When my microeconomics/mathematical economics professor at Johns Hopkins, M. Ali Khan, queried us about something in the course of his classroom lecture, I said, “De gustibus non est disputandum“, referring to a famous 1977 essay by George Stigler and Gary Becker (two Nobel Prize winners in economics) — https://www.jstor.org/stable/1807222 — that argues consumer preferences are fixed, stable, and largely identical across all people, which made him smile approvingly.
De gustibus non est disputandum is a Latin maxim that means “in matters of taste, there can be no disputes”.
Meaning and Usage
Core idea: Personal preferences (like art, food, or style) are subjective, so arguing about them is pointless.
Literal translation: “About tastes, it is not to be disputed”.
English equivalent: “There is no accounting for taste”.
