The Tribe Cheatsheet

I. How to Use This Page

The material draws from Elinor Ostrom’s commons-governance research, the synchrony and social-bonding literature, the motivational-interviewing approach to supporting change, and the broader frameworks developed across the Unity section.

Most readers will want to scan for something relevant to their current situation rather than reading the page linearly. The Quick Reference Index supports this. From there, jump to the relevant section for more detail.

Unification covers the synchronising practices and the Game B design. Selfishly Altruistic covers the cooperation that sustains community. Tribes vs Cults covers the protective distinction. 

A note on scope, carried from the Unity overview: this section treats community as a tool for collective change rather than as an individual need for social safety. The individual relational need is covered in Connection. This page is about building and joining functioning collectives, not about meeting your personal need for friends.

III. Ostrom’s Commons Design Principles

Elinor Ostrom won the 2009 Nobel Prize in Economics for documenting how real communities successfully govern shared resources (fisheries, forests, irrigation systems, grazing land) without either privatising them or handing them to a central authority. Her eight design principles are among the more empirically grounded findings on how durable, self-governing collectives actually work. They apply far beyond literal commons to any group managing something shared.

1. Clearly defined boundaries: The group knows who is a member and who is not, and what the shared resource or purpose actually is. Vague membership and vague purpose both corrode community. This is not about exclusion for its own sake; it is about clarity. People need to know whether they are in or out and what they are part of.
2. Rules matched to local conditions: The rules fit the specific community and its actual situation, rather than being imported wholesale from elsewhere. What works for one community may not work for another. The rules should be appropriate to your group’s real circumstances, not borrowed uncritically.
3. Participation in making the rules: The people affected by the rules participate in shaping them. Rules imposed from above are resented and evaded; rules that members helped create are followed because they are genuinely the members’ own. This is one of the clearest dividing lines between a healthy community and coercive control.
4. Monitoring: The community can see whether members are keeping the agreements, and the monitoring is done by or accountable to the members themselves. Trust works better when it is verifiable. This is not surveillance; it is the transparency that lets a group hold itself to its commitments.
5. Graduated sanctions: Violations are met with proportionate responses that escalate only as needed, starting gently. A first lapse gets a light touch; repeated or serious violations get firmer responses. The graduated approach maintains cooperation without either letting violations slide (which destroys the commons) or coming down so hard on first offences that it fractures the community.
6. Conflict-resolution mechanisms: The community has accessible, low-cost ways to resolve disputes. Conflict is inevitable in any group; what distinguishes durable communities is having agreed ways to work through it rather than letting it fester or explode. This connects to the tit-for-tat forgiveness covered in Selfishly Altruistic: communities need a way back to cooperation after conflict.
7. Recognition of the right to organise: The wider environment (and any larger authority) recognises the community’s right to govern itself. A community constantly fighting for the basic right to exist and self-organise spends its energy on survival rather than function.
8. Nested enterprises: For larger systems, governance is organised in nested layers, with smaller units inside larger ones. This connects directly to the Dunbar layers below: a large community functions by being composed of smaller functioning units rather than trying to operate as one undifferentiated mass.

When joining a community, notice which principles it embodies and which it lacks; the gaps predict where it will struggle. When building one, treat these as a design checklist. The principles are not a guarantee (communities fail for many reasons) but they improve the odds, and they are based on the study of communities that actually succeeded over long periods.

IV. The Synchronising Practices

The bonding technologies covered in depth in Unification, here as a practical quick reference. These are the most reliable ways to bond a group, and most require no special resources.

Music: One of the oldest and most powerful bonding technologies. Tied into purpose, movement, learning, and the social.

• Pattern recognition that the brain finds inherently rewarding
• A unifying language that represents emotional frequencies more directly than words
• Synching with others by inhibiting the anxious thought of self and contributing to something outside yourself
• Flow, both individual and collective

Singing together, making music together, or even just listening together, all bond a group. The choir effect (synchronised heart rate variability among singers) is legit.

• Movement and dance: Synchronised movement triggers the endorphin and bonding effects most strongly. Group dance, group exercise, martial arts, any coordinated physical activity. The body coordinating with other bodies produces the muscular bonding that forges groups.
• Shared meals: Eating together is among the oldest community rituals. The shared meal creates a regular occasion to gather; the act of sharing food triggers reciprocity, and the relaxed setting supports the conversation that builds relationships. The potluck (despite the 99c-chips risk) is a genuine community technology.
• Shared challenge: Facing difficulty together bonds people. Physical challenge, intellectual challenge, a shared project with real stakes. The bond formed through mutual difficulty is more durable than the bond formed through mutual comfort.
• Ritual and regularity: Recurring gatherings at predictable times build community through sheer repetition. The weekly meeting, the seasonal celebration, the regular practice. Ritual provides the rhythm that holds a community together across time.

V. Finding and Joining Healthy Community

Practical guidance for the person looking to join a community rather than build one.

• Start with synchronising activities: Choirs, dance classes, group fitness, martial arts, drumming circles, team sports. These lower the barrier to entry because the synchrony does the bonding work; you do not have to be good at conversation to belong, you just have to show up and participate.
• Look for shared practice, not just shared identity: Communities organised around doing something together (a craft, a sport, a discipline, a cause) tend to be healthier and more durable than communities organised purely around a shared identity or belief. The shared practice gives ongoing reason to gather and a basis for a relationship beyond agreement.
• Show up repeatedly: Community is built through repeated presence. The first few times feel awkward; this is normal and passes. Most people quit before the awkwardness fades. The bond forms through repetition, so the single most useful thing you can do is keep showing up.
• Contribute: The fastest route into a community is to be useful to it. Bring something, help with something, take on a task. Contribution both bonds you to the group and gives you a role, which is more comfortable than being a passive newcomer.
• Run the health check: Before investing heavily in any group, run the Tribes vs Cults Quick Check below. Notice whether the group increases or decreases your autonomy and your freedom to leave.

VI. Building Community From Scratch

Practical guidance for the person creating a community where none exists.

• Start small and regular: A small group meeting regularly beats a large group meeting sporadically. Begin with a handful of people and a predictable rhythm. The regularity matters more than the size at the start.
• Organise around a real shared purpose or practice: Give the group an actual reason to exist beyond “we should have community.” A shared activity, a shared project, a shared goal. The purpose provides the gravity that holds people together.
• Use the synchronising practices: Build in music, movement, shared meals, or shared challenge. Do not just talk; do something together that triggers the bonding mechanisms.
• Apply Ostrom’s principles: Clear boundaries, member participation in the rules, accessible conflict resolution, graduated responses to problems. Treat the principles as a design checklist from the start rather than trying to retrofit them after problems emerge.
• Respect the Dunbar layers: Build for the scale you are actually at. Do not try to run a 100-person community with the informal structure that works for 10. As the group grows, develop the nested structure that the larger scale requires.
• Keep it open: Make the workings transparent, share how it functions, resist the drift toward gatekeeping and charismatic centralisation. This is both healthier and a protection against the cult dynamic.
• Tend it patiently: Community is built over years. Show up, hold the difficulties, let it grow slowly. There is no shortcut.

VII. Helping Others Through Change

A specific skill worth its own treatment, because building and sustaining community often involves supporting people through change, and the instinct to push people toward change usually backfires.

People resist being changed by others and are far more moved by their own reasons than by anyone else’s. Direct persuasion (telling people what they should do, marshalling arguments, applying pressure) tends to produce resistance rather than change, because it triggers the autonomy-defending response. The more you push, the more the other person defends their current position.

Motivational Interviewing: An evidence-based approach developed by William Miller and Stephen Rollnick, originally for addiction counselling and now applied broadly. The approach helps people find their own motivation for change rather than imposing it.

• Express empathy: Understand the person’s perspective genuinely before doing anything else. People who feel understood become open; people who feel judged become defensive.
• Develop discrepancy: Help the person notice the gap between their current behaviour and their own deeper goals and values. The motivation comes from their values, not yours.
• Roll with resistance: Do not fight resistance directly; that strengthens it. When the person pushes back, acknowledge it and explore it rather than countering it.
• Support self-efficacy: Help the person believe change is possible for them. Hopelessness prevents change; a sense of capability enables it.

The deeper resources on Motivational Interviewing are worth consulting directly for anyone in a helping, coaching, or leadership role:

• The Australian Government health-publications guide to motivational interviewing
• The NIDDK (National Institute of Diabetes and Digestive and Kidney Diseases) practitioner guidance on motivational-interviewing dos and don’ts
• The BPAC NZ (Best Practice Advocacy Centre) motivational-interviewing resource
• The Health Navigator NZ video series on motivational interviewing for clinicians

Motivational Interviewing works precisely because it respects autonomy. Rather than overriding the person’s self-direction (which triggers resistance and, taken far enough, becomes the coercive dynamic of Tribes vs Cults), it supports the person in finding their own reasons. This is the healthy way to support change in a community, and it maps directly onto the manual’s core autonomy commitment.

VIII. The Tribes vs Cults Quick Check

The single-test version of the Tribes vs Cults page, for quick application to any group.

Does this group increase or decrease my capacity to think for myself and to leave?

Quick warning signs (any of these warrants closer attention):

• Questioning the leader or doctrine is discouraged or punished
• Leaving would be catastrophically costly (loss of all relationships, identity, livelihood)
• The group controls your information, time, relationships, or finances increasingly
• You are told to distrust your own perception when it conflicts with the group line
• The world is divided sharply into the pure in-group and the corrupt outside
• Your outside relationships are attenuating as the group demands more
• A charismatic leader is beyond accountability, and the group serves them

Quick health signs (these characterise a synergistic community):

• Questions and disagreement are welcomed
• Leaving is genuinely possible, and departed members are treated with goodwill
• You are becoming more capable and more independent, not less
• Your own perception is treated as valid
• The group holds its identity without demonising outsiders
• Your outside life is intact or enriched
• Leaders are accountable and serve the members

When in doubt, watch the trajectory over time: are you becoming freer and more capable, or less?

IX. The Dunbar Layers

Practical scale guidance from Robin Dunbar’s research on the cognitive limits of social relationships. Communities that respect these layers function; communities that ignore them struggle.

The practical implications:

• Intimate groups (5-15) work through direct personal relationships and informal coordination
• Mid-size communities (50-150) need some structure but can still run on personal relationships and shared norms
• Beyond ~150, the informal trust-based coordination breaks down and you need explicit structure, roles, and the nested organisation Ostrom’s eighth principle describes
• A large community functions best as a set of nested smaller groups rather than one undifferentiated mass

When a group struggles, a scale mismatch is often the cause: too large for its informal structure, or too small to achieve its purpose. Matching structure to scale is one of the more useful practical moves available.
