A bunch of ideas are running around in Don Everts's head. Some are permanent residents. Others are visitors, just passing through. When they all get together, some odd things start happening. It's one thing when the idea Girls Are Kind Of Icky gets challenged by Girls Can Be Pretty Darned Interesting. But it gets more complicated when The Old Man Clutching The Big Black Bible meets Higher Criticism. Or when You Are Not Loveable tries to drown out the voice of God Loves You. In this tour of Don's head, you get a glimpse of how we make sense of ideas and how we decide which ones should live with us. We're introduced to back-door ideas like Pain Is Bad, secret ideas like Lighter Skin Implies Higher Intelligence, and sexy ideas like Shiny Happy Globalization. How do we determine what ideas win out? Which ideas should get to stay, and who should get kicked out of the house?
