Debriefing (experimental)

In psychological research, a debriefing is a short interview that takes place between researchers and experimental subjects immediately following their participation in a experiment. The debriefing is an important ethical consideration to make sure that participants are fully informed about, and not harmed in any way by, their experience in an experiment.

Along with informed consent, the debriefing is considered to be a fundamental ethical precaution in research involving human beings. It is especially important in social psychology experiments that use deception. Debriefing is typically not used in surveys, observational studies, or other forms of research that involve no deception and minimal risk to participants.

Methodological advantages of a debriefing include the ability of researchers to check the effectiveness of a manipulation, or to identify participants who were able to guess the hypothesis or spot a deception. If the data have been compromised in this way, then those participants should be excluded from the analysis. Many psychologists feel that these benefits justify a postexperimental followup even in the absence of deception or stressful procedures.
