INTRODUCTION

English translation pending.

CORE DEFINITION

The dog in the manger is Aesop's fable of a dog that lies in the horse's feed trough, eating no hay itself but barking to keep the horse away. Applied to people, it names the person who holds a resource they cannot use, a spare server, an unused dataset, a meeting slot, out of malice or territorial instinct, blocking someone who genuinely needs it. Since the holder does not value the resource, negotiation has nothing to trade, and only higher authority can clear the block.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Blocker identification: Notice when a resource is idle yet still denied to the person who needs it. - Trade test: Ask what the holder would accept, and if nothing, conclude that value is not the currency. - Escalation route: When no trade exists, move the decision to an authority that can reallocate the asset.

Anchor fast decisions

The holder is not optimizing for value, since they derive none from the idle resource, but for territory and the pleasure of denial. That makes the interaction non-economic: there is no price at which both sides gain, because the holder's payoff is the refusal itself. Negotiation therefore fails on its own terms, and the block persists until an external authority changes the allocation or the holder's incentives.
