Empirical research has demonstrated the utility of an interest group approach for the study of Soviet politics, as well as for interpreting the politics of tsarist Russia and Eastern European communist systems and the dissident movements. The flowering of group activity in Poland and Czechoslovakia at certain times and the activity of dissent movements show, however, the rudimentary character of “normal” interest groups in the Soviet Union and elsewhere. Although the Soviet system has changed since Stalin's death, it remains fundamentally authoritarian in character. The use of models, such as totalitarian, authoritarian, bureaucratic, corporatist, and pluralist, hinders rather than facilitates an understanding of Soviet politics and of the place of interest groups in that system.
