Watching sentimental films can have a greater influence on a person’s political opinions than advertising or news reports, according to new research.
Viewers who are “not prepared” to be critical about what they are seeing on screen were more likely to experience a “leftward shift” in attitudes when watching Hollywood movies with an underlying liberal message.
A team of political scientists at the University of Notre Dame in Indiana set out to explore the power of political messages in popular films, and found that they “possess the ability to change attitudes, especially on issues that are unframed by the media”.
