It seems our brains are constantly making predictions about our environment. To illustrate, Jeff Hawkin's often uses a coffee cup and the expected sensations when going to grab it.
What seems fun about this idea is how it relates to the abstract. What if there were an object that defied classification, never satisfying the predictions that the brain has made? It wouldn't have to be a physical object either. Let's try it with language.
Right now, as you're reading you're trying to follow along and predict what I will write next. Paper straw. Doubt you were expecting that. I suspect your brain is now kind of backing away slowly because man I could write anything. A literal madman wiith a keyboard. I like plastic.
Instead of surprise, how about ambiguity? It is on the surface. What is it? What surface? Is it moving or what? What kind of thing even is it? Might be fun to write something longer that plays more with ambiguity and surprise. For now I'll just say it's a paper straw on the table. GM
