&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;The '''Duck test''' is a humorous term for a form of [[abductive reasoning]]. This is its usual expression:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;blockquote&amp;gt;If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck.&amp;lt;/blockquote&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The test implies that a person can identify an unknown subject by observing that subject's habitual characteristics. It is sometimes used to counter abstruse, or even valid, arguments that something is not what it appears to be.&lt;br /&gt;
