Population growth in the 1970s was swelling, and films such as Soylent Green tapped into growing fears of overpopulation and urban violence. “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. 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. The idea was to see how rodent populations. ![]() These particular experiments were done with mice and rats. Mice born into the chaos couldn’t form normal social bonds or engage in complex social behaviors such as courtship, mating, and pup-rearing. As promised here is my video on the Mouse Utopia Experiments by John B. 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. 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. John Calhoun’s colony was a mouse utopiaa giant pen with everything a mouse could ever desire: plenty of food and water, a perfect climate, and reams of paper to make cozy nests. The results, laid bare at his feet, had taken years to play out. Explore scientist John Calhoun’s mouse utopia and what it can tell us about the ways we impose lessons for society onto lab experiments. Calhoun conducted a series of experiments infamously known as the mouse. Interestingly, even when the population was well under 1/4 of the. Then, the population began to increase, doubling every 55 days. For the first 104 days, the mice explored their new habitat, marked their territory, and began nesting. In the 1960s, an ethologist by the name of John B. To begin the experiment, Calhoun introduced four pairs of healthy mice into the enclosure. 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. Utopia From the Greek word ou-topos, meaning no place, or nowhere.
