Unpredictability and Uncertainty (Intermittent Reinforcement)
The abuser acts unpredictably, capriciously, inconsistently and irrationally. This serves to render others dependent upon the next twist and turn of the abuser, his next inexplicable whim, upon his next outburst, denial, or smile.
The abuser makes sure that HE is the only reliable element in the lives of his nearest and dearest - by shattering the rest of their world through his seemingly insane behaviour. He perpetuates his stable presence in their lives - by destabilizing their own.
Refuse to accept such behavior. Demand reasonably predictable and rational actions and reactions. Insist on respect for your boundaries, predilections, preferences, and priorities.
One of the favorite tools of manipulation in the abuser's arsenal is the disproportionality of his reactions. He reacts with supreme rage to the slightest slight. Or, he would punish severely for what he perceives to be an offence against him, no matter how minor. Or, he would throw a temper tantrum over any discord or disagreement, however gently and considerately expressed. Or, he would act inordinately attentive, charming and tempting (even over-sexed, if need be).
This ever-shifting code of conduct and the unusually harsh and arbitrarily applied penalties are premeditated. The victims are kept in the dark. Neediness and dependence on the source of "justice" meted and judgment passed - on the abuser - are thus guaranteed.
Demand a just and proportional treatment. Reject or ignore unjust and capricious behavior.
If you are up to the inevitable confrontation, react in kind. Let him taste some of his own medicine.
Dehumanization and Objectification (Abuse)
People have a need to believe in the empathic skills and basic good-heartedness of others. By dehumanizing and objectifying people - the abuser attacks the very foundations of human interaction. This is the "alien" aspect of abusers - they may be excellent imitations of fully formed adults but they are emotionally absent and immature.
Abuse is so horrid, so repulsive, so phantasmagoric - that people recoil in terror. It is then, with their defences absolutely down, that they are the most susceptible and vulnerable to the abuser's control. Physical, psychological, verbal and sexual abuse are all forms of dehumanization and objectification.
Never show your abuser that you are afraid of him. Do not negotiate with bullies. They are insatiable. Do not succumb to blackmail.
If things get rough - disengage, involve law enforcement officers, friends and colleagues, or threaten him (legally).
Do not keep your abuse a secret. Secrecy is the abuser's weapon.
Never give him a second chance. React with your full arsenal to the first transgression.
Abuse of Information
From the first moments of an encounter with another person, the abuser is on the prowl. He collects information. The more he knows about his potential victim - the better able he is to coerce, manipulate, charm, extort or convert it "to the cause". The abuser does not hesitate to misuse the information he gleaned, regardless of its intimate nature or the circumstances in which he obtained it. This is a powerful tool in his armory.
Be guarded. Don't be too forthcoming in a first or casual meeting. Gather intelligence.
Be yourself. Don't misrepresent your wishes, boundaries, preferences, priorities, and red lines.
Do not behave inconsistently. Do not go back on your word. Be firm and resolute.
The abuser engineers impossible, dangerous, unpredictable, unprecedented, or highly specific situations in which he is sorely needed. The abuser makes sure that his knowledge, his skills, his connections, or his traits are the only ones applicable and the most useful in the situations that he, himself, wrought. The abuser generates his own indispensability.
Stay away from such quagmires. Scrutinize every offer and suggestion, no matter how innocuous.
Prepare backup plans. Keep others informed of your whereabouts and appraised of your situation.
Be vigilant and doubting. Do not be gullible and suggestible. Better safe than sorry.
