The qualifications in those days were found in the Holy Bible.
From what I'm hearing, apparently while you are not capable of reaching an independent conclusion on a variety of subjects based on the info the experts present, whether Ivermectin or masks, who are certain capable of determining who is an expert and who is a good expert that should be listened to and who is not, particularly if said person is in the majority.
Typical of the meritocracy.
Part of the problem with experts is they don't have full information. So the epidemiologist with masks may not have the background in child psychology, the environment, or engineering to make a valid recommendation. Same with shuttering schools. Experts are so siloed, if you want to make policy based on expertise, deferring to 1 individual aint a way to do it.
