To me this book closely relates to self-handicapping, a topic that not only we covered in class, but also something that I have come to realize that I have done my entire life. Though on the surface they may not relate, if you look deeper you'll see that these people in the experiments that Ariely did were not only cheating for the monetary reward, they were also cheating for their own person esteem. Much like with self-handicapping the people are giving themselves something to save face, instead of pushing things off and giving themselves an out though, they are preserving their belief of being above average by saying they did above average work on the matrices. These two things are very different in how they are done, but can achieve the same result if someone is seeking the same goal.
All in all, the book can be used by all people to find their own reasons for why they would cheat, and find ways to be honest with others and themselves. It can be used to help the world rid itself of cheaters or, of course it can be used as a guide for cheating, once someone understands that if they distance their conscious from the act of cheating that it becomes easier, then they will become a more effective cheater.
