Greetings!
About 600 years ago it was common knowledge that if you sailed west from Europe, either the ocean would abruptly end and you would fall off the end of the earth, or there were man-eating dragons waiting for you for lunch. Their lunch, not yours. (See our note about this in our PS.)
People living in that era had it tougher because the facts themselves were in short supply. Today there are enough facts around to satisfy everyone if they bother to look.
That’s why it’s so amazing that misinformation still spreads even amongst professionals in a field.
