Over the years I have seen a lot of discussion on the topic on ENFPs being manipulative, especially between ENTPs and ENFPs.
It seems that when we are young, we can be very manipulative, but it isnt really conscious or planned very well, as a Ti user would plan-we simply mold to the other person, then adapt to fit thier needs and then we sort of shift into thier emotional space-a bit of a probe to develop a feel for what they need? We will actually reach out with Ne and actualy explore ideas, influence others, never really becing conscious of our own motives or needs-it just feels like a scratch to be itched, so to speak, which as we scratch, we influence. There is an interesting innocence to this activity as it isnt pre-mediated, more reflexive in nature...it feels very fluid. We are simply being sweet? It doesnt feel like you are causing hurt or actively trying to make the other person do something-you simply are and they respond to that.
As we get older, we become more aware of the ability to influence and manipulate and different enfps will use this ability in different ways based upon thier values.
I actively influence my customers for instance-I want them to feel secure that I have thier best interest at heart. However it is a sincere, authentic value I hold, thus it is very easy to come across as honest and this works to shift customer perspective. Since I am sincere in my values towards them, and I take action on thier behalf, I am okay influencing them. But I could not consciously manipulate another person in a way that would hurt them or not be in thier best interest-it feels horribly disgusting. Lol, I wouldnt even be any good at it, since it would make me feel bad and I would then come across as hollow or fake.
