A term coined by Ronald Langacker to describe a specific instance of the exclusionary fallacy.

To commit the rule/list fallacy is to exclude, for instance, listing a unit such as a word if there is a rule which can predict the lexical unit. This line of reasoning is fallacious as it adopts the view that one must posit either rules or lists but not both. Langacker argues that there is a third choice: to posit rules and lists.
