A very obvious solution to groupthink is to do away with the silly voting system. I don’t know why they kept it. A very simple solution would have been to just assign votes to a topic based on how much attention it’s getting. In simple terms, If opposed has 10,000 people that have viewed it, 1,000 people have left a comment, compared to a post that has 100,000 views and 15 comments, you can tell which one should have more attention score. The upvote and downvote system is too easily used as a dislike or like system. Many of us have the maturity to upvote something because we think it’s a good discussion point even if we don’t agree with what the person is saying. But a lot of people don’t think that way mentally. They see something, they read it, immediately go into toxic hater mode and just downvote it for no reason
