Reason Hell: The Dunning Kruger effect

A short Reason Hell this week. The Dunning-Kruger effect has had a lot of publicity bu one of the things I really like about it is that one of the papers by Justin Kruger and David Dunning is just so readable. It also has one of the best anecdotes ever used in a serious and influential paper:

In 1995, McArthur Wheeler walked into two Pittsburgh banks and robbed them in broad daylight, with no visible attempt at disguise. He was arrested later that night, less than an hour after videotapes of him taken from surveillance cameras were broadcast on the 11 o-clock news. When police later showed him the surveillance tapes, Mr. Wheeler stared in incredulity. “But I wore the juice,” he mumbled. Apparently, Mr. Wheller was under the impression that rubbing one’s face with lemon juice rendered it invisible to videotape cameras
