• B. Polls always reflect true beliefs.
• C. It improves accuracy of polls.
• D. It only affects online polls.

Answer: (A)

Social desirability bias in polling happens when people give answers they think are socially acceptable rather than what they truly believe. This pushes responses toward attitudes that are viewed favorably and away from beliefs that might be stigmatized, making the collected data look more like the “desirable” stance than the respondent’s real view. The effect is especially likely in polls that feel less anonymous, such as face-to-face or live-interviewer surveys, though anonymous formats can lessen it but not always eliminate it. Because polls rely on self-reported opinions, this bias can distort estimates of public opinion and mislead interpretations of how people actually feel. To reduce it, researchers use methods like ensuring anonymity, carefully neutral wording, indirect questioning, or techniques designed to protect respondent privacy. In short, it explains why people might report socially approved attitudes instead of their true beliefs, which is the core way this bias shifts poll results.
