Population growth in the 1970s was swelling, and films such as Soylent Green tapped into growing fears of overpopulation and urban violence. Calhoun after a series of experiments about overcrowding in rodents. on the rat experiment. It is popular among groups within the manosphere due to some of its results reinforcing their narratives over societal behaviors. London) said that the appearance of Dr Calhouns mice resulting from the colour coding he used might affect. Behavioral sink (also known as the Mouse Utopia Experiments) is a hypothesis proposed by ethologist John B. “There’s no recovery, and that’s what was so shocking to ,” says Ramsden.Ĭalhoun wasn’t shy about anthropomorphizing his findings, binning rodents into categories such as “juvenile delinquents” and “social dropouts,” and others seized on these human parallels. Professor R A Weale (Institute of Ophthalmology. Effectively, says Ramsden, they became “trapped in an infantile state of early development,” even when removed from Universe 25 and introduced to “normal” mice. Instead of interacting with their peers, males compulsively groomed themselves females stopped getting pregnant. In his early experiments in the outdoor pens, Calhoun had witnessed a creative act by his rats that he likened to the discovery of the wheel by man: when building a new burrow they did not simply dig out the dirt as they went, as any normal rat would do, instead they packed it into a large ball which they then rolled out (Calhoun 1973b). Mice born into the chaos couldn’t form normal social bonds or engage in complex social behaviors such as courtship, mating, and pup-rearing. This iteration, dubbed Universe 25, was the first crowding experiment he ran to completion.Įventually Universe 25 took another disturbing turn. The only scarce resource in this microcosm was physical space, and Calhoun suspected that it was only a matter of time before this caused trouble in paradise.Ĭalhoun had been running similar experiments with rodents for decades but had always had to end them prematurely, ironically because of laboratory space constraints, says Edmund Ramsden, a science historian at Queen Mary University of London. ![]() A message from the past on how societies form around abundance. The shocking 1972 UNIVERSE-25 MOUSE UTOPIA experiment few have ever heard about. The centrally planned utopia, this is what happened. In 1968, Calhoun had started the experiment by introducing four mouse couples into a specially designed pen-a veritable rodent Garden of Eden-with numerous “apartments,” abundant nesting supplies, and unlimited food and water. More experiments on UNIVERSE 25 an RAT UTOPIA from 1973. The results, laid bare at his feet, had taken years to play out. Calhoun wasn’t the survivor of a natural disaster or nuclear meltdown rather, he was a researcher at the National Institute of Mental Health conducting an experiment into the effects of overcrowding on mouse behavior.
