Why Saints Sin And Sinners Get Saintly

To many, New York Gov. Eliott Spitzer's fall from grace seemed to make no sense at all. But a new Northwestern University study offers provocative insights that possibly could relate to why the storm trooper of reform -- formerly known as the Sheriff of Wall Street -- seemingly went from saint to sinner overnight.

The study suggests that people with ample moral self-worth in one aspect of their lives can slip into immorality or opposite behavior in other areas -- their abundant self-esteem somehow pushing them to balance out all that goodness.

Other studies have shown the moral-cleansing effect, but this new Northwestern model shows that the cleansing also has to do with restoring an ideal level of moral self-worth. In other words, when people operate above or below a certain level of moral self-worth, they instinctively push back in the opposite direction to reach an internally regulated set point of goodness.
