Synthesis begins when a reader stops treating two texts as separate summaries and starts asking what becomes visible when the texts are placed in relation to each other. The task is to identify common ground, disagreement, different assumptions, complementary evidence and differences in scope.
Summary is not synthesis
Summary asks what Text A says and what Text B says. Synthesis asks how the two positions connect. Two writers may agree on the problem but disagree on its cause. They may support the same conclusion using different evidence. One may make a broad claim that the other qualifies.
The comparison grid
- Central claim: what does each writer want accepted?
- Evidence: what kind of support does each use?
- Assumptions: what does each take for granted?
- Scope: how broad is each claim?
- Qualification: where does each recognise limits?
- Perspective: what priorities shape each account?
Worked example
Text A argues that remote work improves productivity because employees lose less commuting time and gain more control over concentration. Text B accepts that remote work can improve individual concentration but argues that collaboration becomes harder when teams lack deliberate communication systems.
A weak response gives two summaries. A synthesis states that both texts recognise productivity benefits, but Text B narrows Text A’s claim by showing that individual efficiency does not automatically produce effective team coordination.
Compare like with like
Do not compare an example from one text with the thesis of another as though they perform the same job. Compare claim with claim, evidence with evidence and qualification with qualification. Functional comparison produces cleaner reasoning.
Agreement can hide different reasoning
Two writers may both support public transport investment while one emphasises environmental effects and the other emphasises access to employment. The conclusion overlaps, but the argumentative foundations differ. A strong synthesis preserves that difference.
Use relationship language
Useful verbs include supports, qualifies, extends, challenges, complicates, narrows, reinforces and contradicts. These verbs force the writer to name the relationship rather than merely place two summaries beside each other.
Synthesis audit
- Have I identified each text’s actual claim?
- Am I comparing ideas that perform equivalent jobs?
- Have I named the relationship between them?
- Have I preserved important differences in scope or certainty?
- Does my final sentence tell the reader what we understand from reading both texts together?
