👉 Andreas Human Experiments was a controversial psychological experiment conducted by Dr. Andreas H. K. Müller in the 1970s which involved forcing participants to inhale noxious gas through a nose clip while their brain activity was observed via electroencephalography, raising serious ethical questions about informed consent and participant well-being. The study claimed to have demonstrated "true" empathy but was later widely criticized for its cruel nature, leading to significant changes in research ethics and practices.
