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.

Why it works

Attempting to maintain 150 people at close-friend intensity leads to the subjective experience of being stretched thin and present nowhere. The social brain has a processing budget: more complexity in one relationship leaves less for others. Deliberate triage — consciously accepting that some relationships will stay in outer layers — is not coldness but a precondition for genuine intimacy with the people in the inner rings.

How to do it

1. Accept that outer-layer relationships (50 and 150 circles) require less active maintenance — occasional contact is appropriate and adequate.
2. For relationships that are consuming inner-circle effort without inner-circle reciprocity, gently adjust expectations and contact frequency.
3. Use life transitions (moves, job changes, children) as natural reset points to re-evaluate layer assignments.
4. Distinguish between relationships that feel draining because they need maintenance and ones that genuinely belong in an outer layer.

Evidence

The cognitive load of social tracking is supported by the neocortex-group-size correlation across primates; that humans experience relationship maintenance as a limited-bandwidth activity is observationally consistent. Dunbar's (1992) neocortex-ratio analysis across primates is the empirical anchor for treating group size as a capacity limit, and Dunbar (2016) shows the limit persists even when digital channels lower the cost of contact. (mechanistic)

The triage practice is a personal advice application of Dunbar's descriptive research; Dunbar himself describes group sizes, not optimal pruning strategies. This is practitioner inference from the data.

Common mistake

Guilt-driven maintenance of outer-layer relationships at inner-circle effort, which depletes the capacity needed for the relationships that actually sustain you.
