Allocentrism is closely related to collectivism; it is the psychological manifestation of collectivism.[10] Scholars have discussed collectivism since at least the 1930s.[11] Collectivism has been used to describe cultural level tendencies and has been described as a "broad cultural syndrome.".[12] It was not until much later (1985) that Triandis, Leung, Villareal, and Clack proposed that the term allocentrism be used to describe collectivistic tendencies on the individual level.[13] They proposed this because of the confusion that arises when talking about cultural level collectivism versus individual level collectivism. Allocentrism, therefore, has been used since by some scholars to describe personal collectivism, "the individual level analog of cultural collectivism," [14] as a very broad cultural trait.[15]
