Cognition of Weight Gain

A friend sent me this article which looks at how people make estimates of certain things and shows that the brain ignores some information, which developed in times when survival depended on fast decisions. It causes people to do things like underestimate the calories in a meal, for example, which may be a factor in the current obesity epidemic. Plus humans evolved when food was scarce, so the instinct was to eat everything in front of us. Interesting!
