Understanding Power Dynamics Predicts Behaviour

The Red Liner Model (RLM©) is a conceptual framework – a thought experiment – that
explains why certain interpersonal problems persist despite repeated intervention.

It focuses on patterns, not personalities.

What “Red‑Liner Behaviour” Means (and doesn’t)

Red‑liner behaviour is not a label for a person or personality type.

It describes a pattern of behaviour in which someone:

  • Consistently seeks advantage in interactions
  • Tests and adapts tactics when challenged
  • Uses dismissal, interruption, emotional pressure, or role authority to maintain control

The model is descriptive, not moral.
It exists to support effective response – not blame.

Why “doing the right thing” often makes things feel worse

RLM uses the doors analogy to explain why many interventions fail.

When one behavioural exit is closed, others are tried.

Closing only some doors changes nothing.

This is why first attempts to set boundaries often feel as though they “backfire.”

From understanding to effective response

Building on the Red‑Liner Model, participants learn a Boundary‑Led Response Method.

This approach:

  • Is grounded in pattern recognition
  • Is designed for live, high‑pressure interactions
  • Recognises that some escalation is a phase, not a failure
  • Produces long‑term de‑escalation through consistent, appropriate response

Firm responses to micro‑escalations change outcomes – not immediately, but reliably over time.
