I’m currently reading Stephen King’s book On Writing and within his Toolbox section he discusses passivity through writing:

Verbs come in two types, active and passive. With an active verb, the subject of the sentence is doing something. With a passive verb, something is being done to the subject of the sentence. The subject is just letting it happen. You should avoid the passive tense…. I think timid writers like them for the same reason timid lovers like passive partners. The passive voice is safe. There is no troublesome action to contend with; the subject just has to close its eyes and think of England, to paraphrase Queen Victoria.
The timid fellow writes The meeting will be held at seven o’clock because that somehow says to him, “Put is this way and people will believe you really know.” Purge this quisling thought! Don’t be a muggle! Throw back your shoulders, stick out your chin, and put that meeting in charge! Write The meeting’s at seven. There, by God! Don’t you feel better? (page 123)
