We’re always trying to figure out why people support Trump, why Republicans vote against their own interests, and why such folks loudly orate their views at the drop of a hat. Maybe Ph.D. neuroscience candidate Kate Fehlhaber can give us a clue. She cites a study that shows incompetent people are too incompetent to evaluate their own incompetence.


“… ‘illusion of confidence’ is now called the ‘Dunning-Kruger Effect’, and describes the cognitive bias to inflate self-assessment.

To investigate this phenomenon in the lab, Dunning and Kruger designed some clever experiments. In one study, they asked undergraduate students a series of questions about grammar, logic and jokes, and then asked each student to estimate his or her score overall, as well as their relative rank compared to the other students. Interestingly, students who scored the lowest in these cognitive tasks always overestimated how well they did – by a lot. Students who scored in the bottom quartile estimated that they had performed better than two-thirds of the other students!…”

Who’s Writing?

JoAnn Chateau

JoAnn likes progressive politics and loves the canines. She writes fiction about Chester, the Alpha Bichon -- with a dash of humor and a dab of Poli-Sci. Her views and insights are tinted by a former profession in Counseling, Christian theological studies, and training in Library and Information Science. Retired now, JoAnn enjoys the creative life.

Chester

Chester is a scruffy little Bichon dog, with a congenial Napoleon Complex, and stars in "The Chester Chronicles." He sometimes reports independent Canine News -- NO corporate treats accepted, NO corporate bias. Woof!

Graffiti Girl

Graffiti Girl (GG) is curator at JoAnnChateau.com. She's progressive to the core, and easily blown away by serendipity and/or good food. (OK, GG is really JoAnn.) GG's posts signal that news or content from another website is a "must-see" and "must-remember."
