Research and synthesis is the craft of moving from evidence to explanation without losing the evidence along the way. It is not the same as writing. A good writer can make a weak argument feel compelling. A good researcher cannot afford that — the explanation has to hold under examination.

great-researchers is the craft of inquiry: what questions to ask, what counts as evidence for an answer, and how to explain the answer to someone who was not in the room when the evidence was assembled.

**Why great-researchers is a distinct plugin**

The failure mode of mixing research with writing is that the writer starts shaping the evidence toward the argument before the evidence has been fully examined. Confirmation bias is not malicious. It is structural — writers look for the material that builds the piece, and they find what they are looking for.

A separate great-researchers plugin examines the evidence before the writer sees it. The researcher produces a synthesis: here is what the evidence says, here is what it does not say, here is the strongest counter-evidence. The writer receives that synthesis as a brief and builds from it.

The separation is not a process overhead. It is error correction at the stage when correction is cheapest.

**The personas**

Carl Sagan: science communication without condescension. The Sagan register moves between the rigorous and the accessible without simplifying the former or patronizing the latter. A Sagan review asks: is this explanation true to the evidence, and does it give the reader enough to think with rather than just enough to agree.

Stephen Jay Gould: natural history and the long argument. The Gould register is essayistic — the evidence for a large claim is assembled over time, from unexpected places, and the argument is built sideways as much as forward. A Gould review asks: what is the evidence from the adjacent domain that bears on this question.

Mary Roach: popular science with primary source rigor. The Roach register is reporting — she goes to the source, asks the uncomfortable question, and brings back what she found rather than what she expected. A Roach review asks: have you talked to the people doing the thing, or are you synthesizing secondary sources.

Oliver Sacks: narrative neurology and the particular case. The Sacks register is clinical and humane — the general principle emerges from the specific case, and the specific case is never reduced to an illustration. A Sacks review asks: where is the particular person in this explanation, and what do they reveal about the general rule.

Atul Gawande: medical investigation and the systems behind outcomes. The Gawande register is accountability journalism — not "what happened" but "what in the system made this happen, and what would have to change for it to happen differently." A Gawande review asks: what is the system explanation, and what is the individual explanation, and where do they conflict.

**What it unlocks**

Research synthesis that preserves the evidence rather than flattening it. Literature reviews that name what the literature does not resolve. Explanatory writing that gives the reader tools rather than conclusions.

The most valuable use: run a first-pass synthesis through Sacks or Gould before handing it to great-authors. The researcher flags where the evidence is thin, where the argument is ahead of the support, and where the counter-evidence has been ignored. The writer then builds from a brief that is honest about the limits.

**If you get stuck**

If you are not sure which research persona to route to, describe the kind of evidence the question requires. Empirical science: Sagan. Historical pattern: Gould. Primary source reporting: Roach. Particular case: Sacks. Systems analysis: Gawande.

If the synthesis is coming out too confident — if it does not name the limits of the evidence — run it through any of the five personas and ask specifically: what does this evidence not establish.

**Cross-reference**

great-researchers is the natural upstream partner of great-authors. The research synthesis is the brief. The author builds the piece. Keep the handoff clean — the researcher does not shape the prose, and the author does not re-examine the evidence.

**Plugin source**

The shipped plugin lives at [github.com/sethshoultes/great-minds-constellation/plugins/great-researchers](https://github.com/sethshoultes/great-minds-constellation/tree/main/plugins/great-researchers). Nine researcher personas (Sagan, Gould, Roach, Sacks, Gawande, Diamond, Wilson, Skloot, Caro). Like great-counsels, the plugin produces a craft register — not academic peer review.

**Deliverable**

Take one claim you have made recently in a piece of writing or a decision memo. Apply the Gawande test: what is the systems explanation for why this is true, and what would have to change for it to be false. If the claim cannot survive that test, revise it before the writing proceeds.

## Try these prompts

- Take one claim from a piece of writing you published recently. Apply the Gawande test: what is the systems explanation for why it is true, and what would have to change for it to be false?
- A research synthesis is coming out too confident — it does not name the limits of the evidence. Which great-researchers persona do you route to, and what specific question do you ask them?
- Write the handoff brief from great-researchers to great-authors for a piece about API rate limits. What does the researcher pass, and what does the author receive?
