A photo of Ethologist John B. Calhoun in the middle of his infamous "Rat Utopia" Experiment. In the early 1960's, Calhoun would gain fame across the world for the publication of his "Behavioral Sink" theory. A Behavioral Sink claims that when overcrowding occurs there will be an eventual collapse of social behavior and norms as the existence of living in cramped conditions with no means of escape shall drive people into insanity due to their environment. Calhoun's Rat Utopia experiments would test this theory with his stuffing of enclosed spaces were rats were given an unlimited amount of food and water while not taking any action to cull population growth. Within a year the explosion of the rat population had lead to a disturbing collapse of social behavior such as mass miscarriages, rampant infantcide, division into groups of Alphas and Betas with a hierarchy of dominance, the formation of cliques centered around feeding drops, cannibalism, and sexual deviation.
Calhoun's publication of his findings in 1963 would promote mass hysteria over fears of overcrowding and Malthusian degradation of the Earth with Rat Utopias being used by various groups for their own ideological means. White Supremacists and Black Fascists tried to claim that Behavioral Sinks would occur with the mixing of races. Fascist nations claimed that Behavioral Sinks were the end result of democracy without populations having a common cause or ideology to unite behind. Capitalists and Democrats claimed that Behavioral Sinks would occur when a dense population was no longer given free will, choice, or competition. Communists claimed that Behavior Sinks would occur when humans no longer had a purpose that would be fulfilled with labor.
Over the course of the 1970's, the scientific community would turn against Calhoun's theories due to a growing criticism surrounding the variables of the experiment, the differences between mice and human physiology, the existence of complex human ideals and beliefs absent in mice, and the lack of any real-world examples of events close to a Behavioral Sink despite increasing urbanization and the growing density of such cities. By 1980, "Calhounism" had been relegated to a fringe of sociology, though in the minds of the public it was still a very real threat, one that would be commonly observed in the realm of science fiction, most famously cyberpunk and space opera genres.
John Calhoun would see a posthumous vindication of his theory in the 21st century due to the operations of the Bantustans. Life within the Bantustans with its hellish and chaotic society and complete lack of standard morals and ethics would present an image similar to a Behavioral Sink, leading many to believe that South Africa's draconian system had given birth to the first Human Behavioral Sink. This would give a new rise in popularity to Calhoun's studies and experiments with further projects and experiments being funded by universities in the West and Post-Fascist sphere to confirm the possible extent of Behavioral Sink. By 2021, "Neo-Calhounism" is an accepted and legitimate branch of sociology with Neo-Calhounists diverting away from Calhoun with an increased emphasis on societal isolation, stimulation depreviation, and resource deprivation instead of overcrowding, with many Neo-Calhounists claiming that the Islamic State of Arabia was the first Human Behavioral Sink. Another popular belief is that Syria is on its way to becoming another Behavioral Sink which it will reach in the next one or two decades if Turkish occupation and control continues.
Nearly 60 years after the conclusion of his Rat Utopia experiments at NIMH, John B. Calhoun has for better or worse left a great mark upon the scientific community. While a vocal community of Sociologists and Ethologists claim that Behavioral Sinks and Calhounism are a faux scientific practice reliant upon forced artificial circumstances with no natural behavioral sinks possible, more within their fields along with the general public accept it as a true scientific practice, one of many possible futures for humanity. No matter what one believes, it is a fact that the Behavioral Sink as an idea is for the near future here to stay.
