if democracy was not possible, how does it come that the greek did democracy and it is said they were once overrun in a war because of beeing democratic? if something was a cause for a turn of a war, i pretty much believe it to really exist, no matter what some kind of half baked formulars "predicted" once.

if democracy existed and your math says thats not possible, i'ld guess your math might simply be 'slightly' wrong about it or was created with (un-)intentional biases in mind ;-)

just to note:

in the history of human predictions based on thought through and wordly/mathmatically described rules, the most common thing afterwards was, that those rules and also their predictions were just fundamentally wrong and biased.
