Thanks you for the excellent write up. I continue to suspect a multifactorial model may make more sense for mental illness than for intelligence, for much the same reason that averaging normal faces yields beauty but averaging ugly faces doesn't yield a unified kind of ugly. But either way, it will be interesting to see where the boffins ultimately land on the p factor issue.

Well done. Conscientiousness also shows a suggestive negative relationship with the Compulsive (OCD / Anorexic) group here. Surprisingly given the charts Emil provided above, OCD seems also related to lower intelligence across many studies:

Though Anorexia is still associated with higher IQ, and this is probably able to drive the overall positive association with IQ (and education):
