I looked at the data a bit using this SEDE query. There are 704 questions where the accepted answer is outscored by another answer. In 486 questions the difference in score between the accepted answer and the highest scoring answer is at least 3. Of those questions where the accepted answer is outscored, in 28 cases the accepted answer has a negative score. ...


I like the idea of going by score only as for the most part the accepted answer will have the highest score. However there will be times when an answer is accepted because it was what the OP wanted to hear even if it might not be a good answer.


I feel like there should be ('should' is a funny word) a hybrid model here which weights the accepted answer as higher scoring than it's actual votes, but does not automatically pin that response. For the reasons discussed, bias and low quality can appear in both accepted and high-scoring responses. SE's model is a little optimistic about human interaction, ...


I'm not sure that unpinning is really needed here. Answers on politics rarely become "outdated" like they do on SO and the other technical sites, especially not on the same time scales. Yes, there are lots of cases where there are answers with more votes than the accepted answer, but I don't think that's actually evidence of needing unpinning, but ...


This could actually be solved soon as they are looking to unpin the accepted answer and sort by question score as the default which would put a bad accepted answer lower in the ranking. Should accepted answers still be pinned to the top of the list of answers?
