Popular dual-process models of thinking have long conceived intuition and deliberation as two qualitatively different processes. Single-process-model proponents claim that the difference is a matter of degree and not of kind. Psychologists have been debating the dual-process/single-process question for at least 30 years. In the present article, I argue that it is time to leave the debate behind. I present a critical evaluation of the key arguments and critiques and show that—contra both dual- and single-model proponents—there is currently no good evidence that allows one to decide the debate. Moreover, I clarify that even if the debate were to be solved, it would be irrelevant for psychologists because it does not advance the understanding of the processing mechanisms underlying human thinking.

流行的双过程思维模型长期以来一直将直觉和深思熟虑视为两个性质不同的过程。单流程模型的支持者声称，差异是程度问题，而不是种类问题。至少 30 年来，心理学家一直在争论双过程/单过程问题。在本文中，我认为是时候将辩论抛在脑后了。我对关键论点和批评进行了批判性评估，并表明——与双重模式和单一模式的支持者相反——目前没有很好的证据可以让人们决定辩论。此外，我澄清说，即使要解决辩论，这对心理学家来说也无关紧要，因为它不会促进对人类思维背后的处理机制的理解。
