I'm starting to think that all Malcolm Gladwell books are the same thing - a rather ordinary/non-controversial statement about life which is padded with pretty neat examples and then praised as revolutionary, thus selling millions of copies. 
 Main thesis is that social ability is a greater guarantee of success than mere intelligence. Well of course sociability can help. But life is not as simple as the pop-culture philosophers theorize. 
 I am also distrustful of the means by which 'success' is measured. These terms do not seem to be properly defined. For intelligence, Gladwell relies on IQ, which is an unreliable and discredited method for this job, at best. 
 The main idea of the book is somewhat interesting, but the reasoning simply does not stand up to scrutiny. I wonder if it is my own paranoia, but I guessed that there is an undercurrent of anti-intellectualism in his books. Reason is not enough - your mere instinct and sociability can supersede them. 
 Given 2 stars because the basic idea is not wholly false.
