Triangulation

What it is

Bringing a third party into a two-person dynamic to manipulate, control, or create jealousy.

How it works

By introducing a third person into a relationship dynamic — whether through comparison, competition, or as a messenger — the manipulator creates insecurity and rivalry. This destabilizes the target's confidence and makes them work harder to win the manipulator's approval.

Real-world examples

  • •A manager telling an employee "Your colleague would jump at this opportunity" to pressure compliance.
  • •A romantic partner frequently mentioning an attractive ex to create jealousy.
  • •A parent playing siblings against each other: "Why can't you be more like your brother?"

Ethical guidelines

  • ●This technique is inherently unethical and psychologically harmful. Never use it in any context. If you recognize yourself doing this, seek professional help.
  • ●Communicate directly with each person rather than using intermediaries strategically.
  • ●Do not create artificial competition to control people.
  • ●Comparison should motivate, not destabilize.

How to defend against it

  • ►If this is happening in a relationship where you are afraid of the other person, treat your safety as the first priority: talk to a domestic-violence advocate or hotline before confronting, documenting, or leaving — those steps can escalate risk when done without a plan.
  • ►Recognize when a third party is being used to pressure you.
  • ►Refuse to compete for approval — state your boundaries directly.
  • ►Ask: "Is this comparison relevant, or designed to make me insecure?"

From the Defense Playbook

Perspective-Getting, Not Perspective-Takingminutes

To understand what another person thinks or wants, ask them and listen, instead of imagining yourself in their shoes; imagining feels insightful but in controlled tests does not improve accuracy, while asking does.

Superordinate Goals and Structured Contacttakes practice

Reduce hostility between groups by having them work together, as equals, toward a goal that both want and neither can reach alone; mere exposure or exhortation does little, but cooperative contact under the right conditions reliably lowers prejudice.

Grey Rocktakes practice

When you cannot avoid contact with someone who feeds on your reactions, make your responses brief, factual, and emotionally flat so that provoking you stops being rewarding; this is a folk practice from survivor communities, not a researched intervention.

"Why Do You Ask?"seconds

Answer an intrusive, oddly specific, or out-of-place question with a friendly question of your own about its purpose, which buys time, reveals intent, and breaks the reflex to answer simply because you were asked.

Every playbook entry states how strong its evidence is and when not to use it. Browse the full playbook.
