What is Big Think's mission?

Our task is to move the discussion away from talking heads and talking points, and give it back to you. In practice, this means that our information is truly interactive. When you log on to our site, you can access hundreds of hours of direct, unfiltered interviews with today’s leading thinkers, movers and shakers. You can search them by question or by topic, and, best of all, respond in kind. Upload a video in which you take on Senator Ted Kennedy’s views on immigration; post a slideshow of your trip to China that supports David Dollar’s assertion that pollution in China is a major threat; or answer with plain old fashioned text. You can respond to the interviewee, respond to a responder or heck, throw your own question or idea into the ring.
