I recently read Bruce Schneier's latest book , "Liars and Outliers". This is not a how-to book. It won't make your code more secure. I doubt that it would serve as a manual on human interactions for extraterrestrials. Nor is it likely to improve a bank loan officer's percentage of good loans, or an eBay buyer's choice of sellers, or your ability to detect email phishing or a corporation whose accountants have cooked the books. But it might shape your understanding of all that stuff. Liars & Outliers is a look at how trust works in society, with passing references to neuroscience, economics and game theory. Along with a description of how the negative feedback of societal pressure is supposed to work is an explanation of why it doesn't work so well on-line and with large corporations.
