According to this research study, communicating scientific uncertainty about public health threats must be done cautiously.

The management of public health crises from viral pandemics and other novel threats presents a dilemma: open communication of scientific uncertainty is ethically desirable, but practically problematic in potentially perpetuating ambiguity-averse perceptions and behaviors that can undermine public health. In this study, uncertainty-normalizing communication strategies did not avert ambiguity in messages as expected and thus, there is still a need to determine the best way to convey scientific uncertainty to ensure thoughtful, deliberative decision making that avoids extremes of overconfidence and underconfidence.
