However, he omits several important matters, one of which is the increasing use of tests like these with school children. There will be practice effects even if the tests are not identical. Think of how much better HS students perform [on average] when they take the SAT a second time. And if SATs are surrogates for IQ tests, as the reviewer argues: well, there you go. Looking for social- cultural-technological-diet factors that produce the outcome is, for Flynn, a cheap shot. Surely something out there is doing the trick; let's make something up.
