The NY Times reports on research into moral hypocrisy:
[Does a] hypocrite really believe, in his heart, what he is saying?
Fortunately, we don’t need to get into the fine points of taxes or campaign finances to take a stab at these questions. We can probably get further by looking at some experiments in what psychologists call moral hypocrisy.
This is a more devious form of hypocrisy than what was exhibited by, say, the governor of New York when he got caught patronizing a prostitute. It was obviously hypocritical behavior for a public official who had formerly prosecuted prostitutes and increased penalties for their customers, but at least Eliot Spitzer acknowledged his actions were wrong by anyone’s standards.
The moral hypocrite, by contrast, has convinced himself that he is acting virtuously even when he does something he would condemn in others.
