Stop; I don't care to talk to someone who promotes fraudulent citations.

They aren't  fraudulent.  Nice try

"There is no Dunning-Kruger." (Psychology Today, 2020)

Yup one publication which doesn't prove it doesn't exist

Indeed not, but John's claim was that "most people with a psychology degree know the dunning-kruger effect doesn't exist."

As Boru pointed out here:

According to https://www.ndnu.edu/how-long-does-it-ta...20country.

There are about 3.5 million people in the US with degrees in psychology. For John’s statement to be verified, he would need to provide evidence that at least 1 750 001 of those people don’t believe that the Dunning-Kruger effect exists.

Now of course John did not specify only the US, so even this would not properly evidence his comical sweeping hubris. And so far all he has offered is the claim, and one article, and from a source he claims is fraudulent when it runs an article he doesn't like, oh dear.
