Do you have any more info on the IQ graph? I was under the (possibly mistaken) impression that IQ was a relative measurement and that the average IQ would always be constant (100 points or something).
It is, but if you track the average IQ over time using a comparative metric IQs now are higher by about 3 points per decade (one standard deviation in 50 years). It’s known as the Flynn Effect.

Ah, so the IQ values in the graph are a sort of reverse “adjusted for inflation”.
