Social Network Mechanisms – serie

Conspiracy theories are as old as society^—^but never have they spread so fast or so visibly. In an age of social media, moments of crisis and conflict ignite waves of conspiratorial storytelling that reshape how people interpret events, assign blame, and mobilize action.Ctrl+Alt+Doubt offers a new way to understand why conspiracy theories grow and persist. Rather than treating them as cognitive errors, psychological pathologies, or products of echo chambers, Rao and Greve analyze conspiracy theories as linguistic constructions^—^stories built from recognizable semantic patterns. Using tools from distributional semantics, they map the semantic space of conspiracy talk and show how meanings are assembled, recombined, and diffused online.Drawing on cases from COVID-19 and the Black Lives Matter protests, Rao and Greve show that conspiracy theorizing is a form of bricolage: people tinker with cultural fragments to craft explanations that reduce uncertainty and threat. New conspiracy beliefs are most likely to take hold when they are linguistically close to beliefs people already hold. The book traces how conspiracy theories spread through superspreaders, fear-laden language, bots, and shared hashtags^—^revealing conspiracy theorizing as a form of proto-coordination that generates community, amplifies outrage, and enables collective sensemaking among opponents of social movements.By foregrounding language and interaction, Ctrl+Alt+Doubt bridges cultural sociology, computational linguistics, and diffusion theory^—^offering a powerful framework for understanding how conspiracy theories spread and how interventions might be designed to blunt their social harm.

The Renaissance in Florence was not only a time of extraordinary artistic and philosophical creativity; it also marked a pivotal moment in the invention of new organizational forms that reshaped the city's economic, political, and social life. In Organizational Invention in Renaissance Florence, John F. Padgett distills and synthesizes thirty years of research into how Florentine institutions and social networks developed and transformed over two centuries. Drawing on an unparalleled historical dataset encompassing more than 100,000 individuals, Padgett maps the intricate web of relationships that connected Florence's families, businesses, and political actors between 1300 and 1500.The book centers on three major arenas of organizational change. First, Padgett traces the evolution of business structures, particularly within the banking sector, focusing on the development of the diversified partnership-system form of business organization. Second, he examines the shifts to Florentine kinship networks, Florentine kinship networks, outlining the formation of patrilineage and its diffusion from upper classes to middle classes. Finally, he charts the shifting terrain of political networks and the transformation of oligarchic elites. Across all three domains, Padgett demonstrates that organizational change did not occur in isolation. Instead, developments in one arena continually spilled over into others through the dense, cross-cutting social networks that underpinned Florentine society. Elites were rarely confined to a single role: they were merchants, bankers, politicians, and civic leaders simultaneously, moving fluidly among spheres as circumstances shifted. This multivalent identity, he argues, was central to Florence's adaptability and resilience. Organizational Invention in Renaissance Florence ultimately offers a fresh interpretation of the Renaissance, revealing how social networks emerged, transformed, and generated new forms of collective life during a period of intense social, political, and cultural change.

Both scholars and decision-makers recognize that the functioning of an organization is the result of a complex interplay between purposively designed elements, such as structures and processes, and emergent elements, like the informal networks of relationships that connect individuals and groups. Despite this widely shared awareness, scientific knowledge on this relationship and its translation into coherent models and principles of organizational design remain fragmented and unstructured.This book adopts a network perspective that conceptualizes organizational structure as a landscape of interconnected networks composed of actors' interactions and relationships. Some of these networks are intentionally designed, grounded in formal structures, processes, and workflows. Others emerge informally, shaped by instrumental and expressive social ties. Together, they constitute the relational infrastructure through which actors coordinate and access key resources, including information, knowledge, and social or political support.Drawing on empirical studies conducted across diverse organizational contexts, the book develops a unified theory and methodology for interpreting and understanding the complex relationship between formal organizational structures and informal social networks, how they shape one another, evolve together, and jointly influence organizational outcomes

Strong Bridges is a book about a contradiction and the opportunity it offers. For decades, social network theory has drawn its maps of advantage from the idea that brokers sit astride structural holes, reaping value from weak ties that bridge disconnected worlds. But what if some of those bridges are not weak? What if the real advantage lies not just in structure, but in trust forged in interpersonal history regardless of structure? This is the puzzle Strong Bridges takes up. It begins with guanxi, the colloquial Chinese term for relationship advantage, often dismissed as cultural peculiarity or corruption. But the authors treat guanxi as a strategic research site, not a cultural relic. They view it a niche-word pointing to a broader category of human experience. Combining analytic rigor with quality network data, they pull apart the Siamese twins of tie strength and network structure, documenting the prevalence and competitive value of high-trust ties that span structural holes, i.e., strong bridges. The book offers two discovery stories; one empirical, one theoretical. The first tracks how guanxi bridges operate in the personal networks of Chinese entrepreneurs. The second reshapes core assumptions in network theory. Across industries, events, and even a pandemic, strong bridges emerge as resilient assets distinct from embedded ties, more predictive of cooperation, and more durable than theory currently expects. This is a book about the anatomy of network advantage. It reframes brokerage not as a fragile position, but as a relationship earned, remembered, and surprisingly strong.
