Writing Consistently in Third Person (and Tense)

Third person isn't hard to write for a sentence or two. It falls apart over three pages, when a writer who started in "the researcher observed" drifts into "we found" by paragraph four without noticing. Consistency, not the initial choice, is where this actually breaks down.

Why the Drift Happens

Third person requires constantly translating your own actions into an external description: not "I tested three groups" but "the study tested three groups" or "three groups were tested." That translation gets tiring over a long document, and writers unconsciously slip back into the more natural first person once they're deep in a train of thought, especially in sections describing their own reasoning rather than neutral facts. This isn't laziness, it's a genuinely awkward habit to maintain consistently without deliberate effort.

A Practical Fix

Do a dedicated pass, separate from your regular editing, that only checks for pronoun consistency. Search your document for "I," "we," "my," and "our" if you're writing in third person, and for each instance decide whether it's an actual violation or a legitimate exception your assignment allows (some fields now permit "I" specifically in methods sections, discussed in more depth in APA's guidance on first-person pronouns). Fixing this in one dedicated pass is far more reliable than trying to catch it while also checking grammar, structure, and content simultaneously.

Tense Consistency Has the Same Problem

A related and equally common drift: switching between past and present tense mid-paragraph without a reason. "The author argues that inequality drives instability. She presented three case studies to support this" mixes present ("argues") with past ("presented") for no clear reason. Academic convention generally uses present tense for discussing what a text or theory claims ("the author argues"), and past tense for describing specific historical events or completed research actions ("the study collected data in 2019"). Pick the right one for each type of claim and stay consistent within that category throughout.

A Small Example

Weak: "The company launches its new product in March, and it was well received." Consistent: "The company launched its new product in March, and it was well received." Once you're describing a specific, completed event, stay in past tense for that entire thread of narration, even if you switch to present tense elsewhere to describe the theory or argument the event illustrates.

Why This Matters More Than It Seems

Inconsistent person or tense doesn't usually confuse the reader about facts, but it does read as unpolished, and it signals a document that wasn't fully proofread. It's one of the fastest things a careful reader notices and one of the easiest to fix once you know to look for it specifically, rather than trusting it to surface during a general reread focused on content instead of these mechanical patterns. UNC's writing resources are worth a look for a few more examples of this specific kind of drift. It's also worth checking Purdue OWL's guide to academic writing if your document mixes description of past research with ongoing analysis, since that combination is exactly where tense drift tends to sneak in unnoticed, one paragraph describing what a study found and the next describing what it means without a clear tense shift marking the transition. Checking your usage against Merriam-Webster won't catch tense drift directly, but it's still useful for confirming the specific verb form you land on is standard once you've decided which tense a given sentence belongs in. If your document also mixes first and third person alongside the tense shifts, Grammarly's explanation of passive voice is a useful adjacent read, since passive constructions are often what writers reach for when they're trying to avoid deciding on person and tense at the same time.
