And now to a question that some of you are burning to know the answer of: “Is the falsification principle falsifyable?” I once read, I don’t know if it’s true, that Karl Popper used to kick his students out of the classroom for asking such a question. The falsification principle is that what its name says, it is a principle and not a scientific theory. No, the falsification principle itself is not falsifyable, it is not scientific. It belongs to metascience, or philosophy. Don’t forget: the scientific method – hypothesis, experimentation, observation, conclusion – is also not falsifyable, still it is used by scientists on a daily basis.
