I fully agree with the statement, although the solution may be difficult. In general, there has to be a way to give negative feedback. Without any correction feedback loop at all, the worst of the worst is thriving.<p>Negative feedback is not just for consensus, also as a quality filter. I'll start with the example of Medium, the blogging platform.<p>The idea of this platform is to encourage long form high quality writing. But that's not what's happening. Every topic is hijacked by people gaming the system, producing endless streams of lazy articles that lack any original thought, any sources, nuance, any quality.<p>There's no way at all to give negative feedback other than blocking each individual author or writing a critical comment. Both don't solve the problem. I consider it an existential problem for the platform as only crap comes to the surface. Why would I possibly pay for this garbage? There has to be a way to clean the garbage.<p>So here, the idea of negative feedback is to serve as a quality filter.<p>On Twitter, it's a different use case. It's to reduce harm. Twitter is an outrage platform. Saying dumb, extreme, unhinged things will maximize engagement. The goal of negative feedback here would not be to censor anything, instead to tell the algorithm to dampen the "spread" factor. Show the post with lots of negative feedback less prominently in timelines, which will reduce the amount of retweets, new followers, etc. Somebody consistently extreme should not be rewarded for it.<p>Arguably, on Twitter it's going to be difficult. The way things work currently is their business model. Further, there's the mob mentality likely to abuse any such mechanism.<p>I'll end with an example where negative feedback is implemented extremely well. It's the dutch site tweakers.net. They have a pretty sophisticated comment system.<p>You vote on individual comments roughly like this:<p>-1: troll, offensive
0: off-topic, irrelevant
+1: on-topic (this is the default level)
+2: informative (enriches the topic)
+3: excellent (well researched essential addition)<p>So you give a quality vote, not an opinion/agreement vote. Some people still opinion vote, say a comment like this:<p>"Microsoft sucks"<p>And then give it a +3, instead of the -1 or 0 it should get. Do this a few times and they take away your voting rights entirely. You get one chance to get it back by begging, and if you promise to better your ways. Screw it up again and it's gone forever.<p>A fairly involved system, which will obviously not work everywhere, but it's really good.
