Dunning-Kruger

[Spencer Campbell]

Who said the graph of self-assessment (y-axis) versus actual mastery (x-axis) looked like this?

I gave the Dunning-Kruger effect as "regardless of actual skill, everyone believes themselves to be slightly above-average", and that's exactly what every graph I can find says. Greater skill consistently increases your self-assessment, but not very much. It looks like a very gentle upward slope: if you should assess yourself as 10th-percentile, you'll assess yourself as 60th. If you should assess yourself as 90th-percentile, you'll assess yourself as 70th. Self-assessment is most accurate somewhere between the 60th and 80th percentiles of actual ability; accuracy decreases as you get further from that range.

Anyone else want to google it? Maybe I'm only looking at lousy science.
