This template is intended to be stronger than {{request quote}} or {{verify source}}. The intended use is when a plausible source has been provided, but an editor has thoroughly checked that source and found that it does not support the text of the article. Robert A.West (Talk) 21:38, 11 July 2006 (UTC)[reply]

The citation should just be removed and replaced with {{fact}}. This tag seems redundant. – Þ  06:55, 17 March 2007 (UTC)[reply]

Then the mis-citing editor will simply put back the original bogus source. — SMcCandlish [talk] [contrib] ツ 16:20, 17 March 2007 (UTC) [Corrected 00:01, 19 March 2007 (UTC)][reply]

The mis-citing editor you mean? Such cases should go to talk. If the original editor continually reverts, take it to dispute resolution. Special:Whatlinkshere/Template:Failed verification reveals only 68 links, many of which are not in mainspace articles. It would seem this might be a good candidate for TfD. – Þ  20:40, 18 March 2007 (UTC)[reply]

Right, that was a typo. Anyway, I don't disagree with your take on what process should be. I'm simply countering the idea that the proper response is deleting instead of discussion. I.e., what's good for the gander is good for the goose in this case. The point of the template is to generate discussion as to how to fix something. — SMcCandlish [talk] [contrib] ツ 00:01, 19 March 2007 (UTC)[reply]

Is it an appropriate use of the tag to indicate that a link that has been given is now broken? It seems that does not fall under the instructions for its use; surely there is a difference between giving a citation that doesn't include what it is purported to and the url ceasing to exist and therefore being unverifiable?70.131.255.105 (talk) 22:24, 29 December 2007 (UTC)[reply]

Should {{Failed verification}} be used inside or outside the ref? Inside puts the message next to the citation and outside puts in the body of the article. ~

I would say outside. It is important enough to cast doubt on the statement the citation claims to support. For many readers (myself included) merely seeing the footnote link provides some support for the statement. Rich Farmbrough, 07:58, 9 April 2010 (UTC).[reply]

Does anyone have a problem with renaming the template to {{Not in citation}}? Its current title and all other redirects to it would continue to work transparently as synonyms. We could go with {{Not in citation given}}, too, but I think the shorter form has the best combination of memorability and brevity.--Father Goose (talk) 08:14, 24 February 2010 (UTC)[reply]

Second that. "Not in citation" is more succinct than the current title. Gun Powder Ma (talk) 23:06, 4 April 2010 (UTC)[reply]

So, no objections? If not, I'll move it next time I swing back this way.--Father Goose (talk) 02:29, 9 April 2010 (UTC)[reply]

This template would be more useful if it could link to section of the talk page where the failed verification is discussed. This feature is in some other inline templates so it shouldn't be too hard to implement. Thanks, SteveMcCluskey (talk) 21:22, 4 April 2010 (UTC)[reply]

I second that, there are many cases where such a link would be most useful. Could you please implement such a feature? Gun Powder Ma (talk) 23:04, 4 April 2010 (UTC)[reply]

Done. Rich Farmbrough, 07:55, 9 April 2010 (UTC).[reply]

A source is cited which is a top list that updates every week. Therefore there is no way to verify the source, since the data now is different. Wayback Machine does not happen to have the exact week the source is referring to. Is this the right tag for this or should something else be used? --Muhandes (talk) 07:24, 1 July 2010 (UTC)[reply]

According to the documentation, this tag should only be used if "the source says something other than what is contained in the article." "For example, if the article says that 26% of statistics are made up, and the source says that 32% of statistics are made up, then that information has failed verification." In other words, this seems to say the tag should be used when the source given contradicts the statement. However, the tag's text simply says "not in citation given".

Should the text be changed to, say, "contradicted by citation", or should the documentation be changed to say the source simply needs to not support the statement, rather contradict it? --Chealer (talk) 16:53, 22 March 2012 (UTC)[reply]

"Does not support". When a reliable source blatantly contradicts the text in the article, the article text has to change, per WP:V, unless two sources contradict each other, in which case it's time for {{disputed-inline}}, a talk page discussion and more sourcing. — SMcCandlish   Talk⇒ ɖ∘¿¤þ   Contrib. 02:03, 23 March 2012 (UTC)[reply]

This template is particularly useful when the statement is missing from the source as well as when it contradicts it. Using the above example, the article says 26% of statistics are made up but the source doesn't give any percentage. This is also failed verification, but there's no contradiction in this case. D O N D E groovily Talk to me 12:42, 24 March 2012 (UTC)[reply]

Thank you both. So, is there any opposition to changing point 3 from "the source says something other than what is contained in the article" to "the source does not support what is contained in the article"? --Chealer (talk) 05:07, 11 April 2012 (UTC)[reply]

 Done I think we could also add an indication that if the problematic reference is the only one given to support a statement, {{fact}} should also be added. Unless someone has a better idea of what to do in these cases. --Chealer (talk) 03:09, 17 April 2012 (UTC)[reply]

Clarification on when to use[edit]

I changed the documentation page to clarify when to use it. In short, this template should not be used if the source has no relevance to the topic. In such cases, the references should simply be deleted. D O N D E groovily Talk to me 12:40, 24 March 2012 (UTC)[reply]

That helped a little, but the percentage example isn't helpful. This template is most often used for "judgement call" matters, in which an editor is seemingly engaging in novel synthesis or questionable interpretation of a source, not misquoting statistics. If a percentage were misquoted, it would simply be fixed, not flagged with this template. We need a better example. — SMcCandlish   Talk⇒ ɖ∘¿¤þ   Contrib. 22:48, 24 March 2012 (UTC)[reply]

Is this template meant to be nested within the ref tag, or left in the text at the ref marker?  -- WikHead (talk) 12:02, 29 May 2012 (UTC)[reply]

Oops - never mind. I see this has already been asked and answered above at #Inside or outside the ref?  -- WikHead (talk) 12:11, 29 May 2012 (UTC)[reply]

What is the utility of a tag like this? All content on Wikipedia must be verifiable. If it is found to be unverifiable, or if content has failed verification, shouldn't it simply be removed? We may as well have a template marking patently false information or content which is obviously vandalism. The policy there is to remove or revert on sight, why not here? MMartyniuk (talk) 13:03, 18 July 2012 (UTC)[reply]

This tag is added to a specific statement, references by a specific source. It may well be that other sources are available. The template doesn't say that the statement is impossible to verify, just that a specific attempt at verification has failed. Debresser (talk) 13:50, 18 July 2012 (UTC)[reply]

Which leaves the statement unverified. Should we really keep unverified information on Wikipedia indefinitely on the off chance that somebody will be able to verify it in the future? I thought the onus was on the person making the claim to support it with a citation, not to make a claim with a false citation and let other do the research. At the very least, shouldn't failed verification claims be outcommented until they are verified?

Wikipedia:Verifiability currently states "No matter how convinced you are that something is true, do not add it to an article unless it is verifiable" and "The burden of evidence lies with the editor who adds or restores material." MMartyniuk (talk) 14:09, 18 July 2012 (UTC)[reply]

Again: the fact that a statement is unverified is not yet reason to remove it. If it were unverifiable, that would be reason to remove it. That is why we have {{Citation needed}} and all those other tags. Debresser (talk) 15:05, 18 July 2012 (UTC)[reply]

All the same, there ought to be a policy that text tagged with ^{[citation needed]} or ^{[not in citation given]} should not stay on Wikipedia indefinitely. An editor applying such a tag has a responsibility to take further action if there is no response within a reasonable time. The Watcher count helps indicate how long a wait is reasonable, but a month is surely the outer limit. (No, I did not use the templates in producing this comment.) Peter M. Brown (talk) 15:30, 18 July 2012 (UTC)[reply]

Sometimes statements remain unsourced for years. And I fail to see the big problem. If a statement is not contested, let it be. Debresser (talk) 16:30, 18 July 2012 (UTC)[reply]

I have no problem with an uncontested statement being unsourced indefinitely. A challenge is frivolous, however, if the challenger fails to follow up when the challenge is not met. Most of these tags that clutter up Wikipedia are a distraction for the general reader and are quite pointless. Peter M. Brown (talk) 16:44, 18 July 2012 (UTC)[reply]

They're not even slightly pointless; they alert readers to information that may not be reliable at all. In this template's particular case, they even more importantly flag material that isn't just unverified but for which verification attempts have failed. Yes, it should not be used long-term in any particular instance. It's an invitation to people who are certain the information is correct to quickly provide the/a correct source for it. The most common cause of its use is when facts are ascribed to the wrong sources (e.g. because of interpolation of unsourced facts between two sourced ones that share a source, or moving sourced facts, without their citation, to another passage sourced to a difference source), and the second is when a source has been misinterpreted and the source does not actually support the fact being claimed.  — SMcCandlish ☺ ☏ ¢ ≽^ʌⱷ҅_ᴥⱷ^ʌ≼  03:10, 2 August 2014 (UTC)[reply]

 – Done to the extent possible without a site-wide consensus discussion about how this whole class of templates behaves.

Any chance a "Reason" category can be added to this template? It would be useful if a "Reason" category could be included, with the "reason" displayed when hovering the cursor over the tag. I guess this could be considered a request... FWIW. --IJBall (talk) 20:07, 27 July 2014 (UTC)[reply]

I think you mean a template parameter, not a WP:Category, and have changed the topic heading to reflect this. Virtually all inline templates of this sort support a |reason=Your text here parameter, it simply doesn't display in the article, and is a note for editors, in the wikicode. I've updated this template's documentation to illustrate how to use this. To change this behavior in these templates, to display in the article on mouse-over or some other event would be a bigger discussion than a change request here, e.g. maybe a WP:RFC opened at Wikipedia talk:WikiProject Inline Templates.  — SMcCandlish ☺ ☏ ¢ ≽^ʌⱷ҅_ᴥⱷ^ʌ≼  03:04, 2 August 2014 (UTC)[reply]

OK, thanks. (And thanks for correcting me!) --IJBall (talk) 04:52, 2 August 2014 (UTC)[reply]

These statements/references seem to me worthy of more attention than {{Citation needed}} tagged statements. There are currently 4,686 pages transcluding of this template compared with something over 344,479 members of the category tree rooted at Category:Articles with unsourced statements. I propose moving these 4,686 to Category:Articles with failed verification. I will try to cut the code in a few days if there is no objection the move. All the best: Rich Farmbrough, 20:11, 22 August 2014 (UTC).

Code in sandbox. I will make this live presently. Please feel free to raise issues, or request a revert if there are any problems. All the best: Rich Farmbrough, 18:05, 25 November 2014 (UTC).

Category:Articles that have failed verification? Category:Articles that fail verification? Even better would be a title that doesn't include 'Article' because categories contain articles; no need to state to obvious. Categories can also contain Files which are not articles but might contain this template. Perhaps Category:Claims that fail verification or Category:Statements that fail verification, or something similar.

—Trappist the monk (talk) 18:33, 25 November 2014 (UTC)[reply]

It is fairly standard to use "Articles" because we want to distinguish from content categories. "Articles with claims that have failed verification" might be better, in terms of precision, but it is overly long. A Merry Christmas! Rich Farmbrough, 02:15, 23 December 2014 (UTC).

@SMcCandlish: When using the "reason" parameter with double quote marks, then it doesn't properly reflect in the tooltip. For example:

{{Failed verification|reason=Source does not mention "foo bar"}} produces: ^{[failed verification]}

HTML:

<span title="&quot;Source">not in citation given</span>

-- intgr [talk] 11:39, 20 July 2017 (UTC)[reply]

Can use " instead of ". --Obsuser (talk) 03:47, 23 July 2017 (UTC)[reply]

Yeah, this is a limitation of HTML itself; the double-quote character has to be escaped, and we can't use any markup like italics.  — SMcCandlish ☺ ☏ ¢ ≽^ʌⱷ҅_ᴥⱷ^ʌ≼  01:04, 28 July 2017 (UTC)[reply]

I updated the documentation, which was wrong about this parameter anyway (some time between the original 2014 discussion about it and now, someone implemented it as a tooltip – maybe even me – without updating the docs).  — SMcCandlish ☺ ☏ ¢ ≽^ʌⱷ҅_ᴥⱷ^ʌ≼  01:08, 28 July 2017 (UTC)[reply]

Currently the text says "not in citation given". It is better if it is just "failed verification". As in so many cases in the past with inline-tags, people keep "improving" the text until it means something semantically different than the name of the template. A source "failing verification" does not imply the information is not in the source, which is a stronger claim. It simply means somebody was unable to verify the information. It may (or even likely) means it is not in the source but there's a chance the person was simply unable to find it. For instance, what brought me here was a reference to a book that had no page or chapter information to help locate the spot that supports the article text the source is supposed to support. That reference should be flagged but I don't wish to make the claim that the information is not in the source when it may be that I just overlooked it. There are two ways to fix this, the text could be "failed verification" or perhaps "not in citation given?" (note the question mark). I am a FIRM believer in keeping with the programming mantra of the Principle of least astonishment, so "failed verification" seems clearly the best option to me. Jason Quinn (talk) 21:44, 22 June 2019 (UTC)[reply]

For the case you describe where pagination has been omitted, perhaps {{page needed}}?

Your assertion that people keep "improving" the text until it means something semantically different doesn't appear to be true for this template. A quick scan of the template's history would seem to indicate that the basic rendering has not much changed since the template's creation.

This is not to say that I disagree with what I think is your main point: that {{failed verification}} should render as: ^{[failed verification]}

Intend to change text to "failed verification"[edit]

Nearly a month has passed for discussion. I intend to make the change to "failed verification" I suggested above unless anybody wishes to discuss it more. Jason Quinn (talk) 20:14, 4 July 2019 (UTC)[reply]

 Done. Jason Quinn (talk) 19:21, 9 July 2019 (UTC)[reply]

I urge you to revert this change. "Not in citation given" was a clear English statement. "Failed verification" conveys only a vague meaning. It's also off-putting to users. Does Wikipedia have an AI which is verifying claims? Also, as you say, "not in citation given" is a stronger statement. Since it's by far the most common case, a stronger statement is better. The stated motivation for the change was that the wording wasn't correct when a page or chapter is needed, but per the response there's another template for this, so I don't see any benefit to offset the drawbacks. Regards, Dan Bloch (talk) 17:05, 12 July 2019 (UTC)[reply]

One possibility is that we could make {{Not in citation given}}, which is currently a redirect here, the main template if we want to use "Not in citation given" as the text. Another is that they are split into two different templates. Jason Quinn (talk) 12:16, 13 July 2019 (UTC)[reply]

I'd be happy with either of these changes. I'm not in the template editors group so I can't make changes myself. Dan Bloch (talk) 18:42, 13 July 2019 (UTC)[reply]

Yes, splitting these two would be great! The use cases for these two is similar, but not identical. In addition to pointing out unverified info, "not in citation given" can point out that 1. the source cited is completely irrelevant to the preceding sentence and 2. that a particular snippet of text isn't mentioned in the next citation and that you've checked it. "Failed verification" to me means more "not in this source and I've also Googled it but couldn't verify". The overlap is large, but I'd like to see those two split.

This template shouldn't exist at all in an encyclopedia. If a claim is not verified in the source given, then it should be removed. Azerty82 (talk)

Remove the punctuation around "(See discussion.)", make the S lowercase, and use instead a spaced en dash ( – ) to separate it from the phrase "failed verification". (This should be done for both instances of "(See discussion.)")

This is to change ^{[failed verification (See discussion.)]} to the more typographically consistent ^{[failed verification – see discussion]} when either the talk or talkpage parameter is provided. — Ardub23 (talk) 19:20, 15 June 2020 (UTC)[reply]
