This page records only what the paper and its published record state. Biography beyond the cited work is not given here.

Key papers

What is beautiful is good (1972), with Berscheid and Walster. The study asked whether physically attractive people, both male and female, are assumed to possess more socially desirable personality traits than unattractive people, and whether they are expected to lead better lives, for example as more competent husbands and wives and as more successful workers. It also looked at whether the sex of the person judging and the sex of the person judged changed the answer. The authors reported a "what is beautiful is good" stereotype along the attractiveness dimension, with no interaction between the sex of the judge and the sex of the person being judged. They discussed what such a stereotype might mean for how people come to see themselves and for the course of social interaction.

Key ideas

The central idea is that appearance is the most visible thing about a stranger, and that people use it to infer qualities they cannot see. That is the halo effect in its plainest social form: one liked feature spreads into judgements of character and fortune.

Later work refined the claim. A 1991 meta-analysis led by Alice Eagly found the stereotype real but moderate on average, largest for judgements of social competence and close to zero for integrity and concern for others. In 2024, a study led by Aditya Gulati found that beauty filters raised ratings of intelligence, trustworthiness, sociability and happiness for the same faces, which suggests the stereotype has carried over to edited images.
