CORE DEFINITION
John Calhoun's rat experiments. In an environment with unlimited resources but limited space, rat populations eventually collapse due to overcrowding, leading to social behavioral breakdown (such as infanticide, violence, cannibalism, and social withdrawal), ultimately resulting in extinction, termed 'behavioral sink'.
SCAFFOLDING EFFECT
Reduce cognitive load
Reflect on high-density societies. It warns us that merely solving material scarcity (unlimited food) does not guarantee societal health; the pressure of social density and psychological space may lead to deeper civilizational crises.
Anchor fast decisions
Refers to John Calhoun's rat community experiments, where even with ample space and resources but extremely high density, the community still descends into behavioral breakdown, reproductive cessation, and social disintegration, suggesting that overcrowding itself can destroy social bonds.
