That is the only way I’ve found to reconcile the competing observations on the subject. This is an extremely important subject, and it is frankly astonishing that no one approaches the subject with any nuance at all. Broadly, here are the two camps:
1. Unusually high IQ is somehow good for normal functioning: Terman, Cooijmans, et al.
2. Unusually high IQ is somehow bad for normal functioning: Prometheus society, Pumpkin Person, various whackos like myself, et al.
I believe that the dysfunction arises from non-IQ personality factors that happen to be heavily concentrated in the 150-160 IQ range (example theory), whereas IQ itself is an unmitigated good that actually makes these people less dysfunctional than they would be otherwise.
There are two different personality dysfunctions which predominate: too much associative horizon, and too much psychoticism. These appear very similar, so I’ve disambiguated them here. Associative horizon is primarily concerned with verbal IQ and executive function, and may be due to low latent inhibition (driven primarily by the reticular activating system). I believe it may be tested by playing associative word games, or by testing the number and complexity of possible explanations that can be drawn from the same evidence given to a jury. I believe psychoticism can be measured by visual perception tasks like playing “Where’s Waldo?” because I believe it is due to a disproportionate ratio favoring gray matter over white matter.
In edenic terms, I think the 150-160 crowd is more likely to be the TTs, who are dysfunctional due to personality problems, and anything higher usually requires a melon back with high parietofrontal integration (i.e. rate of “discernment” as I’ve described it).
In Aeoliworld terms, this could be explained by the strange interaction between white matter and gray matter. Without a functioning base of white matter, you simply can’t score above 130 on an IQ test. It doesn’t really matter how much gray matter you have because even if you can spot patterns, you can’t use reason to solve problems with them. But if you have a functional, rational base of white matter, then the primary determinant of your IQ is your ability to spot patterns.
I don’t even know why I write this stuff sometimes, I’m just repeating myself over and over.
