# Asymmetry of Abstraction **Domain:** Governance / Modeling / Power **Doc Type:** Canonical Bridge Concept **Maturity:** Developed **Concept Status:** Interpretive synthesis developed in this corpus ## Definition **Asymmetry of abstraction** is the power differential between actors living local reality and higher-order systems operating on compressed representations of many such realities. The local actor often possesses richer context but narrower reach. The abstracting system possesses less detail about any one case but greater capacity to compare, allocate and revise conditions across the population. ## Governing Variable The asymmetry governs scale of consequential action: who can convert a model into changes affecting many lower-level participants. ## Material and Computational Manifestation A resident sees a street, a clinician sees a patient and an operator sees a machine. A city model sees flows, a health model sees risk distributions and a fleet controller sees resource state. Both levels can be valid, but only one may be able to change the surrounding conditions at scale. ## Relation to Governance The concept explains why formal local autonomy can coexist with [[wiki/Model-Space Sovereignty|model-space sovereignty]] above it. [[wiki/Freedom Below the Control Plane|Freedom Below the Control Plane]] names the resulting distinction between freedom to act and authority to revise the architecture. ## Constitutional Question and Failure Modes Compressed models can erase context and make appeal expensive because the subject must translate lived reality into the system's vocabulary. Legitimate abstraction requires uncertainty, local evidence, contestability and a route by which lower levels can revise the higher model. ## Related Ontology [[wiki/State Legibility|State Legibility]] · [[wiki/Aggregated Digital Twin|Aggregated Digital Twin]] · [[wiki/Model-Space Sovereignty|Model-Space Sovereignty]] · [[wiki/Representational Due Process|Representational Due Process]] · [[wiki/Multiscale Stewardship|Multiscale Stewardship]] ## Skeuomorphic Interval Context [[articles/The Skeuomorphic Interval|The Skeuomorphic Interval]] connects asymmetry of abstraction to [[wiki/Provisioned Environment|provisioning]]. A person encounters a price, route, job, or social opportunity as immediate reality while a higher layer encounters distributions and intervention opportunities, then returns changed conditions to the person. ## Simple Reminders, Quotations, and Thoughts > “You can’t point to a variable or an addition instruction in Babbage’s machine—only to the mechanical activities that represent them. What Lovelace can only tackle with informal explanation was made more precise in the 1960s when computer scientists such as Oxford’s Dana Scott and Christopher Strachey used separate abstractions to model both the machine and the program running on it, so that precise mathematical reasoning could predict its behavior. These concepts have become further refined as computer scientists like Samson Abramsky seek out more subtle abstractions using advanced logic and mathematics to capture not only classical computers, but quantum computation as well.” > **— Ursula Martin**, *2017, Edge Annual Question, “WHAT SCIENTIFIC TERM OR CONCEPT OUGHT TO BE MORE WIDELY KNOWN?”* [[reminders/Information/Abstraction Lets Us Predict the Behavior of Machines by Ursula Martin|Abstraction Lets Us Predict the Behavior of Machines by Ursula Martin]]
