The Wisdom of the Network: How Adaptive Networks Promote Collective Intelligence
Abdullah Almaatouq, Alejandro Noriega-Campero, Abdulrahman Alotaibi +3
Social networks continuously change as new ties are created and existing ones fade. It is widely noted that our social embedding exerts a strong influence on what information we re…
Reach and speed of judgment propagation in the laboratory
Mehdi Moussaid, Stefan Herzog, Juliane Kammer +1
In recent years, a large body of research has demonstrated that judgments and behaviors can propagate from person to person. Phenomena as diverse as political mobilization, health…
Patterns of cooperation during collective emergencies in the help-or-escape social dilemma
Mehdi Moussaid, Mareike Trauernicht
Although cooperation is central to the organisation of many social systems, relatively little is known about cooperation in situations of collective emergency. When groups of peopl…
Crowd Behaviour during High-Stress Evacuations in an Immersive Virtual Environment
Mehdi Moussaïd, Mubbasir Kapadia, Tyler Thrash +4
Understanding the collective dynamics of crowd movements during stressful emergency situations is central to reducing the risk of deadly crowd disasters. Yet, their systematic expe…
The amplification of risk in experimental diffusion chains
Mehdi Moussaid, Henry Brighton, Wolfgang Gaissmaier
Understanding how people form and revise their perception of risk is central to designing efficient risk communication methods, eliciting risk awareness, and avoiding unnecessary a…
Opinion Formation and the Collective Dynamics of Risk Perception
Mehdi Moussaid
The formation of collective opinion is a complex phenomenon that results from the combined effects of mass media exposure and social influence between individuals. The present work…
Social Influence and the Collective Dynamics of Opinion Formation
Mehdi Moussaid, Juliane E. Kaemmer, Pantelis P. Analytis +1
Social influence is the process by which individuals adapt their opinion, revise their beliefs, or change their behavior as a result of social interactions with other people. In ou…
A hierarchy of heuristic-based models of crowd dynamics
Pierre Degond, Cécile Appert-Rolland, Mehdi Moussaid +2
We derive a hierarchy of kinetic and macroscopic models from a noisy variant of the heuristic behavioral Individual-Based Model of Moussaid et al, PNAS 2011, where the pedestrians…
Traffic Instabilities in Self-Organized Pedestrian Crowds
Mehdi Moussaid, Elsa G. Guillot, Mathieu Moreau +7
In human crowds as well as in many animal societies, local interactions among individuals often give rise to self-organized collective organizations that offer functional benefits…
How simple rules determine pedestrian behavior and crowd disasters
Mehdi Moussaid, Dirk Helbing, Guy Theraulaz
With the increasing size and frequency of mass events, the study of crowd disasters and the simulation of pedestrian flows have become important research areas. Yet, even successfu…
Collective Information Processing and Pattern Formation in swarms, flocks and crowds
Mehdi Moussaid, Simon Garnier, Guy Theraulaz +1
The spontaneous organization of collective activities in animal groups and societies has attracted a considerable amount of attention over the last decade. This kind of coordinatio…
The walking behaviour of pedestrian social groups and its impact on crowd dynamics
Mehdi Moussaid, Niriaska Perozo, Simon Garnier +2
Human crowd motion is mainly driven by self-organized processes based on local interactions among pedestrians. While most studies of crowd behavior consider only interactions among…
An individual-based model of collective attention
Mehdi Moussaid, Dirk Helbing, Guy Theraulaz
In our modern society, people are daily confronted with an increasing amount of information of any kind. As a consequence, the attention capacities and processing abilities of indi…
Experimental study of the behavioural mechanisms underlying self-organization in human crowds
Mehdi Moussaid, Dirk Helbing, Simon Garnier +3
In animal societies as well as in human crowds, many observed collective behaviours result from self-organized processes based on local interactions among individuals. However, mod…
