When is deception permitted in research?

Deception in research is permitted when it is justified by the study's potential benefits, and when it does not cause significant harm to participants. Researchers must ensure that the deception does not violate ethical standards, including informed consent, and that participants are debriefed afterward to clarify the true nature of the study. Additionally, deception should be minimized and only used when alternative methods are not feasible. Ethical review boards often assess the appropriateness of deception in research proposals.
