Question
What is fast frugal heuristics?
Quick Answer
Agents for recurring decision types like buy-versus-build or accept-versus-decline.
Fast frugal heuristics is a concept in personal epistemology: Agents for recurring decision types like buy-versus-build or accept-versus-decline.
Example: You get a freelance inquiry every few weeks. Each time, you agonize: Is the rate high enough? Do I have capacity? Does the work align with my goals? You spend two hours of mental energy on a decision you have already made a dozen times. A decision agent replaces that agonizing with pre-set criteria — minimum rate, maximum weekly hours committed, alignment score against three stated priorities. When the inquiry arrives, you run it through the checklist. The answer emerges in minutes, not hours. The decision was made weeks ago. The situation just activated it.
This concept is part of Phase 21 (Agent Fundamentals) in the How to Think curriculum, which builds the epistemic infrastructure for agent fundamentals.

After completing this path you will use AI as a thinking partner without judgment atrophy: your mental models and assumptions externalized where AI can challenge them, recurring decisions routed through explicit frameworks, decisions captured with their reasoning so both you and the AI learn from outcomes, and a clear line around the judgments that stay yours.
