According to When should I delete an answer?, answers that are earnest attempts at an explanation, but that are technically incorrect, should be downvoted but not deleted.
However, the Low Quality review queue does not offer an easy way to do the right thing:
- "Looks OK" is inappropriate: "nothing is wrong" doesn't apply to a wrong answer.
- "Edit" is inappropriate: Any edit that corrects the answer would also radically alter the meaning of the post.
- "Recommend Deletion" is inappropriate since it is an earnest but misguided attempt at an answer.
- "Skip" is, unfortunately, the only way to clear this item from the queue. However, skipping items isn't letting the reviewer be helpful.
Therefore, the Low Quality review queue needs to offer better choices of actions.
