How do researchers debrief their participants?

through reciprocal concession

by explaining, after the study concludes, the use and purpose of any deception in the study

by telling them everything about the study before the study begins

through illuminating the dangers of human obedience

The correct answer is: by explaining, after the study concludes, the use and purpose of any deception in the study.

Debriefing is an important part of the research process, especially in studies that involve deception. It involves providing participants with a comprehensive explanation of the study's purpose, procedures, and any deception that was involved. This is typically done after the study concludes to ensure that participants have a clear understanding of the research and to address any questions or concerns they may have. The debriefing process also allows researchers to provide any additional information and resources that participants may need, and to obtain informed consent for using their data.
