Echo chambers online?: Politically motivated selective exposure among Internet news users1

A review of research suggests that the desire for opinion reinforcement may play a more important role in shaping individuals’ exposure to online political information than an aversion to opinion challenge. The article tests this idea using data collected via a web‐administered behavior‐tracking study with subjects recruited from the readership of 2 partisan online news sites (N = 727). The results demonstrate that opinion‐reinforcing information promotes news story exposure while opinion‐challenging information makes exposure only marginally less likely. The influence of both factors is modest, but opinion‐reinforcing information is a more important predictor. Having decided to view a news story, evidence of an aversion to opinion challenges disappears: There is no evidence that individuals abandon news stories that contain information with which they disagree. Implications and directions for future research are discussed.
