Are you familiar with Benford's Law?
It is a wya of determining with high probabilities whether a given data set is organically or naturally occurring, or if it was manipulated or thought up by a person. It's very good at detecting human influence in a data set. That's because humans act and think differently than nature. If you tell a man to generate a random number, it won't be random. There will always be hallmarks of human intervention in data.
Now you know something that you didn't know before.
And would you like me to show you precinct reporting results that trip every single red flag in benfords law?
