Sometimes I have a question and have an idea how to answer it. I'm pretty sure (see edit 1) the idea is correct but not so sure (see edit 1). However, I do want to be so sure (see edit 1), so I ask online. When there are no answers even after a bounty, may I just transfer my idea from the post to an answer? Of course the answer is not necessarily correct, but I think it's a good way to attract attention ASSUMING it's not against the rules. (Of course there's always going to overflow.)
One thing to note is that if I delete the idea from the question post instead of just copying the idea to answer, then question post becomes shorter and therefore hopefully gives more incentive to answer (or comment on my answer).
Edit 1: Sureness is relative. This is of course the whole idea of hypothesis testing in statistics. How sure must I be to answer my own question in this regard? 95%? 99%?
Edit 2: Thank you just_floating for introducing me to this term: Cunningham's Law.
Edit 3: Jonas Meyer says
If you have worked out an answer to your question, you can also post it as an answer. If you're not yet sure it's correct, you could start with a disclaimer to that effect, and ask for feedback.
Edit 4: Does it make any difference if I do community wiki?
