A related point, the heritable effects might not need to be direct. For instance, suppose someone is genetically predisposed to be small and weak. In that case, it seems like physically dangerous things like big strong aggressive people or wild activities would be more dangerous for them, and they would therefore have more reason to fear them. We might expect the within-lifetime RL to therefore lead to them being more neurotic/emotional about such things.
Nice.
