The passive voice is a favorite of academics (“A study was conducted…”), politicians (“Mistakes were made…”), business memo writers (“The shipping department will henceforth be outsourced…”) and other communicators we love to hate. Indeed, the passive voice causes a lot of heartache for readers and writers alike. Somewhere along the line, you have probably been told to avoid passive voice. That’s not bad advice, except for the fact that sometimes the passive voice is exactly what you need. I just used it, in fact, in the sentence before last.
“Avoid passive voice” is a helpful rule of thumb; but it’s only a rule of thumb. The deeper rule is this: Make active voice your default. And the rule has this corollary: Use passive voice only when you have a good reason to.
