In a recent question, aparente001 suggested me
I wonder if waiting to bestow the green checkmark might encourage a larger variety of answers?
Which is something that I (and you, probably) have wondered in the past too.
There is of course no definitive answer. It may depend on the stack, the users, the amount of questions received per day, the amount of answers the question already has...
Even understanding that the answer might change in the future, I can't resist using aparente001's question to poll the community.
Now lets get something clear. There are many valid reasons why someone would visit a question, see that it has an accepted answer and decide to move forward or invest their time elsewhere (maybe in unanswered questions). Maybe it is more about the number and/or quality of answers, or the question itself (not many of our questions receive multiple answers, after all).
The question is,
does seeing that a question has an accepted answer discourage you to work on providing an additional answer for that question?
Feel free to leave a brief comment next to your vote if you want to be verbose and encourage discussion, like
I know that accepted answers can be changed, so mine could best the existing one and become the accepted answer!
I rather work on an unanswered question than work on a post that has already been explained.
It's so difficult to provide an additional answer when the question already has an answer, much more when it has an accepted answer!
I only provide an answer if I see room for an explanation related to a diferencias-regionales about the place where I live.
