Physical attractiveness can have various effects. A survey conducted by London Guildhall University of 11,000 people showed that those who subjectively describe themselves as physically attractive earn more income than others who would describe themselves as less attractive.[40] People who described themselves as less attractive earned, on average, 13% less than those who described themselves as more attractive, while the penalty for being overweight was around 5%. It is important to note that other factors such as self-confidence may explain or influence these findings as they are based on self-reported attractiveness as opposed to any sort of objective criteria; however, as one's self-confidence and self-esteem are largely learned from how one is regarded by his/her peers while maturing, even these considerations would suggest a significant role for physical appearance. One reason that unattractive people might not have friends is that they have low self-esteem.
