Theories in both evolutionary and social psychology suggest that a positive correlation should exist between facial attractiveness and general intelligence, and several empirical observations appear to corroborate this expectation. Using highly reliable measures of facial attractiveness and IQ in a large sample of identical and fraternal twins and their siblings, we found no evidence for a phenotypic correlation between these traits. Likewise, neither the genetic nor the environmental latent factor correlations were statistically significant. We supplemented our analyses of new data with a simple meta-analysis that found evidence of publication bias among past studies of the relationship between facial attractiveness and intelligence. In view of these results, we suggest that previously published reports may have overestimated the strength of the relationship and that the theoretical bases for the predicted attractiveness-intelligence correlation may need to be reconsidered.

在大量具有遗传信息的样本中，智力和面部吸引力之间没有关系。

进化心理学和社会心理学理论都表明，面部吸引力和一般智力之间应该存在正相关关系，一些实证观察似乎证实了这一预期。通过对同卵双胞胎和异卵双胞胎及其兄弟姐妹的大样本进行高度可靠的面部吸引力和智商测量，我们没有发现这些特征之间存在表型相关性的证据。同样，遗传和环境潜在因素的相关性都不具有统计显着性。我们通过简单的荟萃分析补充了对新数据的分析，该分析发现了过去关于面部吸引力和智力之间关系的研究中存在发表偏见的证据。鉴于这些结果，我们认为之前发表的报告可能高估了这种关系的强度，并且可能需要重新考虑预测的吸引力-智力相关性的理论基础。
