The lead story is chosen by a fully deterministic score -
coverage × diversity × recency × novelty
× toll - with nothing chosen by hand on the day.
Diversity (spread across countries
and the political spectrum) carries the most weight, so a
story that everyone agrees is big rises above one that is simply
being shouted loudest in a single country's press.
Each dimension below scores from 0 to 1 (higher is stronger), but they don't count equally: each is raised to the weight shown, then the weighted dimensions combine to rank the day's stories - so this story comes out top across the combination today.
How many distinct outlets are running the story - log-scaled, so 20 isn't worth twice 10.
How widely that coverage is spread across countries and the political spectrum - weighted heaviest, so a story merely loud in one bloc doesn't dominate.
Favours stories with fresh, recent coverage over ones already fading (measured from the average time the coverage was published).
Penalises a story that already led on a recent day, easing back over ~4 days, so a repeat must bring bigger coverage to lead again.
Whether the reporting says people were harmed, and how many, read from the headlines themselves and log-scaled. Never zero: it breaks ties rather than deciding.
