    2014 IL 116306
    IN THE
    SUPREME COURT
    OF
    THE STATE OF ILLINOIS
    (Docket No. 116306)
    In re DETENTION OF JOHN NEW, JR. (The People of the State of Illinois,
    Appellant, v. John New, Jr., Appellee).
    Opinion filed November 20, 2014.
    JUSTICE THEIS delivered the judgment of the court, with opinion.
    Chief Justice Garman and Justices Freeman, Thomas, Kilbride, Karmeier, and
    Burke concurred in the judgment and opinion.
    OPINION
    ¶1       At issue in this case is whether the circuit court of Cook County erred in admitting
    certain expert testimony regarding a diagnosis of hebephilia at respondent’s civil
    commitment trial without first conducting an evidentiary hearing pursuant to Frye v.
    United States, 
    293 F. 1013
    (D.C. Cir. 1923) (“Frye hearing”) to determine whether the
    diagnosis had been generally accepted as a valid mental disorder in the relevant
    scientific community. For the reasons that follow, we hold that the diagnosis of
    hebephilia is subject to the Frye standards for the admissibility of novel scientific
    evidence, and that a hearing is necessary in this case to determine its general
    acceptance.
    ¶2                                       BACKGROUND
    ¶3       In March 2005, the State filed a petition to commit respondent, John New, Jr., to the
    Department of Human Services (DHS) as a sexually violent person under the Sexually
    Violent Persons Commitment Act (Act) (725 ILCS 207/1 et seq. (West 2004)). The
    petition alleged that respondent had a history of committing sexually violent offenses,
    citing respondent’s 1987 conviction of two counts of aggravated criminal sexual
    assault against a 12-year-old boy, and his 1995 conviction of aggravated criminal
    sexual assault and two counts of criminal sexual assault against a 14-year-old boy.
    Respondent was sentenced to seven years in prison for the 1987 conviction, and was
    sentenced to two consecutive terms of seven and six years respectively for the 1995
    conviction. The petition further alleged that respondent had been diagnosed with
    “paraphilia not otherwise specified, [paraphilia NOS], sexually attracted to adolescent
    males,” that his condition affected his emotional or volitional capacity which
    predisposed him to commit acts of sexual violence, and that there was a substantial
    probability that he would engage in future acts of sexual violence.
    ¶4       Prior to trial, respondent filed a motion in limine to bar the expert testimony from
    the State’s evaluators regarding their diagnosis. Respondent contended that the
    experts’ opinions failed to meet the Frye standards for the admissibility of novel
    scientific evidence. Specifically, respondent argued that in recent years the diagnosis,
    “parapaphilia NOS, sexually attracted to adolescent males,” which is otherwise
    referred in the academic literature as hebephilia, has been applied in civil commitment
    proceedings as the basis for an accepted mental condition. Respondent maintained that
    the purported mental condition was not listed as an accepted mental disorder in an
    authoritative reference manual, was not grounded in sound scientific principles, and
    was not generally accepted as a valid diagnosis within the psychiatric and
    psychological communities. In support of his motion, he attached several exhibits,
    including numerous articles criticizing a proposal to include the diagnosis as a
    qualifying mental disorder in the next edition of the American Psychiatric
    Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM).
    ¶5       In response, the State argued that the diagnosis was made in reliance upon the DSM
    category for paraphilia NOS, that there was nothing novel about the use of the DSM as
    a methodology, that paraphilia NOS is a frequently diagnosed mental disorder in
    sexually violent persons commitment proceedings, and that it has gained general
    acceptance by professionals who assess sexually violent offenders. The trial court
    denied respondent’s motion, concluding that the expert testimony was admissible
    without the need for a Frye hearing. The court did not preclude respondent from
    -2-
    cross-examining the State’s experts based upon any scientific disagreement regarding
    the validity of the diagnosis.
    ¶6       At trial, Dr. Fogel testified that he is a licensed forensic psychologist. In that
    capacity, he conducted a clinical evaluation of respondent to determine if he was a
    candidate for commitment under the Act. As part of that evaluation, Dr. Fogel
    reviewed respondent’s master file, which contained information regarding
    respondent’s incarceration, his medical file, and police reports regarding his various
    criminal offenses. Additionally, Dr. Fogel interviewed respondent in 2004 and 2010.
    ¶7       Dr. Fogel considered respondent’s sexual offense history. In 1980, at the age of 17,
    respondent was convicted of contributing to the delinquency of a minor and received
    supervision. In 1987, he was convicted of aggravated criminal sexual assault of a
    12-year-old boy. While on mandatory supervised release for that conviction, he was
    convicted for soliciting a young male prostitute in his early 20s. Thereafter, in 1995, he
    was convicted of one count of aggravated criminal sexual assault and two counts of
    criminal sexual assault of a 14-year-old boy. Respondent was 32 years old at the time.
    One month prior to his release from the Department of Corrections, respondent
    received a sexual misconduct ticket for soliciting a 19-year-old male for sex. This
    individual had recently been transferred from the juvenile detention facility and was
    reportedly young looking. While awaiting trial in DHS custody, respondent requested
    to share a room with a recently-arrived detainee whom he had known in prison. Dr.
    Fogel noted documentation indicating that respondent had been the detainee’s
    basketball coach when the detainee was 11 years’ old. Dr. Fogel was of the opinion that
    respondent continued to fixate on this individual.
    ¶8       Dr. Fogel testified regarding respondent’s admitted attraction to younger looking
    men and respondent’s feelings of powerlessness over his urges and sexual fantasies
    about younger men. Dr. Fogel noted that respondent had a history of befriending
    younger males, often overestimating their actual ages, purchasing items for them, and
    having sexual fantasies about them. Respondent described himself to Dr. Fogel at times
    as a passive recipient of the advances, and at other times admitted that he sought out
    certain individuals with a history of sexual abuse or individuals that were
    underprivileged or vulnerable in some way. According to Dr. Fogel, respondent
    reported a preference for tall, athletic, African American, young-looking men without
    facial or chest hair.
    ¶9      Following the evaluation, Dr. Fogel diagnosed respondent with paraphilia NOS,
    sexually attracted to adolescent males or alternatively sexually attracted to early
    -3-
    pubescent males, ranging from age 11 to 14 years old. In formulating a diagnosis, Dr.
    Fogel relied upon the Diagnostic and Statistical Manual of Mental Disorders, 4th
    edition, Text Revision (DSM-IV-TR), which was the current version of the DSM at the
    time. American Psychiatric Association, Diagnostic and Statistical Manual of Mental
    Disorders, Fourth Edition, Text Revision, DSM-IV-TR (2000). The manual, which is
    published by the American Psychiatric Association, provides an authoritative
    categorical classification of mental disorders.
    ¶ 10       Dr. Fogel explained that a paraphilia, as identified in the DSM, refers to a general
    class of sexual disorders. There are two general criteria for establishing a paraphilic
    disorder related to children or other nonconsenting persons. The first criteria requires
    that over a period of at least six months the individual experiences recurrent, intense,
    sexually arousing fantasies, urges or behaviors generally involving children or other
    nonconsenting persons. The second criteria requires either that the sexual urges or
    fantasies cause the individual clinically significant distress or impairment, or the
    individual has acted on the sexual urges.
    ¶ 11       Dr. Fogel testified that a paraphilia NOS diagnosis indicates that the individual
    meets the general overall diagnostic criteria for a paraphilia, but the condition fails to
    fall into one of the specifically listed paraphilic disorders in the DSM, such as
    voyeurism, sadism, or pedophilia. Dr. Fogel then identified the specific target of the
    paraphilia in respondent’s case as a sexual attraction to early pubescent males. Dr.
    Fogel expressed that respondent meets the criteria for that diagnosis based on his
    sexual conduct with the 12- and 14-year-old boys, and his admitted fantasies focusing
    on early pubescent individuals during his incarceration, as well as fantasies about those
    adolescents he observed on television.
    ¶ 12        On cross-examination, Dr. Fogel agreed that there is a debate about how the
    paraphilia NOS diagnosis should be applied within his field. He acknowledged the
    controversy over whether there should be a category in the DSM for those individuals
    with a sexual arousal to early pubescent males within the age range of 11 to 14, which
    has been described as hebephilia. He explained that unlike hebephilia, pedophilia is a
    listed diagnosis in the DSM. Pedophilia requires an interest in prepubescent children,
    and provides a general age category as including children 13 years old and younger. Dr.
    Fogel stated that the problem with that limitation is that a 13 year old is generally not
    prepubescent. Therefore, there was a debate about how the DSM should be modified.
    ¶ 13      At the time of trial, Dr. Fogel was aware of a proposal to modify the language of the
    pedophilia diagnosis to include hebephilia, the attraction to adolescent individuals in
    -4-
    the 11 to 14 year old age range. Dr. Fogel acknowledged that his diagnosis of paraphilia
    NOS, sexually attracted to early pubescent males, or hebephilia, was essentially the
    same as the diagnosis proposed for inclusion in the upcoming fifth edition of the DSM
    (DSM-5). He agreed that there was no specific listing of hebephilia as a paraphilic
    disorder in the DSM.
    ¶ 14       With respect to respondent’s probability of reoffending, Dr. Fogel administered
    various tests and considered certain additional factors which can increase and mitigate
    the risk of reoffending. Based upon these measurements, Dr. Fogel determined that
    respondent presented a high risk of recidivism. Accordingly, it was his opinion that it
    was substantially probable that respondent would commit acts of sexual violence in the
    future.
    ¶ 15       Dr. Robert Brucker testified that he is a licensed clinical psychologist qualified as
    an expert in the area of sex offender evaluation and risk assessment and treatment. In
    December 2005, he was assigned to conduct a clinical evaluation of respondent to
    determine whether he was a candidate for commitment. Dr. Brucker reviewed
    respondent’s master file, performed psychological testing, and conducted an interview
    with him in January 2006.
    ¶ 16       As part of his evaluation, Dr. Brucker also relied upon the DSM-IV-TR as an
    authoritative reference manual in his field. Relevant here, Dr. Brucker diagnosed
    respondent with paraphilia NOS, sexually attracted to adolescent males, non-exclusive
    type. He explained that a paraphilia is essentially a deviant sexual interest. To establish
    a paraphilic disorder, an individual needs to have recurrent, intense urges, arousals,
    fantasies or behaviors toward a sexually deviant interest. These urges need to be
    present for at least six months, and the individual needs to have acted on the urges or
    fantasies, or they have to have caused significant clinical stress or impairment.
    ¶ 17       Dr. Brucker noted that respondent exhibited a clear sexual interest toward
    adolescent males between the ages of 12 and 15. It was Dr. Brucker’s opinion that the
    disorder impacted respondent’s emotional or volitional capacity because despite
    having received legal consequences for his behaviors respondent continued to engage
    in paraphilic, sexually deviant, behavior. This suggested to Dr. Brucker that respondent
    was unable to control this behavior. In addition, Dr. Brucker utilized various
    assessment tools along with other risk factors to predict that respondent was at a high
    risk for reoffending.
    ¶ 18       Dr. Brucker acknowledged on cross-examination that the paraphilia NOS category
    of diagnosis is a miscellaneous one and that there is nothing specifically in the DSM
    -5-
    about an attraction to adolescent males being a paraphilia. He testified that paraphilia
    NOS exists because it would not be practical for the DSM to identify and itemize each
    separate deviant sexual interest. The ones that tend to be the most common are the ones
    listed, such as pedophilia or exhibitionism or voyeurism. He acknowledged that the
    DSM provides a list of examples under the paraphilia NOS category, and that those
    examples may not be common paraphilias, but he stated that the list of examples is not
    intended to be comprehensive. Dr. Brucker additionally agreed that the term “garbage
    can diagnosis” has been commonly used to refer to the paraphilia NOS category of
    diagnoses, but he did not believe that it was a useless diagnosis.
    ¶ 19       Dr. Kirk Witherspoon testified as an expert in the field of clinical psychology on
    behalf of respondent. He performed his evaluation of respondent in January 2010. As
    part of his evaluation, he reviewed materials regarding respondent’s sexual offense
    history, family history, incarceration history, and the evaluations of Fogel and Brucker.
    Additionally, Dr. Witherspoon interviewed respondent and administered various
    psychological tests.
    ¶ 20       Dr. Witherspoon was of the opinion that respondent’s prior sexual offense history
    was not indicative of a mental disorder because an attraction to adolescents is not a
    psychopathology. Dr. Witherspoon stated that it is statistically normal for adults to be
    sexually attracted to sexually immature adolescents. Although it is illegal to act on
    those feelings with someone under the age of consent, which varies by state, the fact
    that something is illegal does not make it pathological. According to Dr. Witherspoon,
    “paraphilia NOS, sexually attracted to adolescent males,” is not a generally accepted
    diagnosis.
    ¶ 21       In assessing respondent’s risk of reoffending, Dr. Witherspoon utilized various
    assessment tools. Based on the outcome of these tests, respondent had a moderately
    high risk of reoffending which would decrease over 10 years to almost no risk.
    ¶ 22        At the conclusion of the evidence, the jury found respondent to be a sexually
    violent person under the Act, and the trial court committed him to the Department of
    Human Services for care and treatment in a secured facility. Respondent appealed.
    While the case was pending on appeal, in 2013, the DSM-5 was published. The DSM-5
    does not list hebephilia as a paraphilic disorder or as an expansion of the specifically
    listed pedophilic disorder. American Psychiatric Association, Diagnostic and
    Statistical Manual of Mental Disorders, 5th Edition, DSM-5 Paraphilic Disorders
    685-705 (2013).
    -6-
    ¶ 23       On appeal, respondent argued, in part, that the trial court erred in admitting the
    testimony of Dr. Fogel and Dr. Brucker without first conducting a Frye hearing. The
    appellate court agreed, holding that a diagnosis of a novel condition is subject to the
    general acceptance test under Frye (
    2013 IL App (1st) 111556
    , ¶ 59), and that as the
    proponent of the evidence, the State failed to meet its burden of showing its general
    acceptance. 
    Id. ¶ 61.
    Accordingly, the court reversed and remanded the case for a Frye
    hearing, and, if necessary, a new trial. 
    Id. ¶ 62.
    We subsequently allowed the State’s
    petition for leave to appeal. Ill. S. Ct. R. 315(a) (eff. July 1, 2013).
    ¶ 24                                           ANALYSIS
    ¶ 25       In Illinois, the admission of scientific evidence is governed by the Frye standard (In
    re Commitment of Simons, 
    213 Ill. 2d 523
    , 529 (2004) (citing Frye v. United States, 
    293 F. 1013
    (D.C. Cir. 1923)), which has now been codified by the Illinois Rules of
    Evidence: “Where an expert witness testifies to an opinion based on a new or novel
    scientific methodology or principle, the proponent of the opinion has the burden of
    showing the methodology or scientific principle on which the opinion is based is
    sufficiently established to have gained general acceptance in the particular field in
    which it belongs.” Ill. R. Evid. 702 (eff. Jan. 1, 2011).
    ¶ 26        The purpose of the Frye test is to exclude new or novel scientific evidence that
    undeservedly creates “a perception of certainty when the basis for the evidence or
    opinion is actually invalid.” Donaldson v. Central Illinois Public Service Co., 
    199 Ill. 2d
    63, 78 (2002), abrogated on other grounds by 
    Simons, 213 Ill. 2d at 530
    . Imposition
    of the test serves to prevent the jury from simply adopting the judgment of an expert
    because of the natural inclination of the jury to equate science with truth and, therefore,
    accord undue significance to any evidence labeled scientific. People v. McKown, 
    226 Ill. 2d 245
    , 254 (2007). We review de novo a trial court’s determination of whether a
    Frye hearing is necessary and whether there is general acceptance in the relevant
    scientific community. 
    Simons, 213 Ill. 2d at 531
    .
    ¶ 27                                   Testimony Subject To Frye
    ¶ 28       Initially, we must consider whether expert testimony involving a purported mental
    diagnosis is the type of scientific evidence subject to the screening function served by
    the Frye test. In Donaldson, this court explained that the Frye test does not concern an
    -7-
    expert’s ultimate conclusion but, instead, focuses on the underlying scientific principle,
    test, or technique used to generate that conclusion. Donaldson, 
    199 Ill. 2d
    at 77; see
    also In re Marriage of Alexander, 
    368 Ill. App. 3d 192
    , 197 (2006) (when an expert
    opinion is derived solely based upon observation and experience, that opinion is
    generally not considered scientific evidence subject to the Frye test). Relying on this
    court’s opinion in Donaldson, the State maintains that a diagnosis is never subject to
    Frye because it is not a scientific technique or test used to diagnose but, rather, an
    expert’s conclusion based on training and experience.
    ¶ 29       Although this court has not had occasion to consider specifically whether expert
    testimony involving a purported mental diagnosis is the type of scientific evidence that
    could be subject to the Frye test, our appellate court has previously applied the Frye
    standard to expert testimony related to a syndrome or diagnosis. In People v.
    Shanahan, 
    323 Ill. App. 3d 835
    , 839 (2001), the court held that the expert’s testimony
    related to battered child syndrome was subject to the Frye standard. In Bernardoni v.
    Industrial Comm’n, 
    362 Ill. App. 3d 582
    , 594 (2005), the court subjected proffered
    expert testimony on multiple chemical sensitivity to the Frye standard to determine
    whether it was a clinically valid diagnosis. In comparison, in Noakes v. National R.R.
    Passenger Corp., 
    363 Ill. App. 3d 851
    , 856 (2006), the court held there was no need for
    a Frye hearing where there was no dispute that carpal tunnel syndrome existed as a
    valid diagnosis.
    ¶ 30       Additionally, in the context of civil commitment proceedings, in McGee v. Bartow,
    
    593 F.3d 556
    (7th Cir. 2010), the Seventh Circuit acknowledged that “a particular
    diagnosis may be so devoid of content, or so near-universal in its rejection by mental
    health professionals, that a court’s reliance on it to satisfy the ‘mental disorder’ prong
    of the statutory requirements for commitment would violate due process.” 
    McGee, 593 F.3d at 577
    .
    ¶ 31       Furthermore, the United States Supreme Court in Kansas v. Hendricks, 
    521 U.S. 346
    (1997), recognized the importance of distinguishing between the dangerous sexual
    offender subject to civil commitment, and other dangerous, but typical, recidivists, who
    are more properly dealt with through the criminal system. 
    Hendricks, 521 U.S. at 360
    .
    The Court found that this distinction was made possible, in part, by the “presence of
    what the ‘psychiatric profession itself classifie[d] ... as a serious mental disorder.’ ”
    Kansas v. Crane, 
    534 U.S. 407
    , 412 (2002) (quoting 
    Hendricks, 521 U.S. at 360
    ).
    ¶ 32      Thus, in the context of civil commitment, courts have acknowledged the
    importance of establishing an underlying mental condition recognized by the mental
    -8-
    health community, and have acknowledged that a diagnosis may be so unsupported by
    science that it should be excluded from consideration by the trier of fact. These same
    concerns are relevant to our Frye standard.
    ¶ 33       Here, the question raised by respondent is whether paraphilia NOS, sexual
    attraction to early adolescent males, otherwise known as hebephilia, is a diagnosable
    mental condition based upon legitimate scientific principles and methods. Contrary to
    the State’s assertion, respondent does not seek to test the conclusions drawn by the
    experts who testified here based on their clinical observation and experience that
    respondent exhibits the characteristics of particular condition. Rather, the science
    behind the condition is at issue, as evidence by the supporting documentation presented
    by respondent regarding flawed methodology. See, e.g., Joseph J. Plaud, Are there
    “Hebephiles” Among Us? A Response to Blanchard et al. (2008), 38 Archives of
    Sexual Behav. 326 (2009) (setting forth “multiple methodological issues that preclude
    a call for the establishment of hebephilia as a diagnostic entity in the DSM-V”);
    Thomas K. Zander, Adult Sexual Attraction to Early-Stage Adolescents: Phallometry
    Doesn’t Equal Pathology, 38 Archives of Sexual Behav. 329 (2009) (“Any new or
    expanded DSM diagnosis that can have implications as profound as the one proposed
    by Blanchard et al. requires a broad base of replicated research (not just one study with
    a glaring methodological omission), as well as extensive field testing to ensure its
    interrater reliability, and a full and open debate about its conceptual validity.”). This is
    the type of scientific evidence that the analytic framework established by Frye was
    designed to address.
    ¶ 34       We next consider whether the diagnosis is predicated on new or novel science.
    Although not always easy to identify, we have held that generally, scientific evidence is
    new or novel if it is “ ‘original or striking’ ” or does “ ‘not resembl[e] something
    formerly known’ ” or used. Donaldson, 
    199 Ill. 2d
    at 79 (quoting Webster’s Third New
    International Dictionary 1546 (1993)). The State represents that the term hebephilia has
    been previously applied in many contexts in the scientific literature as a descriptive
    label to classify a sexual attraction to adolescents. However, its use as the basis for a
    mental condition is of more recent origin as the debate surrounding its proposed
    inclusion and subsequent rejection in the DSM-5 demonstrates.
    ¶ 35       As Dr. Fogel testified, the same diagnosis was the subject of a recent proposal to be
    included in the DSM-5 based on the research of Ray Blanchard and his colleagues. Ray
    Blanchard et al., Pedophilia, Hebephilia, and the DSM-V, 38 Archives of Sexual
    Behav. 335 (2009). The proposal sought to include hebephilia as a listed category of
    paraphilic disorder, or as an extension of the already specified disorder, pedophilia. 
    Id. -9- The
    authors noted that studies have “demonstrated the utility of specifying a hebephilic
    group, at least for research purposes.” 
    Id. Blanchard acknowledged
    that the term “has
    not come into widespread use, even among professionals who work with sex
    offenders.” 
    Id. at 336.
    ¶ 36       The proposal drew vigorous criticism about its scientific validity and
    methodological flaws. Opponents contended that the hebephilia diagnosis would
    dramatically expand or add “to the DSM diagnostic categories of mental disorders
    without any evidence or reasoning that those who would be newly included under the
    mental disorder rubric can be properly categorized as mentally disordered.” Philip
    Tromovitch, Manufacturing Mental Disorder by Pathologizing Erotic Age
    Orientation: A Comment on Blanchard et al. (2008), 38 Archives of Sexual Behav. 328
    (2009); See also Gregory DeClue, Should Hebephilia be a Mental Disorder? A Reply
    to Blanchard et al. (2008), 38 Archives of Sexual Behav. 317 (2009); Joseph J. Plaud,
    Are there “Hebephiles” Among Us? A Response to Blanchard et al. (2008), 38
    Archives of Sexual Behav. 326 (2009); Thomas K. Zander, Adult Sexual Attraction to
    Early-Stage Adolescents: Phallometry Doesn’t Equal Pathology, 38 Archives of
    Sexual Behav. 329 (2009); Allen Frances & Michael B. First, Hebephilia Is Not a
    Mental Disorder in the DSM-IV-TR and Should Not Become One in DSM-5, 39 J. Am.
    Acad. Psychiatry & L. 78, 84-85 (2011) (“the very preliminary studies conducted by a
    few research groups should not be construed to indicate that hebephilia has any solid
    scientific support. Hebephilia is not an accepted mental disorder that can be reliably
    diagnosed”).
    ¶ 37       Ultimately, the proposed diagnosis was recently rejected by the Board of Trustees
    of the American Psychiatric Association for inclusion in the DSM-5. American
    Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders, 5th
    Edition, DSM-5 Paraphilic Disorders 685-705 (2013). The State recognizes the recent
    debate over whether hebephilia is a diagnosable mental condition. Accordingly, we
    conclude that the diagnosis of hebephilia as a mental condition is sufficiently novel for
    purposes of Frye.
    ¶ 38                                      General Acceptance
    ¶ 39      Having determined that the particular testimony is subject to Frye, we next
    consider the issue of its general acceptance in the psychological and psychiatric
    communities. Ill. R. Evid. 702 (eff. Jan. 1, 2011). A court may determine the general
    acceptance in either of two ways: “(1) based on the results of a Frye hearing; or (2) by
    - 10 -
    taking judicial notice of unequivocal and undisputed prior judicial decisions or
    technical writings on the subject.” 
    McKown, 226 Ill. 2d at 254
    ; see also Simons, 
    213 Ill. 2d
    at 531 (we may “consider not only the trial court record but also, where appropriate,
    sources outside the record, including legal and scientific articles, as well as court
    opinions from other jurisdictions”). General acceptance does not require unanimity,
    consensus, or even a majority, but does require something more than a scientific
    principle, technique or methodology that is experimental or of dubious validity.

    199 Ill. 2d
    at 88. The proponent of the evidence bears the burden of
    establishing general acceptance. Ill. R. Evid. 702 (eff. Jan. 1, 2011).
    ¶ 40       We first consider whether we can determine that hebephilia is generally accepted as
    a valid diagnosable mental condition by taking judicial notice of unequivocal and
    undisputed writings on the subject. In the trial court, the State offered no literature in
    response to respondent’s supporting documentation revealing a lack of scientific
    support and widespread opposition to the validity of this particular diagnosis from
    those in the psychology and psychiatric communities.
    ¶ 41       In this court, the State now asserts that, despite the controversy, scientific
    publications unequivocally show that hebephilia is generally accepted as a valid
    diagnosable mental condition. The State relies upon research by Blanchard and others
    that supported Blanchard’s own proposal for the inclusion of the diagnosis in the
    DSM-5. Blanchard, 
    Pedophilia, supra, at 347
    ; Ray Blanchard, The Fertility of
    Hebephiles and the Adaptionist Argument Against Including Hebephilia in DSM-5, 39
    Archives of Sexual Behav. 817, 818 (2010); Robert Prentky & Howard Barbaree,
    Commentary: Hebephilia—A Would-be Paraphilia Caught in the Twilight Zone
    Between Prepubescence and Adulthood, 39 J. Am. Acad. Psychiatry & L. 506, 509
    (2011).
    ¶ 42       Noticeably absent from the State’s discussion is the fact that Blanchard’s proposal
    to include hebephilia as a diagnosis was rejected in the DSM-5. As an undisputed
    authoritative reference manual in the field of psychology and psychiatry, it is necessary
    to address the rejection in our consideration of whether we can take judicial notice that
    hebephilia is generally accepted as the basis for a mental condition. In doing so, we
    recognize that an expert in a civil commitment proceeding is not required to rely upon
    the DSM or establish a consensus in the scientific community to establish that an
    individual has “a mental disorder” as a predicate to civil commitment. The DSM has
    cautioned that psychiatry is not “an exact science.” See American Psychiatric
    Association, Diagnostic and Statistical Manual of Mental Disorders, 5th Edition,
    DSM-5 25 (2013). Nevertheless, numerous experts do apply and rely upon the DSM as
    - 11 -
    an authoritative source to support civil commitment. See, e.g., In re Commitment of
    Fields, 
    2014 IL 115542
    , ¶ 22; In re Commitment of Dodge, 
    2013 IL App (1st) 113603
    ,
    ¶ 9; In re Detention of Ehrlich, 
    2012 IL App (1st) 102300
    , ¶ 25.
    ¶ 43       The DSM diagnostic criteria and classification of mental disorders are applied by
    experts to legitimize a diagnosis as being grounded at some level in sound scientific
    principles. See, e.g., 
    Hendricks, 521 U.S. at 360
    (the diagnosis of pedophilia, what the
    “psychiatric profession itself classifie[d] as a serious mental disorder,” helped
    legitimize the diagnosis and distinguish between a dangerous sexual offender whose
    mental abnormality subjects him to civil commitment from the dangerous, but, typical,
    recidivist who is more properly dealt with through the criminal laws). As the DSM
    recognizes, “when the presence of a mental disorder is the predicate for a subsequent
    legal determination (e.g., involuntary civil commitment), the use of an established
    system of diagnosis enhances the value and reliability of the determination.” American
    Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders, 5th
    Edition, DSM-5 25 (2013).
    ¶ 44       Indeed, despite the State’s attempt to distance itself now from the DSM in assessing
    general acceptance, the State relied upon the experts’ use of the DSM to establish
    general acceptance before the trial court. The State argued “[t]he methodology in
    question is the use of the DSM-IV-TR to make a diagnosis and that is generally
    accepted.” The State asserted that the DSM is an “an authoritative reference manual
    that has long gained general acceptance by professionals who assess sexually violent
    offenders.”
    ¶ 45       Most importantly, the experts in this case relied upon the DSM to support their
    opinion that respondent has a valid diagnosable mental condition. Regardless of the
    terminology and labels used by the experts, Dr. Fogel acknowledged that the diagnosis
    the experts relied upon at trial in evaluating respondent mirrored the proposal by
    Blanchard to expand the diagnosis of pedophilia to cover sexual attraction to early
    pubescent youngsters. See Blanchard, 
    Pedophilia, supra
    . As illustrated by the
    materials presented by respondent, the proposal appears to have had more critics than
    supporters. Its rejection for inclusion in the very authoritative manual upon which the
    State sought to rely in the trial court to establish general acceptance raises more
    questions than it settles. The conflicting literature and the DSM lead us to conclude that
    we cannot take judicial notice of the general acceptance of the hebephilia diagnosis.
    ¶ 46       Alternatively, the State maintains that the issue of general acceptance has been
    resolved in prior judicial decisions. In support, it cites cases that have admitted a
    - 12 -
    paraphilia NOS diagnosis, but where the expert specified a target or preference other
    than hebephilia as a basis for civil commitment. See, e.g., In re Detention of
    Lieberman, 2011 IL App (1st) 090796, ¶ 53 (stating that the diagnosis of “paraphilia
    NOS, nonconsent has been the basis for numerous probable cause or sexually violent
    person findings in this state and other jurisdictions”); In re Detention of Stenzel, 
    827 N.W.2d 690
    , 702 (Iowa 2013) (paraphilia NOS, nonconsent); In re D.H., 
    797 N.W.2d 263
    , 266 (Neb. 2011) (same).
    ¶ 47       With respect to the paraphilia NOS cases cited by the State, we find these cases do
    not provide a basis for this court to take judicial notice that the specifically diagnosed
    condition here is generally accepted. The experts in this case did not rely on merely a
    paraphilia NOS diagnosis but, rather, identified a specific sexual attraction to early
    adolescent males. Part of the debate here involves whether that diagnosis fits within the
    rubric of paraphilia NOS or whether the paraphilia NOS diagnosis is being misused in
    this context.
    ¶ 48       Additionally, the State cites other cases in which experts have relied upon a
    paraphilia diagnosis specifically related to sexual attraction to early adolescents as a
    basis for civil commitment, but where the court has not subjected the diagnosis to a
    Frye hearing. See, e.g., In re Commitment of Hardin, 
    2013 IL App (2d) 120977
    , ¶ 9
    (diagnosed with paraphilia, NOS with a preference for young teenage girls); In re
    Commitment of Curtner, 
    2012 IL App (4th) 110820
    , ¶ 7 (diagnosed with hebephilia,
    described as a sexual disorder whereby the person is aroused by pubescent females); In
    re Care & Treatment of Williams, 
    253 P.3d 327
    , 330 (Kan. 2011) (diagnosed with
    paraphilia NOS, with hebephilia tendencies). As has been repeatedly observed in the
    context of Frye, relying solely on prior judicial decisions to establish general
    acceptance can be a “hollow ritual” if the underlying issue of scientific acceptance has
    not been adequately litigated. (Internal quotation marks omitted.) Simons, 
    213 Ill. 2d
    at
    537.
    ¶ 49       Furthermore, neither Illinois case that has addressed the admissibility of a
    paraphilic diagnosis under a Frye analysis specifically concerned the particular
    paraphilia diagnosed here. See In re Detention of Melcher, 
    2013 IL App (1st) 123085
    ,
    ¶¶ 60-61 (paraphilia, NOS sexually attracted to nonconsenting females otherwise
    known as a paraphilic disorder related to rape); In re Detention of Hayes, 2014 IL App
    (1st) 120364, ¶ 35 (relying on Melcher to establish that it was appropriate to take
    judicial notice that paraphilia NOS, nonconsent is generally accepted). Notably, in
    holding that the diagnosis of paraphilia NOS, nonconsent met the Frye standard, these
    cases relied upon McGee v. Bartow, 
    593 F.3d 556
    (7th Cir. 2010). After describing the
    - 13 -
    diagnosis as a paraphilic disorder related to rape, and reviewing the relevant literature,
    the court in McGee concluded, “the diagnosis of a paraphilic disorder related to rape is
    not so unsupported by science that it should be excluded absolutely from consideration
    by the trier of fact.” 
    McGee, 593 F.3d at 580
    . As this case does not involve the same
    diagnosis, these cases do not provide a basis for this court to take judicial notice that the
    particular diagnosis in this case is generally accepted.
    ¶ 50       Additionally, the State cites federal cases brought pursuant to the Adam Walsh
    Child Protection and Safety Act of 2006 (18 U.S.C. § 4248 (2006)) in which the
    respondents were diagnosed with hebephilia. See United States v. Caporale, 
    701 F.3d 128
    (4th Cir. 2012); United States v. Carta, 
    592 F.3d 34
    (1st Cir. 2010). In those cases,
    the courts considered whether the diagnosis was legally sufficient to support a finding
    that hebephilia constituted a “serious mental illness, abnormality, or disorder” under
    the federal statute, and not the scientific acceptance of the diagnosis in the mental
    health community. 
    Caporale, 701 F.3d at 136-37
    ; 
    Carta, 592 F.3d at 39-40
    . The circuit
    courts were not asked to rule on the admissibility of the expert’s testimony and, if they
    were, the courts would be held to a different standard under the Federal Rules of
    Evidence. See Daubert v. Merrell Dow Pharmaceuticals, Inc., 
    509 U.S. 579
    (1993).
    ¶ 51       We are also particularly mindful that all of these opinions were issued prior to the
    court having the opportunity to address the impact of the current status of the DSM, and
    its consideration and rejection of this proposed diagnosis as a specific category of
    paraphilia or as an extension of pedophilia. Thus, we find that these cases do not
    represent the unequivocal or undisputed viewpoint necessary for us to take judicial
    notice here. As the State conceded at oral argument, where the court has an insufficient
    basis to determine general acceptance, a Frye hearing is necessary. McKown, 
    226 Ill. 2d
    at 254.
    ¶ 52                                          CONCLUSION
    ¶ 53       In sum, we hold that the diagnosis of hebephilia is subject to Frye. Additionally, we
    hold that this court has an inadequate basis to determine whether this diagnosis has
    gained general acceptance in the psychological and psychiatric communities, and that
    this determination cannot be resolved on judicial notice alone. As explained, we do not
    purport to decide the issue of whether the diagnosis has been generally accepted.
    Rather, we affirm the judgment of the appellate court, which remanded the case to the
    circuit court for a Frye hearing to determine if hebephilia is a generally accepted
    - 14 -
    diagnosis in the psychiatric and psychological communities and, if necessary, for a new
    trial.
    ¶ 54      Appellate court judgment affirmed.
    ¶ 55      Cause remanded.
