For this Leibniz Media Lecture, we welcome Professor Olaf Jandura from the D\u00fcsseldorf University of Applied Sciences. In his presentation, he will examine the dynamics of ideological polarization by combining research on polarization with research on social milieus. The Hamburg section of the Research Institute Social Cohesion (RISC)<\/a> is hosting this Leibniz Media Lecture.<\/p>\n

Moderator: Dr. Lisa Merten<\/a><\/p>\n

The presentation “Milieuspezifische Perspektiven auf die Polarisierungsthese<\/span>” [Milieu-Specific Perspectives on the Polarization Hypothesis] will be held in German.<\/p>\n

About the Presentation<\/h2>\n

This presentation is based on a three-wave trend survey conducted from 2020 to 2024. It examines how ideological divides between political-communicative milieus have evolved, as well as the role of media use in this process. The findings do not reveal a simple division of society into two camps but rather a growing differentiation at the political fringes. The proportion of isolated and self-isolating fringe milieus is rising significantly, while integrated milieus in the political center are losing influence. Using migration and climate change as examples, the study highlights divides between social welfare\u2013oriented liberal milieus and market liberal\u2013authoritarian milieus. Selective media use and homogeneous conversation networks appear to amplify these developments.<\/p>\n
