Chapter 19 Exercises: Weak Ties and the Hidden Power of Loose Connections

Level 1 — Comprehension and Recall

These exercises test your understanding of the chapter's core concepts.

1. Define "weak tie" using Granovetter's four-dimensional definition. Give one example of a weak tie and one example of a strong tie from your own life.

2. What was the core finding of Granovetter's 1973 study about how people find jobs? Describe the sample he used and the method he used to measure tie strength.

3. Explain the "clustering problem" with strong ties. Why does a network composed primarily of strong ties carry less novel information than one with diverse weak ties?

4. What is a "local bridge" in network terms? Why are local bridges almost always weak ties rather than strong ones?

5. The chapter identifies three mechanisms by which weak ties carry more novel information than strong ties. Name and briefly explain all three.

Level 2 — Application and Analysis

These exercises ask you to apply chapter concepts to new situations.

6. Priya's breakthrough came through a weak tie — Professor Adichie — rather than through her close friends. Analyze this outcome using the Granovetter framework. What specifically did the weak tie provide that Priya's strong ties couldn't? What properties of Professor Adichie's position in the network made her valuable?

7. Map your own immediate network as best you can. Identify: (a) your three strongest ties, (b) your most diverse weak ties (the acquaintances who move in the most different circles from your own), and (c) any "local bridges" — people who connect you to clusters you couldn't otherwise access. What do you notice?

8. LinkedIn's 2022 study found that weak tie referrals tended to result in higher-paying jobs than strong tie referrals. Generate at least two hypotheses about why this might be true. Which hypothesis do you find most persuasive, and why?

9. "Dormant ties" are connections that were once stronger but have gone quiet. Identify three dormant ties in your own network — people you knew in a different context and haven't spoken to recently. Why are dormant ties potentially valuable? What would reactivating them cost?

10. The chapter says that "the diversity of your weak tie network determines the breadth of opportunity you can access." Design a concrete plan for expanding your weak tie network over the next 90 days. What contexts would you enter? What specific actions would you take? What would you signal about what you need?

Level 3 — Research and Evidence Evaluation

These exercises ask you to engage with evidence and research methods.

11. Granovetter's original study was conducted in Newton, Massachusetts, with predominantly white, male, professional men. How might the weak tie effect operate differently for: (a) women in male-dominated industries, (b) first-generation professionals, (c) people from racial minority groups in predominantly white industries? What research would you want to see conducted?

12. The 2022 LinkedIn/MIT/Harvard study analyzed 20 million users. List at least three ways that LinkedIn users might differ from the general population of job seekers in ways that could affect the study's external validity. Does this undermine the study's conclusions? Why or why not?

13. The chapter distinguishes between "ambient awareness" (passive awareness of a weak tie's activity on social media) and active relationship maintenance. Design a study that would test whether ambient awareness alone is sufficient to keep weak ties warm enough to produce information-sharing when needed. What would you measure? What would be your experimental design?

14. Adam Grant's research on "giving networks" suggests that information-sharers receive more information back over time. Is this finding consistent with Granovetter's framework? Can you imagine situations where it might not hold? What confounding variables might affect the relationship between information-giving and information-receiving in weak tie networks?

15. The chapter claims that the weak tie effect is especially strong in periods of economic recovery (when new jobs are being created). What mechanism would explain this? Design an analysis using publicly available data (LinkedIn job postings, Bureau of Labor Statistics) that would test this hypothesis.

Level 4 — Synthesis and Critical Thinking

These exercises require you to integrate multiple ideas and form original arguments.

16. Chapter 18 argued that structural luck operates through social networks — that those born with better social capital have access to better opportunity flows. Chapter 19 shows that weak ties are the primary channel for opportunity. How do these two chapters interact? Does the weak tie framework help close the structural luck gap, or does it partially reproduce it? (Consider: who has the easiest access to diverse weak ties?)

17. The chapter suggests that introverts can build effective weak tie networks through asynchronous, written communication. But some research suggests that in-person interaction creates stronger social bonds than digital interaction. Write a 400-word analysis of the tradeoffs: what do digital weak ties gain and lose compared to in-person weak ties? What practical implications follow?

18. Granovetter's paper was published in 1973. The internet didn't exist yet. LinkedIn launched in 2003. Write a 500-word analysis of how Granovetter's theory needs to be updated for the digital age. What changes? What stays the same? Are there new categories of tie strength that Granovetter didn't anticipate?

19. The chapter says that "the easiest weak ties form around shared specific interests — not 'networking' in the abstract but participation in communities of practice." Evaluate the difference between networking and community participation as weak tie strategies. What does each optimize for? In what contexts is each more appropriate?

20. Imagine you are advising Priya on her complete job search strategy, incorporating the insights from both Chapter 18 (structural luck) and Chapter 19 (weak ties). Write a 600-word strategic memo that: (a) identifies the structural factors working against her, (b) explains why her initial strategy (formal applications) was suboptimal, (c) outlines a revised weak-tie-centered strategy, and (d) identifies the key risks and limitations of the new approach.

Level 5 — Creative and Integrative Projects

These exercises ask for original creative or research work.

21. The Weak Tie Mapping Project. Create a visual map of your professional and quasi-professional network. Use circles of different sizes to represent tie strength (larger = stronger). Draw connections and note the industry or domain of each connection. Identify: (a) your densest cluster, (b) your most isolated node (a weak tie who doesn't connect to anyone else in your map), (c) the gaps in your map where you wish you had connections. Write a 300-word reflection on what you see.

22. The 30-Day Weak Tie Activation. Over 30 days, make at least one weak tie activation per week — a genuine, specific, low-cost contact with a dormant or weak tie. This could be an email, a LinkedIn comment, a forwarded article. Document: who you contacted, what you said, what happened. At the end of 30 days, write a 400-word reflection on what you learned about the responsiveness of weak ties to low-cost activation.

23. Read the original Granovetter (1973) paper in full (it is publicly available). Write a 500-word critical summary that covers: (a) the research question, (b) the methodology, (c) the key findings, (d) one significant limitation, and (e) why the paper has remained influential for 50+ years.

24. Interview three people who have recently made a significant career change or gotten a new job. Ask each of them: Did you find the opportunity through a formal listing, a close contact, or an acquaintance? If through a contact, how strong was that tie? Document and compare your findings to Granovetter's. Do your three cases support his theory?

25. The chapter mentions that the weak tie effect may be especially strong in dynamic economic periods when new jobs are being created. Using the Bureau of Labor Statistics JOLTS data (publicly available online) and your own analysis, identify a recent period of high job creation and a period of low job creation. Write a 400-word analysis of what the Granovetter framework would predict about weak tie value in each period, and what practical advice follows for someone job-searching in the current market.
