| I'm repeating what people with PhDs in psychology and psychopedagogy with specialities in measuring knowledge, intelligence and ability, which are currently implicated in ongoing research in the field have told me, almost verbatim. There are currently a lot of unknowns as far as IQ. We have yet to accurately measure the cultural impact of IQ tests, in fact, we have yet to come up with a solid methodology for that, as all IQ tests are cultural artifacts. We have yet to properly measure the fetal and epigenetic components of IQ, with differing impacts found that are still not totally accounted from. We have yet to manage to completely square away at the Flynn effect, which is an incredibly large effect on IQ that may be fully cultural according to some psychologists, or based on non-cultural environment, as far as I'm aware or have been told this is still not fully explained. At the same time, changes in relative IQ scores between groups are difficult to account for if IQ is as heritable as it seems to be, There are a LOT of unknowns in IQ. It is far from "as well as understood as science can". We don't even know all that we don't know. This isn't the Gell-Mann effect in action. This is someone trying to pass off a controversial opinion in a field (perhaps not amongst people whose job is to work on the tests for obvious reasons) as the established truth, and in doing so ignoring a body of research, which is far from unusual especially in these fields. At the very least the fact that I've heard one thing from multiple subject matter experts and something else from them shows that there is significantly more doubt and uncertainty as claimed in the original message. |
