    Rethinking Relationships in Modern Life

    Dunbar’s Number—the idea that humans can sustain about 150 meaningful relationships—has often been cited as a kind of upper limit of social capacity. But there’s a catch: Dunbar’s research comes largely from survival contexts. Soldiers, tribes, or explorers under hazardous conditions can sustain that many bonds because their very lives depend on it.

    That raises a question: is it even realistic to apply the same model to our own prosperous and distracted society, where survival doesn’t force us into deep dependence on one another?

    The Reality of Time in Modern Life

    Families today often struggle to carve out even thirty minutes of true connection per week per person. Careers, commutes, and constant media distractions consume most of our energy. Unlike survival situations, there is no “hazardous condition” compelling us to give that time to each other.

    Instead, research suggests that most people sustain relationships in smaller tiers:

    • ~5 intimate relationships (spouse, kids, best friend)
    • ~15 close friends (trusted, dependable)
    • ~50 casual friends (social, supportive but not deeply involved)
    • ~150 acquaintances (faces you recognize, people you greet, maybe occasional interaction)

    The idea of giving thirty minutes a week to 150 people simply does not fit modern life.

    What Purpose Is Strong Enough?

    If survival is not the binding force, what kind of purpose can motivate us to invest deeply in others? A few possibilities stand out:

    • Shared mission: groups that see themselves on a spiritual journey together, not just social clubs.
    • Shared suffering: support networks for addiction, illness, grief, or persecution.
    • Shared growth: intentional groups that pursue holiness, spiritual discipline, or formation.

    Without this sense of necessity, relationships often default to shallow banter, logistics, or distractions.

    A Practical Adaptation: The MicroSphere

    If thirty minutes per week per person is unrealistic, perhaps the MicroSphere model can be reframed for modern life:

    • Core MicroSphere: 3–5 people with whom you share weekly conversation, prayer, or accountability. (This might be two hours together, but it touches everyone deeply.)
    • Support Sphere: 10–15 people you connect with at least monthly, sharing faith and encouragement.
    • Outer Sphere: 50–150 acquaintances you know, pray for, and occasionally interact with.

    This layered approach makes room for reality: we cannot invest equally in everyone. But we also cannot reduce community to casual surface contact.

    Why This Matters for the Church

    If we want the Church to be more than Sunday attendance, we need these MicroSpheres of intentional connection. Banter and shared projects may keep us loosely tied, but true growth happens when men and women share purpose, open up about meaning, and walk with one another in faith.

    Dunbar’s insights remain helpful—but only if we adapt them. Our challenge today is not survival, but mission. And that requires building communities strong enough to resist isolation, and deep enough to carry us together toward Christ.

  • Microsphere Relationships:

    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.
