I have noticed that well-sourced and good questions get fewer votes compared to some "interesting" ones. For example, a one-liner question gets ~300 votes (the maximum number of upvotes for a question on this site) without the OP doing any efforts to research or even type the same thing on google (direct answers for this are available with just one search). It is, however, an interesting question, which is the reason for the upvotes.
Now there are posts with a good reference and source, but with < 5 upvotes. This one, for example. has only 3.
So, the question is, can we do something to encourage good questions with reliable sources? It feels unfair to see a one-line question with no source get appreciated while good questions with some effort on research get ignored.
