Sleight of Mouth — The Fifteen Ways to Take a Belief Apart
A belief is a claim with joints. This is the map of where they are.
Robert Dilts spent the 1980s taking Richard Bandler’s arguing apart, expecting to find improvisation. He found a finite set instead: fourteen moves, each coming at a stated belief from a different angle. That sounds like a modest result. It is not, because arguing on instinct means reaching for whichever objection happens to be nearest, and knowing the set means noticing the ones you never reach for.
The moves work because a belief is almost never a single claim. It is two claims joined at a hinge, and the hinge is usually the softest part of it.
“I enjoy Coca-Cola because it tastes good” puts one thing behind another as its cause. “Too many responsibilities means I cannot train” asserts that two quite different things are the same thing. Dilts calls these cause-effect and complex equivalence. Either way you end up with three places to push rather than one: the first term, the second term, and the join between them.
What follows is that set drawn as a map. The belief sits in the middle and the moves are arranged around it — not for tidiness, but according to what each one actually does.
How to read the map
Both directions carry meaning. Intent sits before the belief because it asks what the belief was protecting in the first place, and Consequence sits after it because it asks what follows once you act on it.
Height works the same way. The further up a move sits, the further back it stands from the claim, which is why Meta Frame runs across the very top — it frames the whole argument rather than either term of it.
On the real map every one of those positions is filled by a named move, and its colour marks which of the four families it belongs to. Select any of them and the panel underneath shows that move applied to the belief in front of you.
A belief nobody defends
Start somewhere with nothing at stake. Nobody’s sense of themselves is bound up in a soft drink, so the moves land cleanly and you can watch the mechanism rather than the argument. Select any node to see that move applied.

All fifteen moves in text — An everyday habit
- Meta FrameChallenge the basis for the belief.
I need the familiarity of proven consumables in order to create a satisfyingly satiated result.
- Chunk UpGeneralize in order to change the relationship defined by the belief.
My diet impacts my future health.
- Hierarchy of CriteriaRe-assess the belief based on a more important criterion.
Be healthy in the future › enjoy food now › feel refreshed. Ranked in that order, the drink loses.
- Frame SizeRe-evaluate the implication of the belief in the context of a longer (or shorter) time frame.
I enjoy sweet sparkling cold drinks because they make me feel satisfied and refreshed — but I am judging that over the next ten minutes, not the next ten years.
- Model of the WorldLook at the belief from a different perspective (model of the world).
Highly processed foods are designed to profit corporations.
- Reality StrategyRe-assess the belief based on the fact that beliefs are based on specific perceptions.
I am better off finding another way to refresh myself.
- Apply to SelfUse key aspects of the belief to challenge the belief.
Can I find something else that also tastes good, refreshes me, and is actually healthy?
- IntentWhat could be the positive intention?
To satisfy my taste while feeling refreshed.
- ConsequenceFocus a consequence that leads to challenging the belief.
I feel refreshed but also know I'm consuming unhealthy foods.
- Another OutcomePropose a different outcome that challenges the relevancy of the belief.
It satisfies my subconscious desire for childhood memories and feelings.
- Redefine CauseUse words that are similar but may infer something different.
I have had the habit of drinking Coca-Cola for years in the past.
- Redefine EffectUse words that are similar but may infer something different.
It seems to refresh me, but really only serves to disturb my metabolism, which ultimately causes less hydration.
- Counter ExampleFind an exception that challenges the generalization defined by the belief.
I have had many habits in the past that didn't serve my best interests — such as biting my nails, and eating entire chocolate bars in one sitting.
- AnalogyUse an analogy or metaphor that challenges the generalization defined by the belief.
Drinking Coca-Cola is a bit like drip-feeding myself hemlock.
- Chunk DownLook at a specific element that challenges the belief.
Coca-Cola cleans rusty nails and dissolves meat, so it is probably not good for my insides at all.
Reframes transcribed from the original working map.
A list of fourteen patterns would not show you what the map does. Look at Intent and Consequence, sitting at opposite ends of the same line.
They do opposite work. Intent grants the belief its reasonable motive, because nobody drinks Coca-Cola for no reason at all. Consequence takes the same belief and follows it forward until it embarrasses itself. Neither is much of a rebuttal alone, and together they close a pincer.
The vertical pair behaves the same way. Chunk Up and Chunk Down sit above and below the claim and both dissolve it — one by making it too small to matter, the other by making it too specific to survive.
Using it on a belief of your own
Write the belief as two terms and a hinge. If you cannot get it into “A because B” or “A means B”, you do not have a belief yet — you have a mood. This is most of the work, and it is the step almost everyone skips.
Then walk the map rather than free-associating. No single move is decisive and most are not meant to be. The value is that fifteen fixed positions make the gaps obvious, where a mind reaching for a counter-argument returns to the same three every time.
Turn it on yourself before anyone else. These are persuasion moves, which is exactly why the honest use is inward. A belief of your own that survives all fifteen has earned its place, and one that does not was being held for a reason you had never looked at.
That last conclusion is not original to this piece. It is where the Cognitive-Motivational Bias Matrix arrives structurally, reached here one conversation at a time instead.
The fifteen moves in full
Everything above is the same fifteen moves applied twice. Here they are on their own, with what each one does and the definition Dilts gives it, grouped by what they change about the belief.
Fourteen of these are Dilts’ patterns. Redefine takes two slots here, one for each term of the belief. The four groupings are ours.
Change the frame
Move up or down a level of abstraction, or widen the window the belief is judged in.
- Meta Frame
Step outside the argument entirely and ask what kind of belief this is, and where it came from. Not "is it true" but "what is this a belief about".
Dilts: “Challenge the basis for the belief.”
- Chunk Up
Go up a level of abstraction until the specific claim dissolves into the larger one it belongs to.
Dilts: “Generalize in order to change the relationship defined by the belief.”
- Hierarchy of Criteria
Name something the person values more than the thing the belief protects, and rank them out loud.
Dilts: “Re-assess the belief based on a more important criterion.”
- Frame Size
Change the window. A year, a lifetime, a generation — most beliefs are sized to one span and fail in another.
Dilts: “Re-evaluate the implication of the belief in the context of a longer (or shorter) time frame.”
- Chunk Down
Go down into the detail until the generalisation stops covering what is actually there.
Dilts: “Look at a specific element that challenges the belief.”
Change whose view it is
Ask who holds the belief, how they know, and whether it survives being turned on itself.
- Model of the World
Ask how this looks to someone whose interests differ — and whose map is not yours.
Dilts: “Look at the belief from a different perspective (model of the world).”
- Reality Strategy
Ask how the person came to know this. Beliefs are built from particular evidence, and the evidence can be examined.
Dilts: “Re-assess the belief based on the fact that beliefs are based on specific perceptions.”
- Apply to Self
Turn the claim on itself and see whether it survives its own standard.
Dilts: “Use key aspects of the belief to challenge the belief.”
Move along the timeline
Step backwards to what was wanted, or forwards to what follows.
- Intent
Step back to what the belief is trying to protect. Almost every belief is guarding something reasonable.
Dilts: “What could be the positive intention?”
- Consequence
Step forward to what actually follows if the belief is acted on.
Dilts: “Focus a consequence that leads to challenging the belief.”
- Another Outcome
Suggest the belief is aimed at the wrong target — that something else is really at stake.
Dilts: “Propose a different outcome that challenges the relevancy of the belief.”
Restate the terms
Swap a word, find the exception, or hold the shape of the claim up against something else.
- Redefine Cause
Swap the wording of the cause for something near-synonymous that carries a different charge.
Dilts: “Use words that are similar but may infer something different.”
- Redefine Effect
Do the same to the effect — restate what is claimed to follow, in words that change its colour.
Dilts: “Use words that are similar but may infer something different.”
- Counter Example
One clear case where the rule does not hold. Generalisations are brittle against a single exception.
Dilts: “Find an exception that challenges the generalization defined by the belief.”
- Analogy
Hold the shape of the claim up against something else with the same shape and a different verdict.
Dilts: “Use an analogy or metaphor that challenges the generalization defined by the belief.”
Appendix — a second map
The example above works because everybody already has instincts about a soft drink. This one is the opposite case: a specific, technical claim from a field most people have never formed any view on at all.
That makes it the more honest test of the method. Where you have no ready-made opinion, the fifteen positions are doing the whole job rather than dressing up something you already thought.

All fifteen moves in text — Longevity spend
- Meta FrameChallenge the basis for the belief.
This is a claim about political mechanism dressed as a claim about budgets. Whether the spending ratio is right and whether activism is the lever that moves it are two separate questions, and only one of them is being argued.
- Chunk UpGeneralize in order to change the relationship defined by the belief.
Every society decides how much of the present it will spend on a future it will not personally see. Health budgets are one instance of that decision, not a special case.
- Hierarchy of CriteriaRe-assess the belief based on a more important criterion.
There is a role for healthcare spend on urgent and acute needs in the present, but the ratio should not be 99.9 : 0.1. Long-term outranks short-term — until someone is dying today.
- Frame SizeRe-evaluate the implication of the belief in the context of a longer (or shorter) time frame.
Over a single parliament, the acute spend is unarguable. Over a century, the ratio looks like a civilisation that spent everything treating what it had already decided not to prevent.
- Model of the WorldLook at the belief from a different perspective (model of the world).
To a health minister with a four-year term and a waiting list, "long-term" is the category that never survives a budget round — not because it is wrong, but because nobody is measured on it.
- Reality StrategyRe-assess the belief based on the fact that beliefs are based on specific perceptions.
How would we know this was working? "Longevity investment" has no agreed measure, which means the belief cannot currently be checked — only asserted.
- Apply to SelfUse key aspects of the belief to challenge the belief.
If a small coordinated group really can redirect national spending, then the group currently holding the 99.9% is also small and coordinated — which is an argument about who organises, not about what is true.
- IntentWhat could be the positive intention?
This is different from betting on a research milestone or a regulatory / jurisdictional arbitrage breakthrough. It wants a durable shift, not a lucky one.
- ConsequenceFocus a consequence that leads to challenging the belief.
Longevity would accelerate if health budget funding is allocated more to 'long-term solutions'.
- Another OutcomePropose a different outcome that challenges the relevancy of the belief.
The real bottleneck may not be the size of the budget but what counts as an approvable endpoint. Ageing is not a registerable indication, so money aimed at it has nowhere licensed to land.
- Redefine CauseUse words that are similar but may infer something different.
We need to drive public support for longevity investment.
- Redefine EffectUse words that are similar but may infer something different.
A higher ratio (than is apparent) of public funds — all money — should support maximum longevity rather than just getting by short-term.
- Counter ExampleFind an exception that challenges the generalization defined by the belief.
Tobacco control moved almost entirely through litigation, taxation and disclosure rules. It was one of the largest longevity gains in modern history and it did not come from a redirected research budget.
- AnalogyUse an analogy or metaphor that challenges the generalization defined by the belief.
It is the argument for maintaining the roof rather than buying more buckets — right in general, and no comfort at all to the person standing under the leak tonight.
- Chunk DownLook at a specific element that challenges the belief.
People should vote for political reform that encourages large pharmaceutical firms to focus on longevity rather than disease management.
Several of these reframes cut against the side making the argument, and that is what a full sweep of the map produces. Working it honestly means writing the moves that damage your own position alongside the ones that help it.
What is Dilts’, and what is ours
- Dilts’: the fourteen patterns, their definitions, and the two belief structures they operate on. The one-line definition under each move is his wording rather than ours.
- Ours: the map itself. Dilts publishes no diagram, no grouping of the fourteen, and no split of Redefine. The four families here, and giving Redefine a slot under each term of the belief, are drafting aids we added to make the set easier to learn.
- The reframes are illustrative, not claims about the world. They exist to demonstrate each move, and several of them contradict each other on purpose — which is what a full sweep of the map looks like.
Related research. Three companion pieces sit behind this one. The Cognitive-Motivational Bias Matrix maps the structure of systematic thinking error, the Personal Power Pie estimates how much of the population holds out against it, and the Die Pie asks the same question about how deliberately people treat their bodies.
All three describe the problem. This one is the practical end of the family — what you actually do, in a conversation, once you can see where the joints are.
