Bloomberg reports on How to Humble a Wing Nut.
"For a positive answer, consider an intriguing study by Philip Fernbach, a University of Colorado business school professor, and his colleagues. Their central finding is that if you ask people to explain exactly why they think as they do, they discover how much they don’t know -- and they become more humble and therefore more moderate."
"The results were stunning. On every issue, the result of requesting an explanation was to persuade people to give a lower rating of their own understanding -- and to offer a more moderate view on each issue. In a follow-up experiment, Fernbach and his co-authors found that after being asked to explain their views, people were less likely to want to give a bonus payment to a relevant advocacy group.
Interestingly, Fernbach and his co-authors found no increase in moderation when they asked people not to “describe all the details you know” about the likely effects of the various proposals, but simply to say why they believe what they do. If you ask people to give reasons for their beliefs, they tend to act as their own lawyers or public relations managers, and they don’t move toward greater moderation. The lesson is subtle: What produces an increase in humility, and hence moderation, is a request for an explanation of the causal mechanisms that underlie people’s beliefs."
