but think they know the most: study
The study involved genetically modified organisms, where there is little political bias to confuse the issue.
The more extreme the opposition, Fernbach and his co-authors found, the less people knew about the science and genetics, but the more their “self-assessed” knowledge — how much they thought they knew — increased.
“If somebody is well calibrated, those two things should be pretty highly correlated: If I know how much I know, then if I know a little I should say I know a little, and if I know a lot I should say I know a lot,” Fernbach explained. “Therefore there should be a high correlation between self-assessed and objective knowledge.
“And indeed, that’s actually true for the people who are moderate, or people who have the attitude that is consistent with the scientific consensus,” he said.
However, as people become more extreme, that relationship degrades and flips so that people who think they know more actually know less.
