Overview
About 70,000 years ago Homo sapiens underwent a Cognitive Revolution that enabled new modes of thought and communication. This shift from biological to cultural evolution allowed small bands of humans to cooperate flexibly and spread across the globe. The founder lens is simple: keep the parts that improve judgment, simplify decisions, and make the next move easier to explain.
Founder lessons worth borrowing
Lesson 1. An explosion of symbolic thought and language enabling shared fictions and flexible cooperation.
For founders, this matters when the pressure is high and the temptation is to act before thinking clearly.
Lesson 2. To gossip and communicate about individuals and shared fictions, enabling large-scale cooperation.
For founders, this matters when the pressure is high and the temptation is to act before thinking clearly.
Lesson 3. It raised total food output but often reduced individual well-being through harder labor, disease and social inequality.
For founders, this matters when the pressure is high and the temptation is to act before thinking clearly.
Lesson 4. Shared myths and imagined orders (religion, laws, money) that allow strangers to cooperate at large scale.
For founders, this matters when the pressure is high and the temptation is to act before thinking clearly.
