Episode Details

That eerie sensation of having lived through a moment before—déjà vu—is one of the most common cognitive quirks, yet its mechanics reveal something profound about how memory actually works. In this episode, we explore the dual-processing theory that explains why your brain sometimes signals "this is familiar" when it shouldn't. From virtual reality experiments that can trigger the sensation on demand to the epilepsy patients who experience it as a seizure aura, we unpack what the phenomenon reveals about the reconstructive nature of memory. Along the way, we debunk the myth that déjà vu predicts the future and show how it's actually a false positive in your brain's lightning-fast familiarity detection system.
