👉 One example of a spectacular human experiment was the Stanford Prison Experiment conducted by Philip Zimbardo in 1971, where college students were randomly assigned to roles of prisoners and guards, revealing extreme psychological effects that led to rapid dehumanization and abuse of power. Another notable instance is the Tuskegee Syphilis Study conducted between 1932 and 1972, which falsely misled Black men in Alabama about receiving free health care while they were monitored for syphilis progression, highlighting unethical scientific experimentation on human subjects.
