I favor the theory that polarization is due to decreasing attention spans, effectively preventing us from appropriately considering nuance.

Agreed, there's so many headlines on X and Reddit that are obviously highly spun and could take 5 seconds of reading into it to see through the BS. But they kill as long as people agree with the phrasing and people go right to the comments to cheer it on instead of reading the article.
It's tough on the internet being a skeptic or generally thoughtful about the world. It's not even worth debunking stuff anymore. Much healthier to not engage entirely.

I can no longer engage in (controversial) debates on other social medias, as responses often indicate a lack of understanding with the other person - they glance over the arguments, make a prejudice-based opinion, and then they respond to their straw man, often loaded with bad emotions. It's quite frustrating and as you say, sadly only solution is to disengage, but in so doing the polarisation only increases as dissenting opinions are removing themselves.

> but in so doing the polarization only increases as dissenting opinions are removing themselves.
It used to make sense when the internet was smaller but now? Not so much. Especially when the people running platforms/media, content moderators and influencers explicitly don't care about the truth. You're not just fighting some dummy posting a comment.
The only positive thing I've seen in the last decade to address this was Community Notes on X.

That's one of Chomsky's major points for decades.

Curious for the source? To my recollection, Chomsky talked about distraction, i.e. repurposing attention. OP is talking about the pool of attention as a whole drying up (versus being misdirected).

embarrassingly haven't dug into Chomsky, this is another update towards me doing so soon!

OT: As someone in the same camp, does anyone have any recommendations on where would be best to start?

i think this is a good article, but these statements,
> If populism is merely a strategy, not an ideology, then why are certain ideas seemingly present in all populist movements (such as the hostility to foreigners, or the distrust of central banking)? > For example, why are “the people” always conceptualized as a culturally homogeneous mass, even in the context of societies that are quite pluralistic (which forces the introduction of additional constructs, such as la France profonde, or “real Americans”)?
... are not quite as applicable to left-wing populism (for the latter --- at least, at the surface). post-colonial, _left-wing_ populism tended to be of international character, or at least of wider appeal than the nation (e.g., nasser). the "distrust of central banking" is of wildly unique impetuses for left- vs. right-wing populism.
the common-sense point is quite poignant, at least for me in the u.s., where each party paints their own solutions as explicitly "common-sense", for solutions as unique as harsh border control ("solutions") vs. city-owned grocery stores & free childcare.
there are certainly issues i imagine i don't hold the "elite" view on. many people don't consider the "elite" view at all --- anti-punitive justice, for example, is rejected for particular types of crimes, despite provenly worse outcomes if we simply punish these crimes. the rise of anti-intellectualism doesn't help :D

> "Despite minor differences between individual surveys, the data consistently show that the average number of close friendships rose from 2.2 in 2000 to 4.1 in 2024," says Hofer.
If true, this is an astonishing social transformation, because it goes against everything we here about the loneliness epidemic getting worse.
Or have people redefined what they consider to be "close friends"? Or are people actually genuinely maintaining more friendships because phones make it so much easier to message?

It could also be something structural about how the "friendship graph" looks. The mean number of friendships isn't the median or typically experienced number of friendships, and if friendship relationship distributions follow some kind of power law, a change in the power-law exponent could make those diverge.

Personally, I find modern technology makes it easier to maintain them. 25 years ago my friendships around the world would have been relegated to 'penpalships' because of the cost of long distance calls and the lack of face time.
Loneliness is a big topic now due to the pandemic, and the lingering trends from stay/work-at-home mandates.
kulahan
They probably aren't the friends people are thinking of when referring to things like this. The benefit of friends isn't just that you have someone fun to talk to, it's that you're building out a social support circle. Your discord friends can't come over and help you clean up after a flood, or watch your dogs while you're away on a sudden emergency, or cook you a meal when you're grieving a loss, or help you get an interview at a job shortly after you're fired (or at least, not one local to you).
Loneliness is a big topic now, imo, because people are losing helpful human friends and relying on middling digital friends. Just like how looking at pictures of a forest is nowhere near as healthy as actually going to a forest.

I'll make the counter argument that -- although I value those things and try to provide them to friends in need -- all of those can be addressed by hiring someone.
On the other hand, I've recently received fantastic emotional support from a friend who moved away a few years ago. We've seen each other in person only a handful of times since then, but of all my friends, she happened to be the one with the experience and attitude to help me.
Incidentally, I'll add that I'm the type of person to provide those types of support to others, but the vast majority of my friends are not. That doesn't make them bad friends, it just means that I have a service disposition while they don't. I think there's a vast range of qualities that people seek and experience from friends and you're going to have a hard time objectively rating them on any sort of scale.

Keep in mind that it is "average" and it is about close friends.
Anecdotally, the pandemic was the great cutting of weaker ties. I talk to far fewer people than I did pre-pandemic (and most friends report the same), but I speak to those people more often. I can easily see that ending in a way where some 20% find themselves with nobody.
I would say I have 4 close friends. But some 10 weaker ties disappeared from my life. Did those 10 also double down on close friends? Or did perhaps some of them not have enough close friends to do that?

Many of my friends live abroad. We started a weekly Zoom meeting during Covid-19 lockdown. Now we have a WhatsApp group too. Does that change the classification from plain friends to close friends?
yieldcrv
Oh god flashback, I remember the zoom calls, and people acting like they didn’t know how zoom worked 10 months into it or that the host can mute anyone that doesn’t know how to mute themselves
I opted out of the extended family ones and the social ones
I wonder if they’re still doing that, I’d rather watch paint dry, which I did for a few months in San Francisco
jerlam
I would agree - usually close friends are limited to people that share the same values and ideas as you. Having more close friends that all think alike would increase rejection of ideas not shared by other close friends. It is harder (but not impossible) to have close friends that have dramatically different lifestyles, ideals, or socioeconomic class.
Weaker ties would include friends that have less in common, and have different ideas. But that fact that they are a friend means that you are aware of their existence and different ideas. In that way, having a broad range of weak friends suggests that you can see things from different perspectives instead of in your own (close) friend bubble.
It's like how people are less likely to know their neighbors now, who can hold different ideas. But you don't have to be close friends with them to have some empathy.
JumpCrisscross
> usually close friends are limited to people that share the same values and ideas as you
That stirkes me as myopic. My closest friends--the ones I trust with all my secrets, with whom have have practically no secrets, the ones I'd hide if it came to that or risk my life to save--are all over the place values and ideas-wise. It's what makes their company fun. It's also what makes their advice useful, because they'll call me out on my bullshit in a way a mirror image of me could not.

Or women have 8 and guys have 1
watwut
When you look at studies, women and men are lonely at about the same rate. There are differences at the margins - period right after divorce, being stay at home and such. But overall rates are the same.
cowpig
I can't find any evidence supporting the claim in the article, and the study it links to for me is a dead link. Are you able to find the source?
bossyTeacher
> have people redefined what they consider to be "close friends"?
Yes. People nowadays spent 8 hours per day chatting to someone online and they call it close friend even if they never met in real life.
Also, people nowadays are notorious for being unable to have friendship that is not a [insert activity here] buddy.
ToucanLoucan
I have a sinking feeling it's a situation where people who are adept at creating and maintaining relationships are getting more of them, whilst people who struggle socially are being excluded more than ever as a result. The overall count grows, but a substantial slice of the population still has barely any.
I have no data for this, just a gut feeling. I still see so many people on the day-to-day who are completely socially inept. I don't even mean just like, rude or abrasive, I mean people who don't have the emotional intelligence to like, navigate basic conflicts.

In-group dynamics are further ingrained as the group gets bigger. If you have 4 friends in a group, their opinions aren't as strong. If you have 40 friends in a group, not only are their opinions stronger, they'll fight vigorously to defend the group's commonly accepted beliefs. So a growing social circle does reinforce the group dynamic. (this is well established by lots of studies)
But increased polarization around the world isn't because of this. There's the typical environmental factors: an increase in changes (or challenges) to traditional values increases polarization; an influx of migrants increases polarization. But then there's also social media, where mastery of "engagement" by businesses for profit has been adopted by political groups looking to sow division to reap the benefits of polarization (an easier grip on power). The rapid rise of polarization is a combination of both.
It's nothing new of course, political/ideological groups have been doing this forever. We just have far more advanced tools with which to polarize.
txrx0000
Before the Internet and social media, groups had a practical size cap because they had to meet up in person. Polarization was naturally limited.
I don't think the social media companies' algorithms are entirely to blame. But more broadly it's centralized moderation of public online spaces.
Moderation of public behavior of physical spaces was only necessary because it wasn't possible to selectively filter people's influences on eachother in public. If someone is doing something you don't want to see in public, covering your eyes is not good enough because you also block out the people you do want to see. Centralized moderation was a practical half-measure rather than an ideal solution for a democratic society that values free expression and self-determination.
That kind of moderation isn't necessary online because all filters can be implemented client-side. We just aren't doing it because people are so used to the old way. But the old way will naturally lead to more and worse conflict when we have infinite connectivity.

"An information flow model for conflict and fission in small groups (1977)" by Wayne W. Zachary [https://www.jstor.org/stable/pdf/3629752.pdf]
I know this paper isn't about social networks, but we know this, we knew it in the 70s. The only difference is that we continue to ignore and forget it.

I’m more interested in how people determine who they trust, and the parameters by which humans decide to trust someone.
I would wager that people are shit at determining trustworthiness based on limited information (like social media representations). In the old days before social media, you got to know people in person, and decades ago, most of the people you knew were likely people you grew up around. You knew that person’s background, how they treated people, what their family was like, and what likely influences them as a person.
So much of how we process trustworthiness is how we perceive the motives of the speaker. With shallower friendships and parasocial relationships, we want to feel connected but really lack any good context that you need to actually know who you’re listening to.
DavidPiper
The fact that we have more close friends on average is a novel and surprising observation to me. Very worthy of investigation.
But, how is moving from a circle of 2 close friends to a circle of 4 close friends a significant enough jump to "fuel polarization" on a societal level? There's also a 10-year gap between USA (and other countries' data points too) that covers the span of the whole alleged "aligned trend". It feels a little bit like the authors just went "Look! Two data trends moving in the same direction! Causal?!"
More seriously, I would love to see a much deeper dive on:
- Technological and associated psychological trends that might be causing greater polarisation (plenty of existing data here)
- How an increase in close friends can co-exist with an apparent loneliness epidemic (plenty of existing data here too)
MattGaiser

You add 2 close friends and to fit them in, axe 10 weaker ones.
JumpCrisscross
> You add 2 close friends and to fit them in, axe 10 weaker ones
I did this after Covid. Consciously started declining invitations from acquaintances, and instead making time and travel to see close friends. Would never go back.
DavidPiper
In this case it sounds like the polarisation is fueled by the axing and not the adding?
grdomzal
> 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
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.

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

better connectivity -> people finding better friendship matches -> groups are more homogenous -> more polarization
txrx0000
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.
HPsquared
Self-actualisation often leads to conflict.
zkmon
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
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
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.

The study linked at the beginning of this article, and the two listed under "More information" at the bottom all take me to a page with the error
"DOI Not Found"
Given that the main (only significant) fact cited in the article goes against everything else I've read, I would like to see the actual study and how it came to the conclusion that the number of close friends has doubled.

This always seemed intuitively inevitable if you ever played with a graph layout tool like dot or similar kinetic layout engine. With weak connectivity the nodes don't cluster readily, but with more connections they "snap" into rigid subassemblies. It always seemed to me like a bad thing for society but it could well be a case of "old man yells at moon."
HPsquared
In the limit you get periodic crystal structures when connectivity is maxed out and fully optimized.
> When people are more connected with each other, they encounter different opinions more frequently. This inevitably leads to more conflict and thus greater societal polarization
If this is true, it is counterintuitive, and runs against the prevailing narrative that living within your bubble and not interacting with opposing viewpoints is what causes polarisation. I thought cities were supposed to be less polarised because people can't help encountering other viewpoints.
