In the Last few weeks, I saw some posts (questions and answers) downvoted without any comment, especially for posts coming from new comers. I agree some posts don't reach the quality standard we want on this website, but I think putting a comment suggesting edits is more constructive than just downvoting.
I think asking for explanation in comments is not productive as downvoters won't be notified and have no reason to come back to the post to leave a comment.
Is it possible/desirable to not allow downvote if no comment has been written?
EDIT: I think I have to develop some arguments:
- I mostly asking this question because of posts being downvoted more than once with no comment from anyone. If a comment explaining why downvote, I see no problem to upvote the comment and downvote the post.
- for the signal to noise ratio, signal can be increased by educating people, noise can be reduced thanks to the deletion and close mechanisms. Moreover those mechanisms offer simple way to provide reason for the negative feedback
- for references for other SE website, different website already have differences. e.g. Latex.SE require MVE while stackoverflow require the smallest piece of code possible. Moreover, each website has its own community. Crockers rules are obvious for coders but not necessarily for all community. Leaving a comment explaining that is educating people and communities.
- the close and flag button do not require much effort.
- my goal is to share knowledge. Given that goal, commenting and downvoting come together, the first one explaining why the post should not receive visibility.
- new comers may not be used to SE mechanisms. Orienting them to useful resources (e.g. by leaving comments) can make them understand those mechanisms without reject those mechanisms. Thus I'm more able to accept downvote if the post is not from a newcomer.
EDIT: I just add an recent example, downvoted in less than 10 minutes with no comment (so I added one so that the OP knows how to improve it): When an Airforce plane is “Stationary” should you still smell chemicals?
