You are not so smart

The book, You Are Not So Smart: Why You Have Too Many Friends on Facebook, Why Your Memory Is Mostly Fiction, and 46 Other Ways You're Deluding Yourself by David McRaney, is an easy read. It reviews many cognitive biases and compares what we innately think compared to what we really do. This material is familiar if you read similar type of books such as Think fast and think slow or authors such as Dan Ariely.
