Psychology Today: The Dunning-Kruger Effect May Help Explain Trump's Support
A new study suggests some people grossly overestimate their political knowledge.
In the past, some prominent psychologists have explained President Donald Trump’s unwavering support by alluding to a well-established psychological phenomenon known as the “Dunning-Kruger effect.” The effect is a type of cognitive bias, where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they don’t have enough knowledge to know they don’t have enough knowledge. This simple but loopy concept has been demonstrated dozens of times in well-controlled psychology studies and in a variety of contexts. However, until now, the effect had not been studied in one of the most obvious and important realms—political knowledge.
A new study published in the journal Political Psychology, carried out by the political scientist Ian Anson at the University of Maryland Baltimore County, not only found that the Dunning-Kruger effect applies to politics, it also appears to be exacerbated when partisan identities are made more salient. In other words, those who score low on political knowledge tend to overestimate their expertise even more when greater emphasis is placed on political affiliation.
Anson told PsyPost that he became increasingly interested in the effect after other academics were discussing its potential role in the 2016 U.S. presidential election on social media. “I follow a number of political scientists who marveled at the social media pundit class’ seeming display of ‘Dunning-Kruger-ish tendencies’ in their bombastic coverage of the election.” However, speculation by scientists does not always translate into statistically-significant findings, so Anson began thinking of ways to experimentally test what he described as a “very serious accusation.”

He thinks he is such the expert. I love him like life itself, but when it comes to politics, he's as dumb as a damn rock. And it's willful ignorance on steroids.
I've begged my mother to break the remote control so that he can't watch Fox (Hannity in particular), but she won't do it. But I may when I go home this Christmas. Oh, that trip's gonna be so much fun.
