Professors Justin Kruger and David Dunning provide supporting research. Their findings are categorically called the Dunning-Kruger Effect (DKE). In my earlier post about lying, we saw liars using confidence to encourage lies to take hold. Since confidence is a feeling that taps into our security needs, it naturally attracts us. Thus, a mother’s embrace is to a child what confidence is to an adult.
It seems natural though that those who are most competent should have the most confidence; but why does DKE claim the opposite? The incompetent don’t really know what they don’t know.
Imagine two generals. One sends his scouts out and finds no enemy forces. Another does the same and finds a force twice his size. Which general is going to feel more confident about his situation, the one with no enemy around or the one with? However, we then find out that the first general only sent his scouts out five miles while the second fifty miles. Which now? The answer doesn’t change because the first general didn’t know his scouts should have gone out fifty miles.
However, measuring competency isn’t as easy as measuring how far scouts ventured. The potential problems that concern the competent are staging far beyond a horizon the incompetent can’t see or don’t know exists. Thus, ignorance is not only blissful but confident.
Want proof? Next time you’re before a group of CEO’s ask how many of them believe their earnings growth over the last year is in the lower half of the group? You’ll get a number far less than 50% . . . maybe even 25%.
