Perhaps manipulation is wrong because it involves techniques that are inherently immoral ways to treat other human beings. This thought might be especially appealing to those inspired by the idea that morality requires us to treat each other as rational beings rather than mere objects. Perhaps the only proper way to influence the behaviour of other rational beings is by rational persuasion, and thus any form of influence other than rational persuasion is morally improper. But for all its appeal, this answer also falls short, for it would condemn many forms of influence that are morally benign.

Is Manipulation Wrong Because It Is Morally Dubious?

What makes an influence manipulative and what makes it wrong are the same thing: the manipulator attempts to get someone to adopt what the manipulator herself regards as an inappropriate belief, emotion or other mental state. In this way, manipulation resembles lying. What makes a statement a lie and what makes it morally wrong are the same thing – that the speaker tries to get someone to adopt what the speaker herself regards as a false belief.In both cases, the intent is to get another person to make some sort of mistake.

The Resemblance Between Manipulation And Lying 

The liar tries to get you to adopt a false belief. The manipulator might do that, but she might also try to get you to feel an inappropriate (or inappropriately strong or weak) emotion, attribute too much importance to the wrong things (eg, someone else’s approval), or to doubt something (eg, your own judgment or your beloved’s fidelity) that there is no good reason to doubt. The distinction between manipulation and non-manipulative influence depends on whether the influencer is trying to get someone to make some sort of mistake in what he thinks, feels, doubts or pays attention to.

Who’s Worse? The Liar Or The Manipulator?

For example, much of Iago’s manipulation involves appealing to Othello’s emotions. But emotional appeals are not always manipulative. Moral persuasion often appeals to empathy, or attempts to convey how it would feel to have others doing to you what you are doing to them.

Morally Benign Influence 

It is endemic to the human condition that we influence each other in all sorts of ways besides pure rational persuasion. Sometimes, these influences improve the other person’s decision-making situation by leading her to believe, doubt, feel or pay attention to the right things; sometimes, they degrade decision-making by leading her to believe, doubt, feel or pay attention to the wrong things.But manipulation involves deliberately using such influences to hamper a person’s ability to make the right decision – that is the essential immorality of manipulation.

How To Recognize Manipulation

So, if we are to recognise manipulation, we must look not at the form of influence, but at the intention of the person using it. For it is the intention to degrade another person’s decision-making situation that is both the essence and the essential immorality of manipulation.

Was There Intent?

It is tempting to think that manipulation is a kind of influence. But as we have seen, kinds of influences that can be used to manipulate can also be used non-manipulatively. What matters in identifying manipulation is not what kind of influence is being used, but whether the influence is being used to put the other person into a better or a worse position to make a decision.

Were There Damages?

Similarly, getting someone to fear something that really is dangerous, to feel guilty about something that really is immoral, or to feel a reasonable level of confidence in one’s actual abilities, do not seem like manipulation. Even invitations to doubt one’s own judgment might not be manipulative in situations where – perhaps due to intoxication or strong emotions – there really is good reason to do so. Not every form of non-rational influence seems to be manipulative.

Not Every Form Of Non-rational Influence Is Manipulative

Manipulative gaslighting occurs when the manipulator tricks another into distrusting what the manipulator recognizes to be sound judgment. By contrast, advising an angry friend to avoid making snap judgments before cooling off is not acting manipulatively, if you know that your friend’s judgment really is temporarily unsound.

The Manipulator Knows That He Tricks When He Tricks

Suppose that Amy just left an abusive-yet-faithful partner, but in a moment of weakness she is tempted to go back to him. Now imagine that Amy’s friends employ the same techniques that Shakespeare’s Iago used on Othello. They manipulate Amy into (falsely) believing – and being outraged – that her ex-partner was not only abusive, but unfaithful as well. If this manipulation prevents Amy from reconciling, she might be better off than she would have been had her friends not manipulated her.

Beneficial 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.

We Are Constantly Subject To Attempts At Manipulation

Perhaps manipulation is wrong because it harms the person being manipulated. Certainly, manipulation often harms. If successful, manipulative cigarette ads contribute to disease and death; manipulative phishing and other scams facilitate identity theft and other forms of fraud; manipulative social tactics can support abusive or unhealthy relationships; political manipulation can foment division and weaken democracy. But manipulation is not always harmful.

Is Manipulation Wrong Because It Harms?

Yet, to many, Amy’s friends’ manipulation could still seem morally dodgy. Intuitively, it would have been morally better for her friends to employ non-manipulative means to help Amy avoid backsliding. Something remains morally dubious about manipulation, even when it helps rather than harms the person being manipulated. So harm cannot be the reason that manipulation is wrong.

No, Manipulation Is Not Wrong Because It Harms. 

It appears, then, that whether an influence is manipulative depends on how it is being used. Iago’s actions are manipulative and wrong because they are intended to get Othello to think and feel the wrong things. Iago knows that Othello has no reason to be jealous, but he gets Othello to feel jealous anyway. This is the emotional analogue to the deception that Iago also practises when he arranges matters (eg, the dropped handkerchief) to trick Othello into forming beliefs that Iago knows are false.
