IQ tests are age adjusted assessments on how much you’ve learned for your age. They do reflect education and mental development through education.
You are correct, they don’t test recitation of facts, but if you studied math puzzles, your brain became better at math puzzles. IQ tests will detect that.
I suspect the strong cultural and geographic differences between IQ scores has more to do with familial encouragement of study and innate resistance to impulsive behavior that pulls people away from study. Just one hour per day of study is a thousand hours every three years. That’s six thousand hours of brain development by the time we turn 18 and yes, babies can study the world around them or they can just eat and suck their thumbs.
