This piece is a thought experiment conducted through simulated interviews. The two interviewees are fictional characters synthesized from environmental psychology, behavioral science, and urban studies—representing no real individuals or viewpoints.
In May, I explored caves, rode motorcycles, and met strangers in Vang Vieng. By June, back in Shenzhen, I often did not come alive until after dark, relied on short videos to lull myself to sleep at two or three in the morning, and lacked the energy even to step outside during the day.
At first glance, this contrast seems to reveal a personality: the former as bold, open, and vibrant; the latter as procrastinating, withdrawn, and lacking discipline.
Yet it’s the same person—less than a month apart.
In the past, I’d attribute this shift to “instability.” Now I wonder: Is the stable self we imagine merely a systematic underestimation of environmental influence?
Personality May Not Be as Portable as We Think
Me: Why do I feel like a different person in different cities?
Environmental Psychologist: Behavior isn’t a direct output of personality. Let’s reconstruct those two mornings.
In Vang Vieng, companions awaited downstairs, motorcycles needed to be ready before the heat rose, and mountains were visible in the distance. After waking, the next step was almost written in the streets. In Shenzhen, the rented apartment had no one waiting, curtains blocked the morning light, phones and beds were within reach, and work had to be self-defined. These two settings activated different parts of the same person.
This doesn’t prove environment explains everything. The novelty of travel, sleep debt, post-return disorientation, or even a temporary low mood could also play a role. Environmental psychology reminds you: when comparing behaviors, don’t erase the interface that generated them. It can’t diagnose causes through a single month’s journal.
Urban Researcher: Cities do not just accommodate behavior; they also price it. Whether walking is comfortable, chance encounters are possible, a person sitting alone in public will be moved along, and safe places exist at night without requiring a purchase—all of these conditions shape who it is easier to become each day.
Some cities allow relationships to unfold naturally; others require you to schedule, commute, consume, and explain first. The latter isn’t devoid of social connection—it’s just that each connection demands a separate activation. When these activation costs accumulate, they can be misread as “I’ve become more introverted.”
“The Real Me” Might Be a Misleading Question
Me: So which one is the real me—the explorer or the downshifted self?
Environmental Psychologist: Both are authentic reactions, but neither defines the whole person.
We tend to infer essence from behavior: not going out today means I’m lazy; being able to talk deeply with strangers in a bar means I’m extroverted. Yet the same person draws on different behavioral strategies depending on relationships, lighting, sleep, temperature, and feedback loops.
Personality isn’t a software package that runs identically in any setting. It’s more like a set of conditional branches. Instead of asking “Who am I?”, I’d ask: Under what conditions do specific parts of me emerge?
Me: Could this become a way of avoiding responsibility? Blaming everything on the environment?
Environmental Psychologist: Only when you conflate explanation and responsibility does this happen.
Environmental explanations describe how behavior occurs—they don’t decide whether you should change. In fact, acknowledging environmental influence shifts responsibility from shame to design. Proving you can win through willpower in the worst conditions matters little; creating conditions that increase the likelihood of meaningful behavior is what truly addresses the issue.
Responsibility doesn’t require daily self-judgment. It can also mean modifying the conditions that run before outcomes.
Why Travel Can Temporarily Heal Some Issues
In unfamiliar cities, I’d walk actively, wake early to observe alms, and pay attention to street vendors and people’s expressions. Returning to familiar spaces, perception would gradually fade.
Urban Researcher: Unfamiliar environments often temporarily disable old routines. Routes, food, and etiquette need reconfirmation, and attention returns to the present moment. The “living” you experience comes partly from novelty and partly from action and feedback reconnecting. Some people feel overwhelmed or withdraw in unfamiliar settings—a reaction that isn’t universal.
In highly familiar environments, many life details compress into predictions. Fewer distinguishable moments in memory can make time feel as if it didn’t happen. This describes a common experience when reviewing a period; immersion, flow, or pain might still redirect the present moment in entirely different ways.
But travel isn’t a permanent solution. After living long enough, new cities develop default scripts. Vientiane’s water festival initially lit you up with collective emotion, but after the festival ended, the gap pulled you back empty. After a month, drinking and chatting became habitual rather than a choice. Environmental influence isn’t just geographic—it’s whether a behavior still requires active engagement.
The Most Dangerous Environment Has No Obvious Hostility
True danger doesn’t always feel painful. It might be comfortable, quiet, and non-intrusive, yet slowly erode your ability to initiate.
Phones don’t demand I scroll until 3 a.m.; rented apartments don’t forbid me from leaving. They simply make immediate relief very close while delaying physical activity, authentic relationships, and long-term projects. Each choice feels minor, but after a month, it feels as though someone else has written my life.
Me: Why do people always interpret this outcome as a willpower problem?
Environmental Psychologist: Willpower offers a simple, morally intuitive explanation. It reduces complex systems to “you should work harder,” and protects the environment designers: platforms, organizations, and spaces don’t need to be responsible for the tendencies they continuously create.
But there’s also a trap. Some people switch cities at the first sign of discomfort, treating environment as a universal variable. New settings can interrupt old cycles but don’t build new capabilities. Without stable relationships, body rhythms, or external commitments, moving cities often resets rather than repairs.
Cities Are Vast—What Matters Is the Ten Meters You Walk in a Day
Attributing differences to “Vang Vieng,” “Vientiane,” or “Shenzhen” is still too broad. Within Shenzhen itself, living in a room with curtains that stay closed, walking daily past parks to shared offices, or knowing a few shops in a city neighborhood can create vastly different lives. City names don’t explain the path you actually walk.
Urban Researcher: Urban researchers are wary of assigning personalities to cities. Shenzhen does not inherently make people sink, and Laos is not inherently relaxed. What matters is a set of micro-infrastructures: how far the door is from the street, whether there is anywhere to pause along the way, whether public space requires spending money, whether anyone recognizes you, and whether your workplace makes your rhythm visible.
Vientiane’s water festival especially illustrates this. The city’s architecture didn’t change overnight, but collective permission did: strangers could splash, approach, and laugh together, turning streets from passageways into shared spaces. After the festival, permission withdrew, and the same street felt cold again. What affected me wasn’t “Vientiane’s personality”—it was the temporary rules that changed how close people could be.
Don’t Move—Change the Path You Take Out
If environment truly influenced my downward shift in June, the most useful test isn’t moving countries. I could run a smaller comparison in Shenzhen.
For the first week, I would keep everything the same and record only when I first saw natural light, why I first left the room, where I first spoke to another person, and when I truly began my main work. In the second week, I would keep the workload unchanged but fix one route: after waking, walk to a shop that requires crossing public space; complete the same task where other people are steadily working; and arrange two weekly demos with a specific person who expects me to show up.
This isn’t about proving “environment determines people.” Quite the opposite: if changing the path doesn’t shift my state, reduce the weight of this explanation and check sleep, body, and mood. If only “someone waiting” works, it shows the key variable is relationships—not city aesthetics.
The test has not happened yet, so I cannot announce a result in advance. For now, I can confirm only this: “Shenzhen made me sink” is too broad and too convenient an explanation for June. The next record should come down to those ten meters—what I touch after waking, where I first step outside, and who knows what I meant to finish that day.
Two weeks from now, I’ll decide whether to change my room, my path, or admit that the problem isn’t on the map at all.
