What does gaslighting mean?

Gaslighting is the act of distorting the truth in a way that’s intended to make another person accept the deception due to doubting their own memory, reality, or sanity. It’s considered a form of psychological manipulation or emotional abuse.

The verb form is gaslight, as in Don’t try to gaslight me—I have proof of what you’ve done! 

The term gaslighting is often applied in the context of emotionally abusive relationships, such as romantic relationships or among family members. It is also sometimes used in reference to manipulative deception in other contexts, such as by politicians.

When the deception of the person who is engaging in gaslighting is questioned, they often react by dismissing the accusation as a delusion, an emotional reaction, or an overreaction—thus conditioning the person to internalize those assessments. According to mental health professionals, those targeted with gaslighting may experience lowered emotional intelligence and self-esteem due to frequently second-guessing their own judgment and sanity.

In addition to its narrow use in reference to a specific pattern of manipulative and deceitful behavior, gaslighting is also sometimes used more broadly to refer to other different forms of deception, including propaganda, disinformation, and even basic lying.

Example: It can be hard to believe how people can fall prey to such deception, but gaslighting has a very powerful effect.

Where does gaslighting come from?

teal text on dark blue-green background, "gaslighting"

The word gaslighting (referring to the act or practice) comes from the verb gaslight. Both gaslighted and gaslit are used as the past tense of gaslight.

The verb gaslight comes from the 1938 play Gas Light by Patrick Hamilton, which also had two 1940s movie adaptations. In the story, a husband attempts to drive his wife insane by, among other things, dimming the gas lights in their house and claiming she is imagining it.

The first records of the use of the term gaslight in the context of psychology come from the early 1960s. By the 1990s, the term gaslight had gained more casual use outside of psychology, usually in the context of abusive relationships or political rhetoric.

Be cautious of these signs of gaslighting

Be wary of someone who:

  • denies your memory of events, even when presented with proof
  • reinterprets events to shift blame on you
  • minimizes your concerns or feelings
  • makes you question your own version of events
  • lies blatantly

Gaslight and gaslighting gained more widespread, mainstream use in the later 2010s, when such terms were often applied by political commentators and critics to the rhetorical tactics of Donald Trump, both when he was a presidential candidate and during his presidency. Such criticisms often focused on Trump’s use of the term fake news to refer to established facts as a way of presenting a false narrative to the American public.

This frequent use of gaslighting in reference to Trump likely played a role in the broader, more general use of gaslighting to refer to other forms of deception. Some people object to this broader use, especially when gaslighting is used in place of simpler terms, such as lying.

The term gaslighting was commonly used by the media during the Trump presidency and was used by the US government to describe Russia’s propaganda and disinformation strategy during Russia’s 2022 invasion of Ukraine.
