The Mouse Utopia That Fell Apart: A SPECIAL One Part Podcast Episode for Kids

Daniel Mault Season 4 Episode 106

What happens when a society has everything it needs: food, safety, comfort, but still collapses?

In this episode, we tell the true story of Universe 25, a famous mouse experiment by researcher John B. Calhoun that explored population growth, social behavior, and the breakdown of community in a resource-rich environment. Often misunderstood and dramatized online, this episode separates myth from science and explains what Calhoun actually observed and what he warned us not to conclude.

A story about behavioral sink, social roles, belonging, and meaning, this episode invites listeners to rethink what “utopia” really means and why survival alone isn’t the same as living.
