    The Dunning Kruger-effect is a shaky concept. Recent studies seem to have disproved it in some ways.

        Plot with green points is Dunning Kruger data. It’s hardly correlated.

          Using this plot as a statistical argument against the idea of Dunning Kruger is pretty Dunning Kruger.

          It’s a scatter plot with hella dense overlap and no density indicator, and a best-fit line that doesn’t match the visual skew. Different ranges and scales on the axes are wonky as hell and make it hard to follow a 1:1 reference line. Try tracing a mental line from (75,75) to (150,150) and it looks much cleaner.

          It seems to show subjective vs. evaluated IQ results, which mostly shows people generally think they’re far above average. There’s clearly a statistically significant positive correlation in the trend of modest magnitude.

          More importantly though, it’s a bit of a weird thing to tie to Dunning Kruger: The plot tells us something about how well people can guess how “cognitively gifted” they are relative to peers, but that’s not a reasonable proxy for how people might self-evaluate on a skill-based or knowledge-based domain.

          E: and I went looking for the source and that’s fake, simulated data you’re presenting as real there lol https://en.wikipedia.org/wiki/Dunning–Kruger_effect#Statistical_and_better-than-average_effect

      It tends to explain why entry level programmers act the way they do. Like when I graduated I was definitely on the peak of mount stupid but as I learned more I realized how little I knew. I did not externalize this as I was just trying to make iy through my days, however I have seen some entry levels absolutely fuck things up because they thought they were geniuses. It was exactly like that bell curve where idiots and experts do the same simple thing but mediocre people do the most complicated thing possible with 5 layers of abstraction.

        Just because it explains an experience, doesn’t mean it’s statistically true in a deep way. I would tend to agree that the Dunning Kruger effect is a nice logical story, a shorthand if you will. I would really be careful about placing undue confidence in neat little explanations of a stupefyingly complex word, especially when it concerns yet incomprehensible structures like the brain.
