Facial Impressions Are Predicted by the Structure of Group Stereotypes

Impressions of other people's faces (e.g., trustworthiness) have long been thought to be evoked by morphological variation (e.g., upturned mouth) in a universal, fixed manner. However, recent research suggests that these impressions vary considerably across perceivers and targets' social-group memberships. Across 4,247 U.S. adults recruited online, we investigated whether racial and gender stereotypes may be a critical factor underlying this variability in facial impressions. In Study 1, we found that not only did facial impressions vary by targets' gender and race, but also the structure of these impressions was associated with the structure of stereotype knowledge. Study 2 extended these findings by demonstrating that individual differences in perceivers' own unique stereotype associations predicted the structure of their own facial impressions. Together, the findings suggest that the structure of people's impressions of others' faces is driven not only by the morphological variation of the face but also by learned stereotypes about social groups.

Automated summary

This study found that people's impressions of others' faces are influenced not only by facial morphological variation, but also by stereotypes related to social groups. Individual differences in perceivers' stereotype associations play a role in shaping their facial impressions. The variability in facial impressions is not only linked to the gender and race of the target, but also to the structure of stereotype knowledge held by the perceivers.
