want government to implement policies that are informed by scientific knowledge, but i feel like part of the problem that when science becomes politicized, then both sides use it and manipulate it at times to promote an agenda that can completely subvert science. >> well, guys, coming back to the debate tonight, i put the question out to twitter, what would you -- what would you change about debates? what would you add to them? how would you modify them? overwhelmingly the response that i got was realtime fact checking. i sta rted to think about how could that actually work? the problem is as you were saying, steve, even if you had a fact checker there from politifact or fact check.org or "the washington post" or whoever it was, that would be up for debate, too. there is no person -- trust in our large institutions is at such low levels, there is no person or no thing that everyone would trust. i was actually trying to come up with if there was a crowd source way, sort of like a rotten tomatoes site for fact checking
