Sometimes I upvote a post because I think the potential discussion has merit here, regardless of the link. I have either never downvoted, or only once, to something completely inane and not helpful to the discussion. I really try not to fall into voting based on agreement, since my opinions can and have changed as I learn more. Still, there's a fair amount of subjectivity behind my upvoting, coupled with often choosing to move on to the next dopamine hit rather than thoroughly dig in.
Data on our voting behavior would be interesting. Is it already collected and analyzed by a subset of people behind HN?
What is your motivation for this, beyond that it would be interesting, helpful to mods against abuse, and more transparency as to why the vote? That all may be enough, of course, especially the latter two reasons. More transparency and accountability might make discussions even less prone to devolving into emotional reactions?
i'd say it adds an extra layer of personality politics and further excuses for discussion and bad feelings around the schoolyard level socialization. makes real discussion of subjects more difficult.
I think if i was designing a forum implementation i might go further the other way: not just votes but comments being anonymous, at least at first glance. perhaps have a link on each comment to show the user who wrote it etc.
I think that might increase the signal just a bit, the less "extra" there is around our words, the more need to craft them so they stands on they own
I don't really down vote. I don't recall the last time I did. Also, I don't agree with the mindset "I don't like it so I'll down vote it." It's annoying when that happens. To me it feels small minded and lazy, and it lack intellectual wherewithal.
