A single study showed that just changing the framing of a story (e.g., 'tax relief' vs. 'tax cut') can significantly alter how people support the policy, even when the underlying facts are identical.

Understanding Media Bias and Its Effect on Political Perception
Imagine looking through a camera lens. The lens focuses on some things and leaves others out of frame—that’s what media bias does. Every news outlet decides what to cover (agenda-setting) and how to present it (framing). These choices are often influenced by the outlet’s political leanings, commercial interests, or the desire to attract a particular audience. As a viewer, you don’t see the ‘whole picture’—you see the part the lens captures. Over time, this shapes what you think is important and how you feel about it.
A deeper explanation
Media bias works through several mechanisms. Agenda-setting tells us what to think about—by covering some issues more than others, outlets influence which topics we consider important. Framing goes a step further: it packages a story with a particular interpretation, using loaded words, images, and sources to suggest how we should evaluate it. This is reinforced by our own confirmation bias—we tend to seek out and remember information that matches our existing beliefs. The result is a feedback loop: biased media attracts likeminded audiences, who then demand more of the same, creating echo chambers where opinions are constantly reinforced and opposing views are rarely considered. This deepens political polarization and can distort our perception of reality, making it hard to find common ground.
