The use of deception in research is generally permitted so long as participants are debriefed at the conclusion of their participation. Several authoritative research ethics guidelines allow investigators to omit debriefing under certain circumstances, however. Here we examine various justifications for forgoing debriefing in deceptive research, including concerns about subject pool contamination, the risk that revealing the deception will be harmful or distressing to participants, and issues of practicability. We conclude that, contrary to current practice, omitting debriefing is ethically acceptable (...) only when debriefing is impracticable, the deception is innocuous, and no reasonable person would object to involvement in the research.

This article is a reconsideration of Tesch's (1977) ethical, educational, and methodological functions for debriefing through a literature review and an Internet survey of authors of articles published in the Journal of Personality and Social Psychology and Journal of Traumatic Stress . We advocate for a larger ethical role for debriefing in nondeception research. The educational function of debriefing is examined in light of the continued popularity of undergraduate participant pools. A case is made for the methodological function of debriefing (...) to clarify aspects of research participation. Recommendations are made to improve the conducting and reporting of debriefings.
