Who to involve — and who we leave out unintentionally

01 Why is it a decisive question who we involve?

The legitimacy of participation stands or falls on how far the group involved represents those affected. If a local government renovates a public space but only the most active, loudest residents of the neighbourhood speak up, the outcome will reflect their needs — not necessarily those of the park's actual users. The needs of mothers with young children, of older people, of the young, or indeed of those who come from elsewhere may remain invisible.

The question of involvement is therefore not a technical detail but the foundation of the process's validity. A "residents' opinion" based on a distorted sample can be more misleading than if no one had been asked at all — because the distortion is authenticated by the appearance of participation.

02 The trap of self-selection

The most common mistake is a process built on self-selection. When anyone who wants to can come — whether it is an open forum or an online questionnaire — a very particular circle typically shows up: those who have the time, the confidence, the digital access, and who are already strongly affected by or interested in the topic. This circle almost never mirrors the whole community.

Self-selection is not deliberate exclusion, yet it regularly distorts. It over-represents middle-aged, educated residents versed in public affairs, and under-represents the young, the old, those on lower incomes, minorities and all those for whom daily subsistence leaves no energy for public life. It is precisely those whose voice is most missing who are left out.

03 Two paths: open or representative?

Involvement has fundamentally two logics, and it is important to choose consciously between them.

• Open participation: anyone can join in. Its advantage is broad legitimacy and a diversity of ideas; its disadvantage is that it is self-selecting and therefore distorts. It is excellent for gathering ideas and community-building, but not suitable for representing "the community's opinion".
• Representative participation: participants are selected so that the group mirrors the population. Its advantage is that it gives a credible, balanced picture; its price is more complex organisation and a smaller number of people.

The two approaches do not exclude each other. Many good processes combine them: they gather ideas and local knowledge in an open phase, then entrust the deliberation and the formulation of recommendations to a representative body.

04 Stratified sampling as a solution

The most reliable tool of representativeness is stratified random sampling. Its essence is that participants are selected by draw, but in such a way that the composition of the group mirrors the whole population according to certain criteria — age, sex, educational attainment, place of residence and often other characteristics.

In practice this typically works as follows: first several thousand randomly selected residents receive an invitation, then the final participants are drawn from among those who apply — thereby ensuring that the group is balanced according to the important criteria. This both avoids the distortion of self-selection and ensures that those usually left out also get in. A separate article deals with the details of the method.

05 Conscious work against quiet omission

Representative selection is in itself necessary but not sufficient. Someone who gets into the room is not yet certain to speak up. The barriers of access — a bad time, an inaccessible venue, the lack of childcare, language difficulties or simply a lack of self-confidence — can quietly filter out some of the participants.

That is why a good process works actively on involvability: it chooses convenient times and venues, provides childcare and reimbursement, uses accessible and understandable materials, and applies moderation that gives space to the quieter ones too. The goal is for participation to be open to everyone not just formally but actually.

06 The two levels together: open and representative

In practice the best processes do not choose definitively between open and representative logic but consciously combine them. A typical structure looks like this: at the start an open phase gathers ideas, local knowledge and the problems that arise — anyone interested in the matter can contribute here. This phase provides rich raw material and generates attention and commitment broadly. Then a representative body selected by draw — for example a community meeting — takes the deliberation in hand: from the collected material, with balanced information, it works out well-founded recommendations.

This way the strength of both approaches prevails: the open phase gives diversity and legitimacy, the representative phase gives credibility and depth. The key is that it be clear what each phase is for — open idea-gathering must not be confused with the representative measurement of "the community's opinion", because the two do different things.

07 Example: a decision affecting a public space

Let us look at a concrete situation. A local government wants to renovate an ageing playground. If it announces the consultation only in the local residents' online group, in all likelihood the most active, digitally versed, typically younger parents will speak up — the older people who use the benches, or the teenagers for whom the space is their meeting place, are left out. The outcome would reflect the needs of a narrow circle.

A conscious process, by contrast, actively seeks out the various user groups: it goes out to the space at different times of day, addresses older people and the young, ensures that the questionnaire is also available on paper, and entrusts the deliberation to a representative sample. The same playground, with a radically different — and far fairer — result.

08 A few questions for planning

Before a process starts, it is worth running through a few questions. Who is actually affected by this decision — and which of them tend to be left out? Does the chosen method reach them too, or does it reinforce the usual distortion? What barriers might keep participants away, and what do we do against them? Do we want a representative picture of the community, or rather many ideas — and does the chosen tool fit this? The honest answers to these questions decide whether the process really gives voice to the community, or only to a slice of it.

09 Summary

The key question of involvement is not how many take part, but who — and who is left out unnoticed. Processes built on self-selection regularly amplify the loudest, while leaving out the usually quiet groups. Stratified random sampling and conscious removal of barriers together make it possible for participation to genuinely mirror the community. The next article examines what happens when these guarantees are missing — that is, when participation does not work.
