According to its mission statement “… Facebook’s mission is to give people the power to share and make the world more open and connected…” In this aim, Facebook’s engineers manage people’s home page feed (newsfeed) so that voters see things they like and stay longer. For example, if a voter is interested in politics will show posts by their friends that support their political views but repress those that would clash \cite{Keegan2016}. Why is this a problem? By only showing views that users are likely to agree with, they are sheltered from new ideas. They end up trapped in an echo chamber listening only to the similar.
