What the bell curve should have talked about

The Bell curve book argued that intelligence is mostly inherited. They when on to make a leap--therefore it is not worth while to educate the stupid since they will always be stupid. But they miss the point. In statistics, we are interested in contrasts. So the question isn't whether a stupid person can be made in to a genius, but instead whether his IQ can be increased enough to get him a better job. It turns out, this is pretty easy to do and fairly cost effective. So once again, going for the controlled experiment helps focus attention on what can be changed, and further provides proof as to whether or not the change is worth it. Go statistics!
