Is there evidence that having an ultra high IQ is a hindrance? As far as I know, having a very high IQ is advantageous. IQ relates with job performance and income. Having a high IQ is quite the opposite of a hindrance. I think that what normally happens is this: - and this is not easy to deal with. The above-average IQ person must have parents, other relatives, teachers and others who will not hold it against them to be above-average and who will not otherwise sabotage them, but instead provide with good life skills. Without that supportive social network, I think the above-average IQ person is likely going to have many problems in life.[/QUOTE] I'm sure this happens, and I've heard of it happening, but is it statistically significant?
