This study, typically called the "Tuskegee Experiment", a nickname it gained after it was plagued by scandal in 1972, was formally called The Study of Untreated Syphilis in the Negro Male.

It is because Black people understand that we have been, and remain targeted by the U.S. government, and all of its institutions.
