If you’ve spent much time on a college campus in the last couple of years, you may have seen a lush quad and neo-gothic cloister interrupted by fliers screaming “Yes Means Yes!” According to recent research on sexual consent among college students, you wouldn’t be wrong to wonder whom the unsubtle slogan really serves.

Part of a campaign to counteract a perceived rape culture, “Yes Means Yes!” stands for an accepted definition of “affirmative consent” to sexual activity. But, in light of findings from San Jose State professor Jason Laker and colleague Erica Boas, it’s unclear whether this definition’s role in campus policy has any influence on students’ attitudes and actions.
