“Old wine in a new bottle”: Are different terminologies on dual processing conceptually the same? [Author Accepted Manuscript]

Objectives: Dual processing theory is among the most influential theories in cognitive psychology. It distinguishes two kinds of human thinking; one that is fast, intuitive, and effortless; and the other that is slow, deliberate, and effortful. Interestingly, these two types of human thinking have been described using many different terms by various researchers. How similar or different are these terms and related constructs? Methods: We analyzed the dual-processing literature, conducted a thought experiment, and analyses using the machine learning model BERT (SCEPTER) to compare the similarity and difference of the terms and constructs. Results: Findings show that, though these terms are lexically different, what researchers describe is, at the core, very similar. The various terms are ‘old wine in a new bottle.’ Conclusions: We provide possible reasons for this coinage of terminology and present a rationale for careful deliberation before introducing new terms.
