From a question to a finished set of materials, in six steps
This is how the evidence-rulings example was made. Each step shows what the AI did, what the author decided, and a link to prompts you can adapt. The steps work for any topic where you have a lot of documents and a short time to teach.
Start with a question worth teaching
We asked: where do trial-court evidence rulings get appealed, and where do they actually get reversed? A good teaching question is specific, answerable from public sources, and interesting to your audience.
Gather the material, and count what you found
We collected the relevant appellate opinions for one year (July 1, 2025 to June 30, 2026), one month at a time.
Break it down into a structure
Each opinion became one row in a table with the same columns: which rule was at issue, whether the court found error, whether the error mattered, and what happened.
Audit before you show anyone
Before building anything pretty, we asked a separate AI session to act as a skeptical auditor.
The audits confirmed the arithmetic, and they found real problems in the coding, three truncated rule texts and several overstated claims. See what went wrong below.
Show it, so people can explore instead of just read
The result became an interactive heat map: every opinion is one mark, grouped by rule. Hover for a preview, click for details and the official court document.
Design choices worth copying: one mark per item so nothing is hidden in an average; shapes and colors so it works without color vision; a plain table alternative; and links back to primary sources everywhere.
Package it for the room
The same data became a short discussion card, a poster, a field guide, a “how we know” sheet, and slide decks for 5, 10 or 15 minutes.
What went wrong, which is the most useful part
Two audits caught statements in our own materials that were stronger than the data supported. Here are the headline ones. If you take one habit from this site, take this: ask for the audit.
| The claim | What the data showed | The fix |
|---|---|---|
| “All eight reversals are published opinions.” | Seven are. One was an unpublished memorandum decision. | Say “seven of eight.” |
| “Reversals never exceeded about 11% in any month.” | March reached 16.7% (2 of 12). Months only hold 10 to 20 opinions each. | Report the real range, 0% to 16.7%, and note the small counts. |
| “A second, independent pass confirmed the results.” | The second pass used the same tools and model, so it shows consistency, not independence, and no second-pass data is published. | Call it a consistency check, not proof, and plan a read-through by a person. |
| “4.5% of rulings are reversed.” | It is 4.5% of the 176 opinions found, not the chance any trial ruling is reversed. Rulings never appealed aren’t counted. The interval (2.3% to 8.7%) is a Wilson score interval. | Say “share of coded opinions,” with the interval. |
| “Reversed in fewer than 1 in 20.” | That is a point estimate. 8 of 176 is about 1 in 22, and the upper end of the interval is 8.7%. | Say “8 of 176 opinions, about 1 in 22, with the interval.” |
| (Unstated) Every field was fully filled in. | 49 records had placeholder values in some fields because that quarter was coded in a lighter first pass. | Label those fields “not coded” and analyze only the 127 complete records. |
| “Every rule page is the official text.” | Three rules (402, 604 and 801(c)) had lost text when the pages were built. The second audit found it by comparing every rule with the official site. | Restore the text, say “as supplied,” and link the official page. |
| “Checked,” “verified,” “every figure on every page.” | The audit verified arithmetic, not coding. In a random sample of 12 criminal opinions, two outcome codes were wrong. | Say what was checked and what was not, and label the rest screening-grade. |
| Reporter citations printed as fact. | None of the N.E.3d citations has been checked against a primary source, and some strings are shared by different cases. | Label every citation “unverified” and lead with docket, date and the court’s link. |
Where AI helps, and where you must
AI is strong at
- Reading many long documents quickly, as a first pass
- Sorting them into categories you define
- Drafting handouts, slides, captions and speaker notes
- Building a visual or interactive page from a table
- Recomputing totals with code you can inspect, and flagging claims that don’t match the table
You must still
- Decide the question, audience and categories
- Verify anything that will be cited or relied on
- Read the records behind the headline numbers
- Keep confidential or personal information out of the tool
- Say plainly what is and isn’t verified
