The duck test is a humorous term for a form of inductive reasoning. Induction or inductive reasoning, sometimes called inductive logic, is the process of Reasoning in which the premises of an argument are believed It can be explained this way:
If a bird 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 figure out the true nature of an unknown subject by observing this subject's readily identifiable traits. It is sometimes used to counter abstruse arguments that something is not what it appears to be.
The duck test is common to the United States and the United Kingdom, where it is sometimes called the "British Standard (BS) Duck Test" in imitation of the system of national standards. The United States of America —commonly referred to as the The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located British Standards are produced by BSI British Standards, a division of BSI Group that is incorporated under a Royal Charter and is formally designated

The test is often used to identify something that is supposedly bad, and to justify the use of inductive logic in meting out punishment.
