I think people go to Slate Star Codex, because that's where Scott writes his articles, not because of the voting mechanism.
From the paper:
authors of negatively evaluated content are encouraged to post more, and their future posts are also of lower quality
Seen that at LW a few times. At some moment the user's karma became so low they couldn't post anymore, or perhaps an admin banned them. From my point of view, problem solved.
I think it would be useful to distinguish between systems where the downvoted comments remain visible, and where the downvoted comments are hidden.
I am reading another website, where the downvoted comments remain proudly visible, with the number of downvotes, and yes, it seem to enrage the user to write more and more of the same stuff. My hypothesis is that some people perceive downvotes as rewards (maybe they love to make people angry, or they feel they are on a crusade and the downvotes mean they successfully hurt the enemy), and these people are encouraged by downvoting. Hiding the comment, and removing the ability to comment, now that is a punishment.
"some people perceive downvotes as rewards"
Is this just a dig at people vehemently defending downvoted posts or are you serious in calling this a hypothesis?
Below is a message I just got from jackk. Some specifics have been redacted 1) so that we can discuss general policy rather than the details of this specific case 2) because presumption of innocence, just in case there happens to be an innocuous explanation to this.
So... thoughts? I have mod powers, but when I was granted them I was basically just told to use them to fight spam; there was never any discussion of any other policy, and I don't feel like I have the authority to decide on the suitable course of action without consulting the rest of the community.
