Given the following post, respond as if you're commenting on Reddit:

CMV: You shouldn't be able to see how many upvotes/down votes a comment has until after you have upvoted/downvoted.

One of the most annoying things about Reddit is how often comment sections turn into circlejerks. Echo chambers are harmful to rational discussion, and should therefore be avoided

All it takes is five people to disagree with you for a comment to be hidden and buried, which makes any comment that isn't in line with the prevailing orthodoxy effectively invisible. Having comments be hidden isn't necessarily a problem, but what is a problem is how often comments get mass downvoted just because they're being downvoted. Humans like to feel like they're on the "right" side, so they are extremely susceptible to group think and letting their opinions be influenced by popular trends, so when someone sees a discussion where one commenter has 20 upvotes and the other has 10 downvotes, they will be naturally predisposed to favour the upvoted comments. The problem is, of course, that you don't know how many of those upvotes/downvotes were themselves people just following the trend, so the issue just snowballs. I've seen plenty of fairly reasonable comments get downvoted into oblivion one day, and then the next day on the same sub a comment echoing the same sentiment might have hundreds of upvotes.

Psychologically, this is often a subconscious process since, while we like to feel as though we are right, we also like to imagine that we are rational free-thinkers. Therefore, I think a solution would be to have a comment's score be hidden until you vote on it, with a short time limit on altering your vote. This way, people would have to judge it independently and for its own merits, and following the crowd would have to be an active and conscious effort rather than a passive, subconscious bias. I don't think many self-respecting people would be willing to change their vote after the fact to be in line with the majority, and people are more likely to stand by their own independent thoughts when they have to actively think about whether they're letting others influence how they think.

Upvotes and downvotes generally determine where comments are displayed in a thread. Top-rated comments are displayed first. Low-rated comments are displayed later. How do you propose we display comments with your system?

Ideally, upvotes should be used for things that are deemed to add value to the discussion, while downvotes are a way to eliminate trolls, jerks, and low-effort posters. The bigger problem is that people disagreement downvote.
