TED Talk: Steven Pinker: The surprising decline in violence

Wow, not sure why I have not posted this one yet. In college, I was one of four students who showed up to the showing of a video of Pinker talking about his book How the Mind Works. It reinforced for me Psychology was a good choice for me.

So this talk on decline in violence seems appropriate for September 11th.

If the below video does not work, then try Steven Pinker: The surprising decline in violence.
