Synthesis

Synthesis is the skill of combining information from multiple sources to create new understanding. Unlike summary (which restates what sources say), synthesis creates connections between sources, identifies patterns of agreement and disagreement, and develops original insights from the combination of perspectives.

Summary vs. Synthesis

Summary Synthesis
Reports what each source says separately Shows how sources relate to each other
"Source A says X. Source B says Y." "While Source A emphasizes X, Source B's focus on Y reveals a tension between..."
Neutral retelling Analytical combination that creates new insight
Sources remain separate Sources are woven together around themes or questions

Types of Synthesis Relationships

When synthesizing sources, look for these relationship patterns:

Agreement/Confirmation

Sources support the same conclusion from different angles or evidence.

Signal phrases: "Similarly," "Likewise," "In agreement with," "Supporting this view," "Confirming this finding"

Example: "Both Martinez and Chen conclude that early childhood education improves long-term outcomes, though Martinez emphasizes cognitive benefits while Chen focuses on social development."

Disagreement/Contradiction

Sources reach opposing conclusions or contradict each other.

Signal phrases: "In contrast," "However," "Conversely," "Disputes this view," "Challenges the assumption"

Example: "While Thompson argues that standardized testing improves accountability, Garcia contends that such testing narrows curriculum and harms student engagement."

Qualification/Nuance

One source adds conditions, exceptions, or nuance to another's claims.

Signal phrases: "Although," "While acknowledging," "With the caveat that," "Except when," "Under certain conditions"

Example: "Johnson's enthusiasm for technology integration is tempered by Lee's research showing that benefits depend heavily on teacher training and implementation quality."

Extension/Development

One source builds on, expands, or applies another's ideas.

Signal phrases: "Building on," "Extending this analysis," "Taking this further," "Applying this framework"

Example: "Park's economic analysis extends Williams's sociological observations, showing how the community patterns Williams identified translate into measurable financial outcomes."

Gap/Silence

One source addresses what another overlooks or ignores.

Signal phrases: "Notably absent from," "What X overlooks," "Filling this gap," "Addressing what Y ignores"

Example: "While Smith thoroughly analyzes environmental costs, his work notably ignores the economic impacts on rural communities that Davis's research brings into focus."

The Synthesis Process

  1. Read and annotate: Identify each source's main claim, evidence, and perspective
  2. Find connections: Look for agreements, disagreements, and patterns across sources
  3. Identify themes: Group related ideas that appear across multiple sources
  4. Develop your insight: What new understanding emerges from combining these perspectives?
  5. Organize around themes: Structure your synthesis by theme, not by source

Writing Synthesis Thesis Statements

A strong synthesis thesis doesn't just list sources—it articulates the insight that emerges from combining them.

Weak (Summary-Based) Thesis

"Three authors discuss the effects of social media on teenagers."

Strong (Synthesis) Thesis

"Although researchers agree that social media affects adolescent development, their conflicting emphases on psychological harm versus social connection suggest that the medium's impact depends largely on how teenagers use it—a nuance with significant implications for parenting and policy."

Organizing Synthesis Writing

Structure synthesis by theme or idea, not by source:

  • Wrong: Paragraph 1 about Source A, Paragraph 2 about Source B, Paragraph 3 about Source C
  • Right: Paragraph 1 on Theme 1 (drawing from multiple sources), Paragraph 2 on Theme 2 (drawing from multiple sources), etc.

đź’ˇ Examples

Example 1: Identifying Synthesis Relationships

Source A: "Exercise improves cardiovascular health and reduces the risk of heart disease."

Source B: "Physical activity enhances cognitive function and memory retention."

Source C: "However, excessive exercise can lead to injury and burnout, particularly among competitive athletes."

Relationships:

  • Sources A and B are in agreement—both support exercise benefits, though emphasizing different systems (cardiovascular vs. cognitive)
  • Source C provides qualification—it doesn't contradict A and B but adds an important limitation ("excessive" exercise, "competitive athletes")

Synthesis insight: Research consistently supports exercise's health benefits across multiple body systems, though these benefits have limits that depend on intensity and context.

Example 2: Converting Summary to Synthesis

Summary version: "Smith argues that remote work increases productivity. Jones found that remote workers report higher job satisfaction. Williams claims that remote work can lead to isolation and communication problems."

Synthesis version: "The remote work debate reveals a tension between individual and organizational outcomes. While both Smith and Jones document benefits for individual workers—increased productivity and satisfaction respectively—Williams's research on isolation and communication challenges suggests that these individual gains may come at the cost of team cohesion. This pattern indicates that successful remote work policies must balance personal flexibility with strategies to maintain collective connection."

Why it's better: The synthesis version identifies the underlying tension (individual vs. organizational), shows how sources relate, and develops an original insight about policy implications.

Example 3: Writing a Synthesis Paragraph

Topic: Urban green spaces and public health

Sources:

  • Chen: Parks reduce stress and anxiety in city residents
  • Martinez: Access to green space correlates with physical activity levels
  • Thompson: Green space benefits are unequally distributed across income levels

Synthesis paragraph:

"Research consistently demonstrates that urban green spaces promote public health through both psychological and physical pathways. Chen's studies show that parks reduce stress and anxiety, while Martinez's findings reveal that access to green space increases physical activity—together suggesting that parks function as preventive healthcare infrastructure. However, Thompson's work on environmental equity complicates this optimistic picture, demonstrating that green space benefits are concentrated in wealthier neighborhoods. This disparity means that the populations most in need of parks' health benefits—low-income communities with higher rates of stress and chronic disease—often have the least access to them. Thus, expanding urban green spaces without addressing distribution may actually worsen health inequalities."

Example 4: SAT/ACT-Style Synthesis Question

Question: Based on the paired passages, how would the author of Passage 2 most likely respond to the claim in Passage 1 that "technology in education universally improves student outcomes"?

Passage 1 claim: Technology universally improves outcomes

Passage 2 position: Technology's impact depends on implementation quality and teacher training

Analysis: Passage 2 would likely qualify Passage 1's claim. The author wouldn't completely disagree (technology can help) but would challenge the word "universally," arguing that outcomes depend on how technology is implemented. The relationship is qualification/nuance, not outright disagreement.

Best answer type: "The author of Passage 2 would likely argue that Passage 1 overstates technology's benefits by ignoring the conditions necessary for those benefits to materialize."

Example 5: Identifying Themes Across Sources

Task: Three articles discuss climate change policy. Identify common themes.

  • Article 1: Focuses on carbon pricing and market-based solutions
  • Article 2: Emphasizes technological innovation and renewable energy
  • Article 3: Advocates for individual behavior change and consumption reduction

Emerging themes:

  1. Level of action: Government/market (Article 1) vs. industry/technology (Article 2) vs. individual (Article 3)
  2. Theory of change: Economic incentives vs. innovation vs. cultural shift
  3. Implicit assumptions: Each article assumes its approach is sufficient, but together they suggest comprehensive solutions may require all three levels

Synthesis insight: The diversity of proposed climate solutions reflects disagreement not just about tactics but about where responsibility lies—a tension between systemic and individual approaches that effective policy must somehow bridge.

✏️ Practice

Apply your synthesis skills to these exercises.

Problem 1: Identify the relationship: Source A says "Social media helps people stay connected with distant friends and family." Source B says "Social media use correlates with increased feelings of loneliness and depression." What type of synthesis relationship is this?

Problem 2: Revise this summary into synthesis: "Johnson says homework helps students learn. Williams says homework causes stress. Park says parents should help with homework."

Problem 3: Which thesis is a synthesis thesis? A) "Three researchers have studied sleep and health." B) "While researchers agree that sleep affects health, their conflicting recommendations about optimal duration suggest that sleep needs may be more individual than previously assumed."

Problem 4: Source A argues minimum wage increases help workers. Source B argues they hurt small businesses. Source C argues effects depend on local cost of living. What is Source C's relationship to A and B?

Problem 5: What's wrong with this organization? "Paragraph 1: Smith's research on exercise. Paragraph 2: Jones's research on exercise. Paragraph 3: Williams's research on exercise."

Problem 6: Write a synthesis thesis for these sources: Source A says college is essential for career success. Source B says vocational training provides better job prospects in some fields. Source C says the value of college depends on major and institution.

Problem 7: Identify the synthesis relationship: "Building on Martinez's observation that reading improves vocabulary, Chen's longitudinal study demonstrates that these vocabulary gains translate into measurable improvements in workplace communication."

Problem 8: What theme connects these sources? A: Cities should invest in public transit. B: Walkable neighborhoods reduce car dependence. C: Bike-sharing programs decrease traffic congestion.

Problem 9: Convert to synthesis: "First, I will discuss Article 1. Then I will discuss Article 2. Finally, I will discuss Article 3."

Problem 10: Source A focuses on economic benefits of immigration. Source B focuses on cultural enrichment from immigration. What does neither source address that might be important?

Click to reveal answers
  1. Disagreement/Contradiction — The sources reach opposing conclusions about social media's effects on connection vs. loneliness.
  2. Sample synthesis: "The homework debate reveals competing values in education. While Johnson emphasizes academic learning benefits, Williams's research on stress suggests these benefits may come at a psychological cost. Park's focus on parental involvement adds another dimension, raising questions about equity for students whose parents cannot help—a factor neither Johnson nor Williams addresses."
  3. B — Option A merely announces a topic; B articulates an insight that emerges from comparing sources.
  4. Qualification/Nuance — Source C doesn't fully agree with A or B but suggests both may be right under different conditions.
  5. The organization is by source rather than by theme. This produces summary, not synthesis. Better: organize by themes that appear across multiple sources.
  6. Sample thesis: "Although the 'college for all' narrative dominates public discourse, research reveals that post-secondary value is highly context-dependent—varying by field, institution, and individual circumstances—suggesting that effective career guidance requires nuanced assessment rather than universal prescriptions."
  7. Extension/Development — Chen builds on Martinez's finding by showing its real-world application.
  8. Theme: Alternative transportation and urban design to reduce car dependence. All three sources address different strategies toward the same goal.
  9. Sample revision: "These three articles approach [topic] from different angles but converge on [theme]. While Article 1 emphasizes X and Article 2 focuses on Y, Article 3's attention to Z reveals [insight]. Together, they suggest [synthesized conclusion]."
  10. Possible gaps: Challenges of immigration (integration difficulties, labor market effects on existing workers, strain on services). Both sources present only positive aspects, creating an incomplete picture that ignores legitimate concerns.

âś… Check Your Understanding

Question 1: What is the key difference between summary and synthesis?

Show answer

Summary reports what each source says separately, keeping sources isolated. Synthesis shows how sources relate to each other—identifying agreements, disagreements, and patterns—to develop new insights that emerge from the combination. Summary is descriptive; synthesis is analytical and creates new understanding.

Question 2: Why should synthesis writing be organized by theme rather than by source?

Show answer

Organizing by source produces summary (Source A says X, Source B says Y), keeping sources separate. Organizing by theme forces you to put sources in conversation—multiple sources appear within each paragraph, connected by their relationship to the theme. This structure naturally produces synthesis because it requires showing how sources relate to each other and to your analytical point.

Question 3: How do you identify synthesis relationships when reading multiple sources?

Show answer

Ask these questions as you read: Do sources agree or disagree? Does one source qualify or add nuance to another? Does one extend or build on another's ideas? Does one address what another ignores? Look for patterns: similar conclusions from different evidence (agreement), opposing conclusions (disagreement), conditional statements (qualification), or building on previous work (extension).

Question 4: What makes a thesis statement a "synthesis thesis" rather than a "summary thesis"?

Show answer

A synthesis thesis articulates an insight that emerges from comparing sources, not just what sources say. It identifies patterns (agreements, tensions, gaps) and makes a claim about their significance. A summary thesis merely announces the topic or lists what sources discuss. Synthesis thesis: "Although experts agree on X, their disagreement about Y reveals..." Summary thesis: "Three experts discuss X."
