Revisiting Individual Choices in Group Settings: The Long and Winding (Less Traveled) Road
This study revisits Ariely and Levav's previous findings in relation to consumers' need for variety when ordering (food or beverages) in a group setting. We examine how group opinion and unanimity can explain consumers' individual choice in a group setting. We hypothesize that the relationship between individual choice and group opinion is nonmonotonic as it is moderated by the degree of unanimity around an alternative. We demonstrate this effect…
Social Networks and Diffusion: Avalanches and Links Evolution
Influence sociale et diffusion de l'innovation
The notion of diffusion holds a central place in any social system, because it is at the heart of individuals behaviour or representation phasing, hence of the co-ordination of their actions. The idea at the origin of the notion of diffusion is that inter-individual interactions are the driving forces of the evolution of individuals' behaviours, beliefs and represen-tations. Our approach in this paper is based on social influence networks. Agents…
Apprentissage social et diffusion de l'innovation: Réseaux critiques et intermédiarité
Le rôle des réseaux sociaux dans la diffusion de l'innovation demeure une question stratégique. Dans des travaux antérieurs, nous avons introduit un apprentissage relationnel, de type hebbien, qui conduit à un état critique, dans lequel certains agents acquièrent des positions, purement structurelles, de leaders d'opinion. Dans cet article, nous montrons que l'auto-organisation d'un réseau d'influence, par l'effet d'un apprentissage social, ne co…
