Valuable skills for many walks of life
Dark psychology sounds like sometjing ominous, but it can in fact impart skills that can be valuable in life. Many people don't realize it but persuasion can be a useful skill to have. For example, salesmen of all kinds rely heavily on persuasion to close dealsm. So, as the author notes these are things that are not nefarious but can be necessary. Of course the author notes there can be people who manipulate and do bad things, but that is not the focus here. I enjoyed reading this book.
