    Component 3: Ethical costs of conducting research — Eduqas A-Level Psychology

    Verified courseTeaching note checked against the official specification.

    Ethical costs of conducting research in psychology refer to the moral obligations researchers have to protect participants from harm, obtain informed consent, maintain confidentiality, and ensure the benefits of research outweigh any risks. In Eduqas A-Level Psychology Component 3, students must evaluate these ethical considerations in the context of socially sensitive research and the role of ethical committees.

    Component 3: Ethical costs of conducting research explained

    Component 3: Ethical costs of conducting research covers 4 specification points, including benefits to society and the economy and individual participants.

    Open a point below for its explanation and revision guidance.

    benefits to society and the economy

    Ethical costs of research are weighed against the benefits it brings to society and the economy. Teach learners to identify concrete benefits: improved treatments and public health guidance, safer workplaces, more effective education, and economic gains from a healthier or more productive population. Then require them to balance those benefits against the costs to participants, such as distress, deception or loss of confidentiality, and to judge whether the benefit justifies the cost. For example, research informing mental health interventions may benefit many people and reduce costs to health services, yet still impose costs on individual participants. Assessment rewards a reasoned cost-benefit argument that names specific benefits, explains the mechanism by which they arise, and evaluates the trade-off rather than asserting that benefits always outweigh costs.

    individual participants

    This element asks you to weigh the ethical costs that research imposes on the individual people who take part, rather than on the wider group or society. In an extended answer, identify the specific cost to a named kind of participant and explain the mechanism that produces it. For example, a study that deceives participants about the true aim removes their ability to give fully informed consent, so they cannot decide whether they wish to be involved; a study that exposes them to stress or failure may leave psychological harm; a study that publishes identifiable data breaches confidentiality and privacy. Balance the cost against the benefit and against safeguards such as debriefing, the right to withdraw, informed consent and anonymisation, and judge whether the safeguard removes the cost or only reduces it.

    potentially negative consequences for society

    This element asks you to consider how research can harm groups or society beyond the individual participant. In an extended answer, identify a specific social consequence and explain the pathway that produces it. For example, findings that appear to show a group is less able than another may be used to justify discrimination or to shape policy unfairly, and research funded by a commercial body may be seen to serve that body's interests rather than the public good. Consider also the effect on public trust: if participants feel misled, willingness to take part in future research may fall. Weigh the potential negative consequence against the likely benefit and against safeguards such as careful reporting, peer review and transparent funding, and judge how far the risk is managed.

    risk management techniques used by Psychologists

    Risk management means identifying what could harm participants, researchers or others in a study, judging how likely and how serious each harm is, and putting proportionate steps in place before data collection begins. Psychologists typically start with a risk assessment: they list hazards such as distress, disclosure of sensitive information, physical strain or loss of anonymity, then rate each as low, medium or high. Controls follow from that rating, for example piloting a sensitive interview schedule, agreeing a distress protocol with a supervisor, using anonymised identifiers, securing data storage, briefing and debriefing participants, and knowing when to stop a session or refer someone for support. Risk management is reviewed and updated as the study develops, and it is recorded so that an ethics committee can scrutinise the reasoning.

    Component 3: Ethical costs of conducting research exam tips

    Topic Overview

    This topic examines the ethical principles that govern psychological research, focusing on the costs to participants, researchers, and society. It covers key guidelines from the BPS Code of Ethics and Conduct, including informed consent, deception, protection from harm, confidentiality, and the right to withdraw. Understanding these costs is essential for evaluating the validity and acceptability of classic and contemporary studies.

    In the wider context of Eduqas A-Level Psychology, ethical costs are integral to the 'Issues and Debates' component and are often assessed in relation to socially sensitive research. Students must be able to apply ethical principles to specific studies, weigh costs against benefits, and discuss how ethical committees balance scientific progress with participant welfare. This topic also prepares students for designing their own ethical research proposals.

    Key Concepts
    • →Informed consent: Participants must be given comprehensive information about the study's aims, procedures, and potential risks to make a voluntary decision to participate.
    • →Deception: Deliberately misleading participants about the true purpose or procedures of a study; it is only acceptable if it is necessary and does not cause undue harm, and participants must be debriefed.
    • →Protection from harm: Researchers must ensure participants are not exposed to physical or psychological harm, including stress, embarrassment, or pain; risks should be no greater than in everyday life.
    • →Confidentiality: Participants' data must be kept anonymous and secure, unless disclosure is agreed; this is crucial for sensitive topics.
    • →Socially sensitive research: Studies that could have implications for groups or society, requiring special ethical consideration due to potential stigmatisation or misuse of findings.
    Marking Points
    • Identifies specific benefits of research to society, such as improved health, education or public policy.
    • Explains the mechanism by which findings produce economic benefit, such as reduced healthcare costs or greater productivity.
    • Balances the stated benefits against the ethical costs borne by participants, naming those costs explicitly.
    • Evaluates whether the benefits justify the costs, reaching a reasoned judgement rather than an assertion.
    • Identifies a specific cost to individual participants, such as loss of informed consent through deception, psychological harm, breach of confidentiality or invasion of privacy.
    • Explains the mechanism by which the cost arises, linking a procedural feature of the study to its effect on the participant.
    • Weighs the cost against the potential benefit and against safeguards such as debriefing, anonymisation and the right to withdraw.
    • Judges whether a safeguard removes the ethical cost or merely reduces it, reaching a supported conclusion.
    • Identifies a specific potential negative consequence for society, such as discrimination, stigmatisation of a group, misuse of findings or erosion of public trust.
    • Explains the pathway from the research to the social consequence, showing how findings could be interpreted or applied.
    • Weighs the potential social cost against the likely benefit and against safeguards such as careful reporting and transparent funding.
    • Reaches a supported judgement about how far the risk to society is managed or remains serious.
    • Identifies a specific hazard in a named study context and states a proportionate control for it
    • Distinguishes a preventive control, such as piloting or anonymisation, from a reactive step taken after harm has occurred
    • Explains that risk is judged by combining likelihood with severity rather than by severity alone
    • Recognises that risk management is documented and reviewed so an ethics committee can scrutinise the decisions
    Examiner Tips
    • 💡Name the benefit, the group who gains and the route by which the gain occurs, so the point is concrete.
    • 💡Pair each benefit with a corresponding ethical cost to build a genuine cost-benefit argument.
    • 💡Conclude with a qualified judgement that acknowledges when the balance might tip the other way.
    • 💡Name the participant group and the procedure before explaining the cost, so the mechanism is clear.
    • 💡Use one developed example rather than several undeveloped ones.
    • 💡Finish with an explicit judgement about how serious the cost is and why.
    • 💡Specify the social group or public interest affected, not just 'society' in general.
    • 💡Explain the mechanism linking findings to consequence before judging severity.
    • 💡Conclude with a clear judgement about whether the risk is acceptable.
    • 💡Read the stem for the study context first, because the best control depends on the specific hazard described
    • 💡Eliminate options that describe an apology or compensation after harm rather than a preventive technique
    • 💡Check whether an option names both the hazard and the control, since a control with no stated hazard is usually too vague
    • 💡Always use specific terminology from the BPS Code of Ethics, such as 'informed consent', 'debriefing', 'protection from harm', and 'right to withdraw', to show precise knowledge.
    • 💡When evaluating ethical costs, provide a balanced argument by discussing both the costs and the benefits of the research, and refer to how ethical guidelines have evolved over time.
    • 💡Apply ethical principles to named studies (e.g., Milgram, Zimbardo, Bowlby) to demonstrate understanding and avoid generic answers.
    Common Mistakes
    • Claims that research benefits society without naming a specific benefit or mechanism; specify the benefit and how it arises.
    • Treats economic benefit as automatically outweighing participant harm; weigh both sides and justify the judgement.
    • Confuses the benefit to researchers or institutions with benefit to society; distinguish who actually gains.
    • Confuses costs to individual participants with costs to society; keep the focus on the person who takes part.
    • Lists ethical principles without explaining how a procedure produces a cost for the participant; link each principle to a concrete effect.
    • Assumes debriefing erases all harm; consider whether it fully restores the participant's position.
    • Restates costs to individual participants instead of addressing consequences for society; shift the focus to groups and public effects.
    • Asserts that findings will cause harm without explaining the pathway; show how the research could be interpreted or applied.
    • Treats any social risk as automatically disqualifying; weigh it against benefit and safeguards.
    • Treats a risk assessment as a single form completed once; describe it instead as an ongoing process that is reviewed as the study develops
    • Confuses debriefing with risk management itself; present debriefing as one control among several, not the whole procedure
    • Assumes low likelihood means no control is needed; explain that severity still determines the response
    • Misconception: Ethical guidelines are absolute and must never be broken. Correction: Ethical costs are relative; researchers may use deception if it is justified and does not cause harm, and ethical committees weigh costs against benefits.
    • Misconception: Informed consent means simply getting a signature. Correction: Informed consent requires full disclosure of the study's purpose and procedures, and participants must be competent to consent; in cases like Milgram's, presumptive consent or debriefing may be used.
    • Misconception: Confidentiality means participants' names are not used. Correction: Confidentiality also involves secure data storage, anonymisation, and not sharing identifiable information without consent.

    Command Word Expectations (EDUQAS)
    Explain

    Provide detailed reasons or mechanisms, showing cause and effect. For example, 'Explain one ethical cost' requires a clear definition, an example, and why it is a cost.

    Discuss

    Present a balanced argument considering multiple perspectives, including strengths and weaknesses. For ethical costs, discuss both the costs and benefits, and reach a justified conclusion.

    Evaluate

    Make a judgement based on evidence and reasoning, weighing up the importance or value of something. For ethical costs, assess the extent to which costs are justified by benefits, and consider alternative viewpoints.

    How Students Lose Marks (Examiner Pitfalls)
    Pitfall: Students often confuse ethical guidelines with ethical issues, or fail to apply them to specific research scenarios, leading to vague answers that do not address the question.
    ❌ Weak Answer (Loses Marks):Ethical costs are things like consent and confidentiality. Researchers should follow them to be ethical.
    Example improved answer:Ethical costs in research include the potential psychological or physical harm to participants, such as in Milgram's obedience study where participants experienced extreme stress. Researchers must obtain informed consent, debrief participants, and ensure confidentiality. However, these costs must be weighed against the scientific benefits, such as understanding obedience to authority. Ethical committees assess this balance before approving research.
    Examiner Tip: Always link each ethical cost to a specific example from a named study and explain how it could be managed or justified. Use terms like 'informed consent', 'debriefing', 'protection from harm', and 'confidentiality' precisely.
    Pitfall: Students frequently ignore the concept of 'socially sensitive research' and its ethical implications, or they treat ethical costs as absolute rather than relative to the research context.
    ❌ Weak Answer (Loses Marks):Socially sensitive research is unethical because it can harm groups. Researchers should avoid it.
    Example improved answer:Socially sensitive research, such as studies on race and intelligence, can have ethical costs including stigmatisation of groups and misuse of findings. However, it can also yield benefits like reducing prejudice. Ethical costs are not absolute; they must be evaluated in terms of the potential harm versus the potential societal benefit. Researchers should follow guidelines from the BPS Code of Ethics and Conduct, which emphasises responsibility and integrity.
    Examiner Tip: In questions about socially sensitive research, discuss both costs and benefits, and refer to the BPS guidelines. Use examples like Bowlby's maternal deprivation theory or Jensen's work on IQ to illustrate.
    Step-by-Step Worked Solutions

    Question: Explain two ethical costs that researchers must consider when conducting psychological research. (6 marks)

    1. 1.Step 1: Identify two ethical costs from the BPS guidelines, such as protection from harm and informed consent.
    2. 2.Step 2: For each, explain what the cost involves and why it is important, using a specific example from a named study.
    3. 3.Step 3: Conclude by stating how researchers can address these costs, e.g., through debriefing or ethical committee approval.
    Final Answer: One ethical cost is protection from harm: participants should not experience physical or psychological harm. For example, in Zimbardo's prison study, participants experienced severe stress, which was an ethical cost. Researchers can minimise this by stopping the study early and providing debriefing. Another cost is lack of informed consent: participants must be told the true aims of the study. In Milgram's study, participants were deceived about the shocks, so they could not give informed consent. This can be addressed by obtaining presumptive consent or debriefing afterwards.

    Question: Discuss the ethical costs of conducting research into obedience to authority. (12 marks)

    1. 1.Step 1: Outline the ethical costs in obedience research, such as deception, protection from harm, and right to withdraw.
    2. 2.Step 2: Use evidence from Milgram's study and variations to illustrate these costs, e.g., participants showed signs of extreme stress.
    3. 3.Step 3: Evaluate the costs against the benefits, such as increased understanding of destructive obedience, and discuss how ethical guidelines have evolved.
    4. 4.Step 4: Conclude with a balanced judgement on whether the costs were justified.
    Final Answer: Ethical costs in obedience research include deception, as participants in Milgram's study were told the shocks were real, and protection from harm, as many participants experienced nervous laughter and seizures. The right to withdraw was also compromised as the experimenter prompted them to continue. However, the benefits include valuable insights into obedience, which have been used to understand atrocities like the Holocaust. Modern ethical guidelines would require debriefing and follow-up care. While the costs were high, the scientific benefits may justify them, but researchers must now adhere to stricter ethical standards.
    Active Recall Memory Test
    What are the four ethical principles in the BPS Code of Ethics?
    Key Fact: Respect, Competence, Responsibility, and Integrity.
    Define 'informed consent' and explain why it is an ethical cost when it is not obtained.
    Key Fact: Informed consent is when participants are fully informed about the study's aims, procedures, and risks, and voluntarily agree to take part. Without it, participants are deceived and cannot make an autonomous choice, which is an ethical cost as it violates their rights.
    Give an example of a study with high ethical costs and explain how the costs could be justified.
    Key Fact: Milgram's obedience study had high ethical costs: deception, protection from harm, and right to withdraw. It could be justified by the significant insights into destructive obedience, which have real-world applications, and participants were debriefed and followed up.
    What is socially sensitive research and why does it have ethical costs?
    Key Fact: Socially sensitive research studies topics that could have implications for groups or society, such as race, sexuality, or mental illness. It has ethical costs because findings can be misused to stigmatise or discriminate against groups, causing psychological harm.
    Frequently Asked Questions
    What are the ethical costs of conducting research in psychology?
    Ethical costs refer to the potential harms or moral issues that arise from research, such as psychological or physical harm to participants, loss of confidentiality, deception, and lack of informed consent. Researchers must weigh these costs against the scientific benefits and follow guidelines like the BPS Code of Ethics to minimise harm. Ethical committees assess research proposals to ensure costs are justified.
    How do you evaluate ethical costs in the Milgram study?
    In Milgram's study, ethical costs included deception (participants thought shocks were real), protection from harm (participants showed extreme stress), and right to withdraw (prods were used to keep them going). However, the benefits included valuable insights into obedience to authority. The costs were high, but Milgram debriefed participants and found no long-term harm, so some argue the costs were justified given the scientific contribution.
    What is socially sensitive research and why is it an ethical issue?
    Socially sensitive research studies topics that could have implications for groups or society, such as race, gender, or mental health. It is an ethical issue because findings can be misused to justify discrimination, stigmatise groups, or cause psychological harm. Researchers must be especially careful to follow ethical guidelines and consider the potential impact of their work on society.
    What are the BPS ethical guidelines for psychological research?
    The BPS Code of Ethics and Conduct is based on four principles: respect (for persons and their autonomy), competence (maintaining high standards), responsibility (to participants and society), and integrity (honesty and accuracy). It includes specific guidelines on informed consent, deception, debriefing, confidentiality, and protection from harm. Researchers must adhere to these to ensure ethical practice.
    How can ethical costs be reduced in psychological research?
    Ethical costs can be reduced by obtaining informed consent, avoiding deception where possible, debriefing participants fully, ensuring confidentiality, and allowing the right to withdraw. Researchers should also conduct a risk assessment and have their study approved by an ethics committee. In cases where deception is necessary, presumptive consent or retrospective consent may be used.
    What is the difference between ethical costs and ethical benefits?
    Ethical costs are the potential harms or negative consequences of research, such as stress to participants or misuse of findings. Ethical benefits are the positive outcomes, such as advancing knowledge, improving interventions, or benefiting society. Researchers must balance these, ensuring that benefits outweigh costs and that costs are minimised. Ethical committees evaluate this balance before approving research.
