Ironically, my first instinct seeing this book was that it would probably be a collection of subjectitvely picked research to back some unconvincing hypothesis of overstated importance.  Well of course part of that was true, after all Gladwell is a journalist and not a scientist.  However, in general, he does a great job in describing the research and its relevance to our everday lives.Blink focuses on 2 seperate but related concepts.  The first is that of "time slicing", which demonstrates how important information can be encoded in a very short period of time.  Most of Gladwell's examples are socioloical, and the most striking of which was research which aimed to predict whether married couples would get divorced after analyzing a single conversation with them.The other concept is how the brain acts subconsciously to certain stimulus.  Gladwell's proposal is that if we can recognize this power of the brain we'd make the world a much better place and all sorts of other grand things.  So, although not perfect, this is a good and interesting book.
