7 Synthesis
In this chapter, we will practice:
- describing a set of sources that are “in conversation” with one another
- comparing and contrasting two or more sources
- identifying themes in a set of sources and across a conversation
What do we mean by synthesis? Where analysis calls on us to break an artifact down into individual parts, synthesis requires us to make connections between those parts or—in most academic writing—among sources, topics, or events (just to name a few possibilities). A common type of synthesis in academic writing, for example, is a literature review in which the researcher-writer collects, compares, and shows connections or differences among different scholarly sources as well as gaps in the research. With academic writing foremost in mind, Lumen Learning defines synthesis as “analysis across sources,” adding that “what you write in reaction to the work of others should use synthesis to create new meaning or to show a deeper understanding of what you learned.” The idea is not just to summarize but to make connections. That feature is what makes synthesis so important: it’s critical thinking in action.
For example, in a movie review, you might first identify, summarize, and analyze key parts of the film, such as genre, plot, and specific techniques like suspense, background music, or humor. You might also find, summarize, and evaluate other critiques of the film. Synthesis relies on these skills, asking you to point out relationships between film elements, compare other critiques, note what’s missing or unexamined, then draw new, hopefully insightful conclusions of your own. Lumen Learning suggests, “… look for connections and patterns …[and] themes among your sources.” The idea is to connect ideas and show relationships from source to source. sources.” In other words, look for similarities, differences, and gaps. What did other critics or scholars say about a particular topic? On what points do they differ? Where do they agree? What have they missed?
In fact, we synthesize all the time but may not realize we’re gathering, comparing, and evaluating sources in this way. For example, imagine this scenario: You and a group of friends want to attend a movie together but cannot decide which one. Each of you makes a recommendation, summarizing key details about your choices (genre, good reviews, compelling plots, and so forth). Together, you and your friends compare the films, discuss each other’s assessments of the options available, and reach a conclusion: you’ll go see the sci-fi flick! That’s synthesis (or “analysis across sources”). In this case, your friends’ individual analyses are your sources; your discussion and conclusion is the synthesis.
Synthesizing Research
For a more academic project, imagine that you need to gather sources, annotate them, then report what connections, differences, gaps, and other relationships you found. That’s one approach to writing a literature review, a common academic genre that synthes
