> I don't see any investigation of whether IQ can be altered through nurture (which I think it can). Invert, always invert. Looking at 'nurture' as a positive action may not cover all the cases of increased IQ. Generally, yes, I think that investing more time into others is going to increase the IQ score (for many reasons). I think this is a great thing we all should invest in. However, there is the edge case where a lack of nurture will also increase it. The adversity is overcome and the person becomes more 'IQ-y' as a result. Ramanujan come to mind as a perfect example of a person overcoming large adversity to achieve great status. These edge cases aren't particularly repeatable, of course, but they are instructive. These people are the very end of the 'long tail' of these statistical constructs and give great insight into what it takes besides pure luck. https://en.wikipedia.org/wiki/Srinivasa_Ramanujan#Early_life https://en.wikipedia.org/wiki/Srinivasa_Ramanujan#Early_life
