Ian Anson in The Conversation:
Over the past five years, I have studied the phenomenon of what I call “political overconfidence.” My work, in tandem with other researchers’ studies, reveals the ways it thwarts democratic politics.
Political overconfidence can make people more defensive of factually wrong beliefs about politics. It also causes Americans to underestimate the political skill of their peers. And those who believe themselves to be political experts often dismiss the guidance of real experts.
Political overconfidence also interacts with political partisanship, making partisans less willing to listen to peers across the aisle.
The result is a breakdown in the ability to learn from one another about political issues and events.
