dual process theory

Syllable breakdown

Dictionary meaning

a framework in cognitive psychology proposing that human thinking operates through two distinct systems: System 1, which is fast, automatic, intuitive, and largely unconscious, and System 2, which is slow, deliberate, effortful, and rule-governed; popularised by Daniel Kahneman in his book Thinking, Fast and Slow, the theory explains a wide range of cognitive biases as the product of System 1 heuristics that operate without conscious oversight and sometimes produce systematic errors in judgment
