Oh my mistake, ~50% means 50% +/- a factor of two. say 25-75. I have no idea, I've not studied the inheritance of intelligence. Murray and his co-author did that.
Well that's the whole enchilada, who you are is part genetic. I can't train my plumber to be Einstein, mind you we need a lot more plumber's than E's. So I'm not disparaging plumbers at all.

Listen, I have no idea what you are on about. Go listen to Sam and Charles, they are both very rational men. If you don't find it so... well I don't know what. I'd be surprised.
