Why Partisan Media Deepen Political Extremes—and These Effects Last Days After

New research explores how partisan media outlets amplify viewers' political polarization. Using experimental methods and data analysis, it demonstrates that exposure to partisan content strengthens extreme viewpoints among citizens—even days afterward.

Experimental Findings:

• Partisan media effectively mobilizes motivated reasoning in its audience
• Polarization effects persist for several days after initial exposure
• The research shows minimal viewership still produces significant political impacts across the broader public arena
