I think one should find that IQ is more highly correlated with myopia than academic achievement
More correlated than academic achievement is correlated with IQ, or with myopia?
Your comment is a very good point. But IQ may be more-closely correlated with academic achievement than academic achievement is with reading books; so this comparison might not help. (And you want to talk about the variance in X accounted for by Y but not by Z, rather than place a bet on whether Y or Z has a higher correlation with X.)
Yes, of course. But remember that in science we are not in the business of “accepting” one thing of another. That is the domain of religion and politics. The only thing that matters is finding good hypotheses and testing them.
