How Agenda Setting Detection Works
Agenda setting reveals which news sources drive the news cycle and which follow. Our AI tracks the timestamp of when each source first covers a story. Sources that consistently publish first are classified as agenda setters — they determine what becomes news. Sources that publish later are followers, picking up stories that others have already established.
Leader vs Follower Scores
Each source gets a leader score based on how often it publishes stories before others. A high leader score means the source frequently breaks news first. This metric changes over time and varies by topic — a source might lead on political news but follow on entertainment.
Story Adoption Patterns
We track how quickly other sources pick up stories originated by a particular outlet. Some stories spread within minutes; others take hours or days. This adoption velocity reveals which stories media considers important vs which it reluctantly covers.
Methodology: How Agenda-Setting Power Is Measured
Agenda-setting power captures how often a source breaks stories before other outlets. The system groups articles about the same event, identifies which source published first, and computes each source's ratio of first-mover stories to total stories covered. This produces a percentage that represents the source's agenda-setting power.
First Mover Identification
For each story cluster, we identify the source that published the earliest article. This source is labelled the "first mover" for that story. The timestamp used is the article's publication time as recorded in the source's RSS feed or website metadata. Sources that consistently appear as first movers across multiple story clusters are classified as agenda setters.
Agenda-Setting Power Score
The agenda-setting power percentage equals the number of stories where the source was the first mover divided by the total number of stories the source covered. A score of 30% or higher indicates a high-power agenda setter that frequently originates stories. Scores between 15% and 30% represent medium power. Scores below 15% suggest the source primarily follows stories that others break first.
Category Leadership
Beyond the overall power score, we track which categories each source leads in. A source might have low overall agenda-setting power but consistently break stories in a specific category like business or regional politics. The "top category led" field on each source card reveals this specialisation, helping you identify which outlets lead in the topics you care about most.
How to Interpret the Results
Reading the Bubble Chart
The bubble chart plots each source along two axes. The horizontal axis shows agenda-setting power (percentage of stories the source broke first). The vertical axis shows total stories covered (volume). Bubble size represents coverage volume. Green bubbles indicate high agenda-setting power (30%+), yellow indicates medium (15-30%), and red indicates low power. Sources in the upper right are high-volume agenda setters. Sources in the upper left are high-volume followers.
Setters vs Followers
The Agenda Setters panel lists sources that most frequently break stories first. These outlets drive the news cycle and influence what other media considers newsworthy. The Followers panel lists sources that primarily cover stories after others have published them. Being a follower is not inherently negative; many reputable sources invest in analysis and depth rather than speed. However, a source claiming to be a primary news outlet but consistently appearing as a follower may not be delivering on that promise.
