Really?! So he's saying that it is highly unlikely that children will be smarter than their parents?
I wonder if he's heard of the Flynn Effect.
IQ is measured relative to one's cohort. If people born in 2000 have higher raw scores on an IQ test administered in 2010 than people born in 1970 did on the same test in 1980, the IQ test will be re-normed to maintain a constant average IQ of 100. The Flynn effect is compatible with mean reversion of IQ.
Yes... but doesn't that mean that the tests have to be re-normed because the 2010 testers scored higher on the same test than the 1980 testers?
In other words, the later generation is testing higher on the older test? As in, if the test was left alone, the later generation would test as having higher IQ's? (I think the average increase is 7 points per generation).
Am I not understanding it correctly? Please correct me if I'm on the wrong track.
(Mind you, I'm guessing this is also a reflection of environment, which is not what this thread is about...sorry)
