Psychopathic manipulation techniques from "summary" of Defense Against the Psychopath: A Brief Introduction to Human Predators by MR Stefan H. Verstappen

Deception and lying are common manipulation tactics employed by psychopaths. They often use flowery language to make their stories believable. Alternatively, they may also attempt to control through waves of empty threats or promises.

Gaslighting, a further manipulation technique often seen within emotionally abusive relationships, is when one person psychological manipulates another into questioning their own sanity and memories. This tactic plays on victim's minds making them think they’re “crazy” and not capable of making rational decisions.

A common but effective manipulation method involves convincing their target that all choice options are bad for them. By offering limited viable solutions, pathologically controlling individuals are able to force the victim into submission.

Behavior that appears to be kind, helpful, generous, or sympathetic may actually be part of a manipulative scheme. These people typically give something conditional on the expectation of something in return.

Even small amounts of apparent kindness can be used to exert control over victims. This allows psychopaths to develop an uneven power dynamic with their targets.

Oftentimes, pathological manipulators will try to isolate someone from their support system. This further perpetuates feelings of helplessness and dependency by taking away the persons access to outside help or resources.

Threats or intimidation, while often exacerbated by alcohol or drug abuse, is still a form of manipulation. The goal is to scare the subject into submission and discourage any sort of resistance.

Fear mongering is utilized by malicious manipulators who take advantage of people's natural bouts of anxiety. Such individuals deploy exaggerated warnings about potential outcomes to push their targets towards a desired outcome.
