BOOKMAKER PSYCHOLOGY
The conceptual spine of WagerBird's educational positioning. Most bettors believe sportsbooks try to balance action; modern books are sophisticated market makers who shape lines around expected behavior. This pathway works through the framework end to end: how books actually price, why public bias is structural, what line movement reveals, the anatomy of a trap line, sharp markets vs retail markets, the strategic pricing of key numbers, why most bettors lose, the institutional approach, and the capstone synthesis on how to think about any line.

Reading line movement
Lines move all day. Most movement is noise. The signal lives in a small set of patterns: who moved first, what direction relative to public flow, what limits look like, and how the move propagates across books. The framework that distinguishes information from volume.
