A series of experiments conducted by University of Minnesota researcher Katherine Vohs show that money not only causes people to work harder toward their own goals--but also to distance themselves from others.
When primed with pictures or thoughts of money, people acted more self-sufficiently, distancing themselves from new acquaintances and preferring to work alone, Vohs found. Given tasks such as word puzzles, these subjects were not only less likely to help others, but also took longer to request help.
