How We Keep Ratings Blind
The core mechanism of PressRank is the **blind taste test for news**. If voters know which channel said what, they vote based on their existing political leans and brand loyalties. By hiding the source until the ballot is cast, we measure content quality rather than brand marketing.
The Lifecycle of a Statement
Algorithmic Ingest
Statements are harvested programmatically from verified channels via public platform APIs (like the YouTube Data API). We do not accept free-floating, user-submitted quotes, which closes the main vector for targeted, malicious submissions.
Cryptographic Provenance Pinning
Every extracted excerpt is immediately hashed using SHA-256 upon entry. The content is pinned to its original source URL and transcript. This ensures no doctored quotes, deepfakes, or alterations can be injected into the voting pool.
Style Leakage Normalization
Outlets often have unique catchphrases, anchor signatures, or branded jargon that could de-anonymize a card. Our AI pipeline filters out these stylistic tells while retaining the surrounding context sentences so the excerpt remains fair and readable.
Balanced Slate Composition
Statements are randomized into slates of 6–8 (for top-k ranking) or 2 (for pairwise matchups). We enforce a constraint of **at most one statement per channel per slate**. This forces voters to make relative decisions between different outlets.
Post-Vote Reveal
Once you submit your ballot, the system records it blindly. You are then shown the reveal: which channels your selected statements actually came from. This provides immediate, transparent feedback and often surprises voters when their blind choices cross their partisan expectations.
Collusion & Triangulation
We double-check open crowd selections against an independent **AI referee analysis** and **public fact-checkers**. If the crowd's ratings on factual accuracy diverge sharply from verified databases, the system flags the coordinates as anomalous temporal surges, protecting the leaderboard from captured-audience takeovers.
