The world supports a multi-million dollar industry of intelligence and ability research, but it devotes virtually nothing to determine why this intelligence is squandered by engaging in amazing, breathtaking acts of stupidity.

I've taught statistics, math courses and what I've found is that often if you teach them algebraically the formulas, you'll have one group of kids doing well.

The essence of intelligence would seem to be in knowing when to think and act quickly, and knowing when to think and act slowly.

Current intelligence-testing practices require examinees to answer but not to pose questions. In requiring only the answering of questions, these tests are missing a vital half of intelligence- the asking of questions.

Well, first of all, we did lots of studies where we show practical intelligence doesn't correlate with G. We have probably two dozen studies that practical intelligence better predicts job success than IQ.

And so, you can do hundreds and hundreds of studies showing a general factor and just so long as you restrict your populations, your testing materials and the kinds of situations you look at, you can keep finding the same wrong thing again and again.
