Paranormal Adept
I did a lot of reading on IQ at one time (long ago) and came across the Flynn Effect, when you posted, it just reminded me of this and I posted it - it's pretty hard to pin down what is actually going on there, I don't think it means people are getting smarter and smarter in some absolute sense . . . IQ is not equal to intelligence I don't think and it's also not fixed. Galton posited the idea of "g" as general intelligence and claimed that it corresponded to speed of reflex, I think this was later refined with EEGs and that came up again in The Bell Curve with all it's controversies over race and IQ.

I personally think that the Flynn Effect is more so an indicator of educational familiarity, and most importantly, it's accessibility to the general public. I personally see little to no evidence whatsoever that human beings are getting more intelligent. Not at least the ones where I am from.
