The (honest) Truth About Dishonesty
In Dan Ariely's new book, The (Honest) Truth About Dishonesty : How We Lie To Everyone - Especially Ourselves, he explores cheating, lies, and human nature by looking at psychology experiments. If you liked the more famous Freakonomics books or those by Malcolm Gladwell, you'll enjoy Dan Ariely, who makes you rethink your "morality" when it comes to cheating and lying - but in a totally entertaining way!
For those of you who shy away from non-fiction, this book (and previous books by the author) is incredibly readable and fun - Ariely is charmingly self-deprecating - and reading him is like hearing stories from an old friend who just happens to be a behavioral economist. If you don't want to commit to reading the entire book, I highly recommened you at least check out Dan Ariely's blog or twitter, where you can get fascinating snippets from the social psychology world in pop form.
