People who think their opinions are superior to others are most prone to overestimating their relevant knowledge and ignoring chances to learn more

Here is an excerpt:

Finally and more promisingly, the researchers found some evidence that belief superiority can be dented by feedback. If participants were told that people with beliefs like theirs tended to score poorly on topic knowledge, or if they were directly told that their score on the topic knowledge quiz was low, this not only reduced their belief superiority, it also caused them to seek out the kind of challenging information they had previously neglected in the headlines task (though the evidence for this behavioural effect was mixed).

The studies all involved participants accessed via Amazon’s Mechanical Turk, allowing the researchers to work with large samples of Americans for each experiment. Their findings mirror the well-known Dunning-Kruger effect – Kruger and Dunning showed that for domains such as judgments of grammar, humour or logic, the most skilled tend to underestimate their ability, while the least skilled overestimate it. Hall and Raimi’s research extends this to the realm of political opinions (where objective assessment of correctness is not available), showing that the belief your opinion is better than other people’s tends to be associated with overestimation of your relevant knowledge.

You don’t have a right to believe whatever you want to

Here is the conclusion:

Unfortunately, many people today seem to take great licence with the right to believe, flouting their responsibility. The wilful ignorance and false knowledge that are commonly defended by the assertion ‘I have a right to my belief’ do not meet James’s requirements. Consider those who believe that the lunar landings or the Sandy Hook school shooting were unreal, government-created dramas; that Barack Obama is Muslim; that the Earth is flat; or that climate change is a hoax. In such cases, the right to believe is proclaimed as a negative right; that is, its intent is to foreclose dialogue, to deflect all challenges; to enjoin others from interfering with one’s belief-commitment. The mind is closed, not open for learning. They might be ‘true believers’, but they are not believers in the truth.

Believing, like willing, seems fundamental to autonomy, the ultimate ground of one’s freedom. But, as Clifford also remarked: ‘No one man’s belief is in any case a private matter which concerns himself alone.’ Beliefs shape attitudes and motives, guide choices and actions. Believing and knowing are formed within an epistemic community, which also bears their effects. There is an ethic of believing, of acquiring, sustaining, and relinquishing beliefs – and that ethic both generates and limits our right to believe. If some beliefs are false, or morally repugnant, or irresponsible, some beliefs are also dangerous. And to those, we have no right.
