1. This particular study shows that both men and women who watch porn are less likely to support affirmative action for women. The study is fascinating because it shows a decrease in support of affirmative action for women over time if people watch porn, even when controlling for political and religious views. The data indicated that "prior pornography viewing predicted subsequent opposition to affirmative action," but "prior opposition to affirmative action did not predict subsequent pornography viewing."

A second study shows that watching porn correlates to an immediate increase in sexist attitudes, but only in a subgroup of men who are considered low in "agreeableness" (meaning they were generally cold, unfriendly, and hostile). After exposing men and women to hard-core pornography, only men in this subgroup illustrated an increase in sexist attitudes. 

  

The researchers behind this study emphasize that porn does not cause, so much as reinforce, the sexist attitudes apparent in this subgroup. "If these men already have these kinds of beliefs, but they are more dormant, porn appears to prompt these in their conscious minds," Neil Malamuth, a co-author of the study and a psychology professor at UCLA, tells Cosmpolitan. "These men already have these tendencies; porn adds fuel to the fire."
