What is decision velocity?

Decision velocity is a concept in personal epistemology: Sometimes deciding fast is more important than deciding optimally.

Example: You're choosing between two cloud providers for a new microservice. You've spent three weeks evaluating benchmarks, reading case studies, and requesting demos. Meanwhile, the team that needed the service has built a workaround, the market window has narrowed, and the cost of the evaluation itself now exceeds the cost difference between the two options. The decision wasn't wrong — the speed was. A 70% confidence pick on day two, deployed with a migration path, would have delivered value for nineteen days while you were still comparing dashboards.

This concept is part of Phase 23 (Decision Frameworks) in the How to Think curriculum, which builds the epistemic infrastructure for decision frameworks.
