PAI measures public attention and visibility — how much the world is currently watching, reading, and talking about a person. It does not measure talent, achievement, or moral worth.
Overall public mindshare. Combines search interest, Wikipedia traffic, news coverage, social reach, conversation volume, and Wikipedia presence across languages.
Momentum right now. Measures spikes in Wikipedia pageviews, search interest, news velocity, and social conversation compared to recent baselines.
Sentiment is tracked separately and shown on person profiles. It is never used to calculate Popularity or Heat.

When a signal is unavailable, it is excluded from the denominator of the weighted average — it never pulls the score down. A person with 3 live signals scores as if those 3 signals are the full picture, rescaled to 100%.
Coverage score shows what fraction of signals were available. Scores with low coverage should be interpreted with caution.
| Coverage label | Threshold | Meaning |
|---|---|---|
| High coverage | ≥ 70% signals | Score is well-supported by available data |
| Partial coverage | 40–69% signals | Score is directionally correct but some signals are missing |
| Insufficient data | < 40% signals | Too few signals to form a reliable score |
All scores are tagged with a model version (currently v1). When the scoring formula changes, scores from different versions will not be compared to each other.
