Gladwell's book is based on the idea that most decisions can and are made unconsciously and correctly almost instantly. Don't misunderstand, the reason why this can and does happen is largely due to training and certain universals. If a person spends their entire life working in art history, there is a good chance they might recognize a forgery instinctively before they are able to communicate why they consciously believe a work is a forgery. This is due to an abundance of training. Likewise, it is suggested that all humans have certain facial expressions in common and some people can instinctively recognize these expressions and thus learn information about people without ever actually having to meet them or interact with them (such as just seeing a silent video of a person). While the information is very interesting in this book, I'm also concerned about it. It seems like people could hear about these theories and decide that instincts will serve them better than thinking through various processes (like how Republicans appeal to gut reactions to promote their agenda despite evidence to contradict their claims). Additionally, there seems to be an awful lot of examples of where these instincts go horribly, horribly wrong, to the point where I feel the examples used are rather hit or miss, in that you can look at any situation and find evidence to support this theory and find evidence of where this theory has gone wrong through "inappropriate" use of instinct. (And since this is my gut feeling about the situation I must be 100% correct.) There is also a section in the text wherein he discusses how the mind can be manipulated, for example how making margarine the same color as butter allows the mind to think it taste the same as butter. But later on he gives the example of how people’s biases made them think that women do not play classical music as well as men. But based on his earlier example, isn’t it then possible the people’s minds did actually make them hear women playing worse than men because their minds have been conditioned and not simply due to some silly bias? He seemed to have missed his own concept.
