Tuskegee syphilis experiment

It was a clinical study conducted between 1932 and 1972 in Tuskegee, Alabama, by the U.S. Public Health Service. Investigators recruited 399 impoverished African-American sharecroppers with syphilis for research related to the natural progression of the untreated disease, in hopes of justifying treatment programs for blacks.

The 40-year study was controversial for reasons related to ethical standards, primarily because researchers failed to treat patients appropriately after the 1940s validation of penicillin as an effective cure for the disease.

By 1947 penicillin had become the standard treatment for syphilis. Choices might have included treating all syphilitic subjects and closing the study, or splitting off a control group for testing with penicillin. Instead, the Tuskegee scientists continued the study, withholding penicillin and information about it from the patients. In addition, scientists prevented participants from accessing syphilis treatment programs available to others in the area. The study continued, under numerous supervisors, until 1972, when a leak to the press resulted in its termination. Victims included numerous men who died of syphilis, wives who contracted the disease, and children born with congenital syphilis.

perception post

"Doubt is the key to knowledge". To what extent is this ture in perception?

Opinion: I believe that this is true in perception because when you have doubts you start to research more or ask on the topic in which you have a doubt. Then you gain more knoweldge on more things. This knowledge help you perceive things in many different ways. Perceiving things in different ways helps you be more emotional intelligent and helps you gain knowledge in your personal life.

support 1: For example if you hate Jews because you're a muslim but you have doubts on why muslism and jews hate each other you can go research. Then when you have researched you have gained more knowledge on the problem and can perceive things differently or at least see things from both points of view.

support 2: Doubting theories in science or psychology may lead you to research and find out new things. Then when you have more knowledge in the topic you can probably talk about it and explain it to other people. Then you can perceive things differently after you have more knowledge on the topic.

Support 3: For example if you doubt that true friendship exists you can start getting along with everyone to find out. When you have found out, you gained knowledge by getting along with everyone and by learning something new from each of your friends.
