What is the role of response bias controls?

• A. To calibrate difficulty levels
• B. To detect response bias and social desirability
• C. To adjust for time of day
• D. To store results in secure database

Answer: (B)

Response bias controls are designed to detect bias in how people answer—specifically social desirability and related tendencies. In surveys and assessments, respondents may try to present themselves in a favorable light or choose answers they think are acceptable, which can skew results. Validity or lie scales are often used to spot these patterns, enabling researchers to flag or adjust for biased responses. This helps ensure the data reflect true attitudes rather than impression management or other biased responding.

Calibrating difficulty levels relates to item difficulty rather than bias in responses, while adjusting for time of day concerns performance fluctuations rather than response tendencies. Storing results in a secure database is about data management and security, not detecting how people answer.
