That's not to say that science is always "right". In the wake of something new (like COVID), new scientific evidence is going to come piecemeal and incomplete. And I do believe that there are long-held dogmas that CAN be overcome. But the chances become less and less of this the more a field is studied. It's like an open-source SW project that gets better and better over time... You've got to be REAL good to find the flaws in the system.
