The Amygdala Hijack
Sometimes you don't have a reaction — a reaction has you. Daniel Goleman coined a name for it: the amygdala hijack, when the brain's alarm system seizes the controls before your judgment gets a vote.
The brain's threat circuitry evolved to act first and check later. When something reads as danger — a sharp email, a public challenge, a dismissive tone — the alarm fires in a fraction of a second, flooding the body with stress hormones before slower, more deliberate thinking weighs in.
Under that flood, thinking narrows. You fixate on the threat, options shrink toward fight, flee, or freeze, and you become briefly, sincerely convinced that the aggressive reply is both justified and urgent. It is neither. It is chemistry.
The hijack can't be prevented — it is wiring, not weakness. But it can be recognized. The surge peaks and starts fading within minutes if you don't refuel it, and every hijack has tells you can learn: heat in the face, a tight chest, the sudden certainty that you must respond right now.
Survive the surge
Learn your three tells
Identify your first physical signals — clenched jaw, hot face, held breath, a spike of righteous certainty. The tell is your cue that judgment is temporarily offline and the clock should start.
Buy ninety seconds
Don't act inside the spike. Exhale slowly, take a sip of water, say “let me think about that for a moment.” The chemistry fades fast — unless you keep feeding it with the story.
Never hit send from inside a hijack
Draft the reply if you must — then park it. Messages and decisions composed during the surge are written by the alarm, and the alarm is a terrible writer.
- Would I send this tomorrow morning?
- What, exactly, is the emergency?
You can't stop the alarm from ringing. You can stop handing it the wheel.
