Where Real Belonging Begins
A number of years ago, I came across an article called the “monkey sphere,” which was built on Robin Dunbar’s research into human social networks. Dunbar suggested that the size of our neocortex places a natural limit on how many people we can truly know and relate to. For humans, he estimated the number is around 150 people — what’s often called Dunbar’s Number.
But there’s a catch: to sustain that many relationships, you’d need to dedicate around 40% of your weekly time (about 67 hours) to them. That works out to roughly 30 minutes per person, per week.
This struck me:
- The people in our microsphere — the ones we average 30 minutes a week with — are those we trust, learn from, and share life with. These are mentoring, collegial, or teamwork relationships where we actually need to learn how to get along.
- The macrosphere is made up of the many others we know, but more distantly — acquaintances, useful contacts, neighbors.
- At the center are our nucleus relationships — the people who need at least 30 minutes of our time daily. These include family, closest friends, and of course, God.
- Being famous is when more people know you than you know them.
- Being a fan is knowing someone who doesn’t know or care about you.
- Being a teacher / instructor / influencer implies the information is flowing out with little or no feedback.
It makes me wonder:
- How many microsphere relationships do we actually sustain today — with family, extended family, coworkers, fellow parishioners, or in hobbies?
- How many are necessary to feel truly at home in a parish — 5, 10, 20?
We live in a world where loneliness is widespread, and many people are drowning in macrosphere connections (social media followers, casual contacts) but starving for microsphere ones. We let busyness and distraction push aside the very relationships that would make us feel grounded, known, and supported.
