How about “solving puzzles makes you smarter, therefore IQ measures something real”?
There no good research that suggests that solving puzzles makes you significantly smarter in the same way that lifting weights makes you significantly smarter.
Isn’t there an “obvious” causal relationship between brain mass and intelligence?
The fact that women generally have smaller brains than men doesn’t mean that they are generally less intelligent in the same way that the fact that women generally have less muscle means that they have less strength.
