"人間は柔軟かつ非常に多くの数で協力できる唯一の動物です"

Humans have this incredible ability to come together and work towards common goals, even when there are thousands or millions of us involved. Think about it—no other species can do that. Sure, ants and bees cooperate, but they do it in rigid, programmed ways. Humans, on the other hand, can adapt and change how we cooperate as situations demand.

This idea was popularized by Yuval Noah Harari in his book "Sapiens". Harari argues that our unique form of cooperation stems from our capacity to believe in shared myths. These myths—like nations, corporations, and religions—allow us to work together in incredibly flexible ways. It’s fascinating when you think about it because it shows how storytelling isn't just for entertainment; it's the backbone of our society.

Let’s dive into a practical example: imagine the creation of the internet. It’s a perfect demonstration of flexible large-scale cooperation. Different companies, governments, and individuals from various cultures and backgrounds came together to create something that didn’t exist before. There was no rigid blueprint; it evolved over time. Each party had its own interests and goals, yet they cooperated enough to create a global network that billions use daily. That's something ants just can’t do.

So how can you apply this wisdom in your life? Understand the power of shared beliefs and narratives. If you're leading a team, focus on building a strong, common vision. When everyone buys into a shared story, they’re more likely to work together effectively, even when challenges arise. Think about how successful companies operate—they have a clear mission statement that resonates with both employees and customers. This shared belief system fuels their growth and adaptability.

Now, let’s get a bit more personal. Imagine you and your friends planning a surprise party for a mutual friend. There’s no detailed plan laid out, but through a series of texts, calls, and meet-ups, you manage to pull off an amazing event. Some friends handle decorations, others manage the guest list, and someone else takes care of food and drinks. This is flexible cooperation in action. Each of you brings different skills and ideas, yet you collaborate effectively. The shared goal of making your friend happy binds you all together, allowing for a fluid and adaptive approach.

In essence, our ability to cooperate flexibly and at scale is what sets us apart and drives our success as a species. By understanding and leveraging this unique trait, you can achieve remarkable things, whether it's in your personal life, at work, or in broader societal contexts. Just remember, it all starts with a shared belief and a willingness to adapt. That's the magic of being human.
