Active vs Passive Voice: A Before-and-After Rewrite of a Lifeless Paragraph

Most “lifeless” writing isn’t lifeless because the ideas are dull. It’s lifeless because nobody’s doing anything in the sentences. The actors got buried, the verbs went limp, and the whole thing reads like a memo about a memo.

That usually comes down to one fixable habit: passive voice on autopilot. Below is a real before-and-after rewrite, plus a few rules you can actually remember.

Key takeaways

• Active voice names who does what, in that order: subject, verb, object. Passive flips it and often drops the doer entirely.
• Passive voice isn’t a grammar error. It’s a tool you should use on purpose, not by default.
• Quick check: if you can add “by zombies” after the verb and it still makes sense, you’re in passive voice.
• Going active usually shortens the sentence, demands a real subject, and forces you to be specific. That’s what makes prose sound human.
• Keep passive when the doer is unknown, irrelevant, or when you genuinely want the focus on the thing being acted on.

What active and passive voice actually mean

Active voice puts the doer first. “The committee approved the budget.” Somebody did something to something. You know exactly who, what, and to what.

Passive voice rearranges that. “The budget was approved by the committee.” Same facts, but now the receiver of the action comes first and the doer trails behind a “by.” And here’s the sneaky part: passive lets you drop the doer altogether. “The budget was approved.” By whom? The sentence doesn’t say, and sometimes that’s the whole point of using it.

So passive voice has two flavors. There’s the honest kind, where you genuinely don’t know or don’t care who acted. And there’s the evasive kind, where the doer got vanished on purpose or by accident. The second kind is what makes paragraphs feel like wet cardboard.

The zombie test

If you want a test you’ll actually remember, use this one. Add “by zombies” right after the verb. If the sentence still works grammatically, it’s passive.

• “Mistakes were made by zombies.” Works. Passive.
• “The data is being analyzed by zombies.” Works. Passive.
• “Our team analyzed the data by zombies.” Nope. That one’s active.

It’s silly, which is exactly why it sticks.

A real before-and-after rewrite

Here’s a paragraph in the style of a thousand status updates. It’s grammatical. It’s also dead on arrival.

> Before: It was decided by management that the rollout would be delayed. Concerns had been raised by several team members regarding the testing timeline. After the risks were reviewed, a revised schedule was agreed upon. Stakeholders will be notified once the changes have been finalized.

Read that out loud. Notice how you can’t tell who’s actually steering anything. Management “decided,” sure, but after that everyone vanishes. Concerns “had been raised” by a fog of “several team members.” Risks “were reviewed” by ghosts. It’s four sentences and roughly the same flat note four times.

Now the rewrite. Same facts, nothing invented, just the doers put back where they belong.

> After: Management delayed the rollout. Several engineers had flagged the testing timeline as too tight, so we reviewed the risks and agreed on a new schedule. We’ll tell stakeholders once the changes are final.

Three sentences instead of four. The word count dropped by about a third. And you can actually picture the room now. Management made a call. Engineers pushed back. A team reviewed and decided. Somebody will send an email.

Notice what changed mechanically:

• “It was decided by management” became “Management delayed.” The doer moved to the front, and “it was decided that” evaporated, since it was just throat-clearing.
• “Concerns had been raised by several team members” became “Several engineers had flagged.” Vague “team members” became “engineers.” The verb got stronger.
• “A revised schedule was agreed upon” became “we… agreed on a new schedule.” A real “we” showed up.
• “Stakeholders will be notified” became “We’ll tell stakeholders.” Shorter, warmer, and you know who’s sending it.

I kept one near-passive construction on purpose: “once the changes are final.” Nobody cares who finalizes them, and naming a doer there would clutter the line. That’s the deliberate kind of passive, and it earns its place.

Why this matters beyond style

Two things happen when you trade chronic passive for active, and they feed each other.

First, your sentences get more varied. Passive constructions tend to be long and similar in shape, all leaning on “was” plus a participle. When you go active, some sentences shrink to four words and others stay long, and that mix of lengths is most of what readers feel as rhythm. If you want the under-the-hood version of why uneven rhythm reads as human, our breakdown of how AI detectors actually work digs into the signals they lean on. The short version: flat, predictable prose is exactly what both bored readers and detection tools react to.

Second, active voice forces honesty about who did what. You can’t write “Management delayed the rollout” without committing to the claim that management, specifically, made that call. Passive voice is the language of dodged responsibility precisely because it lets the doer hide. Put the actors back, and the writing gets clearer and harder to weasel out of at the same time.

That second effect is worth a beat. A lot of what people call “AI-sounding” writing is really just confident-but-empty prose, and passive voice is one of its load-bearing walls. Machines reach for it because it’s safe and agentless. Restoring the actors is one of the fastest ways to make a draft sound like a person actually stands behind it.

When passive voice is the right call

Don’t go on a search-and-destroy mission. Some sentences genuinely want passive voice, and forcing them active makes things worse.

• The doer is unknown. “The lab was broken into overnight.” You can’t name a thief you haven’t caught.
• The doer is irrelevant. “The samples were stored at four degrees.” Who put them in the fridge doesn’t matter. The temperature does.
• You want the focus on the receiver. “The bill was signed into law.” The bill is the story here, not whose hand held the pen.
• You’re softening an accusation. “The form wasn’t submitted on time” is sometimes kinder and smarter than naming the person who missed the deadline.

Notice these are all choices. You looked at the sentence, decided the doer wasn’t the point, and used passive on purpose. That’s the difference between a tool and a tic.

A quick self-edit pass

When you reread a draft, do one targeted sweep:

1. Search for “was,” “were,” “been,” and “being.” Most passive voice hides near one of those.
2. For each hit, ask: do I know who did this? If yes, try fronting the doer and see if the sentence gets better.
3. If you don’t know the doer, or it truly doesn’t matter, leave it. That’s earned passive.
4. Read the paragraph aloud. Wherever your voice goes monotone, you’ve probably stacked too many similar constructions in a row.

This takes a few minutes and catches most of the damage.

If you’re weighing whether the tool side of this is worth it, you can compare the plans before you commit to anything.

Frequently asked questions

Is passive voice grammatically wrong?

No. Passive voice is perfectly correct grammar. The issue isn’t legality, it’s effect. Used constantly and without thinking, passive voice hides who’s doing things, pads sentences with extra words, and flattens the rhythm of a paragraph. Used on purpose, it’s a precise tool. The goal isn’t to delete every passive construction; it’s to notice when you’ve slipped into passive out of habit and ask whether active would be clearer.

How do I spot passive voice quickly?

Two quick tests. First, look for a form of “to be” (is, was, were, been, being) paired with a past participle, like “was decided” or “is being reviewed.” Second, the zombie test: if you can add “by zombies” after the verb and it still parses, you’ve found passive voice.

When should I actually use passive voice?

When the doer is unknown (“the window was broken overnight”), when the doer doesn’t matter (“the samples were stored at four degrees”), or when you want the spotlight on the receiver of the action (“the bill was signed into law”). Science, legal, and incident writing lean passive for good reasons. The trick is choosing it, not defaulting to it.

Does active voice help my writing pass an AI detector?

Indirectly, yes. Detectors react to predictability and flat rhythm, and chronic passive voice produces both. Switching to active usually shortens sentences, varies their length, and forces concrete subjects, which raises the variation a detector reads as human. Keep in mind that detectors output a probability, not proof, and they get things wrong. So treat active voice as a writing improvement first. The cleaner detection score is a side effect of clearer prose, not a trick.

Will a grammar checker fix passive voice for me?

It’ll flag it, which helps, but it won’t make the call for you. A checker can’t tell whether a given passive is the lazy kind or the deliberate kind, and it can’t supply the missing doer, because only you know who acted. Treat the flag as a prompt to reread, not an order to rewrite.

The bottom line

Active voice isn’t a rule you follow because an English teacher said so. It’s the fastest way to put people back into your sentences, cut the dead weight, and make a paragraph sound like someone wrote it on purpose. Fix the worst offenders, keep the passive sentences that earn their spot, and read the thing out loud.
