What is Bounded Rationality? Definition, Examples & Limitations

📚 Quick Study Guide: Bounded Rationality

• 💡 Definition: Bounded rationality, a concept by Herbert A. Simon, suggests that human decision-making is limited by the information available, the cognitive limitations of the mind, and the finite amount of time we have to make a decision.
• 🧠 Core Idea: Rather than making perfectly rational decisions (which would require unlimited information and processing power), individuals "satisfice" – they aim for a satisfactory outcome rather than an optimal one.
• ⏳ Limitations: Key limitations include incomplete information, cognitive biases (e.g., confirmation bias, availability heuristic), time constraints, and the sheer complexity of many real-world problems.
• ⚖️ Contrast with Perfect Rationality: Traditional economic theory often assumes perfect rationality, where individuals have full information, unlimited cognitive ability, and always choose the optimal outcome. Bounded rationality offers a more realistic view.
• 🌍 Real-World Examples:
  • 🛒 Shopping: Choosing a product based on a few key features and price, rather than researching every single option available globally.
  • 💼 Job Search: Accepting the first good job offer that meets criteria, instead of waiting for a potentially "perfect" one that might not exist or take too long to find.
  • 🏠 House Buying: Selecting a home that meets most essential needs within budget, without exhaustively comparing every single property on the market.
• 📊 Implications: Bounded rationality helps explain phenomena like heuristics, biases, and why people often make decisions that appear suboptimal from a purely rational perspective. It's crucial in behavioral economics.
