Reasoning pattern library

Recognise the move.
Then test the claim.

Weak reasoning rarely announces itself. It arrives as a familiar shortcut: benefit becomes causation, repetition becomes confirmation, neutrality becomes asymmetry, and a true detail expands into a total explanation.

This library names those moves without diagnosing the people who use them.

46patterns across six analytical domains

How to use the library

01Recognise

Find the pattern that resembles the reasoning—not merely the conclusion.

02Test

Use the diagnostic question on both the claim and your own response.

03Reframe

Replace the shortcut with a conclusion that matches the evidence.

46 patterns

01Evidence & sourcesCircular sourcing“Many outlets are confirming it.”
How it works

Several articles appear independent but all trace back to the same original assertion, clip or anonymous account.

Why it persuades

Repetition creates the impression of corroboration even when no new evidence has been added.

Diagnostic question

Trace every report backwards. How many genuinely independent evidence lines remain?

More careful formulation

Several outlets repeat one originating claim; independent confirmation has not yet been established.

02Evidence & sourcesSource laundering“A respected publication reported the allegation.”
How it works

A weak claim gains credibility by being quoted by progressively more reputable or distant intermediaries.

Why it persuades

Readers remember the prestigious outlet but forget that it merely cited an unverified source.

Diagnostic question

What did the most authoritative source independently verify rather than repeat?

More careful formulation

The allegation has travelled through reputable outlets, but its original evidence remains unchanged.

03Evidence & sourcesContext collapse“The clip speaks for itself.”
How it works

A genuine quotation, image or video is detached from the surrounding event, date, question or sequence.

Why it persuades

Authentic material feels self-validating and reduces the impulse to inspect its original setting.

Diagnostic question

Find the full source. What happened immediately before and after the selected fragment?

More careful formulation

The material is authentic, but its meaning depends on context that must be restored.

04Evidence & sourcesScreenshot certainty“Here is the document—they cannot deny it.”
How it works

A screenshot substitutes for a traceable document, stable URL, metadata or verifiable chain of custody.

Why it persuades

The visual appearance of a record creates a feeling of direct access to hidden evidence.

Diagnostic question

Can the underlying document, sender, date and unedited version be independently authenticated?

More careful formulation

The screenshot is a lead. Until its origin is verified, it has limited evidential weight.

05Evidence & sourcesSingle-witness completion“An insider confirmed the entire operation.”
How it works

One person’s account is used to fill every missing part of a complex explanation.

Why it persuades

An insider narrative offers detail, intention and drama that fragmented public evidence cannot provide.

Diagnostic question

Which parts are independently corroborated, and which depend entirely on the witness’s interpretation?

More careful formulation

The witness provides a potentially important account, but each major element requires separate corroboration.

06Evidence & sourcesAuthority substitution“A professor, general or doctor said it.”
How it works

Status or expertise substitutes for evidence, including when the authority speaks outside their field.

Why it persuades

Credentials reduce uncertainty and the effort required to inspect the underlying case.

Diagnostic question

What is the person’s relevant expertise, and what evidence accompanies the claim?

More careful formulation

The expert’s view is relevant testimony, not a replacement for the evidence on which it rests.

07Evidence & sourcesAsymmetric source scepticism“Official sources are biased; this anonymous channel tells the truth.”
How it works

Institutional sources face maximal scrutiny while congenial alternative sources receive minimal scrutiny.

Why it persuades

Distrust feels independent, especially when the alternative source validates an existing identity or suspicion.

Diagnostic question

Would you accept the alternative source’s evidence standard if it supported the opposite conclusion?

More careful formulation

Both institutional and alternative sources should be tested for access, incentives, record and verifiability.

08Evidence & sourcesImpossible proof demand“Unless every detail is public, the official account is worthless.”
How it works

One explanation is required to eliminate all uncertainty while the preferred alternative is accepted on possibility alone.

Why it persuades

Residual uncertainty is mistaken for equal support between competing explanations.

Diagnostic question

Are both explanations being asked to carry the same burden of proof?

More careful formulation

Unanswered questions reduce confidence, but do not automatically validate a less-supported alternative.

09Causality & explanationProfit therefore cause“They benefited, so they must have created it.”
How it works

A real benefit or financial interest is treated as evidence of decision, causation and execution.

Why it persuades

Following the money is often useful, making the unsupported final leap feel investigative.

Diagnostic question

Where is the evidence connecting benefit to prior intent, decision and implementation?

More careful formulation

The benefit establishes an incentive worth investigating; it does not by itself establish causation.

10Causality & explanationAfter this, therefore because of this“The change happened immediately after the event.”
How it works

Temporal sequence is treated as sufficient proof that the earlier event caused the later outcome.

Why it persuades

Time order is visible and intuitive, while alternative causal processes are harder to see.

Diagnostic question

What mechanism links the events, and does the relationship persist across comparable cases?

More careful formulation

The timing supports a possible relationship that still requires a mechanism and comparison.

11Causality & explanationPossibility inflation“It could be done, therefore it probably was.”
How it works

Technical or theoretical possibility is silently upgraded to probability or fact.

Why it persuades

Demonstrating feasibility feels like uncovering a hidden capability.

Diagnostic question

What evidence shows that the capability was selected, used and effective in this case?

More careful formulation

The scenario is possible. Its probability depends on evidence of use, not capability alone.

12Causality & explanationSingle-cause compression“This one decision explains everything that followed.”
How it works

A complex outcome is reduced to one actor, event or motive while interacting causes disappear.

Why it persuades

A single cause makes a confusing world coherent, memorable and morally legible.

Diagnostic question

Which necessary conditions, independent actors and feedback loops have been removed?

More careful formulation

The factor may be important without being sufficient; map the interacting causes and constraints.

13Causality & explanationMotive as proof“They wanted this outcome, so the allegation fits.”
How it works

A plausible desire is treated as evidence that a person chose and executed a particular action.

Why it persuades

Motive supplies a psychologically satisfying bridge across missing evidence.

Diagnostic question

What distinguishes this suspect from every other actor who shared the same incentive?

More careful formulation

Motive narrows inquiry; it does not establish action without opportunity, decision and evidence.

14Causality & explanationEffect proves intent“The policy produced control, so control was always the plan.”
How it works

A consequence is read backwards as proof of the original objective.

Why it persuades

Outcomes are observable, while intentions are hidden, so the former is used to manufacture the latter.

Diagnostic question

Was the effect predicted, chosen, accepted as a trade-off, or merely produced?

More careful formulation

The consequence is real; intent requires separate evidence from planning, communication or repeated choice.

15Causality & explanationAgency erasure“They had no choice; the other side forced them.”
How it works

Pressure and context are described as total causes, removing the decision-maker’s remaining alternatives and responsibility.

Why it persuades

It creates a clean causal chain and often protects the actor with whom the speaker identifies.

Diagnostic question

What alternatives existed, and how did comparable actors respond under similar pressure?

More careful formulation

External pressure shaped the decision without necessarily eliminating agency or responsibility.

16Causality & explanationComplexity means coordination“This could not happen without someone controlling it.”
How it works

A complex or patterned result is assumed to require a central planner rather than interacting incentives and local choices.

Why it persuades

Intentional design is easier to imagine than emergent systems, institutional routines or cascading errors.

Diagnostic question

Can the same pattern emerge from shared incentives, imitation, rules or decentralised adaptation?

More careful formulation

Coordination is one hypothesis; emergent and structural explanations must be tested alongside it.

17Narrative & framingFact-kernel expansion“That part is true, so the larger story is basically confirmed.”
How it works

A documented error, interest or abuse is expanded until it appears to prove an entire hidden plan.

Why it persuades

The true core lends its emotional and evidential force to claims that were never independently demonstrated.

Diagnostic question

Where does the evidence stop and the narrative begin?

More careful formulation

Acknowledge the fact kernel precisely, then test every additional causal and intentional claim separately.

18Narrative & framingSelective timeline“The conflict began when the other side acted.”
How it works

The story starts at the moment that makes one actor reactive and the other solely responsible.

Why it persuades

Choosing the starting point quietly allocates cause, innocence and moral legitimacy.

Diagnostic question

How does the interpretation change if the timeline begins earlier—or later?

More careful formulation

State the chosen time horizon and explain why earlier events are relevant or excluded.

19Narrative & framingFalse binary“Either you accept this explanation or you trust everything authorities say.”
How it works

Multiple positions are collapsed into two mutually exclusive camps.

Why it persuades

Binary choices reduce cognitive effort and turn uncertainty into loyalty.

Diagnostic question

What credible third positions combine criticism with different causal conclusions?

More careful formulation

Rejecting one explanation does not require endorsing its strongest opponent.

20Narrative & framingConclusion hidden in the description“The regime’s latest propaganda law proves…”
How it works

Evaluative or causal conclusions are embedded in the nouns and labels used to describe the evidence.

Why it persuades

The framing is accepted before the argument begins, making the conclusion feel observed rather than inferred.

Diagnostic question

Can the event be restated in neutral, observable language without losing factual content?

More careful formulation

Separate the observable act from the judgement about its purpose or legitimacy.

21Narrative & framingAnecdote becomes system“This case shows how the whole system works.”
How it works

A vivid individual case is generalised into a population-wide or institutional pattern.

Why it persuades

Concrete stories are memorable and emotionally stronger than base rates or representative data.

Diagnostic question

How common is the case, and how was the comparison population selected?

More careful formulation

The case establishes possibility and may justify investigation; prevalence requires broader evidence.

22Narrative & framingScale collapse“Fraud exists, therefore the entire result is fraudulent.”
How it works

Evidence that something occurred is treated as evidence that it occurred at decisive scale.

Why it persuades

The existence question is easier to prove than the magnitude question, and the distinction disappears in debate.

Diagnostic question

What is the measured frequency, distribution and effect on the outcome?

More careful formulation

The problem is real; its scale and consequence must be established separately.

23Narrative & framingCategory inflation“This disagreement is censorship, violence, treason or genocide.”
How it works

A serious category is expanded to include materially different conduct.

Why it persuades

The stronger label imports urgency, moral clarity and historical associations.

Diagnostic question

What are the category’s defining criteria, and does the case satisfy each one?

More careful formulation

Use the narrowest accurate term; severity should come from evidence, not vocabulary.

24Narrative & framingPattern completion“Once you see the pattern, every new event fits.”
How it works

Ambiguous events are interpreted through an existing template until the template appears universally confirmed.

Why it persuades

Recognising patterns produces insight and control, especially during uncertainty.

Diagnostic question

Which observations would not fit the pattern, and are they being noticed or explained away?

More careful formulation

Treat the pattern as a hypothesis with specified predictions and failure conditions.

25Identity & cognitionIdentity-protective reasoning“Criticising this claim feels like attacking who we are.”
How it works

Evidence is evaluated partly by whether accepting it would threaten group belonging, dignity or moral identity.

Why it persuades

Beliefs help maintain relationships and self-respect; revising them can carry real social cost.

Diagnostic question

Can you state what evidence would matter without referring to the identity of the people presenting it?

More careful formulation

Protect the person’s dignity while keeping the factual claim open to revision.

26Identity & cognitionConfirmation filtering“Every serious source I follow agrees.”
How it works

Supporting material is sought, remembered and shared more readily than disconfirming material.

Why it persuades

Agreement feels like accumulated evidence when the information environment has already been filtered.

Diagnostic question

What is the strongest credible evidence against your view, and where did you look for it?

More careful formulation

Search deliberately for evidence that could reduce confidence, not merely refine the preferred account.

27Identity & cognitionContrarian certainty“Most people believe it, which is why it is probably false.”
How it works

Opposition to consensus becomes a proxy for independence and truth.

Why it persuades

The believer gains a valued identity as someone difficult to manipulate.

Diagnostic question

Is the conclusion supported by positive evidence, or mainly by distrust of the majority?

More careful formulation

Consensus can be wrong, but dissent earns credibility through evidence rather than rarity.

28Identity & cognitionBelief perseverance“That evidence was wrong, but the conclusion is still obviously right.”
How it works

A conclusion survives after the original reasons for accepting it have collapsed.

Why it persuades

The belief has become connected to other beliefs, memories and social commitments.

Diagnostic question

If the failed evidence had never existed, what independent case would remain?

More careful formulation

Recalculate confidence from the evidence that survives rather than preserving the prior conclusion.

29Identity & cognitionMoral credentialing“I stand for peace and compassion, so my policy must be the humane one.”
How it works

A virtuous value or self-description is used to bypass analysis of outcomes, trade-offs and other people’s agency.

Why it persuades

Moral identity supplies certainty and status while shielding practical claims from scrutiny.

Diagnostic question

What concrete action follows, who bears its risks, and how will success be verified?

More careful formulation

Shared values do not settle which strategy best serves them; compare mechanisms and consequences.

30Identity & cognitionSpiritual or moral bypassing“Anger and resistance only show that you have not risen above the conflict.”
How it works

Language of peace, unity or higher awareness avoids power, accountability, grief and concrete harm.

Why it persuades

Abstract ideals promise purity and distance from painful political responsibility.

Diagnostic question

Does the principle increase accountability for every actor—or mainly restrain the vulnerable one?

More careful formulation

Ethical ideals should sharpen attention to responsibility and consequences, not erase them.

31Identity & cognitionMoving goalposts“That evidence is not enough; now prove this additional condition.”
How it works

The acceptance threshold changes each time the previous demand is met.

Why it persuades

The belief remains protected without the person having to declare it immune to evidence.

Diagnostic question

Write down the evidence standard before examining the next piece of evidence.

More careful formulation

Agree in advance what would increase, reduce or settle confidence—and apply it consistently.

32Influence & attributionResemblance becomes attribution“This sounds exactly like state propaganda, so we know who is behind it.”
How it works

Similarity in theme or wording is treated as proof of origin, coordination or control.

Why it persuades

Recognising familiar narratives feels like recognising the actor who created them.

Diagnostic question

What behavioural, technical or documentary evidence connects the content to the alleged source?

More careful formulation

The narrative resembles known messaging; attribution remains a separate evidential question.

33Influence & attributionContent–behaviour conflation“The claim is false, therefore its spread is a coordinated operation.”
How it works

The accuracy of content is confused with the behaviour used to distribute it.

Why it persuades

A false claim makes malicious coordination feel more plausible, even when distribution evidence is absent.

Diagnostic question

What indicators show concealment, coordination, impersonation or artificial amplification?

More careful formulation

Assess content, distribution behaviour and actor attribution as three distinct questions.

34Influence & attributionVirality becomes authenticity“Millions are sharing it, so ordinary people clearly know something.”
How it works

Reach and engagement are treated as evidence that a claim is true or organically popular.

Why it persuades

Large numbers create social proof while the mechanisms producing them remain invisible.

Diagnostic question

Is the reach independent, paid, coordinated, recommendation-driven or concentrated in a small network?

More careful formulation

Virality measures circulation, not truth—and may not measure genuine public support.

35Influence & attributionBot by disagreement“No real person would argue this; the account must be a bot or troll.”
How it works

An implausible or hostile opinion is converted into an identity and coordination claim.

Why it persuades

It removes the need to engage with the argument and protects one’s model of what normal people believe.

Diagnostic question

What technical or behavioural evidence exists beyond the content of the opinion?

More careful formulation

The account may be inauthentic, but unusual views are not sufficient evidence of automation.

36Influence & attributionOrganic–amplified confusion“Either the movement is genuine or it is manufactured.”
How it works

A real grievance and strategic amplification are treated as mutually exclusive explanations.

Why it persuades

A binary origin story is simpler than interaction between citizens, platforms, activists and state actors.

Diagnostic question

What existed organically, and what evidence shows later selection, funding or amplification?

More careful formulation

Authentic grievances can be strategically amplified without becoming invented or centrally controlled.

37Influence & attributionSynchrony proves coordination“They all posted the same message at once.”
How it works

Similar timing is treated as sufficient proof of a hidden command structure.

Why it persuades

Synchrony is visible and genuinely can indicate coordination, making overconfidence easy.

Diagnostic question

Could shared news, templates, platform trends or public calls to action produce the timing?

More careful formulation

Synchrony is an indicator to investigate, not a complete attribution case.

38Influence & attributionPersistence proves central intent“The narrative keeps returning, so someone must be directing it.”
How it works

A durable story is assumed to require continuous central management.

Why it persuades

Long-lived narratives appear too resilient to be sustained by incentives, identity and repetition alone.

Diagnostic question

What decentralised rewards or recurring events could reproduce the narrative without one controller?

More careful formulation

Persistence may reflect coordination, but also durable grievances, identities and media incentives.

39Debate & neutralityFalse balance“There are two sides, so both deserve equal weight.”
How it works

Equal opportunity to speak is confused with equal evidential support or equal responsibility.

Why it persuades

Symmetry feels fair and protects the speaker from appearing partisan.

Diagnostic question

Are the evidence, actions and responsibilities actually comparable?

More careful formulation

Represent relevant perspectives fairly while weighting claims according to evidence.

40Debate & neutralityPseudo-neutrality“I am neutral—I only question one side.”
How it works

A neutral identity is claimed while explanations, demands and scepticism consistently favour one party.

Why it persuades

The label of neutrality provides moral and rhetorical protection from scrutiny.

Diagnostic question

Which concrete, verifiable demands are placed on the side that is rarely criticised?

More careful formulation

Neutrality should be evaluated through the distribution of standards, agency, risk and responsibility.

41Debate & neutralityAsymmetric pacifism“The reachable side must disarm; the aggressor’s force is simply reality.”
How it works

Restraint is demanded primarily from the party open to persuasion, while the coercive actor’s choices are treated as fixed.

Why it persuades

It offers an actionable path and a peaceful identity, even if the resulting incentives are one-sided.

Diagnostic question

What simultaneous, verifiable action is required from the actor using or threatening force?

More careful formulation

Peace proposals must distribute obligations, verification and consequences across the relevant actors.

42Debate & neutralityMotte and bailey“I never claimed control—only that powerful people influence events.”
How it works

A strong, vulnerable claim retreats to a safe, obvious claim when challenged, then later returns unchanged.

Why it persuades

The speaker gains the impact of the strong claim and the defensibility of the weak one.

Diagnostic question

Which exact version is being defended, and does the evidence support that version?

More careful formulation

Keep the modest claim modest; stronger conclusions require additional evidence.

43Debate & neutralityWhataboutism“Why discuss this when the other side did something worse?”
How it works

A relevant comparison becomes a device for avoiding the original claim rather than evaluating it.

Why it persuades

Real hypocrisy and inconsistency make diversion feel like correction.

Diagnostic question

Does the comparison change the truth of the first claim, or only expose another issue?

More careful formulation

Evaluate the original claim, then examine the comparison under the same standard.

44Debate & neutralityBurden shifting“Prove that the hidden operation did not happen.”
How it works

The person making an extraordinary or hidden-intent claim requires others to disprove it.

Why it persuades

Some negative claims are impossible to prove, allowing suspicion to survive indefinitely.

Diagnostic question

What positive evidence supports the allegation, and who introduced it?

More careful formulation

The claimant carries the burden of showing the specific actor, mechanism and evidence.

45Debate & neutralityClaim flooding“Explain these twenty examples before dismissing the theory.”
How it works

Many weak or unrelated claims are presented faster than they can be checked.

Why it persuades

Volume creates an impression of cumulative evidence and makes any incomplete reply look evasive.

Diagnostic question

Which single claim is strongest, precise and independently testable?

More careful formulation

Examine one representative claim fully before treating the collection as cumulative proof.

46Debate & neutralityTone substitutes for substance“The calm speaker is rational; the angry speaker is unreliable.”
How it works

Presentation style is treated as evidence for the truth or morality of the underlying claim.

Why it persuades

Composure resembles competence, while justified emotion can feel threatening or biased.

Diagnostic question

Would the evidence change if the same words were delivered in a different tone?

More careful formulation

Assess conduct and evidence separately; neither calmness nor anger determines factual accuracy.

A necessary caution

A pattern is a prompt for examination—not a verdict.

Finding one of these patterns does not automatically make the conclusion false. A weak argument can point toward a true conclusion, and a polished argument can support a false one. Use the pattern to identify what still needs to be demonstrated.
