The Monster Study
In this study, conducted in 1939, 22 orphaned children, 10 with stutters, were separated equally into two groups: one with a speech therapist who conducted "positive" therapy by praising the children’s progress and fluency of speech; the other with a speech therapist who openly chastised the children for the slightest mistake. The results showed that the children who had received negative responses were badly affected in terms of their psychological health. Yet more bad news was to come as it was later revealed that some of the children who had previously been unaffected developed speech problems following the experiment. In 2007, six of the orphan children were awarded $925, 000 in compensation for emotional damage that the six-month-study had left them with.
The CIA performed many unethical experiments into mind control and psychology under the banner of project MK-ULTRA during the 50s and 60s. Theodore Kaczynski, otherwise known as the Unabomber, is reported to have been a test subject in the CIA's disturbing experiments, which may have contributed to his mental instability. In another case, the administration of LSD to US Army biological weapons expert Frank Olson is thought to have sparked a crisis of conscience, inspiring him to tell the world about his research. Instead, Olson is said to have committed suicide, jumping from a thirteenth-story hotel room window, although there is strong evidence that he was murdered. This doesn't even touch on the long-term psychological damage other test subjects are likely to have suffered.
