Scientists are testing the idea that the stress of modern city life is a breeding ground for psychosis.
In 1965, health authorities in Camberwell, a bustling quarter of London's southward sprawl, began an unusual tally. They started to keep case records for every person in the area who was diagnosed with schizophrenia, depression, bipolar disorder or any other psychiatric condition. Decades later, when psychiatrists looked...
Yet the results of his study, published last year in Nature (F. Lederbogen et al. Nature 474, 498501; 2011), clearly showed that people who grow up in cities process negative emotions such as stress differently from those who move to the city as adults. His team scanned the brains of 55 healthy volunteers as they carried out arithmetic tasks under a constant bombardment of negative social feedback. We'd always let them know through headphones that we thought they were failing, or at least not doing as well as other subjects we'd had in the scanner, says Meyer-Lindenberg. In one set of experiments we let them see our impatient faces on computer screens.
This social stress activated two brain areas but the pattern depended on the volunteers' histories of urban living. The amygdala, which processes emotion, showed much greater activity in people who were currently living in a city. And the cingulate cortex, which helps to regulate the amygdala and processes negative emotion, responded more strongly in those brought up in large cities than in those brought up in the countryside, irrespective of where they lived now. Meyer-Lindenberg thinks that this over-responsiveness to stress could make city-dwellers more prone to psychiatric conditions such as schizophrenia and his results chime with the idea that stress in childhood or adolescence can have a lasting effect on the brain's development and increase susceptibility to psychiatric disease...

Nothing new, it’s been observed for centuries.
...and what political ideology mostly resides within cities ?
Causation makes correlation.
I try keeping my brain locked down better than Obama’s history. Sometimes things do slip, but it’s every now and then, and I’m easily able to regulate the flow of emotions out.
An extremely easy fix would be going away from NYC, while keeping constant contact with friends.
(if I need a /sarc tag for that...)
THOSE HORRIBLE BAD EVIL 1%EERS IN THERE GILDID MANSHUNS AND FANSY PENT HOUSIS !!!!!!!! .......RITE????????????

solution: urban voters only allowed a half vote - we could call it the ‘crazy differential’
The biggest problem with large cities here in the U.S. is they are run by DemocRATS. From what I understand, large cities in the Orient in places such as Singapore, Japan and Malaysia are modern wonders to behold. Of course, they don’t have Greenie whack jobs and RAT politicians to contend with. My cousin John lived in Singapore. He said the cities here in the U.S. are 3rd world compared to the Orient.
I remember a NOVA presentation on PBS (when I was a teenager) based on crowded cities and their effect on people.
They used rats in gradually over-populated cages—stress producing “environment”—they kept adding rats.
Eventually, the rats turned to extreme violence and cannibalism; can’t help but think of our larger cities now; filled with rats that eat the faces off the other rats.
Scientists are testing the idea that the stress of modern city life is a breeding ground for psychosis.
Have you ever met anyone from NYC that didn’t have issues?
It isn’t exactly news that urban societies are associated with higher rates of mental disorders.
Ah yes, the Universe 25 experiment.
There was a comic book series in the 1980s called Mister X that touched on this. Mister X was not a superhero, he was a brilliant and eccentric architect. He designed a city where every building, shape and line reinforced positive emotions and healthy psychological well being. He did not see the city built, but had a nervous breakdown and spent years in a mental hospital.
When he was released, he found that the city had been built in his absence. But not exactly the way he designed it. This city had the lines and shapes subtly changed. In stead of promoting happiness and positiveness, it reinforced psychosis, suicide, and mental illness. All of its residents were slowly and deliberately being driven insane.
The character spends the city looking for the people who built the city, and the secret of why it was changed.
Ah, so in other words, that has the very same psychosis causing effect as approvingly telling them 24/7 dat dey BEEEE somebody and aren't to blame for their own failed socio-economic station in life. Because the first version these researchers tested has almost NOTHING to do with the price of tea in China.
Interesting results. Probably done by a liberal prof.
But what would be really interesting to know is whether the liberal prof thinks that the liberal sustainable development plan to herd everyone out of the suburbs and into big buildings in cities so that the animals can run free (or whatever their reasoning is) is a good idea.
I can tell you that country people are better adjusted and far less silly than city people. And I’ve been in both places.

I have met very few people from any major city I would not consider to be more than a bubble off of level...
It's the ones that you can't even see the bubble that scare the hell out of me.
Think: DETROIT. Enough said.
Rats running a nut house sounds like a natural enviornment for cities.
I went to great expense to raise my family in a country setting because I did not want the boys raised in the social stress (insanity) of a city. It’s hard enough growing up and becoming a man without playing human predator and prey every day of your young life.
A city child’s disconnect with his own self and nature is severe. We participated in a summer program for city kids and took a boy from Harlem into our house. His amazement and love of the country’s grew but first he had to deal with the issue of being with his own senses, mind and body. He was driven in the city in reaction to the city and never had the experience of driving himself. One of the things he was most overwhelmed by was the smell of the country versus the smell of Harlem. Sometimes he’d just sit out back, listen to nature and sniff. LOL
The main object of Agenda 21 is to force everyone out of nature and into packed, highly controlled cities. Liberals seem to have a radar for all that is destructive of human life and well being.
Tests in the 1950’s show what happens with rat populations.
They are normal, and exhibit normal behavior UNTIL the population is raised past a certain critical threshhold, either by birth, or addition of more rats to the enclosure.
ALL KINDS of abnormal behavior then start up.
Infanticide, extreme aggression, homosexuality, weird dietary behavior, things that can best be labelled “Rat OCD’s”
I have the Sci-Am reprints, some of them may even be available online.
Detroit is rapidly turning back into farmland. Not kidding.
Thanks. Great article, excellent summation. To quote... “the results were ALWAYS the same...”
And it is important to pay attention to the fact that it WAS NOT a lack of resources like housing or food.
In fact, they had the equivalent of Public Nesting and rat EBT cards!!
I’d toss in a sarcasm tag, but it’s just too damn scary to get one!

Imagine a group of humans, indeterminate in number, confined in a place of fixed dimensions, wanting for nothing. They have plenty to eat, plenty of water, plenty of places to live, and only the dimmest sort of apprehension of a larger world. They might even think of “the outside” as a kind of malicious fiction perpetrated by malcontents. It’s a circumstance not unlike the one “sustainable development” is supposed to create for us. Also, not unlike the universes of John Calhoun’s rats.
Laboratory animals often substitute for humans in tests of hazardous environmental factors. Their use in the study of cancer-causing and toxic chemicals is almost universally accepted. Their responses can, and do, give insight into human behavioral psychology. They are useful as models for humans precisely because their repertoire of behaviors is simpler than that of men and women, and so it is easier for scientists to control the variables. This also gives us the latitude to say, when we don’t like the results of such tests, that humans and rats are different.
And that is why, when ecologist John B. Calhoun passed from the scene in September of 1995, The New York Times noted in his obituary that his work had often met with “studied disregard.” He had spent his life studying the behavior of enclosed rodents.
The term “enclosure” has a specific meaning different from crowding. (See an earlier article, First Principles, for a more complete explanation.) Calhoun’s animals were not just thrown together in a cage. They grew up in confinement, generation after generation, without the ability to imagine an escape.
The research began at Johns Hopkins in 1946 and continued through the ‘60s, when Calhoun, then a research psychologist at the National Institute of Mental Health, published a report of the work in Scientific American. What fascinated students and readers of this research, then and now, is that the rats in Calhoun’s experiments developed social pathologies similar to the behavior of humans trapped in cities. Among the males, behavioral disturbances included sexual deviation and cannibalism. Even the most normal males in the group occasionally went berserk, attacking less dominant males, juveniles and females. Failures of reproductive function in the females - the rat equivalence of neglect, abuse and endangerment - were so severe that the colonies would have died out eventually, had they been permitted to continue.
Before going on, it is especially important to be clear on this point: None of Calhoun’s experiments began with throngs. All of his populations started out small, with superabundant resources, and grew after many generations into a state of crowding that approximated 80% of carrying capacity. That is to say, 80% of the nesting boxes in the enclosures were occupied at the peak population.
Appropriately, Calhoun called his confinements “universes,” since the animals inside them knew nothing of an outside. The rats of the early days required complete rooms as universes. This, and the fact that crazy rats are notoriously difficult to care for, is what must have shifted Calhoun’s affections to mice in later experiments. Full details of Universe 25 appear in a 1970 paper titled The Explosive Growth and Demise of a Mouse Population.
A few salient points from the paper:
* The mice in Universe 25 developed a social system with a fixed number of places. In nature, the excess population emigrates to what, in human terms, would be a frontier. But in Calhoun’s rodent Shangri-La, the possibility of emigration is excluded because ecologists define emigration as a “mortality factor.” It is therefore not utopian. Rejected males gathered in “pools” on the floor of the universe, where they fought frequently. Females not accepted in the social structure withdrew to less-preferred nesting boxes in the higher reaches of the universe.
* Dealing with large numbers of maturing competitors overtaxed the territorial males. In response to the invasion of nesting sites by interlopers, females became aggressive, taking over some of the defensive duties of the males. This aggression generalized to their young. A pronounced rise in preweaning mortality marked the end of social structure in Universe 25.
* With the end of successful reproductive activity, the population plunged exponentially and the age distribution shifted into senescence. The remaining individuals of reproductive age had, by this time, lost interest in courting. Calhoun dubbed the males “beautiful ones” for their obsessive grooming. It had been expected that the population would rebound after declining to a few remnant groups. It did not. What’s more, healthy young individuals from Universe 25, transplanted to an empty universe of their own, failed to develop a social structure or engage in reproductive activity.
It seems clear that, for rodents at least, the absence of frontiers leads to what Calhoun calls “death of the spirit.” This first death leads to species extinction, the “second death.” A study of the headlines over the last thirty years or so yields some interesting parallels with the human condition, but there’s no room for that here.
A final observation: Calhoun’s work remains unfinished. His experiments could be extended to include a frontier, or an unlimited succession of frontiers, by linking a populated universe with a string of empty ones. The path to each new universe would have to be made arduous, say by a maze, or by an electrical grid designed to deliver painful but non-fatal shocks. Even more interesting, for computational types, would be the creation of digital life forms complex enough to check out frontier theory analytically.
Those of you readers interested in such things, do try. One might say your life depends on it.
I should note Calhouns original work was entitled “Population Density and Social Pathology” Scientific American, March, 1962, pps 139-148
He passed, and an Obituary was posted about Sept, 1995
Not sure if his work continues.
Heh, I suppose so. I moved to the city when I was 38 years old and processed my stress by moving right back out twenty years later. It worked, too.
Mental illness is caused by too many people. Hmmmmm.....how do we reduce the population? Do you see where this is going? The liberals must live as long as possible because, well, they’re just smarter than everyone else. And their quality of life must be improved by having less traffic and fewer people at their beaches. They’re filthy, stinking eugenics believers.
