Making Up The Numbers

Many of the scary numbers we get from the “experts” are wrong, overstated, and in far too many cases, invented. They are ass numbers – numbers someone pulls out of their ass and then spews with authority. “Journalists” then print these ass numbers as if they’re real, but cover their own butts with the weasel words “according to.” “According to Dr. Bigshot McExpert drinking coffee causes a 34% increase in foot fungus.” Other “journalists” copy the story, repeating the claims. Rinse, lather, repeat and sooner or later, usually sooner, most of the public is confident in their knowledge of facts that aren’t facts at all.
This is rampant in the field of medicine, especially in medical claims used to create public policy and laws. It’s even more rampant in economics. Most economic estimates, projections and claims are just fanciful guesses designed to cause alarm where none is warranted.
Experts rely on ass numbers because they almost always get away with it. They’re seldom called on their claims. When they are, the results are usually enlightening and entertaining.
When blogger Michael Geist asked the Canadian police for proof of their claim that software piracy costs Canada thirty billon dollars a year, they said they, well, um, er, kinda sorta. . . made it up. They got their information from an industry front group that generates ass numbers for a living, and then repeated it. They also did some math, again picking random numbers for their calculations. You can read Michael’s story here.
Here’s a fun project for a rainy weekend. Scan the news for ass numbers. Pick one that seems really outrageous. If you like, you can do some research on your own to see if there’s any truth to the number, or even to find out what the real number should be, but that’s optional. Now send some e-mail to the reporters who wrote the story and any sources quoted in the article. Ask for specific sources of the numbers.
Some people will ignore you. Most who reply will evade the question. Persist. Ask them again. Be polite for at least the first few exchanges. You’ll learn a lot about trusting numbers from the experts.
A while back I did just that with ten different nicotine nanny organizations and individuals. You can read the results here.
