Coaching practices for Dunbar's Number During a Big Change
Describe almost anything you are working through and IX Coach finds the practices whose real-world fit is closest. For Dunbar's Number During a Big Change, these are the strongest matches in the current practice library.
Does this sound like the set of challenges you might be facing?
- I let all my looser acquaintances go totally silent because they felt less important than my close people
- If you asked me to name my actual five closest people I’m not sure I could
- 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
- My calendar is packed with people and plans and yet I feel weirdly lonely in all of it
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. - 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 - 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 - 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 - 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 - Update beliefs incrementally, not all at once
New evidence should shift your probability somewhat — rarely from 5% to 95% in one step.
Bayesian Thinking: How to Update Beliefs Rationally - Decompose the unknown into knowable sub-problems
Break the question you cannot answer directly into smaller questions you can.
Fermi Estimation - Update beliefs frequently and in small increments
When new evidence arrives, adjust your probability estimate — even if the change is small.
Superforecasting - Update incrementally as evidence arrives rather than waiting for certainty
State your current best-guess probability, identify what would shift it, and update when that evidence arrives.
