Contrary to the popular impression view that we are living in extraordinarily violent times, rates of violence at all scales have been in decline over the course of history. I explore how this decline could have happened despite the existence of a constant human nature.

About TEDx:
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
