Yeah. The raise is not a simple shift of the entire curve.

Though, this resonates with another topic: there's a lot of people today living in conditions vastly inferior to Americans or Europeans of 1910, mostly in Africa, scoring about the same on the IQ tests as western folks from the 1910 supposedly did. I see a plenty of people both accept the Flynn effect (whenever thinking about their superiority to people of the past) and think that said IQ gap is caused by inherently lower abilities (whenever thinking about their superiority to people of other races).
