Neuro-linguistic programming (NLP) is an approach to communication, personal development, and psychotherapy created by Richard Bandler and John Grinder in California, the United States in the 1970s. NLP's creators claim there is a connection between neurological processes (neuro-), language (linguistic) and behavioral patterns learned through experience (programming), and that these can be changed to achieve specific goals in life. Bandler and Grinder also claim that NLP methodology can "model" the skills of exceptional people, allowing anyone to acquire those skills. They claim as well that, often in a single session, NLP can treat problems such as phobias, depression, tic disorders, psychosomatic illnesses, near-sightedness, allergy, common cold, and learning disorders.
NLP is marketed by some hypnotherapists and by some companies that organize seminars and workshops on management training for businesses. There is no scientific evidence supporting the claims made by NLP advocates and it has been discredited as a pseudoscience. Scientific reviews state that NLP is based on outdated metaphors of how the brain works that are inconsistent with current neurological theory and contain numerous factual errors.
