It is quite common to be in discussions about worldviews and scientific evidence and the issue of falsifiability comes up. Usually, one side offers several pieces of evidence that they believe shows the other worldview to be false, but the other person has a logical answer to rebut their claims of incompatibility. The skeptic, in frustration, often claims that the opposing view is therefore "unfalsifiable" on the adherent's view. The skeptic believes that the other person is somehow cheating and denying the possibility that their worldview could be falsified. For if something is not falsifiable, then it cannot be considered scientific (and is often labeled as "pseudoscience"). The term "unfalsifiable" is tossed around a lot, but it is unclear whether those hurling it at their "opponents" actually know what it means or how to properly apply it to the opposing worldview (or their own). So today I want to take some time to examine falsifiability to clear up some misconceptions.
