Definition of Acquiescence Bias



Acquiescence bias or agreement bias is a bias in the respondents’ feedback on the survey by confirming the statement asked without knowing their position or the statement. Acquiescence bias arises when a participant is asked to confirm the statement with only “agree/disagree” or “yes/no” options. Most participants tend to go with the yes statement due to acquiescence bias.

 


Respondent is more skewed to yes answer because they want other people to like them with their agreeable responses.

 


Example of Acquiescence Bias:

During cross-examination, the lawyer asks the witness “Did the person you saw wear glasses?” the witness is more likely to answer yes even though he didn’t saw the person.

To reduce acquiescence bias, researchers recommend using multiple options or open-ended questionnaires for data collection so that the accuracy of the data is achieved.
