Dunning-Kruger Syndrome is rampant, and it didn't start with the covid pandemic. How about people who say that global warming isn't happening because we still sometimes have cold weather? Deniers of scientific evidence think that they're smart, and those of us who understand the nuances of science are stupid.
Please post some examples of Dunning-Kruger Syndrome in action that you recall seeing. (It can be text, images, or both.)
REMEMBER: Dunning-Kruger is NOT merely people being stupid; it's people being stupid coupled with a false sense of intellectual superiority.
The bumper sticker pictured below is calling all the world's top scientists stupid!
