If IQ is increasing over time, why are paranormal & conspiracy beliefs not going down (IQ cor. ≈- .30)? Role of need for cognition/analytical style? http://www.sciencedirect.com/science/article/pii/S0191886917306323 …
FLynn effect is not a real increase in general intelligence, so the correlates don't change. Similarly, no sudden spark of geniuses appearing despite 30 IQ gains since 1900. A real increase of 2 sd IQ would have huge and very noticeable effects that we are simply not seeing.

Think Murray says in TBC that the Flynn effect is due mostly to the lower tail of the distribution shifting to the right, rather than the whole distribution moving. Moving from IQ of 85 to 90 isn't going to dispel religious beliefs necessarily

Not well supported by later evidence. Read some of the meta-analyses.

The Flynn effect shows that IQ tests are of limited use in measuring IQ across disparate environments. Comparing the 6th form at Eton to each other, fine. Comparing them to Inner city Bengalis, useless.

Does not follow. FE is about temporal shifts, not geographical.

Same thing. Change of environment, not genes.
