15 Most Disturbing Experiments in Human History

10. Stateville Penitentiary Malaria Study

During the Second World War, researchers enlisted the inmates at Stateville Penitentiary in Illinois. Not only was the prison population infected with malaria, prisoners were enlisted at every level of the experiment, including, “secretaries and technicians, recording data on one another, administering malarious mosquito bites and experimental drugs to one another, and helping decide who was admitted to the project and who became eligible for early parole as a result of his participation.”
