In her contribution to our “Sexuality & Gender Studies Now” series, Zoe D. Peterson recounts how affirmative consent policies in college campuses went from being ridiculed as excessive in the early 1990s to a common college policy. Drawing on recent research on these policies, she presents the benefits and shortcomings of affirmative consent—promoting direct and active communication as well as overlooking coerced and uninformed consent, respectively. Peterson concludes with a call for more research on the effects of affirmative consent policies and on ways to address those who ignore the policies.
