power will lead you to eat more cookies and chew with your mouth open

This is pretty fascinating:

"A particularly amusing study—undertaken by Keltner, Gruenfeld, and another colleague—shows that giving people just a little more power than their colleagues causes them to eat more cookies, chew with their mouths open, and leave more crumbs." -- Bob Sutton, writing for Business Week

More info from the study:

The experimenters "examined whether power would produce socially inappropriate styles of eating. In same-sex groups of 3 individuals, 1 randomly chosen individual (the high-power person) was given the role of assigning experimental points to the other 2 on the basis of their contributions to written policy recommendations concerning contentious social issues. After group members discussed a long and rather tedious list of social issues for 30 minutes, the experimenter arrived with a plate of five cookies. This procedure allowed each participant to take one cookie and provided an opportunity for at least 1 participant to comfortably take a second cookie, thus leaving one cookie on the plate. Consistent with the prediction, high-power individuals were more likely to take a second cookie. Coding of the videotaped interactions also revealed that high-power individuals were more likely to chew with their mouths open and to get crumbs on their faces and on the table."

I have crumbs all over myself right now, and I have no power over anyone anymore. So make of that what you will.
