What's Your Favorite Pet Theory?

There is this Michael Gazaniga who does, who is working with split brain patients. And so if you show something to the right hemisphere and that results in a behavior, like for example, the patient then draws what it was that you said or showed to them. The left hemisphere, when you ask it, why did you do that? Doesn't just say, I don't know. It essentially will say, because I felt like it. We make up stories to sort of make sense of the world.
