Title: The Great Mental Models Volume 3
Author: Rhiannon Beaubien and Rosie Leizrowice
Category: Science & Discovery, Decision-Making & Critical Thinking, Career Growth, Motivation & Self-Improvement
Why do diets fail and companies stall? Sam and Sophie dive into mental models that reveal the hidden systems behind everyday chaos, from feedback loops to power laws, and how to use them to make smarter decisions.
They walk through the core concepts of systems thinking: feedback loops (reinforcing and balancing), stocks and flows, and the principle of delay. Then they shift to mathematical models like the law of large numbers, regression to the mean, and power law distributions. Along the way, they use examples like compound interest, bank runs, and why a baseball player's amazing season is likely followed by a worse one.
If you've ever felt like you're just reacting to events instead of understanding them, this episode gives you a mental toolkit to see the bigger picture. The takeaway: stop asking what to do, and start asking what system you're operating in.
