Paula has come to believe her husband, Gregory, is having an affair, but all she has to go on is intuition. When she confronts him, he responds with a well-stocked arsenal of comebacks. First hurt, then indignation that she has so little faith in him. Next a healthy dose of reassurance, followed by a diagnosis: he traces her suspicion to the childhood trauma of her own father’s infidelity. Each response assuages her doubt only momentarily, and she can’t help raising the matter again. This time Gregory mocks her, demanding she produce evidence. Finally, he explodes, telling her he’s sick and tired of her nonsense, that he’s been patient, but his patience is wearing thin. Throughout the ordeal he plays her like a harp, plucking the strings of guilt, shame, doubt, and fear, framing her suspicion, again and again, as pathology. Paula internalizes the verdict and turns her doubts about him into doubts about herself. She eventually concludes she is suffering from a bad case of paranoia and asks her therapist to help her “fix” her suspiciousness. The therapist declines the assignment and suggests a private investigator instead, which settles the matter in short order. There is nothing left for Gregory to do. He’s been caught red-handed.
It’s both a relief and a small vindication to discover, once and for all, that your husband has been pulling the wool over your eyes. Everything falls into place—the inconsistencies, the too-ready explanations. He wanted things to go his way, so he lied, and in lying turned your sense of reality into a matter he alone gets to determine. You knew what you saw. You knew what you sensed. And still you found yourself doubting it, right up until you didn’t. It’s an all too familiar story.
Our understanding of human nature grows in step with the emergence of new terms that finally pin a name on a long-recognized pattern. In a previous post we discussed one such term: mansplaining. Gaslighting is another. Most people have heard it and use it without a second thought. In 2022, Merriam-Webster named it word of the year, citing a seventeen-fold spike in searches. It has migrated into everyday conversation, political commentary, social media, therapy, and journalism—evidence of a genuine cultural phenomenon, not a passing fad. Though the behavior is gender-neutral in principle, in practice it’s disproportionately attributed to men.
The term’s origin is less widely known. It comes from a 1944 film of the same name, in which a husband tries to drive his new bride mad by tampering with her sense of reality. He dims the gas-powered lights, then insists, when she remarks on the change, that nothing has changed. It’s one maneuver among many aimed at convincing her—and eventually the world—that she’s losing her mind, so he can have her committed and search the walls of their house for jewels he believes are hidden inside them.
Gaslighting is defined as a sustained campaign to make another person doubt the testimony of their own senses and memory. It requires outright deception: the gaslighter knows the truth but promotes an “alternate” version of reality (sound familiar?)—better known as a lie. It helps him cover his tracks, dodge the consequences of his actions, and get another person to accept his version of reality, which advances his agenda.
I first encountered the clinical term nearly fifty years ago, at a psychiatric meeting outlining the features of gaslighting and the traits that make a person susceptible to falling sway to its effects. The case presentation involved a man who, after admitting to his wife he’d had an affair, blamed her for it: he’d explicitly warned her that if she didn’t become more sexually responsive, he’d look elsewhere. She had no memory of any such warning, which she found disconcerting—his claim played on her pre-existing tendency to doubt herself, and he knew it. Things clarified only once he admitted his “warnings” had been vague at best, and quite possibly nonexistent.
The term gaslighting remained relatively obscure until it appeared in the title of Lauren Duca’s 2016 Teen Vogue essay “Donald Trump Is Gaslighting America.” That essay, which drew over a million readers, extended a concept traditionally used to describe one-on-one psychological abuse into the realm of politics. Duca argued that Trump was not merely making false claims but employing a broader strategy of repeatedly denying observable facts and encouraging his supporters to distrust independent sources of information—one she worried would erode confidence in the very idea of objective evidence.
Another cultural moment arrived two years later, on the U.K. reality show Love Island. Two contestants, Adam Collard and Rosie Williams, had forged a romantic bond. When a new female contestant arrived, Adam shifted his attention entirely in her direction. Rosie felt hurt and told Adam as much; Adam pushed back, recasting her hurt as drama, discounting the significance of his own actions, and charging her with misreading the situation out of insecurity and jealousy. Women’s Aid, a leading British domestic-abuse charity, took the unprecedented step of issuing a public statement calling out Adam’s behavior, noting that he had questioned Rosie’s memory, trivialized her feelings, and turned the blame back on her. The organization named it “gaslighting,” and searches for the term surged as the episodes aired, spreading it into newspapers and everyday British vocabulary.
Let’s consider some classic examples, starting with con artists, who gaslight by trade. Bernie Madoff is instructive: when one of his largest clients was rattled by a skeptical Barron’s article about the legitimacy of Madoff’s operation, Madoff invited him in for a demonstration—a small piece of theater. He let the man pick any stock from a screen of supposed holdings, the way a magician fans a deck of cards. “Pick one, any one.” The man picked AOL Time Warner. Madoff pulled up what looked like a live feed from Wall Street’s clearing house, confirming the position down to the letter. It was fabricated—an employee down the hall was typing the “live” data by hand. The client left satisfied, having seen it “with his own eyes,” which is precisely the point: a sufficiently convincing show of proof can override perfectly sound suspicion.
Another classic appears in Hans Christian Andersen’s “The Emperor’s New Clothes,” the tale of two swindlers who promise the emperor a magnificent garment, then deliver nothing—but build in an escape hatch, announcing that only fools will fail to see the fabric. Shame does the rest of the work: the emperor looks, sees nothing, and says nothing, for fear of confirming himself the fool. Conning, the threat of shame, and gaslighting overlap here like circles in a Venn diagram, each reinforcing the others to keep the mark compliant.
It’s worth distinguishing gaslighting from its look-alike, self-deception. A man who lies to himself and buys his own bullshit isn’t gaslighting anyone, even if the effect on those around him looks similar, because gaslighting, properly defined, requires that the deceiver knows the truth. The self-deceiver’s motive isn’t conquest but self-protection: he can’t afford to want what he suspects he won’t get. Confusing the two flattens a useful distinction into a blunter, less accurate one.
The usage of the term itself deserves scrutiny. “You’re gaslighting me” is a loaded accusation, typically delivered with total conviction. Charging someone with gaslighting effectively discredits anything they say thereafter—leaving us to wonder who’s gaslighting whom? The accusation can also function as a conversation-stopper: if every challenge to my version of events counts as gaslighting, my version becomes unfalsifiable, and I’ve claimed a kind of immunity from being wrong. A term coined to name one manipulation tactic has, in diluted form, become a manipulation tactic of its own.
There’s a related wrinkle: the term oftentimes is applied too loosely, to any disagreement over differing accounts of an event or what it meant to the two parties involved. Two people sincerely remembering an argument differently isn’t gaslighting—it just reflects the imperfection of memory and the often-indeterminable nature of reality.
So how do you tell the real thing from the buzzword? Paula’s story is, in the end, a decent field guide. Genuine gaslighting doesn’t announce itself in a single exchange; it shows up as a pattern—a rotating cast of tactics (hurt, reassurance, diagnosis, mockery, rage) that all point away from the substance of the complaint and toward the complainer’s supposed instability. It survives contact with evidence by discrediting whoever produces the evidence, and it tends to unravel the moment someone outside the relationship—a therapist, an investigator, a friend with no stake in the outcome—looks at the facts without the gaslighter’s narration running underneath them. Ordinary disagreement doesn’t behave that way. Ordinary disagreement can usually survive being looked at.
Paula didn’t need a diagnosis to know something was wrong; she needed permission to trust what she already knew. That, more than any definition, may be the real test: not whether you can prove it, but whether you’re finally allowed to believe your own eyes.
