Day 113 of 120 Logic Difficulty 4/10
Reasoning runs on a fast intuitive system and a slow deliberate one
Quick answer
Reasoning runs on a fast intuitive system and a slow deliberate one. Today's question (Dual-process review) asks about a finding from Evans, J. St. B. T. in 2008. The correct option is A fast, autonomous, intuitive system and a slower, deliberate, working-memory-dependent system — full explanation, primary source, and glossary cross-links below.
Today's question
Evans' (2008) Annual Review summarized dual-process theories of reasoning as positing two contrasting modes of processing:
Reveal the answer and explanation
Correct: B — A fast, autonomous, intuitive system and a slower, deliberate, working-memory-dependent system
Evans (2008) reviewed dozens of dual-process accounts that distinguish a fast, automatic, low-load Type 1 system (often labelled intuition) from a slower, working-memory-dependent Type 2 system (deliberate reasoning). Cross-cutting evidence from neuroimaging, individual differences, instructions to 'go with your gut' versus 'think carefully', and cognitive-load manipulations supports a meaningful empirical contrast even if no single theory wins. Evans cautioned against treating the two systems as fully separate or as good-vs-evil; modern revisions describe them as differently parameterized control settings that interact rather than as autonomous agents.

Every Cognition Bible question cites a primary source — a paper, book chapter, or monograph that exists, that we can point to on Google Scholar, and whose finding the question accurately summarizes. No fabricated authority strings, no name-drops without paper-level grounding.
