Although there has been progress in the definition, antecedents, and consequences of individualism and collectivism, there are some fundamental issues that need to be resolved. This study examined two such issues: the dimensionality of individualism and collectivism, and the relationship of these constructs to authoritarianism. Thirty‐eight American undergraduates judged the similarity among 15 concepts that have previously been shown to be reflective of elements of individualism, collectivism, and authoritarianism. Multidimensional scaling revealed two dimensions: individualism versus authoritarianism and active collectivism versus withdrawal from group involvement. Unlike the conception by Hofstede (1980) that individualism and collectivism are opposites, these results strongly suggest they are orthogonal. Furthermore, authoritarianism was construed as the opposite of individualism. Implications of these findings for future research are discussed.
