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.

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.

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

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.

If you're not adapting to the very rapidly changing environment, if you can't think creatively, you lose big in this society because there are very few jobs for you left.

So, for example, if a child is labeled as having a learning disability, it has very concrete consequences for the kinds of services and potentially accommodations that child will get.

There is no recipe to be a great teacher, that's what is unique about them.
