Knowledge of Population Heterogeneity

Paternalists need to have knowledge of this, which they usually do not have in specific circumstances. This is the reason that scientific knowledge can't substitute for local knowledge. Even if a paternalist planter happens to know that a bias exists on a population level and that it has a certain average extent or strength across that population, what ostensibly needs correction is their individual level of bias. Unless a policy can be designed somehowon individual level, everybody gets their own personal correction from the state,. then the policy has to be based on the average, or perhaps a judgment, of the entire distribution of the population. But the popula will necessarily have a one size fitzall character.
