Why is it important for an observer to be aware of reactivity?

Being aware of reactivity is crucial because it recognizes that the presence of an observer can influence a person's behavior. When individuals know they are being watched, they may alter their actions or responses, consciously or unconsciously, which can impact the integrity of the data being observed.

Understanding this concept helps observers to anticipate and account for potential changes in behavior, leading to more accurate interpretations of the data. This consideration is particularly important in settings where the goal is to assess natural behaviors rather than those induced by the observation itself. By acknowledging reactivity, observers can employ strategies to minimize its effects, ensuring a more authentic and accurate representation of the subjects’ normal behaviors.
