Have you ever sat down for a class on psychology? How about social psychology, in particular? Have you heard about the dreaded experiments, such as the Stanford Prison experiment, that were conducted for the sake of understanding the human mind better? Check out some of the most disturbing experiments in the 20th century.
Johnson's experiment involved telling orphans whether their speech patterns were good or not. Those who were told that they were terrible later developed problems with their speech behavior.
The United States used prisoners to test the effects of anti-malaria and malaria during World War 2.
The Nazis conducted a lot of horrible experiments that didn't have any scientific value whatsoever, including the hypothermia experiment in which a hundred people died after being submerged in freezing waters and then immediately getting hot water on them.
Stanley Milgram's experiment showed how people were willing to hurt other people as long as they were told by others they perceived as either powerful or an expert in the matter.
Dogs who were repeatedly electrocuted no longer wanted to leave the boxes even when they no longer had to face electrocution.
Harry Harlow experimented with baby rhesus monkeys by isolating them with fake, inanimate mothers. Those with comforting "cloth mothers" grew up better than those fearful, malnourished monkeys who had uncomfortable "wired mothers."
This study made students realize how it was to be black at the time of Martin Luther King. Those with blue eyes were praised and sent to the front of the class, while those with brown eyes were deemed as less intelligent, sent to the back, and wore collars. The setup was then switched and helped students understand how it was to be the one to face discrimination.
Philip Zimbardo's experiment showed how even six mere days could turn otherwise normal people into horrible, terrifying guards even if it was just roleplay. Likewise, the students roleplaying as prisoners experienced fear and started becoming rebellious just because of the experiment.
