Gaslighting
What gaslighting means, where the word came from, how it differs from an honest disagreement, and what may help if you keep doubting your own memory.
Key takeaways
- Gaslighting is a repeated pattern of making someone doubt their own memory, perceptions or sanity, not a single lie or disagreement.
- The word comes from the 1938 play Gas Light and the 1944 film Gaslight, in which a husband secretly dims the lamps and insists his wife is imagining it.
- Sociologist Paige Sweet's 2019 research found gaslighting is most damaging when it draws on stereotypes and other forms of control in a relationship.
- Keeping a private, dated record and talking with someone outside the relationship can help steady your sense of what happened.
- Where gaslighting comes with threats, control or fear, individual support and the National Domestic Violence Hotline are safer first steps than couples therapy.
What does gaslighting mean?
Gaslighting describes a pattern, not a single moment. One person repeatedly tells another that what they saw, heard or felt did not happen, or did not happen the way they remember. Over time the person on the receiving end starts checking their own mind before trusting it. The National Domestic Violence Hotline describes gaslighting as a form of emotional abuse that leaves someone doubting their perceptions, memory and even their sanity.
In everyday speech the gaslighting meaning has stretched to cover almost any lie or argument. That broad use can blur the concept, so this entry keeps to the narrower sense: a repeated tactic inside a relationship where one person gains power by making the other feel unreliable.
Where the word came from
The term traces back to Gas Light, a 1938 stage play by Patrick Hamilton, best known through George Cukor’s 1944 film Gaslight starring Ingrid Bergman and Charles Boyer. In the story, a husband dims and brightens the gas lamps in the house, then insists his wife is imagining the change, as part of a plan to make her believe she is losing her mind. Sociologist Paige Sweet notes that psychotherapists later popularized the word as shorthand for this kind of crazy-making.
Gaslighting is a descriptive term, not a diagnosis. In a 2019 study in the American Sociological Review, Sweet conducted life story interviews with 43 women attending domestic violence support groups, and nearly all described partners trying to make them feel “crazy.” She argued that gaslighting works best when it leans on stereotypes, such as the idea that women are overly emotional, and on other forms of control.
Gaslighting examples
These short illustrations are composites, not real people:
- Denying events. “I never said that. You’re making things up again,” about a conversation you clearly remember.
- Countering memory. “That’s not how it happened. You always get the details wrong.”
- Trivializing feelings. “You’re too sensitive. Nobody else would be upset by this.”
- Diverting. Turning every concern you raise into a conversation about your “paranoia.”
- Recruiting others. “Even your sister thinks you’ve been acting unstable.”
Picture someone sitting in a dark kitchen in Grand Rapids at midnight, scrolling back through old texts just to prove to herself that a conversation really took place. That habit of gathering evidence against your own doubt is one of the signs people describe most often.
Gaslighting or an ordinary disagreement?
| Ordinary disagreement | Gaslighting |
|---|---|
| Both people remember differently and say so | One person insists the other’s memory or perception is defective |
| Either partner may turn out to be right | The same person is always “right” |
| Feelings are taken seriously even when facts differ | Feelings are dismissed as overreaction or instability |
| You leave frustrated but still feeling like yourself | You leave confused and less sure of your own mind |
Honest people misremember things all the time, and two partners can recall the same evening differently. The difference lies in direction and effect. Gaslighting moves consistently one way and leaves one partner increasingly dependent on the other’s version of reality.
How it shows up in couples and families
Between partners, gaslighting often travels with other tactics such as DARVO, isolation from friends and the wider pattern known as coercive control. In families, a parent may insist that painful events “never happened,” which can make it harder for that child to trust their own perceptions years later. Naming the behavior is not the same as diagnosing the person doing it. What matters is the pattern and its effect on you.
What may help
- Write down events soon after they happen, with dates, somewhere private and secure.
- Talk with a friend or relative who knows you well and can reflect your experience back.
- Notice your body. Persistent confusion, dread or second-guessing is worth taking seriously.
- Let go of winning the argument about what happened. The pattern rarely ends because the other person is shown proof.
Safety, and when a therapist may help
If gaslighting is part of a wider pattern of control, threats or fear, couples therapy is generally not recommended, because honesty in a joint session can lead to retaliation at home. Individual therapy can be a safer place to rebuild trust in your own perceptions. The National Domestic Violence Hotline (1-800-799-7233, thehotline.org) is free and confidential, and an advocate there can help you build a safety plan. If you are in crisis or thinking about harming yourself, call or text 988. When both partners feel safe and the problem is milder, a therapist can help you work through trust issues and patterns of emotional manipulation without anyone being labeled.
Common questions
What is gaslighting in simple terms?
Gaslighting is when someone repeatedly makes you doubt your own memory, perceptions or feelings so that you rely on their version of events instead. It usually involves denying things that happened, insisting you remember wrong or calling you too sensitive. A single disagreement is not gaslighting; the term describes a persistent pattern that shifts power toward one person.
What are examples of gaslighting phrases?
Common examples include "That never happened," "You're imagining things," "You're too sensitive," "You always twist my words" and "Everyone agrees you've been acting crazy." Any of these can be said innocently once. They become gaslighting when they are used again and again to dismiss your experience and leave you doubting yourself.
Is gaslighting a form of abuse?
When it is repeated and used to control or confuse a partner, gaslighting is widely recognized as a form of emotional abuse, including by the National Domestic Violence Hotline. Research by sociologist Paige Sweet found it often appears alongside other controlling tactics. If you feel afraid, the Hotline (1-800-799-7233) can help you think through options and safety.
How do I know if I'm being gaslighted or if I'm just wrong?
Everyone is wrong sometimes, so look at the pattern. If the same person is always right, your feelings are routinely dismissed and you feel less sure of your own mind over time, that points toward gaslighting. Keeping dated notes and checking your experience with a trusted friend or an individual therapist can help you see more clearly.
