👉 Manhattan Human Experiments, often referred to as MKUltra, were a series of secret mind control and psychological warfare projects conducted by the U.S. government during the Cold War with various psychiatric hospitals, prisons, and research facilities. These programs involved unethical practices like hypnosis, electric shocks, and drugs to test and develop mind-altering techniques that were later widely condemned as both morally reprehensible and scientifically flawed.
