Abstract

Global debate over the impact of algorithms and search on shaping political opinions has increased following dramatic election results in Europe and the US. Powerful images of the Internet enabling access to a global treasure trove of information have shifted to worries over whether those who use search engines and social media are being fed inaccurate, false, or politically targeted information that distorts public opinion. There are serious questions over whether biases embedded in the algorithms that drive search engines and social media have major political consequences, such as creating filter bubbles or echo chambers. For example, do search engines and social media provide people with information that aligns with their beliefs and opinions or do they challenge them to consider countervailing perspectives? Most generally, the predominant concern is do these media have a major impact on public opinion and political viewpoints, and if so, for the better or worse.

This study addresses these issues by asking Internet users how they use search, social media, and other important media to get information about political candidates, issues, and politics generally, as well as what difference it makes for individuals participating in democratic processes. We conducted an online survey of Internet users in seven nations: Britain, France, Germany, Italy, Poland, Spain, and the US.
