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, adapted from Patrick Hamilton's 1938 play, gave its name to reality-distortion abuse.

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.

Ethical guidelines

  • ●This technique is inherently unethical and psychologically harmful.
  • ●Never use gaslighting in any context.
  • ●If you recognize yourself doing this, seek professional help immediately.

How to defend against it

  • ►Keep written records of important conversations and events — stored somewhere the other person cannot access (a locked notes app, a friend's email, a separate cloud account). If you are in an active abusive situation, your safety comes before documentation; consult a domestic-violence professional before creating records the abuser might discover.
  • ►Trust your own memory and feelings as valid data points.
  • ►Confide in trusted third parties to reality-check your experience. In severe cases, work with a therapist trained in coercive control rather than a general counselor — the specialization matters.
  • ►If a relationship, workplace, or family dynamic is regularly making you doubt basic reality, that pattern itself is diagnostic information regardless of any single incident.

From the Defense Playbook

Write It Down (Externalize the Decision)minutes

Move the claims, numbers, promises, and your own reasoning out of your head and onto paper or a file, where they cannot be re-described, forgotten, or overloaded.

Safety Planning Firsttakes practice

If you are afraid of a partner, ex-partner, or family member, plan for safety with a trained domestic-violence advocate before you confront, disclose, change your routines, or leave, because those are the moments when the risk of serious harm is highest.

Documentation, Kept Safelytakes practice

Keep a dated, factual record of incidents, messages, and transactions so that your memory and your account cannot be rewritten, and store it only where the other person cannot find or reach it, because your safety comes before any record.
