IQ numbers vary based on tests, to some degree, so "130" doesn't necessarily mean a whole lot. What I'd found is that I was in the same percentile on all tests (took 3 a few years ago) compared to tests from 30 and 20 years ago.

The raw score numbers might have changed up or down slightly, but same percentile in my case.

... IQ is supposed to be a normal distribution, ">= 130" === "3 sigma above the mean," i.e. top 0.1%.

(bearing in mind that the test is inescapably biased towards people with our background - US/UK/etc, certainly English speaking, probably university educated.)

To be fair, I wasn't university educated at 9, when I took my first tests, although I was born in the US and spoke English.

fair point indeed - the tests are highly weighted (and thus rather unsatisfactory - the skewing reduces the resolution of the test, if you like) for young people.
