@AndreiROM's (very valid) discussion about the scope issue on this question, How would be our society if it was populated by anthropomorphic dogs?, and my past experience with a different question gives rise to a different issue.
Say that you have a number of questions about a specific topic (@Chaotic's linked question works as well as an example as any). Picking a specific aspect about the broader topic often narrows down the scope to an acceptable question. However this causes an issue when the smaller scoped questions affect one another.
The asker gets a well-researched answer about their more narrowed-scoped question, selects it as the reality in his or her world, and moves on to the next question, posted separately. Since these aspects affect one another, the asker includes either a brief summary (most likely to be read) or a link to his or her previous question (most complete, but is skipped in my experience), and says that such is fact in his or her world.
The responders to the next question very likely have an issue with the previous answer. Maybe it seems illogical, unreasonable, or scientifically impossible as best as they understand. The responders are forced to:
- Not respond to the second quesiton at all, possibly resurrecting the first question with a new answer in lieu of answering the second
- Get off topic in their reply to the second question and address an erroneous assumption established by the first question
- Provide an answer that they genuinely believe founded on an incorrection or dysfunctional assumption
...For technical sites with far more concrete answers such as Stack Overflow this doesn't become an issue, but on World Building, where almost every answer is inevitably tied to opinion (at worse) and judgment calls and/or armchair engineering (at best), this seems to break down. Even more when these questions become something of a chain.
Given these issues, what is the best way to handle these situations?
Note: I can provide a theoretical example if needed to offer something more concrete to discuss.
