![]() ![]() It may be hard to clearly identify that cut-off, even though I'll try to make it explicit. Some of what I've seen in summaries seems clearly wrong, and I'll speculate beyond what the original researcher concluded. I would recommend that anyone who finds this theme as interesting as I do doesn't take my summary and conclusions as accurate, reviewing his take as well. I'll add links to two separate research papers by him, and one multiple-part video interview. If I'm remembering correctly Calhoun anticipated a relatively high population would develop relatively quickly, about as fast as normal breeding timing allowed for, and the results didn't match that. The idea was to set up rat or mice "utopias," isolated living conditions where they had ample food, shelter, safety, and separated living areas to see what the forms or stages of their breeding and behavior would be, as their population naturally increased. The "Universe 25" part relates to one experiment trial, obviously enough the 25th in a series. ![]() links to modern trends, especially related to social media trends and groups overview of the experiments (focusing mainly on one set of findings)ĥ. Then on to comments about how I see the mice and rat findings relating to current social trends, which play out in the most obvious fashion in social media use patterns and social groups.ġ. I'll pass on a short summary of what I see as the overview, then cite a summary I ran across that offers a somewhat abbreviated and highly interpreted version, then comments on what doesn't seem right in that. There's a lot to get through, and I have a number of comments on how I see it potentially relating to what we experience today, so I'll need to keep this moving. I've just ran across a really interesting summary of some social structure oriented experiments on mice by a researcher in the late 60s through the 70s, John Calhoun's rat and mice experiments related to the effects of overpopulation. Overcrowding is a killer.This is the third post in a row branching off the subject of tea, which I will get back to. Video of the whole experiment at the bottom. This is pretty damn interesting and scary at the same time. We are currently witnessing direct parallels in today’s society.weak, feminized men with little to no skills and no protection instincts, and overly agitated and aggressive females with no maternal instincts. John Calhoun repeated the same experiment 25 more times, and each time the result was the same.Ĭalhoun's scientific work has been used as a model for interpreting social collapse, and his research serves as a focal point for the study of urban sociology. By 1973, he had killed the last mouse in the Universe 25. Two years after the start of the experiment, the last baby of the colony was born. Among the endangered mice, homosexuality was observed and, at the same time, cannibalism increased, despite the fact that there was plenty of food. ![]() As time went on, juvenile mortality reached 100% and reproduction reached zero. At one point, "beautiful males" and "isolated females" made up the majority of the population.Īccording to Calhoun, the death phase consisted of two stages: the "first death" and "second death." The former was characterized by the loss of purpose in life beyond mere existence - no desire to mate, raise young or establish a role within society. They refused to mate with the females or to "fight" for their space. Then, a new class of male rodents appeared, the so-called "beautiful mice". There was a low birth rate and, at the same time, an increase in mortality in younger rodents. As time went on, the females showed more and more aggressive behavior, isolation elements and lack of reproductive mood. As a result, the females did not protect themselves and in turn became aggressive towards their young. The larger rodents began to attack the group, with the result that many males begin to "collapse" psychologically. When the number of rodents reached 600, a hierarchy was formed between them and then the so-called "wretches" appeared. However, after 315 days their reproduction began to decrease significantly. In the beginning, he placed four pairs of mice that in a short time began to reproduce, resulting in their population growing rapidly. More specifically, Calhoun built the so-called "Paradise of Mice", a specially designed space where rodents had Abundance of food and water, as well as a large living space. The idea of "Universe 25" Came from the American scientist John Calhoun, who created an "ideal world" in which hundreds of mice would live and reproduce. The "Universe 25" experiment is one of the most terrifying experiments in the history of science, which, through the behavior of a colony of mice, is an attempt by scientists to explain human societies. ![]()
