Obligatory Passage Point, OPP
Updated 2026-08-09
INTRODUCTION
English translation pending.
CORE DEFINITION
A concept from actor-network theory, associated with Michel Callon's study of scallop research, describing a point that must be traversed by all actors if their interests are to be served. Whoever defines and controls that point can translate others' goals into dependence on themselves. The core claim is that power in a network comes from position rather than from formal authority. The qualification is that control is contingent on the node remaining genuinely unavoidable and on the absence of alternatives.
SCAFFOLDING EFFECT
Reduce cognitive load
- Use Node Identification: Find the points in the network that every participant must cross. - Use Position Design: Build or occupy a node whose use is required for others to achieve their goals. - Use Redundancy Check: Verify whether alternative routes exist before assuming a node is unavoidable.
Anchor fast decisions
When all paths to a goal pass through one node, its controller can set terms for access without needing authority over the actors themselves. Others comply because their own objectives depend on passage, not because they are subordinate. The leverage therefore depends entirely on the absence of alternatives, which is why building a second route dissolves the power of the first.
