Overpopulation in a mouse colony leads to violence, asexuality, and self-destruction, highlighting the negative effects of overcrowding and the need for social roles
In 1972, John B.Calhoun built an utopia for mice.
Every aspect of Universe 25, as this particular model was called, was designed to cater for the well-being of its rodent residents, increase their lifespan, and allow them to mate.
It was not the first time the ethologist had built a world for rodents. Colhoun had been creating utopian environments for rats and mice since the 1940s, with consistent results: overpopulation leads to explosive violence and hypersexual activity, followed by asexuality, self-destruction, and extinction.

Key Insights
- 🤔 The experiment challenges the notion that providing all basic needs and eliminating threats will result in a harmonious society, highlighting the complexities of social dynamics.
- 🌍 The Universe 25 experiment raises questions about the impact of overpopulation on social dynamics and individual well-being.
- 😱 The prevalence of cannibalism, asexuality, and violence in the mouse population demonstrates the extreme consequences of overcrowding and resource scarcity.
- 🐭 The mouse population in the experiment reached a peak of 2,200 before declining rapidly, indicating a collapse in mouse society and potential extinction.
- 🐭🔥 The experiment showed that overpopulation can result in explosive violence and hypersexual activity among mice, followed by asexuality, self-destruction, and extinction.
- 🐭 Calhoun's research suggests that when the number of individuals exceeds the available social roles, violence and disruption are inevitable.
- 🐭 The question arises whether overcrowding is a danger for mankind or if it only affects rodents, and what can save the human psyche from its ill effects.
