Introduction to Ethics in Psychology

In Psychology, ethics are like the "rules of the road." When psychologists carry out research, they can't just do whatever they want to get an answer. They must follow strict guidelines to ensure that their participants (the people taking part) are treated fairly and are not harmed. In this chapter, we will look at the five main ethical issues you need to know for your exam and how researchers manage them.

The Five Key Ethical Issues

To help you remember these, try the mnemonic "D-R-I-P-C" (Deception, Right to Withdraw, Informed Consent, Protection, Confidentiality).

1. Informed Consent

Informed consent means telling participants exactly what the study involves before they agree to take part. They should know the aims and what they will be asked to do.

  • The Challenge: Sometimes, if you tell a participant exactly what you are looking for, they might change their behaviour (this is called demand characteristics), which ruins the results.
  • Dealing with it: Researchers should get participants to sign a consent form. For children (like in Piaget and Inhelder’s Three Mountains task), researchers must get consent from parents or guardians.

2. Deception

Deception is when a researcher withholds information or deliberately misleads participants about the true aim of the study.

  • The Challenge: While it helps keep behaviour natural, it can make participants feel foolish or untrusting of psychologists in the future.
  • Dealing with it: Participants should be debriefed. A debrief happens at the end of the study where the researcher explains the true aim and reveals any "tricks" used.

3. Confidentiality

Confidentiality is the right to have personal data kept private. This means names, addresses, or any identifying features should not be published.

  • The Challenge: In case studies, it can be hard to hide who a person is if their life story is very unique.
  • Dealing with it: Researchers use numbers or false names (pseudonyms) to refer to participants. For example, in Caspi et al. (2003), the DNA data of the participants had to be kept strictly confidential.

4. Right to Withdraw

Participants should be told they can leave the study at any time if they feel uncomfortable. They should also be allowed to "withdraw their data"—this means even after the study is over, they can ask the researcher to delete their results.

  • The Challenge: If too many people leave, the researcher might not have enough data to finish the study.
  • Dealing with it: Researchers must make it clear from the very beginning that there is no pressure to stay and no penalty for leaving.

5. Protection of Participants

This is the most important rule: participants must be protected from physical and psychological harm. They should leave the study in the same state they entered it.

  • The Challenge: Some research into stressful topics (like memory loss or social pressure) can naturally cause a bit of stress.
  • Dealing with it: If a study is likely to cause stress, the researcher must provide support, such as counseling, and stop the study if the harm becomes too great.

Quick Review: Think of ethics as a "safety net" for participants. If a researcher can't guarantee safety or privacy, the study should usually not happen!

Dealing with Ethical Issues: Summary Table

Here is how psychologists "fix" or handle the issues mentioned above:

Issue: Deception
Solution: Debriefing (explaining everything at the end).

Issue: Informed Consent
Solution: Consent Forms (getting a signature before starting).

Issue: Confidentiality
Solution: Anonymity (using numbers instead of names).

Issue: Protection of Participants
Solution: Right to Withdraw and providing support.

Issues and Debates: Ethics in the Core Topics

The Edexcel syllabus requires you to explain ethical issues using examples from the topics you have already studied (Topics 1-5). Here are some key links:

Topic 5: Social Influence

The study by Haney, Banks, and Zimbardo (1973) (The Stanford Prison Experiment) is a classic example of ethical problems.
Problem: Participants were not protected from harm; "prisoners" became extremely distressed.
Problem: The right to withdraw was made very difficult, as the "warden" (Zimbardo) pressured them to stay.

Another example is Piliavin et al. (1969) (The subway study). Because this was a field experiment on a train, the participants did not give informed consent and could not be debriefed, as they simply walked off the train at their stop.

Topic 4: The Brain and Neuropsychology

When studying patients with brain damage, such as the case of Phineas Gage (studied by Damasio et al., 1994), confidentiality is vital because these individuals are often famous in the scientific world. Researchers must ensure that private medical records are handled with care.

Topic 3: Psychological Problems

In research like Caspi et al. (2003), which looked at genes and depression, protection of participants is key. Learning that you have a "depression gene" could cause psychological distress, so researchers must handle this information sensitively.

Common Mistakes to Avoid

1. Confusing "Ethics" with "Morals": While they are related, in Psychology, "ethics" refers to the specific professional guidelines set by organizations (like the British Psychological Society). "Morals" refers to a person's individual sense of right and wrong.

2. Thinking Deception is Always Banned: Deception is allowed, but only if it is necessary for the study and if the participants are debriefed properly afterward.

3. Forgetting the Right to Withdraw: Remember, this applies even after the study. A participant can call the researcher a week later and say, "I don't want my data used," and the researcher must obey.

Key Takeaway

Ethical guidelines exist to balance the needs of science (the need to find out new things) with the rights of the individual. In the exam, always look at a study and ask: "Did they know what they were doing?", "Were they safe?", and "Can they be identified?"
