Really? That wasn’t my understanding at all. I had thought this was highly reproducible, life time stable, as strong a result as exists in psychology. I can imagine it being unpopular. As so much of my own personal success and “identity” is wrapped up in iq, I have been reluctant to accept the concept of a fixed general intelligence factor as being behind it. It’s a bit like being attractive. “Oh you got all that because you are pretty”. Well, I’m pretty and I worked hard. However, I can’t argue that I had any influence over being born with a higher than average iq. Still, IQ, like most things, is far more complex and multi-faceted as you dig in to the detail.
