Page "Informed consent" Paragraph 49

It is stated in the Ethical Principles of Psychologists and Code of Conduct set by the American Psychological Association, that psychologists may not conduct research that includes a deceptive compartment unless the act is justified by the value and the importance of the results of such study, provided that this could not be obtained in an alternative way.

Moreover, the research should bear no potential harm to the subject as an outcome of deception, be it physical pain or emotional distress.

Finally, a debriefing session is required in which the experimenter discloses to the subject the use of deception in the research he / she was part of and provides the subject with the option of withdrawing his / her data.
