I emotionally/connotationally associate the condition of not thinking clearly with poverty. A person can be born in unfavorable conditions, in which case it might be almost impossible to get into a better situation without substantial help, or it might take a lot of luck, or significant ability.

Since there is already a well-absorbed set of emotional connotations with the condition of povery (low-status but with lean to status-agnostic; burden for others not in this condition; unfair, deserving of compassion and help; theoretical possibility of full recovery) that seems to match what one would wish to associate with people not thinking clearly, you could just transfer these intuitions by associating the categories in your thinking.

We also need a productive charity, to make use of comparative advantage.
