I have see quite a few questions placed on hold because they call for answers based on opinions rather than facts.
My question is: is this an appropriate standard for Academia.stackexchange?
I understand and support this standard if the domain were programming (e.g. TEX.stackexchange) or science or history.
In the domain of academia this standard seems very inappropriate. While there are many questions that might be proposed that could be answered by facts (e.g. "What percentage of PhD graduates from non-top-10 Sociology departments get tenure-track jobs within 5 years of graduation?"), the vast majority of questions on academia.stackexchange call for answers based on judgment, which might also include personal opinion.
If answers are based on opinion and also provide justification and explanation, then I believe this will be sufficient to meet the needs of questioners.
Recommendation: I propose that the standard -- "answers should be based on fact rather than opinion" -- be dropped.
