Scientific Research

The number of scientific studies about NLP is constantly increasing. Please help to keep this page up to date.

Neuro-Linguistic Programming is currently being studied in universities all around the world. Please send us links to new studies. This is an important measure to get NLP the recognition it deserves. The more as scientific community seems to be biased towards NLP.

Gatekeeping in Science: Lessons from the Case of Psychology and Neuro-Linguistic Programming

In their conclusion, the authors of this study (March 2024) Katherine Dormandy & Bruce Grimley write. 
"We have examined a complex case of gatekeeping in science and discovered faults on all sides. Psychology’s gatekeeping against NLP is understandable due to the public presentation of some NLP-ers, but it is bad gatekeeping. It rather reflects flat-out bias, straw-manning and highly problematic empirical analyses.- For this reason alone, psychology’s gatekeeping is bad – it violates the ideals it seeks to protect."

PTSD - Post Traumatic Stress Disorder

The Research and Recognition Project (R&RP)

conducts rigorous, controlled clinical studies to validate therapeutic techniques that support the widespread use of innovative and cost-effective clinical care for traumatic stress and a number of other psychiatric disorders. The Research and Recognition Project was founded in 2006, after a clinician and former lecturer at Cornell University, Dr. Frank Bourke, discovered the clinical efficacy of a protocol to treat post-traumatic stress.

This protocol is based on the principles of NLP (Neuro-Linguistic Programming). It is named Reconsolidation of Traumatic Memories (RTM).

In the last two years, sufficient research has been done to prove the initial clinical results.

King's College London

Another group of researchers at King's College in London UK, is doing clinical studies on the efficacy of the RTM protocol. A first feasibility study has been concluded (March 2024)

(-) Reconsolidation of traumatic memories protocol compared to trauma-focussed cognitive behaviour therapy for post-traumatic stress disorder in UK military veterans: a randomised controlled feasibility trial. ("Forty-eight percent of the RTM group no longer met diagnostic criteria for PTSD compared to 16% in the TFCBT group. All veterans reported largely positive experiences of the therapy and research procedures and ways to improve them.")

Based on this study a grant has been approved. The researchers write: "The new trial gives full credit to the NLP provenance, including RTM, VKD, Rewind and other variations, and is publicly out as a, revised over many years of work by many individuals, NLP intervention. We are also looking at mechanisms, so testing a series of hypotheses of how we think this might be working. NHS trial has already commenced and the full scale veterans trial will proceed after ethics approval next year." (April 2024)
