Generalities are fine (when accurate) for making general decisions, but less helpful for making decisions on individual cases. One may assert, and it may be true, that "most people arrested for a crime are found guilty" -- but that is no reason simply to stop having trials and assume all persons arrested are guilty. When a generalization has many exceptions, it is proportionately less useful as a tool for discernment and action. As the old saw has it, "It is always wrong to make sweeping generalizations."
