Just finished reading 'The (Honest) Truth About Dishonesty: How We Lie to Everyone--Especially Ourselves'. The book explores the psychology of lying, cheating and corruption, and the factors (both internal and external) that either increase or decrease it (as well as how we can exploit these factors to get less cheating in our own lives, and society in general). It was quite good. I've written an executive-style summary of the book at newbooksinbrief.wordpress.com
Cheers,
