AI learns from human data. Human data contains human bias.

Direct answer

AI bias is unfair or skewed output caused by biased training data, design choices or use. It matters at work when AI influences decisions about people, such as hiring or performance. Test with diverse examples, keep human oversight and follow your organisation's and local legal guidance.

Examples

  • A résumé screener that favours patterns from past hires.
  • A voice tool that works worse for some accents.
  • Image tools that reinforce stereotypes.

What to do

  1. Do not use AI alone for decisions about people.
  2. Test it with varied inputs.
  3. Check results by group where appropriate and lawful.
  4. Document how it is used.
  5. Report issues.
