Wow! .9 correlation at iq>160?

That means people at extremely high IQs, the brain has a hard time balancing high functioning in all general areas, and actually starts depleting some parts of the cortex. The brain is essentially at full capacity and must balance this by having weak areas resulting in SLDs, ASP, and ADHD, dyslexia etc.

So around 140-150 iq, less 2E occurrences because the brain isn't at full capacity and can balance effectively? So therefore, the more average iq a person has the more well rounded they can essentially be, but not necessarily especially great at one thing?
