Apply Dunbar Number Principles to Help Users Prioritize Relationships

Allow users to visualize and organize their network using concepts inspired by the Dunbar number. The idea that people can maintain different levels of relationships (e.g., close, casual, acquaintance) based on cognitive and time limits.

For example:

Tier 1 (“Core 50”): contacts to keep in touch with quarterly

Tier 2 (“Extended 100”): semiannual check-ins

Tier 3 (“Outer circle”): annual or ad-hoc connections

This framework could help Dex users set realistic “Keep in Touch” frequencies, identify who belongs in which tier, and visualize relationship strength or recency at a glance.

Value:

Encourages more intentional relationship management

Prevents overcommitment by suggesting realistic touchpoint frequencies

Makes “Keep in Touch” feel more human and personalized
