The contribution which the empirical results of evaluations research makes to dispute processing knowledge is discussed, along with the limitations of current ways of framing evaluations. Elements of social science research that shape dispute resolution, including the new formalism and impact analysis are also discussed. New formalism is criticized as a limited and limiting perspective that has blinded researchers to the significance of certain important data. Tables provide information on primary and hybrid dispute resolution processes. Appendix includes a bibliography of dispute processing evaluations. 75 footnotes.
