So it comes down to this: between little changes in our facial characteristics over time and a reverse image in the mirror, it's no surprise that we don't identify ourselves in images. Place yourself in front of a mirror. Take a snapshot of your reflection with your phone. Turn your camera around and take a "selfie." If you look closely, you'll see some fuzziness to the image and some minor color differences from one side of your face to the other. That's because when we look at ourselves in a mirror or photograph our faces, we're seeing through the eyes of another person. Little changes can make a big difference when it comes to self-awareness and personal identity. For example, if as children we were told over and over again that we looked like our mother or father, then it's not surprising if later on we assume that about ourselves too. The same thing goes for our reflections. Since we were kids, have been told over and over again that we look like one famous person or another, it's no wonder if we believe it's true of ourselves too. The more we know about psychology and neuroscience, the more we realize how much of who we think we are is actually due to chance events and similarities to others. In fact, research shows that we tend to overestimate the similarity of our traits to those of people we know well and underestimate it for people we don't.
