# Reification (fallacy) | | Reification is a fallacy of ambiguity, when an abstraction is treated as if it were a concrete real event or physical entity. In other words, it is the error of treating something that is not concrete, such as an idea, as a concrete thing. A common case of reification is the confusion of a model with reality: "the map is not the territory". | |-|-| | | wikipedia:: [Reification (fallacy)](https://en.wikipedia.org/wiki/Reification_(fallacy)) | [[Abstract|Abstract and concrete]]
