Abstract

In this paper, it is argued that efforts to devise a unified theory of psychological knowledge are problematic, and that the cultivation of multiple theoretical lenses contributes to a more useful and self-aware psychology. Various forms of unificationism, and the rationales behind such efforts, are discussed. Two drawbacks of unified theories are then explored, along with the virtues of multiplicity. First, the assertion of a single perspective on psychological reality unduly limits the possibilities for usefully conceptualizing and engaging with the world; it can also hamper critical reflection on the sociocultural embedded-ness of psychologists' theories and practices. Second, the type of unified theory likely to achieve hegemony will not be congenial to sociocultural theories and methods. 2012 APA, all rights reserved)
