Opinion
Joaquin Ruiz, Jr., appeals his conviction of a single count of lewd conduct with a child. (Pen. Code, § 288, subd. (a).)
Facts
The 10-year-old victim, Catherine W., was a neighbor and friend of Ruiz’s granddaughter. Catherine, looking for her friend, found Ruiz baby *1243 sitting for the family’s two younger children. Ruiz invited her into the house to watch television with him and the children. Catherine testified that Ruiz spoke to her about sex, had her sit with him on a chair where he touched her sexually and put her hand on his penis.
Ruiz does not contend that there was insufficient evidence to support his conviction; rather he claims that he was denied a fair trial because the court refused to permit his expert witness to testify that Ruiz did not share certain characteristics commonly shared by pedophiles.
I
The Exclusion of the Offered Testimony of the Defense’s Expert Witness
The defense sought to introduce evidence that Ruiz did not share characteristics commonly associated with persons suffering from pedophilia. The defense made an offer of proof that Dr. Paul S. D. Berg, a psychologist with extensive experience in examining and treating pedophiles, would testify that there are two primary types of pedophiles, one who becomes “fixed . . . stuck on urges that have to do with sexual pleasure with children,” and a “regressive” type which, upon undergoing some unusual stress, decompensates and acts out sexually. Dr. Berg had examined Ruiz and had administerеd to him several standard psychological tests, including the Minnesota multiphasic personality inventory (MMPI), the Millon clinical multiaxial inventory (MCMI), a sentence completion test and the Bender gestаlt test. Dr. Berg stated that the tests administered were not designed to determine if the subject being tested was a pedophile or sexual deviant, but further stated that the results of the tests, plus his own examination, сaused him to form the opinion that Ruiz did not “fit the typical pattern of those people who are known and diagnosed and treated as pedophiles.” “I can describe what he’s like psyсhologically, I can give you opinions about mental functioning, I can certainly tell you whether or not he fits in or outside of categories; but I regard the specific question as a legal detеrmination and not a psychological one.” Dr. Berg further stated that barring an admission by a subject that he was a pedophile, he would never be able to say whether or not a particular рatient was a pedophile, “but I can tell you, again, based on my clinical experience, that they tend to produce certain kinds of profiles, and other folks do not.” The court, citing

It is now settled that psychological opinions based upon personal examination and an analysis of accepted psychological tests, such as the

MMPI and MCMI, may be admitted as character evidence tending to show that an individual was or was not likely to have committed a particular act, and that the admissibility of such evidence need not be tested under the

standard.

John W., supra,
In the present case there was no evidence that the tests administered by Dr. Berg are used in the scientific community for any purpose other than to “identify, predict and treat” a patient’s emotional problems. There was no evidence that Dr. Berg questioned Ruiz’s factual statements, or that he questioned anything Ruiz related. Additionally, Dr. Berg testified that the tyрes of pedophilia he described were but the two “primary” types. Accordingly, the reliability of the material upon which Dr. Berg based his opinion seems questionable, as does its relevancе to the issue of guilt. Nonetheless, the tests at issue are similar to those administered in People v. Stoll and, like that of the expert in Stoll, Dr. Berg’s opinion was based not only on the test results, but on a personal examination. It follows that in the present situatiоn, Ruiz was entitled to have Dr. Berg state his opinion that Ruiz was not a sexual deviant, or was not a pedophile, or was not likely to have committed the charged acts.
Dr. Berg apparently had no intention of stating an opinion on any of these matters. Rather, he planned to testify that Ruiz did not have the psychological characteristics of a person suffering from pedophilia; i.e., that he did not match the profile of a pedophile.
Stoll
does not hold that such “profile” evidence is admissible. Rather, the court carefully limited its holding, emphasizing that the psychiatrist in that casе had indicated that “no psychological ‘profile’ entered into his diagnosis.” Instead, the psychiatrist would emphasize that the defendant showed “ ‘low indication for antisocial or aggressive behavior,’ ” implying that she “is ‘unlikely’ to commit the charged acts or any serious crime.”

v.
Stoll, supra,
Nonetheless, we see little reason to distinguish between the material underlying the expert’s opinion in
Stoll
and the type оf “profile” evidence underlying Dr. Berg’s opinion in the present case. It is difficult to comprehend how a psychologist or psychiatrist could opine that a particular person is not a sеxual deviant or pedophile without comparing the results of the expert’s examination (including the results of any standardized test administered) with the results of similar tests on persons who were sexual deviants or pedophiles; i.e., with profile evidence. Indeed, the court in
Stoll
left open the possibility that profile evidence might be admissible. “We are not persuaded that juries are incapable of evaluating properly presented references to psychological ‘profiles’ and ‘syndromes.’ ”
(People
v.
Stoll, supra,
Still, it is not enough to determine that certain material—here, profile evidence—might be admissible. Evidence Code section 801, subdivision (b) *1246 requires that the matter underlying an expert’s opinion be “of a type that reasonably may be relied upon by an expert in forming an opinion upon the subject to which his testimony relates.” Thus there must be somе showing that the material on which the expert bases his or her opinion—here the profiles of the primary types of pedophile—is reliable.
As discussed, ante, there was no such showing in the present casе. There was no evidence that the scientific community had developed any standard profile of a pedophile. Indeed, Dr. Berg explained that the tests he used were not designed to elicit that information and had not been standardizеd against a population group of pedophiles. Dr. Berg said that the disorder usually manifests itself in persons who have become fixated on children or on persons who have experiеnced some recent stress, but there was no showing that Dr. Berg was stating anything other than his personal opinion, nor was there any showing that his personal opinion in such matters was reliable.
It is not, howevеr, unlikely that the inadequacy of the showing resulted more from the confusing state of the law than from the inability of Ruiz to establish facts meeting the requirements of

Notes
“[A]dmissibility of expert testimony based upon the application of a new scientific technique traditionally involves a two-step process: (1) the
reliability of the method
must be established, usually by expert testimony, and (2) the witness furnishing such testimony must be properly
qualified as an expert to give an opinion
on the subject.”
