In other words, if a teacher only teaches in one way, then they conclude that the kids who can't learn well that way don't have the ability, when, in fact, it may be that the way the teacher's teaching is not a particularly good match to the way those kids learn.

But what many psychologists have done, probably because they did well on a test themselves and everyone wants high self esteem, is to create this little box and then do their research inside it.

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.

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.

And in order to succeed in later life, you need creative skills because look at how fast the world is changing.

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 had planned to be a psychology major, but I bombed introductory psychology.
