The strength of weak ties is that they tend to be long—they connect socially distant locations, allowing information to diffuse rapidly. The authors test whether this “strength of weak ties” generalizes from simple to complex contagions. Complex contagions require social affirmation from multiple sources. Examples include the spread of high‐risk social movements, avant garde fashions, and unproven technologies. Results show that as adoption thresholds increase, long ties can impede diffusion… 
Failure in Complex Social Networks
TLDR
It is shown that scale-free networks are much less robust than exponential networks for the spread of complex contagions, which highlights the value of more homogenously distributed social networks forThe robust transmission of collective behavior.
Complex Contagions and the Diffusion of Innovations: Evidence from a Small-N Study
The recent literature on “complex contagions” challenges Granovetter’s classic hypothesis on the strength of weak ties and argues that, when the actors’ choice requires reinforcement from several
The weakness of weak ties for novel information diffusion
TLDR
It is demonstrated that hesitation to share across weak links substantially impedes overall diffusion, and it is shown that the addition of weak ties to a social network can strictly reduce the extent and speed of information diffusion.
Complex contagion and the weakness of long ties in social networks: revisited
TLDR
Three small world models are studied and rigorous analysis on the diffusion speed of a k-complex contagion, in which a node becomes active only when at least k of its neighbors are active, showing that compared to simple contagions, weak ties are not as effective in spreading complex contagions due to the lack of simultaneous active contacts.
Long ties accelerate noisy threshold-based contagions
TLDR
This revised conclusion suggests that those wanting to increase spread should induce formation of long ties, rather than triad-closing ties, in order to ensure that random rewiring accelerates spread.
Effects of Opposition on the Diffusion of Complex Contagions in Social Networks: An Empirical Study
TLDR
The empirical results point out how network structure and opposing perspectives can alter the widespread adoption of social behaviors that can be modeled as complex contagions.
Complex Contagions: A Decade in Review
TLDR
Recent advancements in applied studies of complex contagions, particularly in the domains of health, innovation diffusion, social media, and politics are discussed, including both diversity of demographic profiles among local peers and the broader notion of structural diversity within a network.
Long-distance diffusion and strongly tied bridges: The influence of the originator’s network
Network researchers have viewed a few influential individuals as driving the diffusion of ideas among individuals while paying little attention to the ways by which diffusion events came about in the
Structural diversity in social contagion
TLDR
This analysis of the growth of Facebook shows how data at the size and resolution of the Facebook network make possible the identification of subtle structural signals that go undetected at smaller scales yet hold pivotal predictive roles for the outcomes of social processes.

TLDR
It is shown that heterogeneity plays an ambiguous role in determining a system's stability: increasingly heterogeneous thresholds make the system more vulnerable to global cascades; but anincreasingly heterogeneous degree distribution makes it less vulnerable.
