Ethical issues and exposure to rape stimuli: a reply to Sherif

The three ethical issues raised by Sherif are discussed. In response to the first issue, we recognize the need to measure the effectiveness of our attempts to counteract possible undesirable effects of the research materials. Problems that arise in implementing such an assessment are considered. Also discussed is the possibility that exposure to such materials combined with an effective discrediting communication may have beneficial effects. In addressing the second issue, it is argued that Sherif's criticisms of our alternative data interpretations are unfounded. Finally, Sherif's suggestion to formalize the process of having investigators consider the social policy implications of their research is whole-heartedly supported.
