Which of the following is NOT a method to reduce social desirability bias?

Making questions more straightforward does not directly address social desirability bias, which occurs when respondents provide answers they believe are more socially acceptable or favorable rather than their true opinions. While clarity in questions may improve understanding and the quality of responses, it does not inherently reduce the tendency of respondents to shape their answers in a way they think is more acceptable or desirable to others.

In contrast, assuring confidentiality to participants, using anonymous surveys, and encouraging honest feedback are all strategies specifically designed to mitigate social desirability bias. These methods help create an environment where respondents feel safer providing truthful answers without the fear of judgment or repercussions, thus leading to more accurate data collection.
