I recently answered Is “US Military Intelligence report EW-Pa 128” real? with some information from a forum post. The evidence wasn't great, and I fully admitted it in the answer. However, given the challenge of proving the non-existence of a document that seemed like it was made up for a fictional narrative, it was the best I could do at the time.
After performing some additional research days later, I have uncovered clear that the document is most likely real (although not to say it's accurate). How should I proceed in this case?
Edit the original answer, completely wiping out the old information and leaving only new infomation
- Pros: only accurate information available, cleans up what turned out to be a bad answer
- Cons: removes the answer that other users upvoted, makes it impossible to see the old answer without going into edit history
- Edit the original answer, leaving the old data but in an "archived" state
- Pros: leaves old information available, still gets good information out there
- Cons: answer becomes a mess
- Delete the original answer and put the new answer in
- Pros: same as first option but also eliminates upvotes
- Cons: same as first option but even harder to see original information
- Leave the original answer and answer again
- Pros: leaves old information available, gets good information out, original answer isn't a mess
- Cons: karma farming
What's the best course of action?
