In a Nutshell

Women accept casual sex offers from strangers at a rate of 0% while men accept at 75%, as shown in the Clark and Hatfield study. Removing courtship requirements through sperm donor selection reveals the same mate preferences persist when people can purely optimize for desired genetic traits. Women refuse more harshly than men because they face greater physical risk, receive more unwanted approaches, and interpret low-value suitors as insulting their mate value.

Andrew Thomas conducted a study examining women's stated preferences for sperm donors. The discussion highlights how typical mate selection requires going through a courtship phase or being seduced, which means people optimize for two different things: the genes their child receives and the traits that make them want to get into bed with someone.

When the seduction requirement is removed, as in sperm donor selection, people can purely optimize for desired traits in their children. Interestingly, the same mate preferences emerge in this context as in actual social interactions.

The Clark and Hatfield study involved attractive men and women approaching random people on a college campus on a nice day. The approachers would say they had noticed the person and found them attractive, then ask one of three questions:

Would you go out with me tonight?
Would you come up to my room?
Would you go to bed with me?

Both men and women were asked by the opposite sex. For the first question about going on a date, there was no sex difference in the original study, with roughly 50% of both men and women saying yes. Replication studies found men were somewhat more likely to say yes than women.

For the second question about coming up to the room, approximately 67% of men said yes in the first study, which was actually higher than the date acceptance rate. Women's acceptance rate dropped to about 6%.

For the third question about going to bed together, 75% of men said yes while exactly 0% of women said yes.

The manner of refusal differed significantly between men and women. The 25% of men who declined were generally polite. Some mentioned being busy or meeting their fiancée but asked for a rain check. In contrast, women who refused were not polite at all. They reacted with disbelief and indignation, and none apologized or requested a rain check.

Two main factors explain the differences in response and refusal styles. First, there is an average difference in interest in casual sex. Men are more interested in casual sex, making them more likely to be flattered by the request. Women traditionally receive far more approaches and must frequently reject advances, making such requests less novel and flattering for them.
