Political Gatekeeping
Many modern political institutions follow a chain of command in which first-stage players (such as chief executives in presidential systems and/ or prime ministers in parliamentary governments) have a procedural-right to hinder second-stage players from participating in collective choice; this is known as Political Gatekeeping. Gatekeeping practices include attaching riders (provisions) to bills and the House's ability to enforce rules that expedite consideration of otherwise blocked legislation, as in the case of combatting a filibuster. Political Gatekeeping also manifests in the form of selective candidacy, where established officials select which candidates promote their own hand-picked candidates and restrict resources/support for unwelcome candidates.

Gatekeeping found in Social Media
Some fear that modern social media content has become increasingly monitored and gatekept, which in turn has allowed for agendas to be pushed, weakening the role of the fourth estate. This can prove to be quite dangerous, as an audience's selective exposure to certain news media can skew perceptions, lessen the diversity of ideals and reinforce prejudices.
