A book which cover very many different subjects, probably too many. A lot of space is given for different memory techniques. Other main subjects are hypnosis, unconscious communication and pseudo-science. Some of the subjects are pretty interesting, especially those involving cold-reading and pseudo-science, nothing really new, though. (Bad Science by Ben Goldcare handled those things much better and with more detail) The parts about memory (and partly that involving hypnosis) seem to be partly padded, and several pages are used extremely detailed memory techniques or hypnosis directions, which were “a bit“ boring. A fair amount of condensing might have made these book more interesting.
