Like, you know (lol, you don't) that for about 1 in 1200 people, it's always been Idiocracy?
That is (always has been, always will be) the distribution for people to be 3 standard deviations of the mean.
For them, roughly 84% of the world population is at least two standard deviations below them. Adjust the numbers so they're the average, and those 84% would fit the requirements for an intellectual disability. And the rest of those 16% are still a lot less intelligent than you, just not below that threshold.
You know why the smartest don't run shit?
Because going through existential crisis before puberty tends to make someone a nihilist. You can't even imagine what it's like to be a literal child and being smarter than everyone you meet. Because while there are people smarter than you, smart people tend to not like people, because most people are annoyingly dumb.
They're not the ones you run into out in public.
A tiny slice of that 0.1% finds something to be passionate about and focuses on that, but most never get out of the rut of "none of this shit matters, literally none of it".
Because on a long enough timeline in the grand scheme of things, literally nothing that will or could ever happen on our tiny little planet will ever matter.
The few who would actually want to rule over everyone, would be terrible fucking leaders. Especially once it gets a generation in. Because it would be its already easy for someone that smart to think normal people aren't really the same. Formalize that into a system of government?
Can you really not see where that would lead?
Your idea is just so mind-blowing dumb, that I kind of went in a rant, and I know it's not going to do.
But this is just the most ignorant idea I've ever heard.
Like, why not just fucking prioritize public education instead of this fucking shit show you dreamt up?
For fucks sake, your own plan says you shouldn't get a say in anything, yet here you are, proposing plans.
Something that is obviously even worse than what we have now. For like soooooooo many reasons I just can't list them all.
