However, what Dove is suggesting is not actually true. The evidence from psychological research suggests instead that we tend to think of our appearance in ways that are more flattering than are warranted. This seems to be part of a broader human tendency to see ourselves through rose colored glasses. Most of us think that we are better than we actually are — not just physically, but in every way.
The most direct evidence that the Dove commercial is misleading comes from the work of Nicholas Epley of the University of Chicago and Erin Whitchurch of the University of Virginia. In a series of studies, Epley and Whitchurch showed that we see ourselves as better looking than we actually are. The researchers took pictures of study participants and, using a computerized procedure, produced more attractive and less attractive versions of those pictures. Participants were told that they would be presented with a series of images including their original picture and images modified from that picture. They were then asked to identify the unmodified picture. They tended to select an attractively enhanced one.
Epley and Whitchurch showed that people display this bias for themselves but not for strangers. The same morphing procedure was applied to a picture of a stranger, whom the study participant met three weeks earlier during an unrelated study. Participants tended to select the unmodified picture of the stranger.
