    MOTION FOR REHEARING FILED:
    MANDATE ISSUED:
    EN BANC.
    LAMAR, JUSTICE, FOR THE COURT:
    ¶1.    The Eighth Amendment to the United States Constitution prohibits execution of
    persons who are intellectually disabled.1 Following a hearing, the Circuit Court of Quitman
    1
    The terms “intellectually disabled” and “intellectual disability” have replaced
    “mentally retarded” and “mental retardation” in the professional vernacular. Chase v. State,
    
    171 So. 3d 463
    , 466 n.1 (Miss. 2015) (“Chase V”). This Court uses the new terminology in
    opinions “except where a quotation necessitates use of the older terminology.” 
    Id. County found
    that death-row inmate Anthony Carr had failed to prove that he is within that
    category of persons. We reverse and remand for additional findings by the trial court.
    FACTS AND PROCEDURAL HISTORY
    ¶2.    Just before midnight on February 2, 1990, the Lambert Volunteer Fire Department
    responded to a call at Carl and Bobbie Jo Parker’s home. Carr v. State, 
    655 So. 2d 824
    , 830
    (Miss. 1995) (“Carr I”). Firemen found Carl and the Parkers’ children, twelve-year-old
    Gregory and nine-year-old Charlotte, dead inside. 
    Id. at 830.
    Carl and Gregory each had
    been shot twice. 
    Id. at 832.
    Their feet and ankles were bound, and their wrists were tied
    behind their backs. 
    Id. at 830.
    Charlotte had been shot three times, and a piece of binding
    was on her wrists. 
    Id. at 830,
    832. She was naked from the waist down under her dress, and
    there was evidence of sexual battery (both vaginally and anally). 
    Id. at 830.
    Bobbie Jo’s
    body was not found until after the fire was extinguished early the next morning. 
    Id. She was
    burned beyond recognition and had been shot once. 
    Id. at 830,
    832.
    ¶3.    Anthony Carr and Robert Simon Jr. were arrested the next day. 
    Id. at 831.
    After a
    nine-day trial, Carr was convicted on four counts of capital murder and sentenced to death
    for each. 
    Id. at 832.
    This Court affirmed his convictions and sentences in 1995. 
    Id. at 858.
    ¶4.    In 2004, this Court granted Carr leave to proceed in the circuit court on his post-
    conviction relief claim that he is intellectually disabled and thus ineligible for the death
    penalty under Atkins v. Virginia, 
    536 U.S. 304
    , 
    122 S. Ct. 2242
    , 
    153 L. Ed. 2d 335
    (2002).
    Carr v. State, 
    873 So. 2d 991
    (Miss. 2004) (“Carr II”). Following a hearing, the circuit
    court denied Carr’s petition.
    ¶5.    Carr now appeals, raising two issues, which we restate as:
    2
    I.     Is it unconstitutional for Carr to bear the burden of proof here,
    when the trial judge found that the question of his intellectual
    disability was “too close to call”?
    II.    Did the circuit court err in holding that Carr is not intellectually
    disabled?
    DISCUSSION
    ¶6.    Before turning to Carr’s arguments, we first address briefly the State’s argument that
    Carr’s appeal should be dismissed as untimely. The circuit court denied Carr’s petition on
    June 19, 2013. Carr moved for reconsideration under Rules 52(b) and 59(e) of the
    Mississippi Rules of Civil Procedure on July 2, 2013—one day after the ten-day deadline
    under those rules. The court denied reconsideration on March 3, 2014, and, eighty-one days
    later, on May 23, 2014, Carr filed an out-of-time notice of appeal.2
    ¶7.    First, there is no evidence in the record that the State objected or responded to Carr’s
    motion for reconsideration. So the State’s challenge to the timeliness of that motion is
    procedurally barred. Second, while we recognize that Carr’s appeal was untimely filed,
    “[w]e may suspend Rules 2 and 4 ‘when justice demands’ to allow an out-of-time appeal in
    criminal cases.” McGruder v. State, 
    886 So. 2d 1
    , 2 (Miss. 2003) (citing Fair v. State, 
    571 So. 2d 965
    , 966 (Miss. 1990)).3 We do so here, because the stakes are significant, and the
    issues merit review.
    2
    Carr says that he did not receive notice of the circuit court’s order denying
    reconsideration until May 22, 2014.
    3
    Post-conviction proceedings, of course, are civil actions. Miss. Code Ann. § 99-39-7
    (Rev. 2015). Yet they are subject to the same terms and conditions as criminal cases for the
    purposes of appeal. Miss. Code. Ann. § 99-39-25(1) (Rev. 2015).
    3
    I.     Is it unconstitutional for Carr to bear the burden of proof here,
    when the trial judge found that the question of his intellectual
    disability was “too close to call”?
    ¶8.    After hearing evidence from Carr and from the State, the trial judge found that the
    question of intellectual disability was “too close to call.” But because “[t]here cannot be a
    tie,” the burden of proof became the deciding factor, and the trial judge found that Carr had
    failed to meet his burden.
    ¶9.    Carr argues that he proved by a preponderance of the evidence that he is intellectually
    disabled. Without conceding that position, he also insists that, even if there was an
    evidentiary “tie,” the case still must be resolved in his favor. Otherwise, argues Carr, a
    miscarriage of justice will result because the State will one day execute a person who is just
    as likely as not intellectually disabled.
    ¶10.   To be clear, Carr is not asking this Court to alter the burden of proof in all Atkins
    cases. Rather, he argues that when the evidence of intellectual disability is an “actual
    tie”—as the trial judge found here—the State must then bear the risk of error because the
    possible injury to the petitioner (i.e., death) is far greater than the possible harm, if any, to
    the State. According to Carr, the social harm in executing someone who could be
    intellectually disabled, combined with the value that society places on individual liberty,
    requires the State to bear the risk. Moreover, argues Carr, imposing the risk of error on the
    State is consistent with the “heightened scrutiny” applied in death-penalty cases.
    ¶11.   The State argues first that this issue is procedurally barred because Carr failed to raise
    it before the circuit court. We agree. See, e.g., Evans v. State, 
    725 So. 2d 613
    , 632 (Miss.
    1997) (collecting authorities). Carr claims it was impossible for him to do so “until the
    4
    circuit court issued its order declaring the outcome of the hearing a tie.” But while that may
    be true, Carr could have raised the issue in his motion for reconsideration.
    ¶12.   Procedural bar notwithstanding, we find also that this claim lacks merit. As the State
    points out, the burden of proof in Atkins cases is well-settled.4 And simply put, neither the
    Eighth Amendment nor the Due Process Clause requires that the State bear the burden here.
    ¶13.   Carr’s argument could be interpreted two ways. On one hand, he seems to argue that
    allocating the burden of proof to him under these facts violates his substantive Eighth
    Amendment right against cruel and unusual punishment. But the United States Supreme
    Court has never held nor even implied that a burden of proof alone can “so wholly burden
    an Eighth Amendment right as to eviscerate or deny the right.” Hill v. Humphrey, 
    662 F.3d 1335
    , 1351 (11th Cir. 2011) (emphasis omitted); see also Hall v. Florida, 
    134 S. Ct. 1986
    ,
    2011, 
    188 L. Ed. 2d 1007
    (2014) (Alito, J., dissenting) (“As [the petitioner] concedes, the
    Eighth Amendment permits States to assign to a defendant the burden of establishing
    intellectual disability by at least a preponderance of the evidence.”).
    ¶14.   A second interpretation of Carr’s argument implicates due process rather than the
    Eighth Amendment. In effect, he argues that it is simply unfair to require petitioners to bear
    the burden of proof when the question of intellectual disability is “too close to call.” We note
    first that this argument is completely unsupported by any authority. A party either bears the
    4
    See, e.g., Dickerson v. State, 
    175 So. 3d 8
    , 23 (Miss. 2015); Brown v. State, 
    168 So. 3d
    884, 891 (Miss. 2015); Goodin v. State, 
    102 So. 3d 1102
    , 1116 (Miss. 2012); Thorson
    v. State, 
    76 So. 3d 667
    , 676 (Miss. 2011); King v. State, 
    23 So. 3d 1067
    , 1075 (Miss. 2009);
    Doss v. State, 
    19 So. 3d 690
    , 714-15 (Miss. 2009); Chase v. State, 
    873 So. 2d 1013
    , 1029
    (Miss. 2004).
    5
    burden of proof or it does not. Stated differently, the burden of proof is not somehow
    allocated once the evidence has been presented.
    ¶15.   And importantly, Atkins did not establish a burden of proof. Nor did it provide
    definitive procedural or substantive guides for determining who is intellectually disabled.
    Bobby v. Bies, 
    556 U.S. 825
    , 831, 
    129 S. Ct. 2145
    , 2150, 
    173 L. Ed. 2d 1173
    (2009). Instead,
    consistent with its approach to insanity in Ford v. Wainwright, 
    477 U.S. 399
    , 405, 416–17,
    
    106 S. Ct. 2595
    , 
    91 L. Ed. 2d 335
    (1986), the United States Supreme Court left “to the
    State[s] the task of developing appropriate ways to enforce the constitutional restriction upon
    [their] execution of sentences.” 
    Atkins, 536 U.S. at 317
    .
    ¶16.   States generally reserve the power to set burdens of proof unless their standard
    offends some fundamental principle of justice:
    [I]t is normally “within the power of the State to regulate procedures under
    which its laws are carried out, including the burden of producing evidence and
    the burden of persuasion,” and its decision in this regard is not subject to
    proscription under the Due Process Clause unless “it offends some principle
    of justice so rooted in the traditions and conscience of our people as to be
    ranked as fundamental.”
    Medina v. California, 
    505 U.S. 437
    , 445, 
    112 S. Ct. 2572
    , 2577, 
    120 L. Ed. 2d 353
    (1992)
    (quoting Patterson v. New York, 
    432 U.S. 197
    , 201–02, 
    97 S. Ct. 2319
    , 2322, 
    53 L. Ed. 2d 281
    (1977)). So when analyzing whether a burden of proof offends a “fundamental principle
    of justice,” courts must consider historical practice and whether the burden violates a
    recognized principle of “fundamental fairness” in its operation. 
    Medina, 505 U.S. at 446-48
    .
    But there is no historical prohibition on executing the intellectually disabled. Atkins was
    6
    based on society’s “evolving standards of decency,” not historical tradition. 
    Atkins, 536 U.S. at 321
    ; 
    Hill, 662 F.3d at 1350
    .
    ¶17.    And while some states have not expressly assigned a burden of proof in intellectual
    disability cases, “[a]ll of the states that have expressly assigned a burden of proof regarding
    mental retardation have assigned this burden to the defendant.” Peggy M. Tobolowsky,
    Atkins Aftermath: Identifying Mentally Retarded Offenders and Excluding Them from
    Execution, 30 J. Legis. 77, 118 (2003); see also 
    Hill, 662 F.3d at 1355
    ; State v. Jimenez, 
    188 N.J. 390
    , 402, 
    908 A.2d 181
    , 188 (2006); opinion clarified, 
    191 N.J. 453
    , 
    924 A.2d 513
    (2007). Simply put, the Constitution does not require that the State bear the burden of proof
    in intellectual disability cases. United States v. Webster, 
    421 F.3d 308
    , 311 (5th Cir. 2005).
    ¶18.    Finally, Carr has cited no authority to support his assertion that the burden of proof
    should shift to the State when a case is close. It is telling that Carr cites a veteran’s-disability
    case to support the standard he advances. As the Eleventh Circuit Court of Appeals said in
    Hill:
    A third critical flaw in Hill’s argument is that a risk of error exists with any
    burden of proof. Every standard of proof allocates some risk of an erroneous
    factual determination to the defendant and therefore presents some risk that
    mentally retarded offenders will be executed in violation of Atkins . . . .
    The necessary result of Hill’s reasoning is that the burden of proof must be
    placed on the state and that the state must prove beyond any doubt that an
    offender is not mentally retarded. No state uses that standard. The effective
    result of Hill’s argument, then, is that every state’s death penalty statute or
    case law procedure is unconstitutional because none of them requires the state
    to prove the absence of mental retardation beyond a reasonable doubt. Or, to
    take Hill’s argument to its logical conclusion, beyond all doubt . . . .
    Hill, 
    662 F.3d 1335
    , 1355-56 (emphasis added).
    7
    ¶19.   In sum, we find that Carr’s burden-of-proof argument lacks merit. The difficulty in
    ascertaining where the truth lies may be a reason for placing the burden of proof on the
    proponent of an issue. Cooper v. Oklahoma, 
    517 U.S. 348
    , 366, 
    116 S. Ct. 1373
    , 1384, 
    134 L. Ed. 2d 498
    (1996). The effect of Carr’s proposal would be to prohibit the execution of
    anyone who is even arguably intellectually disabled. Neither the Eighth Amendment nor the
    Due Process Clause require such a rule.
    ¶20.   So having determined that Carr’s burden of proof is not unconstitutional, we turn now
    to his second issue on appeal and the evidence presented to the circuit judge.
    II.    Did the circuit court err in holding that Carr is not intellectually
    disabled?
    A.      Intellectual disability requires significantly subaverage
    intellectual functioning, significant deficits in adaptive behavior,
    and manifestation of both before age eighteen.
    ¶21.   In Chase v. State, this Court “recognize[d] developments in the field of assessing
    intellectual disability that have manifested since Atkins and Chase.” Chase v. State, 
    171 So. 3d
    463, 469 (Miss. 2015) (“Chase V”). This Court noted that, in 2004, it had adopted the
    American Association on Mental Retardation’s (AAMR) and the American Psychiatric
    Association’s (APA) definitions of intellectual disability cited in Atkins. 
    Id. at 471.
    This
    Court then took the opportunity to “adopt the 2010 AAIDD and 2013 APA definitions of
    intellectual disability as appropriate for use to determine intellectual disability in the courts
    of this state in addition to the definitions promulgated in Atkins and Chase.” 
    Id. ¶22. The
    American Association on Intellectual and Developmental Disability (formerly the
    AAMR) defines intellectual disability as a condition originating before age eighteen
    8
    “characterized by significant limitations in both intellectual functioning and in adaptive
    behavior as expressed in conceptual, social, and practical adaptive skills.” 
    Id. at 469
    (citations omitted). Significant deficits in one of the three adaptive-functioning domains are
    required:
    The conceptual skills domain includes “language; reading and writing; and
    money, time, and number concepts.” The social skills domain includes
    “interpersonal skills, social responsibility, self-esteem, gullibility, naivete (i.e.,
    wariness), follows rules/obeys laws, avoids being victimized, and social
    problem solving.” The practical skills domain includes “activities of daily
    living (personal care), occupational skills, use of money, safety, health care,
    travel/transportation, schedules/routines, and use of the telephone.
    Chase V, 
    171 So. 3d
    at 469 (internal citations omitted).
    ¶23.   And the APA defines intellectual disability as “a disorder with onset during the
    developmental period that includes both intellectual and adaptive functioning deficits in
    conceptual, social, and practical domains.” 
    Id. (citations omitted).
    Individuals must have
    significant deficits in one of the three domains:
    The conceptual (academic) domain involves competence in memory,
    language, reading, writing, math reasoning, acquisition of practical knowledge,
    problems solving, and judgment in novel situations, among others. The social
    domain involves awareness of others’ thoughts, feelings, and experiences;
    empathy; interpersonal communication skills; friendship abilities; and social
    judgment, among others. The practical domain involves learning and
    self-management across life settings, including personal care, job
    responsibilities, money management, recreation, self-management of behavior,
    and school and work task organization, among others.
    
    Id. at 469
    –70.
    ¶24.   Ultimately though, the exact wording of the above standards “makes little substantive
    difference.” 
    Id. at 470.
    All are similar and require the same three basic elements:
    “significantly subaverage intellectual functioning, significant deficits in adaptive behavior,
    9
    and manifestation before age eighteen.” 
    Id. An assessment
    of intellectual disability must be
    retrospective to the time of the crime and before the petitioner turned eighteen. 
    Id. at 468
    (citing 
    Goodin, 102 So. 3d at 1115
    ).
    ¶25.   Recently, in Hall v. Florida, the United States Supreme Court analyzed Florida’s
    capital sentencing scheme as it pertains to intellectually disabled persons. Hall v. Florida,
    
    134 S. Ct. 1986
    , 
    188 L. Ed. 2d 1007
    (2014). Florida’s Supreme Court had interpreted
    Florida’s statute very strictly, such that a person whose IQ test score is above 70—including
    a score within the margin of error5—“does not have an intellectual disability and is barred
    from presenting other evidence that would show his faculties are limited.” 
    Id. at 1994
    (emphasis added).
    ¶26.   In finding that interpretation unconstitutional, the United States Supreme Court said
    Florida’s rule disregards established medical practice in two interrelated ways.
    It takes an IQ score as final and conclusive evidence of a defendant’s
    intellectual capacity, when experts in the field would consider other evidence.
    It also relies on a purportedly scientific measurement of the defendant’s
    abilities, his IQ score, while refusing to recognize that the score is, on its own
    terms, imprecise.
    ....
    Intellectual disability is a condition, not a number. Courts must recognize, as
    does the medical community, that the IQ test is imprecise. This is not to say
    that an IQ test score is unhelpful. It is of considerable significance, as the
    medical community recognizes. But in using these scores to assess a
    defendant’s eligibility for the death penalty, a State must afford these test
    scores the same studied skepticism that those who design and use the tests do,
    5
    “Each IQ test has a ‘standard error of measurement’ . . . often referred to by the
    abbreviation ‘SEM.’” 
    Hall, 134 S. Ct. at 1995
    . “A score of 71, for instance, is generally
    considered to reflect a range between 66 and 76 with 95% confidence and a range of 68.5
    and 73.5 with a 68% confidence. See DSM–5, at 37 (‘Individuals with intellectual disability
    have scores of approximately two standard deviations or more below the population mean,
    including a margin for measurement error (generally +5 points) . . . .[T]his involves a score
    of 65–75 (70 ± 5)’).” 
    Id. 10 and
    understand that an IQ test score represents a range rather than a fixed
    number. A State that ignores the inherent imprecision of these tests risks
    executing a person who suffers from intellectual disability.
    This Court agrees with the medical experts that when a defendant’s IQ test
    score falls within the test’s acknowledged and inherent margin of error, the
    defendant must be able to present additional evidence of intellectual disability,
    including testimony regarding adaptive deficits.
    It is not sound to view a single factor as dispositive of a conjunctive and
    interrelated assessment. See DSM–5, at 37 (“[A] person with an IQ score
    above 70 may have such severe adaptive behavior problems . . . . that the
    person’s actual functioning is comparable to that of individuals with a lower
    IQ score”).
    ....
    By failing to take into account the standard error of measurement, Florida’s
    law not only contradicts the test’s own design but also bars an essential part of
    a sentencing court’s inquiry into adaptive functioning. Freddie Lee Hall may
    or may not be intellectually disabled, but the law requires that he have the
    opportunity to present evidence of his intellectual disability, including deficits
    in adaptive functioning over his lifetime.
    
    Id. at 1995;
    2001 (citations omitted) (emphasis added).
    B.     Pre-Hearing Assessment by the Mississippi State Hospital.
    ¶27.   In 2009, Drs. Gilbert S. Macvaugh III and Reb McMichael and their team at the
    Mississippi State Hospital evaluated forty-four-year-old Carr. Carr’s expert, Dr. C. Gerald
    O’Brien, did not interview Carr or assess him personally, but he relied on the State Hospital
    team’s assessment when forming his opinion about Carr’s intellectual functioning.
    ¶28.   To assess Carr’s intellectual functioning, the team considered three intelligence tests.
    The earliest took place in 1990 in the context of a pretrial forensic mental evaluation. Dr.
    William M. Kallman administered then-twenty-five-year-old Carr the Wechsler Adult
    11
    Intelligence Scale–Revised (WAIS–R).6 Carr’s full-scale intelligence quotient (IQ) score
    was 70, putting him in “the mildly mentally retarded range.” Dr. Kallman did not administer
    a test for malingering. He noted that Carr “may have exaggerated his psychological distress
    somewhat,” but considered the evaluation a “valid indicator” of Carr’s cognitive functioning
    and saw “no signs of malingering or intentional efforts to distort the data.”
    ¶29.   The State Hospital team administered two intelligence tests: the Wechsler Adult
    Intelligence Scale–Fourth Edition (WAIS–IV) and the Stanford-Binet Intelligence Scales,
    Fifth Edition (SB–5). Carr’s full-scale IQ score on the WAIS–IV was 72. Given test error,
    there was a ninety-five-percent chance that his “true” full-scale IQ score fell between 68 and
    77. He scored 70 on Verbal Comprehension, 75 on Perceptual Reasoning, 89 on Working
    Memory, and 79 on Processing Speed.
    ¶30.   On the SB–5, Carr’s full-scale IQ score was 75. Given test error, there was a ninety-
    five-percent chance that his “true” full-scale IQ score was between 72 and 80. He scored 71
    on Fluid Reasoning, 72 on Knowledge, 81 on Quantitative Reasoning, 82 on Visual Spatial,
    and 89 on Working Memory.
    ¶31.   The State Hospital team also administered two tests for malingering, the Rey 15-Item
    Memory Test and the Test of Memory Malingering (TOMM), and neither test suggested that
    Carr was malingering. Based on Carr’s test behavior and his performance on the malingering
    measures, the State Hospital team considered the WAIS–IV and SB–5 scores to be “valid
    estimates of his true intellectual ability.”
    6
    But the raw data from this testing was not available for review by the State Hospital
    team or by Dr. O’Brien.
    12
    ¶32.   In terms of intellectual functioning, the State Hospital team concluded that Carr was
    “at worst, functioning in the upper portion of the mild range of mental retardation; or at best,
    the lower portion of the borderline range of intellectual ability”:
    When considering the consistency in . . . Carr’s Full Scale IQ scores over time
    and across different instruments (i.e., WAIS–R = 70, WAIS–IV= 72; SB–5 =
    75), this seems to suggest that he is likely functioning in the low borderline
    range of intellectual ability. However, because of the error associated with all
    intelligence tests (plus or minus five points), and because IQ scores become
    artificially inflated over time (Flynn Effect), Mr. Carr’s IQ scores on the tests
    that we administered to him do not necessarily rule out the possibility of the
    diagnosis of mild mental retardation.
    For adaptive deficits, the State Hospital team said Carr “may have demonstrated significant
    limitations in at least two areas of adaptive behavior before the age of 18 (i.e., functional
    academics and work).”
    ¶33.   Evidence regarding functional academics conflicted. On one hand, school records
    showed that Carr had failed third, seventh, and ninth grades. He dropped out after his second
    attempt at ninth grade. And his grades were always “quite poor,” ranging from failing to
    barely passing. On the other hand, Carr’s absences were excessive, as he missed from
    twenty-five to forty-seven days each year.
    ¶34.   Despite Carr’s excessive absences, achievement-test data suggested he “probably
    demonstrated adaptive behavior deficits in the area of functional academics prior to the age
    of 18.” His eighth-grade achievement-test scores ranged from first to thirty-sixth percentile.
    He scored similarly on achievement testing done by Dr. Kallman in 1990, achieving third-
    and fourth-grade levels in reading, spelling, and math.
    13
    ¶35.   The State Hospital team could not determine if Carr had adaptive deficits in the area
    of employment. His work history was contradictory and inconsistent. The State Hospital
    team also noted limited, inconsistent information concerning Carr’s adaptive functioning in
    the community before his arrest at age twenty-five. Family members who were interviewed
    all described Carr as having both intellectual and adaptive behavior deficits. But the State
    Hospital team noted in its report that “concerns exist with regard to the reliability of the
    information obtained from these family members.”7
    ¶36.   The State Hospital team interviewed one of Carr’s former teachers, Cedonia Hunt, and
    included information from her in its report:
    Hunt reported that she taught Mr. Carr “sometime in the late 70’s.” She taught
    him in both “fifth and the sixth grades.” She also stated that he was in her
    “homeroom” in grade six. She is currently 63 years of age and has been retired
    as a schoolteacher for the last fourteen years.
    Asked how well she remembered Mr. Carr, she replied, “Pretty well.” Asked
    if she had ever worked with students diagnosed with mental retardation, she
    replied, “Yeah.” She then noted, “I don’t think he was mentally retarded . . .
    he was slow but not retarded.”
    Asked what type of student Mr. Carr was in her classes, she replied, “Poor.”
    Asked what was this cause for this, she replied, “Home environment and
    basically didn’t want to do it. . . [.] I felt he could do better.” Asked if he got
    into trouble during his school years, she replied, “As far as I can remember,
    yeah, fights and not paying attention.” Asked if he missed a lot of school, she
    replied, “A lot, made D’s in most subjects but because of his age, we decided
    to move him on because smaller children he would be with.” Asked if he was
    ever in any kind of Special Education classes, she replied, “Not that I know of
    . . . I always knew that he could have done better . . . it was the environment,
    the people he was around.”
    7
    Dr. Macvaugh noted during his testimony that family members “may have far more
    influence or pressure to sway the direction of their descriptions in one way or the other,” and
    that his “index of scepticism is increased” when determining their reliability.
    14
    Asked if she thought he had mental retardation, she replied, “I don’t think he
    was . . . he might have had a learning disability.” Asked if Special Education
    services were available for students at that time in that school, she replied,
    “Yes.”
    The State Hospital team considered Hunt’s reliability to be good.
    ¶37.   After considering all the information compiled in its fifty-eight-page report, the State
    Hospital team could not “offer an opinion to a reasonable degree of psychological and
    psychiatric certainty.” It summarized its assessment as follows:
    In summary, Mr. Carr does, in our opinion, have intellectual limitations and
    may very well have met the diagnostic criteria for mental retardation before the
    age of 18. However, we cannot be certain of this because he never received
    intelligence testing or a standardized assessment of his adaptive functioning
    before age 18. The only known prior intelligence testing was administered to
    him by Dr. Kallman within the context of a pre-trial forensic evaluation
    following his arrest at the age of 25. Dr. Kallman’s evaluation suggested that
    Mr. Carr may have been exaggerating symptoms of mental illness at the time
    but did not include an assessment of whether or not he may also have been
    fabricating or exaggerating intellectual deficits at that time as well.
    During our evaluation of him, Mr. Carr scored slightly higher on the
    intelligence testing that we administered to him, suggesting that he is likely
    functioning in the borderline range of intelligence, as opposed to the mildly
    mentally retarded range. Similarly, on the achievement testing that we
    administered to him, Mr. Carr scored somewhat better compared to his
    achievement test scores when administered similar testing in 1990 by Dr.
    Kallman, which suggests that Mr. Carr’s functional academic abilities are not
    currently impaired to the extent that Dr. Kallman described during his
    evaluation of Mr. Carr nearly 20 years ago.
    According to all of the professional definitions of, and formal diagnostic
    criteria for, the diagnosis of mental retardation, there must be evidence of
    manifestation of the disability during the developmental period (i.e., onset
    before the age of 18). Also according to the professional definitions, a person
    with mental retardation may, over time and with proper supports, improve in
    his or her functioning to the point that they no longer meet the diagnostic
    criteria for the disability. It is difficult to determine in Mr. Carr’s case whether
    or not his functioning prior to the age of 18 actually indicated that he had
    mental retardation. There were some data to suggest that had he been properly
    15
    evaluated for this, he may have received a diagnosis of mental retardation at
    that time. There also were some data to suggest that he may not have qualified
    for this diagnosis before the age of 18. Because of these contradictory data,
    we are unable to state definitively a retrospective opinion to a reasonable
    degree of psychological and psychiatric certainty that Mr. Carr was not
    mentally retarded before the age of 18.
    In our opinion, Mr. Carr did not appear to be mentally retarded at the time of
    our evaluation of him. However, our assessment of his more recent
    functioning, particularly his adaptive behavior over the course of his adult
    years while on death row, is confounded by how well he appears to function
    within the structure of a prison environment. Moreover, how well a person
    functions in prison is a poor index of what his actual level of functioning may
    be in the community, which is more relevant for making a diagnosis of mental
    retardation.
    C. The circuit court heard conflicting evidence at the hearing.
    ¶38.   Three witnesses testified at the Atkins hearing: former neighbor Johnie Chaney and
    Dr. O’Brien for Carr, and Dr. Macvaugh for the State.
    ¶39.   At age fourteen, Chaney moved into a house near Carr’s. Chaney could not recall
    Carr’s age at that time and conceded that Carr was possibly older than eighteen. The two
    knew each other and played games and sports together, including basketball and softball. In
    softball, Carr played in the outfield and did well at that position. “I told him to run and catch
    [the ball],” Chaney said, and Carr did so after receiving Chaney’s instruction.
    ¶40.   Chaney described Carr as a “follower” and said Carr had personal hygiene problems
    on occasion. “[Carr] came around me a couple of times and he had a odor to him,” and
    Chaney would tell Carr to “freshen up.” Chaney also helped Carr with his clothes and shoes.
    “I used to help [Carr], you know, keep his clothes right on him and tell him about his shoes.
    He would leave his shoes and things all untied, you know, stuff like that,” Chaney explained.
    16
    ¶41.   Dr. O’Brien found to a reasonable degree of certainty that Carr was intellectually
    disabled. Dr. O’Brien reviewed the same data as the State Hospital team, plus Carr’s fourth-
    and fifth-grade-level scoring on the Woodcock-Johnson III achievement test administered
    by Dr. Victoria Swanson in 2010. But Dr. O’Brien neither tested Carr nor evaluated him, nor
    did he interview any collateral sources. A paralegal in his office did follow-up interviews
    with a couple of collateral sources.
    ¶42.   Dr. O’Brien found that Carr met the intellectual-deficit criterion based on the “ability
    testing” done by Dr. Kallman and the State Hospital team, which Dr. Swanson’s testing
    corroborated. “[O]rdinarily an IQ score up to 75 is considered significantly subaverage,” Dr.
    O’Brien said. He did not question the validity of Dr. Kallman’s testing, but he did have some
    concern about not having Dr. Kallman’s raw test data. He said he did not like relying on
    intelligence tests without having such data, but he chose to take Dr. Kallman’s testing as
    reported because the data simply was unavailable.
    ¶43.   On cross-examination, the State questioned Dr. O’Brien about why his report had
    omitted Carr’s 89 Working Memory and 79 Processing Speed Index Scores on the WAIS–IV.
    Dr. O’Brien said he omitted those scores because he had no prior testing with which to
    compare them. “The only things I included in my little chart were those that could be at least
    roughly compared with previous tests results,” he explained. In his view, the 79 Processing
    Speed Index Score was “not particularly significant.” Yet he acknowledged that the 89
    Working Memory Index Score “could be” contraindicative of intellectual disability.
    ¶44.   For adaptive deficits, Dr. O’Brien conducted a retrospective analysis and found
    deficits in all three domains (conceptual, social, and practical) and in eight of the ten skill
    17
    areas (communication; functional academics; self-direction; leisure; social skills; home
    living; health and safety; and self-care).
    ¶45.     In considering onset before age eighteen, Dr. O’Brien relied primarily on Carr’s
    school records and Hunt’s statements corroborating that Carr had performed poorly in school.
    Carr failed three grades and, according to Hunt, was moved from sixth to seventh grade only
    because of his size. While acknowledging that Carr’s absences could have contributed to his
    poor performance, Dr. O’Brien did not give that factor much weight.8 In Dr. O’Brien’s view,
    school records reflect that Carr began reaching his peak academic potential by about the third
    grade.
    ¶46.     Dr. O’Brien did not see Carr’s lack of placement in special education as significant.
    Though Hunt said special-education services were available, Dr. O’Brien’s research showed
    that was unlikely based on the laws in effect at that time. He also questioned Hunt’s
    memory: she said she had taught Carr in fifth and sixth grades, but records showed she taught
    him in sixth grade only. Regardless, Dr. O’Brien saw Carr’s actual performance in school
    (which was poor) as more important than whether or not Carr was in special-education
    classes.
    ¶47.     Dr. O’Brien also discounted Hunt’s opinion that Carr might have had a learning
    disability as opposed to being intellectually disabled. A learning disability, Dr. O’Brien
    explained, implies a deficiency in one or two subjects. But Carr’s scores or grades all were
    8
    He explained his rationale for that as follows: First, Carr missed approximately the
    same number of days in first and second grades as he did in other years; yet he performed
    better in those first two grades. Second, Carr performed slightly better when he repeated
    third grade despite missing approximately the same number of days as he did in his first
    attempt at that grade.
    18
    low. Moreover, diagnosis of a learning disability requires formal testing. Dr. O’Brien
    testified further that Carr’s achievement-test scores showed “significantly subaverage
    performance.” In eighth grade, at age fifteen, Carr scored in the tenth percentile on the
    California Achievement Test. Dr. O’Brien noted that Carr’s thirty-sixth-percentile score in
    Spelling on that test was “amazingly high” given his scores in other areas. Dr. O’Brien
    viewed that score and Carr’s thirty-fourth-percentile score in Math Computation as outliers.
    ¶48.   The State challenged Dr. O’Brien about his failure to include any information in his
    report that was contrary to his opinion. Dr. O’Brien replied that his report was designed to
    be brief and that, in his view, the conflicting data was unsubstantial and did not merit
    mention:
    I don’t believe there are significant warnings and cautions that should [have
    been included]. I believe there are a number of items within the test data, for
    example, that are not particularly consistent. However, they are not substantial
    and significant. There are dozens and dozens of scores that are essentially
    consistent with his level of functioning as we’ve talked about it. There are a
    handful that aren’t. I don’t think the handful warrants me making a note in this
    report.
    ¶49.   While conceding that Carr has intellectual limitations, Dr. Macvaugh was unable to
    offer an opinion to a reasonable degree of psychological certainty that Carr is intellectually
    disabled. Dr. Macvaugh, testified that “[t]here are data, in my opinion, that suggest that Mr.
    Carr might have mental retardation, and there are data to suggest he might not.”
    ¶50.   In Dr. Macvaugh’s opinion, Carr does not currently satisfy the intellectual-deficit
    criterion. At the same time, he could not rule out the possibility:
    We had conflicting data as to the intellectual impairment prong. Based on our
    test in August of 2009, he scored a little north of where someone with mild
    [intellectual disability] would ordinarily score. However, considering test
    19
    error, the Flynn [E]ffect, the other issues . . . that could potentially affect the
    validity of test scores, it’s possible that he might be in that range that’s
    consistent. He is in that zone of ambiguity.
    Dr. Macvaugh testified that Carr was “essentially in that what we call the zone of ambiguity
    with these IQ test scores. They’re all fairly close and fairly consistent. They’re all
    technically at or above the cutoff.” Dr. Macvaugh also said that Carr’s tests were within the
    margin of error.
    ¶51.   Dr. Macvaugh interpreted the 89 Working Memory and 79 Processing Speed Index
    Scores on the WAIS–IV differently than Dr. O’Brien. In his opinion, both scores were
    inconsistent with intellectual disability. Dr. Macvaugh also found Carr’s score of seven on
    Arithmetic within the Working Memory Index Score to be “significant.” Further, Dr.
    Macvaugh said that Carr’s 81 in Quantitative Reasoning (tenth percentile), 82 in Visual
    Spatial (twelfth percentile), and 89 in Working Memory (twenty-third percentile) were
    “noteworthy.”
    ¶52.   This data left Dr. Macvaugh unable to form an opinion to a reasonable degree of
    confidence as to whether Carr had intellectual deficits before age eighteen. Dr. Macvaugh
    saw Dr. Kallman’s testing as pivotal:
    If that [IQ] score is valid, the 70 from Dr. Kallman from 1990, [Carr] is
    certainly within range. Excluding a discussion of error. But I don’t know that
    it’s valid. And that’s the closest score in terms of the nexus between the
    developmental onset criterion for the diagnosis. There has to be evidence that
    the disability manifests itself before the age of 18. He was 25 when he took the
    test. If it’s valid, those are the best IQ data we’ve got in terms of confirming
    the presence of the disorder during the developmental period, in terms of the
    onset. But, again, I can’t confirm that.
    20
    Unlike Dr. O’Brien, Dr. Macvaugh saw raw data as “paramount.” “[T]here could be gross
    flaws in the scoring or in the administration of the test that make the scores completely
    useless,” he explained. In addition to the lack of raw data, Dr. Kallman did not administer
    a malingering test.
    ¶53.   For adaptive functioning, Dr. Macvaugh reviewed school and Mississippi Department
    of Corrections records and interviewed collateral sources. Contrary to Dr. O’Brien, he
    believed that Carr’s thirty-fourth and thirty-sixth percentile scores in Math Computation and
    Spelling, respectively, were both inconsistent with intellectual disability. And even though
    Carr’s grades consistently were failing or near failing, the fact that Carr reached eighth grade
    was significant:
    In my experience that is rare [for someone who is intellectually disabled to
    even be in the eighth grade]. Usually folks that have mild mental retardation
    achieve at about or up to the sixth grade level. They are often in special
    education; not always, for some of the reasons that Dr. O’Brien was asked
    about. My understanding and my experience, however, is that it is very
    uncommon for somebody who has mental retardation or intellectual disability,
    to make it to the eighth grade and obtain certain achievement test scores with
    national percentile rankings this high if they had mental retardation. Those
    factors together would be unlikely, in my opinion. Is it possible? Sure. Is it
    probable? Probably not.
    Dr. Macvaugh also saw Hunt as a credible, reliable source.
    ¶54.   Dr. Macvaugh was noncommittal as to whether Carr’s nonplacement in special
    education showed that Carr was not intellectually disabled. On one hand, he believed it
    would be “very difficult” for someone who is intellectually disabled to make it to ninth grade
    without special education. Further, some of Carr’s achievement-test scores raised doubts as
    to whether Carr would have been eligible for special education. At the same time, Dr.
    21
    Macvaugh said other factors could have kept Carr from being placed in special education.
    Schools sometimes refrain from identifying intellectual impairments because of social
    stigma, political pressures, economics, racial issues, and over-identification biases. Like Dr.
    O’Brien, Dr. Macvaugh did not attribute much weight to Carr’s excessive absences. On one
    hand, he said it is hard to learn if you do not attend. But people with intellectual disabilities
    often miss school for that very reason: they are embarrassed about their underperformance.
    ¶55.   In assessing adaptive deficits, Dr. Macvaugh could not form a definitive opinion. “In
    my opinion, the possible areas of adaptive deficits that we had concerns about . . . consisted
    of functional academics and employment history. Those were two that [Carr] could possibly
    have. But the data, again, were contradictory, inconsistent, and didn’t fall squarely in one
    direction or the other.”
    ¶56.   Finally, Dr. Macvaugh was critical of Dr. O’Brien’s methodology. Dr. Macvaugh said
    he would not have proceeded as Dr. O’Brien did—without testing or evaluating Carr, or
    personally interviewing collateral sources. “I don’t think I have ever seen a forensic
    psychologist offer a definitive opinion, to a reasonable degree of psychological certainty,
    without personally evaluating the defendant, without personally collecting the data,” Dr.
    Macvaugh said. He also believed that forensic and ethical guidelines require all data—both
    supportive and nonsupportive of the expert’s opinion—to be included in a report.
    D.      The circuit judge found that Carr had failed to prove
    significantly subaverage intellectual functioning.
    22
    ¶57.   After hearing all of the evidence detailed above, the circuit judge issued an order
    denying Carr’s petition. After detailing the various IQ tests administered and the expert’s
    testimony about the tests, the trial judge concluded
    It can be said comfortably that Carr’s IQ, as demonstrated by the tests which
    were given, falls somewhere in the 70 to 75 range. Given the applicable and
    conceded margin [of] error of five (5) points either way which is applicable to
    such test[s], Carr’s actual IQ could range anywhere from a low of 65 to a high
    of 80. Obviously the lower the IQ, the more mental retardation is suggested.
    The higher the IQ, the less mental retardation is suggested. This is the inherent
    flaw in attempting to come to a concrete conclusion regarding a particular
    subject when the means for doing so relies on a margin of error. Certainly,
    Carr’s intelligence level is at the lower end of the spectrum, but is it
    significantly sub-average? Given the range within which the test results are
    found and the applicable margin of error, this court cannot find by a
    preponderance of the evidence that Carr has carried his burden of proof.
    While this finding alone is sufficient to deny Carr’s claim of mental
    retardation, because of the significance of this decision, the court will
    consider the other two remaining factors.
    (Emphasis added). The trial judge then went on to discuss the other two factors. And while
    he found that Carr had “demonstrated adaptive skill deficits in at least two (2) of the
    adaptive skill areas noted in the applicable definitions,” he did not specify in which two
    areas he found those adaptive deficits, nor did he discuss the severity or extent of those
    deficits.9
    E.     The circuit judge used an erroneous legal standard.
    9
    While the judge did not make a specific finding regarding the onset-before-eighteen
    prong in his initial order, he noted in his order denying Carr’s motion for reconsideration
    that Carr said he had “overlooked” evidence indicating that Carr had manifested signs of
    intellectual disability before age eighteen. The judge said he “did not ignore [that]
    evidence.” Rather, he “simply had a different take on such evidence as does defense
    counsel.” In short, the trial judge found that Carr had failed to prove the onset-before-
    eighteen prong as well.
    23
    ¶58.      The ultimate decision of whether an individual is intellectually disabled for purposes
    of the Eighth Amendment rests with the trial judge. Doss v. State, 
    19 So. 3d 690
    , 714 (Miss.
    2009). The trial judge “sits as the trier of fact and assesses the totality of the evidence as well
    as the credibility of witnesses.” 
    Id. The burden
    of proof “is on the petitioner to show ‘by a
    preponderance of the evidence’ that he [or she] is entitled to relief.” 
    Goodin, 102 So. 3d at 1111
    (quoting 
    Doss, 19 So. 3d at 694
    ); see also Miss. Code § 99-39-23(7) (Rev. 2015) (“No
    relief shall be granted under this article unless the petitioner proves by a preponderance of
    the evidence that he is entitled to the relief.”). And all three of the factors—significantly
    subaverage intellectual functioning, significant deficits in adaptive behavior, and
    manifestation before age eighteen—must be met before the petitioner can be classified as
    intellectually disabled and declared ineligible for execution under Atkins. 
    Doss, 19 So. 3d at 709
    .
    ¶59.      If the trial court denies relief, this Court will not disturb that court’s factual findings
    unless they are clearly erroneous. Goodin v. State, 
    102 So. 3d 1102
    , 1111 (Miss. 2012)
    (quoting 
    Doss, 19 So. 3d at 694
    ). Factual findings are not clearly erroneous simply because
    this Court would have decided the case differently. Booker v. State, 
    5 So. 3d 356
    , 358 n.2
    (Miss. 2008) (quoting Easley v. Cromartie, 
    532 U.S. 234
    , 242, 
    121 S. Ct. 1452
    , 
    149 L. Ed. 2d
    430 (2001)). But this limitation upon our scope of review is enforced “only where the
    factfinder applied the correct legal standard.” McClendon v. State, 
    539 So. 2d 1375
    , 1377
    (Miss. 1989) (emphasis added). On the other hand, where . . . the trial judge has applied an
    erroneous legal standard, we should not hesitate to reverse.” 
    Id. (emphasis added).
    And
    24
    questions of law are reviewed de novo. Goodin v. State, 
    102 So. 3d 1102
    , 1111 (Miss. 2012)
    (citation omitted).
    ¶60.   As discussed above, the current medical literature establishes three criteria for courts
    to consider: (1) significantly subaverage intellectual functioning, (2) significant deficits in
    adaptive functioning, and (3) manifestation before age eighteen. Chase v. State, 
    873 So. 2d 1013
    , 1029 (Miss. 2004). With regard to the first criterion, this Court recognized that
    medical literature generally quantifies significantly subaverage intellectual functioning as
    two standard deviation below the mean full-scale IQ score, 70, but that “[a]ccording to the
    DSM-IV, ‘it is possible to diagnose Mental Retardation in individuals with IQ’s between 70
    and 75 who exhibit significant deficits in adaptive behavior.’” 
    Id. at 1028.
    ¶61.   But in Hall v. Florida, the United States Supreme Court made clear that states’
    discretion to establish criteria is not unlimited. 
    Hall, 134 S. Ct. at 1998
    (“But Atkins did
    not give the States unfettered discretion to define the full scope of the constitutional
    protection.”). That Court held that “[t]he legal determination of intellectual disability is
    distinct from a medical diagnosis, but it is informed by the medical community’s diagnostic
    framework.” 
    Id. at 2000.
    Relying on “the medical community’s diagnostic framework,”
    the Supreme Court further stated “[i]t is not sound to view a single factor as dispositive of
    a conjunctive and interrelated assessment.” 
    Id. at 2001.
    ¶62.   So according to the Supreme Court, the Florida statute at issue—which categorically
    excluded from its definition of intellectual disability all persons with an IQ above 70—failed
    constitutional scrutiny not only because it “fail[ed] to take into account the standard error of
    measurement, . . . but also [because it] bars an essential part of a sentencing court’s inquiry
    25
    into adaptive functioning.” 
    Id. “[W]hen a
    defendant’s IQ test score falls within the test’s
    acknowledged and inherent margin of error, the defendant must be able to present additional
    evidence of intellectual disability, including testimony regarding adaptive functioning.” 
    Id. Thus, a
    legal standard that views a full-scale IQ score as dispositive of intellectual disability
    without performing and balancing an interrelated analysis of adaptive functioning, runs afoul
    of the Eighth Amendment.
    ¶63.    The prevailing medical literature—which this Court has adopted as Mississippi’s legal
    standard—confirms this view. The Diagnostic and Statistical Manual, Fifth Edition, states
    that:
    IQ test scores are approximations of conceptual functioning but may be
    insufficient to assess reasoning in real-life situations and mastery of practical
    tasks. For example, a person with an IQ score above 70 may have such severe
    adaptive behavior problems in social judgment, social understanding, and other
    areas of adaptive functioning that the person’s actual functioning is
    comparable to that of individuals with a lower IQ score. Thus, clinical
    judgment is needed in interpreting the results of IQ tests.
    DMS-V at 37 (emphasis added). So subaverage intellectual functioning (the first criterion)
    must be considered conjunctively with—and balanced with—adaptive functioning (the
    second criterion). Specifically, when the petitioner’s full-scale IQ falls within the possible
    range for intellectual disability, the factfinder must consider whether the petitioner exhibits
    such severe deficits in adaptive functioning to support adjudication as intellectually disabled.
    ¶64.    Here, the circuit judge held:      “It can be said comfortably that Carr’s IQ, as
    demonstrated by the tests which were given, falls somewhere in the 70-75 range.”
    But—despite Carr’s full-scale IQ between 70 and 75—the circuit judge failed to consider
    intellectual and adaptive functioning as an interrelated analysis. Instead, he found that Carr
    26
    failed to prove subaverage intellectual functioning, and that this failure alone disposed of
    the case. He stated: “[T]his court cannot find by a preponderance of the evidence that Carr
    has carried his burden of proof” to show significantly sub-average intellectual functioning.
    “[T]his finding alone is sufficient to deny Carr’s claim of mental retardation.” This finding
    was clearly erroneous as a matter of law.
    ¶65.   Then, based on the “significance of [his] decision,” the circuit judge stated he would
    proceed to consider the two remaining criteria. But despite finding that Carr had proven the
    existence of two adaptive functioning deficits, the circuit judge did not identify those deficits,
    make any findings regarding their severity, or consider them as part of an interrelated
    analysis with Carr’s intellectual functioning. Because “the medical community’s diagnostic
    framework” recognizes that Carr’s IQ between 70 and 75, coupled with “severe adaptive
    behavior problems” could support a diagnosis of intellectual disability, the circuit judge
    applied an incorrect legal standard by treating Carr’s IQ score alone as dispositive of this
    case, and by failing to balance and analyze his adaptive functioning deficits with his IQ
    score. We therefore reverse the trial court judgment and remand this case to provide the
    circuit judge an opportunity to consider whether Carr’s adaptive functioning deficits—which
    the circuit judge found to exist—are so severe that Carr should be ruled intellectually
    disabled through an interrelated analysis with his IQ scores, which the circuit judge found
    to be between 70 and 75.10
    10
    Carr also must establish manifestation before age eighteen. Because the circuit
    judge found that adaptive functioning deficits existed based on evidence which largely
    focused on Carr’s academic performance before age eighteen, we instruct the trial court to
    review its findings on this prong upon remand.
    27
    CONCLUSION
    ¶66.   For the foregoing reasons, we reverse the circuit judge’s ruling and remand this case
    for new factual findings applying the correct legal standard. We therefore reverse the
    judgment of the Quitman County Circuit Court and remand this case for proceedings
    consistent with this opinion.

    MAXWELL, JUSTICE, SPECIALLY CONCURRING:
    ¶68.   This case presents a battle of experts and under a typical common-sense approach to
    expert testimony should be affirmed. The judge weighed both side’s experts, and after doing
    so, concluded Carr failed in his burden of proof. While this is generally how our courts
    handle expert testimony, the majority finds the trial judge erred in this process, essentially
    for thinking like a jurist, not a doctor.
    ¶69.   The majority reverses the judge’s decision because he utilized a general legal
    framework and did not follow “the medical community’s diagnostic framework.” Though
    this reasoning is counterintuitive to how our trial courts operate, it is the exact method
    dictated by the United States Supreme Court’s holding in Hall.11 So I am constrained to find

    the majority correctly applies Hall when it finds the trial judge reversibly erred by “failing
    to balance and analyze his adaptive functioning deficits with his IQ score.”
    ¶70.    But I write separately because this case is a prime example of the confusion created
    by Atkins12 and compounded by Hall. Undoubtedly, whether someone is ineligible for the
    death penalty due to intellectual disability is a legal question. Yet it is a legal question the
    United States Supreme Court has said must be largely informed by the medical community.13
    And therein lies the problem.
    ¶71.   Medicine—and specifically the field of psychology—is a completely different
    discipline than the law. Indeed, psychology openly embraces ever-evolving definitions14—a
    stark contrast to our common law’s doctrine of stare decisis. The trial judge in this case
    certainly felt this tension. In his final order, he lamented “the difficulty when attempting to
    make a concrete decision when the factors upon which the decision must be based are
    grounded in the soft sciences.”
    ¶72.   This begs the question—Why are we asking our trial judges to wade into the soft
    sciences and make medical diagnoses? We do not do that in other legal contexts. According
    to the majority, the trial judge here failed to “recognize[] that Carr’s IQ between 70 and 75,

    coupled with ‘severe adaptive behavior problems’ could support a diagnosis of intellectual
    disability.” But our trial judges are not licensed forensic psychologists. Instead, their role
    as a neutral and detached magistrate necessarily depends on licensed forensic psychologists
    to give their expert diagnoses. This is the very reason why this Court requires every Atkins
    claimant to produce at least one licensed forensic psychologist willing to testify to a
    reasonable degree of certainty that the claimant meets the adopted clinical definitions of
    intellectually disabled.15
    ¶73.   Here, the judge was presented with two expert opinions. Carr’s expert, Dr. Gerald
    O’Brien, testified Carr was intellectually disabled. But O’Brien refused to specify how he
    reached his conclusions. Further, he admitted he was not personally involved in the
    investigative process. The State’s expert, Dr. Gilbert Macvaugh, by contrast, testified he
    could not reach a reasonable degree of certainty whether Carr was or was not intellectually
    disabled, based on the lack of data. Moreover, the one lay witness was “unhelpful”—neither
    leading credence or doubt to either expert’s view. The trial judge ultimately found the
    State’s expert was more credible, agreeing the question of Carr’s intellectual disability was
    “too close to call.” The judge then considered this evidentiary finding in light of the
    applicable legal standard. And he held Carr to his legally required burden of proof. This
    type of analysis should be legally sufficient, since it is the exactly how judges size up expert
    testimony in other contexts. But it is not under Atkins and Hall.
    ¶74.   Logic dictates we should allow our judges to function like trial judges and to weigh
    the evidence—particularly, the credibility of the expert witnesses and their diagnoses—to
    15

    873 So. 2d 1013
    , 1029 (Miss. 2003).

    make a finding whether the claimant met his or her burden of proof to show intellectual
    disability. It makes no sense to demand our trial judges pretend they are psychologists and
    to delve into the three criteria that comprise the clinical definition of intellectual disability
    to make an independent diagnosis. But unless and until the United States Supreme Court
    untethers its Eighth Amendment jurisprudence from the ever-changing clinical definition of
    intellectual disability, this is the exact approach our trial judges must utilize. Until then, our
    judges apparently will have to don the hats of psychologists and apply the proper “diagnostic
    framework.”16
    COLEMAN, J., JOINS THIS OPINION. RANDOLPH, P.J., JOINS THIS
    OPINION IN PART.
    KING, JUSTICE, CONCURRING IN PART AND IN RESULT:
    ¶75.   Because I disagree with the manner in which the majority reframed the issues on
    appeal and with the majority’s failure to address the issue of Carr’s elementary school
    teacher’s opinion, I write separately. I agree, however, with the majority’s assessment that
    the trial court erred in finding IQ alone determinative and with the decision to reverse and
    remand the case.
    1. The Standard of Review Argument
    ¶76.   The majority “restated” the issue on appeal as “Is it unconstitutional for Carr to bear
    the burden of proof here, when the trial judge found that the question of his intellectual
    disability was ‘too close to call’?” Yet, the exact issue raised by Carr was “Will the circuit
    court’s holding that the outcome of the Atkins hearing was a tie and that, because of the
    16
    
    Hall, 134 S. Ct. at 2000
    .
    31
    burden of proof, the State must prevail, result in an unacceptable risk of executing a person
    with mental retardation in violation of Atkins v. Virginia and Chase v. State?” While the
    distinction is subtle, Carr argued that the facts of his particular case create an unacceptable
    risk of executing a person with an intellectual disability.17 The majority’s phrasing broadens
    that to a more general question of whether it is unconstitutional for Carr to bear the burden
    of proof in a close case. The majority has unnecessarily “restated” the issue appealed, and
    with this I take umbrage. Moreover, it is unnecessary for the majority to address this issue,
    given that it found the trial court erred in finding IQ determinative, and it reverses and
    remands because this issue is dispositive.
    2. Reliance on Teacher’s Opinion
    ¶77.   The trial court erred in relying on a teacher’s opinion documented within the State’s
    report to directly counter expert testimony. In other words, the teacher did not testify at the
    hearing and certainly was not qualified as an expert. The State argues that the teacher’s
    statements were admissible, but that argument misses the point. Carr does not argue that the
    teacher’s statements were inadmissible; rather, he argues that the manner in which the circuit
    court relied upon those statements was error, as the trial court appeared to improperly give
    the teacher’s opinion the weight of an expert opinion.
    ¶78.   The trial court stated in its order:
    Contrary to O’Brien’s opinion, Carr’s sixth grade teacher opined that
    Carr did not suffer from mental retardation during his earlier years but rather
    17
    I note that this hearing was held when the medical term for what is now termed
    “intellectual disability” was “mental retardation.” Thus, to the extent I refer to the hearing
    or how witnesses at the hearing opined, I may use the terminology used at that time.
    Otherwise, I will use the term “intellectual disability.”
    32
    suffered from a learning disability. . . . She indicated that special education
    was available during that time period but that Carr was not placed into special
    education. It was apparent that O’Brien did not put great stock in the opinions
    of this former teacher. On the other hand, Macvaugh appears to have put more
    reliance upon the teacher’s opinion. Macvaugh suggested that because mental
    retardation is primarily an impediment to learning, it more often than not is
    first demonstrated in the area of academics. As such, teachers are often the
    first to note the signs of mental retardation. As to the ultimate issue of whether
    Carr demonstrated signs of mental retardation prior to the age of 18,
    Macvaugh again found the issue “too close to call.”
    (Emphasis added.) The trial court ultimately concluded that “Some thirty years after grade
    school, the defense expert reviews Carr’s academic record and finds mental retardation,
    while the individual who actually taught Carr, someone who saw him day after day when
    Carr was in school and who has no interest in this matter at all, is of the view that Carr was
    not mentally retarded, but rather suffered from a learning disability.”
    ¶79.   In both provisions of the order mentioning Carr’s teacher, the trial court uses her
    opinion to directly counter the expert opinion of Dr. O’Brien. Perhaps this was done because
    Dr. Macvaugh’s expert opinion was not in direct opposition to Dr. O’Brien’s. Dr. O’Brien
    found that Carr was mentally retarded, while Dr. Macvaugh found the issue of Carr’s mental
    retardation too close to call. The teacher was the only person of the definitive opinion that
    Carr was not mentally retarded. Yet, the telephone interview of a teacher by the State on
    September 15, 2009, for a hearing that occurred on February 6, 2013, in no way constitutes
    an expert opinion.
    ¶80.   Mississippi Rule of Evidence 701 provides that lay opinion testimony is limited to an
    opinion that is: “(a) rationally based on the witness’s perception; (b) helpful to clearly
    understanding the witness’s testimony or to determining a fact in issue; and (c) not based on
    33
    scientific, technical, or other specialized knowledge within the scope of Rule 702.” Miss.
    R. Evid. 701. Rule 702 provides that
    A witness who is qualified as an expert by knowledge, skill, experience,
    training, or education may testify in the form of an opinion or otherwise if:
    (a) the expert’s scientific, technical, or other specialized knowledge will help
    the trier of fact to understand the evidence or to determine a fact in issue;
    (b) the testimony is based on sufficient facts or data;
    (c) the testimony is the product of reliable principles and methods; and
    (d) the expert has reliably applied the principles and methods to the facts of the
    case.
    Miss. R. Evid. 702. The determination of whether Carr is intellectually disabled is clearly
    one that requires specialized knowledge. Carr’s teacher was never qualified as an expert
    with such knowledge. While certainly the State’s report containing her interview was
    admissible evidence, relying on her lay opinion that Carr was not mentally retarded,
    especially to directly contradict the opinion of the defense expert, was improper. Because
    the trial court improperly treated the teacher’s opinion as expert opinion, I believe this also
    warrants reversing and remanding this case for a new Atkins hearing in which the trial court
    should be more cognizant as to its reliance on such evidence.
    ¶81.   For these reasons, I concur with the majority’s conclusion that the trial court erred in
    finding IQ dispositive, and with its assessment that IQ must be examined in conjunction with
    adaptive functioning to determine whether intellectual disability exists, and I consequently
    agree with the decision to reverse the judgment and remand this case. However, I disagree
    with the majority’s decision to address the burden of proof argument, an argument that it
    34
    problematically “restated.” I also believe that we should address the issue of the trial court’s
    improper use of the teacher’s opinion, and admonish the court not to rely on the opinion of
    the teacher as if it was an expert opinion.
