Interview Synthesis Skill
Interview piles get "synthesized" two bad ways: the highlight reel (the quotes that confirmed what the team hoped) and the mush ("users want simplicity" — twelve hours of conversation flattened into a poster). Honest synthesis is mechanical before it's interpretive: code the notes (what did each person actually say, tagged), count the themes (a theme is something multiple people said — with the number attached), preserve the divergences (the two dissenters are data, not noise), and size every claim to the sample — twelve interviews support "we repeatedly heard," never "users want."
What This Skill Produces
- The coded pass — each interview's statements tagged to emerging codes, traceable back to the speaker
- The theme table — themes with counts (7/12 raised unprompted; 3 more agreed when asked — the prompted/unprompted split matters)
- The divergence report — who disagreed with each theme and why; the outliers examined, not deleted
- The claims, sample-sized — findings phrased at what N interviews can carry, with the quotes that illustrate honestly
Required Inputs
Ask for these if not provided:
- The notes/transcripts — the actual material; synthesis of summaries synthesizes the summarizer's biases
- The questions the interviews served — what the study was trying to learn; themes get organized against them (plus the "unexpected" bucket, often the best one)
- The sample's shape — who these people are, how selected (12 enthusiastic volunteers ≠ 12 representative users — the selection shapes what claims are legal)
- What the team already believes — stated up front as hypotheses; the synthesis marks confirms/contradicts explicitly (the contradicts are the expensive-to-lose ones)
Framework: The Synthesis Rules
- Code before theming: pass one is mechanical — each substantive statement tagged (needs-integration, pricing-confusion, workaround-X) with speaker attribution. Themes emerge from tag frequencies, not from memory — memory promotes the vivid, and vividness isn't prevalence.
- Count, and split prompted from unprompted: every theme carries its number ("8/12"), and unprompted mentions outweigh prompted agreements — "seven raised pricing before we asked" is a finding; "everyone agreed pricing matters when asked" is politeness. The counts keep the highlight reel honest.
- Divergence is data: the two who disagreed get examined — different segment? Different workflow? Their why often reveals the theme's boundary condition ("the theme holds for teams over ten; both dissenters were solo"). Deleting outliers manufactures consensus; bounding themes with them manufactures insight.
- Quotes illustrate counted themes — never substitute for them: each theme gets 1–2 verbatim quotes chosen for representativeness (the middle of the distribution, not the spiciest take), attributed at the agreed anonymity level. A vivid quote for a 2/12 theme is cherry-picking with production values.
- Size claims to the sample and selection: twelve interviews earn "a recurring pattern among [who we talked to]" — not "users want," not percentages ("58% of users" from n=12 is numerical cosplay). The confidence line states sample, selection, and what would harden the finding ("survey to size it" — the survey-design-basics handoff).

1---2name: interview-synthesis3description: Turn a pile of interview notes into findings that survive scrutiny — the code-then-theme pass, the counting discipline (how many actually said it), the quote selection that illustrates instead of cherry-picks, and the confidence lines a small sample earns. Use when asked synthesize these user/customer/exit interviews, what did we actually learn from the calls, turn 12 transcripts into insights, or are these themes real. Produces the coded themes with counts, the divergences preserved, the illustrative quotes, and the claims sized to the sample.4---5

Honest synthesis is mechanical before it's interpretive: code the notes (what did each person actually say, tagged), count the themes (a theme is something *multiple* people said — with the number attached), preserve the divergences (the two dissenters are data, not noise), and size every claim to the sample — twelve interviews support "we repeatedly heard," never "users want."

271. **Code before theming:** pass one is mechanical — each substantive statement tagged (needs-integration, pricing-confusion, workaround-X) with speaker attribution. Themes emerge from tag frequencies, not from memory — memory promotes the vivid, and vividness isn't prevalence.
282. **Count, and split prompted from unprompted:** every theme carries its number ("8/12"), and *unprompted mentions outweigh prompted agreements* — "seven raised pricing before we asked" is a finding; "everyone agreed pricing matters when asked" is politeness. The counts keep the highlight reel honest.
293. **Divergence is data:** the two who disagreed get examined — different segment? Different workflow? Their *why* often reveals the theme's boundary condition ("the theme holds for teams over ten; both dissenters were solo"). Deleting outliers manufactures consensus; bounding themes with them manufactures insight.
304. **Quotes illustrate counted themes — never substitute for them:** each theme gets 1–2 verbatim quotes chosen for *representativeness* (the middle of the distribution, not the spiciest take), attributed at the agreed anonymity level.

50## Quality Checks
51
52- [ ] Every theme traces to coded statements with counts
53- [ ] Unprompted and prompted mentions are distinguished
54- [ ] Divergences are examined for boundaries, not discarded
55- [ ] Quotes are representative of counted themes, not highlights
56- [ ] No claim exceeds what n and selection legally support
57
58## Anti-Patterns
59
60- [ ] Do not synthesize from memory — the vivid interview colonizes the findings; coding is the antidote
61- [ ] Do not present percentages from small samples — counts, plainly
62- [ ] Do not delete the dissenters — they're the theme's boundary survey team
63- [ ] Do not quote the spiciest take as the finding — representative or labeled as an outlier
64- [ ] Do not let confirmation win silently — the contradicted hypotheses are the synthesis's most valuable line
