Disagreement on Disagreement

"The most popular indicators here seem quite different from what media, academia, and government use to decide who to believe in the context of disagreements. And if these poll participants were representative and honest about what actually persuades them, then these results suggest that speakers should adopt quite different strategies if their priority is to persuade audiences. Instead of collecting formal credentials, adopting middle-of-road positions, impugning rival motives, and offering long complex arguments, advocates should instead offer bets, adopt rational talking styles and take many tests, such as on IQ, related facts, and rival arguments."
