The topic of this discussion was the book, not psychology, so I refrained from engaging and derailing the subject. But for context and clarification: The DSM is a reference manual on mental health and brain-related conditions, as well as personality disorders. It's used as a diagnostic tool by psychologists and psychiatrists worldwide. It's not perfect, nor complete. It keeps growing and evolving. For example, the DSM-II was around 134 pages. The DSM-5 is over 1000. Also, it's worth noting that the DSM-II was published in 1968, so it's unlikely to have been used as reference material for this book.
