Systematic Political Theory: Observations on the Group Approach

Abstract

Of the spate of articles on interest group behavior and interest group theory which have appeared since the “rediscovery” of Bentley, only a few have been mildly critical. Two American commentators have criticized the vagueness of certain terms and a British observer has noted that, somehow, empirical research on group behavior rarely makes use of the theoretical schemes which have been devised.But surely if we are to accept the claim of the group theorists that this is indeed the key to a science of politics, it is legitimate to ask that they submit their propositions to the tests imposed by science as a method. Perhaps the gap between research and theory stems less from a lack of data than from some limitations inherent in the group approach itself? This, in fact, is the argument of the present essay. The failure of group theory to serve as an adequate guide to research is the result both of the logical inconsistencies of its propositions and of its inability to explain what it purports to explain. The two weaknesses are related, for in their empirical work group theorists are constantly forced into inconsistencies as a result of the inability of the theory to deal with certain dimensions of experience. The ability of those who use the approach to ignore these consequences stems both from a certain looseness of vocabulary and a tendency, not limited to American scholars, to universalize their own political experience.
