Introduction

This Knowledge Project podcast episode features Shane Parrish interviewing Scott Page, a professor of complex systems, about mental models. The discussion centers on how mental models help us understand complexity, the value of cognitive diversity, and how to teach children about complex systems. The interview uses examples from various fields, including finance, business, and policy, to illustrate the concepts.

Key Takeaways

1. Mental Models and Complexity: Individual brains aren't equipped to handle the world's complexity; therefore, utilizing multiple mental models—different frameworks for understanding—is crucial. Cognitive diversity, where individuals hold varying models, enhances understanding and problem-solving.
2. Wisdom Hierarchy: The hierarchy progresses from raw data to information (structured data), knowledge (understanding relationships between information), and finally, wisdom (applying knowledge to problems). Mental models are particularly relevant at the knowledge and wisdom stages.
3. Multiple Models Approach: Utilizing multiple models—even conflicting ones—provides a more robust and comprehensive understanding of complex situations than relying on a single model. This approach is particularly valuable in dealing with unpredictable or rapidly changing environments.
4. Iterating Models: Applying models involves assessing the context (actors involved, rationality of decision-makers), examining the logic and assumptions within the model, and recognizing potential systemic feedbacks or inconsistencies. A combination of formal models (e.g., linear regression) and human judgment often yields the best results.
5. Teaching Complexity: Teaching children about complexity involves fostering a love for learning, encouraging the development of innate abilities, and connecting knowledge to meaningful purposes. The "logic, structure, function" framework helps understand how structures emerge and their significance. Using games like Rush Hour demonstrates how mental models facilitate problem-solving across different disciplines.
