Reptilian brain · Threat Response

Territorial Defensiveness

Hostility triggered when someone encroaches on what you consider yours — a market, a role, a desk, a decision right; the reaction is instinctive and often disproportionate to the actual threat.

An everyday example

Blocking a sensible reorganisation because it moves one report out of your team.

What it can cost you

Fighting for territory instead of for outcomes; predictable buttons others can press.

Warning signs

  • I am angry about a boundary, not a result.
  • Someone knew exactly which boundary to push.

One thing to do

Ask what outcome the territory is for; defend the outcome, trade the territory.
