I believe that poster is using "preference" in the economic sense: https://en.wikipedia.org/wiki/Preference_(economics) https://en.wikipedia.org/wiki/Preference_(economics) "In economics, and in other social sciences, preference refers to an order by which an agent, while in search of an 'optimal choice', ranks alternatives based on their respective utility." "Individual preferences are determined by taste, need, ..., as opposed to price, availability or personal income."
