GNews / yfinance / News Aggregation
OPEN
The call: Source-bias audit: Google News and Yahoo Finance are the engine's primary news and market feeds, with Google-curated ranking and surface-level market data as structural biases.
What happened: Mitigation stated (non-Google RSS feeds, the pipeline's own short-volume data); no outcome to score.
A source-bias audit of the engine's news and market data: Google controls what Google News surfaces and has its own conflicts of interest, well-resourced outlets dominate through search optimization, Yahoo Finance data misses dark-pool trading (~40% of US equity volume), and stories that were killed or self-censored are invisible. Partial mitigation comes from non-Google RSS feeds and the engine's own FINRA short-volume data.
The engine's record — word for word
**Source bias audit.** GNews (Google News) and yfinance (Yahoo Finance) are the engine's primary news and market data sources. Core biases: (1) Google controls ranking and visibility — GNews results are Google-curated. Google's own interests (Alphabet is a PCAST-adjacent company, DeepMind is a frontier AI lab, Google Cloud competes for the same contracts the engine tracks) create structural conflicts. Stories critical of Google/Alphabet may be deprioritized. (2) SEO gaming — GNews results are shaped by search engine optimization, meaning well-resourced outlets (often Big Three-owned media companies) dominate over independent sources. (3) yfinance reports market data 'as reported' by exchanges — it does not account for dark pool activity (~40% of US equity volume), fails-to-deliver, or the short volume data the engine's own pipeline tracks separately. (4) Survivorship bias — GNews surfaces stories that got published. The stories that were killed, delayed, or self-censored are invisible. **Mitigation:** The engine's RSS feeds (Al Jazeera, Ars Technica) provide partial non-Google perspectives. The pipeline's own FINRA short volume data bypasses yfinance's surface-level reporting.
