The REALLY smart people are the ones who say “I’m not really sure ...” about stuff.
The dumb people are the ones who say, “Shut up, I’m an expert.”
The “smart” people have the letters after their names and get government positions and contracts. That’s why the “smart” people love big government and pretend to believe in the global warming doomsday cult. IMHO this is mammon (faith or devotion to money to the point that to get it, you “believe” the unbelievable or do the unholy).
