Sep 18, 2026 · 47m
Summary
Hosts Josh and Chuck explore the phenomenon of doppelgangers, discussing the term's origins, historical folklore, and the work of photographer François Brunel. They examine a study revealing that unrelated lookalikes share specific genetic markers while differing epigenetically, and analyze the neuroscience of facial recognition via the fusiform gyrus. The episode also covers real-world viral encounters, such as Neil Douglas meeting his double on a flight, and addresses the biases in AI facial recognition systems.
