Zombie Metric Reform

by The Metric Maven

In recent months, numerous media stories have discussed a market phenomenon called shrinkflation. National Public Radio (NPR) had a segment called Shrinkflation: Inflation’s Sneaky Cousin. Edgar Dworsky, a long-time consumer advocate, who had been an Assistant Attorney General in Massachusetts, has been tracking shrinkflation on his website. (And, of course, there’s a subreddit for shrinkflation). Edgar noted that a grocery store had replaced all the old General Mills cereal boxes with newer ones. He found some of the earlier boxes on an end display, and selected an old box of Cocoa Puffs. He returned to the main aisle, and put the old box next to the new one. General Mills had downsized the contents of their “Family Sized” box from 547 grams to 513 grams. Edgar took both boxes to the price scanner, and they both scanned the same price. This is very similar to real fraud.

Shrinkflation is where a company reduces the amount of contents in a box, and charges the same price—or even more. NPR’s Planet Money seems to be reporting this problem in a farcical tone (after NPR had injected two commercials). The “reporters” said that inflation is “old news” and skrinkflation is “brand new.” Edgar Dworsky has catalogued dozens of examples of shrinkflation over the years, including Maxwell House Coffee, Tropicana Orange Juice, Tuna Cans, Peanut Butter Jars….etc.

Dworsky diagnoses why this tactic works:

Because consumers are not net weight conscious, they’re price conscious but not net weight conscious. It is a sneaky way to pass on a price increase.

The presenters point out that if human beings followed the classical economic assumption, that they are rational consumers, then this should not be a successful tactic.

Planet Money reached out to General Mills for an explanation. Here is GM’s reply:

The change is all about creating consistency and standardization across the cereal products. [This allows] much more efficient truck loading, leading to fewer trucks on the road, and fewer gallons of fuel used, which is important in both reducing global emissions as well as offsetting increased cost associated with inflation.

As Dr Sunshine used to say, “I have two words to describe this: bull and shit.” Well, its not much of a standard if the amount can be changed in a capricious manner. The consistency is only in making uniform stealth changes. Oh yes, and if you buy this line of BS, then you will also believe General Mills is saving the planet one reduced sized quantity at a time.

Edgar Dworksky does not. He points out that you will run out of cereal sooner, and go to the supermarket sooner than expected, to replenish your Cocoa Puffs, and use more cardboard. Planet Money’s view is that hey,

…to be fair to General Mills, like a lot of companies these days they are dealing with increased business costs, you know higher gas, higher cost of grain, and shrinkflation is their way of dealing with it.

Spoken like a truly fair man, who accepts corporate humbug, as long as its in the open, like a magical illusion that fools everyone—so no one is hurt. Thank you for setting us straight propagandist Greg Rosalsky, who continues to chuckle as he moves along in jovial dialog with Stacey Vanek Smith. This not an intellectual fraud, it’s just business. The consumers don’t realize they’re being taken—and that’s ok today—and fun to talk about.

So what does all this have to do with metric reform? Well here is a quotation from Metrication in Australia:

In hindsight, the early conversion of quantity statements on packaged goods and changes in package sizes had an insignificant impact on public education due largely to the universal existence of the supermarket method of marketing, in which packages were selected by the customer by visual size rather than by quantity name in either imperial or metric.

The US Metric Association, and Elizabeth Benham at NIST, are apparently convinced that if we finally allowed all 50 states to present metric labeling on products, suddenly consumers would embrace an understanding of metric values. This idea has been discussed over and over. Clearly, business understands that people are often not only innumerate, but worse, substitute perception for quantification. It is a belief in the existence of a rational “classical economics” consumer, who will then “punish the market” into relenting, that is at the heart of this flawed notion. During their metric switch-over, Australians learned that metric labeling in supermarkets, as an educational tool, was a fiction. Even with overwhelming practical evidence, as shown by the implementation of shrinkflation across essentially all consumer goods, will these metric advocates rethink and redirect their efforts? This view is a zombie idea that entrances and then eats the brains of some metric advocates. No matter how many times I point this out, the zombie idea arises again, as a parasitic red herring that wastes people’s time and intellectual effort. Please, put salt in this zombie idea’s mouth, and sew it shut.

Mnemonic Metric Prefixes

Years ago, my friend Ty took an interest in how to remember information. He pointed out that often you will think of something you want to do or retrieve, leave the room where you made the decision, and by the time you arrive in the next room, have forgotten. Often you return to the the original room, and then suddenly can recall what you meant to retrieve or view. Ty asserted it was because you had associated the decision with the original room, and when you returned, the two things were attached in your mind and you immediately recalled why you left in the first place. Years ago, when I was a young boy, people would tie a string around their finger to remind them to remember an important piece of information.

When I was taking trigonometry in high school, the teacher indicated we should remember words and phrases to recall the definitions of the sine, cosine, and tangent of a right triangle. He offered:

The adjacent side of the triangle was closest to the angle, the opposite side was well, opposite of the angle, and the hypotenuse was the long side that was not the others. Silly Cold Tigers? and Oscar Had A Happy Old Aunt?—how ridiculous!—but decades later, I still remember this method of recalling the definitions of the basic trigonometric functions of a right triangle. He encouraged his students to make up their own, and indeed they came up with more memorable phrases that were the sort that teenage boys were more likely to remember.

A number of “metric advocates” have ridiculed my assertion that grade school children, middle school students, and high school pupils, should be instructed in the use of all the metric prefixes. In my view, all the prefixes means the eight magnifying and eight reducing prefixes separated by 1000. One of the most effective instructive methods for recalling information is the use of a mnemonic device. Here I propose a pair of these, one for the magnifying prefixes, and one for the reducing prefixes. The first mnemonic is presented in the table below for the magnifying prefixes:

The mnemonic phrase for the magnifying prefixes is: “Kilroy Might Get To Paris Escorting Zombies Yonder.” The first letter of each word corresponds to the prefix symbol. The first prefix is Kilo is suggested by the name Kilroy, but the rest of the prefixes all end with an “a.” This can be thought of as the prefixes “above” unity.

The second table for the reducing prefixes is:

The mnemonic phrase for the reducing prefixes is “Millie might not protest fetching another zesty yeti.” Again the first letter of each word corresponds to the prefix symbols except for micro. The student would have to spell out micro and then recall the μ symbol is used, rather than another m. The first word is again a name, Millie, which in this case contains the spelled out prefix. Again means we need to forget it, but realize the reducing prefixes all end with “o” and are “below” unity.

In both cases the phrase begins with a name, and involves that person compelling mythical creatures.

If students were taught these mnemonics from perhaps grade 6 or 7 onward, with metric prefix examples, like those found in The Dimensions of the Cosmos, by the time they graduated from high school, they could have the tools needed to recall the metric prefixes without a textbook, and be reminded to use them in their work.

I would be interested in any comments or suggestions readers might have about these proposed mnemonic devices that might improve them. The best way to promote their use would be for the US to become a mandatory metric nation, but as this country celebrates its reactionary nature with religious fervor, I’ll have to settle for whatever good these mnemonics might do without a change.
