Which NPR podcast has a Latin title meaning “invisible things”? The answer is Invisibilia.

NPR’s Invisibilia explored the unseen forces shaping human behavior, including beliefs, emotions, assumptions, and ideas. Its title comes from the Latin phrase meaning “the invisible things,” making the clue a direct translation rather than a reference to the show’s format.

The podcast debuted in 2015, created by NPR journalists Alix Spiegel and Lulu Miller. Its first season contained six episodes and quickly became a major podcast success, reaching the top of Apple’s podcast chart after launch. Former hosts also included Hanna Rosin, while later seasons were hosted by Kia Miakka Natisse and Yowei Shaw.

A common mix-up is Radiolab, another NPR-associated audio program whose former producer Lulu Miller helped create Invisibilia. Invisibilia ended in 2023 after nine seasons and 62 episodes.
