Concern 4 · Working draft · editorial review in progress
Sampling frequency bias
Sampling frequency bias occurs when some kinds of examples appear much more often than their relevance to the intended task warrants.
Understanding the concern
Repeated exposure can make an AI treat the most common material as the normal case. A very active group of online writers may supply far more text than a much larger group that posts rarely.
Unlike coverage bias, the quieter group may be present. The concern is how much influence each group receives. Counting documents alone is not enough; teams may also need to examine repeated authors, copied material, and the intended population.
An example
A town survey that counts every comment lets one person posting 100 times outweigh 50 people posting once.
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
These sources support auditing dataset composition and sources; the voting-style example is illustrative rather than a study result.

A question to discuss
Are we measuring how many people hold a view or how often a few people repeat it?

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?
