Research Ethics: Evaluating the Price of Knowledge
1. Introduction to Ethics & IRB
- Why ethics? Protects participants, ensures valid science, builds trust.
- APA Principles:
- Informed consent
- Protection from harm
- Right to withdraw
- Confidentiality
- Debriefing after deception
- IRB (Institutional Review Board): Reviews research, balances risks vs benefits.
Q: Why do you think psychology needs stricter rules than some other fields?
Answer
A: Because psychology often manipulates emotions, stress, and behavior directly — risks of harm can be invisible but real. IRBs make sure those risks are minimized.
2. Famous Studies & Ethical Issues
Milgram’s Obedience Study
Deception, stress, questionable debriefing.
Q: Why did participants obey even though they were distressed?
Answer
A: Authority pressure, diffusion of responsibility, social norms. Shows power of authority but raised ethical alarms.
Zimbardo’s Stanford Prison Experiment
No informed consent about potential harm, trauma, no right to withdraw.
Q: Should Zimbardo have stopped the study sooner?
Answer
A: Yes — ethical guidelines require stopping if harm is evident. The study became abusive within days.
Watson & Rayner’s Little Albert
No protection from harm, no desensitization, no real consent.
Q: What should researchers have done differently?
Answer
A: Provided informed consent, avoided traumatizing a child, deconditioned fear afterward.
Monster Study (Wendell Johnson)
Stuttering study on orphans. Negative feedback induced long-term harm.
Q: Why is this especially unethical with orphans?
Answer
A: Vulnerable population, no guardian consent, long-lasting psychological harm. Also, lack of debriefing or reversal of harm.
MKULTRA (CIA Mind Control Experiments)
Government-funded experiments in the 1950s–60s using LSD, hypnosis, and sensory deprivation on unwitting participants to test mind control. Many subjects experienced trauma without consent.
Q: Why is MKULTRA considered one of the most extreme ethical violations?
Answer
A: Participants did not consent, many suffered permanent psychological damage, and it violated basic human rights. It showed how political agendas can override scientific responsibility.
Psychology of Interrogation (Domestic Crime)
Psychologists have been involved in designing interrogation methods for police — such as the Reid Technique. While legal, critics argue it can lead to false confessions due to coercion and psychological manipulation.
Q: Why is psychological interrogation controversial?
Answer
A: Because even if no physical harm occurs, manipulative tactics can pressure innocent people into confessing. The ethical line blurs between “science applied to justice” and “abuse of psychology.”
Psychology of Interrogation (Counter-Terrorism)
After 9/11, some psychologists consulted with military and intelligence agencies to design “enhanced interrogation techniques” (e.g., sleep deprivation, stress positions). These practices have been criticized as unethical and akin to torture.
Q: Why does counter-terrorism interrogation remain an ethical debate?
Answer
A: Proponents argue it protects national security; critics argue it crosses the line into torture, violates human rights, and undermines psychology’s professional ethics. APA later banned psychologists from participating in such interrogations.
3. Ethics Scenarios
Scenario A
A researcher tells students they’ll be in a “memory study,” but the real purpose is to measure stress while being embarrassed in front of peers.
Q: What are the main ethical issues here?
Answer
Deception, psychological harm, lack of informed consent. Fix: Allow deception only if no harm is caused and debrief thoroughly.
Scenario B
A psychologist wants to test whether sleep deprivation impacts test scores, so students are kept awake for 36 hours straight.
Q: What are the main ethical issues here?
Answer
Physical harm, minors at risk, unsafe sleep deprivation. Fix: Use adults, limit to safe hours, monitor health closely.
Scenario C
An experimenter records student conversations in the cafeteria without their knowledge to study “natural language use.”
Q: What are the main ethical issues here?
Answer
Privacy violation, no consent. Fix: Require consent or anonymize/public-space-only data.
4. Three-Team Ethics Debate
Dilemma: A new VR simulation is designed to study fear in teens. Realistic scenarios include heights, darkness, and social rejection. Researchers argue it could help anxiety treatments. Some teens may feel distress.
- Team 1 (Pro-Research): Benefits outweigh risks if monitored.
- Team 2 (Strict IRB): Too risky for minors, restrict or redesign.
- Team 3 (Middle Ground): Allow with modifications (parent consent, safety monitoring, exit option).
Q: What IRB principles apply here?
Answer
Parental consent, minimal harm, right to withdraw, and protecting vulnerable populations.
5. Wrap-Up Reflection
Q: If you were on an IRB, what rule would matter most to you, and why?
Sample Answers
