Day 20 of 150 Logic Difficulty 4/10
System 1 is fast and automatic; System 2 is slow and deliberate
Quick answer
System 1 is fast and automatic; System 2 is slow and deliberate. Today's question (Dual-process theory) asks about a finding from Stanovich, K. E., & West, R. F. in 2000. The correct option is Fast, automatic, intuitive — full explanation, primary source, and glossary cross-links below.
Today's question
In dual-process accounts of reasoning, "System 1" thinking is best described as:
Reveal the answer and explanation
Correct: B — Fast, automatic, intuitive
Stanovich & West (2000) consolidated decades of dual-process research into the now-dominant System 1 (fast, automatic, associative) versus System 2 (slow, deliberate, rule-based) frame, popularized by Kahneman in 2011. System 1 generates an answer; System 2 monitors and can override — but only when engaged. The two-system metaphor is descriptive rather than anatomical: there is no single "System 1 region" in the brain.
