“We see what we want to see,” my grandmother used to say. This insight visited me recently after I ran across the mall chasing a woman I thought was my cousin. It wasn’t, as it turned out, but I didn’t realize that until after I had puffed up behind her, bopped her amiably on the shoulder and cried out, “Boo!”

How was it possible, I thought in retrospective embarrassment, to so wrongly misidentify someone I know so well? Empirically my experience was all too common. I’d been thinking about my cousin a few moments before and saw the woman through the lens of those thoughts. We often project our life’s associations onto the faces of strangers. Constantly—if mostly unconsciously—we familiarize them with learned stereotypes. If we are wise, we learn to take caution with our assumptions. We recognize this innate fallibility, and most of the time it doesn’t matter very much.
