> * Ranking, in general, creates filter bubbles. Do you really think strengthening the filter bubble would help? Discerning between truth and misinformation is also a "filter bubble". Any community-driven system that discerns between "this is what we like" and "this is what we hate" is also being used to discern between "this is what is true" and "this is what is false". Online communities with healthy cultures and downvotes quickly destroy misinformation. In those circumstances, the filter bubble is a good thing. People pushing misinformation should be pushed either to stop posting misinfo or leave. The challenge is that the people who are doing the most work on this subject - like Facebook and Twitter - have chosen to make it invisible. We don't know how Twitter and Facebook rank their posts and replies. But they obviously have invisible powers as leadership to identify which voices on their systems are "good" and which aren't, and give those "good" voices outsized power in communication. But to me it seems obvious that something that takes Reddit's simple up/down interface but combines it with the kind of credibility ranking that Twitter does (where people who've been established as harmful don't actually have as much visibility or influence in the system) would be ideal. Give the leadership tools to establish a preference for fact, and you also give them tools to establish a preference for their particular worldview. You can't separate those. If you want a discussion system that supports fact over misinfo, you need to have a discussion system that enforces a community bias and creates a filter bubble, and then give the leadership the tools to control that filter bubble and bias, in the hopes that the leadership prefers truth over misinfo. Otherwise the community will organically create its own filter bubble on whatever biases it develops. And if you have no filtering at all, you get 4chan, where abuse and misinformation run rampant.
