What ethical principle emphasizes the need for fair participant selection?

The principle that emphasizes the need for fair participant selection is justice. This ethical principle focuses on the equitable distribution of both the benefits and burdens of research among different populations. Justice ensures that no group is unfairly burdened by research participation, while also allowing that the benefits derived from research are shared fairly among all groups.

In the context of research, this means that vulnerable populations should not be disproportionately involved in research that places them at risk without the potential for benefit to themselves or their communities. Instead, the selection of participants should be conducted in such a way that it promotes fairness, avoiding exploitation and ensuring equal access to the benefits of research outcomes for all groups.

This principle is fundamental in the oversight of ethical research practices, helping to mitigate biases in participant recruitment and ensuring that research contributes positively to societal welfare. Other principles, such as respect for persons, focus on the autonomy and informed consent of individuals involved in research, and beneficence is concerned with maximizing benefits and minimizing harm. Accountability involves responsibility in research practices but does not specifically address participant selection. Therefore, the justice principle distinctly encapsulates the ethical consideration of fair participant selection.
