"Hooking-up"--engaging in no-strings-attached sexual behaviors with uncommitted partners--has become a norm on college campuses, and raises the potential for disease, unintended pregnancy, and physical and psychological trauma. The primacy of sex in the evolutionary process suggests that predictions derived from evolutionary theory may be a useful first step toward understanding these contemporary behaviors. This study assessed the hook-up behaviors and attitudes of 507 college students. As predicted by behavioral-evolutionary theory: men were more comfortable than women with all types of sexual behaviors; women correctly attributed higher comfort levels to men, but overestimated men's actual comfort levels; and men correctly attributed lower comfort levels to women, but still overestimated women's actual comfort levels. Both genders attributed higher comfort levels to same-gendered others, reinforcing a pluralistic ignorance effect that might contribute to the high frequency of hook-up behaviors in spite of the low comfort levels reported and suggesting that hooking up may be a modern form of intrasexual competition between females for potential mates.
“勾搭”——与关系不确定的伴侣进行无附加条件的性行为——已成为大学校园中的一种常态，而且增加了疾病、意外怀孕以及身心创伤的可能性。进化过程中性的首要地位表明，从进化理论得出的预测可能是理解这些当代行为的有用的第一步。本研究评估了507名大学生的勾搭行为及态度。正如行为进化理论所预测的：男性对各类性行为都比女性更为坦然；女性正确地认为男性更为坦然，但高估了男性实际的坦然程度；男性正确地认为女性坦然程度较低，但同样高估了女性实际的坦然程度。男女两性都认为同性别的其他人更坦然，强化了一种多元无知效应，这可能导致尽管报告的坦然程度较低但勾搭行为仍频发，并表明勾搭可能是女性之间为争夺潜在配偶而进行的种内竞争的一种现代形式。
