In 1974, the United States Congress asked a question prompting a national conversation about ethics: which ethical principles should govern research involving human participants? To embark on an answer, Congress passed the National Research Act, and charged this task to the newly established National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research. The Commission's mandate was modest however, the results were anything but. The outcome was "The Belmont Report:" a trio of principles -- respect for persons, beneficence, and justice -- serving as an ethical compass for scientists, researchers, and institutional review boards (IRBs). Almost 50 years later, the utility, legacy, and ingenuity of "The Belmont Report" continues to be both admired and challenged. Critics argue that Belmont is not fit for the 21st century, while supporters praise "Belmont" for its enduring wisdom. The goal of this paper is to equip IRB practitioners with the tools necessary to maximally interpret "The Belmont Report" and meaningfully engage in ethical analysis that reconsiders outmoded legacy thinking and fixed decision-making. Through historical and contextual reflection, this paper describes how IRB practitioners can contemporize review of ethical human research using their moral imagination - a skill found at the intersection of creativity, deliberation, and empathy.
