I am by no means as smart as these people but I did recently made this observation myself while visiting Google+. I try to avoid political discussions but someone always finds a way to insert them. This time, as I glanced over one such discussion it made me realize... People don't think, they just repeat things that have been told to them, fact or not, as long as it sounds like a good fit. No one involved in these discussions is going to convince the other to change their mind. AIs should be this easy!
