Doesn't it bother you? To know that the person you are talking to, is mirroring your emotions, or offering sympathy, to manipulate you into liking them?
I very much prefer the Aspergers-like honesty. I would rather hear 9 harsh, blunt, honest criticisms a day and 1 genuine complement than to receive 10 fake, sugar-coated, vague, manipulative signals.
Don't think you'll be the only mastermind learning these and no one else will know about it. Keep in mind, if you do it, if you apply these techniques in your day to day interactions so will other people. And think about it for a second, from the perspective of a subject. Do you really want to be the subject to these social tricks and manipulations?
This thought truly bothers me. To hear a complement and not knowing if it was true and genuine or I was complemented simply because that person had read "How to influence people and win friends" last week and wanted to try his manipulation techniques on me.
Maybe instead of promoting these social skills we need to promote the appreciation of honesty and having some self control over our emotions.
