The Social Connectivity in the Digital Age

Social Connectivity in the Digital Age.  “Dunbar's Number”

Dunbar’s number is “a suggested cognitive limit to the number of people with whom one can maintain stable social relationships."

We’re all connected more than ever - right?  Some might say yes, but for years now we are seeing people becoming less connected and more isolated even though a human being on the other side of the world is simply a click away.  

The theory of Dunbar's Number offers invaluable insights into the nature of human relationships. I’ve used it for over 35 years to explain the power of connection and how humans can navigate this pathway. It remains just as relevant today as It was in the early years of my psychology degree (too far back for me to want to admit to).

Originating from the work of British anthropologist Robin Dunbar, the concept suggests that there is a cognitive limit to the number of individuals with whom one can maintain stable social relationships—relationships in which an individual knows who each person is and how each person relates to every other person. 

This number is famously capped at approximately 150. But the theory delves deeper, proposing concentric circles of closeness: 5 intimate bonds, 15 good friends, 50 friends, and 150 meaningful contacts. In our current age of digital disconnection, understanding and applying the principles of Dunbar's Number can reshape our approach to personal and professional networking, emphasising the timeless value of trust, familiarity, and genuine connection.

What is Dunbar's Number?

At its core, Dunbar's Number is not just about the limits of social connections but about the quality and depth of these connections. It suggests that while we may engage with hundreds or even thousands of people through social media platforms, the number of relationships in which meaningful emotional investment is possible remains limited. This realisation prompts a reevaluation of how we cultivate and prioritise relationships in both personal and professional spheres.  

And this is even more relevant today as time has become a precious commodity we all guard fiercely.

Digital Disconnection in a Hyper-Connected World

Despite the unprecedented access to networks and information, the digital age has ushered in a sense of isolation and superficiality in social interactions. Social media platforms, while offering the illusion of connectivity, often lead to relationships characterised by breadth, not depth. Dunbar's Number highlights the disconnect between the vast number of online connections and the limited capacity for meaningful relationships, underscoring the importance of nurturing deeper connections amidst the noise of digital engagement.

The Power of In-Person Networking

In the context of professional networking, the implications of Dunbar's Number are never more relevant. The theory suggests that the most effective networks are not necessarily the largest but those that are nurtured through regular, meaningful interactions. In-person networking events, coffee meetings, and direct engagement offer opportunities to build the trust and familiarity that form the foundation of strong business relationships. 

These interactions allow for the nuances of body language, tone, and emotional connection that are often lost in digital communication, fostering a level of trust and understanding that is difficult to achieve online.

Think about it in your own life, the people you feel truly connected with are those you have invested time in person with.  You may supplement these with digital connections, but we crave that personal touch.

Trust, Likability, and Business Success

The concentric circles of Dunbar's Number also offer a framework for understanding how trust and likability influence business success. Transactions and collaborations are more likely to occur within the inner circles, where trust is highest. 

This understanding can inform networking strategies, emphasising the cultivation of a core network of contacts with whom strong, trust-based relationships are maintained. In doing so, professionals can leverage the natural human inclination to do business with those they know, like, and trust, translating personal connections into professional opportunities.

Strategies for Applying Dunbar's Number:

1. Prioritise Quality Over Quantity: In both personal and professional contexts, focus on deepening relationships with a core group of individuals rather than expanding your network indiscriminately.  Less is ABSOLUTELY more.

2. Invest Time Wisely: Allocate time and energy to nurture relationships within your inner circles. Regular, meaningful interactions are key to maintaining these connections.

3. Leverage Technology Mindfully: While recognizing the limitations of digital interactions, use technology to complement rather than replace face-to-face connections. Social media and messaging apps can be effective tools for staying in touch between in-person meetings.

4. Engage in Active Listening: Whether in personal conversations or professional meetings, active listening fosters deeper understanding and trust, solidifying relationships.  This is one of the biggest losers in the digital age of everything NOW.  But it remains the powerhouse of connection.

5. Be Authentic: Authenticity is crucial in building and maintaining trust. Genuine interactions, even if they occur less frequently, are more valuable than numerous superficial engagements.  I know it's easy to say, but often it's not that easy to do.  


As we navigate the complexities of the digital age, Dunbar's Number serves as a crucial reminder of the fundamental nature of human social interaction. It challenges us to reconsider the value we place on the quantity of our connections, urging instead a focus on the quality and depth of those relationships. In the realm of professional networking, this understanding becomes a strategic asset, highlighting the importance of trust, likability, and personal connection in achieving business success. 

By applying the principles of Dunbar's Number, we can cultivate more meaningful relationships, both personally and professionally, fostering a sense of connection and community that transcends the limitations of our digital world.

30+ years on, I love this theory and apply it in my everyday life and business, and hope you can too.
