Adams' foundational model, drawn from his hypnosis training in his twenties. The common view is that humans are rational maybe 90% of the time with occasional emotional lapses. Hypnotists, advertisers and persuaders know the inverse: we're rational maybe 10% of the time, and only when no emotion and nothing consequential is involved. Everything else — marriage, career, politics, love — is decided irrationally and rationalized after. He calls us moist robots because cause and effect governs the chemistry inside the skull exactly as it governs a dropped ball outside it, which means we're programmable: by parents into religion, by countries into patriotism, by teams into positions we then experience as our own free choice.
Origin
In his twenties Adams went to school to become a trained hypnotist. What he learned about how people actually think, how they're persuaded, and the hard limits of rational thought was, in his word, world-changing — and inverted the standard assumption about human rationality. Decades of independent study of visual and verbal persuasion followed.
Core principles
- 01Humans are rational maybe 10% of the time — only when there's no emotion and nothing on the line.
- 02The rules of physics don't stop at the outside of your skull; brains run on cause and effect.
- 03Free will is an illusion tacked on after a decision is already made.
- 04Every big decision — who to marry, what job, what team — is made irrationally then justified.
- 05If people are programmable, then messages are inputs, not arguments.
How to run it
- 1
Invert your rationality assumption
Flip from 'people are 90% rational' to 'people are ~10% rational.' The 10% is confined to situations with no emotion and nothing on the line — arithmetic, route-planning.
Watch out The bigger and more identity-laden the decision, the less rationality is present.

Locate the programming
Ask what inputs shaped this person: parents' religion, country's patriotism, team membership. None of these are chosen — they're installed, then reinforced by the team once joined.
Pro tip The team filter is the biggest single bias. Find the team and you've found most of the answer.

Treat your message as an input, not an argument
Since the brain runs on cause and effect, persuasion is engineering inputs — fear, visuals, simplicity, repetition — rather than winning a debate.
Pro tip This is why every other framework in Adams' playbook works: they're all input design.
Watch out Facts, presented to an emotional decision, are simply weak inputs — not a fair fight you lost.

Let them keep the illusion
People will rationalize whatever they decided as their own reasoned choice. Don't fight the rationalization — it's the machine's normal output and it cements the decision.
In the wild
Adams argues you could swap the Democrats' and Republicans' policies entirely and roughly 80-90% of voters would still vote their party. The policies were never doing the work; team identity was.
→ Demonstrates that even on high-information, high-consequence decisions, stated reasons are post-hoc rationalization.
Interviewers describe a policy on the street but attribute it to the wrong figure — presenting Trump's position as Hillary's, or AOC's as Trump's. Respondents strongly endorse the policy when it comes from someone they like.
→ When told the true source, they reverse and say they'll 'have to rethink this' — exposing that the fact content never drove the position.
Common mistakes
Building your message around rationality
The default assumption — that people are mostly rational, so give them the facts — is precisely backwards. It produces persuasive messages that persuade nobody.
Assuming you're the exception
Adams says he feels himself being persuaded all the time despite having every tool to protect against it. Believing you're the rational one is itself the model in action.
Is it for you?
Best for
Anyone who must move people — marketers, negotiators, leaders, communicators.
Not ideal for
Genuinely stakes-free analytical decisions (balancing a checkbook, route-finding) where reason actually operates.
