It is obviously just one person's blog post, but I did find it interesting and compelling. However, I must admit that some of the areas of discussion surpass my level of knowledge of statistics and psychometrics.
I am just curious what your opinions are since you seem much more versed in this topic than I am.
- llamaimperative 2y agoTo be clear I’m nowhere close to an expert. But my reaction to that blog post is that I’m not quite sure what it’s rebutting? It seems to argue (successfully, I guess) that g isn’t some singular source of intellect that’s powering all other dimensions of intellect. I am not sure if other people believe this to be the case, but I certainly don’t, as that seems contrary to the structure of the brain itself. There is no “smartness” lobe that’s supporting the “smartness” of all the other things the brain is doing and smart people have a bigger/better smartness lobe than dumb people. That’s just not what the brain looks like. What this blog post does say, which I believe to be true, is that intelligence on one dimension is highly correlated with intelligence on other dimensions. Not because they’re necessarily all driven by the “same source,” which seems like an implementation detail with, AFAICT, pretty much zero bearing on anything of practical concern?
