My disagreement was with the claim that "the Flynn Effect is in full swing". The recent small downwards trend you acknowledge is incompatible with that claim. From everything I've read on the topic, the Flynn Effect ended in the US about 20 years ago. FWIW, I administer Raven's APM tests in the course of my work.

Please speak for yourself about trolling wikipedia. I simply responded to the lazy GP's need for a citation with a google search of a relevant phrase. That said, the very article from which you quoted a sub-section has this in the header:

"Recent research suggests that the Flynn effect may have ended in at least a few developed nations"

This claim carries a citation on wp.

Your link at the bottom about educational attainment is completely irrelevant to the discussion. Intelligence and formal schooling are two different things.
