Not really an answer to your question, just wanted to say intelligence isn't a one-dimensional thing. You can practically be a master on any one field but lack basic abilities in accomplishing what other people do every day. Or the other way around, you're not particularly good at one thing that's commonly attributed to intelligence, like chess or maths, but be highly intelligent or skilled in other things. And for me that includes social intelligence, being able to remember a lot of stuff, being handy or having a grasp for music, or anything. I think I'm alright in various things. But I regularly observe people being very good at something. Like scientists and I can barely read what the math even does. Or the lady at the bakery who remembers things about the personal lives of like >200 grandmas and which kind of bread they buy every week. In turn, I know like a 200 facts about Linux networking. But I couldn't do what she does, even if I tried.
