Hmm,

2 things, in the book Paul claims that the 'thinking cap' relates to the Tangerine effect.

No where in google can I find a reference to this, IE it's made up, there is no such thing as a tangerine effect.

Please can someone point out anywhere where it's mentioned that the term is related to anything about focusing on the back/top of your head.

Also I found this very interesting post by John Grinder, the 'father' of NLP, the same person that Paul mentions in the book. And has a signature from in the foreword.

Unfortunately John Grinder denies that he was asked to do this, and seems very surprised as he's had nothing to do with Photreading, please make up your own mind

Any studies NOT written by Paul about how photoreading works?

Any reason why the book has not been updated substantially since it was published, or why Paul doesn't post in this forum, or indeed why we only appear to have a single moderator?
