How to Network (The Research Shows Your Most Valuable Contacts Aren't Who You Think)

By Gwyndalyn Henderson

The conventional networking playbook — attend events, collect contacts, expand your LinkedIn connections, follow up after conferences — produces the feeling of activity without producing the outcomes it promises. The research on how professional opportunities actually travel through social networks explains why. Mark Granovetter, sociologist at Stanford University, published the finding that changed how network scientists think about professional relationships: in his landmark 1973 study of how people found jobs, Granovetter found that the contacts most useful for accessing new opportunities were not close friends and colleagues — people with whom you share regular communication and overlapping social circles — but what he called weak ties: acquaintances, former colleagues, people you know peripherally. The counterintuitive reason is structural: your close contacts are largely in your same circles, have access to the same information you do, and know the same people you know. Your weak ties have moved into different circles. They carry information and access that your strong-tie network cannot provide, precisely because they are not embedded in your existing world.

The network research that has followed Granovetter's foundational work has refined and extended this finding in ways that are directly useful for anyone trying to build a professional practice or access new opportunities. Adam Grant's research at the Wharton School on the performance patterns of givers versus takers and matchers in professional environments, and David Burkus's research on dormant tie reactivation, together produce a specific and evidence-backed networking strategy that is almost nothing like what most people are doing. This post covers what Granovetter's weak tie theory, Grant's give-first research, and Burkus's dormant tie findings collectively show about how professional networks actually generate value — and what to do about it.

Granovetter: Why Weak Ties Outperform Strong Ties for Opportunities

Mark Granovetter's 1973 paper "The Strength of Weak Ties," published in the American Journal of Sociology, is one of the most cited papers in social science — not because it describes something exotic, but because it overturns an intuition that most people carry without examining it. The intuition is that strong relationships — close friends, trusted colleagues, family members — are the most useful professional contacts because they know you well, care about your outcomes, and are most likely to advocate for you. Granovetter's data showed the opposite: among the professionals he surveyed about how they found their jobs, the most common answer was through contacts they saw occasionally or rarely, not through close friends or current colleagues.

The mechanism is structural rather than motivational. Your strong ties are embedded in the same professional and social circles you are. They know the same job openings, have access to the same referral networks, and move in the same information ecosystem. A close friend who works in your field has a high probability of already knowing what you know. An acquaintance who left your industry two years ago for a different sector, or who moved to a different city and built a new professional circle, now has access to information, contacts, and opportunities that your strong-tie network does not. The value of a weak tie is not that the person cares more — it is that they carry information from a part of the network you cannot see.

The practical implication cuts directly against the most common networking mistake: over-investing in relationships with people you already know well (deepening strong ties) while under-investing in the maintenance of peripheral relationships (weak ties) and entirely neglecting the people you have lost touch with completely (dormant ties, which the subsequent research shows are the most undervalued category of all).

Burkus: The Most Underrated Contacts You Already Have

David Burkus, organizational psychologist and author of Friend of a Friend, has produced the most accessible synthesis of network research for professional application — and his most striking finding extends Granovetter's weak tie theory to a category most people have written off entirely: dormant ties, defined as professional contacts you once knew meaningfully but have not been in contact with for three or more years.

Burkus's research, drawing on survey data and network analysis, found that dormant ties have two properties that make them disproportionately valuable for accessing new opportunities. The first is the bridging property Granovetter identified for weak ties, but amplified: a contact who was in your professional orbit three to five years ago and has since built a career in a different direction, moved into a different industry, or risen to a different level in their organization has now accumulated an entirely different network from the one they had when you knew them. Reconnecting with them gives you a bridge to a network that has grown and diversified since you last spoke. The second property is trust: unlike a cold contact, a dormant tie already has a relationship context with you. They remember you, have a prior positive association, and are meaningfully more likely to respond to outreach and to extend goodwill than a stranger would be.

The combination of bridging access and pre-existing trust makes dormant ties statistically more useful for generating new opportunities than either strong ties (too much network overlap) or cold contacts (too little relationship context). Most people have dozens of dormant ties they have not thought about in years — former colleagues, people from graduate programs, contacts from previous cities, people from past projects or companies — who are now in entirely different professional circles and would, in most cases, be genuinely glad to hear from someone they once worked with or respected.

Grant: Why Givers Win in Long-Horizon Networks

Adam Grant, professor of organizational psychology at the Wharton School at the University of Pennsylvania, built the most systematic large-sample research account of how different orientations to professional relationships predict career outcomes. His research, published in Give and Take, identified three fundamental reciprocity styles: givers (people who contribute to others without expecting a specific return), matchers (people who aim for even exchanges), and takers (people who extract more than they contribute). The conventional expectation — that takers succeed at the expense of givers — is partially supported by his data in the short term and completely reversed over longer horizons.

Givers do appear disproportionately at the bottom of professional outcome metrics, because some proportion of them give in ways that are indiscriminate and self-depleting. But givers also appear disproportionately at the top of outcome metrics — outperforming both matchers and takers in long-horizon career success, income, influence, and the quality of their professional networks. The research finding that explains the pattern: giving, in a professional network, builds a compound reputation. Givers become the people that others think of when opportunities arise — not because they asked to be thought of, but because they have established a track record of providing value before being asked. In network terms, givers accumulate goodwill at a scale that creates inbound opportunities that matchers and takers do not receive.

The relevance to networking specifically: most people approach networking with an implicit extraction framing — they are trying to collect contacts who can do things for them, attending events to find people who might hire or refer them, and reaching out when they need something. Grant's research shows this framing is functionally backwards for long-term network building. The highest-ROI networking activities are the ones that create value for others without an immediate expected return: sharing a relevant article with someone who would find it useful, making an introduction that benefits two people in your network, offering feedback or expertise when someone is working on a problem in your domain, being genuinely helpful in online communities where your expertise is relevant.

The 5-10-20 Give-First Framework

A practical give-first networking structure that aligns with Grant's research and the weak and dormant tie findings operates at three tiers, with different investment levels for different relationship categories.

The 5 (Deep Relationships): Five relationships that receive consistent, meaningful investment — not daily contact, but regular attention, genuine interest in the other person's work and goals, and a consistent pattern of contribution. These are the people whose careers you are actively tracking and whose problems you are thinking about. You make introductions for them without being asked, share opportunities that fit their goals, and follow up on things you know they are working through. These five relationships should include people in different professional circles from yours — ideally at different career levels and in different industries — to maximize their bridging value.

The 10 (Active Weak Ties): Ten contacts who receive lighter but regular maintenance — a relevant article shared occasionally, a genuine comment on their work, a note when something you encounter reminds you of their focus area. The investment is low enough that you can maintain it consistently; the consistency is what keeps the tie from going dormant. Many of the most valuable professional introductions come from this tier, because these are the people most likely to bridge to circles you do not directly touch.

The 20 (Dormant Tie Reactivations): Twenty contacts per year — roughly two per month — who receive a single genuine reconnection message. Not a pitch, not a request, just a sincere reintroduction: what you are currently working on, genuine acknowledgment of something you have noticed about their career trajectory, and an expression of interest in reconnecting. Burkus's research supports the specific design of this outreach: the goal is not to immediately extract value from the reconnection. It is to reactivate a relationship that already has trust built in — and to do so in a way that signals you are reaching out because you are genuinely interested in them, not because you need something.

Online vs. In-Person Networking: The Honest Tradeoffs

The research supports both online and in-person networking — they produce different outcomes and are most effective when understood as tools for different purposes rather than substitutes for each other. In-person networking at industry events, conferences, and local professional gatherings is highest-ROI for initial relationship formation: the combination of face-to-face context, ambient professional information, and shared experience creates relationship context faster than digital-only introductions. A thirty-minute conversation at an event moves a contact further along the relationship spectrum than several weeks of occasional LinkedIn interaction. The limitation is scale and geography — in-person opportunities are bounded by the events you can physically attend.

Online networking through LinkedIn, industry Slack communities, Twitter and other platforms optimized for professional discourse, and email is highest-ROI for relationship maintenance and for the give-first activities Grant's research supports — sharing expertise, making introductions, providing value in communities where your knowledge is relevant. Online platforms also make dormant tie reactivation frictionless: the barrier to sending a genuine reconnection message on LinkedIn is far lower than calling someone you have not spoken to in five years. The research-supported approach uses both: in-person for high-quality new relationship formation, online for the consistent give-first maintenance that keeps weak ties active and dormant ties warm over time.

One common mistake worth naming: treating LinkedIn connection count as a networking metric. The metric Granovetter's research supports is bridge quality — the number of distinct professional circles your network reaches — not total connection volume. Two hundred genuine weak ties spread across different industries, functions, and geographies produce more opportunity access than two thousand connections in your own professional bubble. Depth of network diversity beats breadth of same-circle density.

Quick Win — The Dormant Tie Reactivation Message

Today, identify three people you have not spoken to in two or more years who are doing work you find genuinely interesting. They do not need to be directly relevant to a current goal — the goal of this exercise is relationship reactivation, not extraction. Look at their LinkedIn profile or whatever professional presence they maintain. Notice what they are working on, what they have built, where they have moved.

Write each of them a message that does three things in three sentences or fewer:

1. Acknowledge the time gap: "It has been a long time since we talked" — no need to over-explain or apologize. Just acknowledge it briefly and warmly.
2. Reference something specific and genuine: "I noticed you have been building [X] / that you moved to [Y] / that your piece on [Z] made the rounds" — something that signals you are paying attention to their work, not just spamming an old contact list.
3. Express genuine interest with no ask: "I would genuinely love to catch up for 20 minutes and hear what you are working on" — or simply "Would be great to reconnect if you have time." No pitch. No favor request. Just a real human wanting to hear what another human is up to.

Burkus's research on dormant tie reactivation consistently finds that this kind of outreach — specific, warm, with no explicit ask — is received positively at a high rate, because the recipient already has a positive relationship context with you and because the message signals that you reached out because of genuine interest in them. This is the networking action with the highest return-to-effort ratio available to most people — and it requires nothing except three people you once knew and three honest sentences.
