After each observation, keep only hypotheses that still fit, then prefer the survivor with the fewest unsupported assumptions as the working explanation.\n\n## When to Use\n\n- A bug, incident, or anomaly has more than one plausible cause.\n- You can observe code, logs, diffs, traces, tests, configs, or data now.\n- You must localize the faulty file, function, branch, config, or invariant before fixing.\n- Competing explanations fit the same surface facts and you need a discriminating check.\n\n## When NOT to Use\n\n- Cause is already obvious from a single stack, failing test, or recent diff — fix directly.\n- Only one plausible hypothesis exists — test it; do not invent rivals for ritual.\n- No observation is possible yet — obtain access first; do not speculate a localization.\n- Multi-week experiments, product A/B tests, or policy trials — this skill is for agent-now checks.\n- Fault is already localized and you need systemic root/prevention depth — use five-whys-plus.\n- Selective \"only these objects/times\" defects better suited to IS/IS-NOT comparison — use Kepner-Tregoe.\n- Representation (doc/dashboard) may be stale versus reality — verify territory with map-territory first, then resume hypotheses.\n\n## Procedure\n\n1. **State the symptom precisely.** Capture failing behavior, scope, timing, environment, and constraints. Separate observation from interpretation.\n2. **Enumerate 2–5 competing hypotheses.** Name specific files, functions, configs, input conditions, or invariants. Reject vague buckets (\"backend issue\"). If no serious alternative remains after a deliberate check, exit this differential and test or fix the sole evidenced cause directly; never fabricate a rival to continue the procedure.\n3. **Name falsifiers and cheap observations before looking.** For each hypothesis: what result drops it, and what read/grep/diff/log/test check can you run now. Prefer observations available immediately over deploys, canaries, or long waits.\n4. **Rank observations by discrimination × cheapness.** Run the cheapest check that best separates the top contenders. Do not deep-dive the favorite first if a cheap cross-check would kill alternatives.\n5. **Update after each observation.** Drop falsified hypotheses. Among survivors that still fit all evidence, prefer the one with the fewest independent unsupported assumptions (extra components, rare timing, external dependencies). Parsimony ranks survivors after fit; it never rescues a leaner hypothesis that evidence already contradicts. Escalate complexity only when simpler survivors are ruled out.\n6. **Localize and stop.** When one hypothesis has direct supporting evidence and key alternatives are ruled out, name the file/function/config to change and the evidence that localizes it. Stop analyzing once localization is direct.\n\n## Output\n\n```text\nSymptom: <specific failing behavior, scope, timing>\nHypotheses:\n  H1: <specific cause> | Why plausible | Observation | Falsified if\n  H2: ...\n  H3: ...\nTest order: <cheapest discriminating checks>\nResults: <what each observation showed>\nSurvivors: <remaining Hs; least-assumptive working pick among fit>\nLocalized fault: <file/function/config + supporting evidence>\nRuled out: <Hs dropped and why>\n```\n\n## Verification\n\n- Falsify the differential conclusion if you continued with fewer than two serious hypotheses, if no pre-stated falsifier existed, if a cheaper discriminating check was skipped, or if a \"simpler\" story was kept after evidence contradicted it.\n- Stop when the fault is directly localized and alternatives that matter are ruled out; do not continue theorizing.\n- Over-application guard: do not narrate observe→question without competing causes; do not treat fewest assumptions as proof; do not run this skill when a single obvious cause is already evidenced.\n","tagline":"When a symptom has several plausible causes, rank falsifiable hypotheses and run the cheapest discriminating observation first; prefer least-assumptive survivors only after evidence fit.","category":"automation","tags":["agent-skill"],"author":"tjboudreaux","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github fast track","sourceDetail":"tjboudreaux/cc-thinking-skills","creatorName":"tjboudreaux","creatorUrl":"https://github.com/tjboudreaux","sourceUrl":"https://github.com/tjboudreaux/cc-thinking-skills/tree/main/skills/thinking-scientific-method","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/tjboudreaux-thinking-scientific-method#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
