Checklist Discipline

Use checklists to prevent investment oversights. Without process, there is no reliable feedback loop. Structured execution and review improve decision quality over time. Run a decision loop of research, thesis, execution, and post-mortem; document assumptions and update playbooks with evidence, not hindsight bias. Carl Icahn advocates a repeatable process: define criteria, execute consistently, and review decisions against evidence. Process quality drives outcome consistency. Key insight: Checklists enforce discipline and prevent errors. A process is like a pilot checklist: discipline prevents simple mistakes when pressure rises and keeps outcomes more repeatable.

Avoid misuse: Having opinions without execution criteria
