# Salience Engineering **Domain:** Cognition / Communication / Governance **Doc Type:** Bridge Concept **Maturity:** Developed ## Definition **Salience engineering** is the deliberate shaping of what becomes perceptually or cognitively prominent within an environment. ## Governing Variable It governs attention: which signal is noticed, with what urgency, against which background and near which decision threshold. ## Material and Computational Manifestation Signs, alarms, architecture, media ranking, interface emphasis and notification systems alter salience without determining a complete response. Bee pheromones supply a biological case in which signal concentration and context change collective behavior. ## Relation to Governance Salience engineering is adjacent to [[wiki/Affordance Engineering|Affordance Engineering]]: one shapes what is noticed, the other shapes what can be done. Together they can guide local agency without explicit command. ## Failure Modes Overstimulation, alarm fatigue, manipulation and feedback loops that reward already prominent signals can degrade judgment. Salience is not truth, importance or legitimacy. ## Related Ontology [[wiki/Behavioral Signal|Behavioral Signal]] · [[wiki/Choice Architecture|Choice Architecture]] · [[wiki/Affordance Engineering|Affordance Engineering]] · [[wiki/Attention Economy|Attention Economy]]
