This is an issue only for meta, as a question without an answer can be used as a dupe target on meta, not on the main sites. Changes to "close as duplicate" (part deux) (thanks to Laurel for the link)
For the sake of clarification I'll call this question 1 and this question 2.
Question 1 was asked first and has no answers, they had similar upvotes question 2 has an answer.
Question 2 was marked a duplicate of question 1.
Usually when a question is marked as a duplicate of another, one is curious to see the answers on the dupe target.
Isn't it a better idea that the question with the answer is the dupe target?
At least if you disagree, perhaps an argument can be given with not, as it makes no sense to me.
