Nexus Reflection: The Power of Human Networks

I recently read Nexus, Yuval Noah Harari's newest book. Remember him, author of Sapiens? That book was so powerful that I couldn't wait to get my hands on his next work.

Nexus delves into the profound role that networks have played in shaping human history. Harari argues that the power of human networks lies in their ability to connect individuals, foster cooperation, and build systems that transcend individual limitations. From early tribal societies to the global digital era, networks have been the backbone of human advancement. However, Harari also warns of the fragility and risks associated with these networks when they are mismanaged or misaligned with ethical principles.

In this reflection, we will explore the role of networks in today’s organizations, examine how networks can go astray, and provide actionable guidance for leaders to create meaningful and healthy networks in the modern workplace.

Humans Love Stories

Stories are the crux of how we make meaning, establish credibility, and reinforce (and share) culture.  Story telling takes on a unique form in all human systems. We tell and internalize "the story of us" related to our favorite sports teams, representation of national pride, within our families, and of course, in our organizations (even regions or departments within an organization).

This ability to give language to shared beliefs and forge symbolic connections allows us to develop networks far more complex and expansive than any other species. From ancient mythology to modern digital platforms, these networks have powered humanity’s progress and shaped societies. Harari argues that our unique capacity to create and sustain such systems explains much of our success—and also why maintaining and evolving these networks remains critical.

The Role of Networks in Today’s Organizations

At their core, networks are about relationships—connections that enable individuals to collaborate, share knowledge, and achieve collective goals. In organizations, networks are not just formal hierarchies or reporting lines; they are the informal webs of communication, trust, and influence that shape culture and drive innovation.

Consider the following ways networks manifest in organizations today:

• Knowledge Sharing: Networks facilitate the exchange of expertise and insights across departments, creating opportunities for cross-functional collaboration.
• Innovation: By connecting diverse perspectives, networks spark creativity and enable problem-solving.
• Resilience: Strong networks provide emotional and professional support during times of change, helping organizations adapt more effectively.
• Purpose: Networks allow employees to find communities within the organization that align with their values, fostering a sense of belonging.

Harari’s historical lens shows us that successful networks are those that balance individual needs with collective purpose. In today’s fast-paced and interconnected world, this balance is more critical than ever.

How Networks Can Go Astray

While networks have the potential to amplify human potential, they can also become sources of dysfunction when mismanaged. Harari highlights several pitfalls of networks, and these are evident in organizational contexts:

• Echo Chambers: Networks can reinforce groupthink when diversity of thought is absent, leading to stagnation or poor decision-making.
• Exclusion: Informal networks can create cliques or power dynamics that marginalize individuals who are not part of the “in-group.”
• Overextension: Too many connections or unstructured communication can overwhelm employees, leading to burnout and inefficiency.
• Toxicity: Without clear norms or accountability, networks can harbor negativity, gossip, or undermining behaviors that erode trust.

These risks underscore the importance of intentionality in building and maintaining networks. Left unchecked, even well-intentioned networks can devolve into barriers to progress.

What Leaders Can Do to Foster Healthy Networks

Creating space for meaningful and healthy networks in today’s world of work requires deliberate effort. Leaders play a pivotal role in shaping the culture and structure that enable networks to thrive. Here are three key areas of focus:

1. Design with Intent

• Facilitate Connection: Create opportunities for employees to connect authentically, such as through mentorship programs, affinity groups, or cross-functional projects.
• Encourage Diversity: Build networks that include a variety of perspectives, backgrounds, and experiences to foster creativity and resilience.
• Establish Clear Norms: Set expectations for how networks operate, emphasizing transparency, inclusivity, and respect.

2. Empower with Tools

• Leverage Technology: Use collaboration tools like Slack, Teams, or Miro to support seamless communication and knowledge sharing.
• Provide Resources: Equip employees with training and resources to navigate and contribute effectively to networks.
• Monitor Dynamics: Use analytics to understand how networks are functioning and identify areas for improvement.

3. Model Healthy Behavior

• Lead by Example: Demonstrate the values and behaviors you want to see within networks, such as active listening, humility, and openness.
• Recognize Contributions: Celebrate and reward employees who contribute positively to networks, highlighting their impact on organizational success.
• Address Dysfunction: Intervene promptly when networks exhibit toxic behaviors, ensuring accountability and resolution.

Reimagining Networks for a Sustainable Future

The power of human networks lies in their ability to unite people toward shared goals. Yet, as Harari’s Nexus reminds us, this power must be wielded thoughtfully. Leaders have a responsibility to nurture networks that are inclusive, resilient, and aligned with organizational purpose.

Imagine organizations where networks are not just tools for productivity but engines of human connection and innovation. By embracing Harari’s lessons and applying them with intentionality, leaders can create environments where employees thrive and collective potential is realized.

As you reflect on the networks within your organization, consider:

• How do your networks foster collaboration? What structure has been designed into them to encourage people to engage? To feel a sense of shared purpose and commitment?
• How do networks within your organization ensure inclusion of diverse voices, perspectives, talents, identities, and experiences? What mechanisms are in place to quickly identify and make adjustments to networks as they grow or membership changes?
• As the world of work is constantly changing—from hybrid to technological advances—how do you ensure the design of networks continues to evolve to meet the needs of people and your mission?

The answers to these questions will shape the future of work. By reimagining networks as spaces for meaning, connection, and growth, we can build organizations that are not only effective but also deeply human.
