Mass Communication and Journalism: Media Effects and Influence - Two-Step Flow Theory Lazarsfeld Berelson Gaudet Opinion Leaders

What It Is

The Two-Step Flow Theory, also known as the Opinion Leader Theory, was developed by Paul Lazarsfeld, Bernard Berelson, and Hazel Gaudet in 1944. This theory explains how information spreads through social networks, with opinion leaders playing a crucial role in influencing the opinions and behaviors of their followers. A classic example of this theory is the 1944 study on voting behavior in the presidential election, where Lazarsfeld and his team found that opinion leaders in Erie County, Ohio, significantly influenced the voting decisions of their acquaintances. This theory matters for media analysis as it highlights the importance of understanding how information is disseminated through social networks and how opinion leaders can shape public opinion.
