I'll accept "leveled off" regarding certain countries, having read Flynn's work, and I'll accept "starting to reverse" if you are only talking about crystallized intelligence, for the same reason, but do you have any current citations to a disfavorable trend anywhere in fluid intelligence?

I'm looking for a copy of the paper that doesn't require access to a university archive. Every link so far goes to the same source. the name of the paper if you want to look for it is

A long-term rise and recent decline in intelligence test performance: The Flynn Effect in revers

Also, from mynameishere's Wikipedia reference:

"The end of the Flynn effect?: A study of secular trends in mean intelligence test scores of Norwegian conscripts during half a century"

http://dx.doi.org/10.1016%2Fj.intell.2004.06.004

After all, this makes sense. Flynn effect seems to be working mostly by reducing "bad stuff" going on that would make you dumber than your potential (most of the gains are concentrated in the lower half of the distribution and negligible in the top half).

Once everybody's environment is more or less ok, there is no magic that will start to produce geniuses from normal people.

There was a comment on iSteve, where someone said that perhaps whites were not intrinsically smarter than the global average (of about 90) but, that they've had a headstart of a century of Flynn Effect.

this is an actual possibility, watching the flynn effect in devloping vs industrialized nations is what led to the idea (AFAIK) there's not enough data to be able to draw any conclusions, partly due to the stigma of intelligence research.
