Stupid is as Stupid Does

Here's something everyone knows about (or should): Stupid people don't know they're stupid.

In an article entitled "Unskilled and Unaware of It: How Difficulties in Recognizing One's Own Incompetence Lead to Inflated Self-Assessments" by Justin Kruger and David Dunning, it was posited that:


...when people are incompetent in the strategies they adopt to achieve success and satisfaction, they suffer a dual burden: Not only do they reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the ability to realize it.


The article's a bit heavy on the psychological terms but all in all, it's reassuring to know that the person arguing with you on some point or another has no idea what he/ she is talking about.

Hell, I could have told them that meself... er, speaking from experience in interacting with the said kind of people.
