Quick tips for rubric selection

Repertorization succeeds or fails at the point of rubric selection. Choose rubrics that are too broad and every remedy scores; choose too few and the picture is thin; count mechanically and the analysis points to the wrong remedy with great confidence. Six disciplines, drawn from Kent and refined by the errors that recur when an analysis fails to converge, turn rubric selection from guesswork into method.

The six tips at a glance

1. Choose characteristic rubrics, not common ones

The rubrics that decide a case are the characteristic ones — the strange, rare, and peculiar, and the marked generals — not the common symptoms shared by hundreds of remedies. A rubric like "Mind: anxiety" carries little discriminating power; a precise, peculiar rubric narrows the field meaningfully. Build the analysis around the symptoms that individualise this patient, and let the common symptoms confirm rather than drive the choice.

• Action: select rubrics for the characteristic symptoms first.
• Why: common rubrics do not distinguish between remedies.
• Well-suited for: analyses where too many remedies score highly.
• Trade-off: identifying what is truly characteristic takes judgement.

2. Size the rubric to the case

A rubric containing 400 remedies tells you almost nothing; a rubric of 15 to 100 remedies discriminates well. Where a large general rubric and a smaller, more specific sub-rubric both fit, prefer the specific one, because it carries more information. Watching rubric size as you build the analysis keeps any single over-broad rubric from flattening the result and drowning the characteristic symptoms in noise.

• Action: prefer specific sub-rubrics of moderate size over large general ones.
• Why: over-large rubrics add little discriminating power.
• Well-suited for: keeping the analysis from collapsing toward polychrests.
• Trade-off: the most specific rubric is sometimes too small to contain the right remedy.

3. Grade rubrics by their importance to the case

Not every selected rubric deserves equal weight. Most software lets you grade a rubric — commonly 0 to 4 — to reflect how central that symptom is to the case, so the analysis weights it accordingly. This mirrors the classical hierarchy of symptoms, where peculiars and marked generals outrank common particulars. Grade deliberately rather than leaving everything at default, or the analysis treats a trivial symptom as if it mattered as much as a decisive one.

• Action: grade each rubric by its importance to the case before analysing.
• Why: the hierarchy of symptoms means rubrics carry unequal weight.
• Well-suited for: analyses that feel skewed by minor symptoms.
• Trade-off: grading is a judgement call that two practitioners may make differently.

4. Use natural-language search to find the right rubric

The right rubric often exists under wording you would not guess. Typing a symptom as the patient said it — into a semantic repertory search — can surface rubrics that share no exact words with the query, reducing the classic failure of missing a rubric because you searched the wrong term. Keyword search remains available for exact matching when you already know the repertory wording, so the two modes complement each other.

• Action: search semantically when you are unsure of the repertory's exact wording.
• Why: the right rubric is frequently worded differently from the patient's phrase.
• Well-suited for: practitioners who miss rubrics by searching the wrong term.
• Trade-off: a close-meaning match is not always the correct rubric; review before adding.

5. Cross-check a rubric before you trust it

Rubric wording, placement, and remedy contents vary between repertories and editions, so a rubric that looks right may carry a different remedy set than you expect. Before relying on a rubric, open it and read its remedies and grades, and where it matters, check the same symptom in another repertory. This guards against importing one source's idiosyncrasy into your analysis as if it were settled fact.

• Action: open and read a rubric's remedies and grades before trusting it.
• Why: rubric contents differ by repertory and edition.
• Well-suited for: cases where the analysis hinges on one or two rubrics.
• Trade-off: cross-checking every rubric is slow; reserve it for the decisive ones.

6. Read the analysis, do not just count it

The remedy at the top of the count is a candidate, not a verdict. The classical method asks whether a remedy fits the whole picture — the characteristic symptoms, the mentals, the modalities — not merely whether it covers the most rubrics. Use the analysis grid to see which remedies cover the decisive rubrics, then read those remedies in the materia medica before prescribing. A high count built on common rubrics can point confidently to the wrong remedy.

• Action: confirm the top candidates against the materia medica and the case picture.
• Why: the remedy must match the totality, not just the rubric tally.
• Well-suited for: avoiding a confident prescription from a misleading count.
• Trade-off: reading candidates in the materia medica adds time to every case.

FAQ

How many rubrics should an analysis have?

There is no fixed number; the right count is however many characteristic symptoms the case offers, typically a handful of decisive rubrics rather than dozens. Padding the analysis with common rubrics weakens it. A few well-chosen, well-graded rubrics usually discriminate better than a long list of generic ones.

Does the software's top remedy decide the prescription?

No. The analysis ranks remedies by coverage of the selected rubrics, but the prescription follows the practitioner's judgement of fit against the whole case and the materia medica. The tally is a guide to where to look, not the decision itself, and treating it as the decision is a common source of failed prescriptions.

Can AI choose the rubrics for me?

It can suggest them. Notes-to-rubrics and live tools propose rubrics from what you record, each named and overridable, but the selection — accepting, rejecting, or switching a rubric — stays with you. The judgement about which symptoms are characteristic, and therefore which rubrics matter, is the clinical act the tools support rather than replace.

Verdict

Sound rubric selection is characteristic symptoms, right-sized rubrics, deliberate grading, meaning-based search, cross-checking, and reading the analysis rather than counting it. Master those six disciplines and the analysis stops misleading you.
