This makes good sense in my experience. I was struggling socially and academically in college so they proctored an IQ test to look for things like ADHD etc. I scored in the 98th percentile for verbal comprehension. Only 2 years later did I have my first psychosis and was diagnosed with Schizoaffective. Luckily after a few rough years I'm doing well on the lowest dose of an antipsychotic and can function in society again. But there are definitely cases of highly creative or people with strong language skills that the expression goes too far like this post suggests.
