I've heard that The Flat Earth society is increasingly popular, with members around the globe now.
A sound piece of advice I was given once is thus:
It’s easy to think you can do a better job than someone else.
When you see people doing seemingly dumb things, it’s wise to assume they may know something you don’t.
I always put my faith in the people with the best possible experience / qualifications in their field, not those who shout the loudest.
