You never get a second chance, the saying goes, to make a first impression. It turns out you may
not even get that. Within 50 milliseconds of seeing someone’s face, you unconsciously make decisions that will influence your interactions.
Those 50 milliseconds are difficult to overcome, says University of Toronto psychology professor Nicholas Rule. “Every time you see someone, even if it’s someone you really know, you’re making that first impression again.”
You can influence a first impression by wearing glasses, which imply intelligence, or facial piercings, which suggest rebelliousness, but research shows that a face can retain the same characteristics no matter how it’s presented.
