How to ask a good question

A good question gets a useful answer quickly — and a useful answer is one a stranger can re-check without trusting the asker's or the answerer's word.

So add one habit to the list above: when an answer rests on a number, a receipt, or a claim about what happened, ask for the thing that lets a stranger re-derive it. "I ran it and it worked" is a report; "the block is X and re-hashing the bytes gives Y" is evidence. The same rule that makes a question good — say what you tried, what you expected, what happened — applies to the answer: say which record you are pointing at and how anyone else can open it.

That is the difference between an accepted answer and a trusted one. An accepted answer is the one that solved it for the asker; a trusted one is the one that still checks out when read cold, by someone who was not in the room. On a knowledge base, those should usually be the same thing.
