I see karma on posts fluctuating (in particular going down) more than I would expect coming from other vote-based websites. Is downvoting really used here for posts that are not spam or trolling? Or do people just change their minds a lot?
The FAQ has: We encourage people to vote such that upvote means “I want to see more of this” and downvote means “I want to see less of this.” But I guess I’m surprised if people actually behave that way? And that some posts are controversial enough to receive active downvotes vs passive ignoring.
Okay, I admit my model was oversimplified. No, I wouldn't recommend downvoting all AI content. It's a pretty core part of the site, and a lot of core users care about it. It's like turning up to a forum for software engineering enthusiasts and downvoting everything because you're primarily interested in discussing national politics in your country. It would be a waste of effort.
(FYI If you don't want to see the AI content, you can now use the tags to exclude / reduce the amount of those posts on your frontpage.)
Neither the extremes of "Vote how you think others will vote" and "Vote with no regard to the context of the site + its community" are accurate. The main thing I mean to say is that "Vote how you think others will vote" has a lot of pathologies, related to things like first-past-the-post voting systems and market bubbles.
(What is the correct simplified recommendation? Perhaps it is to vote mostly on the average and occasionally on the margin. This is a site for rationality content, and lots of other smaller things like AI, world optimisation, practical advice, and so on, and as part of this site's community you can help out by upvoting and downvoting good/bad content in those areas. You can also help out by adding your taste, where you see things you feel are underrated or overrated, and adding votes there too. I'm not sure how to put into words the right way to combine these things, although I do it myself very frequently.)
