Chapter 3. Data and methods

3.1The primary texts

The primary texts are two. The first is Part II, Chapter IV of James Lind's A Treatise of the Scurvy (Edinburgh, 1753), printed pages 191 to 196, from the paragraph that begins with the date of the trial to the paragraph that sums up its result, together with Lind's footnote (g), a letter from a naval surgeon named Ives (Lind 1753). The only text of this chapter available to the study is the Internet Archive's machine reading of a Wellcome Library copy, kept uncorrected: the long s is mostly read as f, and words at line ends are often misread. The rules under which this article was written forbid quoting a text in that state, since a quotation copied from it would reproduce the machine's errors as Lind's words. Lind is therefore followed here in close paraphrase, in his own order, and no sentence of his is given in quotation marks. Every detail attributed to him below is in that chapter.

The second is Edward Jenner's An Inquiry into the Causes and Effects of the Variolae Vaccinae (London, 1798), first edition, in the proofread transcription of Project Gutenberg (Jenner 1798). The parts used are the dedication of 21 June 1798 and the opening argument, Case XVII and the paragraphs after it, Case XVIII, and the closing pages. Jenner is quoted at length and word for word, including his spelling ("head-ach") and his double hyphens. Omissions are marked with an ellipsis between two verbatim pieces.

3.2The platform records

Beside each text stands a record written by Skeptron, a studio of the RISCON family that publishes questions about the past drawn from public records. Each record gives a dated event, a short scenario, and five questions with Skeptron's answers: the date of the record, a concrete fact, the boundary of what can be judged, a calendar check, and the condition of a later comparison. The two records used here are titled, in the English translation, "Lind's Twelve-Seamen Scurvy Comparison Trial" (Skeptron's key HQ-HC2-LIND1747) and "Jenner's 1796 Vaccination Record and 1798 Report" (HQ-HC2-JENNER1796), both dated 2026-09-14. This article refers to them by the parent study's short labels, Lind's Twelve Sailors and Jenner's Inquiry, which are not Skeptron's titles.

These records are modern summaries written for the platform. They are not archival documents, and they are not eighteenth-century evidence of anything. Neither is a synthetic scene: both are public-record questions built on public sources that the records name (for Lind, two pages of the James Lind Library; for Jenner, the Gutenberg text and an article in the Journal of the Royal Society of Medicine). Skeptron writes in Korean. The records are quoted here in an English translation made once for the parent study, and the quotations are copied from that translation character for character. Where a record and a primary text differ, both are given.

Each record also carries sentences that recur, with names and dates changed, across Skeptron's history cases. They are Skeptron's method, not findings about these cases. One of them, which appears in both records in slightly different translated words, reads in the Lind record:

This article treats such sentences as the platform's house rules and does not read them as evidence of anything about 1747 or 1796. The fourth question of each record, a calendar check, says nothing about the event and is not used.

3.3The ledger

This article is drawn from a longer study, Before the Count, which reads twenty-three of Skeptron's medical and public-health cases closely and codes eighty-nine of its history cases on the same questions. The coding was done twice, independently, by one AI model run twice; each coding gave a value for each question, the words in the record that supported it, and a reason. A value counts as settled only when the two codings agree. The questions the study asked of every case were registered, with its hypotheses and predictions, before any case was coded. Among them: does the record show a public act on disease; was the act taken before its cause or its own effect was established; does the record name a gap in time between an event and its report; does it give a count, and how does it qualify it; does it name who bore the cost while the act waited; and does it name a later finding that would change how the act should be read.

The ledger's values for the two cases are given in the Appendix in the ledger's own terms. In the body of the article they appear only as plain sentences. The ledger is a reading of the records, not of Lind's and Jenner's texts; where the texts say more than the records, the article follows the texts.

3.4Reading for claims

The reading of each report follows the three-way sorting that Neustadt and May proposed for decision makers (Neustadt and May 1986), adapted to a document: what the trial as described could show, given its arms, its subjects, its duration and its measure; what the author marks as uncertain, by a hedge, a qualification or an open question; and what the author asserts beyond the trial without marking it. The third class is the measure of the article's question. It is reported sentence by sentence, not as a tally, and nothing in it is a judgment of the authors' competence or honesty.
