Every research project that involves humans should balance harms and benefits.
When considering any research project, the potential net benefit should outweigh the potential net harm. This is in line with the universally recognized ethical principles of beneficence (doing good) and non-maleficence (not doing harm). These two principles stem from the belief that human beings have inherent dignity, which was formalized in the UN Declaration of Human Rights (1). In biomedical research, harms will almost inevitably be experienced alongside benefits. That’s why it’s important to carefully assess how important the benefits are and under what cost. These dilemmas should always be communicated to research participants, to ensure fully informed consent.
A number of mid-20th century studies, such as the Tuskegee syphilis experiment, were conducted to examine the natural history of a disease by either deliberately exposing human subjects to damaging stimuli, or by not giving them effective treatment (2). These are some of the most prominent examples of disproportionate harm to benefit.
