Review signals

Review signal profile

How review-derived evidence enters the score — what was collected, what was filtered, and how it distributes across aspects. A signal profile, not an archive of individual reviews.

854 signals collected → 833 passed filters → 404 used in the current score.

A signal is one filtered data point — not one review, and not one person.

A signal profile — not a review archive. IndexFair does not host or republish individual reviews. We report how many signals were collected, how they were filtered, and how they distribute. The source platforms retain the original text.

What we don't publish. The exact filter thresholds resist gaming and stay internal. We disclose the categories and counts of what is set aside — never the rules that would let a bad actor tune around them.
