Dormant ties
Dormant ties are once-active relationships that have lapsed. Research by Levin, Walter and Murnighan shows reconnecting them is surprisingly valuable.
A dormant tie is a relationship that used to be real — a former colleague, an old classmate, a one-time collaborator — that has simply gone quiet. Nothing ended it; you both just stopped. Network researchers treat dormant ties as a distinct category because they behave like neither current strong ties nor weak ties: the shared history is still there, but the day-to-day overlap is gone.
That odd combination turns out to be their superpower. In a 2011 study in Organization Science, Daniel Levin, Jorge Walter and J. Keith Murnighan asked executives to reconnect with dormant contacts and seek their advice on a live work project. The reactivated relationships delivered advice that was rated as valuable as — and more novel than — advice from current contacts, while still carrying the trust and shared language of the old relationship. Reconnected strong ties, in particular, combined the classic benefits of both tie types: novelty and efficiency plus trust and shared perspective.
For anyone managing a personal network, dormant ties reframe the to-do list. The hundreds of people you 'lost touch with' are not failures or dead entries in your address book — they are a reserve of low-cost, high-trust connections waiting for a reason to wake up.
The 2011 study: what reconnecting actually delivered
Levin, Walter and Murnighan ran their field study with executive MBA students — experienced managers, not undergraduates. Each participant listed dormant contacts (people they had not communicated with in at least three years), reconnected with two of them, and consulted them about an ongoing work project; they did the same with current contacts for comparison. The dormant ties held their own: the value of the advice received compared favorably with advice from active relationships, and it scored higher on novelty, because the dormant contacts had spent the intervening years accumulating different experiences, networks and knowledge. Crucially, trust had not decayed the way contact frequency had — participants reported that the old relationship's mutual understanding snapped back almost immediately. The authors' conclusion was blunt: dormant relationships are an undervalued asset, and executives systematically underuse them because reconnecting feels socially risky when it mostly isn't.
Why reconnecting feels harder than it is
The main obstacle to harvesting dormant-tie value is anticipated awkwardness: 'it's been too long', 'they'll think I only want something'. The research suggests these fears are mostly miscalibrated — the same shared history that makes you hesitate is what makes the other person glad to hear from you. A few honest moves lower the bar further. Name the gap instead of pretending it isn't there ('It's been four years — too long'). Lead with a genuine reason: something that reminded you of them, a question squarely in their territory, or congratulations on a change you noticed. And offer before you ask: a reconnection that opens with something useful for them reads as warmth, not extraction. People who revive two or three dormant ties per month report that the conversations are warmer than expected almost every time — the relationship was paused, not erased.
Building a reconnection habit (and how Endearist helps)
Dormant ties stay dormant for a mundane reason: nothing in your tools ever surfaces them. Your phone sorts contacts alphabetically, your chat apps sort by recency — so the people you haven't spoken to in three years are, by design, invisible. A workable habit needs the opposite sort order. Once a month, pull up the contacts you've gone longest without speaking to, pick two or three where genuine curiosity stirs, and send each a specific, no-pressure message. Endearist makes this loop nearly automatic: because it logs when you last interacted with each person, it can show you exactly who has drifted into dormancy and resurface them gently — locally, on your device, without scoring your friendships in someone else's cloud. The hard part stops being remembering and becomes simply writing the message.
Frequently asked questions
- Why are dormant ties more valuable than new contacts?
- Because they combine what new contacts and close friends each offer separately. Like a stranger, a dormant tie has spent years in different circles accumulating knowledge you don't have — so their input is novel. Unlike a stranger, they already trust you and share your shorthand, so no relationship-building is needed. Levin, Walter and Murnighan found reconnected strong ties delivered novelty, efficiency, trust and shared perspective all at once.
- Is it awkward to reach out after years of silence?
- Far less than you expect. The executives in the Organization Science study consistently anticipated more discomfort than they experienced; once contact was made, the old rapport returned quickly. Acknowledging the gap openly, offering a genuine reason for writing, and expecting nothing in return removes most of the residual awkwardness. The other person usually feels remembered, not used.
- How long does a tie have to be inactive to count as dormant?
- The research used a pragmatic threshold: in the 2011 study, dormant ties were people the participants had not communicated with for at least three years. There's nothing magic about that number — what defines dormancy is that regular interaction has stopped while the underlying relationship was never ended. Many people apply softer personal cutoffs, like a year of silence with someone who used to be close.
