Public Health Needs Community Wisdom: Centering Local Knowledge to Transform Systems

Public health interventions are built on scientific evidence. Program developers rely on surveillance data, epidemiological findings, and rigorous evaluation to guide decisions that can affect millions of people. And while that rigor is invaluable, life-saving even, we see inequities persist. Gaps in healthcare access, chronic disease diagnoses, and health outcomes are laid bare in the data.

National public health systems are rightly starting to retune their attention to community engagement. Just last year the CDC and NIH, in collaboration with over 165 authoring organizations, published their updated third edition of Principles of Community Engagement positioning community engagement as a scientifically grounded, equity-driven, system-level strategy for transforming public health practice and advancing health equity.

A major advancement in the 3rd edition is the elevation of trust and trustworthiness as a core principle. This edition acknowledges that authentic engagement requires shared power, shared decision-making, shared resources, and shared accountability. The community must trust the system to uphold its end of the bargain if the system is to be effective.

Importantly and reciprocally, they elevate the importance of the system trusting in community. References to local knowledge, contextual expertise, and lived experience as evidence are woven throughout discussions of partnership, planning, research, evaluation, and implementation.

In other words, public health needs community wisdom.

Community wisdom is the lived expertise that comes from navigating systems in real time. It is the knowledge held by patients and shared with community health workers as to why a clinic feels inaccessible long before a patient misses an appointment. It is the insight of local organizers who can explain how stigma, immigration enforcement, housing instability, and trauma shape health behaviors. It goes beyond anecdote, because community wisdom is systems intelligence grounded in relation and proximity.

Yet structurally, public health is not always designed to elevate that kind of wisdom. Funding cycles prioritize rapid outputs over long-term relationship building and trustworthiness. Engagement is often treated as a step in a programming process rather than the foundation of strategy. When community input is invited after priorities are set and budgets are allocated, partnership is performative.

A Health Affairs article from 2024 details how the COVID-19 pandemic response exposed the limits of siloed, top-down public health systems and how community-based organizations (CBOs) and community health workers often filled critical gaps. These leaders stepped in to translate guidance, dispel misinformation, and coordinate resources in ways formal systems could not. They had spent years building trust and rapport with their neighbors, and their work was more effective for it.

In the same article, Chen and colleagues detail the findings of their 2023 survey on barriers to community engagement in public health systems, and they offer policy recommendations based upon these findings. Three examples of their six recommendations include: (1) requiring state and local health departments to establish formal community councils; (2) dedicating federal, state, and local funding specifically to CBOs to support their work and reduce competitive disadvantages they face; and (3) offering sustained funding for community health worker employment, career advancement, and professional organizations so as to increase diversity and community representation across the public health workforce.

These proposals, as well as the others they outline in the article, offer concrete steps public health systems can take to work with, not for, the people. Beyond platitudes about community engagement, these solutions will help systems actually engage.

Centering community wisdom requires more than listening sessions. It means working with community members before problems are defined, sharing decision-making authority, and allocating resources in ways that reflect shared ownership. It means compensating community partners equitably and supporting their leadership. And it means building accountability systems that track outcomes with communities, not just on their behalf.

When public health does this well, interventions are more durable because community buy-in comes naturally. HIV outreach strategies reflect real patterns of social networks. Chronic disease initiatives align with daily realities instead of competing with them. City greenspace designs reflect the safety needs and recreational affinities of its neighborhood. Implementation improves, and rework decreases.

Community wisdom strengthens scientific evidence. Data tells us what is happening, while community wisdom helps us understand why–and how to respond effectively. If public health systems are committed to advancing equity, the architects of the work must treat community wisdom not as supplemental, but as foundational.
