Look around you. What do you see?
Other people going about their business? Rooms with tables and chairs? Nature with its sky, grass and trees?
All that stuff, it’s really there, right? Even if you were to disappear right now — poof! — the rest of the world would still exist in all forms you’re seeing now, right? Or would it?
Cognitive scientist Donald Hoffman is trying to answer a big question: Do we experience the world as it really is … or as we need it to be? In this ever so slightly mind-blowing talk, he ponders how our minds construct reality for us. TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world’s leading thinkers and doers give the talk of their lives in 18 minutes (or less). Look for talks on Technology, Entertainment and Design — plus science, business, global issues, the arts and much more.
