How do you prioritize friendships?

To prioritize friendships effectively, sort your relationships into tiers based on closeness and the contact frequency each relationship needs to stay healthy. Inner circle (3–5 people): weekly or biweekly contact. Close friends (10–15 people): monthly contact. Good friends (30–40 people): quarterly contact. Acquaintances: occasional contact when paths cross. Allocate your outreach effort accordingly rather than trying to maintain everyone equally.

What is the Dunbar number for friendships?

Robin Dunbar, a British anthropologist at Oxford, proposed that humans can cognitively maintain stable relationships with approximately 150 people. Within that 150, he identified nested layers: roughly 5 intimate relationships, 15 close friendships, 50 good friends, and 150 acquaintances. Each layer requires progressively less contact time but provides proportionally less emotional closeness.

Is it okay to have different tiers of friends?

Yes, having different tiers of friends is not only normal but inevitable — it reflects the natural variation in closeness across your relationships. Every person you know occupies a different place in your social world. Acknowledging this explicitly, rather than feeling guilty about it, helps you invest your limited social energy where it matters most while still valuing the broader network.

How to Tier Your Friendships: A System for Prioritizing Who Gets Your Time

There's a common guilt associated with adult friendships: the feeling that you're a bad friend because you don't contact everyone as often as you should. The person you were close to in your first job. The college friend you haven't spoken to in eight months. The neighbor who moved away two years ago.

This guilt is often a response to treating your social relationships as a flat, undifferentiated list — as if every person in your life deserves equal contact frequency and equal emotional investment. They don't, and pretending they do leads to either exhaustion or paralysis.

A tiering system solves this by making explicit what's already true: different relationships have different natural levels of closeness, and different levels of closeness require different amounts of active maintenance.

The Science Behind Social Layers

Robin Dunbar, a British anthropologist at Oxford, proposed based on studies of brain size and social group sizes across primates that humans can cognitively maintain stable relationships with approximately 150 people. Within that 150, he identified nested layers with characteristic sizes:

~5 people: intimate relationships — the people you turn to in a crisis, who know everything about your life
~15 people: close friends — people you'd invite to a small dinner, who would notice if you disappeared
~50 people: good friends — people you enjoy and maintain periodic contact with
~150 people: acquaintances — people you know and would acknowledge warmly, but don't maintain actively

Each layer outward requires progressively less contact time to maintain and provides proportionally less emotional closeness. This isn't a value judgment — it's a description of how human social cognition actually works.

A Practical 3-Tier System

For most people, a simplified 3-tier system is easier to implement than all five Dunbar layers:

Tier	Size	Contact Frequency	Characteristics
Inner Circle	3–7 people	Weekly or biweekly	Mutual depth, crisis support, share everything
Close Friends	10–20 people	Monthly	Genuine warmth, know main life events, reciprocal
Good Friends	30–50 people	Quarterly or when prompted	Enjoy each other's company, warm when in contact

How to Do the Tiering

Get a piece of paper or open a notes app. Write down every person who matters to you across all contexts: family, childhood friends, college, work, current life. Don't filter yet.

Then ask three questions for each person:

Would I call this person if something major happened in my life?
Would I notice — and care — if they disappeared from my life?
Does contact with them leave me feeling energized or drained?

The people where the answer to all three is "yes, yes, energized" belong in your inner circle or close friends tier. Adjust based on current contact frequency and reciprocity.

What Tiering Actually Changes

Once you've tiered your relationships, the practical change is in how you allocate outreach effort:

Inner circle: proactive, scheduled, high frequency — don't let these lapse
Close friends: regular reminders to check in, respond warmly to their outreach
Good friends: reach out when prompted (birthdays, life events, something that reminded you of them), maintain when they reach out

This doesn't mean you love good friends less than close friends. It means you're being honest about what each relationship requires to be healthy — and prioritizing accordingly.

Social Compass lets you set different reminder cadences for different friends — weekly for your inner circle, monthly for close friends, quarterly for the rest. Free to start.

Tiers Are Not Fixed

People move between tiers over time. A college friend who's been in Tier 3 for years might re-enter Tier 1 when you both move to the same city. A close friend might drift to Tier 2 after a life transition that changes their availability or your connection. Someone new enters your life and belongs in Tier 1 almost immediately.

The system is descriptive, not prescriptive. It reflects current reality and helps you act accordingly — not lock people into permanent categories.

The goal is to stop feeling guilty about friendships you can't maintain at full intensity, while ensuring the ones that matter most get the attention they deserve. For practical contact frequency guidance, see our article on how often you should contact friends.
