I'm puzzled why sometimes very short answers to story identification questions get upvoted so highly. Sometimes there is only a title - with no justification as to *why* that is the correct answer. This concerns me because I think we ought to *"show our working"*; isn't this a fundamental part of a quality answer?

Examples:

 - [Story ID: Teleporting Castle](http://scifi.stackexchange.com/a/63769/143)
 - [Fantasy movie from 70's, or 80's maybe early 90's](http://scifi.stackexchange.com/a/13652/143)
 - [What is this Disney scifi movie from the late 80s/early 90s?](http://scifi.stackexchange.com/a/2323/143)

For reference / comparison, when I answer one of these questions, I try to answer each of the points in the question:

 - [Help me to find the title of this movie](http://scifi.stackexchange.com/a/12009/143)
 - [Show about a man who is held prisoner in a secret place where very peculiar things happen](http://scifi.stackexchange.com/a/7197/143)
 - [Scifi novel from 90's with AI, robots, and a holodeck-like room](http://scifi.stackexchange.com/a/40178/143)

So my questions are:

 1. Why do some one line story identification answers get so many upvotes?
 2. Do others recognise this as a problem?
 3. How can we solve this? Should we simply be more strategic in our voting?
