Actually it was well known prior to James' popularisation of the effect. Until his work, most of us had simply discounted it as an artifact of something unrelated to underlying intelligence. It may turn out to be such.

Not the average person by any means, but yes, since the war increases of up to a standard deviation have been observed on some, but not all, tests.
Defining genius as scores >140, 9.2% of Netherlanders would score in this range using 1945 norms.

because anyone who has talked to Art for more than 10 minutes recognises that he is a real scientist: insightful and precise with an honest curiosity. his latest book on the g factor is virtually an encyclopedia. His previous works are in daily use when most texts are propping up equipment in the back of the lab.

The "matter" is simply one of fact: scores have increased.
The real question is why? This is in no-way settled.
Flynn argues that we cannot be more intelligent (he sees no signs of it)
and that therefore the tests are to be viewed as rather distant
indicators of general ability.
There are a range of other interpretations, most simply, there are two
main alternatives.
Scholars argue that this could be due to
either a decrease in the the number of people with nutritional
I have a set of web pages on IQ that some of you may find useful in navigating these issues for yourselves.
