What is the folk concept of art? Does it track any of the major definitions of art philosophers have proposed? In two preregistered experiments (N = 888) focusing on two types of artworks (paintings and musical works), we manipulate three potential features of artworks: intentional creation, the possession of aesthetic value, and institutional recognition. This allows us to investigate whether the folk concept of art fits an essentialist definition drawing on one or more of the manipulated factors or whether it might be a disjunctive or cluster concept. The results suggest that none of the three manipulated properties alone suffices for an object to be considered art. The folk concept of art might thus well be a cluster concept instead of an essentialist concept.
