Statistics can lie, not because they are incorrect but because they are partial, incomplete, so that sometimes what is unreported is the real fact that’s needed to see things realistically. Still, they can be interesting—and revealing. As these are, I think:

Let’s begin where we should, by reminding ourselves that statistics must be used carefully, with a healthy bit of skepticism. Not that numbers necessarily lie, but they only tell part of the truth and the part they don’t tell might be the part that’s of primary significance. “Then there is the man,” W. I. E. Gates notes, “who drowned crossing a stream with an average depth of six inches.”

Funny, but I can’t find anything about a W. E. I. Gates. But being of German/Dutch heritage I do know that wie gehts in German is a common greeting meaning, “How’s it going?” so even that… Anyway, on to a few of the numbers I’ve found worth some reflection.

Number of U. S. prisoners freed between 1989-2007 through DNA evidence—201. The number of those prisoners that had been (mistakenly) identified by eyewitnesses—77%.

Amount of money estimated by researchers at the University of California (San Diego) earned by an email Viagra spammer—approximately $7000/day.

When President Obama nominated Elena Kagan to the U. S. Supreme Court, the National Archives were responsible to release all documents relating to her work while in government service. Turns out she had received 50,000 pages of documents from the Domestic Policy Council (where she had been deputy director) and 30,000 from the Counsel’s office (where she was associate counsel). During this period she sent 11,000 pages of emails and received 68,000 pages. The estimated total comes to around 160,000 pages of documents. This represents four years of government service.
