Quiz or Signal? The Rise of “Plansplaining” and What It Says About Public Participation in Planning

A quiz published by the US-based urbanism publication Planetizen asks readers to distinguish between “mansplaining” and its planning-specific cousin, “plansplaining.” While the quiz is framed as a light exercise, the term has begun to circulate in planning circles as shorthand for a familiar dynamic: the planner or planning professional who explains a scheme, policy or process in a way that assumes the listener knows less than they do, often using jargon, technical language or an authoritative tone that shuts down rather than opens up dialogue.

The quiz, written by Zachary Whalen and published on 9 October 2026, presents a series of hypothetical comments and asks whether they qualify as mansplaining or plansplaining. The scenarios are drawn from common planning interactions—public meetings, design reviews, neighbour disputes over permitted development. The piece does not claim to be a research study, but it points to a growing awareness within the profession that how planners communicate is as important as what they communicate.

Por que importa

The concept of plansplaining is not yet widely used in UK planning discourse, but the underlying dynamic is familiar to anyone who has attended a local plan consultation or a neighbourhood forum meeting in London. Residents frequently report feeling talked down to by planning officers or developers’ representatives, particularly when technical terms such as “density,” “massing,” “daylight and sunlight analysis” or “section 106 obligations” are used without explanation. The effect can be to exclude non-professionals from a process that is meant to be public.

Contexto

The quiz itself is a list of nine statements, each a single sentence. The reader is asked to judge whether the commenter is mansplaining or plansplaining. Examples include a man explaining to a woman how zoning works at a public meeting, and a planner telling a resident that their objection to a development is based on a misunderstanding of planning policy. The quiz format is deliberately playful, but the underlying point is serious: planning expertise can be used as a tool of authority rather than as a resource for shared understanding.

In London, public participation in planning is embedded in the statutory process. Boroughs must consult on local plans, neighbourhood forums can prepare neighbourhood development plans, and major applications are subject to public notice and comment periods. Yet participation rates remain low, and those who do participate are often already engaged, older, and from more affluent backgrounds. Research by the London Assembly and the Planning Inspectorate has repeatedly noted that the planning system is perceived as opaque and inaccessible, particularly by younger residents, renters, and people from ethnic minority backgrounds.

The language used in planning documents is a significant barrier. A 2023 study by the Royal Town Planning Institute found that over half of the public find planning terminology difficult to understand. Terms like “affordable housing” have specific technical meanings that differ from everyday usage, and phrases such as “sequential test,” “viability assessment,” and “heritage asset” are rarely explained in consultation materials. When planners use these terms without translation, they risk reinforcing the perception that planning is a closed profession, not a public service.

The concept of plansplaining is therefore not merely a joke. It names a real problem: the way expertise can be deployed to close down rather than open up discussion. In a profession that prides itself on technical rigour and evidence-based decision-making, there is sometimes a blind spot about how that expertise is received. A planner who genuinely believes they are being helpful by explaining a policy may unintentionally communicate that the resident’s view is less valid because it is not based on the same technical knowledge.

There is also a gender dimension. The quiz juxtaposes mansplaining and plansplaining deliberately, acknowledging that the planning profession, like many built-environment professions, remains male-dominated at senior levels. The Royal Institute of British Architects and the Royal Town Planning Institute have both published data showing that women are underrepresented in senior roles and that sexism and microaggressions are reported by women working in the field. Plansplaining may disproportionately affect women residents and women professionals alike.

For London planners and engagement teams, the quiz offers a moment for reflection. The question is not whether the term “plansplaining” will catch on in the UK, but whether the profession is willing to examine its own communication habits. Several London boroughs have already begun experimenting with more accessible consultation formats: plain English summaries, visual explainers, short videos, and drop-in sessions that do not require prior knowledge of planning law. The Greater London Authority’s “Planning for London” programme has emphasised the importance of inclusive engagement, and the London Plan itself includes policies that require boroughs to ensure that consultation is accessible to all sections of the community.

But the gap between policy and practice remains wide. A consultation that is technically compliant with the regulations may still be experienced as exclusionary if the language, tone or format discourages participation. The concept of plansplaining highlights that the problem is not just about jargon, but about the social dynamics of expertise: who gets to speak, who gets to explain, and whose knowledge is treated as valid.

The quiz format is not a research methodology, and the Planetizen piece does not claim to be more than a commentary. But it has sparked discussion in US planning circles about professional culture, and it may do the same in the UK. For readers who work in or engage with planning in London, it is worth asking whether they have ever been on the giving or receiving end of plansplaining, and what that experience tells them about the health of public participation.

The next step for interested readers is to look at their own borough’s consultation materials. Are they written in plain English? Do they explain key terms? Do they invite questions and challenge? If the answer is no, the borough may have a plansplaining problem, even if it does not use the word.
