WJEC A2 Psychology PY3 — Ways of Dealing with Ethical Issues in Psychological Research
In psychological research, “ethical issues” refer to dilemmas and complications that arise when the rights, dignity, and welfare of participants may be threatened by the research process itself. Such issues commonly include risks to psychological or physical well-being, the use of deception, failure to secure proper consent or to maintain privacy and confidentiality, and difficulties that arise when recruiting vulnerable populations like children or those with mental health challenges. This essay explores a range of methods employed by psychological researchers to address these ethical challenges, critically evaluating their effectiveness, limitations, and overall practicality within the context of the British psychological tradition. The essay will consider strategies such as debriefing, presumptive consent, role-play or simulation, adherence to professional ethical codes, scrutiny by ethics committees, and additional safeguards like consent procedures, anonymisation, pilot testing, and researcher training. Finally, the essay will recommend best practices for balancing the pursuit of scientific understanding with the responsibility to protect and respect those who participate.
Evaluation Framework
To assess the effectiveness of each approach, several criteria are used: how well a method protects participants, its impact on the validity and reliability of data, ease of implementation, consistency with established professional and legal standards, and the risk of unintended negative consequences. These criteria are informed by fundamental ethical theories: utilitarian thinking (weighing benefits versus harms) and deontological principles (prioritising inviolable rights and duties). This mixed evaluative perspective is vital, as it reflects the real tensions researchers encounter when attempting to reconcile scientific goals with ethical obligations.Debriefing
Description
Debriefing is the process of providing participants with a full explanation of the research aims, methods, and any deception employed, conducted after their involvement in a study. This typically occurs immediately following participation but may also be followed up later, especially where the research might have caused distress. Debriefing can be delivered verbally or through written documentation and should permit participants to ask questions, raise concerns, and even withdraw their data retrospectively.Practical Elements
An effective debrief should clarify the study’s true purpose, explain any necessity for deception, reassure participants if they experienced negative emotions (for example, after an anxiety-inducing task), and provide clear information about how to withdraw their data if they wish. Contact details for further support or complaints, including referrals to services such as the Samaritans or NHS psychological support, should be offered, especially when harm is a possibility. A record of the debriefing process must be kept, enabling later audit and ensuring compliance with standards such as those set by the British Psychological Society (BPS).Evaluation
Debriefing has clear benefits: it can repair trust and offer redress if the study has caused distress or confusion. For example, in the classic Milgram obedience experiments, thorough debriefing and follow-up were essential in helping participants process their involvement. However, debriefing can never fully ‘undo’ harm already inflicted—trauma or embarrassment experienced during participation cannot always be neutralised after the fact. While debriefing goes some way towards restoring participant autonomy (by allowing data withdrawal), it should not serve as a justification for designs that risk harm. Furthermore, the process does not affect prior behaviour, so it does not introduce bias after the event, but this means it cannot retrospectively alter the quality or validity of the empirical data. In practice, debriefing must be combined with other safeguards.Presumptive Consent
Description
Presumptive consent involves seeking agreement from a group similar in demographic terms to the target participant population. This “proxy” sample is briefed about what the study entails—including any risks or deceptions—and asked whether they would consent, with their collective response used to infer the likely acceptability of the research to real participants.Practical Application
To be ethically defensible, the proxy group must be suitably representative (by age, gender, education, etc.) of the actual sample. They are presented with clear vignettes or scenarios outlining the intended procedures, and their decisions are formally recorded. If a threshold proportion of the proxy group would have consented, the real study might then proceed; this is typically scrutinised by an ethics committee.Evaluation
Presumptive consent can be useful where informing the intended participants fully in advance would jeopardise the study’s aims (for example, increasing demand characteristics). It serves as partial insurance against ethical breaches, though it is not a substitute for actual informed consent. Key issues include the fact that hypothetical agreement may not match what real participants might decide in practice. For instance, people may claim they would tolerate deception in the abstract but respond very differently when genuinely deceived. Thus, while presumptive consent offers a pragmatic solution for certain research designs, especially in cognitive psychology, it is best used alongside more direct safeguards.Roleplay and Simulations
Description
Roleplay and simulation offer alternative methods for exploring psychological phenomena that would be too ethically fraught to study using genuinely exposed participants. Here, individuals are asked to imagine themselves in scenarios (sometimes with the help of actors or virtual reality systems), responding as if those circumstances were real.Practicalities
Effective simulation requires carefully scripted scenarios, thorough training for any actors or confederates, and pilot testing to check that the situation feels plausible to participants. Safety checks and opportunities to withdraw must be built in, and debriefing is as essential here as in any other procedure.Evaluation
Roleplay reduces actual harm, allowing study of sensitive topics (e.g., bystander behaviour in emergencies, or reactions to authority) without placing participants in danger. The BBC Prison Study led by Reicher and Haslam is a noteworthy British example where roleplay and a high degree of ethical oversight were combined, arguably overcoming ethical and methodological criticisms levelled at Zimbardo’s Stanford Prison Experiment. However, the realism of such simulations may be questioned: participants know at some level that it is not “real”, and this may limit the generalisability of findings. Emotional distress can still occur if people become engrossed in their roles, so thorough risk assessment remains essential.Professional Ethical Codes
Description
In the UK, the British Psychological Society's Code of Ethics and Conduct provides a formalised set of principles and standards, including respect for autonomy, beneficence (doing good), non-maleficence (avoiding harm), confidentiality, and integrity. The Code is aligned with both national laws—such as the Data Protection Act and GDPR—and wider European and UN principles.Key Components
Researchers are required to conduct risk assessments, obtain consent, ensure data is kept confidential, and maintain professional competence. The BPS Code is not statutory law, but compliance is expected by employers, research funders, and journals.Evaluation
Ethical codes offer standardisation and protection against historical abuses, such as those highlighted by the Nuremberg Code or infamous 20th century psychological experiments. They aid in training and provide a structure for resolving ambiguous situations. However, codes can be ambiguous or contested; for example, the acceptability of deception is a perpetual grey area. There can also be a lag in adapting to new developments, such as the challenges of online psychological testing or social media research—areas still under active debate.Ethics Committees
Description
Ethics committees, known in the UK as Research Ethics Committees (RECs), are multidisciplinary panels that review research proposals before data is gathered. Their function is to ensure that ethical standards are respected and that the risks to participants are justified by the benefits to society or scientific understanding.Operation
Committees typically include psychologists, laypersons, legal experts, clinicians, and sometimes community representatives. Researchers seeking ethical approval must provide detailed protocols, consent and information sheets, risk assessments, debriefing plans, and data management strategies. Committees may request amendments, impose conditions, or—in rare cases—reject a study outright. Regular monitoring is required, especially in longitudinal or higher-risk research.Evaluation
Independent review can be very effective in detecting overlooked risks and mitigating researcher bias. Nevertheless, inconsistency between panels is an issue—what one committee considers justifiable, another may not. The process can be slow and bureaucratic, leading some researchers to complain about burdensome “red tape”. Furthermore, judgments about the permissible balance of scientific value versus potential harm are inherently subjective.Additional Safeguards and Practices
A comprehensive ethical strategy often requires layering multiple safeguards. Informed consent is essential, and should include adequate, comprehensible information, offered in a voluntary manner and tailored for participants’ backgrounds (including consideration of language and learning difficulties). The right to withdraw—both from participation and data use—must be explicitly communicated, and made practically possible (for example, through coded identifiers for data).Maintaining anonymity and confidentiality is also crucial; data minimisation, secure encrypted storage, and clear protocols for sharing are needed to comply with GDPR. Risk assessments and pilot testing help to foresee and prevent potential harms, and stopping rules allow studies to be terminated at the first sign of distress or adverse effects. Rigorous training for all research staff, including awareness of safeguarding procedures (especially with children or vulnerable adults), enhances the researcher’s capacity to respond to ethical challenges as they arise. Specialist support (such as counsellors on call during sensitive research) and use of technology—carefully managed to protect data—are further layers of protection.
Balancing Scientific Validity and Participant Welfare
One of the perennial tensions in psychological research arises from the clash between the desire for ecological validity, internal control, and the need to protect those involved. For example, deception might be methodologically necessary to avoid demand characteristics, but it can harm participant autonomy and trust. By layering ethical safeguards—committee approval, robust debriefing, training, pilot testing, and aftercare—researchers can attempt to achieve an ethically defensible balance. Moreover, alternative methods such as naturalistic observation, archival analysis, or use of virtual simulations can often replace more intrusive or risky experiments without compromising ethical standards.Recommendations for Best Practice
Based on the above, best practice in research ethics includes pre-registering studies for transparency, minimising deception and always justifying it rigorously, and employing comprehensive debriefing and aftercare procedures. Where roleplay can validly replace harmful conditions, it should be carefully piloted. Presumptive consent should only be supplementary, and not relied upon—especially with vulnerable populations. Ethics committees should be inclusive and well-trained, with community representation. All stages, from consent to debrief, must be documented and stored securely in line with GDPR, and researchers must be continuously trained in both general and study-specific ethical protocols.Conclusion
In sum, no single method is sufficient to resolve all ethical issues in psychological research. Each strategy—whether debriefing, proxy consent, simulation, professional codes, or oversight—offers distinct advantages and potential drawbacks. The most robust and responsible research practice combines several mutually reinforcing methods, keeping participant welfare at the heart of the research enterprise. With transparent processes, rigorous oversight, and a creative approach to study design, it is possible to conduct meaningful psychological research without sacrificing ethical integrity.Examination Tips for WJEC A2
