Remember the “Flynn Effect”? It turns out that even James Flynn now agrees with the new mainstream consensus that genotypic intelligence is declining over time. The Flynn Effect was merely capturing enviromental improvements that temporarily boosted average IQ for a few decades.
Author Richard Lynn is most responsible for noticing this more fundamental decline. So I propose we name this the “Lynn Effect” – the fact that world IQ is now declining over time — and the genetic contribution to intelligence appears to have been declining for over 100 years now.
