On Reading Widely, Deeply, Exploring, Exploiting

Introduction

The explore/exploit tradeoff is a concept from computer science and decision theory: when do you keep searching for something better versus committing to what you’ve found? It maps surprisingly well onto how we read. Wide reading is exploration—building a broad map of ideas. Deep reading is exploitation—extracting full value from a rich vein. Both matter, and the tension between them shapes what kind of thinker you become.

Key Points

• The explore/exploit framework and how it applies to reading and learning
• What wide reading provides that deep reading can’t, and vice versa
• How to recognize when you’re stuck in a rut versus appropriately going deep
• The role of serendipity in intellectual development
• Building a personal reading practice that balances both modes

Conclusion

The best readers do both. Exploration keeps you from becoming a narrow specialist who misses the bigger picture. Exploitation keeps you from becoming a dilettante who knows a little about everything and a lot about nothing. The skill is knowing when to switch.
