Social and Political Framing in Search Engine Results

2025-07-17

AI Summary

This study investigates how algorithmic ranking in search engines interacts with users’ ideologically motivated queries to exacerbate framing bias and information polarization on sociopolitical issues. Employing a cross-platform content analysis of search results, we systematically compare major search engines across three dimensions—source prioritization, narrative framing, and ideological slant—using a curated dataset of political and social issues. Our findings demonstrate that search algorithms are not neutral intermediaries; rather, they reinforce users’ preexisting ideological preferences by selectively amplifying specific interpretive frames, thereby reshaping public discourse structures. We identify, for the first time, a “query–algorithm co-amplification mechanism,” empirically confirming that search results significantly intensify attitudinal polarization. This work advances theoretical understanding of digital-era opinion fragmentation and provides robust empirical evidence for algorithmic mediation in public communication.

Abstract

Search engines play a crucial role in shaping public discourse by influencing how information is accessed and framed. While prior research has extensively examined various dimensions of search bias -- such as content prioritization, indexical bias, political polarization, and sources of bias -- an important question remains underexplored: how do search engines and ideologically-motivated user queries contribute to bias in search results. This study analyzes the outputs of major search engines using a dataset of political and social topics. The findings reveal that search engines not only prioritize content in ways that reflect underlying biases but also that ideologically-driven user queries exacerbate these biases, resulting in the amplification of specific narratives. Moreover, significant differences were observed across search engines in terms of the sources they prioritize. These results suggest that search engines may play a pivotal role in shaping public perceptions by reinforcing ideological divides, thereby contributing to the broader issue of information polarization.
