We are living in an age of unprecedented wealth, with millions entering the middle class every year. Homo sapiens live longer lifespans than ever before, with better nutrition, and better medicine than ever in our history. This is also the most peaceful time in our history, with record lows in crime and wars. The developing world is surging in wealth and in the west we have more opportunity and access to information than ever.

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".
