# Non-Fiction Patterns **Chapter template**: Hook(empathy) → Problem(why it matters) → Evidence(proof) → Framework(solution model) → Application(concrete examples) → Summary(3 points + bridge). **Learner levels**: Novice ("Why?" · analogies) → Competent ("How?" · real scenarios) → Expert (root causes · edge cases). **Evidence hierarchy** (high→low): Research(peer-reviewed) → Data(statistics) → Case Study(3+) → Experience(post-mortems) → Anecdote(empathy only). Core claims require Data+. **Argument**: Claim(what) + Warrant(why valid) + Impact(so what). Strong = Claim + multiple Warrants + specific Impact. **Callouts** (≤3/chapter): Tip · Warning · Example · Exercise. **Difficulty gradient**: ▁▂▃ Intro → ▃▄▅ Basics → ▅▆▇ Practice → ▇▇██ Advanced. First chapter of each part slightly easier than last of previous.
