[R]esearchers have determined that mirrors can subtly affect human behavior, often in surprisingly positive ways. Subjects tested in a room with a mirror have been found to work harder, to be more helpful and to be less inclined to cheat, compared with control groups performing the same exercises in nonmirrored settings. Reporting in the Journal of Personality and Social Psychology, C. Neil Macrae, Galen V. Bodenhausen and Alan B. Milne found that people in a room with a mirror were comparatively less likely to judge others based on social stereotypes about, for example, sex, race or religion.
“When people are made to be self-aware, they are likelier to stop and think about what they are doing,” Dr. Bodenhausen said. “A byproduct of that awareness may be a shift away from acting on autopilot toward more desirable ways of behaving.” Physical self-reflection, in other words, encourages philosophical self-reflection, a crash course in the Socratic notion that you cannot know or appreciate others until you know yourself.

In a report titled “Mirror, Mirror on the Wall: Enhancement in Self-Recognition,” which appears online in The Personality and Social Psychology Bulletin, Nicholas Epley and Erin Whitchurch described experiments in which people were asked to identify pictures of themselves amid a lineup of distracter faces. Participants identified their personal portraits significantly quicker when their faces were computer enhanced to be 20 percent more attractive. They were also likelier, when presented with images of themselves made prettier, homelier or left untouched, to call the enhanced image their genuine, unairbrushed face. Such internalized photoshoppery is not simply the result of an all-purpose preference for prettiness: when asked to identify images of strangers in subsequent rounds of testing, participants were best at spotting the unenhanced faces.
How can we be so self-delusional when the truth stares back at us? “Although we do indeed see ourselves in the mirror every day, we don’t look exactly the same every time,” explained Dr. Epley, a professor of behavioral science at the University of Chicago Graduate School of Business. There is the scruffy-morning you, the assembled-for-work you, the dressed-for-an-elegant-dinner you. “Which image is you?” he said. “Our research shows that people, on average, resolve that ambiguity in their favor, forming a representation of their image that is more attractive than they actually are.”
