In the 1960's, a biologist, John Calhoun, created a large cage for mice that would provide them with plenty of living space, and which was isolated from the outside world so that they didn't have to suffer from predators or other mice.

Only healthy mice were allowed into the cage, so none of the mice were sickly, retarded, or mentally ill. He provided them with plenty of food and water so that they didn't need to work for, or compete for, food or water.

The cage was kept in a room that provided them with a pleasant climate so that they didn't have to suffer from bad weather. The mice had freedom to do whatever they pleased.

They could spend their time enjoying themselves, as if they were in a mouse heaven, like those in the drawing to the right.

The experiment could be summarized as initially providing the mice with a wonderful life, but since they reproduced in large quantities, and since the cage had a limited size, they eventually reached a population density that was larger than what they had evolved for.

Most creatures have an emotion that causes them to want a certain amount of territory for themselves, and when other animals are in their territory, that emotion is stimulated, which creates an unpleasant emotional feeling. That causes the creature to become upset or irritated with the intruder, and that causes him to either run away to a less crowded area, or try to chase away the intruder.

However, the mice could not move to a less crowded area because the cage had a fixed size, and they could not chase the intruders away because there was no place for them to go to. Therefore, their territorial emotion was constantly being stimulated.

None of our unpleasant emotions are supposed to be stimulated constantly. That territorial emotion should have been stimulated only momentarily once in a while. When an unpleasant emotion is stimulated, it creates what we could describe as stress, irritation, frustration, or misery.

An animal reacts to an unpleasant emotional feeling by doing something to stop it, but the mice could not do anything to stop that unpleasant emotion. Therefore, they were suffering constantly from the overcrowding, which affected their attitudes and behavior. They were in a situation that was similar to the people who have Prader-Willi syndrome, except that instead of being constantly irritated by hunger, they were constantly irritated by the overcrowding.

The result was that their behavior became increasingly abnormal. Eventually the male and female mice had trouble forming relationships, which caused their population to decrease. That should have solved the problem of overcrowding, but the baby mice were being raised among adults who had abnormal behavior. The adults were not proper role models so the baby mice did not learn "proper mouse culture". Instead, they picked up "neurotic mouse culture". They became adults who had trouble forming relationships and raising babies. Their population continued to decrease until all of them had died.

Some people believe that the experiment shows what might happen to the human race if we do not control our population. For example, the Smithsonian magazine published this article with the title:

sciencehistory.org posted this article with the subtitle:

The people who believe that the experiment is a possible prediction of our future are examples of people who have such a distorted view of humans and animals that they give us unrealistic analyses of news events, historical events, human behavior, and culture. They give us a distorted view of the experiment because they don't have the emotional ability to look critically at humans.

The "Mouse Utopia" experiment was not showing us what our future might become. Rather, a document about the experiment would be more accurate if the title was:

The 1960 Mouse Utopia Experiment
Provides an Understanding of Human History

We are at the stage at which the mice were experiencing constant and unpleasant emotional stimulation from overcrowding, and which had resulted in them developing abnormal behavior. However, human behavior is more complicated, and we are suffering from more than overcrowding, and this results in such a wide variety of abnormal behavior that it is difficult to notice the similarities between our behavior and that of the mice.

We are suffering from problems that the mice did not have, and could not suffer from, such as crime networks, human trafficking, noise, traffic congestion, pollution, telemarketers, and a mixture of races and cultures that ignore, fear, or hate one another.

Furthermore, the mice were never irritated by accusations of feminism, sexism, anti-Semitism, racism, climate change denial, homophobia, or Holocaust denial.

The mice were also one race, rather than a mixture of different races. Therefore, there were no white mice who had to listen to brown mice whine about white privilege, and there were no angry, Pakistani mice to give a speech at a university in which they boasted about being a hero:

Our abnormal environment is stimulating various unpleasant emotions more often than we were designed for, which causes us to be irritated more often than we were designed for. We are being irritated excessively, just like the mice. The excessive irritation interferes with our thoughts, decisions, goals, social activities, and treatment of other people. It is causing us to behave abnormally, just like it did for the minds.

The three main reactions of the mice was to:

It is impossible for us to know how our prehistoric ancestors behaved, so we cannot compare our behavior to theirs to determine what has changed. However, there are a lot of reasons to believe that people today are behaving in an abnormal manner, just like those mice. For example:

	1)	The volume of our voice. I have heard people from or in foreign nations complain that Americans speak at an excessively loud volume level, and I have even been told a few times to lower my volume level. Many of the people in Europe, Japan, and Asia speak at a noticeably lower volume level, and they are also less likely to have conversation in public, such as on trains. Why do so many Americans speak at a high volume level? Many foreigners assume it is because we are rude, impolite, or inconsiderate, but I think it is because many Americans are living in less crowded conditions. The human mouth and vocal cords were designed to speak at a certain volume level, and I think many Americans are speaking at that "normal" level because we are living in less crowded conditions. The people in Japan, Hong Kong, and Europe are living in such extremely overcrowded conditions that if they were to speak at a normal volume level, they would annoy one another. Their extreme population density has resulted in them reducing the volume of their voice in order to reduce the irritation of one another. They also avoid having conversations in public in order to avoid irritating one another. They are not quiet because they are more polite than the Americans. Rather, it is because they are behaving like a dog that has been beaten with a stick, and is hiding in a corner. Or, we could describe them as behaving like those mice who were hiding in the corners.
	2)	Relationships are deteriorating. The overcrowding caused the mice to want to get away from the other mice, which interfered with the desire and/or ability of the male and females to form relationships. Although feminists claim that men have been abusing women all throughout history, it is more sensible to believe that they were forming relationships as easily as all of the other animals, and that their relationships were more pleasant than they are today. The reason is because most of the reasons that married couples fight with each other today did not exist in prehistoric times. Today men and women have so much trouble forming relationships that very few of the relationships become a marriage, and many of the marriages end up in divorce. Some of the couples who remain together are actually miserable but are more afraid of a divorce than of remaining in a miserable marriage. The couples who have truly pleasant marriages seem to be an increasingly small percentage of the population. I also suspect that some of the people today who claim to be homosexual are actually frustrated heterosexuals who have gotten involved with a homosexual relationship because they are so lonely and frustrated. There are also some people who form close relationships with dogs, inflatable women, children, and sex robots. We should consider that they are doing that because they are having trouble finding a compatible spouse or friend. Although there are a lot of different ways to explain the problems that people today are having with relationships, such as the genetic degradation of the human race, but we should consider the possibility that our behavior is becoming abnormal for the same reason that the behavior of the mice became abnormal.. Specifically, that our social environment has become so unnatural that our unpleasant emotions are being stimulated excessively, which is causing us to be irritated much more often then we should be, and for longer periods of time, which in turn is causing us to develop abnormal attitudes and behavior. Furthermore, relationships between men and women are deteriorating because we are suffering from problems that neither the mice nor our prehistoric ancestors had to deal with: • Adults are preventing children from learning about sexual issues, so the boys are becoming men who are ignorant about, and have obnoxious obsessions with, sex and women's sexual organs. This is causing a lot of women to be irritated, and causing a lot of men to be frustrated. • We allow businesses to contaminate our culture with advertisements that stimulate men sexually. We also allow businesses to stimulate people excessively with wedding pornography, romance pornography, and baby pornography. All of the pornography is stimulating boys and girls to an excess, and giving them unrealistic expectations of life. For example, the wedding pornography is causing girls to develop obnoxious obsessions with weddings. Businesses are also stimulating people excessively with pornography about traveling to exotic locations; becoming wealthy enough to purchase yachts, mansions, and diamonds; and becoming famous and winning lots of trophies and awards. The extreme pornography is stimulating our emotions excessively. Even though many of those emotions are pleasant, we were not intended to be stimulated to such an extreme. It is resulting in children picking up unrealistic and idiotic expectations of marriage, sex, travel, material items, fame, babies, jewelry, tattoos, pets, and lots of other issues that businesses can profit from. • We allow media companies to produce television programs and movies that give children a distorted view of relationships and sexual behavior, such as when a television program shows two male doctors at a hospital who cannot resist having sex with one another in a closet at the hospital. Although there are certainly people who behave in that manner, the television programs are giving children a distorted view of what is "normal" human behavior. Many of the television programs and movies also deceive children into believing that women are almost as sexually aggressive and promiscuous as men. • We allow feminists to promote the accusation that men are sexist creatures who abuse women, and the theory that we are unisex creatures. The unisex theory encourages women to marry a man who is her "equal", rather than a man who can provide her with guidance and take care of her and her children. However, the only men who are equal to women are feminine men, or homosexuals. • We have a natural desire to compete with one another for status, but the difference between the wealthy and poor people is so extreme today that our emotions are stimulated excessively. This causes a lot of people, especially men, to become obsessed with comparing their wealth to that of other people, and struggling to get more wealth. It also causes a lot of people to whine about their low income, the high prices, or the high taxes, even if they have an above-average income. It also results in people showing off their wealth, which adds to the stimulation of the poor people, and can result in envy, anger, or low self-esteem. Some people become so obsessed with getting more wealth that they commit crimes to get more of it, and that causes them even more mental anguish because they will then forever worry about being exposed and arrested. The mice suffered only from overcrowding, so we ought to wonder what would have happened if they had also been suffering from some of the problems that modern humans suffer from. For example, imagine if the male mice were suffering from excessive sexual stimulation; the female mice were whining about sexism and suffering from excessive stimulation of baby pornography; and all of the mice were also suffering from telemarketers, extreme differences between wealthy and poor mice, noise, pollution, and traffic congestion. How would all of those problems have affected their behavior? When the overcrowding of the mice became so severe that the adults began behaving in an abnormal manners, their children were also stimulated excessively, and their children were raised by adults with abnormal behavior. This resulted in the children becoming adults with abnormal behavior. This problem seems to be occurring with human children today. For example, a lot of people today are so afraid of getting married that they either delay it by many years, or they live together without getting married. Many couples also delay having children. This could be interpreted as evidence that they are behaving like the young mice who had trouble forming relationships. Some teenagers are so confused about what to do with their life that they spend a few years traveling around the world, or trying different activities. We have expressions to describe this: find oneself and find yourself. We will never know if any of the prehistoric teenagers wasted some of their life in an attempt to "find themselves", but it is unlikely. The confusion of the modern teenagers is more likely to be due to the same reason that the young mice became adults who could not function properly in society. Specifically, modern children are being raised in an unnatural environment in which they are being stimulated excessively, and they are being raised by adults who have abnormal attitudes and behavior.
	3)	Excessive masturbation. Some of the mice reacted to the overcrowding by spending excessive amounts of time grooming themselves, and I think it was to bring some pleasure into their miserable life. This behavior can be seen with people, also. When we are unhappy, we tend to do something that brings us pleasure. We should consider the possibility that some people are grooming themselves excessively, just like some of the mice. For example, there are some people spending a lot of their time and resources on their hair, tattoos, cosmetic surgeries, body piercings, and fingernail decorations. Do those people truly enjoy those extreme grooming activities? Or are they doing it because they are miserable? There are also people who react to unhappiness by eating, and others react by shopping, having sex, taking drugs, watching television, trying to become the center of attention, playing with a pet dog or child, or struggling to win trophies.
	4)	Withdrawing from society. Some of the mice reacted to the overcrowding by trying to ignore the problem by hiding in a corner. Many people are doing something similar, but instead of hiding in corners, people ignore or ridicule the problems, and believe whatever they find more pleasant. This can be seen when we provide them with evidence that we were lied to about the 9/11 attack and the Holocaust, and that many of the influential people are pedophiles. They refuse to think about the evidence. They push it away, ridicule it, or ignore it, which is essentially the same as running away from it and hiding in a corner. Some people go even further and create a pleasant fantasy world for themselves. One of the most popular are the religious fantasies in which they imagine some type of supreme being is floating around in the clouds. They imagine themselves talking to that supreme being, and that he will protect them from danger. Other people withdraw into Harry Potter, Star War, or Avatar fantasy.

Our prehistoric, nomadic ancestors were living in an environment that they had evolved for, so their behavior would have been "normal". However, we cannot observe them, so we cannot see how they treated one another, or how they raised their children. We cannot listen to their voices, either, so we don't know the volume level that they spoke at.

When our ancestors settled into cities, they inadvertently put themselves into the mouse utopia experiment. The very first cities provided everybody with plenty of land and food, so the city would have resembled the mouse experiment at its beginning. The first few generations of people in those cities would have enjoyed living in them.

Today, however, most of our cities are so overcrowded that the people are living in the phase of the experiment at which the mice were developing abnormal behavior.

We are not fighting with each other as often as the mice were fighting with each other, but that is only because we are routinely suppressing our anger of government officials, business executives, our neighbors, and telemarketers. If humans had as little self-control as mice, we would be regularly getting into fights with one another, and causing a lot of deaths.

Even though we exert a lot of self-control over our anger, all of us occasionally lose our temper over issues that did not exist in prehistoric tribes. For example, all of us occasionally becomes irritated by other people when we are driving an automobile, and so many people have lost their temper that we have an expression for it: road rage.

Our modern societies are causing all of us to frequently be irritated by something. We are suffering from irritation much more often, and for longer periods of time, than we were designed for. This results in us constantly struggling to control our temper, pouting, and anger.

We have no idea how often prehistoric people became irritated with one another or with situations in their life, but it is impossible that they were irritated as often as we are because most of the irritations that we suffer from did not exist in prehistoric times.

We are being irritated more often, and for longer periods of time, then any of our ancestors, and we cannot ignore this. Excessive stimulation of unpleasant emotional feelings will have a detrimental effect on the attitudes and behavior of all animals because the unpleasant emotions evolved in animals in order to make them do something to eliminate the source of the irritation.

However, we cannot eliminate the sources of the modern irritations. This results in us doing something idiotic instead, such as distracting ourselves with something pleasurable, by taking drugs, by withdrawing into fantasies, or by becoming whiny, irritable, angry, envious, or sad.

Since human behavior is more complicated than mouse behavior, many of us behave in a manner that is significantly different from the mice, which makes it seem as if we are not similar to the mice. However, there are a lot of things that people are doing today that suggests that they are miserable, and they are struggling to either stop the misery, or counteract it with some pleasurable activity. Three examples of modern behavior that we should consider to be the result of our suffering:

	1)	The craving to travel. Our nomadic ancestors never had vacations. They worked every day of their lives. It is unlikely that any of them fantasized about having a vacation so that they could travel to an "exotic" area of the world. As discussed in the Jobs document, animals evolved to enjoy working. Animals have no desire for vacations, sick days, holidays, or weekends. Animals are inherently lazy, so when they have nothing to do, they do nothing, but when they are stimulated, they enjoy working. Humans have more curiosity than animals, and that can cause us to want a vacation simply to allow us to visit a different city or area of the world, but we should consider that one of the reasons that we want vacations and to travel outside of our city because we are in a similar miserable situation as the mice. Two reasons that our social environment is abnormal and causing us to to want to travel during a vacation are: a) Our cities are miserable. When an animal is unhappy with its living conditions, such as its lack of food, or the large number of predators, it will consider moving to another area. Humans inherited that characteristic. We refer to that attitude as: The grass is greener on the other side of the fence. When we are unhappy with our city or our lives, we are likely to assume that there is another city that is more enjoyable, and has better people. If we enjoyed the city and the people that we were living with, our desire to travel would decrease. We would continue to want to visit other cities and areas, but only to experience something different, not to escape from our misery. Unfortunately, we cannot design a city and culture that everybody is happy with because we have subtle differences in our intellectual and emotional characteristics. Therefore, in order to create a city that the people enjoy, we must restrict the immigrants to people who enjoy whatever culture we decided to create for the city, and we must also restrict reproduction to reduce the genetic diversity of each generation so that the people remain compatible. b) Children are picking up false concepts about vacations. Modern children are picking up idiotic attitudes towards vacations and traveling. One reason is the same as it was for the mice; specifically, the adults are behaving in an abnormal manner. For example, the adults who try to become the center of attention by boasting about their travels are inadvertently fooling children into believing that the people who travel are having a better life than those who do not. However, we have an additional problem that the mice did not have. Specifically, organizations that profit from promoting traveling. Those organizations are deceiving us into believing that there are certain areas of the world that are more "exotic" and "exciting" than wherever we are living right now, and that the only way we can fully enjoy life is to travel to those areas. When we have a vacation, it should be for a "sensible" reason, not because we have been deceived by people who want to be the center of attention, or by businesses that want to exploit us for profit. We dislike our cities and social environment, and that is causing us to remain inside our homes, or move to the suburbs, or go on vacationswant, but those are idiotic reactions. A more sensible reaction is to study human behavior and experiment with our cities and social environment so that we can provide ourselves with a city that we enjoy.
	2)	The craving for material wealth. People today are phenomenally wealthy compared to our ancestors, but most people are constantly whining that they don't have enough money, that prices are too high, their income is too low, and taxes are too high. Some people are going beyond whining about their shortage of wealth; they are looking for opportunities to commit crimes; trying to find a wealthy spouse; or they are trying to become wealthy from lotteries or gambling. There are lots of ways to explain why so few people are enjoying their wealth, such as the genetic degradation of the human mind during the past few thousand years, and the boasting about material items by the wealthy people. However, we should consider that one of the reasons people are whining about not having enough wealth is because our modern societies allow people to have extreme differences in wealth. There are some people who have gigantic mansions and private jets, and other people who have tiny apartments. These extreme differences are unnatural for us. We evolved to live among friends who don't have much of a difference in material wealth. Our modern environment is unnatural, and it is stimulating emotions of envy, competition, anger, and sadness. It makes us feel inferior, abused, and like slaves or peasants. The constant stimulation of unpleasant emotions has caused many people to come to the false conclusion that they are miserable because they don't have enough material wealth. In reality, they are suffering because we are living in an abnormal social environment, just like those mice. A person who is suffering from a lack of wealth cannot improve his life simply by getting more wealth. The reason is because he is not suffering from a lack of wealth. He is suffering because our culture is unnatural. The only way to reduce the misery of "poverty" is to provide ourselves with a more natural social environment.
	3)	The craving for retirement. Every culture refuses to believe that humans are animals that have been designed to live only long enough to reproduce, and this has resulted in modern cultures promoting the false concept that when we become old enough to retire, we will be in our golden years of life. In reality, if we live beyond age 50 or so, we are entering the dying phase of our lives. It would be more sensible to describe our golden years as being the first 45 years, and after that we slowly disintegrate. One reason people fantasize about retirement is because they do not enjoy their jobs, their city, or their social environment, and they are fantasizing that by retiring they will be able to avoid the unpleasant aspects of modern life and do whatever brings them pleasure. All of the social animals evolved to enjoy their group and the work they do. For example, prairie dogs do not fantasize about retiring from their "job" of digging tunnels and searching for food so that they can do what they want to do. They want to dig tunnels and search for food. They love working every day at that job, and they love living in their city, and they love living among other prairie dogs. However, if John Calhoun were to put some prairie dogs in a confined area, provide them with excessive amounts of food, and allow their population to become excessive, the prairie dogs would eventually dislike their city and the other prairie dogs. If we could go back in time to observe our prehistoric ancestors, we would find that they enjoyed looking for food, water, and shelter. We would not find any of them fantasizing about retiring or having vacations. We would not find any of them waking up in the morning and whining: "I have to spend another day looking for food. I'm so sick of this. Every day is the same. Look for food and water. Then look for a place to sleep. Then repeat that the next day, and the day after that, and so on, forever! I have a dead-end job. I'm stuck in a rut. I want to retire and be pampered by servants." However, when our ancestors settled into cities, they began doing jobs that were unnatural for humans. For example, farming is not a natural job for humans. Furthermore, the cities became increasingly miserable as a result of immigration and uncontrolled reproduction. The cities became increasingly overcrowded, ugly, and polluted, and the people began living among criminals, retards, beggars, and strangers. During the past few centuries, our jobs have become even more unnatural, and our cities have become extremely overcrowded, noisy, and polluted. Many cities are also a mixture of cultures and races, many of whom fear or hate one another. Most jobs today require us to go to school for years, but school is unnatural. To make schools even more annoying, many of the courses are worthless, which results in graduates having trouble finding a job. Our schools are also teaching a lot of false information about historical events, which can irritate the people who discover that they have been lied to. To make our jobs even worse, most people today are employees who, as mentioned in the previous section, spend their lives to make a few people absurdly wealthy.It is unnatural and unpleasant for us to be somebody's slave or servant. Many people assume that they dislike their job because "work" is bad, and that they will enjoy life when they retire, but the reason they dislike their job is because our jobs, economic system, and other culture is inappropriate for humans. If we could create better culture, we would love going to work, and we would consider retirement to be boring and miserable. We will not improve our lives by retiring. We need to alter our culture to eliminate the sources of misery that we are suffering from.

The people who design zoos try to make them as natural as possible for the animals, but no culture promotes the concept that there is such a thing as a natural environment for humans.

Most people believe that humans are either a creation of supreme being, or that our mind molds itself to our environment, and neither of those philosophies promote the concept that certain cities, jobs, or cultural activities are natural to us.

We cannot improve our lives simply by gathering more material items, becoming more famous, or by having more sex. We need to restrict leadership positions to people who understand that humans are a species of ape, and that we have genetic characteristics that cause us to prefer a certain type of environment, and suffer in other environments.

Our leaders also must understand that every species evolved to deal with certain types of irritations, and that they will suffer when their environment stimulates their unpleasant feelings beyond the extent that they were designed for, and that will cause their behavior to become abnormal.

All of the existing cities are putting us into an unnatural environment. In addition to being overcrowded, noisy, filthy, and ugly, they don't give us much access to nature. Humans evolved to be surrounded by birds, butterflies, trees, flowers, grass, and creeks, not asphalt parking lots, concrete sidewalks, or telephone poles.

We are also suffering because we were designed to live among people we enjoy and trust, but all of us are living among strangers, criminals, homeless people, lunatics, crime gangs, drug addicts, and different races and cultures that hate one another and speak different languages.

We must experiment with our culture to make it more appropriate for what humans truly are. For two examples of what this constitution will do to reduce the unpleasant stimulation:

	1)	Provide everybody with equal access to material wealth. That will prevent us from being stimulated into competing for material wealth, and prevent us from becoming angry, envious, or sad that some people have more wealth than we do. It also eliminates the problem of wealthy people who degrade our social environment with attitudes of superiority, and by flaunting their wealth.
	2)	Prohibit different classes of people. Everybody is of equal status, and nobody is in the role of a servant, and nobody is pampered or has any special privileges. This prevents employees from feeling as if they are slaves or servants who are pampering Kings and Queens. They will feel as if they are members of a team who are helping each other.

The population of our prehistoric, nomadic ancestors was kept under control by nature. However, when they settled into cities, they inadvertently put themselves into a variation of the mouse utopia experiment. The reason is because they began developing technology to provide themselves with large amounts of food. Instead of being provided with food by John Calhoun, they developed farms, ranches, irrigation systems, and other technology to provide themselves with lots of food.

By increasing their production of food, they allowed more of their children to survive, which caused their population to increase. As the population rose, the cities initially expanded onto more land, but since land is limited, the cities eventually had to increase the density of people in the city. This resulted in the people living with population densities that was beyond what humans had evolved for, which created the emotionally unpleasant environment that we refer to as "overcrowding".

To make their social environment even worse, some of the hungry people began to survive by begging for food, and others formed churches and charities that begged for donations. This allowed people to survive through handouts. Even worse, some people began to survive through crime.

The beggars and criminals were genetically inferior to the people that could take care of themselves in an honest manner. The result was that a lot of the inferior people were surviving and reproducing, thereby increasing the number of inferior people in every generation.

The past few thousand years of human history have been a variation of the mouse utopia experiment in which we have been using technology to prevent hunger, infant mortality, predators, and disease. However, instead of providing us with a heaven-like environment, it has resulted in cities that are overcrowded, filthy, ugly, and noisy. And it has allowed the human race to degrade genetically.

Schools should have a friendly environment, not the environment of a prison.

We have created cities that are emotionally unnatural for us, and this is resulting in unpleasant emotions being stimulated on a routine basis. That in turn results in us developing abnormal attitudes and behavior.

For example, children evolved for an environment in which they can trust the people they live with, so it is unnatural for us to teach children to be afraid of strangers, and to send them to school where armed policemen are watching over them.

We evolved to enjoy the people we live with, so it is unnatural for us to install security devices in our home, or put a fence around our home, in order to protect ourselves from our neighbors. We don't want to evict or euthanize the destructive people, but tolerating them is allowing them to torment the rest of us.

If the people had understood these concepts when they settled into cities, and if they had kept their population at an appropriate level by restricting reproduction to the higher-quality people, they would have created cities that were clean, spacious, orderly, quiet, and beautiful. They would have also continuously reduced the number of criminals, beggars, drug addicts, lunatics, and other misfits. They would have created cities in which the people were healthy, honest, and responsible.
More details about this concept are here.
