ELI5: Why does reddit some times hide the scores of comments?
gpt
It prevents groupthink. We have a natural tendency to agree with our peers and are impressed by early success. 

If you see three comments all at +1 and then one comment at +3, you may subconsciously think "the one at +3 must have more merit since it's higher", so you're more likely to upvote it yourself. Hiding scores for the first hour or so dramatically reduces this form of groupthink and promotes comment success more based on merit than whatever the first person to read it though.
