There are a few answers popping up regularly based on «logic».
The problem is obviously not the logic part, it is that the logic depends on uncited facts. Using logic to follow the consequences of cited facts is perfectly acceptable and necessary.
By this I mean answers that:
- Have little or no sensible references
- When prodded, the author typically replies with "I can't reference anything because it's just «logic»"
Whereas it is always, always the case that the author is just speculating (and not using «logic» in the context of facts).
In practice these answers are based on speculation, circular logic and no-true-Scotsman fallacies (and not pure «logic»):
Q: Will you get shocked by lightning in a car?
A: You are isolated, therefore no.
This kind of answer may be OK on other SE sites, but not here. Here's what's wrong with the answer.
- If you are isolated, then you are safe. This is completely obvious and we have no problem with it.
- But are you isolated? In theory yes, because of the wheels, but does this effectively work in practice? Has anyone actually tried it and published the results? The answer is not even addressing the question in this respect.
The site must get rid of these answers because they are:
- low quality and therefore bad for the site in general and bad for the OP
- mere opinion/speculation and therefore tend to spark useless discussions ("bad subjective")
- not real answers to the question
- broken windows, because they are examples of speculative claims being repeated
- very unlikely to be fixed by anyone because fixing them is equivalent to re-writing new answers (and therefore anyone would probably write a correct separate answer instead)
In many cases it's sufficient to leave a comment, and the author will fix or delete the answers. In some other cases the author refuses to help because they are used to other SE where this style of answers is tolerated.
In most cases, moderators and high rep users are being dragged in pointless discussions in the comments.
What should we do to avoid these problematic bad answers?
