Neuro-linguistic programming has been repeatedly criticized. It is often called manipulative, not least because cults like the Church of Scientology use these practices.
The central problem, however, is the overestimation of its effectiveness by users who sometimes make NLP look dubious. NLP has become virtually independent in its further development over the decades. There are now countless publications in which practically every author has contributed their own ideas and views. The use of tools and representation of models is often done entirely at your own discretion.
Laypeople who have learned certain methods may be tempted to use these methods in healing therapies. However, this can have dangerous consequences, especially in combination with trance induction, trauma treatments, or confrontation therapy – particularly if the methods are used incorrectly. That’s why professional training that creates risk awareness and teaches the correct application of the methods should have top priority.
