People with more radical beliefs performed similarly on the task to moderates, but they tended to give higher confidence ratings when they had made incorrect choices than moderates did. Radicals’ confidence in correct answers was similar to that of moderates.
A second stage of the study assessed how participants took in new evidence. After making a judgment on the dots task, participants were shown another set of dots as ‘bonus’ information about the correct answer, before making their confidence judgment. If they had made an incorrect choice, the next set of dots should have weakened their confidence in their choice – which it did for moderates, but not as much for people with radical political views.
“An important point is that our findings held true among participants with radical views at either end of the political spectrum – radicalism appears to reflect a cognitive style that transcends political inclinations,” co-author of the study, Professor Ray Dolan (Wellcome Centre for Human Neuroimaging and Max Planck UCL Centre for Computational Psychiatry & Ageing Research), said.
While it's admirable to stand up for your beliefs, it's important to empathize with others too, at least if we want to fix our problems (of which we have many).
