Social Desirability Bias

Social desirability bias refers to the fact that in self-reports, people will often report inaccurately on sensitive topics in order to present themselves in the best possible light (1). This can be due to both self-deception and other-deception. Social desirability can affect the validity of experimental and survey research findings, but procedures such as the use of forced-choice items and proxy subjects can be effective in preventing or reducing social desirability bias (2).
