Gaslighting: what it actually is, and how to spot it

Why it's different from a normal disagreement

In a normal disagreement, two people remember or interpret something differently and work from there; gaslighting specifically targets your ability to trust your own memory or perception, which is a different kind of damage than just being wrong about a fact.

The phrases that do the actual work

Lines like 'that never happened,' 'you're too sensitive,' or 'you're remembering it wrong' aren't really about the specific event — repeated often enough, they train you to check your own perception against someone else's version before trusting it.

Why it works better on people who already doubt themselves

Gaslighting tends to land hardest on people who already have some baseline uncertainty about their own judgment, which is why it can escalate slowly — each successful instance makes the next one easier to pull off.

The habit that starts to undo it

Writing things down close to when they happen — what was actually said, how you actually felt — gives you a record to check against later, which matters because gaslighting depends on your memory being the only, and therefore challengeable, version.

This describes a pattern to recognize, not a clinical diagnosis of any specific person — if you consistently find yourself unsure of your own perception around one particular person, a therapist can help you sort out what's actually happening.
