"Some descriptions of actresses in pornography have included attributes such as drug addiction, homelessness, poverty, desperation and being victims of sexual abuse," they said. "Some have made extreme assertions, such as claiming that all women in pornography were sexually abused as children. Stereotypes of those involved in adult entertainment have been used to support or condemn the industry and to justify political views on pornography, although the actual characteristics of actresses are unknown because no study on this group of women has been conducted."
