Beware the Power of Prediction | Carissa Véliz | TED

What do the story of Oedipus and your insurance premiums have in common? They are both driven by self-fulfilling prophecies. Philosopher and TED Fellow Carissa Véliz traces the hidden power of prediction, from Roman emperors who banned prophets to the AI algorithms quietly making decisions about your life right now. We tend to associate predictions with knowledge, she says, but they're actually attempts to grab power. So the next time someone tells you a specific outcome is inevitable, remember: they aren't describing the future — they're selling it.
