There is a fallacy that is very common in public discourse when you bring up the idea of conspiracy ( I mean the word in it's most literal sense , in that a group of people worked in a clandestine and coordinated fashion in order to achieve this or that end ), that it simply could not be possible because EVERYONE would have to be in on it .

Such an innocent view of the world, it would be nice if things were that decentralised, but alas...
