Sylvain Delouvée, Pourquoi faisons-nous des choses stupides ou irrationnelles ?

Publié par , le 14 novembre 2011

Attirée par le titre, tel un papillon par une ampoule allumée, j’y ai trouvé un contenu à la hauteur de mes espérances. Vous n’apprendrez sans doute pas grand-chose si vous êtes coutumier des livres de psychologie sociale, mais vous vous surprendrez à sourire en découvrant les dessins et les petites anecdotes amusantes généralement passées sous silence, car n’apportant rien à la compréhension de ces expériences devenues de grands classiques.

Si la psychologie sociale n’est qu’une notion relativement nébuleuse pour vous, je vous invite cordialement à allier la découverte à l’amusement grâce à cet ouvrage. Parce que vous saurez enfin comment établir des normes collectives, faire paniquer les masses, introduire des rumeurs dans la pensée sociale, utiliser la tendance au conformisme présente en chacun de nous, provoquer une guerre ouverte entre deux groupes et ensuite apaiser le conflit quand ça ne sera plus drôle, continuer à diriger votre secte après avoir fourni une mauvaise prédiction, soumettre autrui à votre autorité et tout un tas d’autres choses qu’il vous faudra découvrir par vous-même parce que c’est nettement plus savoureux.

Il y a de fortes chances pour que vous soyez étonné, interloqué, voire incrédule, mais, rassurez-vous, les résultats obtenus ont souvent fait cet effet aux instigateurs des expériences qui étaient bien loin de s’attendre à de telles observations.

Finalement, rien de stupide ou d’irrationnel. Il s’agit d’apprendre à déchiffrer les comportements sociaux humains.
