# John B. Calhoun

> John Bumpass Calhoun was an American ethologist and behavioral researcher noted for his studies of population density and its effects on behavior. He claimed that his observations of the bleak effects of overpopulation on rodents were a grim preview for the future of the human race. During his studies, Calhoun coined the terms "behavioral sink" to describe aberrant behaviors in overcrowded situations, and "beautiful ones" to characterize passive individuals who withdraw from all social interaction under extreme population density.
