The Conditions of Coexistence

Once I arrived, the environment physically supported the quieter experience I had imagined: open outdoor space, nature, room to sit apart, and people who actually were reading, painting, sitting quietly, or participating independently.

At the same time, much of the gathering was socially active: music, dancing, conversation, introductions and networking, games, volleyball and other group activity, and people moving between one another socially.

The important observation isn't that one mode was better, that the event failed, or that the organizers misrepresented it — I'm not speculating here about what the organizers intended, their motivations, how the event is run, or how it may have evolved over time. What I became interested in was narrower than any of that: the quieter experience I'd imagined hadn't disappeared simply because a more socially active experience was happening around it. Both modes remained present in the same environment.

I didn't interview other attendees about their experience, so I can't claim there was no friction, discomfort, pressure, or disruption between the two modes. What I actually observed was narrower: neither mode appeared to completely displace the other.

I'd arrived looking for one kind of experience, encountered several different ways of participating, and noticed that one hadn't eliminated the others. That's what made me curious about what conditions in an environment allow those differences to coexist — what conditions allow one environment to support multiple, equally legitimate experiences without requiring them to converge into one.

The clearest thing I could see at the event was behavior — who danced, who read, who stayed quiet. But behavior isn't the same thing as experience. Two people doing the same thing can be having very different experiences, and people having different experiences don't always look different from the outside.

For this investigation, I'm using "experience" to mean something relational: not what an environment gives a person, and not what a person brings to an environment on their own, but what happens between the two. It's made through the encounter itself, not delivered by one side to the other. I'm adopting that definition because it's the most useful way to study what follows here — not because it settles a broader debate about what experience is, which is still genuinely open elsewhere.

Behavior still matters from here on. It's the visible trace of that relationship — just not a stand-in for the whole of it.

I found a few explanations that got partway there.

Roger Barker's behavior-setting theory, from ecological psychology, is one place to start. Its core idea is that behavior is partly organized by the recurring characteristics and expectations of a physical or social setting — different settings tend to be associated with recognizable patterns of behavior, not just whoever happens to be in them. In plainer terms, a space can behave less like a blank slate than like a script, though that's my own shorthand, not Barker's term. That establishes that settings organize behavior to some degree. It doesn't, on its own, explain why two substantially different patterns — the quieter one and the more social one — both stayed recognizable at the same event, at the same time, rather than one settling into place.

Research on restorative environments and social context — including Henk Staats and Terry Hartig's 2004 study, "Alone or with a friend: A social context for psychological restoration and environmental preferences" (Journal of Environmental Psychology, 24(2), 199–211) — looks at how a preference for solitude or company shapes what someone gets out of an environment. It offers a plausible account of why different people might approach the same setting differently: some may be looking to restore themselves through quiet or solitude, others through connecting with people. I want to be careful here — I didn't interview anyone at the event, so I can't actually assign those motives to the specific people I watched reading versus the people I watched dancing. Restoration and connection are examples of the kinds of needs people can bring into an environment, not a diagnosis of what anyone there was actually seeking. Either way, this research speaks to why people might diverge. It doesn't, on its own, explain why the setting let both needs get met side by side instead of one crowding out the other.

James J. Gibson's affordance theory offers a third account: an environment offers possibilities for action — affordances — that exist in relation to whoever is interacting with it, so the same physical environment doesn't have to function identically for everyone. A blanket on the lawn affording either reading alone or sitting near a conversation, depending on the person and the moment, is my own application of that idea, not something Gibson specifically studied. Affordance theory explains how the same environment can support genuinely different uses. It doesn't explain why those uses can go on existing side by side, without one interfering with or displacing the other.

A fourth body of research, on collective effervescence and behavioral synchrony, looks at what happens when people share rhythm, movement, attention, or emotion together — dancing, music, mutual attention. That research is about intensified connection among the people already participating in that mode; it helps explain the energy and cohesion of the dancing, the introductions, the shared conversations. It isn't a claim about what happens to everyone else nearby, and it doesn't predict that a reader sitting at the edge of that energy should eventually be pulled into it. Nothing here tested whether synchrony radiates outward that way. What I can actually say is narrower: the readers stayed readers. Nothing pulled them in, and nothing pushed them out.

Between all four, most of the divergence is well accounted for. None of them explain why it held.

A City Sidewalk

The writer and urbanist Jane Jacobs spent years watching city sidewalks do something similar, at a much larger scale, and documented both when it worked and when it didn't, in The Death and Life of Great American Cities.

Her successful case: dense, mixed-use city blocks, home to people heading to work, to a shop, to their own front stoop — all moving through the same sidewalk for reasons that had nothing to do with each other. Nobody was there because of anybody else. Cycling through together anyway, they produced what she called a sidewalk ballet — a shared order that nobody was directing.

Her failed case sat a few blocks away, in postwar public housing towers surrounded by open plazas anyone was technically free to use however they liked. The plazas stayed empty. Without people passing through for their own unrelated reasons, there was nothing to sustain shared use. The empty plazas didn't stay peaceful — they became unsafe.

Permission was equally present in both cases. What I took from Jacobs's comparison was the possible importance of people arriving for genuinely different, independent reasons — that's my read of what distinguished the two cases, not a condition Jacobs herself set out to establish.

An Open-Plan Office

A more recent, better-measured case comes from ordinary office buildings. Ethan Bernstein and Stephen Turban's 2018 field studies, published as "The Impact of the 'Open' Workspace on Human Collaboration," tracked real employees through a transition to more open office layouts and found close to the opposite of what the change was meant to produce: face-to-face interaction fell by roughly 70 percent, while electronic communication rose to fill the gap. Removing the walls between desks didn't blend focused work and spontaneous collaboration the way the redesign intended. People didn't blend the two modes. They withdrew from both.

This is the case that looks the most like the event and behaves the most differently from it. Both are open, unzoned, self-signaled spaces meant to hold more than one mode at once. But a phone ringing at an empty desk reaches every desk, the way a dancer's noise never had to reach a reader with enough lawn between them. There was nowhere for the difference to go that didn't cost the other mode something. It broke. I'm using Bernstein and Turban's finding as a contrasting case, the same way I'm using the others here — they weren't testing anything like the coexistence question this investigation asks.

A Public Library

A public library is a useful design contrast here, though I'm using it as one example of how a library can be designed, not a claim about how every library works. Many public libraries hold silent study, loud children's programming, computer use, and casual browsing in the same building, at the same time, without collapse. Professional guidance from library organizations — including IFLA's library building guidelines and the American Library Association's YALSA Teen Space Guidelines — points to why: deliberate spatial and acoustic differentiation, not an absence of structure. Distinct rooms, different acoustic treatment, different furniture, often a person on staff actively managing the boundary between them.

What that suggests, as a design principle, is that a space doesn't have to erase the difference between quiet and loud activity to hold both. It can give each one its own place to happen without the other reaching it. Not every library draws that boundary in the same place, or ranks its zones the same way — the useful idea is the differentiation itself, not a specific hierarchy every library shares.

Two guesses came first, and both had to be abandoned once they met more than one case.

The first was permission — that a loosely defined setting is what makes room for divergence in the first place. It didn't survive the library, the least loosely defined of the three environments and the one that worked best. Permission turned out to matter only in the most basic way — nothing coexists in a space that forbids it outright — and it explained none of the actual difference between the cases that worked and the one that didn't.

The second guess, drawn from the office, was that no mode could be allowed to outrank another. The library complicates that one too: it differentiates its zones deliberately rather than treating every activity the same, and it still works.

Across the cases I examined — a city sidewalk, an office floor, and a library — two features kept resurfacing, revised twice before I was willing to put them this plainly: people arriving for genuinely different, independent purposes, and the environment providing enough separation or capacity for different modes to unfold without materially interfering with one another. These are candidate conditions this concept study suggests, not conditions I've demonstrated to be necessary or sufficient for coexistence — a possibility worth carrying forward, not a settled answer.

None of this is a validated framework — it's a concept study built from one lived observation and three contrasting cases, not a controlled study. But it does translate into a small set of questions that feel useful for anyone designing an environment, experience, service, or gathering meant to hold more than one person's version of it at once:

• Can people arrive for genuinely different, independent reasons — not just be assigned to different roles within the same shared purpose?
• Can those different modes unfold without materially interfering with one another — through separation, capacity, zoning, or some other means?

Those two questions come directly from the two candidate conditions above. The original event raised another question the comparison didn't test:

• Can people understand the range of experiences an environment supports before they enter it?

I'm keeping that as an open implication rather than a third condition.

I'm calling this a provisional lens deliberately. It's a way of asking better questions about coexistence, not a checklist that guarantees it.

• Whether the two candidate conditions are actually independent of each other, or whether one only works because the other is already in place — every case here had both present or both absent, and none of them separate the two.
• What produces the shared, relaxed undertone that seemed to run underneath both modes at the event itself, even though nothing here tested for it directly.
• Where a person's need for rest or for connection actually comes from, before they ever arrive — every account here treats that difference as a given, not as something to explain.
• Whether any of this holds outside a physical room at all — inside a product, a conversation, or an interaction with a piece of technology built to hold more than one person's needs at once.

None of the cases here can tell me whether the two candidate conditions work independently or only together. That's where this concept study stops.

What it leaves behind is a clearer way of thinking about coexistence: not as getting everyone to participate in the same way, but as creating enough room for different ways of participating to remain legitimate at the same time.
