Evidence Grading

Category: Science & Research  ·  Sub-category: science-misc  ·  Last updated:
Grade the evidence behind a claim before betting on it — the hierarchy for business evidence (experiments > usage data > surveys > interviews > anecdotes > opinion), the fit-for-decision test, and the mixed-evidence verdicts that real questions produce. Use when asked how strong is our evidence for this, grade what we know before the decision, is this enough to bet on, or we have three anecdotes and a survey — now what. Produces the evidence inventory with grades, the sufficiency verdict against the decision's stakes, and the cheapest-upgrade path.

"We have evidence" covers everything from a randomized experiment to the CEO's seatmate on a flight — and decisions made on ungraded evidence inherit the confusion. The grading discipline: inventory what actually supports the claim, place each item on the business-evidence hierarchy (what it is, not how confident it feels), test the graded weight against the decision's stakes (a reversible pilot needs less than a one-way rebrand — [decision-journal](../decision-journal/SKILL.md) logic), and when evidence falls short, name the cheapest upgrade — because the answer to weak evidence is usually a…

What this skill does

Evidence Grading is a community-contributed Claude Code skill in the science-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/evidence-grading/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when asked how strong is our evidence for this, grade what we know before the decision, is this enough to bet on, or we have three anecdotes and a survey — now what. Produces the evidence inventory with grades, the sufficiency verdict against the decision's stakes, and the cheapest-upgrade path.
