Template:Self-contradictory/sandbox

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

This template will categorize tagged articles into Category:Self-contradictory articles.

• This template is a self-reference.
• This template is not useful for substitution.

After posting this template

Please start a section on the article's talk page to discuss and specify the specific section that contradicts itself. The third optional parameter is the name of a specific section on the specified talk page.

It is possible to specify the subject about which the article or section is contradictory with the optional parameter about.

Example of use

{{Self-contradictory|about=the cause of death|date=May 2025}}

This renders as:

Adding the optional text |section or |article changes the vague default wording to be more specific:

• Default: "This article or section appears to contradict ..." followed by "itself" or a link to an article named with |article=
• |article or |1=article – "This article appears to contradict ..." followed by "itself" or a link to an article named with |article=
• |section or |1=section – "This section appears to contradict ..." followed by "itself" or a link to an article named with |article=
• |othersection or |1=othersection – "This section appears to contradict another section of this article" (this parameter is ignored if mutually exclusive parameter |article= has a value; the default output will result).

More complex examples of use

{{Self-contradictory|section|date=May 2025}}

{{Self-contradictory|about=the cause of death|1=article|date=May 2025}}

{{Self-contradictory|othersection|date=May 2025}}

{{Self-contradictory|section|article=John F. Kennedy|about=the cause of death|date=May 2025}}

Notes:

• The date-substitution template may be used to automatically generate the date, e.g., {{Self-contradictory|{{subst:DATE}}}}. See Help:Substitution for more information.
• The |date= parameter need not be added by the editor: if not entered, a bot will soon add it. The date parameter consists of the full English name of the current month with initial capital, a space, and the year, not full dates, ISO date order, or other formatting; e.g., "January 2013", but not "jan13" or "7 January 2013" or "2013-01". Any deviation from this rule will result in an "invalid date parameter" error.
