DECISION MAKING: WHY PEOPLE DO NOT ALWAYS THINK RATIONALLY
People make thousands of decisions every day, ranging from simple choices such as selecting a meal to more significant matters involving finances, careers, and relationships. For many years, economists assumed that individuals generally make rational decisions by carefully considering all available information and selecting the option that maximises personal benefit. However, research in psychology has increasingly challenged this assumption.
One influential area of study concerns cognitive biases, systematic patterns of thinking that can lead to errors in judgment. For example, people often give greater importance to information that confirms their existing beliefs while ignoring evidence that contradicts them. This tendency, known as confirmation bias, may affect decisions in areas such as politics, health, and investment.
Researchers have also examined the role of intuition in decision making. Intuition refers to judgments that are reached quickly and with little conscious effort. Some studies suggest that intuitive decisions can be surprisingly effective, particularly when individuals have extensive experience in a specific field. Nevertheless, scientists caution that intuition is not always reliable and may lead to mistakes when situations are unfamiliar or highly complex.
Another factor influencing decisions is the framing effect. Experiments have demonstrated that people sometimes react differently to identical information depending on how it is presented. Individuals may be more willing to accept a medical treatment described as having a 90 per cent survival rate than one described as having a 10 per cent mortality rate, despite the two statements conveying the same statistical information.
Risk-taking behaviour has also attracted scientific attention. Some researchers propose that age, personality, and social influences may affect an individual's willingness to take risks. However, considerable variation exists among people, and scientists have not yet fully explained why some individuals consistently engage in risky behaviour while others avoid it.
Despite decades of investigation, many aspects of human decision making remain poorly understood. Researchers continue to debate the extent to which decisions are influenced by unconscious processes and whether people can be trained to overcome cognitive biases.
Questions 1–12
Do the following statements agree with the information given in the passage?
Write
TRUE if the statement agrees with the information
FALSE if the statement contradicts the information
NOT GIVEN if there is no information about this.
1. Economists once believed that people usually make decisions in a logical manner.
2. Psychologists agree that individuals always choose the option that provides the greatest benefit.
3. Confirmation bias involves paying attention only to information that supports existing opinions.
4. Confirmation bias affects political decisions more frequently than health-related decisions.
5. Intuitive decisions may be successful when people possess considerable experience.
6. Scientists believe that intuition can never lead to errors.
7. People sometimes respond differently to the same information when it is presented in different ways.
8. A treatment with a 90 per cent survival rate is statistically better than one with a 10 per cent mortality rate.
9. Researchers suggest that personality may influence risk-taking behaviour.
10. Scientists completely understand why certain individuals repeatedly engage in risky activities.
11. Researchers know that unconscious processes influence exactly half of all decisions.
12. Scientists are still discussing whether cognitive biases can be reduced through training.
Summary
This passage explores the psychology of human decision making and challenges the traditional economic assumption that people always make rational choices. It discusses cognitive biases, particularly confirmation bias, which can influence judgments by causing individuals to favour information that supports existing beliefs. The passage also examines intuition, highlighting that rapid judgments can sometimes be effective, especially when based on experience, but may also lead to errors. Additionally, it explains the framing effect, where people react differently to the same information depending on its presentation, and investigates factors influencing risk-taking behaviour. Despite extensive research, many aspects of decision making, including unconscious influences and methods for reducing cognitive biases, remain subjects of ongoing scientific debate.
