People who invoke the Dunning-Kruger effect are usually guilty of it by their own definition.
A pet peeve of mine is when someone brings up the Dunning-Kruger effect. Anytime I see it I know some dumb smug shit is about to follow. People overwhelmingly use it erroneously in regards to intelligence. The irony is they’re committing the same sin they’re accusing others of by not using the term correctly.
“Among laypeople, the Dunning–Kruger effect is often misunderstood as the claim that people with low intelligence are more confident in their knowledge and skills than people with high intelligence. According to psychologist Robert D. McIntosh and his colleagues, it is sometimes understood in popular culture as the claim that "stupid people are too stupid to know they are stupid". But the Dunning–Kruger effect applies not to intelligence in general but to skills in specific tasks.”
