While some studies defy expectations, others confirm long-held stereotypes.
In a paper that will appear in a forthcoming issue of the Journal of Personality and Social Psychology titled "Do Nice Guys -- And Gals -- Really Finish Last? The Joint Effects of Sex and Agreeableness on Income," for example, researchers found that the answer to that timeworn question was a resounding "yes."
Results indicated that disagreeable people -- men in particular -- earn substantially more in the workforce than their agreeable colleagues.
But the study affirmed another long-held belief as well: in case you were in doubt, gender double standards still exist in the workplace.
