After reviewing both our guidance in the Help Center and related Meta posts (here and here), I thought some community discussion on when to downvote would be useful, especially as the site evolves.
The answer to this question is clearly different across StackExchange communities (e.g., StackOverflow & CrossValidated) and is also affected based on the volume of site traffic.
So, when should I downvote a question?
- What circumstances warrant a downvote?
- Should I downvote when reviewing questions?
- Do I need to comment when I downvote?
