How The Media Exaggerates to Scare You — Often In Support of Growing the State

Posted by on | June 23, 2017 | Comments Off

I find the WSJ to be more readable than most modern newspapers, but that does not mean it doesn’t play exactly the same silly media games every other media outlet does.

This article is about a legitimately dangerous dam in California that is being rebuilt to accommodate new learning about how earthen dams behave in seismic events.  The authors attempt to extrapolate from this example to highlight a larger threat to the nation.  They use this chart:

A reader who is not careful and does not read the fine print, which means probably most all of them, will assume that “dangerous” and “hazardous” as used in this chart refers to dams that are somehow deficient.  But in fact, these terms in this chart refer only to the fact that IF a particular dam were to fail, people and property might be at risk.  The data here say nothing about whether these dams are somehow deficient.  Actually, if anything, I am surprised the number by this definition is as small as 30%.

The actual number of deficient dams that are dangerous to human life is actually an order of magnitude smaller than these numbers, as given in the text:

An estimated 27,380 or 30% of the 90,580 dams listed in the latest 2016 National Inventory of Dams are rated as posing a high or significant hazard. Of those, more than 2,170 are considered deficient and in need of upgrading, according to a report by the American Society of Civil Engineers. The inventory by the U.S. Army Corps of Engineers doesn’t break out which ones are deficient.

So if we accept the ASCE numbers as valid (and I am always skeptical of their numbers, they tend to exaggerate in order to try to generate business for their profession) the actual numbers of dams that are really hazardous is no more than 2,170.  That strikes me as a reasonably high number, and certainly a good enough reason to write a story, but the media simply cannot help themselves and insist on exaggerating every risk higher than it is.
