In this post I described the information I use to reach the conclusion. I’m afraid I don’t know rationality good enough to make it more clear (or investigate if my belief is rational myself). So one of my later posts will likely be about some of my specific ideas.
About the g-factor. I can imagine a weak person who has an extremely strong leg. I would think that such a person isn’t “generally” strong. Because I already have an idea how a generally strong (and above average) person looks like.
But with IQ tests, I’m not starting from believing that they measure general intelligence. Maybe I don’t even have a good idea how a generally intelligent (and above average) person should look like. So the fact that there are in fact multiple different ways to break the correlation makes me doubt IQ more.
