Abstract

This chapter focuses on one of the common fallacies in Western philosophy called 'unfalsifiability'. The unfalsifiability fallacy occurs when someone makes a claim that is impossible to prove false. Falsifiability – the ability to be falsified or proven wrong – is considered a key criterion for deeming a hypothesis scientific. Conspiracy theories often rely on unfalsifiable claims in which the theorist ardently defends a theory despite any facts that disprove it, suggesting only, “Well, it's a conspiracy. It's impossible to disprove”. Once the criterion of falsifiability has been established, it is important to examine a statement or theory more critically. The defense of horoscopes not only involves an unfalsifiable claim but can also involve anecdotes. As it turns out, when tested objectively, claims made by horoscopes tend to be false considerably more often than many people recognize.
