Why is the use of prisoners in research a concern under the Belmont principle of Justice?

The Belmont principle of Justice emphasizes fairness in research subjects' selection and the obligation to avoid exploiting vulnerable populations. The concern regarding the use of prisoners in research arises because any research involving them should not solely benefit society at large without giving them the opportunity to experience direct benefits. This principle advocates for equity, ensuring that specific groups, particularly those who may be marginalized or coerced into participating, do not bear the burdens of research without the opportunity for corresponding advantages.

In the case of prisoners, any study conducted should take into account the unique position they occupy. Research that only benefits the larger society while not addressing or ensuring benefits for the prisoners themselves raises ethical issues related to exploitation and inequality. By focusing on a fair distribution of the risks and benefits of research, the principle of Justice aims to protect these individuals from being used merely as means to an end without consideration for their wellbeing or contributions.
