Fundamental Errors Of Reasoning In The Psychology Of Impersonality
Abstract
In this article we raise the issue of whether research on individual differences contributes to personality theory. Conventional wisdom has long held that it does. In this article we defend the opposing view. We demonstrate that the fundamental and irreparable problem is that statistical knowledge produced through studies of individual differences variables produces knowledge about groups of organisms, not individual organisms. Our epistemological analysis has implications for three historically basic themes in classical nomotheticism: (a) the search for basic human tendencies, (b) the debate concerning the (in)consistency of personality, and (c) behavioral predication and the establishment of nomothetic ‘laws’ of personality functioning.
