Cognitive Reflection Test Overriding Intuitive Errors 2 — Questions and Answers
Question 1: A pen and a notebook cost $6.20 in total. The notebook costs $6.00 more than the pen. How much does the pen cost?
- $0.10 (Correct answer)
- $0.20
- $0.60
- $6.00
Correct answer: $0.10
If the pen is $0.10, the notebook is $6.10, which totals $6.20 with a $6.00 gap.
Question 2: If it takes 8 machines 8 minutes to make 8 gadgets, how long would 40 machines take to make 40 gadgets?
- 40 minutes
- 8 minutes (Correct answer)
- 5 minutes
- 1 minute
Correct answer: 8 minutes
Each machine makes one gadget in 8 minutes, so any equal number of machines and gadgets still takes 8 minutes.
Question 3: A vine doubles its coverage on a pond every day and covers it fully in 60 days. On what day was it half covered?
- Day 30
- Day 59 (Correct answer)
- Day 58
- Day 15
Correct answer: Day 59
Since it doubles daily, the day before full coverage it was exactly half covered.
Question 4: Which mental process does the CRT primarily measure by using questions with a tempting wrong answer?
- The ability to suppress an intuitive response and reason deliberately (Correct answer)
- Long-term memory recall
- Reading speed
- Spatial visualization
Correct answer: The ability to suppress an intuitive response and reason deliberately
The CRT tests whether a person can override a fast, intuitive answer in favor of reflective reasoning.
Question 5: In dual-process theory, the fast, automatic answer that CRT items trigger comes from which system?
- System 1 (Correct answer)
- System 2
- System 3
- The working-memory buffer
Correct answer: System 1
System 1 produces fast, intuitive responses, which the CRT tempts you to accept.
Question 6: A bag and a keychain cost $1.10 together, and the bag costs $1.00 more than the keychain. What does the keychain cost?
- $0.05 (Correct answer)
- $0.10
- $0.15
- $1.00
Correct answer: $0.05
The keychain is $0.05 and the bag is $1.05, giving a $1.00 difference and $1.10 total.
Question 7: Why do many educated people still get CRT items wrong?
- The intuitive wrong answer feels obviously correct and goes unchecked (Correct answer)
- The questions require advanced calculus
- The wording is intentionally ungrammatical
- The items rely on obscure vocabulary
Correct answer: The intuitive wrong answer feels obviously correct and goes unchecked
CRT errors stem from accepting a fluent, confident intuition without verifying it.
