▣ Practical example: administrative support without delegating the
decision
Context: a tool that helps summarize internal training applications.
Task: extract the stated experience and the proposed objective.
The safe approach: hide names and unnecessary attributes, test varied samples, prevent
the tool from ranking people, and review cases of weak language by hand.
Why this design: it separates reading support from the admission decision.

Verification: compare the extraction against the original text and measure errors by
document type.

measures cannot be satisfied together, so the choice must be stated and justified.

● Remember: Section summary

• Key idea: Harmful bias may arise from data, measurement, context, and use, not from
the model alone.
• Practical decision: Test varied cases, measure errors and effects, and do not use
attributes the task does not need.
• Mistake to avoid: Settling for a check of offensive language or of the overall average
performance.
