The vast majority of women in modern societies use facial cosmetics, which modify facial cues to attractiveness. However, the size of this increase remains unclear--how much more attractive are individuals after an application of cosmetics? Here, we utilised a 'new statistics' approach, calculating the effect size of cosmetics on attractiveness using a within-subjects design, and compared this with the effect size due to identity--that is, the inherent differences in attractiveness between people. Women were photographed with and without cosmetics, and these images were rated for attractiveness by a second group of participants. The proportion of variance in attractiveness explained by identity was much greater than the variance within models due to cosmetics. This result was unchanged after statistically controlling for the perceived amount of cosmetics that each model used. Although cosmetics increase attractiveness, the effect is small, and the benefits of cosmetics may be inflated in everyday thinking.
现代社会中的绝大多数女性都使用面部化妆品，这些化妆品会改变面部的吸引力线索。然而，这种吸引力增加的幅度仍不明确——使用化妆品后，个人的吸引力会提高多少呢？在这里，我们采用了一种“新统计”方法，通过受试者内设计计算化妆品对吸引力的效应量，并将其与因身份导致的效应量进行比较——也就是说，人与人之间吸引力的固有差异。分别拍摄了女性化妆和不化妆的照片，然后由另一组参与者对这些照片的吸引力进行评分。身份因素所解释的吸引力差异比例远大于化妆品因素在模型中所导致的差异。在对每个模特使用的化妆品量进行统计控制后，这一结果并未改变。尽管化妆品会增加吸引力，但这种效果很小，而且在日常认知中，化妆品的作用可能被夸大了。
