---# Second-Order Thinking
## Overview
Second-order thinking, articulated by Howard Marks, moves beyond immediate effects to consider what happens next, and what that leads to. First-order thinking is simplistic ("This action solves the problem"); second-order thinking asks "And then what?" repeatedly.
**Core Principle:** The obvious answer to "What should I do?" is often wrong because it ignores downstream effects.
## When to Use
- Making strategic or architectural decisions
- Evaluating policy or process changes
- Considering incentive structures
- Planning features that change user behavior
- Decisions with long-term consequences
- When the "obvious" solution feels too easy
Decision flow:
```
Decision with consequences beyond immediate? → yes → APPLY SECOND-ORDER THINKING
↘ no → First-order may suffice
```
## When NOT to Use
- The change is local and reversible (a two-way door) with no downstream coupling — just make it and observe.
- The first-order fix is also the correct one and the chain is obvious; don't manufacture speculative cascades.
