I ran into an interesting comment on the net the other day.. "for some, it is hard to determine what productive and ethical use society can make of genetic knowledge that certain individuals are predisposed to higher than average intelligence"

Perhaps others can think of some productive and ethical uses. Any suggestions?

Some people may already have a certain amount of such knowledge. For example, my high school geometry teacher thought I would probably do well - he had some strange rationale based on remembering how my mother had done in his class. I did do well, but maybe he was just a lucky guesser.
