What is gaslighting in simple terms?
It is when someone repeatedly makes you doubt your own memory or perception — insisting things you clearly remember did not happen, or that you are overreacting — until you stop trusting your own judgement.
Where does the word gaslighting come from?
From "Gas Light," a 1938 play by Patrick Hamilton later made into films. A husband secretly dims the gas lamps in the house and tells his wife she is imagining the change, part of a wider campaign to convince her she is losing her mind.
Is gaslighting always deliberate?
The term normally implies intent — a sustained attempt to distort someone else's sense of reality. People do sometimes dismiss others' experiences carelessly rather than calculatedly, and using "gaslighting" for any disagreement waters the word down.
