No matter how true it seemed for a couple hundred years, eventually, more information came to light, and showed it was not true.
How many beliefs do we currently hold that are untrue? In Banana's case it's obviously zero, but I'm speaking of scientific beliefs (or "Facts" if you will). I hazard it's a value close to 100%.
