"With these data from a wide variety of countries and cultures, we can better evaluate the thesis that an abundance of sexual explicit material invariably leads to an increase of illegal sexual activity and eventually rape (e.g., Liebert, Neale, & Davison, 1973; MacKinnon, 1989; Morgan, 1980). Similarly we can now better reconsider the conclusion of the Meese Commission that there exists "a causal relationship to antisocial acts of sexual violence and . . . unlawful acts of sexual violence (Meese, 1986; pp. 326)." Indeed, the data we report and review suggests that the thesis is myth and, if anything, there is an inverse causal relationship between an increase in pornography and sex crimes." --The Effects of Pornography: an international perspective by Milton Diamond
