Intro
Consider two likely scenarios:
Q: How many grams of $\ce{O2}$ are there in one mole of oxygen gas?
I know that O is 16, so it should be 16 grams, AMIRITE? Please halp ugrant kthxbye
Q: How many grams of $\ce{O2}$ are there in one mole of oxygen gas?
I know that O is 16, so it should be 32 grams, AMIRITE? Please halp ugrant kthxbye
The major difference is that the OP got the answer wrong in the first, and right in the second. In the first case, there is something to be said, and in the second, there isn't. Let's call these questions 'AMIRITE' questions (i.e., 'Am I right' questions).
The Issue
Our current — and certainly future — homework policy requires that at least questions that require some calculations and look like exercises from a textbook demonstrate some minimal effort done by the OP, to ensure the site doesn't become useless in an influx of homework questions by lazy OP's who can't bother to spell correctly.
Too little effort is harmful for the thread; but apparently, too much effort is as well. I've witnessed some questions that provide too much effort.
Take a look back at the second scenario. The answer is a yes, you're right! Is there anything to be said? Is there anything left to be said? Of course not, and seldom I have witnessed answers that do not quite match up to our quality standards and the answerer has tossed the argument I just provided. There's nothing to be said about the question, so the answer, albeit of poor quality, is meant to "close the case".
A similar outcome is a comment pointing out that the OP is right in their thinking, or wrong due to this one-line reason. Again, nothing is left to be said unless we delve into off-topic lands. At the best case scenario, we just end up with another question to throw at the heap of the unanswered.
When there's nothing to add to what the question already offers, there is no way the thread will garner good answers and result in a productive interaction, and one of the main reasons we close questions is to prevent bad answers from being given.
Possible solutions
To prevent such misfires, we can
- Close 'AMIRITE' questions as either homework, or dedicate a new slot to them. They're usually closed cases from the beginning anyway. We're just letting some of the other unanswered questions breathe.
- Officiate self-answers or CW answers to AMIRITE questions. We would either notify the OP, or make a CW answer of our own that includes the answer the OP have provided themselves in the question body, and edit it out. After all, there isn't a need to provide effort in the question if the OP is providing a self-answer.
- Another solution or a combination of the above.
So, what should be done? Let's discuss a policy for these.
