Cognitive Reflection System 1 vs. System 2 Thinking Questions and Answers

Question 1

Which of the following scenarios is the BEST example of relying on System 2 thinking?

Accepted Answer

Calculating the total cost, including taxes and a tip, for a complicated group dinner bill.

Answer

System 2 thinking is slow, deliberate, and analytical, requiring conscious effort. [2, 9] Calculating a complex bill involves step-by-step reasoning and mental energy, which are hallmarks of System 2. [8] The other options describe fast, automatic, and intuitive processes characteristic of System 1 thinking. [1, 13]

Question 2

A classic Cognitive Reflection Test question asks: 'A bat and a ball cost $1.10 in total. The bat costs $1.00 more than the ball. How much does the ball cost?' What is the common, intuitive, but incorrect answer that demonstrates System 1 thinking?

Accepted Answer

10 cents

Answer

The intuitive answer that quickly comes to mind for many people is 10 cents. This is a result of System 1's fast, associative nature, which incorrectly subtracts $1.00 from $1.10. [11] Engaging System 2 reveals that if the ball were 10 cents, the bat would be $1.10, for a total of $1.20. The correct answer is 5 cents. [5, 11]

Question 3

A project manager is faced with a minor, routine issue that is very similar to a problem solved successfully on many previous projects. According to Daniel Kahneman's model, which cognitive system is MOST likely and appropriately used to make a quick decision?

Accepted Answer

System 1, because it relies on past experiences and patterns to make fast, efficient judgments.

Answer

System 1 thinking is ideal for routine, repetitive tasks where patterns and past experiences can guide decisions quickly and efficiently. [1, 12] Since the problem is minor and familiar, relying on the fast, automatic System 1 is the most efficient approach, saving cognitive energy for more complex issues. [10, 12]

Question 4

The primary purpose of the Cognitive Reflection Test (CRT) is to measure an individual's ability to:

Accepted Answer

Override an initial, intuitive 'gut' response and engage in more deliberate, analytical thinking.

Answer

The CRT is specifically designed to assess the tendency to resist an immediate, intuitive answer (System 1) and activate the more effortful, analytical System 2 to find the correct solution. [4, 6] The questions are structured so that the intuitive answer is appealing but wrong. [14]

Question 5

Which of the following characteristics is exclusively associated with System 1 thinking?

Accepted Answer

Automatic and unconscious

Answer

System 1 is defined by its fast, automatic, unconscious, and intuitive nature. [1, 9] It operates with little to no effort and without a sense of voluntary control. [13] The other options—slow, conscious, effortful, logical, and analytical—are all defining characteristics of System 2 thinking. [2, 8]
