Marketplace reasoning-dialectical
Synthesize competing positions through structured thesis-antithesis-synthesis process. Use when stakeholders disagree, trade-offs exist, or multiple valid perspectives need integration. Produces integrated positions with acknowledged trade-offs.

skills/bellabe/reasoning-dialectical/SKILL.mdDialectical Reasoning
Synthesize opposing views into higher-order resolution. The logic of productive disagreement.
Type Signature
Dialectical : Thesis → Antithesis → Synthesis Where: Thesis : Position × Evidence × Stakeholder → ArgumentA Antithesis : ArgumentA → CounterPosition × Evidence × Stakeholder → ArgumentB Synthesis : (ArgumentA, ArgumentB) → IntegratedPosition × Tradeoffs
When to Use
Use dialectical when:
- Stakeholders hold opposing valid positions
- Trade-offs need explicit analysis
- Strategic tension requires resolution
- Multiple perspectives each have merit
- "On one hand... on the other" situations
Don't use when:
- Cause-effect chain needed → Use Causal
- Explaining observation → Use Abductive
- Evaluating past decisions → Use Counterfactual
Core Principles
Charitable Interpretation
Each position must be represented at its strongest:
- Steel-man, don't straw-man
- Assume good faith and valid reasoning
- Identify the kernel of truth in each view
Genuine Synthesis
Synthesis is NOT:
- Compromise (splitting the difference)
- Victory (one side wins)
- Avoidance (postpone decision)
Synthesis IS:
- Integration at higher level of abstraction
- Resolution that addresses underlying concerns
- New position that transcends original framing
Three-Stage Process
Stage 1: Thesis
Purpose: Articulate first position at maximum strength.
Components:
thesis: position: statement: "Core claim being made" underlying_concern: "What this position is really about" stakeholder: who: "Person/team holding this view" role: "Their organizational function" incentives: "What they optimize for" evidence: supporting: - claim: "Evidence point" source: "Where this comes from" strength: 0.0-1.0 empirical: [DataPoint] logical: [Argument] implications: if_adopted: "What happens if we go this way" risks: [Risk] benefits: [Benefit]
Example:
thesis: position: statement: "We should prioritize enterprise features over SMB growth" underlying_concern: "Revenue concentration and deal size efficiency" stakeholder: who: "Sales leadership" role: "Revenue generation" incentives: "ARR, deal size, quota attainment" evidence: supporting: - claim: "Enterprise deals average $400K vs SMB $5K" source: "Q3 sales data" strength: 0.95 - claim: "Sales cost per $ revenue 5x lower for enterprise" source: "CAC analysis" strength: 0.85 empirical: - "3 enterprise deals = entire SMB revenue" - "Enterprise churn 3% vs SMB 8%" implications: if_adopted: "Focus engineering on enterprise features, reduce SMB investment" risks: - "Lose SMB market to competitors" - "Revenue concentration risk" benefits: - "Higher margins" - "Larger average deal"
Stage 2: Antithesis
Purpose: Articulate counter-position at maximum strength.
Process:
- Identify what thesis misses or undervalues
- Find stakeholder with opposing view
- Build strongest case for alternative
- Identify where thesis assumptions break
Components:
antithesis: position: statement: "Counter claim" underlying_concern: "What this position is really about" stakeholder: who: "Person/team holding this view" role: "Their organizational function" incentives: "What they optimize for" critique_of_thesis: - assumption_challenged: "Thesis assumes X" counter_evidence: "But actually Y" - risk_identified: "Thesis ignores Z" evidence: supporting: [EvidencePoint] empirical: [DataPoint] logical: [Argument] implications: if_adopted: "What happens if we go this way" risks: [Risk] benefits: [Benefit]
Example:
antithesis: position: statement: "SMB volume creates the foundation for sustainable growth" underlying_concern: "Market presence, product iteration, and risk distribution" stakeholder: who: "Product leadership" role: "Product-market fit and growth" incentives: "Usage, retention, feature validation" critique_of_thesis: - assumption_challenged: "Enterprise features drive growth" counter_evidence: "SMB usage generates product insights 10x faster" - assumption_challenged: "Revenue concentration is acceptable" counter_evidence: "Losing 1 enterprise deal = losing 80 SMB accounts" - risk_identified: "Enterprise sales cycle is 9 months" evidence: supporting: - claim: "SMB accounts generate 80% of feature requests" source: "Product feedback analysis" strength: 0.90 - claim: "SMB provides faster iteration cycles" source: "Release metrics" strength: 0.85 empirical: - "SMB churn prediction accuracy 95% vs enterprise 60%" - "Product improvements from SMB feedback shipped in 2 weeks" implications: if_adopted: "Maintain SMB investment, use as product lab" risks: - "Slower revenue growth short-term" - "Lower margin overall" benefits: - "Diversified revenue base" - "Faster product iteration" - "Lower concentration risk"
Stage 3: Synthesis
Purpose: Integrate positions at higher level, resolving underlying tensions.
Synthesis Approaches:
| Approach | When to Use | Example |
|---|---|---|
| Integration | Both positions address valid concerns | "Enterprise revenue + SMB as product lab" |
| Sequencing | Temporal resolution possible | "SMB first for PMF, then enterprise scale" |
| Segmentation | Different contexts warrant different approaches | "SMB for product X, Enterprise for product Y" |
| Reframing | Original dichotomy was false | "The real question isn't SMB vs Enterprise, it's time-to-value" |
| Transcendence | Higher goal subsumes both | "Optimize for sustainable unit economics regardless of segment" |
Synthesis Components:
synthesis: integrated_position: statement: "What we will actually do" framing: "How this resolves the tension" how_thesis_is_addressed: concern_validated: "What's true about thesis" how_incorporated: "How we address that concern" how_antithesis_is_addressed: concern_validated: "What's true about antithesis" how_incorporated: "How we address that concern" trade_offs_acknowledged: - trade_off: "What we're giving up" mitigation: "How we reduce impact" accepted_by: "Stakeholder who accepts this" resolution_type: integration | sequencing | segmentation | reframing | transcendence implementation: actions: [Action] metrics: [Metric] # How we know it's working review_date: date # When we reassess
Example:
synthesis: integrated_position: statement: "SMB as rapid learning engine, enterprise as revenue engine, with explicit feature graduation path" framing: "Not SMB vs Enterprise, but learning velocity vs revenue efficiency with a bridge between them" how_thesis_is_addressed: concern_validated: "Enterprise deals are more efficient per dollar" how_incorporated: "Maintain enterprise sales motion, prioritize enterprise features that have been validated through SMB" how_antithesis_is_addressed: concern_validated: "SMB generates faster product learning" how_incorporated: "Protect SMB investment as product lab, use SMB metrics to prioritize enterprise features" trade_offs_acknowledged: - trade_off: "Some enterprise-only features will ship slower" mitigation: "Identify 'must have' enterprise features, fast-track those" accepted_by: "Sales leadership (with fast-track list)" - trade_off: "Some SMB features won't graduate to enterprise" mitigation: "Clear graduation criteria defined upfront" accepted_by: "Product leadership (with criteria agreement)" resolution_type: integration implementation: actions: - "Define feature graduation criteria (Product + Sales)" - "Create SMB → Enterprise feature pipeline" - "Allocate 60% engineering to graduated features, 40% to SMB lab" metrics: - "SMB feature graduation rate (target: 3/month)" - "Enterprise close rate on graduated features (target: +20%)" - "Combined revenue growth (target: 30% QoQ)" review_date: "End of Q2"
Quality Gates
| Gate | Requirement | Failure Action |
|---|---|---|
| Thesis strength | Steel-manned, evidence-backed | Strengthen before proceeding |
| Antithesis genuine | Not straw-man, different stakeholder | Find genuine opposition |
| Synthesis integrative | Not compromise or victory | Reframe until true synthesis |
| Trade-offs explicit | All parties acknowledge costs | Surface hidden disagreements |
| Actionable | Concrete next steps | Add implementation detail |
Stakeholder Agreement Protocol
Synthesis isn't complete until affected stakeholders acknowledge:
- Their concern was understood (thesis/antithesis accurately represented)
- The synthesis addresses their core interest (not just their stated position)
- They accept the trade-offs (explicitly, not assumed)
stakeholder_acknowledgment: thesis_stakeholder: name: "Sales leadership" concern_understood: true synthesis_addresses_concern: true accepts_trade_offs: true conditions: "Fast-track list for critical enterprise features" antithesis_stakeholder: name: "Product leadership" concern_understood: true synthesis_addresses_concern: true accepts_trade_offs: true conditions: "Clear graduation criteria before implementation"
Common Failure Modes
| Failure | Symptom | Fix |
|---|---|---|
| False dichotomy | Positions aren't truly opposed | Reframe the actual tension |
| Straw-man | Weak representation of one side | Involve actual stakeholder |
| Mushy middle | Synthesis is just "do both" | Force resource allocation |
| Unacknowledged loss | Trade-offs hidden | Surface what's being given up |
| No implementation | Synthesis is abstract | Add concrete actions |

Example Execution
Context: "Engineering wants to rebuild core platform (6 months). Sales wants new features for Q2 deals."
Stage 1 - Thesis (Engineering):
Position: "Technical debt is blocking velocity. Rebuild now or pay 10x later." Evidence: - Deploy time increased 300% YoY - 40% of sprint spent on workarounds - 3 critical bugs from architecture issues Underlying concern: Sustainable development velocity
Stage 2 - Antithesis (Sales):
Position: "We have $2M in pipeline dependent on Q2 features. Delay = lose deals." Evidence: - 5 enterprise deals waiting on specific features - Competitor launching similar features in March - Q2 quota at risk without new capabilities Underlying concern: Revenue target attainment
Stage 3 - Synthesis:
Integrated position: "Strangler fig pattern - rebuild incrementally while delivering high-priority features" How thesis addressed: Platform rebuild happens, but in modules alongside features How antithesis addressed: Q2 features delivered, no delay Trade-offs: - Rebuild takes 9 months instead of 6 (Engineering accepts) - Only top 3 features in Q2, not all 5 (Sales accepts with prioritization input) Resolution type: Integration via sequencing Implementation: - Week 1: Joint prioritization session (top 3 features + first rebuild module) - Q2: Deliver features on new modules where possible - Q3-Q4: Complete rebuild with feature delivery continuing
