Dion et al. (1972) – What is Beautiful is Good

Aim:

To investigate the "halo effect," where people assume that attractive individuals possess more positive personality traits.

Procedure:

• 60 participants (30 male, 30 female) were shown three sets of photographs of individuals who had been pre-rated as physically attractive, average, or unattractive.
• Participants were asked to make judgments about each person in the photograph based solely on their appearance. They rated the individuals on various dimensions such as personality, intelligence, future success, and social desirability.
• Ratings were done using a 6-point scale that assessed multiple traits, including kindness, competence, happiness, and popularity.
• The study design controlled for other factors that might influence how participants rated the photographs, such as the lighting or the context in which the photos were taken. This control helped isolate physical attractiveness as the main factor affecting ratings.

Results:

• Attractive individuals were consistently rated as more successful, socially desirable, and having better personalities than those who were rated average or unattractive.
• The study highlighted the "halo effect" — where physical attractiveness leads to assumptions about other positive qualities.
• The findings showed a strong bias in favor of attractive individuals in terms of perceived competence and likability, even when no other information was available.
