Humans prefer cockiness to expertise

EVER wondered why the pundits who failed to predict the current economic crisis are still being paid for their opinions? It’s a consequence of the way human psychology works in a free market, according to a study of how people’s self-confidence affects the way others respond to their advice.

The research, by Don Moore of Carnegie Mellon University in Pittsburgh, Pennsylvania, shows that we prefer advice from a confident source, even to the point that we are willing to forgive a poor track record. Moore argues that in competitive situations, this can drive those offering advice to increasingly exaggerate how sure they are. And it spells bad news for scientists who try to be honest about gaps in their knowledge

…With complex but politicised subjects such as global warming, for example, scientific experts who stress uncertainties lose out to activists or lobbyists with a more emphatic message.
