Similar to this question: The Issue with Multiple Answers, but instead of cherry-picking parts of the answers you agree/disagree with, I'm asking about an answer that is basically a kitchen sink list of short unrelated answers. I hunted the meta-discussions and the FAQ, but the related topics I found tend to blame the question as "too broad". However there seems to be a consensus that unrelated answers should be separate answers, and that short one-sentence answers are not proper answers.
An example kitchen sink list answer to the question "How to explain human life expectancy increase?" is here, which includes curing 3 separate and unrelated chronic diseases: cancer, Alzhiemer's, and heart disease, discovering a new energy source, ending famine and war, solving air pollution, and discovering a cure for aging. As worded, only one of the co-answers progress logically (a new energy source leads to less air pollution), and a few progress at least tenuously (energy source leads to end of famine and war, although that could be debated), but curing all top chronic diseases and another unrelated medical breakthrough – none of which are more than a single sentence – seems to render community voting almost irrelevant. One answer to a related meta-discussion suggests upvoting if you like SOME of the answer, hence a kitchen sink list may be a strategy to gain votes (my example is the most upvoted answer for that question by a large margin).
When I commented that the answer seemed "too broad", I was accused by the author of plagiarizing an item from his list! As I recall, my answer actually took time to write since I was attempting to follow the guidelines with helpful info and link, but had I dashed off a simple sentence with little or no explanation my entry might have been posted first too. Clearly my comment made the author feel threatened and wasn't seen as constructive. Rather than indulge a flame war I post it here.
I don't see WB as a competition for "first answer with the most options", so this insult just made me laugh, but this issue is not specifically covered in the FAQ. It may be a downside of the point-scoring system – the "quantity" of a kitchen sink list might seem better than a detailed "quality" answer, but it's inconsistent with the way questions are judged, and it doesn't seem to be compatible with most of the official statements about what makes a proper answer.
I leave it for you to consider, as my involvement here has waned and I find I am not as invested as I once was, partly due to the odd ego-wrangling and somewhat arbitrary point system that imho creates an artificial "score" that becomes its own goal.
