In this Beyond the Boardroom episode, host Aleksandra King sits down with Professor Robin Dunbar, the world-renowned evolutionary psychologist from the University of Oxford who formulated the famous *Dunbar’s Number*. They explore the science behind how humans form social connections and challenge common assumptions about friendship circles. Drawing on Dunbar’s research, the conversation reveals why social media “friends lists” can be misleading and why most people can realistically maintain only about **150 meaningful relationships. Aleksandra, a female podcast host UK known for her fearless, no-holds-barred style, guides the discussion from personal anecdotes to hard science, cutting through the noise to uncover what truly drives human bonding.
Episode Highlights
- Dunbar’s Number – The 150-person limit: discover why your online network has strict boundaries. In this episode Dunbar explains why your extended “friends list” isn’t what it seems and how roughly **150 stable relationships** is the cognitive limit for most adults.
- Intimacy Layers – The human social spectrum: learn about the circles of connection from your core 5 “shoulders-to-cry-on” friends to the 15-person sympathy group and the 50-person “weekend barbecue” layer. Aleksandra and Dunbar unpack how often you truly connect with each group.
- Time Investment – The cost of closeness: understand why building one new close friendship demands about **200 hours** of in-person time. Dunbar lays out the brutal math: to add a person to your inner circle, someone else may have to slip out.
- Positive Gossip & Trust – Rediscover gossip: Dunbar reframes gossip as an information-sharing tool that helps manage social networks. He also exposes why breakdowns of trust in families are so catastrophic and how “over-investment” in loved ones can make splits painfully raw
- The “Icebreaker” of Singing – The surprising power of song: singing together is revealed as one of the most powerful ways to create instant bonds. Learn how group singing synchronizes emotions and rapidly builds community trust
- Homophily (The “Jane Austen Problem”) – Similarity and friendship: explore our instinct to seek friends like ourselves and why chasing a “perfect” connection (the Jane Austen problem) can actually limit our social growth.
- Spotting Toxic People – Navigating the outliers: understand the psychology of toxic individuals. Dunbar outlines how some people are simply genetically wired to be selfish or manipulative, and offers insight on keeping your social circle healthy.
Throughout the episode, Dunbar provides a fresh lens for evaluating your own social world. The conversation is both entertaining and packed with actionable insights. Whether discussing trust and family bonds or practical “social toolkit” strategies for business and life, Aleksandra’s boardroom energy pushes the dialogue beyond surface-level chatter. By the end, listeners gain a clearer understanding of what makes friendships thrive (or fail) and how *social science* can inform our everyday relationships
