Abstract: In the seventies Bandler and Grinder (1975, 1979; Grinder & Bandler, 1976) developed their model of Neuro-Linguistic Programming (NLP). The aim of this model is to facilitate communication between persons (Particularly between counselors and clients). There is a growing body of literature on NLP; it is nowadays even used in a police context (Gray, 1991; Mayers, 1993; Rhoads & Solomon, 1987). What does NLP mean? To what extent does empirical research support the NLP-model? And, to what extent is NLP useful for the police? This article addresses these three questions.
