This can have serious implications in areas like medical research where, for example, a new form of treatment may be evaluated. This can remove some of the research expectations that come from knowing the study purpose, so observers are less likely to be biased in a particular way. Information bias occurs during the data collection step and is common in research studies that involve self-reporting and retrospective data collection. Interviews generally have less observer or participant bias. You treat Group B as if you expect the participants to still be in pain and frame your questions more negatively than for Group A.
