Which of the following is an example of bias caused by perspective differences?

• A. Recall/hindsight bias
• B. Observer bias
• C. Social desirability bias
• D. Selection bias

Answer: (B)

Bias that stems from perspective differences happens when the person observing or rating a behavior brings their own beliefs, expectations, or frame of reference into what they see, causing systematic differences in data. This is observer bias: the observer’s viewpoint shapes how they notice, interpret, and record information, so two observers might rate the same behavior differently simply because of their individual perspectives. For example, one clinician might interpret a vague agitation cue as a sign of high anxiety while another might see it as minor restlessness, leading to inconsistent assessments. This kind of bias threatens reliability and validity, and it can be reduced by using standardized rating scales, training to apply criteria consistently, employing multiple blinded raters, and incorporating more objective measures. In contrast, recall/hindsight bias involves distortion of memory by current knowledge, social desirability bias involves presenting oneself in a favorable light, and selection bias arises from non-random sampling, which are distinct mechanisms from differences in observers’ viewpoints.
