Epistemic trust

Epistemic trust is a person's readiness to take over knowledge conveyed in language. It is an attitude rather than a conclusion. Without it, no transmission occurs, however good the testimony is.

Epistemic vigilance is targeted watchfulness against possibly faulty or deceptive information. It runs while listening, mostly below awareness. It is the filter that decides what gets through.

Epistemic mistrust is the lasting doubting of the credibility and intentions of others. It is a stable disposition rather than a single judgment. It closes the channel that trust opens.

Mentalizing is the ability to read one's own and other people's actions as driven by underlying mental states. It is what lets a listener judge whether a speaker means well. It is learned early and can be damaged.

Caregivers convey the basic patterns of knowledge uptake in early development. What is learned there shapes how a person later treats strangers who claim to know something. Trust has a history before it has a subject.

Testimony is the transmission of beliefs and knowledge through the statements of other people. It is the ordinary route by which most of what anybody knows arrives. Everything else on this page concerns how that route is guarded.

Ostensive cues such as eye contact signal to the recipient that what follows is relevant and meant for them. They open the channel before any content arrives. In text and on screens they are simulated rather than present.

Credulity is the uncritical adoption of information without prior examination. It is the failure mode on one side. It is cheap in the short term and expensive over time.

Hypervigilance is a defensive posture against information, reinforced by adverse experience. It is the failure mode on the other side. Somebody who trusts nothing learns nothing.

Relevance theory analyses the conditions under which a statement is taken as relevant and worth processing. It explains why some sentences are attended to and others are skipped. It is the bridge between attention and trust.

Mentalization-based therapy uses the relationship itself to restore the capacity to read mental states. It appears here because it is the clinical evidence that epistemic trust can be broken and repaired. It is a property of persons, not only of arguments.

An epistemic peer holds comparable evidence and comparable ability in assessing it. The concept matters wherever two such people disagree. Then the ordinary indications of reliability say nothing.

It treats trust as an attitude of individual subjects in direct exchange with other people. It leaves out the unavoidability of dependence, the confidence a person has in their own judgment, the virtues and vices involved, groups and communities as bearers of trust, and the technical infrastructure that now stands between speaker and listener.

Epistemic dependence is the fact that nobody manages without the knowledge of others. That dependence makes trust a necessity.

Epistemic self-trust is the confidence a person places in their own judgment. Without the internal side there is no standard against which an external claim could be weighed.

Epistemic humility is the insight into the limits of one's own knowledge. Humility is what makes trusting reasonable rather than merely necessary.

Epistemic vulnerability is exposure to damage through misplaced trust.

Epistemic insubordination is the active refusal to accept an authority's account.

Epistemic paternalism is influencing what somebody believes, for their own good. Influence is also exercised from above, by an institution or a system.

Credibility attribution is the process by which a listener assigns reliability to a source.

An epistemic agent is a party with standing in the production and transmission of knowledge. Subjects of testimony are agents with obligations.

Epistemic risk is the calculable probability and cost of being wrong. Treating trust as a risk decision changes what counts as reasonable trust.

Epistemic arrogance is overrating one's own capacity to judge. Refusal of trust out of arrogance looks identical from outside to hypervigilance and calls for a different response.

Epistemic alienation is a lasting estrangement from the sources a person would need.

Expertise identification is the problem of recognising who actually has the competence. A layperson has to recognise competence without the expertise in question.

Epistemic passivity is uncritical uptake without any reflective step. It is far more common than active testing through vigilance.

Epistemic misconduct is misbehaviour in the handling of knowledge. It occurs in ordinary knowledge transmission, by speakers and by listeners.

Epistemic culpability is blame for trust that was misplaced. It raises the ethical question of when somebody is at fault for believing.

An epistemic bubble is a network from which relevant evidence is absent. It is a group-level effect on what an individual can encounter.

An echo chamber actively reinforces some voices and discredits others. Active amplification is a property of the environment.

Natural pedagogy is the evolutionary account of why ostensive cues work. Without it, the cues look like technique rather than like something deeply wired.

Attachment security is the early relational basis on which later trust rests. Emotional closeness and epistemic decisions are not separate, which is why trust is not fully a matter of reasons.

Epistemic sabotage is the deliberate undermining of somebody else's capacity to know.

An epistemic community is a collective that holds and maintains knowledge. Trust also attaches to collective structures.

Trust revision is the formal updating of trust when new evidence arrives. Without a revision model there is no account of how trust should change, only of whether it exists.

An epistemic pact is the tacit agreement under which testimony is exchanged. It carries implicit obligations on both sides.

Epistemic resilience is the capacity of convictions to withstand false information.

An information ecosystem is the whole technical and social arrangement through which information reaches people. The arrangement now includes ranking, retrieval and generation.

Algorithmic ranking is the automated ordering of results. The ordering decides which witness is heard at all.

A filter bubble is algorithmic narrowing of what a person encounters.

Information validation is the technical and documentary checking of claims. Systems perform validation before any person sees the result.

A collective belief state is what a group holds together. Most practical reliance sits in trust in institutions and communities.

A search system now stands between the speaker and the listener. It selects, orders and increasingly writes the statement. The ostensive cues that once signalled a trustworthy speaker are simulated by an interface, and the vigilance that evolved for faces has nothing to work on.

If readers could tell human from machine text, their accuracy would sit well above the 50 % of a coin toss. It stayed close to 50 %.

By the three things a reader can check without expertise: state the limits of what you claim, say what the claim rests on, and change the statement when the evidence changes. Confidence without those three reads as competence and is not.
