Smithsonian Magazine, 2/26/15 updated 8/8/24:
What does utopia look like for mice and rats? According to a researcher who did most of his work in the 1950s through 1970s, it might include limitless food, multiple levels and secluded little condos. These were all part of John Calhoun’s experiments to study the effects of population density on behavior. But what looked like rodent paradises at first quickly spiraled into out-of-control overcrowding, eventual population collapse and seemingly sinister behavior patterns.
In other words, the mice were not nice.
I’m seeing a lot of parallels between the mice and homo sapiens lately.
Working with rats between 1958 and 1962, and with mice from 1968 to 1972, Calhoun set up experimental rodent enclosures at the National Institute of Mental Health’s Laboratory of Psychology. He hoped to learn more about how humans might behave in a crowded future. His first 24 attempts ended early due to constraints on laboratory space. But his 25th attempt at a utopian habitat, which began in 1968, would become a landmark psychological study. According to Gizmodo’s Esther Inglis-Arkell, Calhoun’s “Universe 25” started when the researcher dropped four female and four male mice into the enclosure.
By the 560th day, the population peaked with over 2,200 individuals scurrying around, waiting for food and sometimes erupting into open brawls. These mice spent most of their time in the presence of hundreds of other mice. When they became adults, those mice that managed to produce offspring were so stressed out that parenting became an afterthought.
So it’s like…if the “survive and thrive” instinct is challenged by harsher conditions, it maintains its place as a top priority. If the hardships are suspended or removed altogether the priorities change.
What I notice about The Left — and I would expect The Left would agree with all this — is:
1. They and their ideological compatriots command and control the dominant, prevailing narrative in physical locations where the population density is high.
2. Perhaps because of #1, they place greater weight on what people think of each other when they conclude certain things. You ask them “What is a woman?” and the very last thing that goes through their minds is what a woman is; they’re much more drawn to choosing the proper insult for you for daring to ask the question.
3. To The Left, this is not neglect of “truth” because they don’t accept the supposition that there is a unified, objective truth. Their understanding of truth is a social thing. We accept a common “truth” to show we’re in a common tribe and can be friends.
4. Because they live in a world where we each choose our own truth, cause and effect relationships are up for debate. Experimentation does not confirm or refute theories; experiments, rather, bring credit or discredit upon themselves. The theory determines what the experiments have to do to be valid. Example: Socialism works. Anytime it doesn’t, it wasn’t implemented the right way. The wrong people were in charge.
5. The failings of human nature do not confound these theories because human nature simply isn’t a factor. Get rid of all the guns, there won’t be any violence. Equalize income and wealth, there won’t be any crime. If there’s no necessity to go to work, people will concentrate all their time and resources on mind-expanding, worthwhile, artistic things.
Where The Left would disagree with me, I expect, is in this correlation I draw between high-population-density, inner-urban, blue-state living and the “Beautiful Mice” experiment that removes significant difficulties from the effort to survive. This is an easy call. Blue state thinkers and voters don’t imagine themselves to have it all that easy. They think they’ve got it tough.
And with high crime, crumbling infrastructure and artificially inflated prices of goods and services, in a way they’re right.
