Principle of Least Effort
Updated 2026-08-02
INTRODUCTION
English translation pending.
CORE DEFINITION
Formulated by linguist George Kingsley Zipf, the principle of least effort states that organisms, including humans, act so as to minimize the probable average rate of work expended toward a goal. Zipf used it to explain why frequent words are short and why language drifts toward economy of articulation. The principle predicts behavior across domains, from information seeking to tool use. Key qualification: least effort is a default tendency rather than an absolute law, since people expend extra effort when accuracy, safety, or status demands it.
SCAFFOLDING EFFECT
Reduce cognitive load
- Predict flows: assume users and colleagues take the lowest-friction route available. - Design the default: make the correct path the easiest path rather than arguing for discipline. - Diagnose workarounds: treat every shortcut as evidence that the intended path costs too much.
Anchor fast decisions
Effort consumes time and energy that could serve other goals, so reducing it frees resources for competing demands. Because the cost of a path is often visible while its benefit is uncertain, the cheaper route wins by default. This makes friction, rather than preference, a main determinant of behavior, which is why changing costs reliably changes what people do.
