When Will This Friendship Die?

Based on Robin Dunbar\'s friendship research (Roberts & Dunbar 2011, Dunbar 2018). Friendships need ~1-2 meaningful interactions/month to sustain. Below threshold, bonds decay over months-years. The tool gives a directional estimate — not destiny.

Frequently Asked Questions

Where's the science?
Robin Dunbar's research on friendship: maintenance requires ~150-200 hours of contact to form a "good friend" bond, and ~1-2 meaningful interactions/month to sustain it. Below this, bonds decay. Studies (Roberts & Dunbar 2011): friendships that drop below 6 contacts/year reach "acquaintance" status within ~2 years.
Why is this not depressing?
Because it's actionable. Most people don't notice friendships decaying — they wake up at 40 realizing nobody calls. This tool tells you which friendships need a coffee or a call THIS WEEK, while there's still relational substance to renew.
How accurate is the timeline?
Order-of-magnitude estimate based on Dunbar research. Real friendships vary: some survive years of zero contact (deep history). Others decay in months. The model uses simple multipliers for distance, life-stage divergence, and emotional history. Use it as a directional nudge, not a death sentence.
How do I revive a decaying friendship?
Three concrete moves: (1) Voice notes — 10× more relational signal than texts, 50× faster than calls. (2) Yearly tradition — annual trip, birthday call, recurring dinner. (3) Ask for help — counterintuitive, but receiving requests strengthens bonds. Don't wait for "the right time" — reaching out now resets the decay clock.
