Concealment involves hiding the observation from the participants to reduce reactivity. Deception is often used to achieve this by making participants think they are not being observed, while in reality they are. To properly execute concealment, some level of deception is necessary on the researcher's part. However, it is important to note that any deception used in research must be necessary and ethical, and participants must be debriefed afterwards to ensure they fully understand the nature of the study.
