Abstract: The huge popularity of neuro-linguistic programming (NLP) over the past three decades has in some ways mirrored the growth in coaching psychology. This paper is part of a series of four papers in a special issue within ICPR that aims to explore NLP coaching from diverse perspectives, offering personal insights or reviews of evidence. As part of this process a pair of authors were invited to advance the case for and the case against NLP. This paper aims to adopt a critical stance; reviewing the concept of NLP, exploring the claims made by advocates and critically reviewing the evidence from a psychological perspective. In undertaking this review we completed a series of literature searches using a range of discovery tools to identify research papers, based on pre-determined search criteria. This review led us to the conclusion that unique NLP practices are poorly supported by research evidence.
