Results that are too good are simply implausible. But while these guys were stupid, they weren't evil.
In the recent Iranian elections, former jailed reporter Amir Taheri noted:
Mr. Ahmadinejad was credited with more votes than anyone in Iran's history. If the results are to be believed, he won in all 30 provinces, and among all social and age categories. His three rivals, all dignitaries of the regime, were humiliated by losing even in their own hometowns.
The statistical probability the sample variance is this small is effectively nil.
I don't want my own fatwa, but I'm skeptical. Perhaps this is a good marketing pitch for statistics professors. Even if you are an evil dictatorship, it pays to know some statistics!
