Most of us discovered pretty early that life isn’t always fair, but
that doesn’t mean the reality of injustice can’t surprise you again and
again. Take a new study on pay and personality, for example. It reveals that "agreeable men,” or nice guys in everyday language, earn 18 percent less than jerks.
Using three different, large data sets, researchers from Cornell, Notre Dame and Western Ontario compared the earning of people who rated themselves as more or less agreeable. What makes a person agreeable? Study co-author Beth Livingston recently explained the quality to NPR :
Agreeableness is a complex personality trait and it
really encompasses people who are kinder, more trusting, more
cooperative. And those who are more disagreeable tend to be more
competitive, arrogant, manipulative and they tend to value their
relationships less than those who are agreeable.
