Since psychological research is concerned with human behaviour, the researcher is expected to follow certain ethics or moral principles while conducting studies. These principles ensure that participants are treated with dignity and respect throughout the research process.

The first principle is respect for persons' privacy and choice to participate in the study. This means that participants should have the freedom to decide whether they want to be part of the research. Voluntary participation is essential, and no one should be forced or coerced into taking part in a psychological enquiry.

The second principle is beneficence, which involves protecting the participants in the study from any harm. Researchers must ensure that their methods do not cause physical, emotional, or psychological harm to the subjects. The well-being of participants should always be a priority.

The third principle is justice, which means sharing the benefits of research with all participants. This ensures fairness and equality in how research outcomes are distributed among those who contributed to the study.

Additionally, psychologists must obtain informed consent from participants before beginning the study. This means explaining the nature and purpose of the research to them. Finally, researchers should also share the results with the participants after the study is completed, maintaining transparency in the research process.
