Principlev1
Use simple decision rules that ignore most available
Use simple decision rules that ignore most available information in high-uncertainty domains where signal-to-noise ratio is low.
Why This Is a Principle
This PRINCIPLE follows from Simple decision rules using less information can outperform (simple rules can outperform complex models) and Human beings make decisions under conditions of incomplete (bounded rationality), with support from Signal-to-noise ratio determines the capacity of a (signal-to-noise ratio). It prescribes WHEN and HOW to simplify (in high-uncertainty domains) rather than stating that simple rules can work. The fast-and-frugal heuristics research grounds this.
