Not only do general intelligence and academic education fail to protect us from various cognitive errors; smart people may be even more vulnerable to certain kinds of foolish thinking. Intelligent and educated people are less likely to learn from their mistakes, for instance, or take advice from others. And when they do err, they are better able to build elaborate arguments to justify their reasoning, meaning that they become more and more dogmatic in their views. Worse still, they appear to have a bigger ‘bias blind spot’, meaning they are less able to recognise the holes in their logic.
