A major failing in the book is poor proofing and editing. There is no excuse for more than 30 typographical errors/misspellings in the first 200 pages. In addition, most of the references are dated, and a few are simply wrong in their exact citations. The authors presumably delegated too much to the publishing house and trusted their assistants to look at the proofs. What saves the book is lucid style, brevity, and pragmatism—all welcome in a field too much encumbered by ponderous writing and untested theories. For instance, how is this for succinctness in describing a sociopath? "A charming manner, lack of guilt or remorse, absence of anxiety, and a failure to learn by experience are said to be characteristics of sociopathy. The easy going, open, and winning style, when present, presumably accounts for the sociopath's success as a confidence man" (p. 262).
