John B. Calhoun was an American ethologist and behavioral researcher known for his studies on population density and its effects on behavior. He claimed that the negative effects of overpopulation observed in rodents served as a dark model for the future of humanity. Calhoun coined the terms 'behavioral sink' to describe deviant behaviors in crowded conditions and 'beautiful ones' to refer to inactive individuals who withdrew from social interactions. His work gained global recognition and was influential in various fields, including studies for NASA and research on overcrowding in local jails.
