How to Use Tenses Correctly in a Research Paper

Tenses in Research Paper

The correct tense in a research paper depends on the section you're writing, using present tense for established knowledge, past tense for completed actions, and present perfect for ongoing scholarly discussions. Before we examine these conventions in depth, it’s worth noting that tools like Scifocus can greatly streamline academic writing by helping you refine grammar, structure, and scholarly tone.

Why do research papers require specific verb tenses?

The answer is straightforward: research writing relies on tense to express temporal relationships with precision. Academic convention has long treated tense as a structural element—one that signals what is known, what has been done, and what is yet to be interpreted. As noted by established writing authorities such as the Purdue OWL guidance on verb tenses, tense communicates whether a claim reflects general knowledge, a prior action, or an evolving field of study.

Research writing therefore uses tense not merely for grammatical correctness but for conceptual clarity. It helps readers track the methodological timeline, contextualize findings, and situate arguments within existing literature.

Which tenses are most commonly used in research papers?

Research papers primarily use present simple, past simple, and present perfect, each serving a distinct rhetorical purpose. Present simple articulates enduring facts: “The dataset contains four variables.” Past simple reports completed actions: “Researchers collected survey responses.” Present perfect highlights scholarship that continues to influence the field: “Studies have examined the correlation between feedback and performance.”

Academic organizations such as the APA Style guidelines outline similar distinctions, emphasizing how tense supports clarity and scholarly accuracy.

When is past tense required in a research paper?

Past tense is required whenever the research refers to actions that have already been completed. This includes experimental procedures, study contexts, analytical processes, and empirical outcomes. For example: “The survey was administered during the spring semester.” Such usage aligns with longstanding reporting standards in research and thesis writing.

This tense is particularly appropriate for the Methods and Results sections, because they document events tied to a specific temporal frame. As a result, past tense helps maintain narrative coherence and distinguishes procedural facts from broader theoretical assertions.

What tense should be used in the methodology section?

The methodology section should be written in past tense, because it describes actions already executed. Phrasing such as “Data were coded using qualitative content analysis” or “The model was tested across three sample groups” conforms to academic norms.

A past tense method example would be:

“Participants completed a baseline questionnaire, and the research team analyzed responses using non-parametric statistical tests.”

This approach ensures clear delineation between documented actions and interpretive commentary.

Why does the results section rely on past tense?

The results section uses past tense because it reports findings derived from completed procedures. Statements such as “The intervention increased completion rates” or “Group A scored higher than Group B” are typical. Even when results may remain relevant in the present, the act of analysis itself occurred at a fixed moment, which places the narrative in the past.

This convention is also recommended in major academic writing resources, including *University of Manchester Academic Phrasebank*, which emphasizes past tense for empirical outcomes.

How should present tense be used in academic writing?

Present tense is appropriate when referring to general truths, established knowledge, or the content of the paper itself. It is used in introductions, theoretical explanations, and parts of the discussion section. For example: “This study examines the relationship between motivation and study habits” or “The literature indicates significant variability in learner engagement.”

Present tense positions the argument within the ongoing body of scholarly knowledge and communicates that the claim remains valid or accepted.

When should the present perfect tense appear in research writing?

Present perfect appears when discussing prior research that continues to influence the present discourse. Phrases such as “Researchers have proposed multiple frameworks” signal continuity between earlier work and current inquiry.

This tense also indicates that scholarly debates remain active. It is particularly useful in literature reviews and background sections because it situates research within a larger academic trajectory.

Can future tense be used in a research paper?

Yes—future tense may be used sparingly. It is appropriate when outlining recommendations, identifying limitations, or discussing implications for future research. Examples include:

“Future studies will need to replicate these findings across larger populations.”
“Further research will examine longitudinal trends.”

Excessive reliance on future tense is discouraged, as it may introduce speculation rather than evidence-based claims.

How do tenses differ in thesis writing compared to shorter research papers?

Theses follow the same core tense conventions as research papers, but the longer format sometimes enables more variation. For example, a thesis may use present tense when describing its own structure (“Chapter 3 discusses…”) or present perfect when summarizing accumulated research.

Some departments maintain strict preferences—often detailed in institutional style guides—so reviewing recent departmental theses or consulting supervisory expectations is recommended.

Common errors include:

Using present tense to describe completed methods
(e.g., “We use ethnographic interviews” instead of “We used…”)
Switching tenses within a single paragraph without logical reason
This disrupts coherence and can obscure meaning.
Overusing present perfect in literature reviews
This can make scholarship seem undefined or too generalized.
Using future tense in methodological descriptions
Only use future tense for proposed or hypothetical research, not reported studies.

Such errors are frequently highlighted in academic writing centers, such as those at University of North Carolina Writing Center.

FAQs

When should I use past tense in a research paper?

Use past tense for reporting methods, describing results, and documenting any completed action associated with your study.

What tense should I use in the methodology?

The methodology must be written in past tense to accurately reflect completed procedures.

Can future tense appear in a research paper?

Yes, in sections discussing limitations or recommendations for future research.

Should the introduction be written in present or past tense?

The introduction is typically written in present tense for general statements and present perfect for summarizing ongoing scholarly discussions.

Are the tenses used for thesis writing the same as journal articles?

Yes, though theses may include additional present-tense references to their structure or aims.
