Which of the following describes the role of a researcher who deceives subjects?

The option stating that the researcher jeopardizes the integrity of the research accurately reflects the ethical considerations surrounding the use of deception in research. When researchers choose to deceive participants about the study's true purpose or design, it can lead to significant concerns regarding the validity and reliability of the findings. Deception can compromise trust between researchers and participants, which is crucial for ethical research practice.

Moreover, if participants later learn that they were deceived, they may question the findings of the study or feel manipulated, leading to a lack of confidence in the research as a whole. This breach of trust can also impact future research efforts, as participants may become wary of taking part in studies. Ethical guidelines emphasize the importance of informed consent, where subjects are made aware of the nature and purpose of the research, so employing deception must be handled with extreme caution to avoid undermining the study's credibility.

The other options reflect different aspects of research ethics but do not specifically address the consequences of deception in the same way. For instance, informing subjects of the study's purpose and the restriction against conducting experiments on minors are standards of ethical research that prioritize transparency and protection, while gathering unbiased data is a goal common to many research methodologies. However, these points do not capture the immediate
