The Brief: Gaslighting is a tactic intended to gain power by manipulating someone and making them question the validity of their experiences, point of view, and/or perspective.

DEEP DIVE
Gaslighting is when an individual poses a question or comment that is intended to manipulate someone and make that individual question the validity of their experiences, point of view, and/or perspective. This tactic is meant to gain power, according to Psychology Today.
The term originated from a 1938 British play called Gas Light. In the United States it was known as Angel Street. The 1940 and 1944 film adaptations were both titled Gaslight. The film follows a man who manipulates his wife to the point where she thinks she is insane.
