The Evidence-Based Life

Every rule answers two fundamental questions: What does it cost, and what does it return?

Beneficiaries are tiered by return likelihood: 1. You directly; 2. Spouse and direct family; 3. Friends and colleagues; 4. Strangers (where liability and risk must be weighed alongside aid).

You don't need to do everything: this is a prioritized catalog, not an exhaustive checklist. Select one or two rules that matter to your situation. Dotted cross-references can be clicked to preview the referenced rule immediately.
