The effects of epistemic feedback can be viewed as either negative or positive depending on the goal of the observations.
When trying to get a secret survey of results, epistemic feedback can be seen as a negative factor which distorts the original data.
The risk comes when the feedback temporarily slants the evaluation of quality so that long-term performance is hindered by distortion in the way results were measured.
Some methods to compensate for epistemic feedback are to use a "double-blind study" or to conduct secret surveys to quietly check the results.
Also, "controlled experiments" can be used, where the outcome is adjusted for the placebo effect of reactions to unchanged parameters.
