Standardized Debriefing: At the conclusion of a study, researchers must provide a full explanation of the research aims and any deception used. This process serves to neutralize any negative effects and ensures the participant leaves the study in the same state they entered.
Anonymization and Confidentiality: To protect privacy, researchers should use coding systems or pseudonyms rather than real names. Data must be stored securely and only reported in a way that prevents the identification of individual participants.
Risk-Benefit Analysis: Before approval, an ethics committee evaluates whether the potential scientific benefits of a study outweigh the potential risks to participants. The goal is always to minimize risk to the lowest possible level.
| Concept | Informed Consent | Retrospective Consent |
|---|---|---|
| Timing | Obtained before the study begins. | Obtained after the study is completed. |
| Application | Standard for most experimental research. | Used when prior knowledge would invalidate results (e.g., covert observation). |
| Requirement | Full disclosure of aims and risks. | Full disclosure during debriefing to validate data use. |
Justifying Deception: When an exam question asks about deception, always explain why it was necessary (e.g., to avoid demand characteristics) and how it was mitigated (e.g., through a comprehensive debriefing).
Designing Safeguards: If asked to design a study, explicitly mention specific ethical actions, such as 'Participants will be given a written consent form' or 'A professional counselor will be available if the task causes distress.'
Identifying Conflicts: Be prepared to discuss how different ethical principles might conflict, such as the need for scientific validity (requiring deception) versus the principle of respect (requiring total honesty).
The 'No Harm' Fallacy: A common mistake is assuming that if no physical pain is involved, there is no risk of harm. Researchers must equally consider psychological harm, such as stress, embarrassment, or loss of self-esteem.
Consent is Not a Waiver: Obtaining a signature on a consent form does not absolve the researcher of responsibility. If a participant becomes distressed during the study, the researcher must intervene, regardless of the prior consent.
Confidentiality vs. Anonymity: These are often confused. Anonymity means the researcher doesn't know who the participant is; confidentiality means the researcher knows but promises not to reveal the identity to others.
