{{nutshell|Administrators may take action against [[Wikipedia:Sockpuppetry|sock puppetry]] or [[Wikipedia:Sockpuppetry#Meatpuppetry|meat puppetry]] if there are obvious correlations in behavior.}}&lt;br /&gt;
[[File:Wood duck eclipse.jpg|thumb|alt=A photograph of a wood duck standing on a rock.|&amp;quot;Well, it &amp;#039;&amp;#039;could&amp;#039;&amp;#039; be a [[Rabbit–duck illusion|rabbit in disguise]]...&amp;quot; (but it isn&amp;#039;t)]]&lt;br /&gt;
&lt;br /&gt;
The [[duck test]]&amp;amp;nbsp;– &amp;quot;If it looks like a duck, swims like a duck, and quacks like a duck, then [[Operational definition|it probably is a duck]]&amp;quot;&amp;amp;nbsp;– suggests that something can be identified by its habitual characteristics.&lt;br /&gt;
&lt;br /&gt;
The duck test does not apply to non-obvious cases. Unless there is evidence which proves otherwise beyond a reasonable doubt, editors must [[Wikipedia:Assume good faith|assume good faith]] from others.&lt;br /&gt;
&lt;br /&gt;
== Usage ==&lt;br /&gt;
The &amp;quot;duck test&amp;quot; is meant to be used for internal processes within Wikipedia. For example, consider that &amp;quot;[[User:Example1]]&amp;quot; is engaged in a [[WP:DISPUTE|heated dispute]] with someone else, and gets blocked because of it. Immediately after, a &amp;quot;[[User:Example2]]&amp;quot; registers on Wikipedia and continues the dispute right away, saying the same things and in the same tone. The duck test allows us to consider it &amp;#039;&amp;#039;&amp;#039;an obvious [[WP:BADSOCK|sock-puppet]]&amp;#039;&amp;#039;&amp;#039;, and act in consequence. If &amp;quot;[[User:Example3]]&amp;quot; then registers and continues the dispute, it is appropriate to escalate sanctions, because the matching behaviour is sufficiently obvious to deal with it as sock-puppetry again.&lt;br /&gt;
&lt;br /&gt;
(However, check Example1 and Example2 aren&amp;#039;t longstanding editors with similar names - [[WP:CONFUSED|it does happen]]).&lt;br /&gt;
&lt;br /&gt;
==Variations==&lt;br /&gt;
[[File:Sockenpuppentanz2.jpg|thumb|alt=A number of literal sock puppets with buttons for eyes. One wears a pair of glasses. Another has yarn for hair.|If your favourite [[YouTuber]]&amp;#039;s article gets [[WP:AfD|nominated for deletion]], &amp;#039;&amp;#039;don&amp;#039;t&amp;#039;&amp;#039; get all your [[WP:Meatpuppetry|friends]] to say &amp;quot;[[WP:ILIKEIT|I like it!]]&amp;quot; Even though they all &amp;#039;&amp;#039;look&amp;#039;&amp;#039; different, we can spot that you recruited them...]]&lt;br /&gt;
A variation of the duck test in conversations can be found in community discussions where consensus is required, most obviously [[WP:AFD|Articles for deletion]]. If &amp;#039;&amp;#039;&amp;#039;consensus appears to be approaching&amp;#039;&amp;#039;&amp;#039; one direction, aside from a handful of accounts that are using the same [[WP:ATA|bad arguments]] (often &amp;quot;[[WP:ILIKEIT|I like it]]&amp;quot; or &amp;quot;[[WP:JNN|It&amp;#039;s just not notable]]&amp;quot;), it might be reasonable to conclude that, even if direct sockpuppetry is not occurring, the accounts may have still [[WP:MEAT|ganged up together]].&lt;br /&gt;
&lt;br /&gt;
The duck test may also &amp;#039;&amp;#039;&amp;#039;apply to [[WP:COPYVIO|copyright violations]]&amp;#039;&amp;#039;&amp;#039;. If there is an image that is clearly a movie or TV screenshot, or magazine or CD cover, licensed as an own work by the author, the duck test would allow us to treat it as a copyright violation, even if the specific source of the image remains unknown. For example, &amp;#039;&amp;#039;theoretically&amp;#039;&amp;#039; the actual owner of the movie/CD/whatever copyright &amp;#039;&amp;#039;might&amp;#039;&amp;#039; be re-licensing the image [[GFDL]] and [[CC-BY-SA]] to Wikipedia ... but the image should be [[WP:F9|speedily deleted as a copyright violation]] despite this slim possibility, because there is no need to prove [[beyond a reasonable doubt]] that the uploader was &amp;#039;&amp;#039;not&amp;#039;&amp;#039; in fact the copyright holder ... if so, they can try again via the [[WP:OTRS|Open Ticket Request System]]. &lt;br /&gt;
&lt;br /&gt;
The duck test &amp;#039;&amp;#039;&amp;#039;does not apply to article content&amp;#039;&amp;#039;&amp;#039;, and does not trump, or even stand aside, policies such as [[WP:NOR|no original research]], [[WP:VER|verifiability]], and [[WP:NPOV|neutral point of view]]. If there is [[Coot|an animal that &amp;quot;looks like a duck, swims like a duck, and quacks like a duck&amp;quot;]], but zoologists agree that it does not belong in the family [[Anatidae]], then it is not a duck, [[wikt:period#Interjection|period]]. (That being said, some editors believe that [[wp:you don&amp;#039;t need to cite that the sky is blue|you don&amp;#039;t need to cite that the sky is blue]].)&lt;br /&gt;
