You see this all the time in advertisement. A pretty, skinny lady is going to sell more bottled water than an over weight unattractive lady. A buff man is going to see a gym membership easier than a man with a potbelly. You even notice good looking people in TV ads and print when the product has nothing to do with exercise or fitness.
I found it very fascinating that babies looked longer at attractive people regardless of their gender, age and race. Though I do question the theory of "Beauty is in the Eye of the Beholder". I wonder how this comes into play in the Attractiveness Bias. Who's idea of attractiveness are we talking about?
