Scientific skepticism (also spelled scepticism) is the practice of questioning whether claims are supported by empirical research and have reproducibility, as part of a methodological norm pursuing "the extension of certified knowledge".[1] Scientific skepticism, or skepticism for short, manifests itself since the 20th century as a societal phenomenon involving several individuals and more or less organised groups through several different media, commonly referred to as "the skeptical movement".[2] This is a compilation of the various lists about skepticism with articles in Wikipedia.
