Sometimes, the content of a question may change.

For example, an author of a general question (old_question_1) precises the topic of a question (new_question_1) and at the same time starts an another question (question_2), which is a special case of the old_question_1.

What has the answerer of the old_question_1 to do, when his answer doesn't anymore fit to the new_question_1 but to the question_2? Do the answerer should make a copy of his answer in the question_2 thread and delete the answer in the thread of new_qustion_1 or are there better alternatives?

  • In an ideal world, this should not happen. Specially editors should try hard to preserve the meaning that the original poster (OP) of the question had intended. Unfortunately, it can happen that the OP learns that E wanted to ask something different and changes Eir question. Aug 30 '16 at 16:28

Questions should not change their meaning when there are already answers, or those answers would be invalidated.

If a user asked a question, edited it after it was answered, and asked another question for which the answers are a subset of the answers for the first question, I would:

  • Revert the first question to the previous reversion
  • Closed the second question as duplicate of the first question

Then, it depends from what exactly the questions ask. For sure, I would revert the question change done after it was answered, if the change modifies its meaning.
