TED Radio Hour is a themed interview anthology, not a single-guest conversation show: each roughly 50-minute episode is organized around one idea (e.g., 'hidden forces,' 'coexistence,' 'perceiving the world') and stitches together two to five segments built from TED Talks. Host Manoush Zomorodi introduces the theme, narrates transitions between segments, and interviews the featured speakers directly. Guests vary episode to episode and are typically subject-matter experts -- biologists, psychologists, negotiation professors, neuroscientists, technologists, and activists -- rather than celebrities or fellow broadcasters. Recurring subject areas in the sample include cognitive science and memory reliability, artificial intelligence and its role relative to human judgment, negotiation and communication skills, emotional regulation, animal behavior, the cultural history of food, and conflict resolution or peacebuilding work. Some episodes stay in an explanatory, educational register (e.g., how otters coordinate hunts, how food norms formed after WWII), while others carry a narrative, personal-story structure (e.g., a peace activist's account of brokering a gang truce after losing family members to violence). The show is produced by NPR and includes sponsor reads and cross-promotion for other NPR programs at the open. Listeners who enjoy long-form, research-grounded explanations of psychology, science, and social issues -- delivered through a curated, multi-guest format rather than a single deep-dive conversation -- are the core audience. The format suits people who want breadth across a theme in one sitting rather than a single extended interview.
