Gaslighting or an ordinary disagreement?

Gaslighting takes its name from a 1938 play and its film adaptations, in which a husband dims the gas lamps and then denies that the light has changed, in order to make his wife doubt her own mind. In its original and most useful sense it means a pattern of behaviour that undermines another person's confidence in their own perception, memory or judgement — so that over time they rely on the gaslighter's version of reality instead of their own.

Philosopher Kate Abramson describes the aim precisely: not to win a particular argument, but to undermine the other person's standing as someone whose view of things counts at all. Sociologist Paige Sweet adds that gaslighting works best where there is already an imbalance of power — and where stereotypes ("you're so emotional", "you're imagining it") are available to lend the denial credibility.

The word has become so common that it is now applied to almost any disagreement about what happened. That dilution matters, because it makes it harder to name the real thing when it occurs — and easier to accuse an honest partner of manipulation.

Observable behaviours people describe. Watch for the pattern, not the one-off.

• Flat denial of verifiable events. "I never said that" — about something in a message you can scroll back to.
• Reframing your reaction as the problem. "You're too sensitive." "You always twist things." The topic shifts from what happened to what is wrong with you.
• Confident retelling. Their version is delivered with certainty and detail; yours is treated as confused.
• Recruiting others. "Everyone thinks you overreact." Third parties are invoked, often without their knowledge.
• Selective amnesia in one direction. They forget their own hurtful behaviour reliably, and remember yours in detail.
• The effect on you. You start recording conversations in your head, apologising for things you are not sure you did, and checking your perception with them before trusting it.

Several very different mechanisms produce "that never happened". Hold more than one in mind.

1. Ordinary reconstructive memory. Decades of research — notably Elizabeth Loftus's work on the misinformation effect — show that memory is not a recording. People sincerely and confidently remember events that did not happen as remembered, and two honest people frequently recall the same conversation differently. This is the most common explanation for a single disagreement.

2. Defensive self-protection. Admitting "I said that and it was unkind" costs something. Some people, under shame or threat, reach for denial reflexively — not to control you, but to protect themselves. This can still be corrosive if it is never repaired.

3. Conflict-avoidance and stonewalling. Some people deny or minimise to end a conversation they find overwhelming. It feels like gaslighting from the receiving end; the motive is escape rather than domination.

4. Deliberate undermining. And some people — consistently, across many events, and in one direction — deny what you can verify, recast your perception as a defect, and benefit from your growing dependence on their account. This is gaslighting in the full sense. A 2023 qualitative study of 65 survivors found it typically occurred within a cycle of affectionate and abusive behaviour, and left people with a diminished sense of self and increased mistrust of others.

These steps protect your sense of reality whatever the explanation turns out to be.

1. Write things down, close to the time. A brief dated note — what was said, by whom — is the single most useful habit. It makes honest memory disagreements easy to resolve and dishonest ones visible.
2. Keep messages. Do not delete threads in anger. Verifiable records are how you distinguish "we remember differently" from "they deny what is written".
3. Separate the event from the interpretation. "You said Saturday works" is an event. "You don't care about my family" is an interpretation. Argue the first; discuss the second.
4. Ask for a repair, not a verdict. "We remember this differently and it matters to me. Can we agree to check messages before we argue about who said what?" A good-faith partner can accept this. Watch what happens when you propose it.
5. Keep outside reference points. Friends, family, a therapist, a diary. Isolation is the condition in which a single person's version of reality becomes the only one available.
6. Track the direction. Over a month, note whether the "misrememberings" favour one person. Symmetry suggests memory; asymmetry suggests something else.

When your memory is denied:

"We clearly remember this differently. I'm not going to argue about who's right — but I do want to find out, so let's look at the messages together."

When the subject shifts to what is wrong with you:

"Maybe I am sensitive about this. That's a separate conversation. Right now I want to stay on what was said on Tuesday."

When you need to hold your perception without escalating:

"I hear that you don't remember it that way. I'm going to trust my own notes on this one, and I'd rather we move on than keep going round."

Proposing a repair:

"This keeps happening and it's wearing on both of us. Could we agree that when we disagree about what was said, we check rather than argue?"

Each line states what you observed, declines the invitation to debate your sanity, and offers a way forward. The response you get is more informative than the original disagreement.

Seek support sooner rather than later if:

• You have begun to doubt your perception in general, not just about specific events.
• You routinely check your memory with the other person before trusting it.
• Denials extend to things you have in writing, repeatedly and in one direction.
• Friends or family have become "the problem", and you see them less.
• The pattern sits alongside monitoring, financial control, threats or fear.

Gaslighting as part of a wider pattern of control is recognised in law: in England and Wales, controlling or coercive behaviour in an intimate relationship is a criminal offence (Serious Crime Act 2015, s. 76). In Spain, the 016 service provides free, confidential support.
