How Have Anthropologists Attempted to Explain the Universality of the Incest Taboo, Including Rare Instances Where Brother-Sister Marriage Is Broadly Favored?
Clearly, incest prevents both. It preserves a limited genetic pool and makes an increase of material possessions through intermarriage all but impossible. Once allocated, the family is an efficient venue of transferring material wealth, as well as transmitting information and messages horizontally (among family members) and vertically (down the generations).
Recent research has found that juvenile female prostitutes more often than not have a history of sexual abuse. A study indicated that nearly 70% of girls who were institutionalized for sexual delinquency or immorality were victims of incest (Pasko, 2010). A common after-effect of incest is negative attitudes towards sex by the victim. As a result of incest negative connotations such as fear, revulsion, and a sense of powerlessness are associated with sex by the victim. However, some of the victims of incest react by becoming overly active sexually.
