Abstract: Recent developments in the history, philosophy, psychology, and sociology of science raise serious challenges to our traditional notions about the decisive power of experiments in the development of scientific knowledge. These developments suggest that the power of an experiment is only as strong as the clarity af the basic assumptions which underlie it. Such assumptions not only underlie laboratory experimentation but social evaluation research as well. A dialectical methodology is proposedfor assessing the influence of key assumptions in both settings. Among other conclusions, analysis of the role and influence of key assumptions suggests an additional source of experimental error, termed the error of the third kind, or E III. E III is defined and discussed as the probability af conducting the "wrong" experiment when one should have conducted the "right" experiment.
