👉 Represented human experiments often refer to research studies where human subjects were subjected to ethical concerns or mistreatment, such as the infamous Tuskegee Syphilis Study, which withheld treatment from African-American men to observe the natural progression of their disease; these experiments highlight significant lapses in informed consent, patient safety, and medical ethics. More recently, studies involving vulnerable populations or psychological manipulation, like those on MKUltra's LSD experiments or the Stanford Prison Experiment, have drawn scrutiny for raising questions about the ethical boundaries in conducting scientific research on humans.
