I have absolutely no idea how well-versed in NLP the authors of this book may be, but whatever the level of their knowledge, what comes across in this book is so confused, and in many places so downright inaccurate, anyone genuinely knowledgable on the subject could be forgiving for thinking it was written by a couple of complete novices.
(Please note - this is a comment on the contents of the book, not about the authors.)Apart from anything else, as a reviewer in another place quite rightly noted, much of what is in the book isn't actually about NLP at all. On top of which the description of things neurological - such as the quite baffling description of the hippocampus - is largely pure gobbledegook:
'the hippocampus is made up of banks and banks of pyramid-like structures that get filled up during the day and emptied out at night? This means that you are able to make connections more quickly when you first wake up, so do your hardest thinking before the pyramids fill up.'
Before the "pyramids fill up"? You cannot be serious!
Apparently the authors have no idea whatsoever that what they are talking about are "pyramidal neurons" - the real "pyramids" in the brain are something else entirely. Moreover pyramidal cells aren't only found in the hippocampus, about 70 (seventy) per cent of the neurons in the neo-cortex are pyramidal.
On the same topic, what passes through neurons are minute electrical pulses which are transmitted to other neurons many times per second. So what the authors think the "pyramids" are "filling up" with, and why they are allegedly only "emptied out at night", is anyone's guess.
There are many other mistakes in the book, of varying substance, and I won't waste your time by trying to list them all here. The point is already made, I think, that whatever research went into preparing the text was totally inadequate. And contrary to the claims made in previous reviews this is probably one of the worst introductions to NLP on the market today.
For a introduction to NLP that really does cover all the important information, accurately, O'Connor and Seymour's 'Introducing NLP' is still the one to watch.
