recurring) correspondences between the languages' phonology, grammar and core vocabulary, and through hypothesis testing; some persons with little or no specialization in the field sometimes attempt to establish historical associations between languages by noting similarities between them, in a way that is considered pseudoscientific by specialists (e.g. spurious comparisons between Ancient Egyptian and languages like Wolof, as proposed by Diop in the 1960s). The most common method applied in pseudoscientific language comparisons is to search two or more languages for words that seem similar in their sound and meaning. While similarities of this kind often seem convincing to laypersons, linguistic scientists consider this kind of comparison to be unreliable for two primary reasons. First, the method applied is not well-defined: the criterion of similarity is subjective and thus not subject to verification or falsification, which is contrary to the principles of the scientific method. Second, the large size of all languages' vocabulary and a relatively limited inventory of articulated sounds used by most languages makes it easy to find coincidentally similar words between languages. There are sometimes political or religious reasons for associating languages in ways that some linguists would dispute. For example, it has been suggested that the Turanian or Ural–Altaic language group, which relates Sami and other languages to the Mongolian language, was used to justify racism towards the Sami in particular. There are also strong, albeit areal not genetic, similarities between the Uralic and Altaic languages which provided an innocent basis for this theory. In 1930s Turkey, some promoted the Sun Language Theory, one that showed that Turkic languages were close to the original language. Some believers in Abrahamic religions try to derive their native languages from Classical Hebrew, as Herbert W. Armstrong, a proponent of British Israelism, who said that the word British comes from Hebrew meaning 'covenant' and meaning 'man', supposedly proving that the British people are the 'covenant people' of God. And Lithuanian-American archaeologist Marija Gimbutas argued during the mid-1900s that Basque is clearly related to the extinct Pictish and Etruscan languages, in attempt to show that Basque was a remnant of an "Old European culture". In the (1625), the Dutch lawyer Hugo Grotius "proves" that the American Indians (Mohawks) speak a language () derived from Scandinavian languages (Grotius was on Sweden's payroll), supporting Swedish colonial pretensions in America. The Dutch doctor Johannes Goropius Becanus, in his (1580) admits ("Who does not love his
