Discuss ethical implications of research in psychology (16 marks)

Ethical implications in psychological research refer to how research and its findings affect the rights and well-being of individuals and groups, both during the study and once results are published. One key concern is the effect of research on participants, including potential psychological harm or stress caused by procedures or deception. Another implication is the potential influence of research findings on societal views, especially if results are misinterpreted or used to justify discrimination or policies. For example, research suggesting innate differences between groups could reinforce stereotypes. Additionally, the use of findings to influence public policy, such as changes in education or criminal justice systems, raises concerns about how responsibly the research is applied. Studies must also consider the economic impact, as controversial research may affect funding or public trust in psychology.

One ethical implication as discussed involves the potential harm to participants, as seen in Milgram’s obedience studies.
Participants experienced significant stress, believing they were harming another person, which raised concerns about psychological harm and informed consent.
This is problematic because it challenges the ethical responsibility researchers have to protect their participants, even in the pursuit of scientific knowledge.
However, Milgram debriefed participants thoroughly, and many later reported being glad they took part, suggesting that with proper aftercare, ethically questionable studies can still provide valuable insights.

A further implication is the way findings can influence public attitudes or policy. For example, Bowlby’s research into maternal deprivation influenced UK childcare policies in the mid-20th century.
His findings led to widespread belief that mothers should stay at home, which had long-term societal effects on women's roles and family structures.
This raises concerns about how research can unintentionally contribute to social inequality or reinforce gender stereotypes.
Yet, Bowlby’s work also highlighted the importance of early emotional care, which has informed better practices in childcare and adoption, demonstrating that even research with controversial consequences can lead to long-term benefits.

As well as this, ethical implications may  also arise from cultural or socioeconomic bias in research.
Some studies may lack population validity if they primarily use Western, educated, industrialised, rich, and democratic (WEIRD) participants, leading to biased conclusions.
This limits generalisability and may contribute to misconceptions or marginalisation of underrepresented groups.
Researchers are increasingly aware of this and now emphasise reflexivity—acknowledging their own biases and striving for more inclusive research practices.

A final ethical implication is the potential for psychological research to reinforce negative stereotypes or prejudice against certain groups.
For example, research into intelligence differences between ethnic groups, such as that by Herrnstein and Murray in The Bell Curve, suggested that intelligence is largely inherited and varies across races.
This is ethically problematic because such conclusions can be used to justify racist ideologies or discriminatory policies, increasing societal division and inequality.
However, ethical guidelines and peer review processes are now more robust, helping to prevent the publication of biased or harmful interpretations, and encouraging researchers to carefully consider the wider impact of their work.
