Un réexamen de la loi de Converse sur le lien entre le degré d'information politique et la mobilité de court terme de l'opinion

Abstract

AbstractThis study proposes an empirical test of a classical hypothesis formulated by Philip Converse about the link between political information and opinion change. The study departs from previous ones on three aspects: (1) it is conducted outside the electoral field; (2) political information—the key variable of the analysis—is directly measured and is issue specific, and (3) the test of Converse hypothesis is carried through the utilization of a quasi-experimental design. The results—based on a sample of students expressing opinions about the Canada-USA free trade agreement—exhibit the expected non-linear relation between the individual's level of political information and his propensity to change opinion. This conclusion suggests that particular groups could be more sensitive to political information flows.
