Links are "DOI NOT FOUND". Article does not seem to suggest that the study actual found any relationship between the increase in the two things, just that they both happened around the same time.

The common demoninator is the rise of social media networks.
smallerize•28m ago
Unfortunately, even for the most fast-moving journals, that time is typically several hours before the actual articles appear on the journal’s website. So, anyone who’s reading quickly is likely to find that the DOI fails.

But that rule only applies to the fast-moving journals, like Nature and Science. Many other journals can take a few days between when they allow journalists to write about a paper and when it becomes available to the scientific community—PNAS, which is a major source of material for us, falls in that category.

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."
txrx0000•25m ago
The problem isn't connectivity provided by the Internet or the average number of friends. Those things are good on their own. The problem is centralized moderation in an infinitely connective environment (aka the Internet), which will create intellectually and ideologically homogenous groups that increase in size without limit.

For details see: https://news.ycombinator.com/item?id=45515980

The solution is to ban all server-side ranking, moderation, and filtering mechanisms and replace them with client-side-only solutions, at least for large platforms above a certain user count like X and YouTube. Same thing for search engines and chatbots.

Each person should be able to control what they can post and view online, but not what anyone else posts or views. The norms that we use to moderate physical public spaces must not be applied to online public spaces. Until we discard those norms, people will continue to become increasingly polarized, democracy will continue to decline worldwide, and violent conflicts will continue to increase in frequency and scale.

This is such a HN response. A HN reader might think it's fun to spend a weekend on writing/testing a ranking algorithm, but not the average person. They're just going to use whatever the platform recommends.

txrx0000•14m ago
We need to ban the platform from recommending at all.

It would be like more sophisticated Adblock. There are many providers of Adblock lists, but they can't be provided by the platform itself.

kiba•11m ago
Most people will use the default algorithm. A minority will choose a different algorithm.

It's only a partial solution. Really, the correct response is regulatory oversight and taxation on remaining economic rent. They are monopolies, and should be regulated as such.

philipkglass•10m ago
It's also impractical even for tinkerers. YouTube claims to get over 20 million videos uploaded daily and it has well over 10 billion stored videos in its corpus. The metadata alone is tens of terabytes. The usual introduction-to-recommendations approaches out there are going to completely fall over on an item set of this size, even if you have disk space to spare.
txrx0000•6m ago
The server can deliver a sparsely randomly sampled RSS feed of embedding vectors and metadata.

Fetch media after ranking on-device.

p1necone•16m ago
In practice I don't think this really changes anything at least for moderation. It takes a bunch of time and effort to moderate online communities - under the process outlined by the post you linked most communities are going to have a single effective clientside moderation list you can subscribe to anyway.

Totally unmoderated internet communities would be completely unusable because of spam, and it's also questionable whether you could even stay up with no serverside moderation - you'd have to delete stuff otherwise it just takes one script kiddie with a botnet to flood your disk space with garbage.

(User produced ranking/filtering algos though I can see being viable)

txrx0000•7m ago
There are multiple providers of Adblock lists. It would be like that, not single-provider.

Regarding banning server-side moderation, we probably can't do it without decentralizing content delivery in a BitTorrent fashion. But even half measures like replacing moderators with client-side filters would be a big improvement.

"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.

0xbadcafebee•13m ago
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.

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.

> "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, and because 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?
