Second Order Thinking

Maps consequence chains the way Howard Marks thinks about investments. You feed it a decision and it walks through first order effects (the obvious), second order (how people respond), and third order (what happens after that). Built around tables that force you to consider customer reactions, competitor moves, and unintended consequences. Most useful when you're making changes that affect behavior, like pricing shifts or policy updates. The framework catches things that look smart initially but backfire once people adapt. It's structured enough to be systematic but flexible enough for strategy, product, or operational decisions.

Core Principle	"First-level thinking says, 'This is a good company, let's buy.' Second-level thinking says, 'This is a good company, but everyone thinks it's great so it's overpriced. Sell.'"
Why This Matters	Most people only consider immediate effects. Second-order thinkers anticipate the cascading consequences—and see opportunities and risks others miss.
