5. Silbert and Pines (1981)

The experiment: Researchers interviewed 200 San Francisco prostitutes.  The interviews touched on history of sexual abuse, including rape and child sexual abuse.

The results:

• 178 of 200 prostitutes reported child sexual abuse.

• 193 of 200 prostitutes reported being raped as adults.

• In other words, only 7 of these 200 prostitutes had never been raped or molested.

• Without being asked about porn, 24% of the rape survivors spontaneously added that their attacker had specifically cited his porn use during the crime.

• This was also true of 22% of the child sexual abuse survivors.
