We think we are better than average at not being biased in thinking that we’re better than average.

This is true especially for people who have studied this subject at college. Thus, the behavioralists neatly infer from the literature that everyone else is biased. Now, surely these are smart, educated people, and they are less biased on simple scientific questions that your average housewife doesn’t know, but there are lots of big issues relating to politics and business strategy that don’t have a monotonic relation between learning and the ability to discern the good. Just look at politics or education, areas subject to a lot of study over the past 50 years, which are hardly more efficient than before all this knowledge arrived. (Source)
