One of the significant assumptions in decision-making and game theory is rational behavior. What is rational behavior? We are going to answer in this post.
Rational behavior in game theory refers to the way players make decisions based on logical reasoning, aiming to maximize their payoffs (and knowing how to do so), given their knowledge of the game and other players' strategies. Game theory provides a framework to analyze these decisions in strategic interactions.
In real life, we are not always able to understand clearly our payoff, and in many cases, we let our feelings control our behavior. That is not rational. How to make rational decision-making?
Rational decision-making involves a structured
approach to making logical and well-informed choices. Here's a step-by-step
guide to rational decision-making:
1. Identify the Problem or Decision to be
Made
- Description: Clearly define the issue or
decision you face. Understand the nature of the problem, the context, and
why it needs to be addressed.
- Example: You must decide whether to
accept a new job offer or stay in your current position.
2. Gather Relevant Information
- Description: Collect all pertinent
information that can inform your decision. This includes data, facts, and
insights related to the options available.
- Example: Research the new job’s salary,
benefits, company culture, and career growth opportunities, and compare
them with your current job’s conditions.
3. Identify Alternatives
- Description: List all possible options or
courses of action available to you. Consider a range of choices to ensure
a comprehensive evaluation.
- Example: Your alternatives include
accepting the new job, staying in your current job, or even looking for
other opportunities elsewhere.
4. Evaluate the Alternatives
- Description: Assess each alternative
based on various criteria such as costs, benefits, risks, and alignment
with your goals. Consider both short-term and long-term impacts.
- Example: Compare the job offers by
evaluating the salary, work-life balance, potential for career
advancement, and any other factors that are important to you.
5. Weigh the Evidence
- Description: Analyze the information and
evaluations to determine which alternative offers the most significant
overall benefit or utility. This step often involves quantitative and
qualitative analysis.
- Example: Create a pros and cons list for
each job offer, or use a decision matrix to rate each alternative based on
your criteria.
6. Make the Decision
- Description: Based on the evaluation,
choose the alternative that best meets your needs and objectives. Make a
decision that maximizes benefits and minimizes downsides.
- Example: After evaluating the options,
you might accept the new job offer if it significantly improves your
salary and career prospects.
7. Implement the Decision
- Description: Put your chosen course of
action into effect. Plan and execute the necessary steps to implement your
decision.
- Example: Notify your current employer of
your resignation, complete any necessary paperwork for the new job, and
prepare for the transition.
8. Monitor and Evaluate the Results
- Description: After implementation,
monitor your decision's outcomes to ensure it achieves the desired
results. Evaluate whether the decision was effective and make adjustments
if necessary.
- Example: Assess how well the new job
meets your expectations regarding career growth, job satisfaction, and
work-life balance. Make changes if you find any issues or if the situation
evolves.
9. Learn from the Experience
- Description: Reflect on the
decision-making process and its outcomes. Identify what worked well and
what could be improved for future decisions.
- Example: Analyze what factors most
influenced the right choice and apply these insights to future decisions.
Summary
- Identify the Problem: Define the decision
you need to make.

based on criteria.
- Weigh the Evidence: Analyze which option
provides the most significant benefit.
