TED Radio Hour

Violence and brutality are grim realities of life. So why are some people violent, and others aren't? In this hour, TED speakers explore the sinister side of human nature, and whether we're all capable of violence.

Memory is malleable, dynamic and elusive. When we tap into our memories, where's the line between fact and fiction? Can our memory play tricks on us? Can we train it to be more accurate? TED speakers discuss how a nimble memory can improve your life, and how a frail one might ruin someone else's.

You can give away almost anything — your time, money, food, your ideas. Giving helps define who we are and helps us connect with others.

In this hour, stories from TED speakers who are "giving it away" in new and surprising ways, and the things that happen in return.

We try so hard to be perfect, to never make mistakes and to avoid failure at all costs. But mistakes happen — and when they do — how do we deal with being wrong?
