In various political, academic and educational contexts, "equal rights" of children and adults are being demanded. The main part of this paper examines a voluminous selection of review literature on parenting, asking which consequences can be anticipated, according to the current empirical parenting literature, if parents follow an ideal of equal rights relationships in dealing with their children. Equal rights relationships are defined as providing self-determination, codetermination, equivalence of needs and an advance of trust. The utilized review literature reports 202 empirical investigations of variables which are in content obviously related to one or several of these characteristics (e.g., democracy, power assertion). The review of these studies reveals a pattern of results that is predominantly in favor of equal rights, but also inconsistent. Studies that seem to point to disadvantages of equal rights, however, can be interpreted as being consistent not only with the assumption of predominantly favorable effects of equal rights, but even with the stronger supposition of the superiority of the concept over the most frequently recommended "authoritative parenting".
This review is complemented firstly by considerations on the cultural relativity of effects, and secondly by a discussion of findings on the question whether humans are evolutionarily predisposed to rather hierarchical or equal rights relationships. Eventually, advantages of the concept of equal rights are being specified, regarding the didactics of parent trainings as well as the progression of research on adult-child relationships.
