To manipulate people.
A feeler does not see it this way. They do not see themselves as manipulating. What are the real reasons for being nice?
I think you're being way too broad with that statement too, I'm sure lots of feelers are aware they're being manipulative.
Your original post was in the form of an absolute. "To manipulate people." I adopted the assumption that we were speaking of generalizations.
Regardless, you cannot even prove that most are manipulating on purpose unless you can get inside their heads and retrieve the truth and do it on a large scale.
