For the use of „the duck test“ within the Wikipedia community, see Wikipedia:DUCK.
The duck test is a humorous term for a form of inductive reasoning. This is its usual expression:
If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck.
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 arguments that something is not what it appears to be.“
