Question: There have been a lot of one or two line answers (very brief) on the main site. Most of them, almost all of them IMO, only suggest one or two things to do and never explain why they would work. Though, such answers might be correct, but since sometimes they get upvoted and stick around longer, it is projecting an image that such short answers can be posted here.

I don't want to single anyone out, but this is an [example](https://interpersonal.stackexchange.com/a/6122/29). It suggests to do one thing that the OP would do, but there is no explanation about why it would work. [It has been stated](https://interpersonal.meta.stackexchange.com/a/1265/29) that answers here should not be mere suggestions and must explain how and/or why they will work.

Though, we have taken an approach to downvote and comment such answers and it's been doing a nice job. But still, there are more answers like this. And it gets worse when the question gets in HNQ and they start to get more and more upvotes.

On the Workplace SE (though I can't say about other ones), I have seen a lot of one-line answers getting numerous upvotes. And it seems that the similar behavior is now appearing on IPS as well. IIRC, answers on SE should explain why and how.

So, what should be done with such answers? Should we only downvote and comment (or a post notice by moderator) and move on, or we should take stricter action such as deletion?

A related answer has been posted on [Workplace Meta](https://workplace.meta.stackexchange.com/a/4901/65039) as well.

Answer: 
As an alternative to @vylix's answer, I'd offer that *education* through commenting is a better teacher than a simple vote for deletion. [This very thing happened to me](https://interpersonal.stackexchange.com/a/6188/3013) - no comment was offered. Just a down vote and vote for deletion. Fortunately apaul linked to this meta question so I could learn.

Absent constructive feedback users will not get the message that one liners are inappropriate for this SE site.

One line answer: If the answer is simply "Try this: ..." and there is no "irrefutable source" (Example: [Help Center > Answering](https://interpersonal.stackexchange.com/help/how-to-answer)) then we run the risk of going against [the purpose of the Stack Exchange sites](https://stackexchange.com/tour).

It **is** possible for a one-liner to be OK, just make certain that it is.

Would my answer better convince you if I continue writing, adding several more paragraphs.

Some things are simple, and so is the solution. Some things are complex, and require establishing a specific set of conditions (or assumptions) under which the provided answer would apply.

Specific examples from the Tour which explain the goals of StackExchange:

* We build libraries of high-quality questions and answers, focused on each community's area of expertise.
* Ask questions, get answers, no distractions.
* This site is all about getting answers. It's not a discussion forum. There's no chit-chat.
* Good answers are voted up and rise to the top. The best answers show up first so that they are always easy to find.
* Our goal is to have the best answers to every question, so if you see questions or answers that can be improved, you can edit them.
* Use comments to ask for more information or clarify a question or answer.

As one can see the Tour page is rich with helpful advice. 

If there are suggestions for improvement of the Tour page they can be put forward by 'asking a question' (even if it's more of a "suggestion" than a "question") on the Meta (you are here) of the site in question.
