In spring 2020, in response to the COVID-19 crisis, many world leaders imposed universal lockdowns. We argue that these restrictions have not been accompanied by the epistemic practices morally required for their adoption or continuation. While in theory lockdowns can be justified, governments did not meet and have not yet met their justificatory burdens. We will not argue that less stringent policies were optimal or better justified. Rather, we explain how government leaders failed and have continued to fail to meet their epistemic duties by relying upon data, models, and evidence of insufficiently good quality to justify their actions.
