I'm impressed that people with IQs of 150 are 4X more likely to suicide. That's sobering. I'd like to know how this has trended over the past century. And if it applies to other forms of talent than just IQ. I also like the OP's division between giftedness as potential vs as achievement. I've know far more gifted folks who belonged to the first group more than the second. That dichotomy nicely captures the importance of drive to the full expression of any natural gift. Far fewer gifteds are comparably hard chargers, in my experience. It's likely that before today's "age of quantitation", fewer gifteds were as aware of the gap between their talent and its lack of expression. Or maybe their attention was focused elsewhere -- on family, duty, or other life endeavors that were unaffected by the gift.
