Shared Fictions Enable Large-Scale Human Cooperation
Sapiens: A Brief History of Humankind by Yuval Noah Harari (2014) · Sapiens: A Brief History of Humankind (2014)
Humans dominate the planet not because of individual strength or intelligence, but because of our unique ability to create and collectively believe in shared fictions—money, nations, laws, corporations—that allow flexible, large-scale cooperation.
Core Concepts
The Problem
Why can millions of strangers cooperate in complex societies while other animals max out at small groups?
The Claim
Shared fictions (intersubjective realities) enable humans to organize around common goals that exist only in collective imagination.
Key Evidence
- •Money has no intrinsic value; its worth is entirely a collective belief
- •Nations are imagined communities that inspire intense loyalty and sacrifice
- •Religions and ideologies unite vast numbers of people across time and space
- •Corporations and legal entities exist only because we agree they do
Practical Implication
Our ability to maintain and update our shared stories determines our capacity to solve global problems; when shared fictions break down, so does cooperation.
Nuance & Limits
Not all shared fictions are benign—some can be used to justify oppression or violence. The stories require constant retelling and reinforcement, and they can be reshaped for better or worse.
