“”To kill an error is as good a service as, and sometimes even better than, the establishing of a new truth or fact.
Charles Darwin[1]

Skepticism (or scepticism) is the art of constantly questioning and doubting claims and assertions, and holding that the accumulation of evidence is of fundamental importance. It forms part of the scientific method, which requires relentless testing and reviewing of claimed facts and theories. The “Skeptic” spelling is generally preferred on this website (but not in the liberal UK), in case people might infer that the “c” is silent, as in “science”.

Skepticism should not be confused with pseudoskepticism which is really a form of denialism.
