The power of first impressions. I’m Bob Hirshon and this is Science Update.
Our first impressions of people can be very influential, even after we’ve gotten to know them. Among the researchers who study this is University of Toronto social psychologist Nick Rule. He’s found, for example, that once people judge strangers’ faces as either trustworthy or untrustworthy, it’s hard for contradictory information to override that impression.
NICK RULE (University of Toronto):
So even though they might know that some person is a thief, and some person is a saint, so to speak, that will carry less weight in sort of how they process the person than how they look, based on their appearance.
He’s seen similar results when participants guessed a person’s sexual orientation, even from photos of just their eyes. Rule says when they’re under time pressure, people are especially prone to rely on their first impressions, and require more time and prompting to recall more objective information.
