Manipulation
Manipulation measures a character's ability for self-expression in the interests of getting others to share her outlook or follow her whims. In short, it's getting others to do what she wants. Manipulation comes into play when a character tries to influence or subtly guide another's behavior. Manipulation is used to trick, bluff, fast-talk and railroad other characters. Whether or not the characters in question actually like the manipulator is irrelevant (this is why Manipulation differs from Charisma); a skilled motivator can even employ the talents of people who hate her.
