Beware false ranges

“The new BMW 500 arrives loaded with cutting edge technology, everything from in-dash GPS to electronic stability control.”

Did you spot the problem with this sentence? It suffers from a common communication fault called a false range. These sentences usually take the form of “everything from ‘A’ to ‘B’.” The problem arises when the reader has no way of knowing what comes between A and B.

In our example, the reader can guess which technologies are in the new BMW, but it’s unlikely that the car really has every automotive technology available.


To avoid false ranges, be certain that the reader can fill in at least some if not all of the missing elements. For example, “Acme Bike Repair is ready to handle everything from fixing a flat to restoring a 1895 Schwinn Roadster.” Anyone reading this gets the clear message: When it comes to your bike, Acme can fix it.

In most cases, however, the better solution is to make it easy on the reader. “The new BMW comes loaded with cutting edge technology, including in-dash GPS, speed- sensitive airbags, blind spot alarms, rear-view camera and electronic stability control.
