Married couple Bret Weinstein and Heather E. Heying are, along with Eric Weinstein, the leading exemplars of the Intellectual Dark Web so it's no surprise they are also exemplars of the Dunning-Kruger effect. As described in the Forbes article The Dunning-Kruger Effect Shows Why Some People Think They're Great Even When Their Work Is Terrible:
Coined in 1999 by then-Cornell psychologists David Dunning and Justin Kruger, the eponymous Dunning-Kruger Effect is a cognitive bias whereby people who are incompetent at something are unable to recognize their own incompetence. And not only do they fail to recognize their incompetence, they’re also likely to feel confident that they actually are competent.
Bret and Heather appear to be having a competition on Twitter today to determine which one of them is the biggest exemplar of Dunning-Kruger.
First Bret tells the International Chess Federation how chess works:
Then Heather tells Mathematical Association of America how math works.
The exile of Bret Weinstein and Ms. Heying from Evergreen State brought them to the attention of a national audience that might have come for the controversy but has stayed for their fascinating insights about subjects including evolution and gender...
“Our friends still at Evergreen tell us that the protesters think they destroyed us,” Ms. Heying said. “But the truth is we’re now getting the chance to do something on a much larger scale than we could ever do in the classroom.”
The quote also demonstrates the way IDW grifters portray their perceived enemies - Heying makes a claim about what the protestors think, not based on evidence, but rather based on what "our friends tell us."
