Unfortunately, the category “pop psych” book has been misused and abused in the past, so that classification does not do the book justice.
Your Brain at Work is how a pop psych book should be: well-grounded in research, very well written and offering useful behavioral tips which follow directly from understanding how the brain works. As the cover of the book states: know your brain, transform your performance.
David Rock is really good at making neuroscience’s findings relevant to everyday’s life: each chapter opens with a snapshot of work life (e.g. a person having to make a decision, or dealing with pressure) and how it usually goes (wrong); then the author follows up by explaining why, according to current understanding of the brain, the person in the story behaves as he or she does; the chapter ends with a take 2, i.e. how the story could end differently if the person had understood how his or her brain worked (happy ending). Moreover, at the end of the chapter one can find two paragraphs: one with the title “Surprises about the brain” which summarizes the main points of the chapter and the other one, “things to try”, with some tips to make use of this understanding of how the brain works.
