An AP Psychology teacher wrote a song enumerating several types of cognitive bias -- the blindspots in our thinking -- for his students. It's catchy, it's educational, and it might save you from getting conned, voting for a bastard, or having a stupid fight with your spouse!
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
