McGurk Effect 1, Naive Realism 0

I tweaked someone else's image using GIMP. You can find the original at
Naive realism means different things to different people. I give a rough definition of how I think about it, write about what I like about it, but also why I inevitably think it in unsupportable. My main example for this is the McGurk Effect, a perceptual illusion that occurs when what you see changes what you hear. I also take the opportunity to drop in some references to David Chalmers and Alfred North White Head.
