大规模研究发现脸宽高比与行为倾向无关
Facial Width-to-Height Ratio Does Not Predict Self-Reported Behavioral Tendencies
- 基于13.7万样本，用55项心理量表检验脸宽高比与行为关系
- 未发现脸宽高比与性格、冲动性、公平感等行为倾向显著关联
- 挑战小样本研究结论，适合关注心理学可重复性的读者
越来越多研究将脸宽高比（fWHR）与反社会或攻击性行为倾向相关联。然而这些研究多基于小样本实验室实验，统计功效较低。本研究在包含137,163名参与者的大型样本中重新检验了fWHR与行为倾向的关系。行为倾向通过55项成熟的心理测量量表评估，涵盖智力、大五人格各维度及子特质、冲动性、公平感、寻求刺激兴趣、自我监控、印象管理以及生活满意度等。结果表明，fWHR与任一自报行为指标均无显著关联，质疑了以往fWHR与行为关联结论在小样本和特定实验环境下外推的合理性。
原文摘要 · Abstract (English)
A growing number of studies have linked facial width-to-height ratio (fWHR) with various antisocial or violent behavioral tendencies. However, those studies have predominantly been laboratory based and low powered. This work reexamined the links between fWHR and behavioral tendencies in a large sample of 137,163 participants. Behavioral tendencies were measured using 55 well-established psychometric scales, including self-report scales measuring intelligence, domains and facets of the five-factor model of personality, impulsiveness, sense of fairness, sensational interests, self-monitoring, impression management, and satisfaction with life. The findings revealed that fWHR is not substantially linked with any of these self-reported measures of behavioral tendencies, calling into question whether the links between fWHR and behavior generalize beyond the small samples and specific experimental settings that have been used in past fWHR research.
