Gaslighters engage in the manipulation technique of distorting known facts, memories, events and evidence to invalidate a person’s experience. The idea is to make those who disagree with the gaslighter question their ability, memory or sanity. (See it in action in the 1944 movie “Gaslight,” starring Ingrid Bergman and Charles Boyer.)
Gaslighters use lies, false promises and personal attacks to make those around them doubt themselves. For example, at a meeting on Tuesday, your boss says, “You can all leave at noon on Friday.” When Friday comes along, your boss indignantly says, “I would never say you could leave early. You weren’t paying attention.”
When it comes to politics, gaslighting is all around us. Gaslighting also occurs in personal relationships, though it is often subtler, but gaslighting in the workplace can be especially destructive—particularly if your boss is the culprit.
