Concern 76 · Working draft · editorial review in progress
Distinguisher exhaustion
AI-content detection limits are the difficulty of reliably deciding whether material was produced by a person or an AI, especially as writing methods change.
Understanding the concern
The register calls this distinguisher exhaustion, but that is not a standard guarantee that detection will always fail. Detectors look for patterns, and both human writing and generated writing can fall outside what a detector expects.
Studies have found false accusations and ways that detector performance changes with text style. A detector score should not be treated as proof of authorship. The consequences of a wrong accusation matter as much as catching machine-written work.
An example
A student writing simply in a second language may resemble the patterns a detector incorrectly associates with AI.
Illustrative unless identified as a documented case.
Words in plain English
- AI
- Software that learns patterns from examples or uses rules to perform tasks such as recognizing images or generating text. It can make mistakes and does not understand every situation as a person would.
Evidence and its limits
Studies document detector limitations under tested conditions; they do not establish that all detection is impossible.

Virtues and principles to consider
Virtues are qualities we practice in how we treat people and make choices. They are not scores for judging someone. Use these ideas to explore what a thoughtful response could look like.
Truthfulness
Truthfulness means making claims that match the evidence and being clear about what we do not know. It includes correcting mistakes rather than protecting a polished story.
Check sources, label guesses, and distinguish a trial result from a proven benefit. If AI helped produce a claim, someone still needs to take responsibility for checking it.
Ask together: What can we honestly say, and what still needs checking?
Justice
Justice means fair treatment, fair procedures, and attention to who receives benefits and burdens. It asks whether people with less power can be heard and seek repair.
Look at outcomes across different groups and individual cases. Provide a usable way to challenge decisions and correct harm. Equal wording in a policy does not guarantee equal treatment in practice.
Ask together: Who benefits, who bears the cost, and who can challenge the decision?
Stewardship
Stewardship means caring for resources and systems that others depend on, including people who will use them later. It looks beyond the benefit of a quick launch.
Plan for maintenance, energy use, data protection, and eventual shutdown. Ask who will look after the tool when the original team moves on and how future users can avoid inheriting hidden costs.
Ask together: What are we responsible for caring for over time?
