EVIDENCE THAT PORN REDUCES RAPE
ANTHONY D'AMATO, NORTHWESTERN SCHOOL OF LAW - The incidence of rape in the United States has declined 85% in the past 25 years while access to pornography has become freely available to teenagers and adults. The Nixon and Reagan Commissions tried to show that exposure to pornographic materials produced social violence. The reverse may be true: that pornography has reduced social violence. . . The decline [is] steeper than the stock market crash that led to the Great Depression. . . There were 2.7 rapes for every 1,000 people in 1980; by 2004, the same survey found the rate had decreased to 0.4 per 1000 people. . .
Official explanations for the unexpected decline include (1) less lawlessness associated with crack cocaine; (b) women have been taught to avoid unsafe situations; (c) more would-be rapists already in prison for other crimes; (d) sex education classes telling boys that "no means no." But these minor factors cannot begin to explain such a sharp decline in the incidence of rape. There is, however, one social factor that correlates almost exactly with the rape statistics. The American public is probably not ready to believe it. My theory is that the sharp rise in access to pornography accounts for the decline in rape. The correlation is inverse: the more pornography, the less rape. It is like the inverse correlation: the more police officers on the street, the less crime.
The pornographic movie "Deep Throat" which started the flood of X-rated VHS and later DVD films, was released in 1972. Movie rental shops at first catered primarily to the adult film trade. Pornographic magazines also sharply increased in numbers in the 1970s and 1980s. Then came a seismic change: pornography became available on the new internet. Today, purveyors of internet porn earn a combined annual income exceeding the total of the major networks ABC, CBS, and NBC. "Deep Throat" has moved from the adult theatre to a laptop near you.
National trends are one thing; what do the figures for the states show? From data compiled by the National Telecommunications and Information Administration in 2001, the four states with the lowest per capita access to the internet were Arkansas, Kentucky, Minnesota, and West Virginia. The four states with the highest internet access were Alaska, Colorado, New Jersey, and Washington. . .
While the nationwide incidence of rape was showing a drastic decline, the incidence of rape in the four states having the least access to the internet showed an actual increase in rape over the same time period. This result was almost too clear and convincing, so to check it I compiled figures for the four states having the most access to the internet. Three out of four of these states showed declines (in New Jersey, an almost 50% decline). Alaska was an anomaly: it increased both in internet access and incidence of rape. However, the population of Alaska is less than one-tenth that of the other three states in its category.
