Excellent, that’s exactly what I was looking for, thank you.There's a book on dark psychology in the WF Library but it's an old post with a dead link. Welib.org has many different books with "Dark Psychology Secrets" on, you could download them one by one and check what's suitable for you. My (prejudiced) hunch, however, is that they're mundane self-help books for poor shmucks with low self-esteem who'll invariably lack the required self-confidence to ever pull off the tricks described in those books on a one-to-one basis.
In his "Liber Kaos", Peter J. Carroll takes a different approach: his Yellow Magic (solar) involves work on oneself to build charisma and then using it to influence people. Green Magic (Venusian) would also be an option, becoming popular probably is more efficient than the most sophisticated NLP tricks.
Therefore, I'd rather look for books on general magic than those narrowly focusing on psychological stunts. After all, affecting one's fellow persons is a big part of magic, I wouldn't put very much trust in cheesy self-help tomes.
