The Report of the Commission on Obscenity and Pornography390
-412 ( 1970). For a
discussion of earlier studies indicating "a division of thought [among behavioral scientists] on
the correlation between obscenity and socially deleterious behavior", Memoirs v.
Massachusetts, supra, 383 U.S., at 451, 86 S.Ct., at 993
, and references to expert opinions that
obscene material may induce crime and antisocial conduct, see id., at 451-453, 86 S.Ct., at
Clark, J., dissenting). As Mr. Justice Clark emphasized: "While erotic stimulation
caused by pornography may be legally insignificant in itself, there are medical experts who
believe that such stimulation frequently manifests itself in criminal sexual behavior or other
antisocial conduct. For example, Dr. George W. Henry of Cornell University has expressed the
opinion that obscenity, with its exaggerated and morbid emphasis on sex, particularly abnormal and perverted practices, and its unrealistic presentation of sexual behavior and attitudes, may induce antisocial conduct by the average person. A number of sociologists think
that this material may have adverse effects upon individual mental health, with potentially
disruptive consequences for the community.

"Congress and the legislatures of every State have enacted measures to restrict the distribution of erotic and pornographic material, justify these controls by reference to evidence that
antisocial behavior may result in part from reading obscenity." Id., at 452-453, 86 S.Ct., at
994-995 (footnotes omitted).
