“The Devil is in the Digits” is an article that attempts to explain why the Iranian vote count may be fraudulent. It has to be one of the more bizarre things written about this election. The premise is that it is difficult for people to make up numbers. So if numbers are made up, they will have a disproportionate frequency. Either too many or too few. I cite:
The numbers look suspicious. We find too many 7s and not enough 5s in the last digit. We expect each digit (0, 1, 2, and so on) to appear at the end of 10 percent of the vote counts. But in Iran’s provincial results, the digit 7 appears 17 percent of the time, and only 4 percent of the results end in the number 5. Two such departures from the average — a spike of 17 percent or more in one digit and a drop to 4 percent or less in another — are extremely unlikely. Fewer than four in a hundred non-fraudulent elections would produce such numbers.
Oh, hooey. Any good cheater knows that you don’t make up the beginning numbers or the ending numbers, you make up the middle ones. The authors practically refute their own assertion when they compare Obama and McCain’s results and tell you “ The frequencies of last digits in these election returns never rise above 14 percent or fall below 6 percent,…” Oh, perhaps I should get excited by a 3% difference between Obama and Ahmadenijad’s results but I just cannot.
But that’s not all. Psychologists have also found that humans have trouble generating non-adjacent digits (such as 64 or 17, as opposed to 23) as frequently as one would expect in a sequence of random numbers. To check for deviations of this type, we examined the pairs of last and second-to-last digits in Iran’s vote counts. On average, if the results had not been manipulated, 70 percent of these pairs should consist of distinct, non-adjacent digits.
Not so in the data from Iran: Only 62 percent of the pairs contain non-adjacent digits. This may not sound so different from 70 percent, but the probability that a fair election would produce a difference this large is less than 4.2 percent. And while our first test — variation in last-digit frequencies — suggests that Rezai’s vote counts are the most irregular, the lack of non-adjacent digits is most striking in the results reported for Ahmadinejad.
This kind of logic must be trendy and fashionable. I see it often. I suppose I should get all googly-eyed and go “oooooohhh” but I can’t. (Or alternatively: OMG, its is 62% instead of 70%! The sky is falling !)
Well, we should all have deduced by now that this article has as much truth in it as the The DaVinci Code and National Treasure movies. I might even believe that is where the idea came from….62% of the time.
And, finally, does anyone think that “generating non-adjacent digits (such as 64 or 17, as opposed to 23) as frequently as one would expect in a sequence of random numbers” might just be an English language issue that does not exist in Farsi? If anyone can show that these made-up-number theories are true for multiple languages, let me know.
Call me skeptical on this …about 62% of the time based upon the frequency of the letter ‘e’ in this posting which represents a 2-3% deviation from accepted blog postings on other topics unrelated to actual vote fraud.
