Where the term comes from

Lexicographic: Merriam-Webster carries an entry. The word's origin, in a 1938 play and the films based on it, is cited below.

Whose definition this is

The one-line summary above is ours. The definition it compresses comes from a named source, quoted in full and linked below — where the two differ, the source is what counts. Everything else on this page that states a fact is sourced.

Contested usage: "Gaslighting" is now used very loosely, often to mean any disagreement about what happened. This page uses the narrow sense quoted below — sustained manipulation aimed at someone's confidence in their own perception — and the loose usage is worth resisting, because it makes the word useless for the thing it was needed for.

Merriam-Webster defines gaslighting as psychological manipulation of a person, usually over an extended period, that causes the victim to question the validity of their own thoughts and their perception of reality. [1]

Note what that definition includes and what it does not. It is sustained, it concerns perception of reality rather than the facts of one dispute, and its effect is on confidence rather than on the argument.

The word carries that shape because of where it came from. [2] The original is a story about someone being made to distrust their own senses — not about being contradicted, and not about losing an argument.

The online version

Online it usually shows up in a narrower form than the clinical one, and the distinction matters.

A message is edited and the earlier version denied. A statement made in front of dozens of people is described as something you invented. Your objection is recharacterised as an overreaction, then your reaction to that is offered as proof you were overreacting all along. Each step is deniable, and the record — if there still is one — is a screenshot you now have to produce like evidence.

The effect that matters is not losing the argument. It is the half-second of genuine uncertainty about whether you remember your own week correctly.

Recognising it

  • Flat denial of things that were said in public, where a record exists
  • Your reaction becoming the subject, repeatedly, in place of the thing you reacted to
  • Edits, deletions, and then confident accounts of what was "actually" written
  • A pattern across time rather than a single contested exchange

The honest difficulty

Of every term on this site, this is the one most likely to be applied to something innocent, and the cost of getting it wrong is high in both directions.

Two people can remember the same conversation differently and both be telling the truth. Memory is reconstructive, arguments are stressful, and a person who is genuinely certain you said something you did not say is not manipulating you — they are wrong. That is not a rare edge case; it is the ordinary condition of disagreement, and it looks identical to the tactic from inside a single exchange. Someone defending themselves against an accusation they believe is unfair will also, quite naturally, dispute your account of what happened. That is what disputing an accusation is.

The definition above is doing real work here, and it is worth reading twice. It turns on manipulation sustained over time, aimed at your confidence in your own perception. Not one contested recollection. Not being contradicted firmly. Not someone being certain and wrong. The thing that distinguishes it is that the target of the effort is your judgement itself rather than the point in dispute — and that you can only see across a stretch of time, never in one message.

The reason to hold that line is not pedantry. Applying the word to an ordinary argument does two kinds of damage: it puts a serious accusation on someone who has not earned it, and it spends the word, so that the person who genuinely needs it finds it has been worn down to mean "we disagreed and I was upset". If you are unsure, you are allowed to say the concrete thing instead — "that is not what I said, and here is the message" — which is both more precise and harder to argue with.

What to do

Keep the record, quietly — there is a right way to capture it. Screenshots with timestamps, kept somewhere else. Not to win an argument — to settle the question for yourself, which is the part actually under attack.

Do not litigate your own memory in public. It is the argument you cannot win and the one they benefit from, because every round of it performs uncertainty in front of an audience.

Check with someone who was there. One outside account of the same exchange does more than any amount of re-reading.

If this is happening across your life rather than in one thread, and by someone with ongoing access to you, that is a different situation from an online argument — the support services are the right place for it.

Not the same as

Remembering something differently
Two people genuinely recalling an exchange differently is ordinary and extremely common. Gaslighting is sustained, one-directional, and aimed at your confidence in your own judgement rather than at establishing what happened.
Being wrong
Someone insisting on a version of events you disagree with may simply be mistaken and stubborn. Motive matters here, and motive is hard to read from a single exchange.

Responding at this level

Recognition matters more than response. The tell is the pattern across a conversation, never any single message, and the honest advice is to judge the exchange rather than the sentence.

  • Keeping a record →

    Writing down what happened, when it happened and who saw it — a practice borrowed from guidance about stalking and harassment, not tested for the ordinary tactics documented elsewhere on this site.

  • Don't feed the trolls →

    Declining to reply, so that provocation produces no reaction and no audience. The most repeated advice on the internet, and among the least examined.

Others at this level

  • Sealioning — Relentless, superficially polite demands for evidence that exhaust the target while preserving the appearance of good faith.
  • Concern trolling — Opposing something while posing as a worried supporter of it, so the objection arrives pre-shielded from challenge.
  • Whataboutism — Deflecting a criticism by raising a different alleged wrong instead of answering the one raised.
  • Gish gallop — Burying an opponent under more claims than can be answered in the time available, so unanswered reads as unanswerable.
  • Motte-and-bailey — Advancing a strong contentious claim, then retreating to a modest defensible one when challenged, then returning.
  • DARVO — Deny, Attack, and Reverse Victim and Offender — a documented response pattern that recasts the accused as the wronged party.
