It is possible, then, that exposure to complex visual media has produced genuine increases in a significant form of intelligence. This hypothetical form of intelligence might be called "visual analysis." Tests such as Raven's may show the largest Flynn gains because they measure visual analysis rather directly; tests of learned content may show the smallest gains because they do not measure visual analysis at all.

Do you think this is a sensible view?

Eh, not especially. IIRC, scores have also had to be renormalized on Stanford-Binet and Weschler tests over the years. That said, I'd bet it has some effect, but I'd be much more willing to bet on less malnutrition, less beating / early head injury, and better public health allowing better development during childhood and adolescence.

That said, I'm very interested in any data that points to other causes behind the Flynn Effect, so if you have any to post don't hesitate.

I'm just trying to make sure I understand - I remember being confused about the Flynn effect and about what Katja asked above.

How does the Flynn effect affect our belief in the hypothesis of accumulation?

It just means that the intelligence gap was smaller, potentially much, much smaller, when humans first started developing a serious edge relative to apes. It's not evidence for accumulation per se, but it's evidence against us just being so much smarter from the get go, and renormalizing has it function very much like evidence for accumulation.
