Knowledge, uncertainty, decision, COVID-19, SARS-CoV-2


The knowledge in the context of COVID-19 pandemic must be viewed from the perspective of its purpose: the intention to limit the effects and spread of SARS-CoV-2, respectively to cancel them. In order to increase the level of knowledge we identify some of the possible classifications, based on them allowing a first outline of uncertainty. The purpose of the analysis is to contribute to the clearest possible identification of the known and the unknown, thus creating a more stable cognitive field for effective public health decisions. Given that measures to combat the COVID-19 pandemic along with its effects is one of humanity's priorities, it is useful to clear up some of the issues that are likely to have improper meanings. The identification of each situation that includes significant doses of unknown and the public recognition of the uncertainty represents the condition for the possibility of robust public policies. Indicating the place that each current aspect occupies in one of the four cognitive quadrants is an important cognitive work. The position we adopt is characteristic for cognitive skepticism, trying to indicate some of the knowledge`s limits of and the risks of pseudo-knowledge. The article is a theoretical approach, based on some epistemological principles of critical thinking, the starting point being the belief that knowing what you do not know (to shape the uncertainty as appropriate as possible) is an essential part of the knowledge.
