Abstract: The paper presents general characteristics for pseudo-scientific theories and concepts. Quotes from the literature prove that Neuro-linguistic Programming (NLP) is a pseudo-scientific approach: (1) A scientific evaluation of the claimed exceptional effects is generally rejected by the NLP developers. (2) Technical quotations and terminology are associative, inaccurate and distort theories and methods of well-known scientists and can to a certain extent be regarded as constructed fakeknowledge. (3) Basic models such as the representation systems and especially the effectiveness of the methods cannot be confirmed by scientific studies and negative research results are concealed. Overall NLP can be regarded as a degenerative pseudo-scientific program. Doubts are appropriate whether it is possible to improve NLP in the future by methodically careful scientific research.
