A lot more, it turns out. The ugly truth, according to economics professors Daniel Hamermish and Jeff Biddle, is that plain people earn 5 to 10 percent less than people with above-average looks. And those of above-average looks earn 3 to 8 percent less than people considered "attractive."
In their report "Beauty, Productivity and Discrimination," Hamermish and Biddle found that the probability of a male lawyer earning a partnership directly correlates with how handsome he is. And height matters, too. Another study showed that tall people earn considerably more money throughout their careers, with each inch adding almost $800 dollars a year in pay.
Experts say that human beings are hard-wired to respond more favorably to attractive people. Good-looking men and women are generally judged to be more talented, kind, honest and intelligent than their less attractive counterparts.
Even babies will look more intently and longer at prettier faces. They don't know what "pretty" is, what they're responding to is the symmetry in a person's face. If both sides look equal and balanced.
But don't rush off for the next round of 'Extreme Makeover' just yet. According to the experts, attractiveness has more to do with how you carry yourself and the energy you exude. Anyone can increase their attractiveness to others if they maintain eye contact, act upbeat, dress well, smile and listen.
