Active vs Passive Voice: When Passive Actually Works

"Never use passive voice" is bad advice stated as a rule. Passive voice isn't a grammar error. It's a tool that happens to get misused often enough that people started treating the tool itself as the problem.

The difference is simple: active voice puts the doer first ("the committee rejected the proposal"), passive voice puts the receiver first ("the proposal was rejected by the committee," or even "the proposal was rejected," dropping the doer entirely). Active is usually more direct and easier to read, which is why it's the safer default. But "usually" isn't "always," and knowing the exception matters as much as knowing the rule.

When Passive Is Actually the Better Choice

Passive voice earns its place when the doer is unknown, irrelevant, or deliberately being downplayed for a legitimate reason. "The bridge was built in 1932" works fine in passive because nobody's asking who specifically laid each beam. In lab reports and methods sections, passive constructions like "the samples were heated to 80 degrees" are often preferred precisely because the focus belongs on the procedure, not on the individual researcher performing it, though this convention varies by field and has been loosening in recent style guidance.

The Real Problem With Passive Voice

The actual issue isn't passive voice itself, it's passive voice used to hide responsibility. "Mistakes were made" is the textbook example: it describes an event while carefully avoiding who caused it. That's not a grammar failure, it's an evasion, and readers usually sense it even without naming the grammatical trick behind it. Grammarly's explanation of passive voice covers the mechanical difference clearly, but the sentence-level fix is less about grammar and more about being willing to name who did what.

A Quick Diagnostic

Search your draft for "was" and "were" followed by a past participle: "was decided," "were implemented," "was found." For each one, ask if naming the actual agent would make the sentence stronger or just longer. If a name or actor genuinely improves the sentence, switch to active. If the doer really doesn't matter to the point you're making, passive is a legitimate choice, not a mistake you forgot to fix.

A Small Example

"The report was reviewed and several errors were identified" is passive twice over, and it's vague about who did the reviewing. "The audit team reviewed the report and found several errors" is more direct, and it also happens to be more useful information if the reader wants to know who to ask follow-up questions. Compare both versions out loud; the active one almost always sounds more confident, which is usually the deciding factor once the actual meaning is preserved either way.

Passive voice isn't the enemy. Passive voice used to avoid a question you don't want to answer is the actual problem, and that's worth catching regardless of which voice you're technically writing in. If you're working in a discipline where passive constructions are still the convention for methods sections, APA's guidance on first-person pronouns is worth reading too, since it covers the related question of when active, first-person phrasing has become acceptable even in traditionally passive-heavy fields. And once you've decided which sentences to convert, a broader look at Purdue OWL's academic writing guide helps place the active-passive choice inside the bigger picture of writing clearly for an academic audience. If your sentence's subject is a term with a precise technical meaning in your field, double-check it against Merriam-Webster before you commit to naming it directly in an active construction. When the sentence itself is drawn from a source you're paraphrasing, UNC's paraphrasing guide is worth checking too, since converting a passive original into an active paraphrase is a common way meaning quietly shifts during revision.
