Having taken the WWI era Army IQ test that was the basis for some of this, I can verify that a significant amount of it seemed to be education based (questions regarding brands of motor engines and whatnot probably posed issues for immigrants who'd rarely seen and never driven cars, for example).

Given that there is significant existing variation in human intelligence, it's curious that we are not all much smarter than we actually are. Besides the well-known costs of higher intelligence (e.g., more energy use, bigger heads causing more difficult births), it seems that being smart can be a
