Recognizing Strangers | Psychology Today - 0 views

Benoit Monin, assistant professor of psychology at Stanford University, showed college students 80 photos of faces, then asked them which ones they recognized from among the 40 they'd seen in an earlier session. The more attractive the photo (as rated by another group of students) the more likely it was to be recognized—regardless of whether the face had been seen before.

"The face's attractiveness actually changes your perception of your past," in this case, the perception of whether you've seen the face before. The shortcut may lead to errors, but it may also help us manage our busy lives, says Monin. "We tend to like familiar things, so it makes perfect sense that over time we would use liking as a clue to familiarity."

In what he calls the "warm-glow heuristic," people consider their affinity for a specific person or place as an indicator of familiarity. As with other mental shortcuts, people resort to this heuristic when they lack enough data on which to base their decisions.
