Behavioral Science 101: Thinking Systems Cognitive Reflection Test CRT

What This Is

The Cognitive Reflection Test (CRT) is a measure of cognitive ability that assesses an individual's tendency to engage in reflective thinking, particularly in situations where an intuitive answer might be misleading. This test matters for understanding human behavior because it highlights the limitations of System 1 thinking and the importance of System 2 reflection in decision-making. For example, a government nudge that increased retirement savings by making the default option an automatic 5% contribution, rather than requiring individuals to opt-in, exploited the tendency for people to rely on System 1 thinking and overlook the benefits of saving.

Key Theories & Models

• Dual-Process Theory (System 1 and System 2): System 1 is fast, automatic, intuitive; System 2 is slow, deliberate, analytical – errors often arise when System 1 overrides System 2. This theory is crucial for understanding the CRT, as it highlights the importance of System 2 reflection in decision-making.
• Prospect Theory (Kahneman & Tversky): People value gains and losses differently, leading to risk-averse behavior in gains and risk-seeking in losses – explains framing effects. Prospect theory is relevant to the CRT because it shows how people's intuitive judgments can be influenced by the way information is framed.
• Heuristics and Biases: Mental shortcuts, such as the availability heuristic and the representativeness heuristic, can lead to systematic errors in judgment. The CRT is a tool for identifying these biases and promoting more reflective thinking.
• The Somatic Marker Hypothesis: Emotions play a crucial role in decision-making, particularly in situations where there is uncertainty or risk. The CRT can help individuals develop a greater awareness of their emotional responses and make more informed decisions.
• The Theory of Planned Behavior: Behavioral intentions are influenced by attitudes, subjective norms, and perceived behavioral control. The CRT can help individuals develop more positive attitudes towards reflection and decision-making.
• The Self-Regulation Model: Self-regulation is the ability to control one's thoughts, feelings, and behaviors. The CRT can help individuals develop greater self-regulation skills and make more informed decisions.
• The Cognitive Load Theory: Cognitive load refers to the amount of mental effort required to perform a task. The CRT can help individuals manage their cognitive load and make more informed decisions.
• The Fuzzy-Trace Theory: People use different types of mental representations, such as verbatim and gist representations, to process information. The CRT can help individuals develop a greater awareness of these different representations and make more informed decisions.

Step-by-Step Application

1. Administer the CRT: Use the CRT as a tool to assess an individual's tendency to engage in reflective thinking.
2. Identify System 1 and System 2 thinking: Recognize when individuals are relying on System 1 or System 2 thinking and provide feedback on the importance of System 2 reflection.
3. Foster a growth mindset: Encourage individuals to view challenges as opportunities for growth and development, rather than threats to their ego.
4. Provide feedback and coaching: Offer feedback and coaching to help individuals develop more reflective thinking skills.
5. Use the CRT as a diagnostic tool: Use the CRT as a diagnostic tool to identify areas where individuals may need additional support or training.

Common Misconceptions

• Misconception: The CRT is a measure of intelligence.
• Correction: The CRT is a measure of cognitive ability, specifically the tendency to engage in reflective thinking. While there may be a correlation between CRT scores and intelligence, they are not the same thing.
• Misconception: The CRT is only relevant to complex decision-making tasks.
• Correction: The CRT is relevant to any situation where individuals need to make decisions or judgments, regardless of the complexity of the task.
• Misconception: The CRT is only useful for identifying biases and heuristics.
• Correction: The CRT is a tool for promoting more reflective thinking and decision-making, not just identifying biases and heuristics.

Exam/Application Tips

• Be aware of the distinction between availability heuristic and representativeness heuristic: The availability heuristic refers to the tendency to overestimate the importance of information that is readily available, while the representativeness heuristic refers to the tendency to judge the likelihood of an event based on how closely it resembles a typical case.
• Understand the difference between loss aversion and risk aversion: Loss aversion refers to the tendency to prefer avoiding losses over acquiring gains, while risk aversion refers to the tendency to prefer certain outcomes over uncertain outcomes.
• Be able to explain the concept of framing effects: Framing effects refer to the way in which information is presented, which can influence an individual's decision-making.

Quick Practice Scenario

A subscription service auto-renews unless the user unticks a small checkbox. Which behavioral principle is at work and why?

Answer: The default effect is at work because the subscription service is using the default option to influence the user's decision. The user is more likely to stick with the default option (auto-renewal) than to take the effort to change it.
