Are there undiscovered people?

This Stuff You Should Know episode dives into the fascinating world of so-called "undiscovered" tribes after examining the media frenzy surrounding 2008 photos of indigenous people in Brazil aiming arrows at helicopters. Josh and Chuck explore the important distinction between truly undiscovered peoples versus uncontacted or isolated tribes who have deliberately chosen to avoid modern civilization. The hosts discuss the ongoing threats these communities face from disease, violence, and encroachment by logging, oil, and agricultural interests, while also examining our complex history of contact with indigenous peoples and the ethical questions surrounding whether we should leave these groups alone.
