Conflation is the merging of two or more sets of information, texts, ideas, or opinions into one, often in error.[1] Conflation is defined as 'fusing blending', but is often used colloquially as 'being equal to' - treating two similar but disparate concepts as the same. Merriam Webster suggested this shift in usage happened relatively recently, entering their dictionary in 1973.[2]
In logic, it is the practice of treating two distinct concepts as one, which produces errors or misunderstandings as a fusion of distinct subjects tends to obscure analysis of relationships which are emphasized by contrasts.[3] However, if the distinctions between the two concepts may appear to be superficial, intentional conflation can be desirable for the sake of conciseness and recall.
