[dubious ]

Template documentation [view] [edit] [history] [purge]

Add {{Dubious}} after a specific statement or alleged fact that is sourced but that nevertheless seems dubious or unlikely. Most commonly, this involves uncertainty regarding the veracity or accuracy of the given source, or of an editor's interpretation of that source.


The purposes of this template are:

  • to point out uncertainty over conflicting sources
  • to question the veracity, accuracy, or methodology employed by a given source
  • to express concerns that the source may have been misinterpreted
  • to alert editors that additional sources need to be found, to ascertain the statement's validity

Note: Refer to the Incorrect uses section below for examples of inappropriate uses, and suggested alternatives.


When using this template, it is strongly suggested to simultaneously discuss the dubious statement on the article's talk page – and to point this template to a specific talk page section (either new or existing) which contains that discussion. To do so, use the following syntax:

{{Dubious|Talk section name}}
Note, do not include Talk:PAGE#, just the section title.

Do not add this template to a page more than a reasonable number of times. Please consider using one of the other templates mentioned below instead.


  • |1=Talk section name – the first field should point to the section name on the talk page which contains the discussion.
    • If the section name contains an equal sign, use the following syntax: {{Dubious|1=Does x = 5?}}.
    • Other special characters used in section names (such as brackets, "[" and "]") may need to be escaped. For example, the markup:
{{Dubious|K%5BX%5D is NOT integral}}
would produce:
{{Dubious|K[X] is NOT integral}}.
  • |date= the month and year when the template was added. Example: |date=March 2021.

|reason= is not a parameter of this template, but you may use it to add an invisible, short explanation of the issue. It will only be visible in the coding (e.g. when editing the page). To make the reason visible to all readers use an additional template:

{{Hover title|reason|dubious text in article}}

Incorrect uses

This template is not to be used

  • to directly challenge a sourced statement as being incorrect (with sources to back up your claim). Use {{Disputed-inline}} instead.
  • to flag unsourced statements, unless you think they are incorrect. Use {{Citation needed}} instead.
  • to question the reliability / verifiability of a source. Use {{Unreliable source?}} instead.
  • to request verification whether the source in fact says as the statement claims. Use {{Verify source}} instead.
  • to request that a difficult-to-understand statement be re-written. Use {{Clarify}} instead.

If you believe that a statement is both unverifiable and probably wrong, then you should consider removing it from the article (and perhaps copying it to the talk page with an explanation) instead of tagging it.
