INTRODUCTION

English translation pending.

CORE DEFINITION

Media dependency theory holds that audiences rely on mass media for information, interpretation, and reassurance, and that this reliance intensifies sharply during social conflict or rapid change. The core claim is that influence is proportional to dependence: when uncertainty is high and other institutions cannot explain events, people turn to media, and media gains leverage over cognition and behavior. The qualification is that dependence is asymmetric, giving the stronger party a bargaining advantage, and it varies with the range of alternatives available to the audience.

SCAFFOLDING EFFECT

Reduce cognitive load

- Crisis Amplifier: During pandemics or wars, media does not merely report reality but actively shapes it. - Source Choice: Deciding which outlets to trust directly determines how stable a society remains under stress. - Dependency Audit: Identifying which few channels you rely on reveals how exposed your worldview has become.

Dependence rises with social uncertainty and with how well media satisfy needs for information and orientation. The more turbulent the environment, the more people rely on media to explain events and guide action, and the greater media influence becomes. Because dependence is rarely symmetric, the party with fewer alternatives gains a bargaining advantage over the audience it serves.
