Intervention Design Pattern Library
The Pattern Genome
Every case in the Library can be read at the level of a headline — Free Hugs, a soup kitchen, a general strike. But underneath, interventions are built from smaller, reusable parts. Two cases that look nothing alike on the surface — a free-hugs campaign and a soup kitchen — often share half their underlying “genes”: trust creation, low cost, repeated ritual, dignity. The Pattern Genome is an attempt to make those shared parts visible, so the Library can be searched and compared at a much finer grain than title, country, or domain.
THE ELEVEN LAYERS
01Layer 1 — Intervention Families▾
The biggest buckets an intervention can belong to:
- Trust Building
- Mutual Aid
- Institutional Reform
- Civic Signaling
- Policy Innovation
- Environmental Restoration
- Learning Systems
- Cultural Narratives
- Economic Alternatives
- Infrastructure
- Accountability
- Care Systems
02Layer 2 — Patterns▾
Within each family, a set of recognizable patterns. Trust Building, for example, might include:
- Radical Hospitality
- Gift Economy
- Free Hugs
- Public Meals
- Neighbor Introductions
- Story Circles
03Layer 3 — Mechanisms▾
The actual engines underneath a pattern — arguably the most important table in the whole database:
- Reciprocity
- Visibility
- Reputation
- Scarcity
- Abundance
- Mimicry
- Incentives
- Feedback
- Synchronization
- Ritual
- Play
- Narrative
- Social Proof
- Identity
- Recognition
- Coordination
04Layer 4 — Tactics▾
The concrete moves an intervention actually makes:
- Blockade
- Petition
- Flash Mob
- Free Meal
- Open Letter
- Public Dashboard
- Badge
- Citizen Science
- Temporary Prototype
- Pilot
- Festival
- Gift
- Walk
- March
- Workshop
05Layer 5 — Assets▾
What the intervention actually required to run:
- Money
- Volunteers
- A church or other gathering space
- A kitchen
- AI
- A printer
- Land
- A website
- Discord / Signal
- Miro / Airtable
- A legal contract
- A mutual aid fund
06Layer 6 — Conditions▾
What had to already exist for the intervention to be possible — often the most overlooked layer:
- Existing trust
- A crisis
- Media attention
- A strong shared identity
- Shared values
- Existing institutions to work through or against
- Volunteer capacity
- A legal opportunity
- Public frustration
07Layer 7 — Power▾
Beyond Top-Down / Middle-Out / Bottom-Up, the Genome asks where an intervention’s power actually comes from:
- Legal
- Financial
- Cultural
- Moral
- Relational
- Technical
- Spiritual
- Informational
- Physical
- Institutional
08Layer 8 — Love▾
The Library’s novel contribution: instead of treating interventions as value-neutral, measure how much an intervention increases dignity, belonging, trust, agency, joy, care, beauty, and hope. Love becomes measurable, not just implied.
09Layer 9 — Developmental Stage▾
Some interventions stay seedlings. Others become institutions. Free Hugs, for example, moved through recognizable stages:
- Local community
- Annual event
- International movement
- Educational curriculum
- Cultural norm
10Layer 10 — Replication Pattern▾
How an intervention actually spreads:
- Open Source
- Franchise
- Train-the-Trainer
- Licensing
- Storytelling
- Government Adoption
- Peer-to-Peer
- Church Network
- Internet Meme
- Professional Association
- Certification
11Layer 11 — Emotional Signature▾
Most intervention frameworks focus on what people do. This Library keeps returning to a dimension almost no pattern library captures: the felt sense of the intervention. Maui’s relational car sale, the Free Hugs Campaign, Camphill, the Waste Management CEO’s Gemba walks — these all succeed partly because of the emotional field they create, not just their mechanics. That suggests emotion belongs in the schema as its own layer, not as color commentary.
| Emotional Signature | Typical Effect |
|---|---|
| Wonder | Opens imagination |
| Belonging | Deepens commitment |
| Courage | Enables action under risk |
| Care | Builds trust |
| Play | Lowers barriers |
| Sacredness | Creates stewardship |
| Justice | Mobilizes collective action |
| Curiosity | Invites participation |
| Grief | Honors loss and motivates repair |
| Pride | Sustains long-term identity |
Most design frameworks focus on what people do. Intervention Design Thinking treats what people feel while systems change as something worth mapping just as systematically.
12 — THE MASTER SCHEMA
The Master Schema
Layers 1–11 above are the analytical building blocks. In practice, every case gets reverse-engineered through a common ontology so cases can be compared apples-to-apples:
| Category | Example Fields |
|---|---|
| Identity | Name, Date, Location, Summary |
| Challenge | Problem, System, Context |
| Intention | Desired shift, Theory of Change |
| Intervention | Actions, Tactics, Sequence |
| Pattern Language | Family, Patterns, Mechanisms, Principles |
| Actors | Initiators, Stakeholders, Allies, Opponents |
| Power | Intervention Type, Power Sources, Love/Power Score, Governance |
| Resources | Time, Money, Infrastructure, Skills, Technology |
| Dynamics | Feedback Loops, Leverage Points, Emergent Behaviors |
| Outcomes | Outputs, Outcomes, Evidence, Metrics |
| Transferability | Preconditions, Adaptations, Failure Modes, Replicability |
| Learning | Lessons, Anti-patterns, Related Cases, References |
13 — WHY THIS MATTERS
Why This Matters
Once cases carry these tags, the Library stops being a list and starts being a question-answering engine. Instead of browsing, you can ask things like:
- Show me interventions that increase trust
- Show me interventions that require under $500
- Show me interventions that can be started by one person
- Show me interventions that spread virally
- Show me interventions that use ritual
- Show me interventions that reduce polarization
- Find interventions that are Bottom-Up, with Love above +8, Power between +2 and +5, requiring fewer than five volunteers, replicating within six months, operating through reciprocity
That last kind of query is the real destination: not a library you browse, but an intervention design engine you query.
A note on where this stands: the schema above is the target structure. Retrofitting all 53 published cases with full Genome tags (patterns, mechanisms, tactics, assets, conditions, power sources, developmental stage, replication pattern, emotional signature) is a larger data project, not yet done — this page documents the framework so that work has a fixed target to build toward.
