There is accumulating evidence that heterosexual men exhibit tolerance to their partners' same-sex infidelity. The current study examined such tolerance in the Chinese ( N = 949) and the British ( N = 305) cultural contexts. Consistent with the predictions derived from an evolutionary framework, across different cultural settings, men exhibited higher tolerance than women to their partners' same-sex infidelity. In addition, if they had to choose, men were considerably more likely than women to prefer their partners to cheat with an individual of the same than of the opposite sex. Participants were also more tolerant of infidelity involving their short-term than their long-term partners. Moreover, men who preferred same-sex attraction in women were more tolerant to the same-sex infidelity of their female partners than men who did not share these preferences. Finally, men and women who experienced same-sex attractions indicated higher tolerance to infidelity. The implications of these finding for the evolution of same-sex attraction in women were further discussed.
越来越多的证据表明，异性恋男性对其伴侣的同性不忠表现出宽容。当前的研究在中国（N = 949）和英国（N = 305）文化背景下考察了这种宽容度。与从进化框架得出的预测一致，在不同文化背景下，男性对其伴侣的同性不忠表现出比女性更高的宽容度。此外，如果必须做出选择，男性比女性更有可能宁愿伴侣与同性而非异性出轨。参与者对涉及短期伴侣而非长期伴侣的不忠行为也更为宽容。此外，比起没有这些偏好的男性，对女性的同性吸引力有偏好的男性对其女性伴侣的同性不忠行为更为宽容。最后，经历过同性吸引的男性和女性对不忠行为表现出更高的宽容度。这些发现对女性同性吸引的进化的影响将进一步讨论。
