We now use the scientific method to argue ideas, but in the past ideas could just be laughed at if people thought they sounded dumb. People laughed at ideas like the sun being the center of the solar system and doctors needing to wash their hands before surgery. Refusal to accept these ideas held humanity back from technological advancement.

People didn’t just laugh at those ideas, they actively punished the people who proposed them.
