Sapiens takes readers on a sweeping journey through the entire history of the human species, from the emergence of Homo sapiens in East Africa roughly 300,000 years ago to the biotechnological and artificial-intelligence revolutions unfolding today. Unfortunately, not everyone’s a historian buff, and may not pick up books specifically about History to read.
But it doesn’t mean there isn’t anything useful or applicable that we can’t learn and use in our daily lives.
Here’s are some insights from Sapiens by Yuval Noah Harari:
Insight 1
Shared Fictions Enable Mass Cooperation
The defining feature of Homo sapiens is not our tools or our intelligence per se, but our ability to create and believe in intersubjective realities—things that exist only because large numbers of people collectively agree they do. Money has no inherent value; a corporation has no physical body; a nation is a line on a map backed by shared belief. Yet these fictions enable millions of strangers to cooperate toward common goals in ways no other species can match. Every large-scale human achievement—from building pyramids to launching satellites—rests on this foundation of shared myth.
Try this
In any organization or community, recognize that culture, brand, and mission statements are shared fictions that coordinate behavior. If you want to lead change, don’t just change processes—change the narrative. Craft a compelling story about who your group is and where it is headed, and repeat it consistently. People align their actions with the stories they believe, so shaping the story is one of the most powerful levers of influence.
Insight 2
The Scientific Revolution Was Fueled by Admitting Ignorance
For most of history, the dominant knowledge traditions—religious and philosophical—assumed that everything important was already known or knowable through scripture and logic. The Scientific Revolution’s radical break was the willingness to say “we don’t know” and then systematically investigate. This marriage of ignorance, observation, and mathematics, backed by imperial and capitalist investment, created a feedback loop of discovery, technology, and power that transformed the world in just five centuries. Science did not just discover facts—it discovered a method for discovering facts.
Try this
Cultivate institutional and personal comfort with the phrase “I don’t know—let’s find out.” In teams, reward curiosity and hypothesis-testing over certainty and authority. When facing a complex problem, resist the urge to rely on existing assumptions. Instead, frame the question as an experiment: define what you’d need to observe to confirm or refute your hypothesis, gather data, and let evidence guide the decision.
