Tuesday: How Bias Gets In

Ben hears about a reading app that listens to students read aloud and scores them.

He thinks of his class. Some students have the local accent. Some grew up in other regions, and some speak two languages at home.

Would the app hear all of them equally well? Ben realizes he does not know, and that the answer matters.

What NIST says about bias

NIST's Generative AI Profile lists harmful bias as one of the risks of generative AI.

It says these tools can amplify historical, social and systemic biases. Amplify means make louder or bigger.

It also names performance gaps. A tool can work worse for some groups or some languages.

NIST says this may come from training data that does not represent everyone the tool is used for.

Where bias can enter

This table is a way to think about it, not a list of proven causes for any one tool.

StageWhat can go wrongA question to ask
Collecting dataSome people or languages are rare or missing.Who is missing from the data?
Learning patternsOld, unfair patterns in the data get copied.What past habits might it repeat?
Making outputsThe tool works worse for some groups.Who does it get wrong more often?
Using outputsPeople trust the result without checking.Who checks before anyone acts on it?

The last row links to week 4. NIST describes automation bias as trusting a machine too much, and says it can make other risks worse.

A biased output that nobody checks can do more harm than one a person questions.

TRACE HOW BIAS CAN REACH A PERSON
  • ?The tool learns patterns mostly from the groups it saw.
  • ?Some groups are rare or missing in the data.
  • ?Someone acts on the output without checking.
  • ?The tool works worse for the missing groups.
  • ?People collect training data.
WHY THIS EXERCISEEach step is a place where a person could catch the problem.
NAME THE STAGE
  • Read the question.
  • Tap your answer.
A voice tool learned mostly from speakers of one region. Where did the problem start?
A manager acts on a tool's ranking without reading it. Which stage is that?
What does "amplify" mean in NIST's warning?
When a tool works worse for some groups or languages, that is a performance ____.
Data that includes the full range of people is called ____ data.
Trusting a machine too much is called automation ____.
StatementTrue or false?
NIST says generative AI can amplify historical and social biases.?
NIST says tools can work worse for some languages.?
Bias can only enter when data is collected.?
Checking an output before acting on it can stop some harm.?
WHY THIS EXERCISEKnowing every stage tells you where your own check fits.
