Does this sound like the set of challenges you might be facing?
- If you asked me to name my actual five closest people I’m not sure I could
- I let all my looser acquaintances go totally silent because they felt less important than my close people
- My calendar is packed with people and plans and yet I feel weirdly lonely in all of it
- I still feel just as close to people I haven’t actually talked to in months, and I keep assuming the bond is fine on warmth alone
- I’m trying to keep everyone close at once and the result is that I’m stretched thin and fully present with no one
Practices that may help
- Dunbar's Number
Robin Dunbar's research proposes that the human neocortex supports a stable social group of roughly 150 people, with nested layers of closer relationships (5, 15, 50) requiring progressively more time investment to maintain. The 150-person figure has observational support across hunter-gatherer societies, historical military units, and company sizes; the nested-layer model is more contested. The practical implication is that meaningful relationships are a limited resource that require deliberate allocation. - Map your social layers using Dunbar's concentric circles
Know which five people are in your inner circle and who fills the 15 and 50 layers.
Dunbar's Number - Maintain weak ties for information and opportunity
The 50-to-150 layer isn't maintenance overhead — it's your network's reach.
Dunbar's Number - Prioritize depth over breadth in social investment
Having five genuinely close friends is more protective of wellbeing than having fifty adequate ones.
Dunbar's Number - Invest contact time as the currency of closeness
Relationships are maintained by time investment; without it, they drift toward outer layers.
Dunbar's Number - Triage your outer layers to protect inner-layer capacity
You cannot expand your inner circle without something moving outward — the constraint is cognitive, not motivational.
Dunbar's Number - Use shared activities rather than conversation alone to build bonds
Doing things together creates bonds more efficiently than talking about the relationship.
Dunbar's Number - Encode numbers with the Major System
Convert digits to consonant sounds, then flesh out into memorable words or images.
Peg System Mnemonics, Made Practical - Levels of Processing: Why Depth of Encoding Determines What You Remember
Craik and Lockhart’s (1972) levels of processing framework proposes that memory is a by-product of the type of processing performed on incoming information: shallow processing (appearance, sound) produces weak, short-lived traces, while deep processing (meaning, elaboration, connection to prior knowledge) produces strong, durable ones. The implication for learning is that how you engage with material matters more than how many times you see it. - Extend to the Person-Action-Object (PAO) system
Assign a person, an action, and an object to each two-digit number to compress large sequences.
