We have had a number of edits recently that just put Wikipedia links on phrases, in posts that the editor was not the author of. Is this a desirable practice?

For example, in https://crypto.stackexchange.com/review/suggested-edits/42748, the question was about oblivious transfer in electronic voting protocols.

  • The Wikipedia article on oblivious transfer does not mention electronic voting protocols, but the question is about how oblivious transfer is used in them, suggesting the author had a reference in mind that does connect the two.

  • The Wikipedia article on e-voting does not discuss cryptography protocols; it is about the broader sociopolitical context of electronic voting systems, and only briefly mentions cryptography in passing.

Often, a reader who is asking about terminology has found it used in a particular source—such as a textbook or conference paper or journal article, not Wikipedia.

Is it helpful and appropriate to put links to Wikipedia pages that do not discuss the subject under question and that may have no connection to the source a reader was asking about?

Sure, if the links are relevant. Stack Exchange is a collaborative platform. Editing other people's posts to improve them is encouraged.

Quoting the official guidelines on editing:

When should I edit posts?

Any time you see a post that needs improvement and are inclined to suggest an edit, you are welcome to do so. (…) Common reasons for edits include: (…)

  • To add related resources or hyperlinks

If adding a link to Wikipedia improves the post, accept the edit. If the link is wrong or irrelevant, reject the edit. Generally, linking to Wikipedia or some other reference is a good idea in two cases:

  • For explanation, when mentioning concepts that are likely to be obvious to some readers, but mysterious to others. (Concepts that most readers are unlikely to understand should be explained in the post, and concepts that most readers would find obvious don't need any explanation.)
  • For further information, when mentioning a concept that is peripheral to the post, which doesn't warrant further discussion inside the post but where a curious reader might want to know more.

If the Wikipedia article is relevant but unhelpful or misleading, that's a reason to lead towards rejection. However, the best outcome would be to go and improve the article!

Do not reject a suggested edit or roll back an edit on principle because “it modifies the post”. Edits modify the post by definition. Reviewing suggested edits is a judgement call, that's why we have humans doing it and not computers. But as a human, you're supposed to apply common sense and follow shared values. Stack Exchange has very few firm rules but many guidelines, and for editing in particular there are official guidelines. You should go against the guidelines if a specific case would go against our goal of “build[ing] a library of detailed answers to every question about cryptography and cryptanalysis”. But if you're systematically going against the guidelines, you're doing it wrong.

Different people can have different thresholds for when a suggested edit is acceptable and when it does too much, and that's fine. But if you systematically apply your own rules that go against the guidelines, that's not fine. It disturbs me to see moderators here who completely ignore the official guidelines and make recommendations that go completely against them, given that the job of moderators includes enforcing these rules.

    $\begingroup$ It's one thing to provide a bibliographic reference to a particular paper that the author of a post was referring to. It's quite another to blindly put a link to Wikipedia on some phrase without independently verifying that the Wikipedia article is a coherent reference on the subject, and provides the definition and explanatory context that the author meant—which can really be assessed only when the editor and reviewer are particularly familiar with the term in question as it is used and confident in what the author was asking. $\endgroup$ Sep 23, 2019 at 20:13
  • $\begingroup$ @SqueamishOssifrage In point of fact, editing is a dialectical process between writer and editor. The discussion is best done face-to-face, and it usually takes at least two iterations. As far as this website goes, we do our best. Your question and response have helped raise the bar of the editing work on this website. $\endgroup$

  • $\begingroup$ I don't know what you mean with "cricket" but yes, we were probably out of bounds w.r.t. the rules, and the constructive part of your answer was never questioned. I've also removed that the last comment; let's leave it at this. $\endgroup$

No. This is not desirable because it does not necessarily reflect the author's intent, and Wikipedia is a notoriously bad reference on cryptography so it is likely to be misleading at best and change the author's meaning at worst. If the author wants to cite the definition that is currently on Wikipedia, they can do so themselves.

  • $\begingroup$ The questioner is right because Wikipedia is often unreliable. $\endgroup$

Yes it's a desirable practice and we should allow it

  • $\begingroup$ @kelalaka Sure, but how do we define when it is ok to insert a link? Should the first occurrence of any given term on every question/answer be a link? That clearly seems like it goes too far to me. But if not every Q/A, then which ones, and why? $\endgroup$

  • $\begingroup$ @SqueamishOssifrage well, maybe a mod can decide that this question has a broad audience so inserting a link to Wikipedia is helpful. This time we put the burden on mods to check that the Wikipedia article is good. IMHO, during the active time of the question is should be handled by anybody interested in the question, not later so that the OP can argue, too. $\endgroup$

No, this is not desirable.

Why not?

But the reason is not because of the quality of content on wikipedia, it's that edits should be restricted to typographical fixes

There is an exception: removal of thank-yous, signatures, taglines, etc is encouraged.

An edit that modifies the content/subject matter of a question or answer is in general inappropriate.

Editing a link into a question can imply to future readers that the question asker is familiar with the linked content, and that their question is the result of their reading of that content.

If an answer to a particular question should really contain of links to certain resources, then post those links as your own answer (along with an explanation/summary) rather than editing them into someone else's answer.

    $\begingroup$ I think saying "typographical fixes" (which just means fixing miss-spellings and punctuation?) is a bit too restricting here, as we also commonly improve formatting and style / readability of posts. $\endgroup$

    $\begingroup$ Formatting style is part of typography. Typography is not just the study of typos. For example, converting between typewriter math and $\mathrm\TeX$ and fixing markdown is typographical. $\endgroup$ Sep 15, 2019 at 22:19
