Synthesis, Sources and Tone

Synthesis means pulling ideas from several sources into one argument of your own. You pick the most useful details from each source and connect them, so the sources talk to each other instead of being summarized one at a time.

A source gives you information, but not every source is equally trustworthy. Before you lean on one, check who wrote it, what they know, where and when it was published, and how well it supports its own claims.

A position is what someone thinks about an issue; a perspective is where they're coming from, such as their job, background or interests. A scientist and a business owner might back the same policy for very different reasons.

Every source has some bias and some limits, like a small sample, an old date or a one-sided view. Strong arguments admit those limits and explain how they affect the evidence, and a source that ignores other views is usually more biased.

As you read more sources, you may find evidence that doesn't fit your first claim. Instead of ignoring it, you adjust your thesis and your line of reasoning so the argument still holds up.

Tone is the writer's attitude toward the subject, and you work it out mostly from word choice. Words with positive or negative connotations, like "thrifty" versus "stingy", show how the writer feels.

Writers sometimes change tone partway through a text, for example from mocking to serious. A shift like this often signals that the writer is qualifying, sharpening or rethinking their view, so ask why it happens where it does.
