The Factual Score (1–10) rates the accuracy of verifiable factual claims — dates, statistics, quotes, attributions, and assertions that can be checked against trusted sources.
| Score | Meaning |
|---|---|
| 8–10 | Mostly or fully accurate — claims verified by credible sources |
| 4–7 | Mixed accuracy — some claims accurate, some questionable or false |
| 1–3 | Mostly or entirely inaccurate — significant false claims identified |
The Context Score (1–10) rates whether the article gives you the full picture — framing, omitted context, cherry-picked data, and one-sided presentation.
| Score | Meaning |
|---|---|
| 8–10 | Balanced and complete — fair framing, no significant omissions |
| 4–7 | Notable omissions or framing issues that affect interpretation |
| 1–3 | Highly misleading framing or major context omitted |
