Practice-system appendix

This page is an advanced reading appendix for people who have already used the main routes. It gathers four practice moves for noticing hidden filters, learning from uncommon practice and checking whether a room is changing the conditions that decide who gets seen, trusted, backed and heard.

Method and synthesis are different. Positive deviance is an established external approach that should be attributed carefully — Positively Devious did not invent it. This page is a public synthesis hypothesis about hidden practice, shared advantage and institutional redesign. It is not a proven model, service offer, diagnostic process, assessment or implementation guide. See what this means.

The four moves

Reveal the filter

See who gets filtered out

Name the hidden rules that decide who is recognised, trusted and resourced — the filter that removes capable people before anyone notices.

Find positive deviants

Learn from uncommon success

Find the few already achieving unusually good outcomes under the same constraints, and learn the specific, copyable behaviours behind it.

Turn practice into shared advantage

Protect it from extraction

Document the practice as a community-owned asset, shared on the community’s terms for open access — not mined as private expert insight.

Redesign the room

Change the conditions

Use what you learn to push institutions to redesign recognition, access and power — so good outcomes stop depending on luck or proximity.

Ethics gate. Where a move is deliberately devious — pre-empting how an institution would otherwise absorb a challenge — it must pass the Stage 4 ethics gate first. The aim is shared advantage and open access, never private insider advantage, hero storytelling or corporate knowledge-sharing.

Use with care

How to use the four moves without overreaching.

The practice system is a way to slow down a room and notice how opportunity is actually filtered. It is not a promise that a programme will work, a diagnostic service, a validated model, or a shortcut to judging communities.

For beginners

Learn the pattern before using the method.

If you are new to this field, start by understanding opportunity systems: how people find routes, who explains them, what hidden rules apply, and why good opportunities can still exclude people.

For organisations

Use the moves to improve the decision in front of you.

If you fund, commission, design, govern or partner around opportunity, use the moves to test meeting assumptions, route design, handoffs and accountability before backing another activity.

For everyone

Protect the boundary.

Use the moves to improve questions, decisions and conditions. Do not use them to extract stories, label people, collect disclosures, or claim proof before evidence exists.

Where this comes from

Public, documented examples of positive deviance and community leverage — the established method, and the kind of institutional change it can support. Positively Devious did not create these; we point to them to show what the method looks like in the world.

Positive deviance · public health

Child malnutrition in Vietnam

In the 1990s, Jerry and Monique Sternin with Save the Children found families whose children were well-nourished despite the same poverty, then helped neighbours copy those accessible practices — cutting malnutrition sharply and sustainably.

Positive deviance · hospital safety

Reducing hospital MRSA infections

Hospitals used positive deviance to surface frontline staff who already prevented MRSA spread, and spread those behaviours — lowering healthcare-associated MRSA infections without extra budget, including in a peer-reviewed hospital time-series study.

Community leverage · institutional change

The real Living Wage

Citizens UK organised faith groups, schools and communities to win a real Living Wage from major employers — community leverage that redesigned pay, reportedly winning over £2bn in additional wages since 2001.

These illustrate positive deviance and community leverage by others. The Positively Devious synthesis — turning such practice into protected, shared advantage and institutional redesign — is our working hypothesis, not a proven model.

Before you document positive practice: do not record people’s experiences without consent and local accountability; do not turn someone else’s survival practice into public content; do not claim a pattern is proven because one example looks promising; and use static tools only after safeguarding, consent, context and return-of-learning are clear.

Learn

I am learning the basics.

Decide

I hold an organisational decision.

Choose a route for funding, commissioning, place leadership, programme design, schools, colleges or local employers.

Open decision routes →

Question

I need better questions for a meeting.

Use decision prompts to test assumptions before money, policy, partnerships or programme design become locked in.

Open decision questions →

Tool

I want a static tool, not an intake route.

Use public checklists and templates carefully. They do not collect data, require sign-in, or open a support pathway.
