The book is not a complete waste of time, it contains some interesting insights on race in particular and did, at least, explain to me why office chair design has changed in the last five years and also how my reactions to that change – from “that chair looks awful” to “I love sitting in this chair” were, in fact, fairly typical. I also read a lot about a musician I had never heard of (the book attempts to explain why) and an embarrassment for the US Department of Defense.
But essentially the book seems to be a long-winded way of noting that:
- experts often have a near instant gut feeling about things which turn out to be right;
- evolution means we are equipped to make decisions in a split second so we can survive but that decision-making ability is also automatically applied to many areas where the decision is not about survival; and
- often these rapid decisions are good and helpful, but often they are not – in particular even those of us who abjure racism will make decisions conditioned by a sub-conscious racial prejudice.
