Who makes more money: nice people or mean people?

Via the WSJ:

A new study finds that agreeable workers earn significantly lower incomes than less agreeable ones. The gap is especially wide for men.

The researchers examined “agreeableness” using self-reported survey data and found that men who measured below average on agreeableness earned about 18% moreâor $9,772 more annually in their sampleâthan nicer guys. Ruder women, meanwhile, earned about 5% or $1,828 more than their agreeable counterparts.

“Nice guys are getting the shaft,” says study co-author Beth A. Livingston, an assistant professor of human resource studies at Cornell University’s School of Industrial and Labor Relations.
