Size does make a difference, but not in the way you’re thinking. Do you know the difference in a small, medium and large soda, order of french fries or skirt? Probably not, other than they do differ in size. There are no uniform standards when it come to commodities like these, and manufacturers and food retailers can create their own.
But here’s a fascinating study
A marketing professor at the University of Michigan discovered, while studying the effects of sizes on labels, that we are pretty easily duped. The study involved cookies–one set labeled “medium” the other labeled “large.” In reality, the cookies were the same size. But researchers noted that people ate more of the medium cookies, because they believed the were eating less calories. According to NPR online, rather than trust what their stomachs were telling them, in other words, people went by the label.
While most of us who were around 50 years ago remember when a small of any drink was 8 oz., we may not realize that a large soda today is actually six times bigger than ones of yesteryear. Six times, according to the Centers for Disease Control.
I know this has happened with clothing, because I have several dresses of my mother’s from the 1960s that are labeled size 8 and are smaller than a size 2 today. It’s called vanity sizing, and the fashion industry has been doing it for decades. Soon we’ll all be wearing clothes in the negative digits and drinking small diet Cokes that are actually 32 oz.
