# Idea
Dual-process models postulate the existence of two *qualitatively* different thought processes, one [[intuitive thinking style|intuitive]] and one [[analytic thinking style|deliberative]]. They argue that there is a qualitative difference between intuitive and deliberate processing.
They refer to a class of psychological models in which two processes—[[system 1 thinking|type 1 processes]] and [[system 2 thinking|type 2 processes]]—with *qualitatively* different properties compete to determine the outcome of a computation. The exact processes vary across models/theories.
It is a special case of [[multiple-process models]], which are contrasted with [[single-process models]].
Many versions of dual-process models:
- [[System 1 and System 2]], deliberative vs affective
- automatic vs controlled
## Defining features intuitive and deliberative processes
- [[deliberative processes engage working memory]]
- [[deliberative processes engage cognitive decoupling and mental simulation]]
- [[intuitive processes are autonomous]]
Other features that co-vary (see [[De Neys 2021 on dual- and single-process models of thinking|De Neys 2021]])

## Evidence for dual-process models
People often hold [[contradictory beliefs]] and the [[the observation of simultaneously held contradictory beliefs supports dual-process models]].
