INTRODUCTION

English translation pending.

CORE DEFINITION

The historical system, the Qin military merit nobility, granted one rank of nobility for each severed head of an armored enemy soldier, asking neither about origin nor anything but battle merit. As a design tool its core claim is that a complex war aim can be compressed into one single, quantified, highly stimulating metric, which turned the entire state into a war machine; in a cold-start business the equivalent is choosing one crude core metric, like new-user count, over-rewarding it, and going all in. The condition, since this is a historical institution rather than a modern method, is that its distortions be watched as closely as its drive.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Pick one crude core metric: compress the complex goal into a single countable number everyone can see. - Over-reward it: attach reward beyond the norm so effort concentrates. - Watch the distortion: monitor what the metric makes people stop doing, since gaming follows sharp incentives.

Anchor fast decisions

The system made each enemy head the measurable voucher for military merit and reward, aligning individual behavior with the organizational goal through an unambiguous incentive; the same compression that concentrates effort also distorts it, since a single countable target invites gaming and collateral damage.
