I think it means something on average. I'm guessing most physicists etc have higher than average IQ.

IIRC there's also a general correlation between higher IQ and success in terms of school/career.

I've never taken a professional IQ test, as I'm pretty sure you have to pay for that. But I've taken online ones. Based on those questions, I believe it's something that you can improve on if you do a lot of math, logic puzzles, programming etc. I don't understand the idea that IQ is static if it's based on these logic puzzle type questions.
