INTRODUCTION

English translation pending.

CORE DEFINITION

A management metaphor for two related drift patterns: crab-bucket behaviour, in which members of a group pull down anyone who climbs, and organizational sclerosis, in which growth thickens the shell of process until the body can barely move. The image is the crab: armoured, slow and unable to rise above the pile. The qualifier is that the harm lies in suppressing excellence, not in maintaining order; rules that keep a system predictable are not this phenomenon.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Signal detection: spot the moment a standout performer is quietly pulled back to the average. - Incentive audit: check whether rewards pay for conformity more than for results. - Structure check: ask whether process has thickened faster than output.

Anchor fast decisions

When a group rewards sameness, the cheapest strategy for each member is to cut down anyone who stands out, because visible excellence makes everyone else look worse. Over time the strongest performers either conform or leave, so the average holds and the group's ceiling drops. In organizations the same dynamic shows up as layers of approval that grow with headcount and slow every decision.
