Flynn effect gains in IQ scores are hollow. They, by and large, do not correspond to real gains in what people understand as intelligence. This is because they do not act on g. It is more useful to think of them as measurement error, as if yardsticks we used to measure length we’re getting shorter generation by generation: we’d observe then things getting apparently longer, but this elongation effect wouldn’t be real. We have known all of this for more than 2 decades now. This thread is full of people saying completely inane things about psychometric and intelligence research. I don’t blame them: the field itself is very technical, and at the same time there are plenty of people who don’t like its findings, and then misrepresent them (often deliberately) to the general public. For one thing, if you want to talk about anything related to IQ tests, but have no idea what the g factor is, please note that you are missing the absolute basics of the field, and you’ll be completely hopelessly confused by some easy to explain and understand facts.
