Metric Gaslighting Detector

Q: How do I know the Metric Gaslighting Detector output is good?

The skill verifies itself against its own quality checks: Every 🔴 names the specific mechanism and what the conclusion becomes without it — "misleading" alone is not a finding; At least one metric is graded 🟢 or the audit admits the artifact gave nothing to clear — all-guilty audits read as motivated; The honest retelling uses only the numbers present — the detector doesn't smuggle in its own speculation; Questions are answerable from data the owner plausibly has, and none contain an accusation.

Find out how a dashboard, KPI report, or metrics slide is lying to you — before you repeat its story in a bigger room. Use when numbers feel too tidy, a narrative rests on one chart, or you inherited metrics you didn't define. Produces a deception audit: every metric graded for the eleven classic distortions (denominator games, survivorship, y-axis crimes, cherry-picked windows…), the story the data would tell under honest framing, and the three questions to ask the metric's owner.

What to give it

▸The metrics artifact — the dashboard description, KPI table, chart, or the numbers with their labels exactly as presented. Include axis ranges, time windows, and any annotations; the lie usually lives there.

▸The claim being made with it — (if any) — "churn is under control", "the launch worked". The audit tests the *claim-data* connection, not the data alone.

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓Every 🔴 names the specific mechanism and what the conclusion becomes without it — "misleading" alone is not a finding

✓At least one metric is graded 🟢 or the audit admits the artifact gave nothing to clear — all-guilty audits read as motivated

✓The honest retelling uses only the numbers present — the detector doesn't smuggle in its own speculation

✓Questions are answerable from data the owner plausibly has, and none contain an accusation

✓Distortion names from the list are used consistently so repeated audits build a shared vocabulary

⚠️ What it refuses to do

Do not accuse people of lying — the framing is "what belief does this arrangement create vs what the data supports"; most gaslighting dashboards are self-deception forwarded

Do not grade a metric 🔴 for a distortion that doesn't change the decision at hand — severity is about consequences, not purity

Do not demand data that doesn't exist as a gotcha — the three questions must be realistically answerable

Do not rewrite the numbers — the honest retelling reframes; it never adjusts figures

Do not skip auditing metrics that support conclusions you like — run the eleven on the favourable ones first
