The purpose of this study was to examine the nature and extent to which cultural differences bear on perceptions of ethical Organizational Development consulting behaviors. U.S. (n=118) and Taiwanese (n=267) business students evaluated eleven vignettes depicting potential ethical dilemmas. Respondents judged the ethicality of each vignette, the likelihood of the event's occurrence and the party responsible for the event's occurrence. Multivariate Analyses of Variance revealed significant cultural differences in perceptions of ethicality, and group differences in perceptions of the events' likelihood (...) of occurrence. U.S. subjects provided higher ethicality ratings than the Taiwanese, and lower ratings on the likelihood of occurrence. Response distributions resulting from the identification of the responsible party were similar for six of the eleven vignettes. When differences did occur, it appeared that the Taiwanese were more inclined than the U.S. subjects to view responsibility as shared by the client and the consultant. The results suggest the need for the incorporation of cultural differences in a code of ethics for the profession and the need for cross-cultural ethics training for partitioners. (shrink)
