The Media Shape Public Opinion

Since the era of print newspapers, information has been disseminated on a large scale, later amplified by radio, television, and then social media. This evolution highlights the central role of media in shaping collective representations and in how individuals perceive the world.

This influence is expressed through several mechanisms: media prioritize public issues, shape the perception of events, and frame certain problems within specific interpretative frameworks. As a result, media agenda and political agenda appear closely interconnected.

With the rise of the internet, the public sphere has been transformed: echo chambers, information bubbles, and content homogenization can reinforce pre-existing opinions, and sometimes even foster radicalization dynamics. Fake news and deepfakes further intensify these trends.

Consequently, a tension emerges between protecting public debate and respecting freedom of expression, particularly in the context of sometimes opaque algorithms. In this setting, how do media actually shape our opinions? And what role should citizens play in this transformed information space?
