Freshness, Credibility, and Diversity: How Dive Deeper Scores Every Source
A closer look at the three signals — beyond simple relevance — that shape which sources end up in a Dive Deeper report.
By Headlinne Editorial Team · Updated on
Freshness: recent coverage counts more
A source's score fades the older it gets, so a report naturally favors the latest reporting on a fast-moving story while still allowing older, foundational coverage to matter for background and history.
Credibility: publisher reputation, not popularity
Credibility reflects a publisher's track record — established wire services and specialist outlets score higher than unverified or low-quality sources. This is a starting signal, not a veto: even a highly credible source still needs to be relevant and add something new.
Diversity: avoiding an echo chamber of one outlet
A report built from ten articles that are all essentially the same wire story would look thorough but actually tell you very little. Diversity scoring rewards sources that add distinct information or a different angle, and caps how much any single outlet can contribute.
How the three combine with relevance
None of these signals works alone — a fresh, credible, diverse source still has to be genuinely relevant to the story to be cited. The four together are what produce a Sources section that is current, trustworthy, and varied all at once.
Why Headlinne screens sources this way
These three tests exist because a research tool that optimises only for relevance will happily build a confident report out of stale, thin, or one-sided material. Headlinne runs the freshness, credibility, and diversity checks on every Dive Deeper pass so the depth you get is not bought by lowering the bar on what counts as a source.

- ✓Freshness weights recent coverage more heavily without discarding useful older context.

Frequently asked questions
Does Dive Deeper use the same vetted sources as my Headlinne feed?
It starts there. Dive Deeper draws on Headlinne's own vetted publisher set first, then extends with live web search — and applies the same freshness, credibility, and diversity checks to anything it pulls in, so a report is never padded with whatever happened to rank highest.
Can an older article still be cited?
Yes — freshness lowers an older source's score but does not disqualify it. Historical and background sections often rely on older coverage precisely because it captures context a same-day story would not.
