People Look Alike if We Think They Have Similar Personalities

Posted in neuroscience

The authors add that the research informs fundamental scientific understanding of how face recognition works in the brain, suggesting that not only a face’s visual cues but also prior social knowledge plays an active role in perceiving faces.


Summary: Knowledge of an individual’s personality can influence the perception of a face’s identity and bias it toward unrelated people or identities, researchers report.

Do Vladimir Putin and Justin Bieber look alike? They do if you think they have similar personalities, shows a new study by a team of psychologists.

Its findings, which appear in the journal Cognition, reveal that knowledge of a person’s personality can influence the perception of a face’s identity and bias it toward unrelated identities. For example, if Vladimir Putin and Justin Bieber, a pair of faces among many tested in the research, have more similar personalities in your mind, then they visually appear more similar to you as well, even if they lack any physical resemblance.
