The book claims to link behavior and the inner workings of the human brain. All chapters are built using the same method: a more or less anecdotal example written in a catchy and sensationalist style and a description of what is supposed to have happened in the brain of the protagonist (chemical-electrical functioning of the organ thought). Only "skill": the author does not explicitly say that it demonstrates the link between the two, he just let it think ... Typical example of the bad book of pseudoscience, written by an author who has no academic qualifications or research to address the topic. Typical of the genre: no page footnotes to refer to sources or studies in support of the "demonstration". The book is obviously intended readership IT / FHM but misses the mark by not even being thick enough to keep the towel on the sand.
