I originally wrote this as a comment on a post which had negative net karma when I first saw it. I figure what I wrote is worth also posting to the top level, so that it can have more chance to be seen and thought about
When I came upon this post, it had a negative karma score. I don't think it's good form to have posts receiving negative net karma (except in extreme cases), so I upvoted to provide this with a positive net karma.
It is unpleasant for an author when they receive a negative karma score on a post which they spent time and effort to make (even when that effort was relatively small), much more so than receiving no karma beyond the starting score. This makes the author less likely to post again in the future, which prevents communication of ideas, and keeps the author from getting better at writing. In particular this creates a risk of LessWrong becoming more like a bubble chamber (which I don't think is desirable), and makes the community less likely to hear valuable ideas that go against the grain of the local culture.
A writer who is encouraged to write more will become more clear in their communication, as well as in their thoughts. And they will also get more used to the particular expectations of the culture of LessWrong- norms that have good reason to exist, but which also go against some people's intuitions or what has worked well for them in other, more "normie" contexts.
Karma serves as a valuable signal to authors about the extent to which they are doing a good job of writing clearly about interesting topics in a way that provides value to members of the community, but the range of positive integers provides enough signal. There isn't much lost in excluding the negative range (except in extreme cases).
Let's be nice to people who are still figuring writing out, I encourage you to refrain from downvoting them into negative karma.
Low positive and actively negative scores seen to me to send different signals. A low score can be confused for general apathy, imagining that few people having taken notice of the post enough to vote on it. A negative score communicates clearly that something about the post was objectionable or mistaken.
If the purpose of the scoring system is to aggregate opinions, then negative opinions are a necessary input for an accurate score.
Strikes me as inelegant for the final score to depend on the order in which readers happened to encounter the post. Which would happen under this rule, unless people who refrained from voting were checking back later to deliver their vote against a post they thought was bad, once its score has gone up enough to do so without driving it negative (which seems unlikely).
Avoiding negativity would also negate the part of the system where accumulating very negative karma can restrict a user from posting so often.
I see your point regarding different results depending on order of how people see the post but that’s also true the other way around. Given the assumption that less people are likely to view a post that has negative Karma, people who may actually turn out to like the post and upvote it never do so because of preexisting negative votes.
In fact, I think that’s the whole point of this scheme, isn’t it?
So, either way you never capture an „accurate“ picture because the signal itself is distorting the outcome. The key question is then what outcome one prefers, n... (read more)
