Peters' model splits the brain into three functional parts. The Chimp is the orbitofrontal system: fast, emotional, impulsive, catastrophic, working on feelings, intuition and trigger points. It is a defence and warning machine you were given at birth and cannot control. The Human is the dorsolateral prefrontal cortex: slower, works with facts, logic and acceptance, and looks for solutions. The Computer is the central memory bank, blank at birth, programmed by both the Chimp and Human with beliefs and behaviours — and it can override both. The practical skill is recognising which system you are in, thanking the Chimp for its warning, then deliberately switching systems to find a solution. Peters insists you manage, never control, and that both systems working together outperform either alone.

How to run it
- 1
Learn which system you have been given
Establish where your Chimp sits on the reactivity spectrum. Some people have highly strung, impulsive Chimps; others have quiescent, calm ones. Neither is better — a calm Chimp misses danger cues, a reactive Chimp warns you fast. Peters frames this as understanding the machine you were issued rather than judging it.
Pro tip Ask people close to you where they see you reacting emotionally versus rationally — you are too close to judge your own machine.

Recognise the Chimp speaking
Emotional reactions, catastrophic thinking, impulsivity, wanting guarantees, needing to be loved by everyone, and refusing facts are all signals you are in Chimp mode. Peters notes the Chimp gets in first because the Human system is slower and 'comes late to the party'.
Watch out Do not treat the Chimp as your fault or your identity. Peters is explicit: 'your mind and you are different' — it is a machine, not a character flaw.
- 3
Thank the Chimp for the message
The Chimp's job is to disturb you until you pay attention. Acknowledge it rather than argue with it or engage with the emotion itself. Peters: 'if you get anxious go thank you thank the chimp you've got me anxious let me work the plan out'.
Watch out If you never answer it satisfactorily, it will keep disturbing you and escalate.
- 4
Switch systems with 'what's the plan?'
Immediately convert the emotional alert into a Human-mode task by asking 'okay, I've now got an emotional message — what's the plan?' Peters says the act of asking for a plan flicks you from Chimp into Human, and calmness follows because the Chimp registers that you are on the case.
Pro tip Program this as an automatic response to every setback, so it fires before the emotion escalates.
Watch out Sometimes the plan is not a fix. For genuine loss, the plan is accepting the process — 'you've got three months of rough and tumble coming'.
- 5
Answer the Chimp with something that genuinely satisfies it
Use facts, perspective and values to give the Chimp a reassuring answer. If rational thinking is not strong enough on its own, use people — the Chimp works externally and listens to close friends, partners or a parental figure more than to the public.
Pro tip Identify in advance whose opinion your Chimp actually listens to; for some people it is a partner, for others a mentor or older figure.
Watch out The Chimp wants guarantees, and life offers almost none. Reassure it instead with 'I will always be active in finding solutions, and I know people who can help'.
- 6
Program the Computer with autopilots
Install truthful, evidence-based beliefs and behaviours that fire automatically. Peters aims for about five 'grade A hits' — autopilots that genuinely resonate, such as 'will this matter in a week's time?' or 'if this helps ten people, I'm happy'.
Pro tip Test resonance out loud. An autopilot that works for someone else but does not land for you will fail under pressure.
Watch out A belief you do not actually believe is useless. Peters: 'whereas if you don't really believe it then it won't work'.
- 7
Use each system where it belongs
Let the Chimp drive ambition, excitement and motivation during preparation — 'I'm going to get the gold medal' — then switch to Human afterwards for perspective, commitment and values. Peters: use the Chimp in training, then 'when you've finished switch to human and be proud of the fact you gave it everything'.
Pro tip Leave every session, launch or performance in Human mode so you exit in a reasonable state of mind.
Watch out Do not try to kill the Chimp. Peters: 'the chimp gives the absolute flavour, colour, excitement, driving your life'.
In the wild
Ali described fixating on a single negative comment among a hundred positive ones. Peters reframed imposter syndrome as a positive: the Chimp brain is sending a message asking you to check. Its job is the warning, not the solution. The Human's job is to answer it — either by examining the work honestly (am I articulate, am I getting what my audience needs?) or by shifting to values (am I doing what I think is genuine? If I reach ten people who move, is that more important than a million who don't?). Once the Chimp gets an adequate answer, it stops disturbing you, and the syndrome becomes a productive prompt rather than a negative loop.
→ Imposter syndrome converts from a paralysing self-attack into a routine quality check that resolves once answered.
Ali's team noticed that after US conferences he would return with grandiose 10x and 20x business ideas driven by adrenaline and atmosphere. They created a rule: whenever he proposes a new idea, anyone can invoke a 72-hour button, pausing the decision for three days. If he is still excited after three days, they consider it. On many occasions he had forgotten the idea entirely. Peters' response was notable: he would not prescribe the three-day wait. He would first ask whether, had Ali acted impulsively and it went wrong, he would still be glad he jumped in. Only if the honest answer showed real cost — sleepless nights, irritability, degraded decision-making — would he introduce insight and let Ali arrive at his own rule.
→ A team-level guard rail against Chimp-driven impulsivity, self-generated rather than imposed.
A former student working with the cycling team asked Peters to see an athlete with mental health problems. Peters simply tried to explain to him how his mind works, and the athlete did exceptionally well. The head of cycling then introduced him to Chris Hoy, who knew precisely what he wanted from the relationship — it was not about emotions but about performance and focus. Peters describes a Chimp that was 'really well behaved'. He was later invited to the Athens Olympics, initially refused a full-time job because he had trained as a doctor to help people, and took a year to conclude that helping sportspeople with performance or life was still helping people.
→ The chimp model moved from psychiatric practice into elite sport, and from there into football, snooker, media, education and the police.
Common mistakes
Trying to control instead of manage
Peters calls telling someone to control their emotions 'almost abusive' — it asks them to do something neuroscientifically impossible, like jumping out a window and flying. There are no control circuits over the orbitofrontal system, only modulating ones. Control implies an option you can exercise at will; management is a skill you build over time and sometimes execute badly. Framing it as control makes people beat themselves up asking 'what is wrong with me?' when the honest answer is that they need to upskill.
Killing the Chimp or chasing pure rationality
People often conclude the goal is to suppress the Chimp and live permanently in Human mode. Peters rejects this. The Chimp supplies laughter (there are no laughter circuits in the Human system), motivation, excitement and fast intuitive warnings that research shows are frequently more accurate than laboured logic. He also corrects the common misreading that Human equals logic and Chimp equals emotion — both use both, the difference is which one leads.
Removing a Gremlin without replacing it
You cannot delete a pathway by resolving not to use it. Peters' eating example: deciding 'today I'll eat sensibly' without changing any underlying belief or behaviour just routes you down the same pathway again. Removal requires installing a new truthful autopilot in its place, and because beliefs 'don't dance alone' — each is propped up by five, six or seven supporting beliefs — you have to find and knock over the whole gang.
