This comes from a book I've read and really liked. It's called "Get Anyone to do Anything" by David Leiberman, Ph.D.
I've used several of his ideas in real life and every one of them has worked believe it or not. Here's one:
How to tell if someone is trying to manipulate you.
From the bedroom to the boardroom learn how to see clearly and easily evaluate information without being swayed by those with selfish interests and unkind intentions. The manipulator's bag of tricks is stocked with seven deadly tactics that can have you jumping through hoops. The good news is that by knowing what they are, you can watch out for them, and...never be manipulated again?
These powerful manipulators are: guilt, intimidation, appeal to ego, fear, curiousity, our desire to be liked, and love. (Charlie here - sound familiar everyone?) Anyone who uses any of these is attempting to move you from logic to emotion--to a playing field that's not so level. He knows that he can't win on the facts so he will try to manipulate your emotions with any one or a combination of the tactics below.
Guilt: "How can you even say that? I'm hurt that you wouldn't trust me. I just don't know who you are anymore."
Intimidation: "What's the matter, can't you make a decision? Don't you have enough confidence in yourself to do this?
Appeal to Ego: "I can see that you're a smart person. I wouldn't try to put anything past you. How could I? You'd be on to me in a second."
Fear: "You know, you might just lose this whole thing. I sure hope you know what you're doing. I'm telling you that you won't get a better deal anywhere else. This is your last shot at making things work out; why do you want to risk losign out on being happy?"
(Charlie here, another very familiar one in A recovery, eh? i.e. "You can't ever forgive me so maybe we should just divorce.")
Curiosity: "Look, you only live once. Try it. You can always go back to how things were before. It might be fun, exciting--a real adventure. You'll never know unless you try and you may regret never even seeing what happens."
Our Desire to be liked: "I thought you were a real player. So did everybody else. This is going to be a real disappointment if you don't come through for us. Come on, nobody likes it when a person backs out...this can be your chance to prove what you're made of."
Love: "If you loved me you wouldn't question me. Of course I have only your best interests at heart. I wouldn't lie to you. You know that deep down inside, don't you? We can have a wonderful relationship if only you'd let yourself go and experience the wonders that the future will deliver to us."
This book also has chapters on:
Does his story check out?
(That one is a way to tell if someone is lying every time and it works b/c I tried it with ex.)
Get anyone to say what he's really thinking.
Get anyone to follow through on a commitment to you.
Stop Verbal Abuse Instantly.
Get anyone to open up to you.
Get anyone to confide in you and confess anything.
and more but I'm tired of typing and some are not as important.
