Cognitive liberty glossary.

Concise definitions for the legal, technical, and institutional terms used throughout this site.

Cognitive liberty
The principle that a person should retain meaningful freedom over thought, attention, memory, identity, mental privacy, lawful inquiry, and cognitive self-direction.
Forum internum
The internal domain of thought, conscience, and belief, distinguished from outward expression or conduct.
Mental privacy
The ability to keep thoughts, mental states, neural data, and sensitive cognitive inferences from unwanted observation, profiling, storage, sharing, or use.
Intellectual privacy
The protected space needed to read, search, draft, research, and form ideas away from unwanted observation or interference.
Search privacy
Protection for query content, query histories, associated identity, and inferences derived from information-seeking behavior.
Cognitive autonomy
The practical ability to direct one’s own thinking and decisions rather than being covertly steered by another actor or system.
Personal agency
A person’s capacity to make and act on choices, including the practical ability to refuse, change course, or choose alternatives.
Safety poison pill
A policy pattern in which a narrow, emotionally compelling harm is used to obtain a broader surveillance or control mechanism whose reach or secondary uses exceed what the harm requires.
Function creep
The expansion of a system, dataset, or authority from its original purpose into new uses.
Expansion ratchet
The institutional tendency for exceptional powers to broaden or persist because of sunk costs, incentives, weak sunsets, secrecy, and the value of retained data.
Epistemic due process
Notice, reasons, context correction, appeal, and review when an automated system materially changes access to knowledge or classifies an inquiry.
Algorithmic Discoverability Due Process
A proposed framework giving publishers notice, reason categories, evidence, appeal, timely correction, and transparency when automated systems materially suppress visibility.
Hypernudging
Dynamic, highly personalized choice architecture that uses large-scale data and machine learning to adapt influence in real time.
Persuasive technology
Technology intentionally designed to influence attitudes or behavior. Cognitive-liberty concerns increase when influence is hidden, personalized, difficult to escape, or based on intimate profiling.
Harmful capability uplift
The additional practical ability a system gives a user to execute a harmful act compared with ordinary public information and existing tools.
Over-refusal
A safety failure in which an AI system blocks or avoids a benign request because it resembles a harmful one.
Query-local intervention
A safety response limited to the immediate request and not retained as a persistent judgment about the user.
Identity separation
An architecture that prevents the party processing a query from also learning or retaining the user’s real identity when identity is unnecessary.
Oblivious HTTP
A protocol that separates the party seeing the client’s network identity from the party processing encrypted request content.
Private Information Retrieval
A cryptographic method that lets a client retrieve a database record without revealing which record was requested.
Differential privacy
A mathematical approach that adds controlled uncertainty to aggregate results so an individual contribution cannot be reliably inferred.
Anonymous credential
A token or proof that demonstrates an attribute—such as an age threshold—without revealing unnecessary identity information.
Digital identity
A credential, account, identifier, or set of verified attributes used to connect a person with digital access or activity.
Pseudonymity
Participation under a stable name or identifier that is not automatically linked to a legal identity.
Censorship drift
The gradual expansion of a narrow restriction or safety mechanism into broader control over lawful expression, inquiry, or access.
Soft censorship
Invisible omission, reframing, downranking, throttling, or answer shaping that changes what people encounter without an explicit ban or refusal.
Intermediary liability
Rules that hold hosts, platforms, providers, or distributors responsible for user activity, often creating incentives to remove more content than the law requires.
Sovereign internet
A nationally controlled network architecture designed to centralize routing, filtering, name resolution, or cross-border connectivity; resilience claims must be separated from censorship capability.
Transnational repression
Attempts by a state or aligned actor to intimidate, surveil, threaten, censor, or punish people and institutions outside its territory.
Epistemic conformity
The narrowing of questions, sources, and expressed beliefs toward what people think an observer, platform, institution, or majority will accept.
Distributed archive
A collection preserved across multiple institutions, formats, locations, languages, or legal jurisdictions so one failure or order cannot erase it.
Internet fragmentation
The division of the global internet into technically or legally incompatible networks that restrict cross-border reach, interoperability, or access.
AI memory
Persistent information used by an AI system to influence later interactions, including stored facts, preferences, summaries, inferences, or relationship context.
Provenance
Information about where a record came from, what changed it, which source is authoritative, and how a derivative relates to the original.
Neurotechnology
Technology that measures, interacts with, or influences nervous-system activity, including brain-computer interfaces and neural sensing.
Algorithmic suppression
A reduction in visibility, reach, recommendation, retrieval, or citation caused by automated ranking or classification without a formal ban on the underlying material.
Financial censorship
The use of banking, payment, advertising, insurance, fundraising, or other economic chokepoints to restrict a person or institution’s ability to publish, organize, or reach an audience.
Language censorship
Control exercised through forbidden terms, compulsory euphemisms, controlled vocabulary, semantic narrowing, or penalties attached to the words used to describe events and ideas.
Translation censorship
The omission, alteration, selective availability, or systematic mistranslation of information as it moves between languages, preventing audiences from receiving equivalent evidence.
Reader privacy
Protection for what a person reads, searches, views, borrows, annotates, or asks about, including the associated identity, timing, and inferences.
Relational privacy
Protection for the social graph revealed by communication metadata: who interacts, when, how often, and within which communities.
Censorship-resistant archive
An archive designed so no single order, failure, custodian, vendor, format, jurisdiction, or technical chokepoint can silently erase the only surviving record.
Personalized censorship
Individualized filtering, ranking, refusal, or framing based on identity, location, history, language, inferred traits, or predicted vulnerability.
Training-data censorship
Knowledge loss or bias introduced when material is excluded, mislabeled, underrepresented, or made inaccessible during the construction of AI training corpora.
Knowledge resilience
The capacity to create, discuss, fund, translate, distribute, discover, read, teach, verify, preserve, and restore information despite political, commercial, technical, or military pressure.
