The bounded rationality model of decision making is a concept that explains how individuals make decisions within the limitations of their cognitive capacity and available information.
Decision making is a critical aspect of daily life that affects personal, business, and political outcomes.
This article aims to provide a comprehensive explanation of the bounded rationality model of decision making, its key features, applications, and criticisms.
Herbert Simon and the Concept of Bounded Rationality
Herbert Simon was an American economist and social scientist who made significant contributions to the field of decision making. He was awarded the Nobel Memorial Prize in Economic Sciences in 1978 for his work on bounded rationality, which challenged the traditional rational choice theory.
Herbert Simon’s Background and Contributions
Herbert Simon was born in Milwaukee, Wisconsin, in 1916. He obtained his Bachelor’s degree in Political Science from the University of Chicago in 1936 and his Ph.D. in Political Science from the same institution in 1943. He joined the faculty of Carnegie Mellon University in 1949, where he remained until his death in 2001.
Simon’s contributions to the field of decision making were significant. He challenged the traditional rational choice theory, which assumed that individuals were rational and made decisions by weighing all the available information. Simon argued that individuals had limited cognitive capacity and were unable to process all the information available to them. Therefore, individuals made decisions based on heuristics and biases that were not necessarily optimal but satisfactory.
Development of the Bounded Rationality Concept
Simon introduced the concept of bounded rationality in his book “Administrative Behavior,” published in 1947. He argued that the traditional rational choice theory was unrealistic and that individuals were limited in their ability to process information. He proposed that individuals used heuristics and shortcuts to make decisions instead of engaging in an exhaustive search for all the available information.
Simon’s bounded rationality concept emphasized that decision making was a process of satisficing instead of optimizing. Satisficing meant that individuals made decisions that were “good enough” instead of striving for the best outcome. The concept suggested that individuals faced a trade-off between the effort required to make an optimal decision and the potential benefits of that decision.
Comparison with the Rational Choice Theory
The rational choice theory assumes that individuals make decisions by weighing all the available information and selecting the option that provides the highest utility. The theory assumes that individuals have unlimited cognitive capacity and that they can process all the information available to them. However, the bounded rationality model challenges this assumption and suggests that individuals have limited cognitive capacity and cannot process all the information available to them.
The bounded rationality model also suggests that individuals use heuristics and biases to make decisions, which may lead to errors and suboptimal outcomes. In contrast, the rational choice theory assumes that individuals are rational and do not make errors in decision making.
Key Features of the Bounded Rationality Model
The bounded rationality model proposes that individuals make decisions based on limited cognitive capacity and the use of heuristics and biases. It emphasizes that decision-making is a process of satisficing instead of optimizing, and it views the decision-making process as a series of steps.
Decision-Making Process as a Series of Steps
The bounded rationality model suggests that decision-making is a process that occurs in a series of steps. These steps include:
- Identification of the problem or decision to be made.
- Gathering and processing information relevant to the decision.
- Generating alternative courses of action.
- Evaluating the alternatives and selecting the best course of action.
The model suggests that individuals may use heuristics and biases during each of these steps, which may lead to suboptimal outcomes.
Limited Cognitive Capacity and Information Processing
The bounded rationality model proposes that individuals have limited cognitive capacity and cannot process all the available information. Therefore, individuals make decisions based on incomplete information and may not consider all the relevant factors.
For example, a person may decide to buy a new car based on the brand reputation and price, without considering other important factors such as fuel efficiency, safety ratings, or maintenance costs. This decision may be satisfactory but not optimal.
Use of Heuristics and Biases
The bounded rationality model suggests that individuals use heuristics and biases to make decisions. Heuristics are shortcuts or rules of thumb that individuals use to simplify the decision-making process. Biases are systematic errors that individuals make when processing information or evaluating options.
For example, a person may use the availability heuristic, which is a shortcut that involves making a decision based on the information that is most readily available. This heuristic may lead to suboptimal outcomes if the readily available information is not representative of the overall situation.
Emphasis on Satisficing Instead of Optimizing
The bounded rationality model emphasizes that decision-making is a process of satisficing, which means that individuals make decisions that are satisfactory but not necessarily optimal. This approach recognizes that individuals face a trade-off between the effort required to make an optimal decision and the potential benefits of that decision.
For example, a person may decide to purchase a car that meets most of their requirements, even though it may not be the best car available in the market. This decision may be satisfactory but not optimal.
Applications of the Bounded Rationality Model
The bounded rationality model has several applications in various fields, including business, politics, and personal decision-making. In this section, we will discuss some of the applications of this model.
Business Decision Making
In business, decision-making is an essential process that can determine the success or failure of an organization. The bounded rationality model can help business leaders understand how individuals make decisions and how they can improve their decision-making processes. Some examples of how this model can be applied in business include:
- Understanding customer decision-making: By understanding the limitations and biases of customers, businesses can create products and services that are more appealing to them. For example, a company may use the anchoring bias to influence customers’ perception of pricing by setting a high initial price and then offering discounts.
- Simplifying complex decisions: Businesses can use heuristics to simplify complex decisions. For example, a company may use the recognition heuristic to evaluate the quality of a product or service by its popularity.
- Evaluating alternatives: The bounded rationality model can help businesses evaluate alternatives when making decisions. For example, businesses can use satisficing to evaluate alternatives that meet minimum requirements instead of searching for the best option.
Political Decision Making
In politics, decision-making can have a significant impact on society. The bounded rationality model can help policymakers understand how individuals make decisions and how policies can be designed to encourage better decision-making. Some examples of how this model can be applied in politics include:
- Nudging: Policymakers can use nudges to encourage individuals to make better decisions. For example, governments may use default options to encourage citizens to save more for retirement.
- Simplifying complex policies: Policymakers can use heuristics to simplify complex policies. For example, a government may use a simple tax system to reduce the cognitive burden on taxpayers.
- Evaluating alternatives: The bounded rationality model can help policymakers evaluate alternatives when making decisions. For example, policymakers can use satisficing to evaluate policies that meet minimum requirements instead of searching for the best option.
Personal Decision Making
In personal decision-making, individuals may face several challenges, such as limited information, cognitive biases, and time constraints. The bounded rationality model can help individuals understand how they make decisions and how they can improve their decision-making processes. Some examples of how this model can be applied in personal decision-making include:
- Evaluating options: Individuals can use satisficing to evaluate options that meet minimum requirements instead of searching for the best option. For example, when buying a new phone, individuals can set minimum requirements such as price range, battery life, and camera quality.
- Avoiding biases: Individuals can use awareness of biases to avoid making suboptimal decisions. For example, individuals can avoid the anchoring bias by evaluating options without considering the initial price.
- Simplifying decisions: Individuals can use heuristics to simplify decisions. For example, individuals can use the recognition heuristic to evaluate the quality of a product or service by its popularity.
Criticisms and Limitations of the Bounded Rationality Model
Despite the many applications and benefits of the bounded rationality model, it has also faced some criticisms and limitations. In this section, we will discuss some of the main criticisms of this model.
Critiques of the Limited Cognitive Capacity Assumption
One of the main assumptions of the bounded rationality model is that individuals have limited cognitive capacity and information processing capabilities. However, some critics argue that this assumption may be too simplistic and fails to capture the complexity of human decision-making. They argue that individuals can use various strategies to overcome the limitations of their cognitive capacity, such as dividing complex decisions into smaller parts or relying on external aids such as calculators.
Lack of Empirical Support for Some Heuristics and Biases
Another criticism of the bounded rationality model is the lack of empirical support for some of the heuristics and biases it proposes. While some heuristics and biases have been extensively studied and validated, others have not been rigorously tested or have produced inconsistent results. This lack of empirical support raises questions about the validity and reliability of the bounded rationality model.
Difficulty in Measuring and Assessing Satisficing
The bounded rationality model emphasizes that individuals may satisfice rather than optimize when making decisions. However, satisficing can be difficult to measure and assess, as it is often subjective and context-dependent. This can make it challenging to evaluate the effectiveness of decisions made under the satisficing framework.
Conclusion
In conclusion, the bounded rationality model of decision-making, developed by Herbert Simon, provides a valuable framework for understanding how individuals make decisions in various fields. This model emphasizes the limited cognitive capacity and information processing capabilities of individuals, and the use of heuristics and biases to simplify decision-making processes. It also emphasizes the concept of satisficing, which suggests that individuals make decisions that are good enough rather than optimal.

Importance of Bounded Rationality in Understanding Decision Making
The bounded rationality model is important because it recognizes that individuals face limitations in their cognitive capacity and information processing capabilities. It acknowledges that individuals cannot always make fully rational decisions due to these limitations, and that they may use heuristics and biases to simplify decision-making processes. This recognition is important because it allows decision-makers to understand the factors that may influence their decisions and to develop strategies to mitigate the effects of these factors.
Future Directions for Research and Application
There is still much to learn about the bounded rationality model and its applications. Future research could focus on the following areas:
- Further exploration of the heuristics and biases proposed by the bounded rationality model and their effects on decision-making processes.
- Development of methods to measure and assess satisficing.
- Investigation of the boundary conditions for the bounded rationality model, such as the nature of the decision, the decision-maker’s expertise, and the context in which the decision is made.
In terms of application, decision-makers can use the insights provided by the bounded rationality model to develop strategies to improve decision-making processes. For example, decision-makers can:
- Identify and mitigate biases that may influence their decisions.
- Simplify complex decisions into smaller, more manageable parts.
- Seek out diverse sources of information to make more informed decisions.
Overall, the bounded rationality model provides a useful framework for decision-makers to understand and improve their decision-making processes.
