"The Gaslight Effect" (book by Robin Stern)

"The Gaslight Effect," by Robin Stern, describes a psychological manipulation tactic where one person subtly convinces another that their perceptions, feelings, or sanity are invalid or mistaken. This often occurs in unhealthy relationships, leading the victim to doubt themselves, feel confused, and become more dependent on the manipulator. The term originates from the 1944 film *Gaslight* and highlights how manipulators distort reality to maintain control. Recognizing the gaslighting effect helps individuals regain confidence, trust their perceptions, and seek healthier interactions.
