What Primates, Group Dynamics, and the Dunbar Number teach us about Thriving.

How do we create truly connected, thriving teams in an increasingly hybrid world?

Join Tracey Camilleri and Robin Dunbar, co-authors of The Social Brain: The Psychology of Successful Groups, as they delve into the science of social connection and organisational dynamics.

In this thought-provoking episode, Robin Dunbar shares the fascinating origins of the Dunbar Number — 150, the optimal group size for human connection — and explains how group size impacts everything from information flow to organisational success. Together, they explore:

• Why face-to-face interactions still matter in a virtual world

• How organisations can design social strategies to foster trust and collaboration

• The psychological and physical health benefits of strong social bonds

Whether you’re a leader, an HR professional, or simply curious about how relationships shape our workplaces, this conversation offers actionable insights for building better teams and rethinking hybrid work strategies.
