If you don't like the hair color analogy, height would also work, and I know we don't know 100% of genes there.

height and hair color also have the virtues of being easy to measure and unambiguously defined whereas "intelligence" is the opposite

hmm, no, the Vox article specifically says that there's strong academic consensus about what intelligence is & how to measure

and SABR people would laugh you out of the room if you posited "h" a factor that could be expressed linearly that determined hitting ability

You think no statistic is even *correlated* with underlying ability?

That if we know one guy has highest batting average in league, and other guy has lowest, we have literally no clue who's better?

oh sure there are correlations but positing a single underlying factor isn't useful the system (batter vs pitcher) is too complex
