Gaslighting

You walk out of an argument certain of what was said. An hour later you're not sure anymore — because their version is so confident it overwrites yours. Do that enough times, and you stop trusting your own memory at all.

Gaslighting — what it is

Gaslighting is a pattern where someone makes you doubt your own memory, perception, or sanity by repeatedly insisting your version of events is wrong — until you defer to theirs. The name comes from the 1938 play Gas Light, where a husband dims the lamps and tells his wife she's imagining it.

How to recognize it

One person misremembering a night is normal. Gaslighting is the repeated version, where the doubt only ever runs one way — toward you being wrong. The usual lines:

Why it works. Human memory is reconstructive — it's genuinely editable by a confident outside account, especially from someone you love and trust. Gaslighting exploits that. It doesn't need to win one argument; it needs to run long enough that your default becomes "I'm probably wrong." That last tell — quietly documenting your own life for evidence — is the clearest sign the pattern has taken hold.

The counter-move

You cannot win a debate about reality with someone who edits reality — so stop having it. The move is to anchor reality outside your own head, where it can't be overwritten.
