Concern 6 · Working draft · editorial review in progress
Temporal bias
Temporal bias occurs when the period represented in training data does not fit the time in which the AI is used.
Understanding the concern
Habits, prices, language, and institutions change. A system can faithfully reproduce patterns from its training period while giving poor guidance about the present. A clear date on a source matters as much as its apparent authority.
This concern focuses on the age and time window of the evidence. Drift describes changes after deployment. The two overlap, but an AI can already have a time mismatch on its first day of use.
An example
A travel assistant relying on an old timetable may confidently recommend a service that no longer runs.
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.
- Training
- The process of using examples to shape how an AI model behaves. Learning patterns from material does not establish that the material is true or fair.
- Drift
- A change over time in data or real-world conditions that can make a system less reliable.
Evidence and its limits
Datasheets recommend recording collection periods and maintenance; the entry applies that documentation principle to time-sensitive use.

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?
