They may not be related, but having a good understanding of the psychological NLP actually lends it self really well to NLP and prompt engineering. As much as a lot of people 'claim' it to be parapsychology (even within this thread), check out books like Strategies of Genius and how it breaks down a lot of the main concepts. It's very 'meta-cognition' if you will, but, the parallels are eye opening given how long the concepts have been around. If someone has never done serious mind mapping or brain storming and entity-node relationship type work with databases, it would be quite a leg up helping them understand and mentally map out concepts like that.
