Dormammu, I've come to bargain.

I'd say in terms of advice, it would be that intelligence is a lie, I think. The fact that the I.Q. system as a whole caters to discrepancies and strengths that heavily rely on whether or not you're neurodivergent. Processing speed, "age-appropriate" behavior, and verbal skills all being issues in that area that will absolutely TANK your score. Plus there's the fact that it was written with so much cultural bias that they had to completely rewrite it multiple times for non-western audiences. It's a bullshit system. People will try to separate you into "creative" or "smart". "Book-smart" vs. "street-smart". They'll say you're not as quick as someone else, and that makes you less intelligent.

The thing is, information and skills can be learned. Neither of these, whether you have them in spades or not, have anything to do with how intelligent you are at all. Creativity is intelligence. Social understanding is intelligence. Charisma is intelligence. All of these things aren't about how fast you can do a math problem, it's about the shit in your brain. How well you pick things up, what sticks, how you apply it, the connections you make. You can't put a score on something so vastly different for each person.

It's like taking a speedboat, a tugboat, a sailboat, and a warship and ranking them all on how fast they are to determine the best one. Objectively they can all do that at varying levels, sure, but there's no one best boat out of those because it can go the fastest. They're just all designed for different things. People are like that too. Putting a number on how well your brain works according to a set of parameters isn't going to determine shit other than how well you fit into those parameters. Intelligence is a lie. You can't just measure it like that. Look around you- that guy you went top high school with who almost failed out of graduating, but could figure out just what play to make to win the game? He was smart. The kid who was in all advanced classes but never talked to a single person? Smart, too. The one who never knew what was going on in class, but could fit in with any clique and had a great relationship with everyone? Smart. They're all smart. It just presents differently.

Stupid people exist, but they're much harder to find than you might think. Usually it's just ignorance or a lack of resources. Like I said, most of those things we consider smart things? They have to be learned, and not everyone has the opportunity to do that. And some people... they just don't care enough to. So yeah, intelligence is a lie. IQ is a lie. Putting a number or a quantifier or a comparative value on anyone's brain power is a lie. You just can't do it and expect to get something useful out of it, least of all an overall quantifier for how "good" someone's brain is at doing brain things.
