Trump threatens to 'close' down social media platforms

There's an unsolved conundrum I haven't heard mentioned yet.

After the 2016 election, there was a thought that too much false information is spreading on social media. This happens in every country and across every form of communication - but social media platforms seem particularly worrysome (and is particularly bad with Whatsapp forwards in some Asian countries).

So what should the social media companies do? Censor people? Disallow certain messages (like they do with terrorism related posts)?

They settled on just putting in fact check links with certain posts. Trust in the fact deciding institution will of course be difficult to settle. No one wants a ministry of truth (or the private alternative).

So the question remains - do you, or how do you lessen the spread of misinformation?

It's as simple as toning down the virulance and addiction potential that has been baked into social media over the years. Revert to chronological feeds based on timestamp alone, and not sorting based on how many inflammatory comments and shares they have. Ban more pages that produce and share these misinformed posts. These are problems that these engagement algorithms themselves created, and social media companies are too timid to actually solve for fear of affecting stock price.

I don't think reverting to chrono content makes sense. If popularity doesn't influence what's top-of-feed, then we'll just be flooded with un-interesting content.

Imagine if HN or Reddit didn't sort by popularity? Everyone would need to sort through /new. ...that's not scalable.

What would be better would be to reward controversial content. If lots of people downvote something, and also lots of people upvote, then maybe it needs more attention, not less?

So that rather than creating ever-more-extremist bubbles, people are more likely to see opinions that make them force them to appreciate other points of view.
