Cleanliness or Dirtiness?

This post at the Improbable Research blog offers an interesting perspective. Let me quote an author of the studies that the post discusses:

In two studies we investigated the association between physical cleansing and moral and immoral behavior in real- life situations. In Study 1, after a workout at the gym, participants cheated more after taking a shower than before taking one. In the second study participants donated more money to charity before rather than after they bathed for religious purification.

Hmmmm....
