Beliefs about which sex lies more or is better at lying can have subtle but widespread effects on human interactions, yet little is known about such beliefs. In Study 1, an American sample of participants (N = 407, ages 18–64) completed a 12-item survey on perceptions of sex differences in deception. In Study 2, a Korean sample (N = 197, ages 19–58) completed the same survey. Men from both cultures and Korean women perceived no difference regarding which sex tells more white (i.e., relatively harmless or low-stakes) lies. American women perceived that women tell more white lies. Women from both cultures and American men perceived that men tell a greater number of serious (i.e., nonwhite or high-stakes) lies. Korean men perceived no difference regarding which sex tells a greater number of serious lies. Both sexes from both countries reported a perception that (1) men are more likely to lie about height, income, and sexual infidelity, (2) women are more likely to lie about weight and age, and (3) women are better at lying. The findings were mixed regarding perceptions about emotional infidelity. Results are interpreted in light of sex-different challenges to mating and parenting.

关于哪种性别撒谎更多或更擅长撒谎的信念可能会对人类互动产生微妙但广泛的影响，但人们对这种信念知之甚少。在研究 1 中，美国参与者样本（N = 407，年龄 18-64）完成了一项包含 12 项的调查，内容涉及对欺骗中性别差异的看法。在研究 2 中，韩国样本（N = 197，年龄 19-58）完成了相同的调查。来自两种文化的男性和韩国女性对于哪种性别会撒更多善意（即相对无害或低风险）的谎言没有什么区别。美国女性认为女性会说更多善意的谎言。来自两种文化的女性和美国男性都认为男性会撒更多严重的（即非白人或高风险的）谎言。韩国男性对于哪种性别说的严重谎言较多没有什么区别。两国的男女都报告了这样的看法：(1) 男性更有可能在身高、收入和性不忠方面撒谎，(2) 女性更有可能在体重和年龄方面撒谎，(3) 女性更擅长撒谎。关于情感不忠的看法，调查结果好坏参半。根据性别对交配和养育子女的不同挑战来解释结果。
