Occasionally, psychological experiments involve deception, which may be used if informing participants of the nature of the experiment might bias results.
Stanley Milgram conducted obedience experiments in which he convinced participants that they were administering painful electric shocks to other participants, when, in fact, no shocks were given.
Institutional Review Boards (IRBs) assess research plans before the research is approved to ensure that it meets all ethical standards.
Participants must give informed consent; in other words, they agree to participate in the study only after they have been told what their participation entails.
After the experiment is concluded, participants must receive a debriefing, in which they are told the exact purpose of their participation in the research and of any deception that may have been used in the process of experimentation.
Confidentiality is another area of concern for psychology.
