Just something I have anecdotally noticed occuring with more frequency. Several creators I follow have spoken about being diagnosed with ADHD in recent years, and their experiences with medication like adderall. When I was a kid, ADHD was something only kids had, and was famously overdiagnosed in America as an excuse to get a ton of kids on pills.
Is this just a more recent extension of that? Is it just as simple as big pharma looking for more addicts? I have definitely noticed that my own attention span has been eroded by the 24 hour news cycle and too much screen time, but I'd never think to go to the doctor about it.
Depends on the type. "Genius" is a broad range and can refer to individual skills, which does lend itself to weirder behavior. For example, math geniuses can overspecialize and start looking at everything as math, or ignoring everything they can't solve with math. That is how you get "intelligent" scientists buying into climate change solutions, because they trust the numbers and don't see the manipulation going on behind the numbers.
