For example, if a user comes across a post that’s been voted as 90% true, they’ll probably be like “I don’t need to think critically about this because the community says it’s true, which means it must be true.”
yeah, it's an interesting--and i'm not necessarily sure solvable--question of how you can design something to usefully combat misinformation which itself won't eventually enshrine or be gamed to promote misinformation in a website context. twitter's context feature is only selectively useful and a drop in the bucket. youtube has those banners on certain subjects but i'd describe them as basically useless to anyone who already believes misinfo.
I'm really skeptical about this. I feel like it could make misinformation even worse. By letting users democratically label things as "true" or "false", you're encouraging users to rely on groupthink to decide what's true, rather than encouraging users to think critically about everything they see. For example, if a user comes across a post that's been voted as 90% true, they'll probably be like "I don't need to think critically about this because the community says it's true, which means it must be true."
