One of the next most popular Risk Factor suggestions is Multiple Questions so this is a general discussion of that close reason.
The main point to clarify is:
- Should questions be off topic for this reason
- If so should it be a close reason or a "canned comment".
Risk Factor: Multiple Questions in One
You are asking multiple questions in one question.
Asking multiple questions in one is not recommended as it makes it hard to answer with a concise and focused reply. Additionally it becomes much harder to rate answers as to whether one is better than another as the "best" answer to each part of your question may be held in different answers.
How to Fix:
Separate your question into multiple questions. In general we recommend asking one question first and then writing follow on questions based on the answers to that (feel free to link from one question to another) but if the answers really do not depend on each other then you are welcome to ask multiple questions at once.
A common format we see if an introduction to the world followed by a list of multiple questions about that world. Make sure you look at each of those questions and consider whether it is substantial enough to have a good answer written about that alone. If so break it out into a separate question, ideally linked back to the first one.
Discussion points so far:
I agree that too many question in one post is a problem, but it doesn't need a custom close reason -- that's what "too broad" is for. However, something to link to that explains how to fix it (like this does) would be good.
By creating a specific close reason we can have it link to a question on how to fix it and also make it explicitly clear to the person who's being closed why it's been closed and what the need to do to fix it. I think this is specific enough to warrant being a special case - however I do agree that if we have too many other custom close reasons this is one that could be cut.
This could also be done via a comment linking to the meta post.
The subject matter of this site calls for some leeway on the multiple question front. For instance, I might concisely ask "how would people live in 10% gravity?". Or I might expand on that and ask for examples with respect to biology, performing common tasks like cooking and showering, required exercise routines and supporting technology, and so on. All of those are implicitly invited in the concise version (and having a new question for each one isn't useful), so explicitly requesting them should be valid. Not valid would be "how would people live in 10% gravity and with 16 hour days". – aroth yesterday
That's a great example of what should be closed for this reason. Imagine if you got 3 answers. One was perfect for cooking but bad for showering. One had a great description of the exercise but nothing else, another one had good answers on both cooking and showering but was completely wrong on the biology. How would you vote for or rate those answers against each other and which one would you accept? The correct way is to ask multiple questions where each answer can address one specific area and focus on and be a great answer to that area.
