The Mathematical Improbability of Large Conspiracy Theories
One of the points we have always tried to make here is that although conspiracies certainly happen, any conspiracy more complex than a burglary or assassination involving half a dozen people inevitably becomes exposed. The Truthers on the other hand create these theories involving the ridiculously complex cooperation of thousands of people across dozens of different organizations, often for no other reason than that they need it to be so in order to fit their pet theory.
A British academic explores this fact in more scientific terms:
If you’re thinking of creating a massive conspiracy, you may be better scaling back your plans, according to an Oxford University researcher. While we can all keep a secret, a study by Dr David Robert Grimes suggests that large groups of people sharing in a conspiracy will very quickly give themselves away. The study is published online by journal PLOS ONE.
