The duck test—"If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck"—suggests that something can be identified by its habitual characteristics.

The duck test does not apply to non-obvious cases. Unless there is evidence which proves otherwise beyond a reasonable doubt, editors must assume good faith from others.

Usage

The "duck test" is meant to be used for internal processes within Wikipedia. For example, consider that "

sock-puppet, and act in consequence. If "User:Example3
" 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.

(However, check Example1 and Example2 aren't longstanding editors with similar names -

it does happen
).

Variations

" Even though they all look different, we can spot that you recruited them...

A variation of the duck test in conversations can be found in community discussions where consensus is required, most obviously

ganged up together

The duck test may also apply to

The duck test does not apply to article content, and does not trump, or even stand aside, policies such as

neutral point of view. If there is an animal that "looks like a duck, swims like a duck, and quacks like a duck", but zoologists agree that it does not belong in the family Anatidae, then it is not a duck, period. (That being said, some editors believe that you don't need to cite that the sky is blue
.)
