> Not my claim. > That won't work. We know from science that the IQ gap appears before school age so it's not caused by school. I'm not going to waste my time on this if you're not going to stand by your claims. The IQ gap that appears and is measured before school age can be reduced by external intervention. Therefore, if the tests are accurate, then something is happening to those kids as they age to make their skills regress. If the early tests are not accurate, then it stands to reason that adult tests could suffer from the same problems and should be similarly distrusted. Either way, your claim that IQ tests prove that the sole cause of gaps must be introduced before children reach school age is unsubstantiated.
