on the many problems
    arising from the “needlessly complex” distinction, the Court signaled its intent to
    eliminate that distinction. 3 Then, after setting forth the new rule, the Court
    applied it to the case at hand, explaining it was “leaving aside the
    weighing/non-weighing dichotomy and proceeding to the more direct analysis set
    forth earlier in this opinion: All of the aggravating facts and circumstances that
    the invalidated factor permitted the jury to consider were also open to their proper
    consideration under one of the other factors.” 
    Id.
     at 222–23. Thus, no
    constitutional violation had occurred because the invalid factor could not have
    “skewed” the sentence. 
    Id. at 223
    . The dissenting Justices interpreted this
    3
    Among other problems the Court highlighted, determining in the first
    instance whether a state employs a weighing or nonweighing scheme can be
    difficult given the myriad complexities of state death penalty statutes. Cf. 
    id.
     at
    219 n.5; 
    id.
     at 234–35 (Breyer, J., dissenting). In fact, the majority in Sanders
    believed California to be a nonweighing state, while Justice Stevens in dissent
    believed it to be a weighing state.

    language to “modify our settled law,” 
    id. at 228
    , and wholly “abolish (or at least
    diminish the importance of)” the outmoded dichotomy, 
    id. at 239
    .
    Accordingly, we recently applied the Sanders framework to an Oklahoma
    sentence, although the petitioner did not make the argument that Sanders applies
    only in nonweighing states, an argument we now reject. Hanson v. Sherrod, 
    797 F.3d 810
    , 848-50 (10th Cir. 2015). Several other circuits have likewise applied a
    uniform Sanders rule. Sutton v. Bell, 
    645 F.3d 752
    , 759 (6th Cir. 2011) (applying
    Sanders to a death sentence in Tennessee, a weighing state); Jennings v.
    McDonough, 
    490 F.3d 1230
    , 1255 n.22 (11th Cir. 2007) (“[I]t is probable that the
    Court’s decision in [Sanders] announced a uniform rule to be applied in weighing
    and nonweighing states alike.”); Rousan v. Roper, 
    436 F.3d 951
    , 963 (8th Cir.
    2006) (apparently interpreting Sanders as applying one rule to weighing and
    nonweighing states); see also 1 Wayne R. LaFave, Substantive Criminal Law
    § 3.5, at 16, n.112 (2d ed. Supp. 2007) (“While an approach different from that in
    Zant was once used in so-called ‘weighing statutes,’ the Court later, in Brown v.
    Sanders, adopted a single rule for all statutes . . . .”); The Supreme Court, 2005
    Term—Leading Cases, 
    120 Harv. L. Rev. 134
    , 144 (2006) (“The new Sanders rule
    clarifies and provides predictability to the weighing-nonweighing distinction by
    jettisoning it in favor of a simplified rule.”); but see Wilson v. Mitchell, 
    498 F.3d 491
    , 507 (6th Cir. 2007) (“This rule apparently modifies the analysis for
    -18-
    non-weighing States, but leaves intact the Court’s prior jurisprudence regarding
    weighing states.”). 4
    Thus, we hold that Sanders established a uniform rule applying in both
    weighing and nonweighing states. Therefore, the OCCA looked to the proper
    “clearly established” federal law when it relied on Sanders to affirm Mr.
    Jackson’s sentence.
    C.     The Distinction Between Admissibility and “Aggravatability”
    Mr. Jackson next argues that, even if Sanders is applicable in Oklahoma,
    the OCCA nevertheless misinterpreted the Supreme Court’s guidance by
    conflating the question whether evidence is admissible with whether a jury may
    properly consider evidence as giving aggravating weight to a valid sentencing
    factor.
    As discussed in detail above, the Court in Sanders held that an invalidated
    sentencing factor will not render a death sentence unconstitutional if one of the
    other sentencing factors enables the sentencer to give aggravating weight to the
    same facts and circumstances. Responding to concerns raised by the dissent, the
    4
    Mr. Jackson cites two unpublished Tenth Circuit orders, both preceding
    Hanson, in which our language suggested Sanders may apply only in nonweighing
    states. Dunlap v. Clements, 476 F. App’x 162, 171 (10th Cir. 2012)
    (unpublished); Ochoa v. Workman, 451 F. App’x 718 (10th Cir. 2011)
    (unpublished). However, in neither of these orders did we directly address the
    scope and applicability of Sanders, and, regardless, unpublished orders lack
    precedential value. Fed. R. App. P. 32.1(A).
    -19-
    majority in Sanders explained that this rule is not “an inquiry based solely on the
    admissibility of the underlying evidence.” 
    546 U.S. at 220
     (emphasis added). If
    the presence of an invalidated sentencing factor allowed the jury to hear and
    consider evidence that would not have been before it otherwise, “due process
    would mandate reversal without regard to the rule we apply here.” 
    Id. at 221
    .
    Instead, the Court’s central concern in Sanders was “the jury’s weighing in favor
    of death a factor that should not have been part of its calculus.” 
    Id.
     at 221 n.7
    (emphasis added).
    According to Mr. Jackson, the OCCA ignored this guidance and confused
    admissibility and aggravating weight by holding that, “[i]f the jury could have
    properly considered the evidence used to support the invalidated aggravator
    anyway because it also supported a separate and valid aggravator . . . the jury has
    not considered any improper evidence and has not weighed any improper
    aggravating evidence against the mitigating evidence in arriving at its sentence.”
    Jackson, 
    146 P.3d at 1164
     (emphasis added). The OCCA further explained that,
    here, “the ‘great risk of death’ aggravator was not supported by any evidence that
    was not also admissible to support a separate aggravator.” 
    Id.
     (emphasis added).
    Mr. Jackson contends this language underscores the OCCA’s improper focus on
    the admissibility of the evidence—which, as the Supreme Court noted in Sanders,
    raises separate due process concerns—rather than the aggravating weight of that
    evidence.
    -20-
    Mr. Jackson argues the OCCA failed to appreciate that, “[w]hile all valid
    aggravating evidence is admissible, not all admissible evidence is aggravating.”
    Aplt. Br. 48. Even if evidence of the child’s injuries “in and of themselves” was
    admissible, these injuries “could not properly be given aggravating weight” under
    the valid avoid arrest aggravator. Id. at 49. Instead, the child’s injuries would be
    admissible only for the limited purpose of proving Mr. Jackson’s motive for
    killing Ms. Decator, to avoid arrest or prosecution for child abuse. Ultimately,
    only this motive is important, and thus only Mr. Jackson’s awareness of the
    nature and extent of the child’s injuries should receive aggravating weight. Id. at
    49–50.
    Although the OCCA’s use of the phrases “consider any improper evidence”
    and “admissible to support a separate aggravator” may be imprecise, Mr. Jackson
    overemphasizes the import and effect of any imprecision. It is clear from the
    OCCA’s analysis that it appreciated the proper boundary between the general
    admissibility of evidence at trial and the use of evidence to give aggravating
    weight to a valid sentencing factor. In accord with Sanders, the core of its
    opinion is that there was no constitutional error because the facts and
    circumstances the jury considered as aggravating under the allegedly invalid great
    risk of death factor—the nature and extent of the child’s injuries—could be given
    aggravating weight under the valid avoid arrest factor.
    -21-
    Further, consideration of the injuries in and of themselves surely informs
    Mr. Jackson’s awareness of those injuries and his related motive. The more
    severe the nature and extent of the injuries, the more likely Mr. Jackson was to be
    aware of them and concerned about possible arrest and prosecution.
    Additionally, as the state points out, a sentencing jury does not weigh
    evidence independently during its deliberations. Instead, the jury considers the
    evidence presented to determine if the state has proven the required elements of
    an aggravating circumstance beyond a reasonable doubt. If the aggravating
    circumstance has been proven, the jury then weighs that circumstance—not the
    underlying evidence itself—against any mitigating circumstances. See Vernon’s
    Okla. Forms 2d, OUJI-CR 4-80 (“If you unanimously find that one or more of the
    aggravating circumstances existed beyond a reasonable doubt, the death penalty
    shall not be imposed unless you also unanimously find that any such aggravating
    circumstance or circumstances outweigh the finding of one or more mitigating
    circumstances.”). Thus, if evidence may be considered to help a jury decide if an
    aggravating circumstance applies, as the OCCA determined was proper here, that
    evidence has been given appropriate aggravating weight.
    For these reasons, the OCCA’s application of Sanders, finding the
    physician’s testimony could properly be considered to support the valid avoid
    arrest factor, was not objectively unreasonable. McLuckie, 
    337 F.3d at 1197
    .
    D.     The Treating Physician’s Testimony
    -22-
    Mr. Jackson next argues that the OCCA misapplied Sanders because “the
    doctor’s testimony would not have been admissible to prove the avoid-arrest
    factor. And if it would not have been admissible to prove the avoid-arrest factor,
    of course, neither could it have carried aggravating weight under that factor.”
    Aplt. Br. 56. We disagree. During the guilt phase, the court shielded the jury
    from most evidence about the nature and extent of the child’s injuries. The trial
    judge allowed the prosecutors to characterize the child’s injuries as “serious” but
    “prohibit[ed] the state from going into any detail as to any injuries suffered” by
    the child. 
    9 R. 3
    –4 (2003 Trial Tr.).
    Mr. Jackson agrees that some facts concerning the child’s injuries were
    properly before the jury because they suggested he murdered Ms. Decator to
    avoid arrest for child abuse. However, he argues the admitted facts should have
    been “limited to what Jackson himself saw and knew about the child’s condition.”
    Aplt. Br. 59. The OCCA erred, he contends, because the doctor’s testimony did
    not speak to what Mr. Jackson appreciated about the injuries “so much as what
    highly skilled trauma surgeons equipped with sophisticated brain-imaging devices
    could appreciate.” Aplt. Rep. Br. 32. Essentially, he argues only the facts
    contained in his own statement to the police soon after his arrest were admissible.
    At that time, Mr. Jackson told the detectives that the child’s body was “cramming
    up,” that his eyes “had this glaze upon ‘em, you know, like wasn’t nothing there,”
    -23-
    and that he “knew something was very wrong.” State’s Ex. 54. By contrast, the
    doctor’s testimony, involving a substantially more detailed and clinical account of
    the child’s injuries and subsequent treatment, “revealed nothing about what
    Jackson actually knew of the injuries.” Aplt. Br. 60.
    As Mr. Jackson notes, the OCCA disagreed that the physician’s testimony
    lent no support to the valid avoid arrest aggravator. Id. at 52. It held that the
    doctor’s testimony “showed that Jackson appreciated the seriousness of the
    child’s condition and deliberately murdered the child’s mother to avoid being held
    responsible.” Jackson, 
    146 P.3d at 1164
    . We conclude that fair-minded jurists
    could agree. The more severe the nature of the child’s injuries, as perhaps only a
    physician can fully and accurately describe, the more likely Mr. Jackson was
    aware of the gravity of his crime and concerned about the ramifications.
    We cannot find this determination to be unreasonable under our deferential
    standard, and Mr. Jackson has not demonstrated that he is entitled to relief under
    § 2254(d)(1). 5
    II.   Ineffective Assistance of Counsel Concerning Mr. Farahkhan’s Testimony
    A.     Mr. Farahkhan’s Character Witness Testimony
    Mr. Jackson’s next argument is that his lawyers made a critical error during
    his sentencing proceedings by allowing Mr. Farahkhan to “testify that Jackson
    5
    As such, we need not address Mr. Jackson’s remaining arguments
    regarding the proper procedure for harmless-error analysis.
    -24-
    deserved the death penalty.” Aplt. Br. 71–72. Mr. Jackson argues this error
    rendered his assistance constitutionally ineffective under the Sixth Amendment.
    As discussed above, Mr. Jackson’s lawyers asked Mr. Farahkhan to testify
    as a character witness in support of Mr. Jackson’s case in mitigation during the
    penalty phase of both his first and second trials. Prior to the second trial, Mr.
    Farahkhan met with Mr. Jackson’s lawyers and expressed concerns that his views
    on the death penalty might pose a problem. He advised them that he “believe[d]
    in the death penalty under some circumstances, including premeditated murder
    and in cases of ambush.” 
    1 R. 219
     (Post-Conviction). Mr. Farahkhan did not
    believe Mr. Jackson had committed premeditated murder, but he informed them
    that, “if this case was a case of premeditated murder and if Mr. Jackson was
    waiting to kill Ms. Decatur [sic] because of what he did . . . then he would
    deserve the death penalty.” 
    Id.
    On direct examination during the second trial, Mr. Farahkhan testified that
    Mr. Jackson volunteered in a community-based drug-abuse program, which served
    a highly distressed area of north Tulsa. 
    17 R. 124
    –26 (2003 Trial Tr.).
    According to Mr. Farahkhan, Mr. Jackson “really wanted to see those people in
    Comanche who had alcohol, drug, gang problems, to be able to overcome those
    problems.” Id. at 126. Mr. Farahkhan testified that Mr. Jackson’s life in prison
    would have value because of his leadership qualities and genuine desire to
    improve the lives of others. Id. at 127–28.
    -25-
    The following exchange occurred during Mr. Farahkhan’s cross-
    examination:
    Prosecutor: Did you know or do you know that [Mr. Jackson]
    intentionally bludgeoned his girlfriend, Monica Decator, with a brick
    at least seven times on the head, then stabbed her in the neck at least
    eight times cutting her jugular, her common carotid artery, then stuck
    a knife two times right by her heart? Did you know he did that?
    Mr. Farahkhan: I listened closely to the language you used, and you
    said intentionally. Did I know that he intentionally did that?
    Prosecutor: Yes.
    Mr. Farahkhan: No, I did not know that he intentionally did that.
    Prosecutor: Does that change your opinion any?
    Mr. Farahkhan: If I accept what you said, that he intentionally did it,
    it would change my opinion. But I don’t believe that he intentionally
    did it.
    Prosecutor: If you believe that he intentionally did it, do you think
    the death penalty would be appropriate?
    Mr. Farahkhan: Yes.
    Id. at 129–30. Mr. Jackson’s counsel did not object during this exchange or ask
    Mr. Farahkhan any further questions.
    B.     The Doubly-Deferential Strickland Standard Under AEDPA
    In his state post-conviction petition, Mr. Jackson argued his trial lawyers
    were constitutionally ineffective for, among other things: (1) calling Mr.
    Farahkhan to testify in the first instance, despite knowing Mr. Farahkhan
    -26-
    approved of the death penalty in instances of premeditated murder; and (2) failing
    to object during Mr. Farahkhan’s damaging cross-examination.
    The OCCA first held that their “strategy in calling Farahkhan as a witness
    in Jackson’s capital sentencing proceeding was neither unreasonable nor
    unsound” under Strickland v. Washington, 
    466 U.S. 668
     (1984). 
    1 R. 277
     (Post-
    Conviction). Furthermore, the fact that his lawyers did not object during Mr.
    Farahkhan’s cross-examination did not render counsel constitutionally ineffective.
    Although the government’s hypothetical question—whether Mr. Farahkhan’s
    opinion would change if he knew Mr. Jackson killed Ms. Decator intentionally—
    was improper, the OCCA denied relief. 
    1 R. 278
     (Post-Conviction). The court
    emphasized that Mr. Farahkhan presented ample relevant mitigating evidence for
    the jury to consider, and any error on the part of either the prosecution or defense
    was harmless. “[T]he jury . . . was not misled by this exchange because it was
    evident that Farahkhan was not advocating the death penalty for his friend. . . .
    [W]e do not find that his testimony on cross-examination either erased the
    benefits of his testimony on direct examination or affected the outcome of the
    second stage of this trial.” Id. at 278.
    Here, Mr. Jackson acknowledges that “his lawyers’ threshold decision to
    call Farahkhan as a witness was not in itself an objectively unreasonable
    strategy.” Aplt. Br. 78. Mr. Farahkhan provided mitigating evidence about
    positive aspects of Mr. Jackson’s character. However, Mr. Jackson argues his
    -27-
    lawyers’ silence following the prosecutor’s questions on cross-examination
    rendered their assistance constitutionally ineffective. Further, they failed to file a
    motion in limine prior to Mr. Farahkhan’s testimony to limit the scope of cross-
    examination, did not ask the judge to instruct the jury to disregard the damaging
    testimony, and declined to conduct a rehabilitative re-direct examination of Mr.
    Farahkhan. Id. at 82–83. Their inaction, Mr. Jackson argues, violated his Sixth
    Amendment rights.
    Generally, to prevail on an ineffective assistance of counsel claim under
    Strickland, a petitioner must show: (1) his lawyers’ performance was deficient
    such that they effectively failed to function as the “counsel” guaranteed to all
    criminal defendants by the Sixth Amendment, and (2) their deficient performance
    so prejudiced the defense that the defendant was deprived of a fair trial. 
    466 U.S. at 687
    . The Supreme Court has “declined to articulate specific guidelines for
    appropriate attorney conduct and instead ha[s] emphasized that ‘[t]he proper
    measure of attorney performance remains simply reasonableness under prevailing
    professional norms.’” Wiggins v. Smith, 
    539 U.S. 510
    , 521 (2003) (quoting
    Strickland, 
    466 U.S. at 688
    ). We “must indulge a strong presumption that
    counsel’s conduct [fell] within the wide range of reasonable professional
    assistance.” Strickland, 
    466 U.S. at 689
    . An ineffective assistance claim may be
    rejected based upon an inadequate showing of deficient performance or prejudice,
    or both. 
    Id. at 697
    .
    -28-
    Moreover, where a state court has adjudicated an ineffective assistance of
    counsel claim on the merits, as the OCCA did here, a petition for habeas relief
    cannot be granted unless the state 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).
    Given that the standards of review under both Strickland and AEDPA are
    “highly deferential,” habeas review of ineffective assistance claims is “doubly
    so.” Harrington v. Richter, 
    562 U.S. 86
    , 105 (2011). We defer both to counsel’s
    strategic decisions about how best to represent his client and to the state court’s
    determination that counsel’s performance was not deficient. See Yarborough v.
    Gentry, 
    540 U.S. 1
    , 5–6 (2003) (per curiam). We grant relief only where a state
    court disposition “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
    ; see also Knowles v.
    Mirzayance, 
    556 U.S. 111
    , 123 (2009) (“The question is not whether a federal
    court believes the state court’s determination under the Strickland standard was
    incorrect but whether that determination was unreasonable—a substantially higher
    threshold.”).
    -29-
    C.     The OCCA’s Strickland Analysis
    Mr. Jackson has not met his substantial burden of showing the OCCA
    lacked any justification for denying his ineffective assistance claim, that the
    applicability of a Supreme Court holding was so obvious there could be “no
    fairminded disagreement.” White v. Woodall, 
    134 S. Ct. 1697
    , 1706 (2014).
    Even assuming his lawyers’ inaction after Mr. Farahkhan’s testimony constituted
    deficient performance, Mr. Jackson has not shown the OCCA was unreasonable in
    its determination that there was no prejudice. To establish prejudice, Mr. Jackson
    must show that “there is a reasonable probability that, but for counsel’s
    unprofessional errors, the result of the proceeding would have been different.”
    Wiggins, 
    539 U.S. at 534
    . “A reasonable probability is a probability sufficient to
    undermine confidence in the outcome.” 
    Id.
     “In assessing prejudice, we reweigh
    the evidence in aggravation against the totality of available mitigating evidence.”
    
    Id.
     The prejudice prong is satisfied if at least one juror would have struck a
    different balance. 
    Id. at 537
    .
    Before Mr. Farahkhan’s testimony, the jury heard substantial evidence of a
    heinous crime in graphic detail. They heard about how Mr. Jackson brutally beat
    a two-year-old child and, to avoid being held responsible, placed the injured child
    underneath a vacant house in near-freezing temperatures. He murdered his
    girlfriend by hitting her repeatedly in the face and head with a brick and stabbing
    her multiple times in the neck and chest, and he set fire to her house. On the
    -30-
    other hand, the jury also heard mitigation evidence about Mr. Jackson’s difficult
    childhood and about the physical and mental limitations he faced due to his
    mother’s alcohol abuse during pregnancy. Given this ample evidence, both
    weighing for and against the death penalty, the OCCA properly concluded there
    was no reasonable probability that, absent Mr. Farahkhan’s single damaging
    statement, the jury’s deliberations would have been different.
    For these reasons, the OCCA reasonably rejected Mr. Jackson’s ineffective
    assistance of counsel claim.
    III.   Cumulative Error
    Mr. Jackson’s final argument on appeal is that the aggregate impact of
    errors in his case cannot be excused. Aplt. Br. 94. Under cumulative error
    review, a court “merely aggregates all the errors that individually have been
    found to be harmless, and therefore not reversible, and it analyzes whether their
    cumulative effect on the outcome of the trial is such that collectively they can no
    longer be determined to be harmless.” Hamilton v. Mullin, 
    436 F.3d 1181
    , 1196
    (10th Cir. 2006) (citing Workman v. Mullin, 
    342 F.3d 1100
    , 1116 (10th Cir.
    2003)). Mr. Jackson argues that the “submission of the invalid sentencing factor
    inflated the aggravation side of the scale, while the failure to object to
    Farahkhan’s testimony weakened the mitigation calculus.” Aplt. Br. 95. As we
    have noted, “cumulative-error in the federal habeas context applies only where
    there are two or more actual constitutional errors.” Thacker v. Workman, 678
    -31-
    F.3d 820, 849 (10th Cir. 2012). That is not the case here and Mr. Jackson’s
    cumulative error is unavailing.
    AFFIRMED. 6
    6
    We deny Mr. Jackson’s renewed request for a certificate of appealability
    (COA) on the issue of whether a jury must be instructed that it must find
    aggravating circumstances outweigh the mitigating circumstances beyond a
    reasonable doubt. Circuit precedent forecloses this claim. See Matthews v.
    Workman, 
    577 F.3d 1175
    , 1195 (10th Cir. 2009).
    -32-
