How we score a headline

Not every headline carries the same weight, so we do not treat them as if it did. Each item that enters the EvAI pipeline is scored on a small set of independent signals, and the final number is a deliberate blend of them rather than a raw count of mentions.

The first signal is reach: how large and how credible the source is. A note buried in a niche feed and the same claim carried by a widely-followed outlet are not equivalent, and the score reflects that gap. The second is spread speed — how fast the item is being picked up and echoed elsewhere, which separates a story that is genuinely catching from one that simply exists. The third is freshness, a decay that lets recent activity dominate and lets stale interest fade on its own.

Combining the three keeps any single one from dominating. A loud source that no one repeats cools quickly; a modest source that spreads fast can still climb. The result is one attention score you can compare across the whole market, built from parts that each mean something on their own.
