A symptom of the problem is that such threads tempt so many people to express their opinion for the sake of expressing it. I get lured in sometimes too. But when I can stop myself, I just flag the thread. And if I need to feel better, maybe I go through and down vote comments I disagree with in lieu of telling people their political, economic, or ethical views are wrong.
That's better than me just adding to the noise and heat and lack of civility. Downvotes are socially acceptable. So are upvotes.
My concerns can be summarized into a single question - If HN had existed historically with the rules as they exist currently, would Georg Cantor have thrived in it?
I doubt it. Unconventional ideas that are orders of magnitude less radical than Cantor's get reduced to convention and dismissed all the time on HN. It's dismaying. But it is what human beings do, and especially what human beings in groups do. HN can't change that by proclaiming rules. Maybe we can mitigate it a little, such as by asking people to avoid gratuitous negativity.
Holding a dissenting opinion without being willing to defend it with awareness of your audience's hostility to your ideas rarely goes over well in any forum, though.
Then again I am kind of thoughtful when I do and often make sure to point out that I like Apple, and recommend it to others, -I just personally find their products annoying to use for specific reasons
I'm making assumptions here on anecdotes of course.
On topics where there is a deep skew in the opinion held by the HN readerbase, it is probabilistically likely that going against the widely held view will receive more downvotes. This has a chilling effect on expressing dissent. Of course there will be people who will be able to mitigate this with their gravitas and eloquence. But it would be better if we can come up with a scheme where we lower the burden on people holding a dissenting opinion.
If HN is tribal then attacking one tribe while praising the others might be a method to farm positive karma.
Some will, but its very rare that I've seen posts retain a net of negative moderation when they contribute substantially, regardless of the side of an issue they are on (though I've seen controversial-but-substantial comments quickly get heavily downvoted before recovering.)
And I've seen this on every side of issues -- often to opposing posts in the same discussion -- so I don't think its an "echo-chamber" effect, but more that certain topics bringout more kneejerk negative responses from people on either side.
(Its funny that, in regard to accusations of HN being an echo chamber or hivemind, I've seen various posters proclaim with confidence that it was -- and that that hivemind was, variously, liberal, leftist, libertarian, capitalist, pro-corporate, anti-corporate, and in support or opposition to various companies, and any of a number of other things. I think people are way to quick to equate some people disagreeing with or downvoting their posts to HN being a hivemind biased against them.)
I think "Maybe next time it comes up the comments won't devolve."
I once had a few week period where I noticed the majority of my comments drop by exactly 2 karma, usually around the same time of day, regardless of how many upvotes they'd received or how heavily trafficked the thread was. My best guess is that I'd upset two people (or one person with two accounts) and they kept clicking back on my profile until they got bored with it.
I think "in the long run" is key here.
When I make a comment that challenges some band of partisans, but strikes a factual tone, my observations is that it initially gets downvotes (presumably from the partisans who are hovering over the thread/story), but in the end gets moderated highly.
"I do not agree" "I do not believe this adds value" "Inappropriate conduct" "I think you are being mean / rude" "Bad attempt at funny" "Off topic to parent" "Off topic to post" "Difficult to understand/Noise"
What generally happens is that instead of one argument about been downvoted/upvoted you end up with even more arguments about whether something is +5 funny or whatever.
I've no idea how you solve this in the general case tbh.
Personally, I like the idea of having qualifiers on the downvote without one on the upvote - makes you think a little bit before downvoting... plus the vote buttons are ridiculously small on an mobile Safari - so having to click twice would prevent accidental downvotes.
That said, it's not perfect. There are -1 Overrated and +1 Underrated mods. I would not have these if I was king for a day, because:
• They apparently somehow bypass meta-moderation, or have done in the past (!) so not surprisingly they get abused a lot
• They are vague and don't force you to justify what's good or bad about a post, in many cases I have seen abuse of these mod types devolve into reddit style agree/disagree modding
• They don't adjust the adjective that goes with the post, so for a long time and maybe still now you can get posts like +5 Troll or -1 Insightful, which is just confusing and generally bogus
Stripping out Underrated and Overrated would improve things a lot. I'd maybe make +1 Funny count for karma too because funny posts deliver a lot of value to the slashdot reading experience, IMO, and I see no problem with encouraging them.
I think the balance of adjectives is important though. There is no -1 Wrong or -1 Misinformed mod and that's important. If someone posts something polite, earnest and completely wrong there's no justifiable word to mod them down with. Instead you have to wait for a reply to correct them and then mod that up as Informative, Insightful etc.
PG has stated in the past that downvoting things you disagree with is proper usage on HN: https://news.ycombinator.com/item?id=658691
I don't know if 'dang has changed this policy, but if so I haven't heard about it.
Sounds great in theory. But then a small number of zealots can derail just about every thread with minimal effort. I image it would really degrade a community in a heartbeat. So it's probably a good thing nobody has found a way to enforce such a policy.
