Robert Noggle:

Calling someone manipulative is a criticism of that person’s character. Saying that you have been manipulated is a complaint about having been treated badly. Manipulation is dodgy at best, and downright immoral at worst. But why is this? What’s wrong with manipulation? Human beings influence each other all the time, and in all sorts of ways. But what sets manipulation apart from other influences, and what makes it immoral?

We are constantly subject to attempts at manipulation. Here are just a few examples. There is ‘gaslighting’, which involves encouraging someone to doubt her own judgment and to rely on the manipulator’s advice instead. Guilt trips make someone feel excessively guilty about failing to do what the manipulator wants her to do. Charm offensives and peer pressure induce someone to care so much about the manipulator’s approval that she will do as the manipulator wishes.
