I recently asked this question: Whose responsibility is it to design test cases?.
On its face, it seems like a question with a definitive answer (eg. "The responsibility lies with ..."). The thing is, I honestly don't know which of the answers is the right one. They all bring up very good points, some are more general than others, and they don't all agree.
If this had been a programming question, either on Stackoverflow or elsewhere, it would have been easy to choose an answer to mark correct: it would be the one whose solution I applied successfully, and which contained the most helpful explanation or information. However I'm not sure how to decide what the "right" answer is for a "soft" question.
How do I choose an answer for this kind of question? I want to avoid personal bias (eg. "I'm choosing this answer because I'm upset and your answer vindicates my feelings of frustration"), but at the same time I'm not sure that leaving it up to a popularity poll via voting is correct. Or is it equally valid to not "accept" a single answer?
