 ## What Makes This Different
 
 **Evidence is the filter — including knowing what to exclude.**
-Every skill is grounded in named research: specific authors, specific studies, specific findings. Frameworks that lack empirical support — including learning styles, VAK, and other widely-circulated but poorly-evidenced approaches — are not included. The library documents exactly what was excluded and why in [EXCLUSIONS.md](EXCLUSIONS.md). For any school or faculty trying to separate evidence from convention, that document is worth reading on its own.
