Which statement about IQ tests and bias is supported by the material?

• A. If biased, they would underpredict later success for certain groups, and this does not happen
• B. IQ tests are biased across all groups
• C. No one studies IQ test bias
• D. IQ tests cannot be analyzed for quality

Answer: (A)

Bias in IQ tests is evaluated by looking at how well the test predicts future success for different groups. If a test were biased against a group, you’d expect that group’s actual later success to be lower than what the test predicted. The material notes that this underprediction does not occur, so the idea that biased tests would systematically underpredict for some groups isn’t supported. Instead, the observed predictive relationship doesn’t show that kind bias, which is why this statement is the best choice.

The other views go beyond what the material supports: it doesn’t claim that IQ tests are biased across all groups, it doesn’t say no one studies IQ test bias, and it doesn’t assert that IQ tests cannot be analyzed for quality.
