Several people posted recently in a thread on women, mostly espousing feminist views - only to find that someone had declined to respond to their post, but instead browsed their history and downvoted every single comment or article they had ever posted.
I have two questions:
1. Why would you come to a site like this and pollute the karma system? How does it make you smarter? How does it make anyone else on the site smarter?
2. What would be a good technical workaround? In my mind, some system that detects mass-downvoting and flags a user for review would be preferable, but what should happen then? Should the system be more lenient to higher-karma posters? Who should perform the review process? What should be done with those whom the reviewer ascertains are abusing the karma system? I would prefer some kind of lesson that is more corrective than retributive - it seems to me that people who would perform this behavior are exactly the sort of people who need some of the lessons that this site provides. Any ideas?
It is also very interesting to notice that the subject is charged enough to provoke this kind of behaviour. I don't think it has ever happened on a discussion about a technical fine point of some decision theory.
This evidence increase the probability I have on the hypothesis: "LW crowd has totally failed in raising his own sanity waterline, on average. There are people who undoubtably increased their own, but they are more than compensated by people who get even more irrational on a rationality forum."
Do you have evidence that favors that hypothesis relative to "The general improvement in the sanity waterline at LW is sufficiently small and poorly distributed as to make no difference among a large fraction of users when it comes to emotionally charged topics, even though both the mean and median user has raised their sanity level."?
