THOMAS SOWELL: The Brainy Bunch
There is usually only a limited amount of damage that can be done by dull or stupid people. For creating a truly monumental disaster, you need people with high IQs.
Such people have been told all their lives how brilliant they are, until finally they feel forced to admit it, with all due modesty. But they not only tend to over-estimate their own brilliance, more fundamentally they tend to over-estimate how important brilliance itself is when dealing with real world problems.
