The physical attractiveness stereotype is a tendency to assume that people who are physically attractive also possess other desirable personality traits. Stereotyping is the process by which people draw inferences about others based on knowledge of the categories to which they belong. Physical attractiveness can have a significant effect on how people are judged in terms of employment or social opportunities, friendship, sexual behavior, and marriage. In many cases, humans attribute positive characteristics, such as intelligence and honesty, to attractive people without consciously realizing it. Physically attractive individuals are regarded more positively and accurately in first impressions. Additionally, the physical attractiveness stereotype will bias an observer's opinions and decisions when comparing people of different attractiveness levels. One study noted a positive correlation between physical appearance and wages. More attractive people are, on average, more likely to be employed and have a higher wage than their normal counterparts. According to this study, the estimated effects of the interviewer rating, generally, have a larger impact on men than on women, while self-ratings (of attractiveness) have a larger effect on women than on men. However, in this study, the rating from others (in this case, the interviewer) has a larger effect than self-rating. "The wage effects of attractiveness are nonlinear for men, which implies that wage punishment for unattractiveness is larger than wage premium for attractiveness and linear for women." Another study wanted to answer the question if individuals would associate higher job stability with attractive people. The results showed that they did in fact favor their hypothesis. Those who were deemed less attractive were correlated to having much lower job stability compared to attractive individuals. It also highlighted how higher-salary jobs were also associated with the more attractive individuals. In some instances, physical attractiveness is distinct from sexual attraction; humans may regard the young as attractive for various reasons, for example, but without sexual attraction. History The physical attractiveness stereotype was first formally observed in a study done by Karen Dion, Ellen Berscheid, and Elaine Walster in 1972. Study participants, all students, were told by the experimenters that they would be tested on how well they could "read" a person after seeing a single photo of them, and that their performance would be compared to individuals that had been trained to be able to read a person based on body language and other interpersonal skills. The subjects were then given three envelopes
