> Schizos (correlated with IQ)

Schizophrenia may (or may not) correlate on the phenotype level, but genetically, they are inverses. Genetic risk for schizophrenia lowers IQ in GCTAs, genetic correlation, and family studies. If you select for intelligence, you will get less schizophrenia, and if you select against schizophrenia, you will get more intelligence.

Good catch. I'm not sure where I got this idea that schizophrenia is more likely to develop in high-IQ individuals, but that's what I thought.
