and Why It Matters in a Literature Review
One of the most common pieces of feedback postgraduate students receive on their literature reviews is that their writing is “too descriptive”. Often, this comment appears repeatedly, even after revisions.
What is usually missing is not effort or reading, but a clear understanding of the difference between summary and synthesis.
This distinction sits at the heart of postgraduate academic writing. Understanding it can transform how you read, organise, and write your literature review.
What summary looks like in a literature review
Summary focuses on individual sources. It answers the question:
What does this author say?
In summary-based writing, paragraphs often:
- centre on one author at a time
- describe the argument of a single text
- move from source to source without clear connection
For example:
Smith (2018) argues that…
Jones (2020) suggests that…
Ndlovu (2022) finds that…
This kind of writing shows that reading has taken place. However, it does not yet demonstrate how the literature connects, where debates exist, or how ideas relate to one another.
At undergraduate level, summary is often sufficient. At postgraduate level, it is not.
Why summary feels easier (and safer)
Many students rely on summary because it feels concrete. When you summarise, you are reporting what is already there. The task feels contained and verifiable.
Synthesis, by contrast, requires judgement. It asks you to decide:
- which ideas belong together
- which differences matter
- which patterns are worth highlighting
Without clear guidance, this can feel risky. Students may worry about “getting it wrong” or misrepresenting the literature, so they retreat to summary as a safer option.
This is not a lack of ability. It is a lack of explicit instruction.
What synthesis actually means
Synthesis focuses on relationships between sources, not individual texts.
Instead of asking “What does this author say?”, synthesis asks:
- How do scholars approach this issue?
- Where do they agree or disagree?
- What patterns or tensions emerge across studies?
In synthesis-based writing, paragraphs are organised around ideas, themes, or debates. Multiple sources appear within a single paragraph because they are contributing to the same analytical point.
For example:
Several scholars argue that postgraduate writing difficulties are linked to lack of explicit instruction (Smith, 2018; Jones, 2020). However, other studies emphasise institutional constraints rather than pedagogical gaps (Ndlovu, 2022).
Here, the structure is driven by the idea, not by the authors.
How synthesis makes your academic voice visible
Many students worry that they are not “allowed” to have a voice in a literature review. In reality, your voice is present in how you synthesise.
Your voice appears in:
- how you group sources
- which debates you foreground
- how you describe patterns and gaps
- how you transition between ideas
You are not inserting personal opinion. You are making analytical choices.
This is what examiners are looking for when they ask for “critical engagement”.
Why synthesis matters for examiners
Examiners read literature reviews to assess more than knowledge of sources. They are also looking for:
- conceptual understanding
- ability to organise complex material
- readiness for independent research
Summary-heavy writing can suggest surface-level engagement, even when a student has read extensively. Synthesis signals intellectual maturity and control over the field.
This is why feedback such as “too descriptive” often persists until synthesis improves.
How to begin moving from summary to synthesis
The shift from summary to synthesis does not happen automatically. It needs to be supported deliberately.
Helpful starting points include:
- identifying themes before writing
- tracking ideas across multiple sources
- asking relational questions while reading
- writing paragraphs around concepts rather than authors
Most importantly, synthesis becomes easier when you stop relying on memory alone and begin using tools that support thematic thinking.
A practical next step
If you find yourself summarising because you are unsure how to synthesise, structured support can help.
The Literature Review Foundations Bundle is designed to:
- explain the difference between summary and synthesis clearly, and
- support synthesis while you read, not only when you write
It combines conceptual guidance with a practical literature review log that helps you track ideas across sources and organise them thematically.

Final thought
Summary shows that you have read.
Synthesis shows that you understand.
Learning to synthesise is not about intelligence — it is about being taught how to think differently with the literature.
That skill can be learned.
