If one clicks on "Unanswered" as shown in the figure below
one gets a list of questions with no upvoted or accepted answers. But questions with only downvoted answers don't appear in this list. Can anyone explain why?
The curious fact is that, if one clicks on "Questions" and then on "unanswered" as shown in the images, then questions with only downvoted answers appear in the list. I wonder which is the reason of this discrepancy.
