Science, as the Islamic mathematician and empiricist al-Haytham (965 to 1040 A.D.) is not done by mere head count:
“The seeker after truth does not put his faith in any consensus, however venerable or widespread. Instead he questions what he has learned of it, applying to it his hard-won scientific knowledge, and he inspects and inquires and investigates and checks and checks and checks again. The road to the truth is long and hard, but that is the road we must follow.”
