Political Polarization Online by Ivy Silver

Political Polarization Online explores how digital platforms and algorithms contribute to increasing ideological divides. It examines how engagement-focused algorithms, designed to maximize user interaction, inadvertently foster echo chambers. These echo chambers amplify partisan content, reinforcing existing biases and hindering constructive dialogue. The book argues that these seemingly neutral algorithms systematically increase political division, challenging the idea that online platforms are simply neutral conduits of information.

The book is structured into three parts, beginning with an introduction to algorithmic amplification and its role in shaping online content consumption. It then explores the psychological mechanisms that drive individuals to seek out information confirming their beliefs. Finally, it delves into the real-world consequences of online political polarization, including its impact on electoral outcomes and democratic governance.

By combining quantitative data analysis with qualitative case studies, the book provides a comprehensive and accessible analysis of the complex relationship between technology and political polarization.
