In a mordant lesson for Ted-Ed written by educator David Dunning and animated by Russell Etheridge, Allen Lasseter, Ezequiel Matteo, Andrew Embury and Wednesday Studio, narrator Addison Anderson explains the premise behind the Dunning–Kruger effect.

Psychological research suggests that we’re not very good at evaluating ourselves accurately in fact we frequently overestimate our own abilities…on average people tend to rate themselves better than most in disciplines ranging from health leadership skills ethics and beyond. What’s particularly interesting is that those with the least ability are often the most likely to overrate their skills to the greatest extent.
