Which statement about System 1 and System 2 is accurate?

• A. System 1 is slow and deliberate; System 2 is fast and intuitive.
• B. System 1 uses language; System 2 uses imagery.
• C. System 1 is non-analytical; System 2 is deductive reasoning.
• D. Both systems are analytical processes.

Answer: (C)

This item tests how the two thinking modes differ in speed and style. System 1 is fast, automatic, and non-analytical, giving quick impressions and judgments. System 2 is slow, deliberate, and analytical, often using rule-based or deductive reasoning to work through problems.

The statement that best fits this contrast is that System 1 operates in a non-analytical way, while System 2 engages in deductive reasoning. It captures the idea that quick, intuitive thinking drives immediate answers, whereas careful reasoning applies deliberate logic and rules to reach conclusions.

Think of a quick gut reaction to a familiar situation as System 1 in action, versus working through a difficult puzzle or evaluating evidence step by step as System 2. The other descriptions mix up these roles or oversimplify them: one reverses which system is fast versus slow, another ties the systems to specific modalities like language or imagery, and another suggests both are purely analytical, which isn’t accurate.
