in 1932, the US public health service began studying the effects of untreated syphilis in poor, African American males. The researchers wanted to better understand the progression of the disease, (since there was no “real” cure at the time) until the participants had died. The study lasted 40 years, the researchers made a series of abysmal ethical decisions:
i) The men were told that they were being treated
ii) The men who did not have syphilis-and then contracted it-were not told that they had the disease
iii) The men never received any beneficial treatment
