Despite the commonly held belief that homosexual males and females are more creative compared to heterosexuals, empirical studies on homosexuality and its relationship to creativity have been sparse, often with questionable methodology and very small sample sizes, reporting mixed findings. No study till date has explored the associations described above in a large population-based and genetically informative sample. Here, we examined such potential associations between sexual orientation and creative achievement in several different domains (music, writing, dance, visual arts, science, invention, and theater) using a large cohort of 4494 Swedish twins (of which 7.5 % were not exclusively heterosexual). Data were analyzed for the sexes separately as well as pooled. Results showed significant associations between sexual orientation and two of the creative domains-theater and writing-with non-heterosexuals being more creative in these domains. In all other domains, no significant differences were found between the non-heterosexual and heterosexual groups. Findings from co-twin control analyses suggested that the significant associations may not be causal in nature (i.e., homosexual orientation leads to higher creativity) but due to shared liability. However, we lacked power to differentiate between shared genetic and shared environmental influences. Results and potential implications are discussed critically.
尽管人们普遍认为同性恋男性和女性比异性恋者更具创造力，但关于同性恋及其与创造力关系的实证研究却很稀少，研究方法往往存疑，样本量也非常小，研究结果不一。迄今为止，尚无研究在基于大规模人群且具有遗传信息的样本中探讨上述关联。在此，我们使用一个由4494对瑞典双胞胎组成的大型队列（其中7.5%并非完全是异性恋），研究了性取向与几个不同领域（音乐、写作、舞蹈、视觉艺术、科学、发明和戏剧）的创造性成就之间的潜在关联。对数据分别按性别以及合并后进行了分析。结果显示，性取向与两个创造性领域——戏剧和写作——之间存在显著关联，非异性恋者在这些领域更具创造力。在所有其他领域，非异性恋组和异性恋组之间未发现显著差异。同卵双胞胎对照分析的结果表明，这些显著关联可能并非因果关系（即同性恋取向导致更高的创造力），而是由于共同的易感性。然而，我们没有能力区分共同的遗传影响和共同的环境影响。对结果及其潜在影响进行了批判性讨论。
