We have invited twelve guests. They are told that our "research company" has been entrusted by the Ministry of Justice to carry out an experiment during which we are going to test an innovative method of corporal punishment on real inmates. The group of twelve persons may terminate the execution of the punishment by a majority of votes. That is seven persons can terminate the punishment by pushing a red button. Since the pain endurance level varies by person, this is how we can assure that everyone gets their deserved punishment "according to expert proposals". Will they help the poor girls by pressing the button early? Or will they enjoy their pain? How sympathetic are our guests with the "convicts"? Better see yourself!
