And this has nothing to do with anything, but it does set my teeth on edge:
If you say something has a “three-fold increase”, it does NOT mean that you are multiplying the increase by three or that the increase is 300%.
Take a piece of paper. Fold it in half. You have two layers. Fold it again, and you have four layers. Fold it a third time, and you get EIGHT layers.
That’s right: “something-fold” is supposed to be exponential, not multiple.
And really, it seems to be such a small thing, but it makes me a little crazy. Please, use your folds wisely.
This rant was inspired by a single line of urk in this very excellent article on HOW healthcare has become so goshdarn expensive.
