I’m thinking about this in a broad sense—is someone with a higher IQ more likely to develop any kind of mental illness? Or perhaps looking at specific cases, like how OCD seems to hit people with higher intelligence quite often. If anyone knows, I'd love to hear it.
And if you have any citations or studies to back it up, please share. 👋
Well, I'll try to answer based on what I've gathered from spending quite a bit of time studying psychology.
The window for personality development—specifically those first four years of life—is basically the same period that determines IQ. So, I don't think the connection is just some media myth; it's actually quite literal. If personality development goes off the rails in an unconventional way during those first four years, there's a much higher chance it will impact abstract reasoning, which is essentially what intelligence is.
Most people struggling with mental illness were somehow affected or shaped during that initial four-year period. A significant percentage of them—including those prone to depression—might have been forced into developing abstract reasoning capabilities because they weren't living carefree lives during those formative years, which resulted in mental health issues.
It seems pretty logical to me. Besides, I suppose no one can argue against statistics showing that people with mental illnesses don't necessarily have significantly higher IQs.
As for emotional instability, that's a separate issue. That falls under the umbrella of mental illness rather than intelligence... though the link between the two lies right back in that developmental stage.
Here is one more piece of data that supports my theory: I read somewhere that there isn't a specific profile predisposed to PTSD, and consequently, those individuals don't have a higher average IQ... mainly because PTSD can happen at any point in a person's life, not just during those first four years.
I hope I haven't made my thoughts too tangled and confusing. 😂
