I don't upvote when I don't understand the answer

Often other people post answers, to questions which I don't know the answer to.

If I read their answer, and suspect that it's a good answer, even so I don't upvote their answer because I'm not certain that it's correct, because I worry is that the sequence of events might be:

  1. Someone posts a difficult question
  2. Someone writes a plausible but incorrect answer
  3. I read the answer and (being ignorant) think "it looks good to me", and (being careless) I up-vote it
  4. The next person who reads it sees, not only a wrong answer, but an up-voted wrong answer: my up-vote will have made the problem (bad answer) worse, and would be wrong speech.

Therefore there are answers which I don't up-vote, because I'm not sure of them: they're not bad or boring answers, they are answers to difficult questions.

I don't upvote if I think it's not a good answer

Theoretically there might be another, completely different reason for not up-voting an answer: which is that the answer isn't very helpful.

Can we tell the difference between different kinds of upvote? What does it mean if an answer has no votes?

Here's a proposal: if you read an answer that's not helpful, if you don't want to up-vote it because you think it could be better, if you see a way to improve it, how about add a comment to criticize it?

At the moment when I see an answer with no up-votes and no comments, I can't tell the difference between:

  • This might be a good answer but there's no-one competent enough to judge (up-vote) it
  • There are people competent to judge and they have decided that it was not worth up-voting

If you answer this question feel free to include personal answers: e.g. "yes, criticize my answers" or "no, don't criticize my answers" and/or "I do/don't like to criticize other people's answers".

I admit that criticism can seem dis-harmonious, and that SE is not intended for discussion/dialog.

OTOH some people post answers in public, not only to help others but in the hope that if their answer can be improved, someone will point that out.

    The standard is: "this post is useful." That is a fairly easy bar to reach, so I would encourage a lot more upvoting. Often I go along and upvote every question and answer that I read, and many of the votes were 0 before that. Sometimes I reach my vote limit for the day, at which I think "job well done!" – user2341 May 27 '17 at 14:30

Re: voting, if you don't really understand an answer, do not vote.

Re: criticism, I only downvote and criticize an answer when I see the topic clearly enough that I can be certain that my understanding is complete and the answer is mistaken.

If you have only a vague understanding of the topic, and can't really follow the reasoning of the answer, but the answer seems to mismatch some postulates/axioms you have heard about, ask a new question!

    Yes. A consequence of that is that expert answers to difficult questions may have few up-votes. sigh – ChrisW Oct 9 '14 at 15:04
  • I obviously prefer it if you post a critical comment when you down-vote. In this topic I'm suggesting going further: post a (less-critical) comment if for some reason you decide to neither up-vote nor down-vote. – ChrisW Oct 9 '14 at 15:07

    I get it, and my response to your suggestion is: if your comment were to be based on my answer mismatching some of your preconceptions, but you don't clearly see that the answer is wrong, I would appreciate if you asked a new question. – Andrei Volkov Oct 9 '14 at 15:13

    It's also reasonable to post a comment asking for clarification of a concept you don't understand. This may prompt the answerer to provide more information in the answer, or at least point you in the direction of further reading. This makes the options: 1. upvote a good post; 2. downvote a post if you're sure it's bad; 3. comment if you need further information to understand and judge the answer. – hairboat Oct 9 '14 at 17:46
  • @abbyhairboat, right, I think what we're trying to understand here is a fine line between a request for clarification and a challenge. My position is, if you have doubts but generally agree with the answer, feel free to clarify in a comment. But if you feel the answer is off-base (but are not certain enough to directly point out why), I personally would rather see your challenge in a separate question. – Andrei Volkov Oct 9 '14 at 18:17

  1. If an answer is bad (useless or worse), then you should down-vote it and leave a comment. The comment is:

    • To tell the person who posted it why it's down-voted, so that they can (if they wish) improve or delete their answer
    • To warn other readers that there may be something wrong, and specify what you think is wrong, so that they can judge for themselves.
  2. If you totally don't understand an answer then you can ask a separate question. If there's an expert answer which contains several complicated expressions, which were intended as an answer to the original question, it doesn't make sense to question those too much:

    • Because comments aren't a suitable place for expert answers: asking a separate question allows room for one or more corresponding answers
    • Because changing the subject might detract from the original question and original answer
  3. If you see an answer you don't really like (which is "meh"), make sure that a better answer exists even if you have to write that answer yourself. You can write a whole answer; or just write a partial answer, for example instead of asking someone to add to their answer, you could write,

    In addition to the other answers, ...

    or

    Further to so-and-so's answer, ...

  4. Comments to an answer are for minor conversation about that answer, between you and its author. You nearly understand something but not quite, or you're not sure? You think you understand, but maybe the answer can be worded in an alternative way? Then comment. The author can:

    • Ignore the comment
    • Reply to the comment
    • Edit their answer
    • Flag the comment as unhelpful

About me:

  • I like to comment occasionally, e.g. to verify whether I understand an answer
  • I hope I don't mind receiving comments on my answers
  • Feel free to delete any comments of mine if they are not or if they stop being useful
