Data becomes intelligible to a team not simply when everyone can access it, but when collaborators can identify the same features, direct one another’s attention, check interpretations, and repair misunderstandings. That is a practical way to think about “data intelligibility”: a useful framing for shared work, not a standardized technical score.
What does mutual understanding mean in data work?
A chart or dataset does not explain itself. People make it meaningful together by referring to its parts, asking what others are looking at, and testing whether a shared interpretation holds. In collaborative analysis, this shared reference—often described as common ground—lets participants build on one another’s observations rather than merely exchange information.
This shifts the question from “Was the chart delivered?” to “Can the people working with it tell what is being discussed and respond to the same thing?” Access to a file, a clear display, or accurate transmission can help, but none alone establishes that collaborators interpret its meaning alike.
Why delivery is not the same as intelligibility
Communication can be considered at several levels. A signal may reach its destination, yet its meaning may remain ambiguous; even an understood message may not produce the intended effect. Healey and colleagues’ 2018 introduction on miscommunication explains why a sender-channel-receiver model is useful for thinking about transmission noise but less able to account for different interpretive codes, underspecified meanings, or misunderstandings that participants notice and address.
#1 Best Overall
In conversation, people often manage uncertainty through interaction: they ask for clarification, restate a reference, or otherwise check whether they are following one another. Conversation analysis examines these procedures as observable ways participants handle understanding, rather than defining mutual understanding solely as identical private mental states. These are different analytical approaches, not a settled replacement of one definition by another.
How collaborators establish common ground
Make reference visible, audible, or tangible
Shared understanding is easier to build when a person can indicate the feature under discussion and others can locate it through their own access method. The relevant representation may be visual, tactile, spoken, or multimodal. What matters is not that everyone experiences the data identically, but that the team can coordinate around a reference and check it.

Check interpretations while work is underway
Questions such as “Which point are you referring to?” or “Do you mean the next sentence?” can expose a mismatch before it shapes later analysis. Treat such checks as part of the work, not as evidence that communication has failed. A useful workflow makes it ordinary to clarify a reference and confirm what a collaborator has understood.
Use repair to recover from divergence
When collaborators discover they were referring to different features or interpreting a term differently, they need a way to correct course: identify the discrepancy, restate or relocate the reference, and check that the correction has landed. The specific repair will depend on the task and the participants’ access needs; there is no single procedure established by the studies cited here.

A qualitative contextual inquiry by Jonathan Zong and Arvind Satyanarayan at Bower Lab, an oceanography lab led by blind principal investigator Amy Bower, examined how blind and sighted collaborators coordinated around data. The authors frame multimodal representations as resources for communication and joint work, not only as a way for an individual to extract information independently.
In the examples they describe, tactile data representations helped collaborators point to data, check whether they shared a reference, and signal continued engagement. The work also involved taking turns at a shared computer with spoken cues and an explicit handoff protocol. A cursor perceptible through both screen-reader narration and the visual monitor helped clarify references such as “this next sentence.”

The lab’s dedicated Access Assistant role was part of the institutional arrangement supporting tactile materials and the workflow. These are grounded examples from one oceanography lab, not evidence that every mixed-ability team will need or can reproduce the same setup. They do show why accessibility decisions can affect how a group directs attention, takes turns, and confirms shared reference.
What documentation can—and cannot—do for data reuse
Collaborators are not always working together in real time. Future users may encounter a dataset without access to its creators, making written catalogues and metadata an important guide to interpretation. A 2021 study of a digital scientific dataset discusses how catalogue design can instruct reusers through redundancies and cross-checks: information that helps users detect inconsistencies or test an interpretation against another clue.

Documentation can anticipate ambiguity and make self-correction more feasible, but it cannot ensure that the original creators and later users reach mutual understanding. Where possible, record the meaning of fields, units, conventions, and transformations in context, and include cross-checks that help a reader notice when an interpretation does not fit. Treat those measures as aids to interpretation, not a guarantee that interaction will never be needed.

The following questions synthesize themes from the cited work; they are not a validated scoring framework.
- Access across modalities: Can collaborators engage with the relevant data through the sensory modes and tools available to them?
- Shared reference: Can one person direct attention to a feature in a way others can locate?
- Checks and participation cues: Can collaborators confirm they are tracking the same reference and indicate when they remain engaged?
- Mismatch recovery: Is there a workable way to identify and repair differences in interpretation?
- Reuse without the creators: Do documentation and cross-checks help later users test their understanding when direct clarification is unavailable?
These questions help teams discuss concrete conditions for shared interpretation. They do not establish whether a dataset is universally intelligible, because meaning depends on the people, task, access arrangements, and context in which it is used.
