Warnock's dilemma, named for its originator Bryan Warnock, is the problem of interpreting a lack of response to a posting on a mailing list, Usenet newsgroup, or Web forum. It occurs because a lack of response does not necessarily imply that no one is interested in the topic, and could have any one of several different implications, some of which are contradictory. Related terms are commonly used in the context of trying to determine why a post has not been replied to, or to refer to a post that has not been replied to.
|“||The problem with no response is that there are five possible interpretations:
—Bryan C. Warnock, 
Since Warnock's original description of the dilemma in August 2000, the expression has become widely used in the Perl world and has seen some adoption by webloggers. It is commonly used to refer to the uncertainty of deciding which of any number of reasons caused an absence of responses. Oft-seen phrases include:
- "He was Warnocked."
Someone posted a question, but nobody replied.
- "Warnock applies."
Warns readers not to draw conclusions based on the lack of response.
Traditionally, a dilemma is a problem which offers two possibilities, neither of which are practically acceptable. Therefore Warnock's Dilemma, as originally phrased, is not a true dilemma. Properly speaking it is a logical disjunction. However, many modern dictionaries consider this restriction needless and allow "dilemma" to be used colloquially to refer to a difficult situation with any number of choices, since the term polylemma, which is the appropriate description, has not come to widespread use. Alternatively, the literal-minded can consider the Dilemma to be about whether people are not replying to messages because 1) they are not interested, or 2) for some other reason.
