Gaslighting means to drive someone crazy. It comes from the 1944 film Gaslight, in which a husband convinces his wife she's losing her mind. Gaslighting is the most potent form of psychological warfare you can use without a license. In this book, Santoro shows you how to destroy your target's confidence, self-esteem and reputation. Through a series of small incidents, your target gets progressively more confused, until he's reduced to a shapeless mass of shivering, quivering jelly. It will show you how to cause disorientation, get your target off balance and build up his paranoia.
