Concern 21 · Working draft · editorial review in progress
Bias in labels vs bias in inputs
Bias in labels occurs when the answers attached to training examples carry unfair judgments, even if the examples themselves are balanced.
Understanding the concern
Labels may say whether a message is rude, a candidate is suitable, or an image belongs in a category. These are sometimes human judgments rather than objective facts. A model can learn the judgment as though it were unquestionable.
Input bias concerns which examples enter the dataset; label bias concerns what those examples are said to mean. Fixing the first does not automatically fix the second. Review should examine instructions, disagreement, and whose judgment becomes the official answer.
An example
A dataset can include many dialects while still labeling one dialect's ordinary expressions as rude.
Illustrative unless identified as a documented case.
Words in plain English
- Model
- The learned part of an AI system. It uses patterns found during training to produce an answer or prediction.
- 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.
Evidence and its limits
Supports separating representation and measurement choices; C4 provides a concrete example of filtering decisions affecting minority-associated text.

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?
