Authenticity Calibration

Authenticity calibration is a proposed label on this site for how closely confidence in a media-authenticity judgment matches actual accuracy. It asks whether people know when their judgments are reliable. Someone can make several correct decisions yet be poorly calibrated if they are just as confident when wrong. Calibration and detection accuracy measure different things.

Evidence for the claims on this page: Not established for this proposal

The cited studies concern authenticity judgments and media responses. This proposed calibration measure would need explicit confidence and accuracy tests.

What it is

Authenticity calibration is proposed as the degree to which subjective confidence in judgments of media authenticity corresponds to objective judgment accuracy under specified conditions.

This is a working formulation used by this site. The research below provides context rather than a source for this exact definition.

In everyday language

It asks whether you are as good at identifying authentic media as you think you are.

What it isn't

It is not simply detection accuracy; calibration compares accuracy with confidence.

An example

Across many judgments made with 90% confidence, a viewer is correct about 60% of the time. That pattern suggests overconfidence in that task.

Key features

  • Confidence
  • Accuracy
  • Requires defined test conditions
  • Can be over- or under-calibrated

How it relates to synthetic imprinting

Comparing confidence with accuracy could help assess judgments after synthetic-media exposure. Confidence and detection accuracy are separate measurements.

Research context

Calibration is established in judgment research, but this exact media-authenticity formulation is proposed here. (Nightingale and Farid, 2022; Vaccari and Chadwick, 2020)

Established Concept

Media Literacy

Media literacy is the ability to access, analyze, evaluate, create, and act using media, including understanding its sources and purpose.

Emerging Concept

Provenance Signal

A provenance signal provides information about where media came from or how it was changed. Knowing its origin does not establish that its claims are true.

Emerging Concept

Deepfake

A deepfake is realistic synthetic or manipulated audio, imagery, or video that depicts a person or event differently from what actually occurred.

Established Concept

Trust Calibration

Trust calibration is the alignment between someone's trust in a system and what that system can reliably do in a particular context.

Established Concept

Content Credentials

Content Credentials are digitally signed provenance records that can document how media was created or edited using the C2PA standard.

Sources and what they support

These sources concern related concepts. They do not establish or endorse this proposed terminology.
