Ethical standards change from era to era. One notoriously unethical case was a study of syphilis conducted in Tuskegee, Alabama, from 1932 to 1972. In this study, African American males were told that they were receiving treatment for syphilis, but in fact, they were not. The researchers’ hidden goal was to study the long-term effects of the disease. Use the Internet to learn about the history of the Tuskegee syphilis study.
