Fascinating stuff - Rated
I've been bumbling around in the area of behavioural economics/finance for a bit as it has some bearing on my day job. As a result I have developed a geeky interest in the area of mistakes in reasoning, biases etc. The book is a really good introduction to the area and very clearly-written.

It basically gives you a much better insight into some of the things you have probably already noticed (for example, people only seem to notice/value information that confirms what they already think). Aside from the fact that it's a genuinely fascinating area, you might also glean some information that actually helps you in the real world. I was struck by the point that partners tend to notice when their other half does (or doesn't do) something, that causes them pain, but not when the reverse. Hence I will notice if the Mrs doesn't stack the dishwasher, because it annoys me, but won't register when she does do it, so I will tend to take from this that she "never" stacks the dishwasher.

Usefully it also takes the insights from wonky reasoning and applies them to "questionable" beliefs - ESP, 'alternative medicine' etc. And you might learn a bit more about how to tell a good story!

Definitely worth a read. The other book recommended alongside this - Inevitable Illusions - is less good, but also worth a look. It gets into the interesting area of probability (and how bad we are at estimating and understanding it).

YOU'VE GOT TO READ THIS. - Rated
Maybe you think you know that when you believe something you only count the things that fit and discount the things that don't.

I can guarantee that after you read this book, the next time you say something like "most joggers seem to be female nowadays" you'll realise that this judgment was based on a sample of only two people! and hence meaningless. Well worth reading.

Everybody should read this book! - Rated
In an age where science affects almost every aspect of modern life it is surprising that the number of people who believe "weird things" appears to be on the increase.

This book is an excellent guide on how to critically think about everything that you see and hear in your life. I found the authors section on confirmation bias very useful, as it shows how people almost always approach a subject from a biased view and try to GATHER information to SUPPORT that view without even realising they are being biased.

This book is very important for a contemporary culture that has many influential people, of all age ranges, and all levels of intelligence trying to make people believe the most mindboggling nonsense imaginable.

If you here a theory, it doesn't matter who says it, use your own intelligence to critically analyse it. And remember that many people, refuse to believe theories that are quite sound and by trying to sway public opinion, they attack the person saying the theory rather than looking at what they are saying; this is also known as a smear campaign.

This book is a great start for anyone looking for TRUTH in their life rather than clinging onto any belief like a comfort blanket.

If only I had read it years ago! - Rated
I can scarcely recommend this book highly enough to anyone interest in widespread errors of reasoning. Working in the same branch of social science as Thaler, Tversky and Kahneman, the author manages to explain very clearly how we fall into reasoning traps, probably because of the environment in which our brains evolved.

Although Gilovich's case studies are interesting (belief in ESP, and belief in extreme forms of "alternative" medicine), it's the theoretic part of the book which really stands out as being of benefit to the reader. Anyone who reads a newspaper, watches the television news, votes or invests in the financial markets ought to take the time to read this book.
