Information Theory

← Back to Prime Abstractions by Origin Domain

21 primes originate from Information Theory and 52 more draw from it as a secondary origin — sort the Origin column to separate them. They span 19 subdomains; sort by that column to group them, or click any subdomain to filter to it.

Prime	Origin	Subdomain	Description
Adverse Selection	Also draws from	—	Hidden pre-contractual types make participation under uniform terms systematically more attractive to the types worst for the uninformed side, degrading or unraveling the pool.
Agency Problem	Also draws from	—	Misaligned incentives.
Approach-Avoidance Conflict	Also draws from	—	A single goal that pulls and repels at once, where competing gradients balance at an intermediate point and trap the actor in vacillation.
Associative Memory	Also draws from	—	Content-addressable storage where a cue retrieves linked content.
Backpressure	Primary	Distributed Systems	A return signal from a downstream stage throttles upstream production to its own capacity, converting a one-way push into a two-way conversation that holds the system at the bottleneck's throughput instead of accumulating hidden queue debt.
Belief Formation	Also draws from	—	Commitment-transition by which an agent comes to hold a proposition as true and act accordingly.
Branching and Merging	Primary	Information Computation	Lines of development that diverge and later recombine into one.
Channel	Primary	Transmission Medium	A bounded conduit between source and receiver whose capacity, alphabet, and noise profile are constitutive of what can cross it — a fact outside the channel's bandwidth, codebook, or noise floor is structurally inexpressible through it.
Channel Capacity	Primary	Throughput Bounds	Any information-bearing medium has a hard upper bound on reliable throughput that effort cannot exceed.
Color Harmony	Also draws from	—	Pleasing color relationships.
Commensurability	Also draws from	Decision Analysis	Diverse values expressed in common metric enabling comparison.
Commitment Device	Also draws from	—	A self-imposed constraint that binds one's own future choices.
Compression	Primary	—	Reduce redundancy.
Conditional Entropy	Primary	Shannon Information Theory	Measure the expected uncertainty that remains about a target after a specified context is known.
Coordination Problem and Equilibrium Selection	Primary	Game Theory	Multiple stable equilibria require alignment on single outcome.
Data Integrity	Also draws from	—	Accuracy and consistency preserved.
Deadlock	Also draws from	—	Mutual blocking processes.
Diminishing Incremental Gains	Also draws from	—	Reduced benefit per unit.
Economies Of Scope	Also draws from	—	Cost savings from producing varied outputs together.
Emphasis	Also draws from	—	Highlighting priority element.
Emphasis (Focal Point)	Also draws from	—	Highlight key element.
Encoding And Decoding	Primary	Communication	The paired transformation by which content is converted into a transmissible code by an encoder and recovered from it by a decoder, with faithful round-trip conditional on a shared scheme.
Entanglement	Also draws from	—	Linked distant states.
Entropy (Thermodynamic Sense)	Also draws from	—	Log-count of microstates consistent with a macrostate; non-decreasing in an isolated system.
Environmental Coupling Strength	Also draws from	—	Rate of energy, information, or material exchange across boundary.
Epistemic Justice	Also draws from	—	Fair knowledge production.
Escape and Leakage	Also draws from	Fluid Systems	Constrained quantities exit through unintended pathways.
Expected Utility	Also draws from	—	Ranking risky options by their probability-weighted utility.
Formalization	Also draws from	Logic	Rendering informal practice into explicit, codified, rule-governed form.
Garbage In, Garbage Out	Primary	Data Quality and Pipeline Integrity	The quality of a transformation's output is bounded above by the quality of its inputs; no downstream sophistication can repair defects already present in the input.
Groupthink	Also draws from	—	Conformity overrides realism.
Habitus	Also draws from	—	Internalized dispositions.
Herding Behavior	Also draws from	—	Mimicking others.
Holarchy	Primary	Systems Theory	Nested ordering in which each unit is at once an autonomous whole and a dependent part.
Information	Primary	—	A difference, constraint, or patterned selection that can change an interpreter's uncertainty, representation, or action when carried through a usable relation between possible states.
Internalization	Also draws from	—	Adopting external norms as one's own internal standards.
Linearization-Meaning Mismatch	Primary	Representation and Serialization	Multi-dimensional content forced through a serial channel is ordered by a principle that does not match the one the consumer reasons by.
Liquidity	Also draws from	—	Ease of conversion.
Marginal Utility	Also draws from	—	Additional satisfaction.
Markov Process	Primary	Probability Theory	Future state depends only on the present, not the full history.
Metasystem Transition	Also draws from	—	Systems form higher-level system.
Moral Hazard	Also draws from	—	Risk-taking under protection.
Negative Space	Also draws from	—	Empty space shaping form.
Non-Zero-Sum Game	Also draws from	Game Theory	A strategic interaction whose joint payoff is not fixed: cooperative play can create value and destructive play can destroy it, so the size of the pie is endogenous to the strategy profile.
Normativity	Also draws from	—	What ought to be.
Observer Effect	Also draws from	—	Observation alters system.
Opportunity Asymmetry	Also draws from	—	Agents possess unequal access to actions and favorable outcomes.
Optionality	Also draws from	—	The asymmetric value of having a choice—bounded downside, unbounded upside—without obligation to act.
Paradigmatic vs. Syntagmatic Relations	Also draws from	—	Any structured system can be decomposed along two orthogonal axes, the vertical set of substitutable alternatives that could fill a slot and the horizontal chain in which selected items are combined.
Phase Space	Also draws from	—	All possible system states.
Price Mechanism	Also draws from	—	Supply-demand pricing.
Public Goods	Also draws from	—	Non-excludable goods.
Public vs. Private Contexts	Also draws from	—	Audience presence alters motivation and behavior through reputation.
Receptor Saturation	Also draws from	—	Plateau effects at capacity.
Redundancy	Also draws from	—	Duplicate critical components.
Regret	Primary	Decision Theory	Disvalue from comparing an outcome against a better forgone alternative.
Resonance	Also draws from	—	Amplified response at frequency.
Reversibility and Irreversibility	Primary	Decision Theory	Actions or transitions may or may not be undone or reverted.
Risk	Primary	Decision Theory	Exposure to a known distribution of possible outcomes.
Risk Aversion	Also draws from	—	Preference for certainty.
Risk–Return Tradeoff	Also draws from	—	Risk vs reward.
Rock-Paper-Scissors (Intransitive Cyclic Dominance)	Primary	Game Theory	A beats-relation that closes into a cycle rather than a ranking, so no option dominates and the system is governed by rotation and coexistence.
Second Law of Thermodynamics	Also draws from	—	Entropy increases.
Social Dilemma	Primary	Game Theory	Individually rational defection yields a collectively worse outcome (canonical form: the Prisoner's Dilemma).
State and State Transition	Also draws from	—	Captures system condition and evolution.
Subadditivity	Also draws from	Analysis and Inequalities	A combined whole never evaluates above the sum of its separately evaluated parts, so decomposition supplies a guaranteed upper bound.
Systems Thinking	Primary	Systems Theory	Analyzing a whole through the relationships and feedback among its parts.
Temporal Decay and Degradation	Also draws from	Materials Science	System properties or capabilities systematically diminish over time.
Texture	Also draws from	—	The fine-grained surface variation beneath an object's gross form that carries perceptual, material, and emotional information rather than mere decoration.
Tragedy of the Commons	Also draws from	—	Resource depletion from self-interest.
Ultra-Stability (Ashby's Concept)	Also draws from	—	Multi-level feedback preserves viability.
Validity-ending Event	Primary	Provenance and Lifecycle	A discrete, dateable moment at which a previously in-force entity is declared no longer valid while continuing to exist as a retained historical object.
Winner's Curse	Primary	Auction Theory	Winning a common-value contest is itself evidence of overpayment.
