Résumé

Nous proposons un modèle visant à reproduire le processus de formation d'opinions, modèle qui incorpore le concept d'affinité relative parmi les agents. L'opinion et l'affinité évoluent de façon auto-consistante, et offrent une interaction non triviale. Une transition continue a été déterminée entre une phase cohérente, où la population présente toute la même opinion, et une phase désordonné avec plusieurs groups d'opinion. Indicateurs d'un comportement "critique" ont aussi été détectés. Nous présentons une riche phénoménologie liée aux implications psychologiques.
