What happens when a society has food, water, shelter, and safety—yet still begins to fall apart?
In Episode 7, we explore John B. Calhoun’s famous Universe 25 mouse experiment—who Calhoun was, why the experiment began in 1968, what happened to the mice, the “Beautiful Ones,” why scientists use mice instead of humans, and why this experiment became so widely discussed.
We also look at the similarities people see between Universe 25 and modern human society—social roles, withdrawal, reproduction, aggression, community, and connection—while separating scientific evidence from internet exaggeration.
And nearly 60 years later, researchers are still revisiting Calhoun’s work, including a 2026 computer-modeling study examining the experiment again.

Do you think Universe 25 shows real similarities to society today, or have we taken the comparison between mice and humans too far?
