I often ask opinion-based questions on Stack Exchange only to have them downvoted and closed, as I often do not know if a question (and its answers) are opinion-based until they are answered. To prevent this, how can I determine if a question is opinion-based before posting it?

This list is far from exhaustive but I try to avoid asking:

  • why people do things;
  • whether people (including you) should do things;
  • for best practices; and
  • generally for the best anything.

What someone answers in each case is likely to be their opinion.

Asking whether/how something can be done, after showing what I've tried to do to answer my own question, is unlikely to be closed as seeking opinions.
