Neuro-linguistic programming (NLP) is a pseudoscientific approach to communication, personal development, and psychotherapy that aims to alter thoughts and behaviors to help achieve desired outcomes for individuals. It was developed in the 1970s by Richard Bandler and John Grinder, who believed it was possible to identify the patterns of thoughts and behaviors of successful individuals and to teach them to others. NLP uses perceptual, behavioral, and communication techniques to make it easier for people to change their thoughts and actions. It relies on language processing but should not be confused with natural language processing, which shares the same abbreviation. NLP tries to detect and modify unconscious biases or limitations of an individual’s map of the world. It is not hypnotherapy but operates through the conscious use of language to bring about changes in someone’s thoughts and behavior. Some key elements of NLP include modeling, action, and effective communication. NLP is used as a method of personal development through promoting skills, such as self-reflection, confidence, and growth mindset. It has been used to treat a wide range of issues, including anxiety, phobias, and depression. However, the scientific evidence supporting NLP is limited, and it is considered a pseudoscientific approach by many experts.
