When conducting systematic observation with two or more raters, reliability is indicated by high agreement among the raters. This means that the raters consistently agree on how to code the behavior being observed, which increases the validity of the observations. Less reactivity among participants or agreement among the participants are not necessarily indications of reliability, as they do not directly assess the consistency of the raters' observations. Similarly, less reactivity among the raters is not a direct measure of reliability, as it pertains to how the raters behave during the observation rather than the consistency of their coding.
