First, we must ensure the quality and objectivity of scientific evidence. We must also prove the neutrality of the scientific researchers who issued these proofs/conclusions. COVID-19 has shown us that a lot of fake science is circulating even in major scientific journals. We must then carefully read the conclusions of scientific work, paying close attention to the nuances that are used when the scientists themselves tend to doubt their conclusions. This information must also be cross-referenced with other information from other organizations/researchers.
