I can't stop reading Malcolm Gladwell (I always mistakenly type Malcolm Macdowell.huh.)! But like in the past few books that I read by him, I wasn't so much interested in the big picture, or the theory he is trying to present. I can't quit reading because the anecdotes are so interesting. The experiments and all those interesting people. Its interesting. Maybe it's because of my background in psychology (well, bachelor of arts) that I find it all so interesting.
So this book is about the snap judgements and the power of thinking without thinking. Says so right there on the cover. It talks about how our initial impressions can be very helpful and how we subconsciously perceive things can result to good decisions. There is of course a downside in which we judge instantaneously based on faulty preconceptions. Therefore, we should train ourselves to be able to distinguish which impressions are useful and which are not.
I think that's what it was about. Like I said, I didn't really pay that much attention to the main thesis, just on the individual anecdotes. What struck with me though, was that to be able to get reliable first impressions, or to be able to think without thinking, you need, like all other things, to practice.
