the scientists are not the problem here, PUBLIC science and public institutional structures were, are, and will be. The media takes a scientist, who has a strong tendency to say "this may work, we can't be sure" and "under some conditions, we believe that it might" and turns it into "we know!"... for institutional media reasons. Some scientists like the attention and are willing to play along, to an extent. Public institutions need "certainty rhetoric" for legal and PR reasons. The reason Ivermectin was so clubbed to death wasn't because it ddn't work, it was because the legal process of emergency certification of the vaccine required that there are no working cures, so that could institutionally not be pursued. No evil intention is needed here; "we want to help and this is a legal hurdle", on the one side, meets "we want to sell this thing and need the certification" on the other.

Scientists will always say "wait a minute, were not sure". Institutions and their structures leave little room for this, so scientists get translated to certainty rhetoric, and the gullible public who often has a quasi-religious view of science swallows it, as that's how the media makes it for them.
