I was considered gifted as a young kid, but everyone else caught up and I didn't keep up with them, so I've never tested that way since. (I blame it on being hyperlexic and able to read at an age where most kids can't, when I was tested.) I don't know what intelligence is, but I lack the ability to be abstract for very long, if that's what people mean by it. I can't hold a lot of ideas in my head at once. And I'm certainly socially inept. But my autism-related problems (which go way beyond social issues, into a lot of self-care issues and difficulty understanding the world) are such that I'm not sure any amount of what most people call intelligence, would help me do much better than I do now.
