Humans judge faces in incomplete photographs as physically more attractive

Area of Science:

• Psychology
• Social Psychology
• Cognitive Science

Background:

• Individuals often form judgments about others' attractiveness based on incomplete facial data.
• Perceived attractiveness is linked to assumptions about health, wealth, and sociability.

Purpose of the Study:

• To investigate the hypothesis that people make positive inferences to fill gaps in facial information when judging beauty.
• To determine if incomplete facial information leads to biased attractiveness judgments.

Main Methods:

• Seven experiments were conducted involving participants judging the attractiveness of human faces.
• Facial attractiveness was evaluated using both complete and incomplete photographs.

Main Results:

• Participants rated faces in incomplete photographs as more physically attractive compared to complete ones.
• This positivity bias was consistent across different types of incompleteness and primarily affected aesthetic judgments.
• The bias was more pronounced in male participants, specific to human faces, and involved holistic processing, particularly for atypical faces.

Conclusions:

• The human tendency to infer positive qualities into incomplete facial information significantly impacts beauty judgments.
• This research sheds light on the cognitive mechanisms underlying attractiveness perception and social inference.
