Status symbols also indicate the cultural values of a society or a subculture. For example, in a commercial society, having money or wealth and things that can be bought by wealth, such as cars, houses, or fine clothing, are considered status symbols. Where warriors are respected, a scar can represent honor or courage. Among intellectuals being able to think in an intelligent and educated way is an important status symbol regardless of material possessions. In academic circles, a long list of publications and a securely tenured position at a prestigious university or research institute are a mark of high status. It has been speculated that the earliest foods to be domesticated were luxury feast foods used to cement one's place as a "rich person".
