People value intelligence and will apply that label to themselves even if it may not be true. It's a hard thing to measure though IQ does it reasonably well. To those who have a high IQ: what is it like? Can you pick up any book, read it, and understand the gist with minimal repetition? Can you infer solid and accurate conclusions based on a small amount of evidence? Is any subject or discipline up for grabs or do you have to have a keen interest in a particular field in order to flourish? What is something you are able to do that you know is because of your intelligence -- the proverbial 1,000 pound deadlift of the brain, if you will.
There is no point to these questions other than curiosity.
I have a reasonably high IQ, and I don't feel smart. I pick up on some things easily, other things I struggle with.
It's more that a lot of other people seem very stupid.
Pattern recognition and seeing how issues connect, I suppose. But I don't think of that as an innate consequence of intelligence, I tend to think that most people simply refuse to do it. It's not that they can't think, it's that they don't. Which is frustrating.
To be clear, the really frustrating part is realizing how stupid the supposedly "smart" members of society are. The ones who are convinced of their own infallible intellect. The midwits.
Stupidity isn't the problem. Dumb people can be smart. The problem is the veneration we as a society have for people who are utterly ill-equipped to be making any sort of meaningful decisions, whether because they're innately stupid or simply refuse to use their brains correctly.
The people who are smart enough to feel smart, but not smart enough to be smart are the true retards of society. And they are the cause of a great many of its issues.
