Impact of Popularity Indications on Readers' Selective Exposure to Online News

Selecting news online may differ from traditional news choices, as most formal importance indicators in traditional media do not convert directly to online news. However, online portals feature news recommendations based on collaborative filtering. To investigate how recommendations affect information choices, 93 participants browsed online news that featured explicit (average rating) or implicit (times viewed) recommendations or no recommendations (control group) while news exposure was logged. Participants picked more articles if the portal featured explicit recommendations, and stronger explicit recommendations instigated longer exposure to associated articles. Implicit recommendations produced a curvilinear effect with longer exposure for low and high numbers.
