Study finds growing social circles may fuel polarization(phys.org)

> And this increase happened suddenly, between 2008 and 2010

Occam’s Razor tells me that it’s almost certainly linked to the near-total failure of the economic system (and the very slow recovery outside specific US cities).

It is obviously social media: more connections does not equally mean social interactions - people substituted costly and hard in-person for cheap and easy online interactions, with AI optimization fueling the polarization.

> It is obviously social media

I get why social media could possibly be the cause but what makes you so certain it is the cause or the largest contributing factor?

It would correlate well with the social media boom in the late 2000s. Digg, Reddit, Twitter, Google's purchase and aggressive expansion of Youtube, etc. 4Chan.

When did algorithmic recommendations (by which I mean injecting content into your feed to maintain attention, rather than an attempt to rank by quality) become commonplace? ISTR Youtube was being criticised for pushing conspiracy theories in the late 2000s, but I could be misremembering the timeline.

It is just as obviously late stage capitalism - as everyone is busy working 10-12 hours just to survive you have zero time left for costly and hard in-person interactions.

Lol what caused this, it couldn’t have been a major financial collapse that happened around 2008, that’s what radicalised me. It must be caused by people talking to each other.

I noticed this when I studied abroad in the Netherlands — a highly educated, slightly more digitalized country than my own. Politics there splintered into micro-parties, each “hardly exchanging between bubbles,” as the study puts it. First impressions were warm, but dates always ended with splitting the bill. Friend groups felt just as closed off, except for Dutchies who had just as me lived abroad before, learned to bridge cultures and still are my closest friends today.

Digitalization and the pursuit of perfect information seemed to invite more binary thinking — and with it, more opportunities to disagree every single day. Meanwhile, other forces found easy consensus on simpler, more immediate issues: cheap gas, housing, grocery prices, job security, immigration. Complex, long-horizon topics like the climate crisis rarely stood a chance.

When I was in Amsterdam I was with a group of acquaintances of a friend who lived there. One of them offered me an extra piece of pizza they had when I showed up. When the bill came, they asked me for the exact percentage of the bill that that piece of pizza cost. First time experiencing something like that.

I also offered to buy several people a drink while I was there. This was received every time with suspicion and I was treated as if I was trying to gain something transactional besides a simple friendship in the moment. It was an interesting part of that society to experience.

Nordic social norms like this get made fun of all the time by westerners and southern Europeans. A lot of people will take the crappy socioeconomic situations of non Nordic countries just so that they can have warm relations with their families and a culture that doesn’t hate loud noises.

4 western countries with aging populations, what they really found is that people are getting older, have more free time for friends, who are now interest oriented rather than work or school related.

better connectivity -> people finding better friendship matches -> groups are more homogenous -> more polarization
txrx0000 10/27/2025||
I think the causal relationship is not quite that way.

better connectivity -> destroyed physical limits on group size -> groups not only get larger but also more ideologically homogenous because they're moderated by a central authority like how physical crowds are moderated -> people make friends more easily in those homogenous groups OR get kicked and start their own group, which also has the potential to get larger and more homogenous without limit -> groups have larger differences and clash harder

More friends is a symptom rather than a cause.

Self-actualisation often leads to conflict.

For years, I have had very few close friends, fewer than mentioned as previous average, I’ve withdrawn almost completely from social media, and I’m still polarized, because there are only two major political sides in the U.S., and which news source you listen to drives your opinion.

> The sharp rise in both polarization and the number of close friends occurred between 2008 and 2010—precisely when social media platforms and smartphones first achieved widespread adoption. This technological shift may have fundamentally changed how people connect with each other, indirectly promoting polarization.

Indirectly? Seems to me that this is far more likely the "direct" cause, given what we know about the psychology around algorithmic feeds.

Also - I'm not sure if I missed it in the article, but did they define what they mean by "close relationship" means? I'd be very curious to know if a purely online relationship is counted and how this may also contribute to the observations made.

patrickmay 10/27/2025|
The article said that a close relationship is one where the other person can influence your views. I didn't dig into the details to see how that was measured.
phito 10/28/2025|||
Wow that sounds like an awful definition. People get influenced by random comments online...

Thanks! I tried clicking into the linked research paper but got a 404 >.<

Yes, the The People's Front of Judea and Judean People's Front are irreconcilable.

> What disappears as a result is a societal baseline of tolerance—a development that could contribute to the long-term erosion of democratic structures. To prevent societies from increasingly fragmenting, Thurner emphasizes the importance of learning early how to engage with different opinions and actively cultivating tolerance.

That could be a problem, considering how the push back to "actively cultivating tolerance" has unfolded so far.

spencerflem 10/28/2025|
They’re illegally sending the military into the streets to oppress us. I don’t think tolerance is really the move

Polarization maybe a bit unclear word here. Connectivity creates cohesion, which creates larger creatures. So what we have is, virtual monsters roaming around with huge human groups riding on them. They can organize real protests, polarized opinion and massive impact wherever these monsters go.
zwnow 10/27/2025|
Monsters is a interesting choice of words. Why call it monsters?

Isn't polarization a good thing? If I was enslaved by tyrants making my life worse everyday, shouldn't I be opposed by their ways?

txrx0000 10/27/2025|||
More polarization is good if people are allowed to naturally polarize in different directions. Alignment between individuals are supposed to emerge naturally, forming small groups that are internally polarized in the same direction. Democracy would work fine in that society.

But now we have huge online mobs that are homogenously polarized that want to kill eachother. It gets violent when the group size reaches the nation-state level because that's where most of the violence and oppression in our society is siloed.

We have to limit group sizes online. Before social media, it was physically limited by the difficulty of meeting up in person. But now groups just keep getting larger and more homogenous.

That wouldn't create polarization, it would create extremely strong cohesion since everyone else enslaved by those tyrants would agree with you.

I dont know, stockholm syndrome exists and I feel like its very relevant in modern society considering how many people are bootlickers for their employers.

I agree that people with an anti humanistic worldview being able to network is very dangerous. But most polarization I've personally witnessed are people not wanting to live in a system that heavily favors the rich without forcing them to contribute in the same amount poorer people do. People just wanna buy houses and be able to afford a family, while houses are being used as speculative objects by the rich.
