(I thought people might find this interesting. My meditation teacher often talks about relationships in these terms. I'm definitely lacking in the As and Bs at 56)
British Anthropologist Robin Dunbar categorized relationships into circles of closeness, intimacy and frequency of contact - As, Bs, Cs, Ds, etc
1. Layer A: Intimate Circle (Dunbar’s “5” – Closest Bonds)
• Closeness Level: Maximal emotional depth; these are your “shoulders to cry on”—people you’d turn to in crisis, share vulnerabilities with, or even grieve deeply if lost.
• Frequency of Contact: Very high—daily or near-daily (e.g., texts, calls, or in-person time totaling 40+ hours/month per person).
• Why It Matters: This layer handles ~60–70% of your emotional support needs. Dunbar notes falling in love can “cost” you 1–2 spots here, as it demands huge time/energy.
• Example: A lifelong best friend or romantic partner you confide in without filters.
2. Layer B: Close Sympathy Group (Dunbar’s “15” – Good Friends)
• Closeness Level: High trust and empathy; you know their quirks, share laughs/tears, and offer advice, but it’s not as raw as Layer A.
• Frequency of Contact: Frequent—weekly (e.g., 20–30 hours/month total across the group, like group chats or casual meetups).
• Why It Matters: These folks provide ~20–30% of your emotional bandwidth. They’re the ones who make social events fun and buffer stress.
• Example: Ride-or-die pals from college or work you see for brunches or game nights.
3. Layer C: Band of Bandits (Dunbar’s “50” – Casual Friends/Acquaintances with History)
• Closeness Level: Moderate; shared context (e.g., hobbies or past adventures), but less personal—conversations stay lighter, with occasional deeper chats.
• Frequency of Contact: Occasional—monthly or every few months (e.g., 10–20 hours/month total, like bumping into them at events).
• Why It Matters: This layer adds variety and networking (e.g., job tips), but it’s more about fun than support. Dunbar says it’s where “clans” form in evolutionary terms.
• Example: Old classmates or hobby group members you catch up with sporadically.
4. Layer D: Clansmen/Stable Contacts (Dunbar’s “150” – General Network)
• Closenes Level: Low; you know who they are and have a vague history, but little emotional tie—more like “friendly faces.”
• Frequency of Contact: Infrequent—quarterly or less (e.g., <10 hours/month total, via holidays or social media pings).
• Why It Matters: This is the cognitive limit for “meaningful” ties; beyond it, relationships feel superficial. It’s your safety net for broader community.
• Example: Extended colleagues or distant relatives you nod to at gatherings.
