Who may judge a book by its cover?

该项目旨在建立一个模型，说明人们对他人的印象如何以及为什么会有所不同，以及这些印象的准确性。人们很容易从别人的脸形成对别人的印象，而这些印象会影响关键的决定：选举结果、法庭结果和合作伙伴的选择。为了建立这个模型，本项目将采用双胞胎数据，并构建一个心理测量测试来测量面部印象的变化。这项研究有望深入了解社会感知的这一方面，并确定非典型或不准确的面部判断的来源。这适用于卫生领域（识别社会障碍）和安全领域（选择人员）。

This project aims to build a model of how and why people vary in their impressions of others and in the accuracy of these impressions. People readily form impressions of others from their faces and these impressions influence crucial decisions: election results, court case outcomes and partner choices. To build this model, the project will apply twin data and construct a psychometric test to measure variation in facial impressions. The research is expected to lead to insights into this aspect of social perception, and to identify the sources of atypical or inaccurate facial judgements. This has applications in health contexts (to identify social impairment) and in security contexts (for personnel selection).
