The story is about a old experiment happened in India in 1936. The experiment mentioned by the 1985 Nobel Peace Prize winner, Dr. Bernard Lown (1921-2021) in his book "The lost Art of Healing" and Dennis Coon in his book "Essentials of Psychology: Exploration and Application", which is a psychology textbook.
At that time, there was no experimental policy to protect human rights, so the experiment was at least possible. The subject of the experiment was a death row prisoner. He was given the opportunity to choose between dying due to excessive blood loss and hanging. This death row chose the former. This is the process of obtaining the experimental subjects. During the experiment, the death row was tied to the bed and blindfolded. The experimental scientist convinced the death row prisoner that the water dripping next to him was actually his own blood, and the death row prisoner could not see nature and could not verify it. The result of the experiment is that after a period of time, the subject really died.
The discussion can be extended to the result of Placebo,Voodoo death and if a person can scare to death.
