Zététique (from Ancient Greek: ζητητικός zētētikós, "inquisitive", "keen") is a French term (both a noun and an adjective) for the application of the scientific method when investigating allegedly "paranormal" phenomena.[1] It is often seen as equivalent to, or somewhat different from, the term (scientific) skepticism (French: scepticisme (scientifique)), and is widely used in the modern skeptical movement in France for self-identification.


The word seems to have entered the French language around the 17th century. The oldest known reference is found in the Dictionnaire des Arts et des sciences (1694), II, p. 615, wherein the Methode zetetique is the method to resolve a mathematical problem.[2]

In the Littré dictionary of 1872, zététique is referred to as an educational term about research, especially as a method to resolve a mathematical problem, and in general a method to "penetrate the reason of things". Philosophes zététiques are described as "ancient philosophers who doubted everything."[2]

The 1876 Larousse dictionary, p. 1479, wrote thus:

The name of zététiques, which means seekers, indicates a rather original nuance of skepticism: it is provisional skepticism, it is close to Descartes' idea about doubt as a means, not as an end, as a preliminary procedure, not as a definitive result. If all skeptics really were zététiques and only zététiques, they would have said with Pyrrho: "We do not arrive at doubt, but at the suspension of judgement" (...) skeptics literally mean examiners, people who think, reflect, study attentively; but in the long run they take a more negative than doutbful stance, and has meant that those who are under the pretext of always examining never decide. (...) the word zététiques is not made to resolve the debate between the two meanings of all these terms (...) Moreover, the name zététiques has remained on the ground of the school that created it; and, despite its wide expansion, which would have helped make the term general for all seekers of truth in all fields, it is exclusively applied to skeptics, and we could even say to Greek skeptics or Pyrrhonists.[2]

Zététique is sometimes rendered as zetetic and zeteticism in English by Marcello Truzzi and others, who are critical of the modern skeptical movement and wish to use a different word to distinguish themselves.[3] The first few issues of the Skeptical Inquirer, of which Truzzi was the first editor, it was titled The Zetetic.[2]

Physics professor Henri Broch, who ran the International Zetetic Challenge (1987–2002) with Gérard Majax and Jacques Theodor, and in 1998 founded the Laboratoire de Zététique at the University of Nice Sophia Antipolis, defines zététique simply as "the art of doubt".[4]
