Based on a sample of nearly 8,000 college students, this study was undertaken to determine the prevalence of non-heterosexuality using four different measures of sexual orientation: a self-identity measure, an attraction measure, a fantasy measure, and an experiential measure. Over 97% of both males and females labeled themselves as heterosexual, with the proportion of homosexuals and bisexuals combined constituting nearly 3% of the male sample and about 2% of the female sample. Roughly 80-85% of both sexes would be classified as exclusively heterosexual, with about 10% of both sexes having at least half of their sexual fantasies involving same-sex partners. In terms of sexual experiences, about 5% of non-virgin males and 0.5% of non-virgin females reported that all of their experiences had involved same-sex partners. After examining each of the sexual orientation measures separately, we compared them to one another. These comparisons revealed an unsettling number of apparent contradictions in the responses given by individual participants (e.g., participants who stated that they were homosexual but that all of their fantasies involved members of the opposite sex). By eliminating participants who provided these apparent contradictory responses, a post-hoc refined self-identified measure of sexual orientation was created. This refinement had essentially no effect on our estimates of the proportion of college students who were identified as heterosexual or homosexual, thus suggesting that the inconsistencies were largely due to random response error. Boosting our confidence in the post-hoc refined measure, we found that it exhibited slightly stronger links with several established childhood correlates of sexual orientation (such as the enjoyment of collecting dolls and playing dress-up) than was true for the original self-identified sexual orientation.
基于近8000名大学生的样本，本研究采用四种不同的性取向测量方法来确定非异性恋的流行程度：自我认同测量法、吸引力测量法、幻想测量法和经历测量法。超过97%的男性和女性将自己标记为异性恋，同性恋者和双性恋者的比例加起来在男性样本中接近3%，在女性样本中约为2%。大约80 - 85%的男女会被归类为完全异性恋，大约10%的男女至少一半的性幻想涉及同性伴侣。在性经历方面，约5%的非处男和0.5%的非处女报告称他们所有的性经历都涉及同性伴侣。在分别检查了每种性取向测量方法后，我们对它们进行了相互比较。这些比较揭示了个体参与者给出的回答中存在数量惊人的明显矛盾（例如，参与者表示自己是同性恋，但所有幻想都涉及异性成员）。通过剔除给出这些明显矛盾回答的参与者，创建了一种事后 refined 的性取向自我认同测量方法。这种细化对我们对被认定为异性恋或同性恋的大学生比例的估计基本没有影响，因此表明这些不一致主要是由于随机回答误差。增强了我们对事后 refined 测量方法的信心的是，我们发现它与一些已确定的与性取向相关的童年因素（如喜欢收集玩偶和玩换装游戏）的联系比原始的性取向自我认同测量方法略强。
