Is lying and cheating Jewish?

No lying and cheating is not Jewish. It is universal, everyone does it a little, a few people do it a lot.

In the WSJ, to promote his new book, Dan Ariely wrote, "Why We Lie" he explains, "We like to believe that a few bad apples spoil the virtuous bunch. But research shows that everyone cheats a little—right up to the point where they lose their sense of integrity."

Ariely's research shows that nearly everyone cheats and lies if given the opportunity. In his book, The Honest Truth About Dishonesty: How We Lie to Everyone---Especially Ourselves Ariely explains why.

Based on the WSJ write-up, this looks like a good book.
