A Hippocratic Oath for scientists is an oath similar to the Hippocratic Oath for medical professionals, adapted for scientists. Multiple varieties of such an oath have been proposed. Joseph Rotblat has suggested that an oath would help make new scientists aware of their social and moral responsibilities; opponents, however, have pointed to the "very serious risks for the scientific community" posed by an oath, particularly the possibility that it might be used to shut down certain avenues of research, such as stem cells.
The idea of an oath has been proposed by various prominent members of the scientific community, including Karl Popper, Joseph Rotblat and John Sulston. Research by the American Association for the Advancement of Science (AAAS) identified sixteen different oaths for scientists or engineers proposed during the 20th century, most after 1970.
Popper, Rotblat and Sulston were all primarily concerned with the ethical implications of scientific advances, in particular for Popper and Rotblat the development of the atomic bomb, and believed that scientist, like medics, should have an oath that compelled them to "first do no harm". Popper said: "Formerly the pure scientist or the or scholar had only one responsibility beyond those which everybody has; that is, to search for the truth. … This happy situation belongs to the past." Rotblat similarly stated: "Scientists can no longer claim that their work has nothing to do with the welfare of the individual or with state policies." He also attacked the attitude that a scientists only obligation is to make their results known, the use made of these results being the public's business, saying: "This amoral attitude is in my opinion actually immoral, because it eschews personal responsibility for the likely consequences of one's actions." Sulston was more concerned with rising public distrust of scientists and conflicts of interest brought about by the exploitation of research for profit. The started intention of his oath was "both to require qualified scientists to cause no harm and to be wholly truthful in their public pronouncements, and also to protect them from discrimination by employers who might prefer them to be economical with the truth."
