For a time, many social psychologists were excited (if not pleased) with Kelman's (1967) suggestions for the use of role playing as an alternative to deception in research. While role playing usually has clear ethical advantages over deception studies, it lacks the control, realism, and explanatory power of the deception experiment; while role playing sometimes produces results apparently similar to the deception experiment (e.g., Stang, 1974a), the results are not always identical, and sometimes are quite different (e.g., Greenberg, 1967;Darroch and Steiner, 1970;Wicker and Bushweiler, 1970). In conformity research, successful deception has often produced different results than role playing (e.g., Horowitz and Rothschild, 1970;Willis and Willis, 1970), supplying partial information to Ss (Horowitz and Rothschild, 1970; but cf. Gallo, Smith and Mumford, 1973) or unsuc-* The author wishes to thank Monte
