What is one way faculty researchers can avoid undue influence over student subjects?

Avoiding the recruitment of their own students is an effective way for faculty researchers to mitigate undue influence over student subjects. When faculty members recruit their own students for research, there is a potential risk of coercion or perceived pressure to participate, which can compromise the voluntary nature of consent. Students may feel they have to participate in order to receive favorable treatment or avoid negative consequences in their academic assessments or relationships with the faculty member.

By not recruiting their own students, researchers can create a more neutral environment where participation is strictly voluntary, thus enhancing the integrity of the research process. This practice helps ensure that the decision to participate is based solely on the student's willingness rather than any implicit or explicit pressure from the faculty member, fostering an ethical approach to research involving human subjects.

The other options involve various research practices, but none directly address the significant concern of perceived or actual pressure that can arise from a faculty-subordinate relationship in an academic setting.
