## Statement

Major platforms' engagement-optimized ranking systems disproportionately surface content that triggers anger and out-group hostility, accelerating affective polarization and information fragmentation through repeated exposure to the most divisive subset of public speech.

## Causal links

- moderates → [M1: Information environment fragmentation](https://aboard.untype.me/claims/M1/index.md) (strength 0.55) — Engagement-ranked feeds accelerate partisan information sorting, deepening fragmentation of the news-source mix.
- moderates → [M2: Affective polarization erodes democratic norms](https://aboard.untype.me/claims/M2/index.md) (strength 0.50) — Outrage amplification compounds out-group hostility through repeated platform exposure, raising affective polarization at scale.
- reduces ← [L3: Platform antitrust + algorithmic transparency](https://aboard.untype.me/claims/L3/index.md) (strength 0.40) — Mandatory audits and antitrust enforcement reduce the dominance of any single engagement-ranking system over public discourse.

## Forecasts

- **F4** (resolves 2027-12-31): Will at least one major platform (Meta family, X, TikTok, YouTube) publicly publish algorithmic-ranking parameters or detailed audits by 2027? — P=0.41 across 6 models, spread 0.30 _Superseded, replaced by F7._
- **F7** (resolves 2027-03-31): Will fully automated decisions exceed 50% of statements of reasons submitted to the DSA Transparency Database for calendar 2026? — P=0.57 across 3 models, spread 0.46
