Social desirability bias

The tendency of respondents to answer in ways that present themselves favorably rather than accurately.

Social desirability bias is the tendency for respondents on self-report assessments to answer in ways that present themselves favorably — endorsing items that make them look good, healthy, or competent, and rejecting items that don't, regardless of what they actually think or do.

The effect is strongest when respondents perceive stakes (job applications, court-ordered evaluations, treatment intake) and weakest for anonymous, low-stakes administration. Well-designed assessments mitigate it through neutral wording, mixed item polarity, validity scales, or forced-choice formats. For any self-report, it's a factor worth considering when interpreting individual scores.

Self-report — An assessment format in which respondents rate their own thoughts, feelings, or behaviors.
Response style — Systematic ways respondents answer items that aren't driven by item content — patterns like agreeing-with-everything or always picking the middle.
Forced-choice item — An item format that asks respondents to choose between options designed to be equally desirable, reducing social desirability effects.
Reverse-scored item — An item worded so that endorsement indicates the opposite of the construct being measured; its score is flipped during calculation.
