There's definitely a correlation between IQ and rational/emotional intelligence development (what the Foundation for @FCriticalThink covers nearly in total in their CT Development Stage Theory stages, what I would call a capacity and potential for efficiency vs quality and consistency). However, at a certain point, the higher the IQ, the less "normal" the person becomes, and much of that correlation can easily go out the window due to trauma, especially in childhood. US Mensa's special interest group (SIG), "Firehouse," is full of people who join because they feel like total outcasts, wanted to find similar minds, but still end up very dependent on cognitive self-defense mechanisms which results in massive amounts of pseudo-intellectualism as their main way of self-validating via intellect-signalling... and making them effectively "dumber" and more prone to mental illness inspired violence.
