Great Lectures: Randomness, Skepticism and the Science of the Good Society

I recently listened to some great lectures so I thought I'd pass them on:
Randomness (listen to the first 25 min at least)
Why People Believe Weird Things (great, light, talk about how we perceive patterns in the world)
Then a two part talk with J.D Trout: First, on our Empathy Gap and then how to use Science to achieve a better Society.
