This book looks at a number of studies, mostly by Ariely himself, all of which examine the circumstances under which people lie and cheat. What he finds is that cheating is rampant and bounded; or to put it another way, we all cheat a little bit. Ariely then pushes the limits of that, to figure out under what conditions we are more or less likely to cheat, and further to see if there are particular individuals who are particularly prone to lying or cheating. The book is funny, easy to read, and extremely relevant to anyone interested in morality, law, finance, religion, administration, politics, or any other profession in which people find themselves tempted to bend the rules once in awhile.
