Acquiescence Bias

Acquiescence bias is the tendency to agree with the interviewer. In general, participants are more likely to agree than to disagree. Thus, the question should not imply that there is a “correct” answer. Instead of asking for agreement or disagreement with a predefined statement, researchers can ask users to explain their point of view.

Example

“Would you agree that you are satisfied with the current interface?” This question nudges the user to agree and could lead to acquiescence bias.

“How do you feel about the current interface?” This phrasing is open-ended and does not lead participants toward a particular sentiment.
