Maestripieri et al. provide an important service in highlighting prosocial biases toward attractive people from a cross-disciplinary perspective. Here I comment on the conceptual and critical side of their review of evolutionary psychology studies. I propose that further work should be focused on understanding the role of signaling in prosocial behavior.

作为性信号的亲社会行为

Maestripieri 等人。在从跨学科的角度突出对有吸引力的人的亲社会偏见方面提供重要服务。在这里，我评论了他们对进化心理学研究的评论的概念和批判性方面。我建议进一步的工作应该集中在理解信号在亲社会行为中的作用。
