Is it true, that long answers to questions attract more upvotes than shorter precise answers?
I have seen many beautiful short answers, but they are neglected and overshadowed by the longer ones.
I wrote a SEDE query for the task. The results:
What we can see here, is the following:
I think the answer is partially yes, partially not.
More exactly, we have different secondary effects which can increase the score of the answers. All of these are my subjective experience, I don't have SEDE queries to support them (although I could produce some if needed):
Some of these can be considered contraproductive, some of them not.
Many voters don't read through the whole text, but they vote it up if they think it looks well. These secondary effects are mainly about their votes.
All of these secondary effects are overshadowed by the primary effect of the voting score: write good and useful answers. All of the users of the site with the highest reputation are really good in this, and not in (1), (3)-(5).
