We need similar controls for the confirmation bias in the arenas of law, business and politics. Judges and lawyers should call one another on the practice of mining data selectively to bolster an argument and warn juries about the confirmation bias. CEOs should assess critically the enthusiastic recommendations of their VPs and demand to see contradictory evidence and alternative evaluations of the same plan. Politicians need a stronger peer-review system that goes beyond the churlish opprobrium of the campaign trail, and I would love to see a political debate in which the candidates were required to make the opposite case.
Skepticism is the antidote for the confirmation bias.
