Summary: The Corona virus situation has seen an explosion in wild conspiracy theories. How many can be “in on it” in a conspiracy before it breaks?
“If you want to keep things a secret for five years, have less than 2,531 people in on the plot. If you’re shooting for a decade, 1,257 is the largest you can go. And if you want to have a conspiracy that lasts a century or more (like the DaVinci Code) then you need to keep your numbers really small, down to 125 people.”
