In short
Reactance is the motivational push-back that arises when a person feels their freedom to choose, think or act is being threatened or removed, and that pushes them to restore the freedom by wanting the forbidden thing more, doing it anyway, or resisting the person who issued the threat. It shows up in health campaigns that make the warned-against behavior more tempting, in product bans that create demand, in teenagers and adults alike when a request is phrased as an order, and on the restroom walls of a university in 1976.
How reactance works
Jack Brehm's 1966 theory starts from a simple claim: people believe they have a set of free behaviors, things they could do or choose if they wished, and when one of those freedoms is threatened or removed they experience an unpleasant motivational state aimed at getting it back. That state is reactance. It can be reduced by doing the forbidden thing, by wanting it more, by downgrading the source of the threat, or by exercising some other freedom instead. The theory predicts that reactance grows with the importance of the freedom, with the proportion of freedoms under threat, and with how strongly the threat is worded.
The wording matters because a demand carries two messages. One is the content: do not write on this wall. The other is a statement about the listener: you are someone who can be ordered. A polite request leaves the choice with the reader, and the reader can comply without conceding anything. A command with no exceptions takes the choice away, and the only way to show it is still yours is to use it. In Pennebaker and Sanders's study the strict sign was the one that drew writing, and a signature from a higher authority drew more again.
Later work sharpened what reactance is made of. Dillard and Shen proposed in 2005 that it is best measured as a combination of anger and counterarguing, and Rains's 2013 meta-analysis of 20 studies with 4,942 participants found that this intertwined model fit the data better than anger alone or counterarguments alone. Reactance, on that account, is a hot state with an argument attached: the person feels pushed and starts building the case against the pusher.
Not every claim made in the theory's name has held up. The best-known one, the Romeo and Juliet effect reported by Driscoll, Davis and Lipetz in 1972, in which parental interference supposedly deepened couples' love, was tested again by Sinclair, Hood and Wright in 2014 with the original measures and 396 participants; they found no such effect, and interference went with poorer relationship quality instead. Reactance to a sign is well documented. Reactance as a general law that opposition breeds devotion is not.
The original study
Brehm's 1966 book, A Theory of Psychological Reactance, set out the theory and reported a series of laboratory experiments in which eliminating or threatening a choice made the lost option more attractive. The field study that became the textbook illustration came a decade later. James Pennebaker and Deborah Yates Sanders published "American graffiti: Effects of authority and reactance arousal" in the Personality and Social Psychology Bulletin in 1976.
The setting was the restroom stalls of a university. Placards were posted on the walls with one of two messages. The high-threat version read "Do NOT write on these walls under any circumstances!" The low-threat version read "Please don't write on these walls." Each message was attributed either to a high authority or to a low authority, which gave four combinations. The measure was the graffiti that appeared on the placards themselves. The amount of writing rose with the level of threat in the wording and with the authority of the signer; the paper interpreted the pattern as a response to reactance arousal. The placard that tried hardest to stop the writing was the one that collected the most of it.
Read the diagram and evidence as text
Matched placards forbid the same writing action. The stronger command has an extra prohibition ring; a more emphatic dashed pen route ends in graffiti on that very placard. Scribble geometry stays identical, with weight showing ordering only. The dashed route is a proposed reactance mechanism, not a measured psychological mediator.
“Please don't” versus “Do NOT, under any circumstances!”
Direction only; the paper reported no figure
Command with no exceptions: “Do NOT write on these walls under any circumstances!”
Reactance: The choice feels taken away; a push to show it is still yours
Writing on the placard: Rose with the threat in the wording and with the authority of the signer
Command with no exceptions → freedom threatened → Reactance (error transition)
Reactance → freedom restored by using it → Writing on the placard
| Condition | Value and unit | Evidence quote |
|---|---|---|
| Four placard versions, university restroom stalls | Rose with the threat in the wording and with the authority of the signer amount of graffiti on the placard | the amount of graffiti written on the placards rose with the threat in the wording and with the authority of the signer |
The study has limits worth stating. It was small and brief, graffiti is a low-stakes behavior, and the paper reported the pattern rather than a figure that has entered the secondary literature, which is why the result on this page is given as a direction and not as a percentage. What makes it the standard example is its cleanness: the request was the same in every stall, and only the force behind it changed.
Reviews by Miron and Brehm in 2006 and by Steindl and colleagues in 2015 trace the theory's forty years of experiments, from forced choices between records and films to health messages that tell people what they must do, and find the core prediction holding across them: the harder the push, the stronger the pull back.
Everyday examples
Reactance appears wherever a request is delivered as a removal of choice. The rows below are illustrations, not findings from the studies cited on this page.

| Situation | What the bias does | What helps |
|---|---|---|
| A public health message says you must never do something | The audience feels lectured, argues back, and the behavior holds steady or rises | Give the facts, acknowledge the choice is the reader's, and say what most people choose |
| A parent forbids a particular friend or band | The forbidden thing acquires the glamour of the forbidden and the argument becomes about control | Explain the concern once, then leave the decision visibly open where it safely can be |
| A manager issues a rule with no exceptions and no reason | Staff follow the letter while finding ways around the spirit | State the reason, invite objections, and allow the exceptions that the reason permits |
| A product or book is banned | Demand rises and the ban becomes the best advertisement | Make the case against it and let people decide; a ban hands the argument to the other side |
| A salesperson says this offer ends in ten minutes | Some buyers rush, and others walk away precisely because they are being pushed | Decide the purchase as if the deadline did not exist; if it is a good buy today it was a good buy yesterday |
How to counter it
Reactance is a response to how a message is framed, so the counters work on both sides: how you issue requests and how you hear them.
- When asking, leave the choice visible. A request that ends by acknowledging that the other person can say no asks for the same thing as a demand without taking anything away, which is the mirror image of the graffiti result.
- Give the reason with the rule. A reason turns a command into information the listener can weigh, and information does not threaten a freedom.
- Scale the force to the stakes. Absolute language, never and under any circumstances, invites the test of the exception. Save it for things that are actually absolute.
- When you feel the push-back, name it. The urge to do the opposite of what you have just been told is not evidence that the opposite is a good idea; it is evidence that you were told.
- Separate the message from the messenger. Ask whether you would want the forbidden thing if nobody had forbidden it. If not, the wanting is reactance and will pass.
- Recognize reactance being used on you. Marketing that tells you that they do not want you to know this, or that you cannot handle it, is renting your resistance.
What it is not
Reactance is a specific motivational state with a specific trigger: a perceived threat to a freedom. Several neighbors are easy to confuse with it.
- It is not reverse psychology, which is a tactic rather than a response: a person tells you to do the opposite of what they want, counting on your reactance to deliver the result. Reactance is what the tactic exploits.
- It is not the backfire effect, in which a correction supposedly strengthens the belief it was meant to fix. That claim concerns factual beliefs and has replicated poorly; reactance concerns freedom of action and the wording of demands.
- It is not status quo bias, the preference for the way things are. Reactance can push toward change or against it; what it opposes is the removal of the choice.
- It is not simple defiance or a personality trait, though people differ in how readily they experience it. In Brehm's theory anyone with a freedom to lose can feel it, and the same person will feel more of it when the freedom matters more and the threat is heavier.

Reactance FAQ
What is reactance in psychology?
Reactance is the motivational state that arises when a person feels a freedom to choose, think or act is being threatened or taken away, and that pushes them to restore it, often by wanting the forbidden option more or doing it anyway. Jack Brehm proposed the theory in 1966. The classic field demonstration is Pennebaker and Sanders's 1976 study, in which a sign ordering people not to write on a restroom wall collected more graffiti than a sign asking them politely.
What is an example of reactance?
A restroom placard reading Do NOT write on these walls under any circumstances draws more writing than one reading Please don't write on these walls, which is what Pennebaker and Sanders found in 1976. Outside the laboratory, product bans that raise demand, health messages that make a warned-against habit more appealing, and rules with no stated reason that staff quietly route around all show the same shape: the force of the demand, not its content, produces the push-back.
How does the demo on this page work?
When the page loads it assigns you one of two signs, strict or polite, using a value kept only in your browser's session storage so that a reload shows the same version. You rate your urge to write on the wall, and the result screen shows the other sign in full. Once each version has 50 or more answers the page shows the split side by side. The demo measures a self-reported urge in an imagined scene, not behavior, so it illustrates the 1976 result rather than replicating it.
Is reactance the same as reverse psychology?
No. Reactance is the response: the push-back a person feels when a choice is being taken from them. Reverse psychology is a tactic that exploits that response by asking for the opposite of what the asker wants. The tactic only works to the extent that the target experiences reactance, and it fails with people who do not, or who see what is being done. The two have separate pages on this site.
Does reactance explain the Romeo and Juliet effect?
The effect itself is doubtful. Driscoll, Davis and Lipetz reported in 1972 that couples who faced more parental interference reported more love over six months and explained it through reactance. Sinclair, Hood and Wright repeated the study in 2014 with the original measures and 396 participants and found no such effect; interference went with poorer relationship quality. Reactance to a direct demand is well supported. Reactance as a reason that opposition deepens love is not.
How do you reduce reactance when you need someone to do something?
Leave the choice visible and give the reason. A request that acknowledges the person can decline asks for the same thing as a demand without removing a freedom, and a stated reason turns an order into information. Match the force of the wording to the stakes, avoid absolutes unless they are real, and acknowledge the other person's position before stating your own. Dillard and Shen's work suggests that reactance combines anger with counterarguing, so lowering the anger and giving fewer things to argue against both help.
