mechanisms: Decision Rubric with Distinguishing Criteria

essence_one_line: Clarify a concept, option, signal, or identity by making its differences from nearby alternatives explicit.

compression_statement: When ambiguity persists because alternatives look too similar, sharpen contrast to clarify identity, choice, priority, or interpretation.

core_intuition: Ambiguity often persists because people see each item in isolation or notice the wrong differences. Contrastive differentiation works by placing confusable alternatives under shared dimensions, highlighting the few differences that actually matter, and linking those differences to a decision, diagnosis, category boundary, response, or interpretation.

canonical_formula: Contrastive Differentiation = comparison set + relevant contrast dimensions + distinguishing features + contrastive representation + decision or classification link. The archetype succeeds when the clarified difference changes recognition, choice, or interpretation; it fails when contrast becomes decorative, unfair, overstated, or disconnected from action.

structural_problem: Options, concepts, signals, roles, identities, explanations, or states are close enough that people confuse them, substitute one for another, or overlook their consequential differences. The problem is not simply lack of information; it is weakly organized difference. The relevant distinction is present but not salient, not represented on a shared dimension, or not linked to the action that depends on it.

condition: Nearby alternatives are being confused.

rationale: Use the archetype when people mistake one option, concept, state, role, signal, or explanation for another because the distinguishing difference is not explicit.

condition: The difference affects action, diagnosis, interpretation, or membership.

rationale: A contrast should matter. The archetype is strongest when the clarified distinction changes what people choose, classify, investigate, escalate, or learn.

condition: Items are described in incompatible frames.

rationale: When each alternative is explained with different language, metrics, or context, stakeholders cannot compare like with like.

condition: Definitions or labels are too abstract to guide real cases.

rationale: Contrastive examples, non-examples, and boundary cases can make the practical distinction visible.

condition: A signal is hidden inside background noise or similar states.

rationale: The archetype can differentiate critical from ordinary states when the response depends on recognizing the difference.

condition: Stakeholders over-focus on vivid but irrelevant differences.

rationale: The intervention can redirect attention from surface differences to the task-relevant contrast dimension.

condition: A downstream decision rule is being applied inconsistently.

rationale: Inconsistent decisions often reveal that the distinguishing criteria have not been made explicit enough.

symptom: People repeatedly ask whether two terms, options, or states are basically the same.

diagnostic_meaning: The comparison set lacks explicit contrast dimensions or boundary cases.

symptom: A decision meeting circles because alternatives are presented with different metrics or narratives.

diagnostic_meaning: The options need a shared representation before they can be responsibly evaluated.

symptom: Important warnings, exceptions, or abnormal states are missed because they resemble routine information.

diagnostic_meaning: The signal/state distinction is not sufficiently differentiated for the audience and context.

symptom: Training examples are memorized but learners fail on near misses.

diagnostic_meaning: The examples did not reveal the distinguishing feature that generalizes beyond the training case.

symptom: Two roles or teams duplicate work or leave gaps because boundaries are blurred.

diagnostic_meaning: The relevant differences in responsibility, authority, handoff, or scope need to be made explicit.

symptom: Stakeholders argue from labels rather than criteria.

diagnostic_meaning: The label is substituting for the actual distinction, so contrast must be grounded in features, evidence, and consequences.

root_tension: Simplifying a system often requires grouping similar things together, but good action often depends on noticing the exact differences inside a cluster of similar things. Contrastive differentiation balances cognitive compression with discriminating detail: it preserves enough similarity to compare fairly while amplifying the differences that matter.

case: The goal is simply to make one element dominate attention.

why_not: Use focal_emphasis_design. Contrastive differentiation clarifies differences among alternatives; focal emphasis makes a priority element stand out.

case: The main value comes from placing elements together to reveal any relation, including similarity, contradiction, analogy, or emergent meaning.

why_not: Use strategic_juxtaposition. Contrastive differentiation is narrower: it specifically sharpens relevant differences.

case: The categories and criteria are already clear and the task is to assign cases to classes.

why_not: Use a classification or decision-rule archetype. Contrastive differentiation may support the classification system, but it is not the entire assignment procedure.

case: The task is to estimate causal interaction effects between combined factors.

why_not: Use interaction_effect_mapping. Contrastive differentiation compares visible or represented differences; it does not by itself measure non-additive causal effects.

case: The contrast is aesthetic or rhetorical without a decision, diagnosis, learning, or interpretation link.

why_not: A visually striking contrast is not a solution archetype unless it changes understanding or action.

case: The compared items are not meaningfully comparable and no analogy frame is supplied.

why_not: Contrast without a fair frame can create false equivalence, misleading opposition, or manipulative persuasion.

structural_intervention: Identify the confusable alternatives, choose task-relevant contrast dimensions, name the distinguishing features, represent those differences in a shared frame, preserve necessary context, and connect the clarified contrast to the decision, classification, diagnosis, response, or learning objective that depends on it.

action: Name the confusion or ambiguity.

logic: Specify what people currently mistake, blur, substitute, or overlook. Without a named confusion, the contrast may target the wrong difference.

action: Define the comparison set.

logic: Include the focal item and the nearby alternatives, non-examples, baselines, or edge cases that cause confusion in practice.

action: Select contrast dimensions.

logic: Choose dimensions that matter for the target task rather than listing every observable difference.

action: Identify distinguishing features.

logic: State the features, criteria, evidence, consequences, thresholds, or boundary conditions that separate the items.

action: Build a contrastive representation.

logic: Encode the distinction through a table, paired examples, labels, visuals, annotations, rubric, diagnostic prompt, or other representation that makes differences inspectable.

action: Preserve context and comparability.

logic: Keep source, scale, uncertainty, baseline, and applicability notes visible enough that the contrast does not become misleading.

action: Link the contrast to use.

logic: Make clear what the audience should now decide, classify, diagnose, escalate, avoid, revise, or remember.

action: Test the distinction against boundary cases.

logic: Use near misses, exceptions, and ambiguous cases to see whether the contrast actually reduces confusion.

action: Revise when confusion persists.

logic: Update dimensions, examples, thresholds, labels, or representations when users continue to misclassify or choose poorly.

rule: Contrast only differences that affect the target task.

reason: Too many differences create clutter and can obscure the decisive distinction.

rule: Use shared dimensions before comparing alternatives.

reason: A fair contrast requires enough commensurability for people to inspect the difference without translating every item mentally.

rule: Include near misses when definitions are insufficient.

reason: Boundary cases reveal practical distinctions better than isolated positive examples.

rule: Choose visual or symbolic encodings proportional to consequence.

reason: Critical distinctions deserve stronger signals than minor distinctions, but over-signalization creates fatigue or false urgency.

rule: Disclose context when contrast could persuade misleadingly.

reason: Contrast has rhetorical power; the intervention should not rely on cherry-picked baselines or hidden criteria.

rule: Route differentiated contrast to a downstream action.

reason: A clarified difference should change a decision, classification, diagnosis, response, or learning outcome.

target_invariants: The comparison set remains relevant to the actual confusion or decision.

target_invariants: Contrast dimensions are tied to the task rather than to arbitrary or merely vivid differences.

target_invariants: Distinguishing features are specific enough to apply to new cases.

target_invariants: Context, uncertainty, and scale are preserved when needed for fair interpretation.

target_invariants: The contrast does not imply false dichotomy when hybrid, ambiguous, or overlapping cases exist.

target_invariants: The clarified difference has a downstream use: decision, classification, diagnosis, escalation, learning, or revision.

expected_outcomes: Reduced ambiguity among similar concepts, options, signals, roles, or states.

expected_outcomes: Faster recognition of decisive differences and fewer mistaken substitutions.

expected_outcomes: More consistent classification, diagnosis, selection, escalation, or interpretation.

expected_outcomes: Clearer communication of what matters and why it matters.

expected_outcomes: Better training transfer from examples to boundary cases and new situations.

expected_outcomes: Reduced attention spent on irrelevant differences and increased attention to task-relevant distinctions.

prose_essence:
Contrastive Differentiation is the intervention pattern for making consequential differences visible. It is useful when several things sit close together in a mental, operational, or representational space: similar concepts, plausible diagnoses, product options, status signals, roles, or cases. The archetype does not merely decorate one item with stronger contrast. It asks: what is being confused, which differences matter, how can those differences be represented fairly, and what action should the clarified distinction support?

The core move is to convert vague similarity into structured difference. A good contrast names the comparison set, chooses dimensions that matter for the task, identifies distinguishing features, preserves enough context to avoid distortion, and links the clarified difference to classification, diagnosis, choice, escalation, or learning.

prose_when_to_use:
Use this archetype when ambiguity persists because alternatives look, sound, or behave too similarly for the audience’s task. It fits concept learning when learners confuse neighboring ideas; operations when similar states require different responses; diagnosis when several explanations fit the evidence; procurement when vendors blur together; and organizational design when roles overlap without clear boundaries.

It is especially appropriate when definitions alone do not work. If people understand a label in theory but still misclassify boundary cases, a contrastive representation can expose the decisive feature. It is also appropriate when conversation has become stuck because each alternative is described in its own frame rather than compared across shared dimensions.

prose_structural_problem:
The structural problem is weakly organized difference. People are not necessarily ignorant; they may have too many descriptions, labels, examples, or signals without a clear account of what separates one from another. A concept is understood until it meets a near miss. A warning state appears routine until consequences reveal it was critical. A role sounds distinct until responsibilities overlap. An option looks attractive until compared against the constraint that matters.

This problem is intensified by isolated presentation. When items are described separately, the audience must mentally reconstruct the comparison. That reconstruction is expensive and often inaccurate. Contrastive Differentiation externalizes the comparison so the relevant difference becomes easier to inspect and apply.

prose_intervention_logic:
The intervention begins by naming the confusion: which things are being mistaken for one another, and why does the difference matter? It then defines the comparison set: the focal item, its nearest alternatives, relevant baselines, non-examples, edge cases, or previous states. Next, it chooses contrast dimensions that matter for the audience’s task. These dimensions might be risk, function, scope, evidence, time, cost, authority, severity, or membership criteria.

After the dimensions are chosen, the archetype identifies distinguishing features and encodes them in a contrastive representation. The representation may be a table, rubric, paired example, callout layer, diagnostic guide, or visual encoding. The last step is not optional: the clarified difference must be linked to use. The audience should know what the contrast changes: classify this case differently, choose this option under these conditions, escalate this signal, revise this policy, or remember this boundary.

A mature implementation then tests the distinction against boundary cases and misclassification data. When people still confuse alternatives, the contrast dimensions, examples, labels, or representation need revision.

prose_key_components:
### Comparison Set

Defines the nearby alternatives, concepts, signals, cases, roles, or states that must be distinguished from one another. Contrastive differentiation cannot operate on a single isolated item. The comparison set should include the focal item, likely confusions, near misses, baselines, or alternatives that people actually substitute for one another.

### Contrast Dimension

Names the axis on which the relevant difference is being made explicit. A contrast dimension can be function, risk, cost, membership condition, causal role, severity, time, evidence quality, scope, audience, or any other dimension that supports the intended decision or interpretation.

### Distinguishing Feature

Identifies the property, behavior, marker, criterion, or consequence that separates one item from its nearest alternatives. This component prevents contrast from becoming vague opposition. The difference must be stated precisely enough that people can recognize it in new cases.

### Contrastive Representation

Encodes the difference in a visible, audible, textual, procedural, tabular, spatial, or narrative form. The representation should make the relevant difference easier to notice without distorting scale, context, or uncertainty. Tables, paired examples, labels, diagrams, and annotation schemes can all instantiate this component.

### Classification or Choice Link

Connects the clarified difference to a decision, classification, interpretation, action, or learning objective. Without a downstream link, contrast can become explanatory ornament. This component states what changes after the difference has been clarified.

### Boundary Case Set

Includes edge cases, near misses, false friends, or confusing examples that reveal where the distinction holds or fails. Boundary cases are especially valuable when the ordinary definition sounds clear but breaks down in practice. They discipline the distinction by testing it against cases that invite misclassification.

### Relevance Filter

Separates differences that matter for the task from differences that are merely noticeable. The archetype should amplify task-relevant differences, not every difference. The relevance filter guards against clutter, stereotyping, spurious distinctions, and misleading rhetorical contrast.

### Context Preservation

Keeps enough background, uncertainty, scale, and source information attached to the contrasted items for fair interpretation. Contrast can mislead when items are stripped from context. This component helps preserve comparability while still making the difference salient.

### Audience Task Model

Specifies what the relevant audience is trying to decide, notice, learn, diagnose, or avoid confusing. A useful contrast for an expert may be useless or overwhelming for a novice, and a useful contrast for diagnosis may be irrelevant for purchasing, policy, or design. The task model tunes the difference.

### Revision Feedback Loop

Checks whether the differentiated contrast actually reduces confusion and updates the dimensions, examples, or representation when it fails. Because ambiguity often reappears in new forms, contrastive differentiation benefits from observing misclassification, mistaken choices, unresolved questions, or unintended interpretations.

### Optional Supporting Components

**Baseline Reference** — Provides a stable point of comparison such as a prior state, control case, benchmark, default option, or ordinary example. A baseline can make magnitude and direction visible, but it must be chosen fairly. A manipulative baseline can exaggerate or hide the relevant difference.

**Contrast Threshold** — Defines how large, reliable, or consequential a difference must be before it should be emphasized. Thresholds prevent over-differentiation, especially when minor variations are not meaningful for the audience or decision.

**Labeling Scheme** — Gives distinct names, tags, colors, symbols, or categories to differentiated items. Labels are powerful but dangerous: they can stabilize useful distinctions or freeze misleading ones. The label should serve the distinction, not replace it.

**Exception Note** — Marks situations where the contrast does not apply cleanly or where an item can belong to more than one side. This component is useful when contrast helps most cases but would become false if presented as an absolute dichotomy.

prose_common_mechanisms:
Mechanisms implement the archetype, but they are not the archetype itself. A contrast table, visual encoding, or diagnostic checklist only becomes Contrastive Differentiation when it is organized around a real confusion, task-relevant dimensions, distinguishing features, context preservation, and a link to use.

### Contrast Table

This artifact implements the archetype by helping users distinguish confusable alternatives. Places alternatives across shared dimensions so distinguishing features can be inspected side by side.

### Differential Diagnosis

This diagnostic method implements the archetype by helping users distinguish confusable alternatives. Compares plausible conditions, causes, or explanations by the features that distinguish them.

### Before/After Analysis

This temporal comparison method implements the archetype by helping users distinguish confusable alternatives. Clarifies a difference across time or intervention state by comparing the prior and changed condition.

### Product or Option Comparison Matrix

This decision support artifact implements the archetype by helping users distinguish confusable alternatives. Differentiates available options by features, constraints, costs, risks, and fit conditions.

### Concept Disambiguation Examples

This learning method implements the archetype by helping users distinguish confusable alternatives. Uses paired examples, non-examples, and near misses to clarify the boundary between concepts.

### Visual Contrast Encoding

This representation method implements the archetype by helping users distinguish confusable alternatives. Uses visual differences such as size, spacing, weight, shape, orientation, or color coding to make distinctions perceptible.

### Signal Highlighting

This attention method implements the archetype by helping users distinguish confusable alternatives. Marks the relevant signal or state difference so it is less likely to be lost in noise.

### A/B Comparison

This comparative evaluation method implements the archetype by helping users distinguish confusable alternatives. Compares two alternatives under a shared question so the practical difference between them becomes actionable.

### Near-Miss Case Pairing

This case learning method implements the archetype by helping users distinguish confusable alternatives. Pairs a correct case with a nearly similar incorrect case to make the decisive distinction clear.

### Decision Rubric with Distinguishing Criteria

This evaluation procedure implements the archetype by helping users distinguish confusable alternatives. Turns contrast dimensions into criteria that guide classification, selection, diagnosis, or action.

### Annotation and Callout Layer

This interface or documentation method implements the archetype by helping users distinguish confusable alternatives. Adds explanatory markers that point out why two apparently similar items are actually different.

### Confusion Audit

This review method implements the archetype by helping users distinguish confusable alternatives. Collects recurring misclassifications, mistaken substitutions, or ambiguous interpretations to identify where contrast must be sharpened.

Choose the mechanism based on the confusion. Tables fit multi-option comparisons; diagnostic procedures fit competing explanations; paired examples fit concept learning; signal highlighting fits state recognition; and rubrics fit repeated classification by multiple people.

prose_failure_modes:
### Irrelevant contrast amplification

**Cause:** The representation emphasizes differences that are visible but not task-relevant.

**Mitigation:** Use a relevance filter and test whether each contrast dimension changes the intended decision or interpretation.

### False dichotomy

**Cause:** The intervention presents alternatives as mutually exclusive when they overlap, blend, or vary by degree.

**Mitigation:** Add exception notes, gradient scales, hybrid categories, or boundary-case annotations.

### Cherry-picked comparison

**Cause:** The comparison set is selected to make one item look better or worse rather than to clarify a real distinction.

**Mitigation:** Disclose selection criteria, include fair baselines, and review against counterexamples.

### Overloaded comparison

**Cause:** Too many alternatives or dimensions are included at once.

**Mitigation:** Group dimensions, stage the comparison, filter by audience task, or use progressive disclosure.

### Label substitution

**Cause:** Labels replace criteria, so people memorize names without understanding distinguishing features.

**Mitigation:** Pair labels with criteria, examples, non-examples, and application exercises.

### Context stripping

**Cause:** Items are made comparable by removing essential background, uncertainty, scale, or source information.

**Mitigation:** Preserve context notes, uncertainty markers, and source references where they affect interpretation.

### Contrast fatigue

**Cause:** Everything is highlighted or differentiated, so no distinction remains meaningful.

**Mitigation:** Reserve high-salience contrast for consequential differences and maintain a contrast threshold.

### Boundary brittleness

**Cause:** The distinction works for familiar examples but fails on edge cases.

**Mitigation:** Use boundary-case testing and revise the contrast dimensions when misclassification recurs.

The most important warning is that contrast has persuasive force. A bad contrast can make the wrong difference feel obvious. Reviewers should ask whether the comparison set, dimensions, examples, and labels would still look fair if their selection criteria were made explicit.

prose_neighbor_distinctions:
### strategic_juxtaposition
Strategic juxtaposition places elements together to reveal a relation, which may be difference, similarity, contradiction, analogy, or emergent meaning. Contrastive differentiation is narrower: it clarifies the differences that distinguish confusable alternatives.

### focal_emphasis_design
Focal emphasis makes a priority element stand out so attention or resources flow toward it. Contrastive differentiation compares alternatives so the audience can tell them apart.

### canonical_classification
Classification assigns cases to categories. Contrastive differentiation helps define or teach the distinctions that make classification reliable, especially at boundaries.

### interaction_effect_mapping
Interaction effect mapping tests how factors change one another's effects when combined. Contrastive differentiation clarifies visible or represented differences among alternatives.

### tradeoff_surface_mapping
Tradeoff surface mapping maps how choices move across competing dimensions. Contrastive differentiation can reveal differences on selected dimensions but does not model the whole tradeoff landscape.

### priority_based_admission
Priority-based admission decides what gets access or attention. Contrastive differentiation may clarify priority-relevant differences, but it does not allocate by itself.

### communication_design
Communication design may package messages for comprehension or persuasion. Contrastive differentiation is specifically the structural act of making consequential differences explicit.

A practical test: if the main question is “what relation appears when these are put together?”, the neighbor is often Strategic Juxtaposition. If the question is “which one should receive attention?”, the neighbor is often Focal Emphasis Design. If the question is “what category does this belong to?”, a classification archetype may be primary. If the question is “what exact difference makes these confusable things not the same?”, use Contrastive Differentiation.

prose_cross_domain_examples:
### education and concept learning

A lesson pairs a valid example, a near non-example, and an edge case to show what makes a concept apply. The intervention clarifies membership by making the distinguishing feature visible across cases.

### medicine and incident response

A diagnostic guide contrasts plausible causes by symptoms, tests, onset pattern, and risk signs that distinguish them. The task is to differentiate confusable explanations before choosing action.

### procurement and product selection

A comparison matrix distinguishes software options by integration burden, support model, security requirements, and long-term lock-in. The options may look similar until their decision-relevant differences are represented in a shared frame.

### dashboards and safety systems

Operational states are encoded so warning, critical, and informational statuses are perceptually and procedurally distinct. Misreading a status causes different action, so the state differences must be made salient and usable.

### organizational design

A role-boundary guide contrasts the responsibilities of product, project, program, and operations roles. Role confusion is reduced by clarifying differences in authority, scope, handoffs, and decision rights.

### policy and compliance

A compliance handbook contrasts reportable incidents with similar non-reportable events using threshold examples and exception notes. The archetype clarifies a classification boundary that drives reporting behavior.

### law and argumentation

A legal memo contrasts a present case with precedent by identifying the facts that materially distinguish them. The relevant reasoning depends on making a difference explicit rather than merely placing cases together.

### Extended Example

A team keeps confusing two customer support paths: ordinary troubleshooting and security incident escalation. Both begin with customer reports, both involve technical staff, and both require documentation, so support agents route many cases inconsistently. Contrastive differentiation starts by naming the confusion, then defines the comparison set: routine defect, suspicious account activity, confirmed security incident, and false alarm. The team selects contrast dimensions: evidence type, urgency, privacy risk, required notification, owner, and escalation threshold. It creates paired examples and a compact contrast table that explains the distinguishing features. The guide includes boundary cases where a normal bug could become a security issue and states what agents should do next for each category. After rollout, the team audits misrouted cases and revises the examples. The intervention is not merely a new table; it is a structured clarification of the differences that determine routing and responsibility.

prose_non_examples:
### A graphic uses high color contrast simply to look dramatic.
There is no confusable alternative, task-relevant distinction, or action link.

### A ranked admissions queue sorts applicants after all criteria are already clear.
The central intervention is allocation or ordering, not difference clarification.

### A factorial experiment estimates whether two interventions interact non-additively.
That is interaction_effect_mapping; contrastive differentiation may display results but does not perform the interaction analysis.

### A museum places two artifacts side by side to evoke open-ended meaning without specifying a difference to use.
That is closer to strategic_juxtaposition unless a specific distinction is being clarified.

### A brand declares itself unique without explaining how it differs from substitutes.
Assertion of uniqueness is not contrastive differentiation unless the relevant distinctions are made explicit and credible.

- A side-by-side display that evokes a mood but does not clarify any task-relevant difference.

- A colorful warning label applied to every item equally.

- A classification algorithm that assigns categories without making the distinguishing criteria inspectable.

- A product brochure that claims superiority without specifying the comparison set or dimensions.

- A before/after photo that implies improvement while hiding changes in lighting, scale, or context.

prose_tradeoffs:
### Clarity versus completeness
A sharp contrast helps people decide or learn, but it can omit exceptions, overlap, or nuance if overcompressed.

### Salience versus fairness
Making differences vivid can improve recognition, but it can also exaggerate selected differences or hide shared context.

### Simplicity versus boundary accuracy
Binary contrasts are easy to remember, while real cases may involve gradients, hybrids, or multiple categories.

### Task relevance versus generality
A contrast tuned to one task may not transfer to another task without reselecting dimensions.

### Guided interpretation versus open exploration
Strongly cued contrasts reduce ambiguity but can narrow what people notice.

### Distinctiveness versus cohesion
Differentiating roles, options, or identities can reduce confusion but may fragment a system if shared responsibilities or commonalities are ignored.

The general tradeoff is that contrast clarifies by reducing and organizing information. That reduction is valuable only when the selected dimensions are fair, relevant, and revisable.

prose_invariants_to_preserve: The comparison must remain relevant to the confusion being solved. The contrast dimensions must matter for the task, not merely for persuasion or aesthetics. Distinguishing features must be specific enough to apply to new cases. Context must remain visible when removing it would change interpretation. The representation must not imply a false dichotomy when hybrid, ambiguous, or overlapping cases exist. Finally, the clarified difference must have a downstream use: a decision, diagnosis, classification, escalation, learning outcome, or revision path.

prose_target_outcomes: The archetype should reduce mistaken substitutions and unresolved ambiguity. A successful draft of the distinction lets people explain what separates nearby alternatives, apply the distinction to new cases, and act consistently on the clarified difference. In operational settings, this can mean faster escalation and fewer false routes. In learning settings, it means better transfer to near misses. In decision settings, it means less time spent comparing irrelevant features and more attention to the differences that determine fit.

prose_parameter_dimensions:
- **Comparison set size:** A small set improves clarity; a larger set improves coverage but can overwhelm.
- **Dimension granularity:** Coarse dimensions support quick decisions; fine-grained dimensions support expert judgment and edge cases.
- **Contrast strength:** Strong perceptual or textual contrast improves recognition, but excessive contrast can distort importance.
- **Context depth:** Minimal context speeds comparison; richer context reduces misleading simplification.
- **Boundary-case density:** More near misses improve transfer but can make a beginner-facing explanation feel complex.
- **Decision linkage:** Some contrasts only teach interpretation; others must trigger routing, escalation, admission, rejection, or revision.
- **Update cadence:** Stable concepts may need infrequent review, while operational states, product options, and policies may require regular revision.

prose_variants_and_near_names:
The variants preserve recurring uses without promoting every method or artifact into a top-level archetype.

### Concept Boundary Differentiation

Clarifies the boundary between similar concepts by showing which features determine membership and non-membership. It remains under the parent because It uses the same logic of selecting comparison cases, naming contrast dimensions, representing differences, and linking the distinction to interpretation.

### Option Differentiation

Clarifies how available options differ on the dimensions that matter for selection or prioritization. It remains under the parent because It still works by making relevant differences explicit rather than by allocating resources, admitting work, or optimizing a portfolio by itself.

### Diagnostic Differentiation

Distinguishes among plausible causes, states, or explanations by the observations that separate them. It remains under the parent because It is still an implementation of contrastive differentiation unless it becomes a full causal diagnosis workflow with distinct detection, testing, and updating logic.

### Signal / State Differentiation

Makes an important signal, state, severity, or status visibly different from confusable background conditions. It remains under the parent because The core intervention remains difference amplification, not attention budgeting or alert admission.

### Identity / Role Differentiation

Clarifies how roles, identities, brands, responsibilities, or positions differ from nearby alternatives. It remains under the parent because The intervention still relies on contrast dimensions, distinguishing features, and representation rather than a full governance or identity-system design.

### Collapsed or Mechanism-Level Names

Contrast tables, before/after comparisons, before/after views, visual contrast encodings, and A/B comparisons are mechanisms. They can implement the archetype, but they do not define the full intervention logic. Visual hierarchy and salience hierarchy should remain closer to Focal Emphasis Design or component-level attention design unless a future review establishes a distinct archetype.

domain: brand

example: A positioning document contrasts a product with substitutes by target customer, promise, and non-goals.

failure_modes: The distinction becomes territorial or exclusionary instead of clarifying action.

failure_modes: The contrast exaggerates differences that are not operationally meaningful.

essence_one_line: Make individual contributions visible enough that group work does not hide effort, free-riding, or overload.

compression_statement: When group output masks individual contribution, design calibrated visibility and accountability so effort, dependency, hidden enabling work, free-riding, and overload can be recognized fairly and adjusted before resentment or disengagement accumulates.

core_intuition: A shared output can make contribution ambiguous. Ambiguity may protect collaboration in small doses, but it also lets some work disappear, lets some people coast, and lets others become overloaded without recognition. This archetype works by making the right contribution signals visible to the right people, with enough context and safety that visibility supports fairness and coordination rather than blame.

canonical_formula: pooled group output + defined contribution units + calibrated visibility mechanism + ownership record + context-aware review + recognition/rebalancing + safety boundary -> fairer contribution, less hidden overload, and less free-riding

structural_problem: A group produces a shared output, but individual contribution, dependency, support work, or overload is hidden inside the pooled result. Because contribution is not legible, people may under-contribute, high contributors may be overloaded or unrecognized, coordination gaps may persist, and managers or peers may misread group performance.

trigger_conditions: A group output is evaluated as a whole while the distribution of work inside the group is unclear.

trigger_conditions: Some contributions are visible because they are final deliverables, while preparation, coordination, review, maintenance, mentoring, prevention, or support work is hidden.

trigger_conditions: Participants suspect free-riding, but available evidence cannot distinguish low effort from blockers, capacity constraints, skill gaps, or invisible enabling work.

trigger_conditions: A few people repeatedly absorb urgent work, integration tasks, or cleanup without recognition or rebalancing.

trigger_conditions: The team needs contribution accountability, but direct monitoring would create fear, privacy harm, or performative work.

trigger_conditions: Reward, grading, staffing, or recognition decisions depend on contribution patterns that are currently hard to observe.

symptoms: Group members say some people are carrying the work, but no one can show the pattern in a fair and contextual way.

symptoms: The final output looks successful while contributors report resentment, burnout, hidden coordination labor, or quiet disengagement.

symptoms: People optimize visible tasks while neglecting review, handoffs, quality control, documentation, or support work.

symptoms: Managers or evaluators over-credit the most visible contributor and under-credit those doing maintenance, mentoring, integration, or prevention.

symptoms: Peer trust erodes because contribution expectations are implicit and contribution evidence is anecdotal.

symptoms: The group alternates between ignoring contribution imbalance and overcorrecting through punitive surveillance or public blame.

root_tension: Collaboration benefits from shared ownership, mutual support, and flexible contribution, but fairness and coordination require enough visibility to know who is contributing, who is blocked, who is overloaded, and where recognition or rebalancing is needed.

anti_signatures: The output is genuinely indivisible and individual contribution cannot be meaningfully separated without destroying the work or violating trust.

anti_signatures: The main problem is unclear decision authority or emergency action ownership rather than hidden contribution over time.

anti_signatures: The group already has accurate, trusted, context-rich contribution visibility and the remaining issue is resource scarcity, strategy, or skill.

anti_signatures: Visibility would expose sensitive personal information, protected activity, or vulnerable contributors without a compelling coordination or fairness need.

anti_signatures: The proposed system would primarily rank, shame, or surveil people rather than support recognition, rebalancing, and accountability.

structural_intervention: Define meaningful contribution units, create a calibrated visibility mechanism, link work to ownership and context, review patterns for overload or free-riding, recognize visible and invisible work, and preserve a safety boundary that prevents visibility from becoming surveillance or blame theater.

action_logic: Identify the group output, shared workflow, or pooled responsibility where contribution is currently hidden or contested.

action_logic: Define contribution units that reflect value-producing work, including final deliverables, coordination, review, handoff, support, prevention, maintenance, and learning contributions.

action_logic: Choose a visibility mechanism that makes contribution legible to the smallest appropriate audience and for an explicit purpose.

action_logic: Connect contribution records to context: dependencies, blockers, role expectations, capacity, skill level, interruptions, and shared ownership.

action_logic: Use a review cadence to detect uneven contribution, hidden overload, unrecognized enabling work, and possible free-riding.

action_logic: Convert findings into recognition, support, rebalancing, coaching, escalation, or role redesign rather than automatic punishment.

action_logic: Maintain safety boundaries for privacy, consent, appeal, data minimization, and anti-gaming so the system supports collaboration instead of performative visibility.

decision_rules: Use this archetype when pooled group output hides contribution patterns that matter for fairness, workload balance, accountability, or learning.

decision_rules: Select visibility units based on value and coordination need, not merely on what is easiest to count.

decision_rules: Treat contribution data as a prompt for inquiry before judgment; uneven patterns may indicate blockers, overload, role mismatch, or hidden work.

decision_rules: Make visibility proportional: the audience, frequency, and granularity should match the coordination problem and safety risk.

decision_rules: Pair visibility with recognition or rebalancing; do not expose contribution information without a constructive response path.

decision_rules: Review the visibility mechanism for gaming, chilling effects, bias, privacy harm, and erosion of psychological safety.

target_invariants: Contribution visibility must preserve collaboration rather than fragmenting every shared task into competitive individual accounting.

target_invariants: The system must recognize hidden enabling work as well as final deliverables.

target_invariants: Visibility must remain contextual and contestable; raw counts alone are not treated as truth.

target_invariants: The visibility mechanism must not become unrestricted surveillance, coercive ranking, or public shaming.

target_invariants: Findings must connect to support, recognition, rebalancing, or accountability actions that participants understand.

expected_outcomes: Reduced free-riding and responsibility hiding in group work.

expected_outcomes: Earlier detection of hidden overload, bottlenecks, and unrecognized support burdens.

expected_outcomes: Fairer recognition of contribution, including coordination, review, maintenance, mentoring, and prevention work.

expected_outcomes: Clearer expectations about shared and individual responsibilities inside collaborative output.

expected_outcomes: Improved trust because contribution concerns can be discussed with evidence and context rather than rumor.

expected_outcomes: Better rebalancing of workload and support before resentment, burnout, or disengagement hardens.

prose_essence:
Contribution Visibility Design is the pattern of making contribution inside shared work legible enough to support fairness, accountability, workload balance, and recognition. It applies when a pooled group output hides who contributed what, who is blocked, who is carrying hidden enabling work, and who may be relying on others without contributing proportionally.

The archetype is not “track everyone more.” Its essential move is calibrated visibility: define meaningful contribution units, choose a proportionate visibility mechanism, interpret contribution signals with context, and connect findings to recognition, rebalancing, support, or accountability. The safety boundary is part of the archetype, not an optional add-on.

prose_when_to_use:
Use this archetype when group work hides contribution patterns that matter. Common triggers include group projects where final output masks uneven work, operations teams where the same people absorb urgent load, volunteer systems where some people quietly carry coordination work, and research or product teams where review, maintenance, mentoring, and integration are under-recognized.

It is especially useful when rumors about free-riding or resentment about overload are growing but the group lacks fair evidence. It is also useful when reward, grading, staffing, or recognition decisions depend on contribution patterns that cannot be observed from the final output alone.

Do not use it as a shortcut for micromanagement. If the real problem is unclear decision authority, use a decision-rights or responsibility-assignment pattern. If the proposed visibility would expose vulnerable participants or create public shaming, redesign the safety boundary before proceeding.

prose_structural_problem:
The structural problem is pooled output with hidden contribution. In group work, the final product often compresses many different activities into one result: analysis, coordination, review, emotional support, cleanup, stakeholder communication, maintenance, and integration. Some of those activities are visible; many are not.

This creates two linked distortions. First, under-contribution can be hidden because the group output still appears complete. Second, overload and invisible enabling work can be hidden because high contributors compensate for gaps without being recognized. Over time, trust erodes because people rely on anecdotes, resentment, and reputation rather than contextual evidence.

prose_intervention_logic:
The intervention begins by defining what counts as contribution in the specific context. Contribution units should include the work that actually creates value, not merely the work that is easiest to count. A software team may include code review and incident support. A research team may include data curation, supervision, methodology, and writing. A volunteer group may include follow-up, handoffs, and training.

Next, the group chooses a calibrated visibility mechanism. The mechanism might be a shared board, contribution log, authorship matrix, peer evaluation process, workload heatmap, or contribution review meeting. The right mechanism is the one that makes the relevant contribution pattern visible to the smallest appropriate audience for the clearest constructive purpose.

The final move is response. Contribution visibility should lead to recognition, rebalancing, support, coaching, role redesign, or accountability. It should not stop at exposure. A visibility system that reveals overload but does not change workload merely makes unfairness more visible.

prose_key_components:
### Contribution Unit

A contribution unit defines what kind of work should be visible. Good units reflect actual value: deliverables, coordination, review, maintenance, mentoring, prevention, stakeholder communication, or handoff work. Bad units track only what is easy to count, such as messages sent or hours online.

```yaml
component:
  slug: contribution_unit
  name: Contribution Unit
  role: Defines the kind of contribution that should be visible.
  notes: The unit should match meaningful work rather than convenient activity proxies.
```

### Visibility Mechanism

The visibility mechanism is the channel through which contribution becomes legible. It may be a board, log, dashboard, matrix, review ritual, or peer feedback process. It should be selected for purpose and proportionality, not for maximum observability.

```yaml
component:
  slug: visibility_mechanism
  name: Visibility Mechanism
  role: Makes contribution information legible to the right audience.
  notes: Visibility should be sufficient for fairness and coordination without becoming surveillance.
```

### Ownership Record

An ownership record links work, decisions, deliverables, handoffs, or support actions to contributors. It prevents shared output from erasing who carried responsibilities, while still allowing joint ownership where work is genuinely shared.

```yaml
component:
  slug: ownership_record
  name: Ownership Record
  role: Links work items and responsibilities to contributors.
  notes: Ownership records should include shared ownership, handoffs, and invisible enabling work.
```

### Effort Recognition

Effort recognition converts visible contribution into credit, support, compensation, feedback, or role adjustment. Without recognition, visibility can feel extractive: people become more observable but not more fairly treated.

```yaml
component:
  slug: effort_recognition
  name: Effort Recognition
  role: Turns visible contribution into appropriate acknowledgement or response.
  notes: Recognition should include coordination, review, maintenance, mentoring, and prevention work.
```

### Overload or Free-Ride Monitor

The overload or free-ride monitor looks for uneven contribution patterns. It should trigger inquiry before blame because uneven effort may reflect hidden blockers, unclear expectations, capacity constraints, skill gaps, or unrecognized support work.

```yaml
component:
  slug: overload_or_free_ride_monitor
  name: Overload or Free-Ride Monitor
  role: Detects uneven contribution, hidden overload, and possible free-riding.
  notes: The monitor should trigger contextual review rather than automatic punishment.
```

### Visibility Safety Boundary

The safety boundary defines what information is exposed, to whom, for what purpose, and under what safeguards. It protects privacy, consent, appeal, data minimization, and psychological safety.

```yaml
component:
  slug: visibility_safety_boundary
  name: Visibility Safety Boundary
  role: Prevents contribution visibility from becoming surveillance or public shaming.
  notes: The boundary is an invariant of the archetype, not an optional compliance detail.
```

### Contribution Context Note

Contribution context notes explain blockers, dependencies, interruptions, role expectations, and hidden enabling work. They prevent raw contribution signals from being interpreted as simple proof of effort or character.

```yaml
component:
  slug: contribution_context_note
  name: Contribution Context Note
  role: Adds contextual interpretation to contribution records.
  notes: Context notes reduce false precision and blame based on raw activity traces.
```

### Review and Rebalancing Cadence

The cadence creates a recurring moment to discuss contribution patterns and adjust work. It keeps the system from becoming a passive dashboard and makes rebalancing part of normal collaboration.

```yaml
component:
  slug: review_and_rebalancing_cadence
  name: Review and Rebalancing Cadence
  role: Reviews contribution patterns and adjusts assignments or support.
  notes: The cadence should be lightweight enough to sustain and consequential enough to matter.
```

prose_common_mechanisms:
### Contribution Tracking Board

```yaml
mechanism:
  slug: contribution_tracking_board
  name: Contribution Tracking Board
  mechanism_type: interface
  role: Displays work units, owners, status, blockers, and handoffs.
```

A contribution tracking board implements the archetype by making contribution units visible during work. It is not the archetype itself because a board without context, recognition, and safety boundaries can become a passive task list or surveillance dashboard.

### Team Work Board

```yaml
mechanism:
  slug: team_work_board
  name: Team Work Board
  mechanism_type: interface
  role: Shows who is doing what, where work is blocked, and where support is needed.
```

A team board is useful when coordination and workload balance are central. It works best when it includes hidden work categories and blocked-work signals rather than only visible deliverables.

### Peer Evaluation Process

```yaml
mechanism:
  slug: peer_evaluation_process
  name: Peer Evaluation Process
  mechanism_type: test_or_assessment
  role: Collects structured peer observations of contribution quality and collaboration.
```

Peer evaluation is a mechanism under this archetype. It can reveal contribution that supervisors do not observe, but it needs safeguards against popularity bias, retaliation, clique dynamics, and over-weighting charisma.

### Individual Deliverable Contract

```yaml
mechanism:
  slug: individual_deliverable_contract
  name: Individual Deliverable Contract
  mechanism_type: document
  role: Breaks a group output into named deliverables or responsibility slices.
```

This mechanism creates visibility through partitioning. It should not be used to fragment work artificially or discourage integration quality.

### Work Log or Activity Trace

```yaml
mechanism:
  slug: work_log_or_activity_trace
  name: Work Log or Activity Trace
  mechanism_type: document
  role: Records contribution activity over time, including invisible enabling work.
```

A work log helps reconstruct contribution history. It is safe only when the group treats it as contextual evidence, not as raw proof of worth.

### Shared Task Ownership Protocol

```yaml
mechanism:
  slug: shared_task_ownership_protocol
  name: Shared Task Ownership Protocol
  mechanism_type: protocol
  role: Clarifies how jointly owned work is split, coordinated, reviewed, and credited.
```

This mechanism preserves collaboration while preventing shared ownership from becoming invisible ownership.

### Contribution Review Meeting

```yaml
mechanism:
  slug: contribution_review_meeting
  name: Contribution Review Meeting
  mechanism_type: ritual
  role: Reviews contribution patterns, blockers, invisible work, uneven load, and recognition gaps.
```

The review meeting turns visibility into action. It should produce rebalancing, support, recognition, or role clarification rather than merely naming problems.

### Workload Heatmap

```yaml
mechanism:
  slug: workload_heatmap
  name: Workload Heatmap
  mechanism_type: metric_or_dashboard
  role: Visualizes work concentration, overload risk, support needs, or repeated under-contribution.
```

A workload heatmap implements the workload-visibility variant. It is useful for spotting hidden overload, but it becomes harmful if treated as a ranking device.

### Credit Taxonomy or Authorship Matrix

```yaml
mechanism:
  slug: credit_taxonomy_or_authorship_matrix
  name: Credit Taxonomy or Authorship Matrix
  mechanism_type: template
  role: Names contribution categories so recognition is not limited to the most visible output.
```

This mechanism is especially useful for research, maintenance, open-source, and community work where final credit can erase hidden enabling contributions.

prose_failure_modes:
The most common failure mode is surveillance drift. A tool built to support fairness gradually becomes a mechanism for continuous monitoring or coercive ranking.

A second failure mode is wrong-unit measurement. The system tracks visible activity instead of meaningful contribution, causing people to optimize the metric rather than the work.

A third failure mode is blame before inquiry. Uneven contribution patterns are treated as personal failure without checking blockers, role expectations, access, capacity, or hidden work.

A fourth failure mode is recognition without rebalancing. The system identifies overload but does not change staffing, priorities, or authority, which can make the overloaded contributors feel even more exploited.

A fifth failure mode is peer-evaluation distortion. Peer input can reveal important information, but it can also encode popularity, retaliation, bias, or clique loyalty.

prose_neighbor_distinctions:
Contribution Visibility Design is distinct from Responsibility Assignment for Action. Responsibility Assignment asks who owns an action when responsibility might diffuse; Contribution Visibility asks how ongoing group work can make contribution, overload, and hidden support visible.

It is distinct from Decision Rights Clarification, which concerns who has authority to decide. Contribution visibility concerns who contributes what and how work is distributed.

It is distinct from Task Interdependence Mapping. A dependency map shows how tasks relate; contribution visibility uses that understanding to support recognition, accountability, and workload balance.

It is distinct from Performance Management. It may inform evaluation, but its primary purpose is to design collaborative visibility and fairness inside group output.

It is also distinct from Psychological Safety Enablement. Psychological safety is a key guardrail because visibility can chill candor, but the transformation here is contribution legibility.

prose_cross_domain_examples:
In group learning, students use contribution units, milestone check-ins, and structured peer reflection so the final group grade does not erase uneven work or hidden support.

In software development, a team tracks review load, documentation, incident support, and integration work alongside feature delivery, preventing commit count from becoming the only visible contribution.

In volunteer operations, a mutual-aid group uses shift boards and handoff logs to see who is carrying urgent requests and where backup is needed.

In research collaboration, an authorship matrix records conceptualization, methods, data curation, analysis, writing, review, supervision, and administration before credit decisions are made.

In cross-functional delivery, a team reviews who owns handoffs, stakeholder updates, risk management, and cleanup work so the same people are not silently carrying integration.

prose_non_examples:
A keystroke tracker or online-status dashboard is not Contribution Visibility Design. It measures activity without meaningful contribution units, context, or safety.

A public leaderboard ranking contributors by task count is not this archetype if it creates competition, shame, or gaming rather than recognition and rebalancing.

A generic performance review is not this archetype unless it addresses pooled group output and hidden collaborative work.

A task list with names attached is not enough. Without contribution context, review, recognition, rebalancing, and safety boundaries, it is only a task-management artifact.

prose_tradeoffs:
The main tradeoff is visibility versus safety. More visibility can improve accountability, but too much can create surveillance, gaming, public shame, and performative busyness.

Another tradeoff is individual accountability versus collective ownership. The archetype should make contribution legible without destroying the mutual support that makes collaboration valuable.

A third tradeoff is measurement simplicity versus contribution truth. Easy metrics are attractive, but the most important work is often qualitative, preventive, or relational.

prose_invariants_to_preserve:
The system must preserve collaboration. Contribution visibility should not turn every shared task into a competition for individual credit.

The system must preserve context. Raw counts, activity traces, or peer scores should never be treated as complete truth.

The system must preserve safety. Visibility should not expose sensitive personal information, create public shame, or punish help-seeking.

The system must preserve recognition of invisible work. If the mechanism only credits final deliverables, it fails one of the main reasons to use the archetype.

The system must preserve actionability. Visibility should lead to recognition, support, rebalancing, coaching, or accountability; otherwise it becomes observation without repair.

prose_target_outcomes:
A successful implementation reduces hidden free-riding and hidden overload at the same time. It gives teams evidence to discuss contribution fairly and makes it easier to rebalance work before resentment accumulates.

It also improves recognition. People doing coordination, review, maintenance, mentoring, prevention, documentation, and support work become visible enough to be credited and supported.

Finally, it improves trust. Instead of relying on rumor or resentment, the group has a shared way to understand contribution patterns and act on them.

prose_parameter_dimensions:
The first tuning dimension is granularity. Fine-grained contribution units can reveal hidden work, but they increase burden and gaming risk. Coarse-grained units are easier to maintain, but they may miss important inequalities.

The second dimension is audience. Some visibility belongs within the team; some belongs to a manager, instructor, or governance body; some should remain private to a reviewer. The audience should be no broader than the coordination or fairness purpose requires.

The third dimension is cadence. Real-time visibility helps coordination but can create monitoring anxiety. Periodic reviews reduce surveillance risk but may catch overload too late.

The fourth dimension is evaluative weight. Contribution visibility can inform recognition, grading, compensation, staffing, or learning feedback, but the higher the stakes, the stronger the safeguards must be.

The fifth dimension is context depth. Raw signals are cheap and dangerous. Context-rich signals take more effort but produce fairer interpretation.

prose_variants_and_near_names:
Workload Visibility Design focuses on hidden overload, bottlenecks, and support needs. It is useful when high contributors are silently absorbing too much work.

Peer Contribution Calibration uses structured peer observation to reveal contribution quality and collaboration. It should remain a mechanism-family variant unless later review finds a separate archetype.

Invisible Work Recognition focuses on work that final outputs often erase: maintenance, mentoring, review, coordination, documentation, prevention, and care-like support.

Individual Deliverable Partitioning creates visibility by decomposing group output into named work packages. It is useful only when partitioning does not destroy necessary collaboration.

Near names include effort visibility design, social loafing countermeasure, contribution tracking, peer evaluation, team board, and workload visibility. These names should generally point back to the parent archetype or to one of its variants or mechanisms.

Workload Visibility Design

short_definition: A variant focused on detecting overload, bottlenecks, and hidden support burdens rather than only detecting free-riding.

distinctive_feature: The visibility target is load concentration and support need, not individual credit alone.

distinct_from_parent: The parent covers contribution visibility broadly; this variant emphasizes workload balance and overload prevention.

still_same_parent_because: It still changes group performance by making otherwise hidden contribution patterns legible and reviewable.

use_when: A few contributors are silently carrying a disproportionate share of the work.

use_when: Group output appears healthy while fatigue, blockers, or dependency concentration are hidden.

use_when: Managers or peers need to rebalance work before burnout, resentment, or quality decline occurs.

example_domains:
operations
software teams
healthcare teams
volunteer systems

domain: Operations

example: A dispatch team reviews a workload heatmap to spot people repeatedly carrying unresolved escalations.

domain: Software

example: A team checks review and incident-support load, not just feature tickets, before assigning more work.

failure_modes: Load dashboards become performance surveillance instead of rebalancing support.

failure_modes: Visible overload is acknowledged but not backed by staffing, prioritization, or role changes.

Peer Contribution Calibration

short_definition: A variant using structured peer observations to calibrate contribution visibility where direct observation is incomplete.

distinctive_feature: The information source is peer observation rather than an artifact trail or manager review.

distinct_from_parent: The parent does not require peer evaluation; this variant uses peer feedback as one controlled visibility channel.

still_same_parent_because: The intervention still makes contribution patterns visible enough to support fair recognition, support, and rebalancing.

use_when: Participants see each other's collaboration, preparation, responsiveness, and support work better than a formal supervisor does.

use_when: Group grading, review, bonus allocation, or learning feedback risks treating pooled output as equal contribution.

use_when: Peer input can be collected with safeguards against popularity contests, retaliation, or clique bias.

example_domains:
education
project teams
professional training
collaborative research

domain: Education

example: Students submit structured peer contribution reflections that inform group-project feedback without automatically determining grades.

domain: Training

example: A cohort uses peer observations to identify who is preparing, coaching others, and carrying coordination work.

failure_modes: Peer scoring becomes popularity ranking or retaliation.

failure_modes: The form rewards visible charisma while missing quiet preparation, quality control, or care work.

Invisible Work Recognition

short_definition: A variant focused on surfacing maintenance, coordination, review, mentoring, prevention, emotional labor, and other work hidden behind final deliverables.

distinctive_feature: The visibility target is often non-deliverable work that prevents failure or enables others.

distinct_from_parent: The parent covers all contribution visibility; this variant is specifically about crediting hidden enabling work.

still_same_parent_because: It still uses contribution visibility to improve fairness, accountability, and group coordination.

source_primes: equity feedback transparency

use_when: Some contributors create value through enabling work that standard output metrics do not capture.

use_when: Recognition, promotion, credit, or resource allocation overweights visible deliverables and underweights support work.

use_when: Unrecognized maintenance and coordination burdens are creating resentment or inequity.

example_domains:
research collaboration
open-source maintenance
community organizations
operations

domain: Research

example: A project records data curation, statistical review, project administration, and supervision alongside authorship.

domain: Open source

example: Maintainers track triage, review, documentation, and release work rather than only merged code.

failure_modes: The taxonomy becomes performative bureaucracy with no connection to actual credit or support.

failure_modes: People game category labels rather than improving collaboration.

Individual Deliverable Partitioning

short_definition: A variant that partitions group output into identifiable contributor-owned deliverables or work packages.

distinctive_feature: Visibility is created by decomposition of the shared output into named contribution units.

distinct_from_parent: The parent can also use peer feedback, work logs, dashboards, or review rituals; this variant relies on deliverable partitioning.

still_same_parent_because: Partitioning is one way to make contribution legible; it is not the entire archetype.

use_when: The group output is pooled, but work can be decomposed into meaningful responsibility slices.

use_when: The team needs enough separability to evaluate contribution without destroying collaboration.

use_when: Handoffs, dependencies, or quality review require named ownership of work packages.

example_domains:
group learning
consulting projects
product development
policy drafting

domain: Consulting

example: A proposal team names owners for evidence synthesis, client interviews, pricing, narrative, and review rather than crediting only the final deck.

failure_modes: Partitioning destroys useful collaboration by forcing artificial individual slices.

failure_modes: People optimize their own slice while neglecting integration quality.

essence_one_line: Make an experimental effect interpretable by specifying exactly what the treatment is being compared against and keeping that comparator realistic, ethical, stable, and uncontaminated.

compression_statement: A causal-comparison design pattern that turns an implicit “not treatment” into an explicit control condition: state the estimand, define the comparator arm, justify why it is the relevant counterfactual alternative, align measurement and timing, guard against contamination and expectancy differences, document ethical constraints, and interpret results only as the specified treatment-versus-control contrast.

core_intuition: A treatment effect is not a property of a treatment alone. It is a difference between what happened under the treatment and what would have happened under another condition. If that other condition is vague, artificial, unethical, contaminated, or unlike the real alternative decision-makers face, the result may be statistically neat but substantively meaningless. Control-condition specification makes the counterfactual comparator visible before the study begins.

canonical_formula: Interpretable effect ≈ explicit estimand + justified comparator condition + matched measurement + contamination guardrails + ethical feasibility + contrast-bounded interpretation.

structural_problem: An experiment or evaluation needs to isolate an intervention effect, but the “control” is underspecified, mislabeled, unrealistic, unstable, contaminated, or ethically unavailable. Without a well-defined comparator condition, the observed difference cannot be interpreted as a meaningful treatment effect, and the study may answer a question no stakeholder actually needs.

trigger_conditions: A study compares a new treatment, policy, product, message, workflow, or teaching method with some alternative condition.

trigger_conditions: The research question depends on a contrast: treatment versus placebo, standard care, waitlist, no treatment, usual practice, active comparator, sham procedure, or status quo.

trigger_conditions: Participants, units, sites, or users can receive more than one possible condition, or historical/external comparators are being considered.

trigger_conditions: The expected effect could be confounded by attention, time, measurement, provider behavior, placebo effects, exposure intensity, or background services.

trigger_conditions: The control group must remain credible to participants, implementers, reviewers, regulators, or decision-makers.

trigger_conditions: The ethical acceptability of withholding, delaying, or simulating an intervention must be evaluated.

trigger_conditions: Prior evidence or pilot design used an implicit baseline such as “business as usual” without documenting what that actually meant.

trigger_conditions: Adoption decisions require knowing whether the treatment beats the relevant realistic alternative, not merely an artificial weak comparator.

symptoms: The design says “control group” but does not say what participants receive, do not receive, believe, or experience.

symptoms: The comparator is “usual care” or “standard practice,” but actual usual care varies across sites, providers, or time.

symptoms: A placebo or sham condition fails to match the treatment in attention, credibility, burden, risk, or expectation.

symptoms: A no-treatment control creates a large artificial contrast that would not exist in real adoption decisions.

symptoms: Control participants gain access to the treatment, imitate treated participants, or receive spillover exposure.

symptoms: Outcome timing, measurement intensity, incentives, or follow-up contact differs between treatment and control conditions.

symptoms: Study reports overgeneralize from “treatment beats placebo” to “treatment beats current best alternative.”

symptoms: Ethics review questions whether withholding, delaying, or disguising the intervention is acceptable.

symptoms: Null or positive findings are uninterpretable because the control condition was too strong, too weak, unstable, or undocumented.

root_tension: The cleanest comparator for causal isolation is often not the most realistic or ethical comparator for decision-making. The design must balance internal validity, practical relevance, participant welfare, implementation feasibility, and interpretive clarity.

anti_signatures: The task is exploratory concept generation and no experimental contrast is being designed yet.

anti_signatures: The central problem is randomizing assignment rather than defining what each condition means; use controlled_randomization as the nearer neighbor.

anti_signatures: The central problem is checking whether randomization created similar groups; use baseline_covariate_balance_verification as the nearer neighbor.

anti_signatures: The central problem is reducing expectancy or observer bias after conditions are defined; use blinding_and_expectancy_bias_reduction as the nearer neighbor.

anti_signatures: The central problem is preventing or adjusting for third-variable distortion across the whole causal design; use confounder_control or design_stage_confounder_prevention as the nearer neighbor.

anti_signatures: The central problem is validating a system against a benchmark or gold standard rather than designing an experimental counterfactual; use comparative_benchmark_validation as the nearer neighbor.

anti_signatures: The comparator would require unethical deprivation, deception, or exposure to harm that cannot be justified or mitigated.

anti_signatures: The proposed “control” is merely a reporting label with no operational difference from the treatment condition.

structural_intervention: Install an explicit comparator-design step before experiment execution: define the target estimand, specify the control condition as an operational alternative, justify its relevance and ethics, align measurement and contact across arms, protect comparator integrity, and bind interpretation to the treatment-versus-control contrast actually tested.

action_logic: State the causal or evaluative question as a contrast: what intervention, for which units, compared with what alternative, under what conditions, and over what time horizon.

action_logic: List candidate control conditions: placebo, sham, no-treatment, waitlist, delayed treatment, standard care, usual practice, active comparator, attention control, dose comparator, or historical/external control.

action_logic: Select the comparator that best fits the decision while preserving internal validity, ethical acceptability, and feasibility.

action_logic: Define what control participants or units receive, do not receive, experience, know, and have measured.

action_logic: Match treatment and control arms on outcome measurement, follow-up timing, contact intensity, information access, incentives, and implementation support unless differences are part of the intended contrast.

action_logic: Document what background services, co-interventions, contamination channels, and spillovers are allowed, prohibited, or monitored.

action_logic: Check whether the comparator is too weak, too strong, too artificial, too heterogeneous, or too unstable for the study claim.

action_logic: Specify how results will be interpreted: superiority over placebo, incremental benefit over standard care, equivalence to an active comparator, effect of added component, or effect relative to no intervention.

action_logic: Record ethical constraints, participant protections, rescue criteria, access after trial, and conditions under which the control design must change.

action_logic: Report the control condition in enough detail that readers can reproduce the contrast and understand the limits of the conclusion.

decision_rules: Use standard-care or usual-practice control when the decision is whether to replace or add to the real existing alternative.

decision_rules: Use placebo or sham control when expectancy, ritual, contact, or nonspecific effects must be separated from the active treatment component and ethical conditions permit it.

decision_rules: Use active comparator control when withholding effective treatment would be unethical or when the decision concerns relative performance against an accepted option.

decision_rules: Use waitlist or delayed-treatment control when temporary withholding is ethically acceptable and eventual access is important.

decision_rules: Use attention control when participant contact, coaching, monitoring, or care intensity could itself produce the outcome.

decision_rules: Use multiple control arms when no single comparator can distinguish placebo, attention, standard care, dose, and active-mechanism effects.

decision_rules: Do not interpret treatment success against a weak comparator as success against a strong realistic alternative.

decision_rules: Treat heterogeneous “usual care” as a measurement object, not a black box; inventory and stratify it when variation matters.

decision_rules: Reject a control condition when it cannot be implemented consistently enough to support the intended contrast.

decision_rules: Re-specify the comparator when background practice, standard care, technology, policy, or ethics changes during the study.

target_invariants: The treatment-control contrast is explicit before outcome interpretation.

target_invariants: The control condition is operationally specified, not merely named.

target_invariants: The comparator is relevant to the actual decision or causal question.

target_invariants: Measurement, timing, and follow-up are aligned unless intentionally part of the contrast.

target_invariants: Control integrity is protected against contamination, spillover, and hidden co-interventions.

target_invariants: Participant welfare and ethical constraints are documented and monitored.

target_invariants: The conclusion is bounded to the comparator that was actually tested.

target_invariants: Changes to standard care, usual practice, or background exposure trigger review rather than silent drift.

expected_outcomes: Treatment effects become interpretable as defined contrasts rather than vague improvements over “nothing.”

expected_outcomes: Study reports can distinguish placebo effects, attention effects, standard-care comparisons, and active-mechanism effects.

expected_outcomes: Invalid or unethical comparators are identified before the experiment starts.

expected_outcomes: Contamination and spillover are easier to detect and manage.

expected_outcomes: Decision-makers can tell whether the result applies to adoption, replacement, add-on use, or mechanism testing.

expected_outcomes: Replication becomes easier because the comparison condition is reproducible.

expected_outcomes: Overclaiming is reduced because conclusions remain tied to the tested control condition.

prose_essence:
Control-condition specification makes the experimental comparator explicit. It asks: what is the treatment being compared with, what does that comparator actually contain, and what conclusion will the contrast support? The pattern prevents the word “control” from hiding an undefined, unrealistic, unethical, or unstable baseline.

The core idea is that an effect is a contrast, not a standalone property. A new therapy, policy, product flow, curriculum, or workflow can look effective against no treatment and still fail against standard practice. It can look ineffective against a strong active comparator and still be useful as an add-on. This archetype therefore treats comparator design as part of the intervention logic of experimental design, not as a minor reporting detail.

prose_tradeoffs: The strongest causal comparator is not always the most useful decision comparator. A placebo may be clean but unrealistic. Standard care may be relevant but heterogeneous. A sham may support blinding but raise ethical concerns. Multiple control arms may answer more questions but increase sample-size and operational burden. The archetype does not eliminate these tradeoffs; it forces them to be named before interpretation.

Placebo or Sham Control Specification

short_definition: Designs an inert or simulated comparator that matches the treatment experience while omitting the active component.

distinctive_feature: The comparator must mimic the treatment experience without delivering the active mechanism.

distinct_from_parent: The parent defines any control condition; this variant specifically handles placebo and sham credibility.

still_same_parent_because: It remains a comparator-specification problem rather than a separate intervention family.

use_when: Expectancy, ritual, sensory experience, or provider contact could drive outcomes.

use_when: A credible inert or sham comparator is ethically and practically feasible.

example_domains:
clinical trials
device trials
behavioral experiments

domain: Clinical trial

example: A placebo pill matches appearance and dosing schedule while omitting the active drug.

domain: Device trial

example: A sham procedure mimics setup and attention while avoiding the active stimulation.

failure_modes: The sham introduces its own active effect.

failure_modes: The placebo condition is unethical because effective treatment is withheld.

name: Active or Standard-Care Control Specification

short_definition: Defines a comparator using an accepted treatment, current standard, or real operational alternative.

distinctive_feature: The comparator is an active alternative rather than absence, placebo, or delay.

distinct_from_parent: The parent covers control specification generally; this variant emphasizes live alternatives and standard-care drift.

still_same_parent_because: It still defines the experimental contrast rather than performing general benchmark validation.

use_when: Withholding treatment or service is unethical or irrelevant.

use_when: The decision is whether the new option is better than, equivalent to, or additive to the current alternative.

example_domains:
medicine
education
public policy
operations

domain: Medicine

example: A new drug is compared against current standard therapy rather than placebo.

example: A new scheduling process is compared with the current production process under the same demand mix.

failure_modes: Standard care varies silently across sites.

failure_modes: The comparator becomes obsolete during the study.

failure_modes: The result is misreported as placebo-controlled evidence.

Waitlist or Delayed-Access Control

short_definition: Uses delayed access to create an initial comparison while preserving eventual access for the control group.

distinctive_feature: The comparator is defined by timing of access rather than permanent withholding.

distinct_from_parent: The parent covers all comparator conditions; this variant centers temporal sequencing and crossover risk.

still_same_parent_because: It is still a way of specifying the control condition for a treatment contrast.

use_when: Immediate access for everyone is not feasible, but eventual access is ethically or politically important.

use_when: A defined comparison window can be preserved before crossover.

example_domains:
education
therapy programs
social services
software rollouts

example: Schools receive a new curriculum in staggered waves so early and later cohorts can be compared.

failure_modes: Control participants change behavior while waiting.

failure_modes: Delayed access timing is too short for outcome detection.

Attention-Control Specification

short_definition: Equalizes contact, monitoring, encouragement, or interpersonal attention while withholding the active content.

distinctive_feature: The comparator controls for attention and contact rather than only for treatment absence.

distinct_from_parent: The parent specifies any control condition; this variant controls nonspecific social or attention effects.

still_same_parent_because: It remains a comparator-definition variant rather than a full independent archetype.

use_when: Human attention or monitoring could plausibly cause the outcome.

use_when: The treatment includes coaching, counseling, provider contact, reminders, or motivational support.

example_domains:
behavioral health
coaching
education
workplace training

domain: Behavioral health

example: Control participants receive neutral wellness calls matching frequency and duration of coaching sessions.

failure_modes: The attention control becomes an active intervention.

failure_modes: Contact intensity is not actually matched.

failure_modes: Participants perceive one condition as more credible.

name: External or Historical Control Specification

short_definition: Uses non-concurrent or external comparator data when direct concurrent controls are infeasible, with explicit comparability constraints.

distinctive_feature: Comparator risk comes from temporal, measurement, and selection mismatch.

distinct_from_parent: The parent assumes an experimental comparator can often be assigned; this variant handles high-risk nonconcurrent comparison.

still_same_parent_because: It still specifies the comparator against which an intervention claim is interpreted.

use_when: Concurrent controls are impossible, unethical, or impractical.

use_when: External data can be matched, audited, and bounded well enough to support a limited contrast.

example_domains:
rare disease research
safety studies
policy evaluation
operations before-after studies

domain: Rare disease research

example: A single-arm study compares outcomes with a curated external natural-history cohort.

failure_modes: Selection bias dominates the apparent effect.

failure_modes: Historical measurement differs from current measurement.

failure_modes: External data are treated as if randomized.
