I'm going to assert that my definitions are correct by virtue of being the most logically consistent and everyone else should adjust their views accordingly.

But the theory is also easily testable. E.g. you can measure the humor response to unexpected events that violate the laws of physics verse unexpected events that don't violate the laws of physics. The Baillargeon toy car experiment I wrote about this is a good example of that, albeit that's not what it was designed to test.
