Privacy Friction Glossary
A Working Vocabulary for Privacy Friction and Modern Disclosure
About This Glossary
This glossary defines the core terms used throughout the Privacy Action Member framework. It is designed to give shared language to the social, behavioral, environmental, and increasingly technological dynamics that shape disclosure in semi-public settings.
Why it exists: many privacy failures in everyday life are not caused by a single dramatic breach. They arise through routine interactions, normalized scripts, and environments that make disclosure feel automatic or difficult to control.
How to use it: each term below can stand alone, but the strongest value comes from reading them together as parts of one framework.
Framework emphasis: the focus here is not secrecy for its own sake. It is the ability to manage necessary disclosure with greater discretion, clarity, and control at the moment information is exchanged.
How These Concepts Work Together
The terms in this glossary describe different parts of the same interactional process. In shared environments, individuals are often asked to disclose personal information while other people are within earshot. These moments create privacy friction, the tension between necessary disclosure and the desire for discretion.
Some concepts describe the forces that push disclosure forward, such as disclosure default, disclosure momentum, and ambient disclosure pressure. Others describe the conditions under which people feel exposed, such as the ambient audience and the invisible audience. Still others describe the mechanisms that allow individuals to reestablish control, such as privacy signaling, privacy cues, and boundary resets.
Together, these concepts form the Privacy Friction framework, a way of understanding how everyday environments influence the conditions under which personal information is revealed, managed, overheard, captured, or exposed.
Modern privacy problems often appear ordinary while they are happening. A question is asked. A response is given. A task is completed. Yet within that routine exchange, sensitive information may move farther, faster, and more publicly than the person intended. The terms below help name those dynamics precisely.
Foundational Concepts
These terms establish the core logic of the framework.
Privacy Friction
Privacy friction is the hesitation, tension, or adjustment that appears when a person is asked to disclose sensitive information in a space that is not fully private. It marks the point where necessary disclosure begins to outrun discretion.

Micro-Privacy Gap
The micro-privacy gap is the brief interval between the request for sensitive information and the spoken response. Though often only a second or two long, it is the moment in which a person becomes aware of possible exposure and decides how to proceed.

Disclosure Default
Disclosure default is the interaction script that treats speaking personal information aloud as the expected baseline unless an alternative cue, format, or protocol interrupts it.

Privacy Signaling
Privacy signaling is the act of communicating a preference for discretion, reduced exposure, or greater informational control. These signals can be verbal, behavioral, spatial, or material.

Interaction-Layer Privacy
Interaction-layer privacy is the protection of sensitive information at the moment people exchange it, not only after it has been entered, stored, or transmitted within formal systems.

Ambient Audience
The ambient audience is the surrounding group of people who are not direct participants in an interaction but may overhear, infer, or otherwise be affected by what is disclosed.

Invisible Audience
The invisible audience refers to the people, devices, and systems that may receive, capture, store, or transmit personal information even when they are not acting as obvious participants in the interaction.

Privacy Mode Shift
A privacy mode shift is a change in communication behavior intended to reduce exposure, such as whispering, leaning in, shortening an answer, spelling information, or switching formats.

Discretion
Discretion is the practical ability to manage how, when, and under what conditions personal information is disclosed in a way that aligns with a person's comfort, the setting, and the sensitivity of the information involved.
Privacy Failure
A privacy failure is a moment in which a person is pushed to disclose more information than they intended, or in a way that feels exposed, avoidable, or misaligned with the environment.

Exposure
Exposure is the extent to which personal information becomes visible, audible, inferable, captured, or accessible to others during an interaction. It is not simply private or public; it often exists in degrees.

Norm Mismatch
Norm mismatch occurs when the expected behavior of a system conflicts with a person's sense of what is appropriate, comfortable, or justified in a given moment of disclosure.
Boundary Signaling
Boundary signaling refers to the communication of where personal limits should be recognized in an interaction. In privacy contexts, it helps distinguish what may be discussed openly from what should be handled more carefully.
Individual Agency
Individual agency is the person's practical ability to choose how, when, and under what conditions they disclose information. Agency is weakened when scripts, urgency, or environment make one path feel automatic.
Social Mechanics of Disclosure
These terms describe how disclosure becomes normalized, accelerated, or socially reinforced.
Disclosure Momentum
Disclosure momentum is the tendency for information sharing to accelerate once an initial disclosure has already occurred. After the first piece of personal information is spoken, additional disclosure often feels easier, more expected, or harder to resist.

Disclosure Cascade
A disclosure cascade occurs when one disclosure prompts another, creating a chain reaction of increasingly detailed or increasingly public information sharing. Cascades can occur between two people or across an entire environment.
Privacy Drift
Privacy drift is the gradual normalization of sharing more personal information, in more places, under weaker expectations of discretion. Because the shift happens incrementally, it often goes unnoticed until exposure feels routine.
Ambient Disclosure Pressure
Ambient disclosure pressure is the subtle push created by environment, workflow, proximity, tone, timing, and audience conditions that encourages people to answer quickly and publicly.
Social Boundary Signaling
Social boundary signaling refers to the cues people use to indicate that a conversational line, informational threshold, or personal limit has been reached. These cues may be direct or indirect, but they help coordinate discretion in shared environments.
Environmental and Design Conditions
These terms connect privacy outcomes to the design of spaces, systems, and routines.
Frictionless Disclosure
Frictionless disclosure is a pattern in which systems, scripts, or environments make information sharing feel seamless, fast, and normal. While efficient, it can reduce the pause in which a person might otherwise assess what they are revealing.
Context Collapse
Context collapse occurs when multiple audiences, roles, or social contexts converge in one interactional space, making it difficult to calibrate what should be shared and with whom.
Micro-Consent
Micro-consent refers to the small, often momentary forms of agreement through which people permit information exchange in practice. These moments may be weak, rushed, or poorly supported, even when they appear voluntary on the surface.
Privacy-Supportive Design
Privacy-supportive design is the intentional shaping of spaces, tools, interfaces, and workflows to make discretionary disclosure easier. Its purpose is not to obstruct legitimate information exchange, but to reduce unnecessary exposure.

PAM Framework Terms
These terms connect the theory directly to the PAM-Card and the broader intervention model.
Privacy Action Member
A Privacy Action Member is a person who actively manages and signals their privacy boundaries in shared environments. The term emphasizes participation, intention, and practical boundary-setting rather than passive concern alone.
Privacy Cue
A privacy cue is any visible, verbal, or behavioral signal that indicates a desire for greater discretion. A cue helps others recognize that a routine interaction may require a different tone, lower volume, different location, or more careful process.

Low-Friction Boundary Tool
A low-friction boundary tool is a physical or digital object that helps a person communicate privacy preferences quickly, clearly, and with minimal disruption. Its value lies in making boundary-setting easier to initiate and easier to recognize.

Boundary Reset
A boundary reset is a moment in which privacy expectations are reestablished after an interaction has begun drifting toward unnecessary exposure. It can occur through a request, a cue, a pause, a relocation, or a shift in procedure.
Taken together, these concepts describe a simple but important pattern: many everyday environments are structured to keep information moving, while very few are structured to help people pause, calibrate, and preserve discretion. The PAM framework exists at that point of intervention.
In that sense, privacy friction is not merely a problem to eliminate. It is also a diagnostic signal. It shows where an environment, a script, or a social norm is asking a person to reveal more than the setting comfortably supports. Once that point is visible, better coordination becomes possible.

Social Permission
Social permission is the perceived approval, expectation, or tacit acceptance that makes a particular level of disclosure feel appropriate. It does not require explicit consent from others; it often operates through atmosphere, routine, and example.
