automobiles -> suburbanization -> isolation -> mental health crisis seems like a fairly easy hypothesis to test since there are still millions of people in america living densely and carless in places like nyc and you could demonstrate that they have a statistically significant gap in mental illnesses. so easy to test that i bet several people already have and you could just check.

[lazyasciiart]

Yes, they have. And they found it to be correct.

> living in dense inner-city areas did not carry the highest depression risks. Rather, after adjusting for socioeconomic factors, the highest risk was among sprawling suburbs

I can tell you as a resident of New York City that the negative effect of the automobile on the built environment is very much present here as well.

[sambishop]

for sure! but that's irrelevant to a causal chain that includes "suburbanization", since you're not in the suburbs (in manhattan at least, the walkability does drop off pretty quickly)

another interesting tack: how long did we have cars before we started talking about a widespread mental health crisis? is there a more parimonious explanation, like a different event that is located closer to it in time? perhaps smartphones or the internet?

[poncho_romero]

I think you are too focused on one problem caused by cars. Even if they didn't cause mental health problems due to isolation (seen most prominently in suburbia), they cause enough other problems to warrant pushback.

[sambishop]

arguments are not soldiers. i am specifically responding to the claim that cars leads to suburbs leads to mental health issues. i am not a partisan in the greater car wars.

It is not merely suburbanization that has been caused by cars, but also the very urban fragmentation. Immigrants are no longer permitted to live in enclaves, ghettos, or the same neighborhood with one another.

Another thing about "this mental health crisis" is that it has been ongoing for many decades before we noticed it and before it was brought to the forefront. "One Flew Over the Cuckoo's Nest" was out and then President Reagan approved the mass closure of asylums. What happened was that massive numbers of citizens had been condemned and committed by their relatives and "put away" in homes, facilities, and institutions, and then Reagan shut 'em all down.

Today, the mentally ill live among us. Either their families care for them, or they live in jails/prisons because they became criminals and were convicted, or they live independently/on the streets. The mentally ill live now in "virtual institutions" where their chains and restraints consist of drugs. The drugs are what keep them connected to their home clinics and their psychiatrists. The drugs keep them coming back for more, month after month, to their pharmacies and clinics. The drugs they are convinced they cannot live without, making them compliant and unsure of what is really going on in their lives.

The non-criminal mentally ill are mostly encouraged to integrate and socialize, to seek employment and try to simulate functional human beings in society. So they live among us and they are causing more noticeable issues when they interact with people possessed of more sanity. The mentally ill are probably less likely to drive or own a vehicle, and more likely to rely on public transit, so you know where to find them.

But the mentally ill who live independently, and live with these "virtual restraints" are likewise living in fragmented neighborhoods that are not walkable and require a lot of effort to overcome the sheer distances that separate them from services and their employers. They're living among immigrants, foreigners, heathens and infidels, and on every corner is a moral trap such as easy alcohol, easy sex, easy gluttony, easy gambling that can ensnare even the sanest city dweller. These traps are, of course, legitimate businesses that cannot be shut down by a mere vice-squad raid.

So "this mental health crisis" in 2026 can perhaps be partly traced to the advent of personal motor vehicles, but I feel there are several causes that have brought it to the forefront.

You miss how this mental health crisis seemed to emerge in lock step with screentime. Not really suburbs. It is funny when people wax poetic now about the carefree latchkey adventurous childhoods of the boomers or gen x. I mean all of that stuff was little adventures happening in the suburbs. Nothing else to do inside so this is what would happen. You give that kid along with the rest of the kids in the neighborhood, well, tiktok there's your isolation and mental health crisis source right there. At least in the early dialup days kids were kicked off periodically so parents could use the landline, and there just wasn't such a bottomless well of content either to spend all waking time consuming.

EDIT: missed your other reply a few mins earlier alluding to smartphones already

That's a common narrative in popular culture (especially since the publication of Jonathan Haidt's The Anxious Generation), but it doesn't really bear out in data. Smartphones don't really have a discernible impact on mental health at a population level.

The idea is that teen mental health got dramatically worse in the early 2010s at the same time as social media began to become ubiquitous, but this is likely a coincidence. The underlying metrics we're tracking here are self-harm hospitalizations, and concerns about teen self-harm were already growing in the early 2000s. This leads to a bunch of new guidance getting published which increases teen mental health screening, tracks mental health status as a cause of injuries, and forces insurance companies to cover associated costs.

It's one of those situations where our stats about a problem increased as we became better at tracking it. Teen suicidality is actually WAY down over the past ~30 years.

Qualitative data is, of course, much harder to work with than hospitalization numbers, but the data we do have suggests a weak correlation, if any, between phone use and poor mental health— see https://pubmed.ncbi.nlm.nih.gov/30944443/, which suggests phones can explain at most 0.4% of variance in well-being among teens. [1]

It feels like common sense that social media is bad for you, and sure, there's plenty of work to be done in understanding how and why social media can cause harm. But the idea that there's some big crisis just doesn't pan out.

[1]: In fairness, Haidt published a response to this article featuring a new, bespoke set of controls for the data. His analysis suggests that the impact of social media use on mental health is nearly twice as large as that of being sexually assaulted and four times larger than hard drug use (which itself has a slightly larger effect size than wearing glasses). Personally, I don't find these conclusions plausible at all. Maybe Haidt's been p-hacking, or maybe the data set is worthless. I couldn't say. https://www.sciencedirect.com/science/article/pii/S000169182...

you have to deal with selection bias - those are presumably very different groups of people selecting into the type of environment they favor at some level, albeit aconstrained by affordability
