Have you ever noticed how incompetent people are often incredibly confident? Meanwhile, highly-skilled folks underestimate their ability to perform. That's called the Dunning-Kruger Effect named for Justin Kruger and David Dunning of Cornell University who published their study of the cognitive bias in a 1999 scientific paper. ABC Radio National's The Science Show recently explored the Dunning-Kruger Effect. According to the scientists, "Overestimation occurs, in part, because people who are unskilled in these domains suffer a dual burden: Not only do these people reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the metacognitive ability to realize it." ABC Radio National's The Science Show recently explored the Dunning-Kruger Effect:
Pittsburgh, Pennsylvania, 1995. A local man, McArthur Wheeler, walks into two banks in the middle of the day and robs them both at gunpoint. Making away with the cash, he is arrested later that evening. Back at the station police sit him down and show him footage from the banks' security cameras. Wheeler can't believe it, the cameras had somehow seen through his disguise. He was seen mumbling to himself, 'But I wore the juice.' His was no ordinary disguise; no balaclava, mask or elaborate makeup, just lemon juice, liberally applied to the face. He was certain that the squirt of citrus would render him invisible to security cameras.

Charles Darwin once said, 'Ignorance more frequently begets confidence than knowledge,' and Dunning and Kruger seem to have proven this point. In light of this, it suddenly becomes clear why public debate can be so excruciating. Debates on climate change, the age of the Earth or intelligent design are perfect real-life examples of the Dunning-Kruger effect. It beautifully explains the utter confidence of those who, with no expertise, remain stubborn in their views regardless of overwhelming evidence. It makes you want to shake them by the collar and scream about how stupid they are. But evidence shows that's not the best strategy.
