    KENNETH GLENN THOMAS,
    Petitioner-Appellee,
    versus
    RICHARD F. ALLEN,
    Respondent-Appellant.
    Appeal from the United States District Court
    for the Northern District of Alabama
    (May 27, 2010)
    Before DUBINA, Chief Judge, BARKETT and WILSON, Circuit Judges.
    DUBINA, Chief Judge:
    Appellant, Richard Allen, Commissioner of the Alabama Department of
    Corrections, appeals the district court order granting Kenneth Glenn Thomas
    penalty phase habeas relief based on its finding that Thomas is mentally retarded
    and ineligible for execution pursuant to Atkins v. Virginia, 
    536 U.S. 304
    , 
    122 S. Ct. 2242
     (2002). Because we conclude that the district court did not clearly err in
    its mental retardation finding, we affirm.
    I. BACKGROUND
    A Limestone County, Alabama, jury convicted Thomas for the intentional
    murder of Flossie McLemore during the course of a burglary. The jury
    unanimously recommended a death sentence, and the trial court followed the
    jury’s recommendation and sentenced Thomas to death. The Alabama Court of
    Criminal Appeals and the Alabama Supreme Court affirmed Thomas’s conviction
    and death sentence. Thomas v. State, 
    539 So. 2d 375
     (Ala. Crim. App. 1988); Ex
    parte Thomas, 
    539 So. 2d 399
     (Ala. 1988). The United States Supreme Court
    denied certiorari review. Thomas v. Alabama, 
    491 U.S. 910
    , 
    109 S. Ct. 3201
    (1989).
    Thomas filed a state petition for post-conviction relief pursuant to Ala. R.
    Crim. P. 32, raising numerous claims for relief. With regard to Thomas’s claim
    that he was mentally retarded and exempt from execution under the Eighth and
    2
    Fourteenth Amendments, the trial court determined that the claim was
    procedurally defaulted under state rules because Thomas could have raised the
    claim at trial or on direct appeal but failed to do so. Alternatively, the trial court
    found that the claim had been raised and fully litigated at trial and on direct
    appeal; therefore, it was precluded from granting Thomas post-conviction relief
    under Ala. R. Crim. P. 32.2(a)(2) and (a)(4). The state trial court also held that
    Thomas was not in fact mentally retarded and rejected his claim. [State R. 42 at
    734–36.] With regard to Thomas’s other claims, the trial court denied relief, and
    after conducting an evidentiary hearing on Thomas’s claim that his trial counsel
    were ineffective for not investigating and developing evidence to support an
    insanity defense, denied Thomas post-conviction relief. The state appellate courts
    affirmed. See Thomas v. State, 
    766 So. 2d 860
     (Ala. Crim. App. 1998) (holding
    that Thomas’s Eighth Amendment claim was procedurally barred under state
    procedural rules and that as a matter of federal constitutional law, Thomas’s
    Eighth Amendment claim was without merit); Ex parte Thomas, 
    766 So. 2d 975
    (Ala. 2000).
    In March 2001, Thomas filed a federal habeas petition pursuant to 
    28 U.S.C. § 2254
     raising numerous challenges to his capital murder conviction and death
    sentence. The district court denied Thomas habeas relief with one exception—it
    3
    found that the state court’s post-conviction determination that Thomas was not
    mentally retarded was contrary to, and an unreasonable application of, clearly
    established federal law as determined by the Supreme Court in Atkins, as well as
    an unreasonable determination of the facts in light of the evidence presented in the
    state post-conviction court. [R. 86 at 250–54 (citing 
    28 U.S.C. § 2254
    (d)).]1
    Initially, the district court ordered that the case be remanded to state court for a re-
    evaluation of Thomas’s mental retardation claim, but later, upon a joint motion of
    the parties, the district court withdrew that portion of its order and scheduled a
    hearing on Thomas’s claim of mental retardation. After an Atkins hearing, the
    district court found Thomas to be mentally retarded and ordered that the
    Limestone County, Alabama, Circuit Court re-sentence him to a term of life
    imprisonment without the possibility of parole. The State appeals.
    II. ISSUE
    1
    Because the Atkins decision announced a “new rule of constitutional law made retroactive
    to cases on collateral review,” In re Holladay, 
    331 F.3d 1169
    , 1172 (11th Cir. 2003), the district
    court noted that Thomas’s Eighth Amendment claim that it would be cruel and unusual punishment
    to execute him because he is mentally retarded could not be defaulted under state procedural rules.
    Accordingly, the district court gave no deference to the state courts’ opinions to the contrary and
    reviewed the claim under the parameters set forth in the Anti-terrorism and Effective Death Penalty
    Act, 
    28 U.S.C. § 2254
     (2006). In this appeal, the State does not challenge the district court’s
    decision with respect to any procedural bar. Thus, any such challenge is deemed abandoned, and we
    consider the merits of the issue according no deference to any state court decision on this, or any
    tangentially-related, issue. See Holladay v. Allen, 
    555 F.3d 1346
    , 1348 n.1 (11th Cir. 2009).
    4
    Whether the district court clearly erred in finding Thomas mentally retarded
    and ineligible for execution under the Eighth Amendment.
    III. STANDARD OF REVIEW
    “We review the district court’s finding that [Thomas] is mentally retarded
    for clear error.” Holladay v. Allen, 
    555 F.3d 1346
    , 1353 (11th Cir. 2009) (citation
    omitted). “Clear error is a highly deferential standard of review.” Holton v. City
    of Thomasville Sch. Dist., 
    425 F.3d 1325
    , 1350 (11th Cir. 2005). “[A] finding is
    ‘clearly erroneous’ when although there is evidence to support it, the reviewing
    court on the entire evidence is left with the definite and firm conviction that a
    mistake has been committed.” Anderson v. City of Bessemer City, N.C., 
    470 U.S. 564
    , 573, 
    105 S. Ct. 1504
    , 1511 (1985) (quoting United States v. U. S. Gypsum
    Co., 
    333 U.S. 364
    , 395, 
    68 S. Ct. 525
    , 542 (1948)).
    IV. DISCUSSION
    A. Controlling Legal Criteria
    Unpersuaded that the execution of mentally retarded capital offenders
    would “measurably advance the deterrent or the retributive purpose of the death
    penalty,” the Atkins Court held that the execution of mentally retarded capital
    offenders violates the Eighth Amendment. 
    536 U.S. at 321
    , 
    122 S. Ct. at 2252
    .
    The Atkins majority agreed that mentally retarded individuals should be punished
    5
    when they commit crimes, but also recognized that the disabilities of such persons
    in the areas of reason, judgment, and impulse control diminish their ability to “act
    with the level of moral culpability that characterizes the most serious adult
    criminal conduct.” 
    Id. at 306
    , 
    122 S. Ct. at 2244
    . The Court noted that “clinical
    definitions of mental retardation require not only subaverage intellectual
    functioning, but also significant limitations in adaptive skills such as
    communication, self-care, and self-direction that became manifest before age 18.”
    
    Id. at 318
    , 
    122 S. Ct. at 2250
    . Because of these impairments, mentally retarded
    individuals “have diminished capacities to understand and process information, to
    communicate, to abstract from mistakes and learn from experience, to engage in
    logical reasoning, to control impulses, and to understand the reactions of others.”
    Id.,
    122 S. Ct. at 2250
    . Thus, the Court held that “death is not a suitable
    punishment for a mentally retarded criminal.” 
    Id. at 321
    , 
    122 S. Ct. at 2252
    .
    Although the Atkins Court alluded to clinical definitions propounded by the
    American Association on Mental Retardation (“AAMR”) and the American
    Psychiatric Association (“APA”), it left to the states the development of standards
    for courts to employ in making a determination of whether an offender is mentally
    retarded. 
    Id. at 317
    , 
    122 S. Ct. at 2250
    . Thus, we look to Alabama case law for
    guidance because the Alabama Legislature has not enacted any legislation
    6
    developing procedures by which a court may determine if a capital defendant is
    mentally retarded and thus ineligible for execution.
    The Alabama Supreme Court in Ex parte Perkins, 
    851 So. 2d 453
    , 456 (Ala.
    2002), held that a defendant alleging an Eighth Amendment mental retardation
    claim must show that he has significantly subaverage intellectual functioning (IQ
    of 70 or below), significant or substantial deficits in adaptive behavior, and that
    these problems manifested themselves during the developmental period (before
    the age of eighteen). Later, in Smith v. State, the Alabama Supreme Court added
    an additional element to the definition by stating that a defendant must exhibit
    significantly subaverage intellectual functioning abilities and significant deficits in
    adaptive behavior during three periods of his life: before the age of eighteen, on
    the date of the capital offense, and currently. ___ So. 2d ___, No. 1060427, 
    2007 WL 1519869
    , at *8 (Ala. May 25, 2007). “All three factors must be met in order
    for a person to be classified as mentally retarded for purposes of an Atkins claim.”
    Id.
    1. Standardized Assessment Instruments
    The two most widely recognized and utilized intellectual functioning
    assessment instruments are the Wechsler Adult Intelligence Scales (“WAIS”) and
    the Stanford-Binet Intelligence Scales (“SB"). The expert witnesses in this case
    7
    utilized these instruments, as well as others, to assess Thomas’s intellectual
    functioning.2 When considering an individual’s intellectual functioning test score,
    the evaluator may consider the Standard Error of Measurement (“SEM”), which is
    an index of the variability of test scores produced by persons forming the
    normative sample. In other words, the SEM is a statistical measure that allows the
    evaluator to know the amount of error that could be present in any test. The
    AAMR acknowledges that the SEM has been estimated to be three to five points
    for well-standardized measures of general intellectual functioning. Hence, the IQ
    standard score is bounded by a range that would be approximately three to four
    points above and below the obtained scores. [R. 130 at 20–31.] In Thomas’s case,
    the parties stipulated that a SEM of approximately plus or minus five points was
    proper for full-scale IQ test scores produced by the intelligence assessment
    instruments. [Id. at 24.]
    An evaluator may also consider the “Flynn effect,” a method that recognizes
    the fact that IQ test scores have been increasing over time. [Id. at 31–39.] The
    Flynn effect acknowledges that as an intelligence test ages, or moves farther from
    the date on which it was standardized, or normed, the mean score of the population
    2
    We rely on the district court’s very thorough explanation of these standardized assessment
    instruments and do not elaborate on them in this opinion. [R. 130 at 10–18.]
    8
    as a whole on that assessment instrument increases, thereby artificially inflating
    the IQ scores of individual test subjects. Therefore, the IQ test scores must be
    recalibrated to keep all test subjects on a level playing field. The parties in this
    case agree that the Flynn effect is an empirically proven statistical fact; however,
    they disagree on the extent to which an individual test subject’s IQ score should be
    adjusted to take into consideration this phenomenon. [Id. at 33.]
    a. Developmental Period
    The record indicates that Thomas’s first intellectual functioning evaluation
    occurred on October 4, 1968, when Thomas was nine years and seven months of
    age. Dr. David Loiry, Ph.D., a psychologist, administered a short form version of
    the Wechsler Intelligence Scales for Children (“WISC”). According to Dr. Loiry’s
    report, Thomas’s estimated full-scale IQ score of 56 placed him near the middle of
    the range of moderate mental deficiency according to the classification system
    utilized by the APA. [R. Pet’r Exh. 3 & 4.] Dr. Loiry recommended that Thomas
    be placed in a special class for the educable mentally retarded. [Id.]
    When Thomas was thirteen, he took the California Test of Mental Maturity,
    Short Form, along with other students. That test measured various aspects of
    intellectual functioning, such as memory and logical reasoning, at five different
    levels of difficulty. Thomas’s composite IQ score was 68. The third assessment
    9
    occurred in June 1973, when Thomas was fourteen years and two months of age.
    At the request of Dr. Frank M. Cauthen, M.D., Dr. Loiry administered four tests:
    the full WISC; the Wide Range Achievement Test; the Bender Visual Motor
    Gestalt Test; a figure drawing test; and a Rorschach test. Thomas’s full-scale IQ
    score on the WISC was 64, and his other test results were poor. Dr. Loiry
    concluded that there was no doubt about Thomas’s mental retardation. [Id.]
    Shortly after Thomas’s sixteenth birthday, Jim Lenz, a psychometrist for the
    Limestone County School System, administered the WAIS to Thomas to
    determine whether he should remain in special education classes. Thomas’s full-
    scale IQ score was 74, and Mr. Lenz concluded that Thomas was functioning in
    the educable range of mental retardation and should remain in special education
    classes. [R. Pet’r Exh. 6.]
    b. Post-developmental Period
    A month after Thomas’s eighteenth birthday, Joyce Raley, a counselor at the
    West Limestone School, administered a WAIS test to Thomas, and he scored his
    highest full-scale IQ score—77. Prior to the murder trial, when Thomas was
    twenty-six years old, Dr. K. Hall, a doctor at the Taylor Hardin Secure Medical
    Facility, administered the revised WAIS to Thomas, who had a full-scale IQ of 71.
    Dr. Hall concluded that Thomas was functioning within the borderline range of
    10
    intellect. Dr. James Crowder, Ph.D., a psychologist, also administered a revised
    WAIS to Thomas prior to trial, and Thomas’s full-scale IQ score was 65. In
    September 2007, in preparation for Thomas’s federal evidentiary hearing on his
    Atkins claim, Dr. Harry McClaren administered a WAIS-III intelligence
    assessment to Thomas, and he obtained a full-scale IQ score of 65. Dr. McClaren
    also administered a test to Thomas to determine if Thomas was malingering, but
    the test results did not suggest malingering. Dr. Karen Salekin also administered
    an intelligence assessment to Thomas prior to the federal evidentiary hearing. She
    performed an SB5 intelligence assessment which indicated a full-scale IQ score of
    62.
    2. Adaptive Behavior
    The AAMR defines the term “adaptive behavior” as the collection of
    conceptual, social, and practical skills that people learn in order to function in
    their everyday lives. [R. 130 at 42– 47.] See also Holladay, 
    555 F.3d at 1353
    . As
    we noted in Holladay, “significant or substantial deficits in adaptive behavior are
    defined as concurrent deficits or impairments in present adaptive functioning in at
    least two of the following skill areas: communication, self-care, home living,
    social/interpersonal skills, use of community resources, self-direction, functional
    academic skills, work, leisure, health and safety.” 
    Id. at 1353
     (internal quotation
    11
    marks omitted). Therefore, to satisfy this prong of the test for mental retardation,
    Thomas must show a deficiency in two of these listed areas. See 
    id.
    Because Thomas had no standardized adaptive behavior assessments during
    his developmental period, the parties reviewed Thomas’s public school records,
    his standardized test scores, his social worker’s case records, and interviewed
    people who were acquainted with Thomas during this period, such as family
    members and teachers.3 The district court also reviewed these documents and
    relied extensively on the testimony presented during the evidentiary hearing to
    find that Thomas showed, by a preponderance of the evidence, that he had
    significant deficits in adaptive functioning prior to age eighteen in five areas: (1)
    functional academics; (2) work; (3) social and interpersonal skills; (4) home
    living; and (5) self-direction. Additionally, there were no formal behavior
    assessments performed on Thomas on or about the date of the capital offense.
    Relying on the tests, records, and testimony from the hearing, the district court
    3
    Dr. Salekin stated that the APA did not require the use of standardized, adaptive-behavior
    assessment instruments prior to Thomas’s eighteenth birthday. She also testified that in 2002, it
    became a diagnostic requirement to test for adaptive functioning. Dr. Salekin commented that, in
    her opinion, adaptive functioning “is more important than getting your IQ score.” [R. 124 Vol. I at
    58.]
    12
    found that Thomas currently suffers substantial limitations in at least two adaptive
    behavioral skill areas: (1) social and interpersonal skills; and (2) self-direction.4
    In preparation for the evidentiary hearing, Dr. Salekin summarized the
    dysfunctional and poor environment in which Thomas lived during most of his
    developmental period. Dr. Salekin referenced the Department of Pensions and
    Securities (“DPS”) records that were replete with information indicating that
    social services had repeatedly deemed Thomas’s parents unfit. When Thomas was
    living in the home with his parents, he was exposed to his father’s alcoholism, his
    father’s criminal activity, and his father’s domestic violence toward his mother.
    The DPS records also contained information that on numerous occasions,
    Thomas’s family did not have adequate food, clothing, and shelter, and Thomas’s
    mother did not access appropriate medical services for the care and treatment of
    her children. In her report, Dr. Salekin noted that multiple informants stated that
    Thomas was heavily influenced by his father who taught him to steal and to
    engage in other illegal activities. [R. Dr. Salekin Report, Exh. 110 at 19-20.]
    4
    The district court noted that the State did not dispute Thomas’s assertion that he had proven
    that he presently has significant deficits in adaptive functioning. Accordingly, the district court
    determined that the State had abandoned any such challenge. However, in an abundance of caution,
    the district court considered the evidence of record in light of the legal and diagnostic standards and
    concluded that Thomas did presently show significant deficits in adaptive functioning in at least two
    areas: social/interpersonal skills and self-direction. [R. 130 at 122–25.] The State does not challenge
    this finding on appeal.
    13
    Even Dr. Marson recorded that Thomas’s father took him to bars and taught him
    how to strip cars and rob houses. [R. Dr. Marson Report, Exh. 111-1 at 4–5.]
    The DPS records also indicated that Thomas resided with his family from
    birth until the age of twelve, when the DPS removed him from the home and
    placed him in DPS protective custody as a result of his arrest for arson. The DPS
    placed him in three different foster homes. Thomas lived approximately one year
    at each of the first two foster homes. The third foster home, the farm of Mr. and
    Mrs. Wayne Ridgeway, was the most successful placement for Thomas. Thomas
    resided there with other special needs children of low cognitive ability. Thomas
    had daily chores on the farm, and he learned to drive a tractor. During this time,
    Thomas played baseball, did not use illegal drugs, did not get into trouble in
    school, and attended church. His placement with the Ridgeways ended when he
    turned eighteen. [R. Dr. Salekin Report, Exh. 110 at 20–21.]
    Dr. Salekin also noted in her report that Thomas’s older brother opined that
    Thomas could not have managed money or maintained a household. One of
    Thomas’s foster parent’s daughter informed Dr. Salekin that, based on her
    interaction with Thomas, he was not capable of taking care of all the things
    necessary to live independently. David Seibert, Thomas’s special education
    teacher, stated that Thomas would have a difficult time functioning independently
    14
    in a community setting because it would be hard for Thomas to keep up with
    budgeting his money and paying his bills. [Id. at 25–26.] Dr. Marson reported
    that Thomas had limited skills in dealing with finances and money. Thomas did
    not know how to keep an accurate record of funds, he never learned how to use a
    money order, and he never had any bills to pay. During the interview, Thomas had
    significant difficulty calculating simple math computations. [R. Dr. Marson
    Report, Exh. 111-1 at 12.]
    Three persons who had extensive contact with Thomas prior to age eighteen
    testified at the evidentiary hearing. Wayne Ridgeway, whose parents served as
    Thomas’s foster parents for several years, testified that he saw Thomas every day
    while Thomas lived on the farm. He stated that Thomas did not have girlfriends
    and did not socialize and do things that other boys his age did. Wayne commented
    that he could not leave Thomas unsupervised while performing a task, and he had
    to give Thomas directions “over and over.” [R. 124 Vol. I at 225–248.] He taught
    Thomas how to drive a tractor, but Thomas was the slowest of the 40 or more
    foster children he taught to drive a tractor. He opined that Thomas could not have
    lived independently.
    David Seibert, Thomas’s special education teacher in high school, stated
    that Thomas would not have been able to function well in a normal classroom, and
    15
    Thomas required much repetition in order to follow instructions. [R. 124 Vol. I at
    263–288.] Carole Russell, Thomas’s case worker from age twelve until eighteen,
    testified that Thomas was very immature, and his mannerisms were childlike. She
    thought he was very far behind both socially and educationally, and he had a poor
    ability to follow instructions. She also noted that Thomas not only lacked the
    maturity of children his same age, but he looked like a child much younger in age.
    [R. 124 Vol I at 289-125 Vol. II at 26.]
    B. Analysis
    The district court found that Thomas showed, by a preponderance of the
    evidence, that he suffers from significant limitations in intellectual functioning
    that originated before the age of eighteen years, were present on the date of the
    offense of conviction, and continue to the present day. The district court further
    found that Thomas showed, by a preponderance of the evidence, that his adaptive
    functioning abilities have been substantially impaired throughout his life,
    including the developmental period, the time surrounding the offense of
    conviction, and the present. As such, the district court found that Thomas is
    mentally retarded and is ineligible for execution because the imposition of the
    death penalty would violate the Eighth Amendment’s prohibition against cruel and
    unusual punishment. On appeal, the State challenges the district court’s findings
    16
    that Thomas showed limited intellectual functioning and limited adaptive
    functioning during the developmental period. The State proffers several specific
    challenges.
    1. Intellectual Assessment
    a. Failure to follow the IQ score of 70
    The State contends that the district court committed clear error when it did
    not adhere to Alabama precedent holding that an IQ score of 70 is the cutoff for
    significantly subaverage intellectual functioning. See, e.g., Smith, ___ So. 2d ___,
    
    2007 WL 1519869
    , at *8; Ex parte Perkins, 
    851 So. 2d at 456
    . The State argues
    that had the district court properly followed Alabama precedent, it would have
    found that Thomas did not have subaverage intellectual functioning during the
    developmental period because he had an IQ score of 77 when he was eighteen
    years old. Additionally, in support of its assertion, the State references Thomas’s
    increased scoring over the course of his developmental period.
    Contrary to the State’s contention, there is no Alabama precedent stating
    that when a capital offender has numerous IQ test scores during the developmental
    period, and one of those IQ scores is over 70, then the court cannot find the
    offender mentally retarded. The district court considered all of Thomas’s IQ
    scores from the developmental period— 56 at age nine, 68 at age thirteen, 64 at
    17
    age fourteen, and 77 at age eighteen (shortly after the end of the developmental
    period), and concluded that Thomas had proven, by a preponderance of the
    evidence, that he suffered subaverage intellectual functioning during his
    developmental period. Because one or more of these raw scores, excluding the
    post-eighteen age score, clearly indicate mental retardation, and the mean of these
    three scores fell below the 70 score cutoff, the district court did not clearly err in
    its finding. There is no Alabama case law stating that a single, or even multiple,
    raw IQ score above 70 automatically defeats an Atkins claim when the totality of
    the evidence (scores) indicates that a capital offender suffers subaverage
    intellectual functioning.
    b. Failure to consider the IQ score of 77
    The State argues that the district court’s decision not to consider Thomas’s
    highest IQ raw score of 77 is clearly erroneous. The State contends that this score
    was an accurate indication of Thomas’s upward trend in intellectual functioning.
    The argument is not compelling. Even considering the IQ raw score of 77, taken
    after the termination of Thomas’s developmental period, the mean of Thomas’s IQ
    scores during the developmental period is sufficiently below 70. See Holladay,
    
    555 F.3d at
    1357–58 (district court found significant limitations in intellectual
    functioning based on multiple IQ scores, the mean of which was below 70). Thus,
    18
    the district court did not err because, even considering this high score, Thomas
    still showed, by a preponderance of the evidence, that he had significant
    subaverage intellectual functioning during the developmental period.
    c. Application of Flynn effect
    The State takes issue with the district court’s employment of the Flynn
    effect. The question is not whether the district court’s application of the Flynn
    effect to lower Thomas’s IQ scores was mandatory, but whether the district court’s
    application of it in this case was clearly erroneous. We cannot say that it was.
    At the hearing, all the experts acknowledged that the Flynn effect is a
    statistically—proven phenomenon, although no medical association recognizes its
    validity. Numerous courts recognize the Flynn effect. See e.g., Walker v. True,
    
    399 F.3d 315
    , 322–23 (4th Cir. 2005) (stating that on remand, the district court
    should consider the Flynn effect evidence to determine if petitioner’s IQ score is
    overstated); United States v. Davis, 
    611 F. Supp. 2d 472
    , 486–88 (D. Md. 2009)
    (district court considered Flynn effect in evaluation of defendant’s intellectual
    functioning); People v. Superior Court, 
    28 Cal. Rptr. 3d 529
    , 558–59 (Cal. Ct.
    App. 2005), overruled on other grounds by 
    155 P.3d 259
     (Cal. 2007) (recognizing
    that Flynn effect must be considered); State v. Burke, No. 04AP-1234, 
    2005 WL 3557641
    , at *13 (Ohio Ct. App. Dec. 30, 2005) (stating that court must consider
    19
    evidence on Flynn effect, but it is within court’s discretion whether to include it as
    a factor in the IQ score). There are also courts that do not recognize the Flynn
    effect. See In re Mathis, 
    483 F.3d 395
    , 398 n.1 (5th Cir. 2007) (noting that circuit
    has not recognized Flynn effect as scientifically valid); Berry v. Epps, No.
    1:04CV328-D-D, 
    2006 WL 2865064
    , at *35 (N.D. Miss. Oct. 5, 2006) (refusing to
    consider Flynn effect); Bowling v. Commonwealth, 
    163 S.W.3d 361
    , 374–75 (Ky.
    2005) (noting that because Kentucky statute unambiguously sets IQ score of 70 as
    cutoff, courts cannot consider Flynn effect or SEM). Because there is no uniform
    consensus regarding the application of the Flynn effect in determining a capital
    offender’s intellectual functioning, and there is no Alabama precedent specifically
    discounting a court’s application of the Flynn effect, we cannot say that the district
    court clearly erred in applying it. The district court considered the Flynn effect
    just as it considered the other evidence in the record presented by the parties
    regarding Thomas’s intellectual functioning. Moreover, even without application
    of the Flynn effect, Thomas has still shown by a preponderance of the evidence
    that he has significantly subaverage intellectual functioning. Hence, we are not
    left with a definite and firm conviction that the district court erred in its finding.
    d. Application of SEM
    20
    The State also argues that the district court’s utilization of the SEM was
    clearly erroneous because the court did not consider it as a plus or minus five point
    range indicating a confidence level in the IQ scores; instead, the district court used
    it as a five point downward adjustment in Thomas’s IQ scores. Even if the district
    court improperly employed the SEM, it did not clearly err in its application. First,
    the parties stipulated at the hearing that the SEM was plus or minus five points.
    Second, Alabama courts have adopted the “most liberal definition of mental
    retardation employed by those states that bar the execution of the mentally
    retarded,” Burgess v. State, 
    962 So. 2d 272
    , 299 (Ala. Crim. App. 2005), and
    Alabama courts have acknowledged the application of the SEM. See Byrd v.
    State, ___ So. 3d ___, No. CR-07-0113, 
    2009 WL 1164985
    , at *3 (Ala. Crim.
    App. May 1, 2009) (noting that the psychologist testified that there is a 95%
    confidence interval regarding the capital offender’s IQ scores). Third, the district
    court adjusted Thomas’s scores downward based on its finding that Thomas had
    significant deficits in adaptive behavior. Fourth, in this case, five of the eight raw
    IQ scores for Thomas were below 70, and the district court adjusted his scores
    downward based on the preponderance of the evidence that indicated that the
    higher IQ scores may have been overstated. Lastly, even if the district court
    improperly applied the SEM, Thomas’s total mean raw IQ score was below 70, the
    21
    cutoff for intellectual functioning as stated by Alabama case law. In sum, the
    district court exercised its discretion to consider the SEM, as it did with the Flynn
    effect, and we cannot say that this was clear error.
    2. Adaptive Behavior
    The State takes issue with the district court’s finding that Thomas showed,
    by a preponderance of the evidence, that he had significant deficits in adaptive
    functioning before his eighteenth birthday. The district court relied upon records
    maintained by public schools, DPS social worker records, the recollections of
    persons who were acquainted with Thomas during his youth, the testimony of
    experts at the evidentiary hearing, and the reports of experts to conclude that
    Thomas had pronounced deficits in five areas: functional academics, work,
    social/interpersonal skills, home living, and self-direction. The record supports
    the district court’s findings, and the State cannot show that the district court
    clearly erred in its determination regarding Thomas’s adaptive behavior during the
    developmental period.
    David Siebert, Thomas’s high school special education teacher, testified that
    Thomas was definitely mentally retarded, that he could not follow complicated
    directions, and that he required repetition before he retained information. Drs.
    Salekin and Marson testified that Thomas could not have survived in a regular
    22
    classroom. Moreover, Thomas’s IQ scores during his developmental period
    placed him in the mildly mentally retarded range. Even the State’s expert, Dr.
    McClaren, stated that all of Thomas’s IQ scores prior to age eighteen are
    consistent with mental retardation. [R. 125 Vol. II at 238.] There is no clear error
    in the district court’s finding that Thomas had a pronounced deficit in functional
    academics during his developmental period.
    In challenging the district court’s finding that Thomas had pronounced
    deficits in the work area, the State contends that Thomas worked at a farm
    performing manual labor and driving a tractor and that Thomas held several other
    menial jobs. However, the experts testified that these skills are consistent with
    individuals with mild mental retardation. Even the State’s expert, Dr. McClaren,
    stated that mentally retarded persons can drive cars and hold menial jobs. Thus,
    the district court’s finding regarding Thomas’s work deficit is not clearly
    erroneous.
    The State claims that Thomas’s ability to manipulate people shows that he
    did not have substantial limits in his social/interpersonal skills. The State relies
    heavily upon the testimony of DPS social worker Carole Russell, who referenced
    an incident when Thomas, in the presence of his foster mother, told them he did
    not want to have contact with his biological mother, but when he was alone with
    23
    the case worker, told her that he did. The State also relies upon the testimony of
    Thomas’s teacher who stated that Thomas seemed to get along well with his
    fellow classmates and the record evidence that Thomas played baseball and spoke
    of enlisting in the Navy.
    The record indicates to the contrary. Wayne Ridgeway testified that
    Thomas did not have girlfriends and did not do things other boys his age did.
    Carole Russell also stated that Thomas was immature and socially behind his
    peers. Thus, contrary to the State’s assertion, we are not left with the definite and
    firm conviction that the district court erred in finding that Thomas suffered
    substantial limitations in his social and interpersonal skills during his
    developmental period.
    The State contends that the district court also clearly erred in finding that
    Thomas had limitations in his ability to live by himself and function
    independently. Again, the record is to the contrary. Dr. Marson testified that
    Thomas always needed an adult to assist him with his needs. Moreover, several
    witnesses testified that Thomas could neither live independently nor handle
    finances. The State’s attempt to challenge the district court’s finding regarding
    Thomas’s limitations in self-direction also fails. The record indicates that Thomas
    was immature both socially and mentally, that he required lots of repetition in
    24
    order to follow instructions, and that he could not live independently. The State
    cannot show that the district court’s finding that Thomas suffered substantial
    limitations in self-direction is clearly erroneous.
    V. CONCLUSION
    The district court conducted a comprehensive examination of the record
    evidence and assessed the credibility of the experts and acquaintances who
    testified at the Atkins evidentiary hearing. The district court wrote a very lengthy,
    detailed opinion finding that Thomas had shown by a preponderance of the
    evidence that he is mentally retarded and ineligible for execution. Having
    conducted a thorough review of the record, we cannot say that the district court’s
    finding is clearly erroneous. Accordingly, we affirm the district court’s grant of
    sentencing phase habeas relief to Thomas.
    AFFIRMED.
