Although informed consent is a primary mechanism for ensuring the ethical treatment of human participants in research, both federal guidelines and American Psychological Association ethical standards recognize that exceptions to it are reasonable under certain conditions. However, agreement about what constitutes a reasonable exception to informed consent is sometimes lacking. We presented the same protocols to samples of respondents drawn from 4 populations: Institutional review board (IRB) members, managers, employees, and university faculty who were not members of IRBs. Differences in (...) perceptions of IRB members from the other samples with respect to the risks of the protocols without informed consent and on the feasibility of conducting the research in employment organizations are discussed in terms of implications for industrial and organizational psychology research.
