This question already has an answer here:
I frequently see questions about word-suggestions, something like:
I am looking for a term to describe X.
Questions like this could attract a lot of answers, like this:
You could call it Y.
Or like this:
You could call it A.
you could call it B.
Or like this:
You could call it P.
you could call it Q.
Well, on a third though,
you could call it R.
Obviously, if there is no "correct" (in the objective sense) answer, those who propose more than one suggestions have higher chances of getting upvoted, because one of their suggestions could be quite right. This way every single suggestion they made (in the same answer) rises to the top.
However, for an outsider, it is not at all that clear, that which of A or B got the upvotes, or which of P, Q, or R received the upvotes. So, which one should be choosen by a naive outsider?? Needless to say, that sometimes suggestion A should be heavily upvoted, whereas suggestion B (from the same user within the same answer) should be heavily downvoted.
I believe that answers of this kind are not at all useful, and it is very difficult to correctly vote on those.
Question: what is the rationale behind letting people post multiple suggestions in the very same answer? Is this by-design, or an unfortunate by-product? How do you vote on these answers?
