Gaslighting

What it is

Making someone question their own perception of reality through persistent denial and contradiction.

How it works

By repeatedly denying events, contradicting memories, and trivializing feelings, the manipulator erodes the target's confidence in their own judgment, creating dependency on the manipulator's version of reality.

Real-world examples

•"That never happened, you're imagining things" in personal relationships.
•A manager denying they gave specific instructions that led to failure.
•Rewriting shared history to make the victim doubt their memory.

Historical case studies

The original Gaslight film

1944Film / Psychology

In the film that named the technique, a husband systematically dims the gaslights and denies the change when his wife notices. The film became the clinical reference for reality-distortion abuse.

Theranos corporate culture

2014–2018Business

Elizabeth Holmes reportedly told employees who raised concerns about faulty blood tests that they were wrong, incompetent, or not committed enough. Internal dissent was pathologized rather than addressed.

Soviet psychiatric abuse

1960s–1980sPolitics

The Soviet Union diagnosed political dissidents with "sluggish schizophrenia" and institutionalized them. Disagreement with the state was literally reframed as mental illness — gaslighting at institutional scale.
