"Activate when: user says 'what would prove this wrong', 'how do we know if our strategy is working', 'what would change your mind', 'this claim feels unfalsifiable', or is designing a hypothesis/experiment/investment thesis that needs to be made testable.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Falsifiability ## Overview A meaningful empirical claim must specify what observations would refute it. Claims that resist all possible refutation are not science — they are unfalsifiable belief. Formalized by Karl Popper (1934): science progresses not by accumulating confirmations but by surviving rigorous attempts at falsification. More-specific claims are more falsifiable; ad-hoc modifications that explain away failures destroy a claim's scientific status. Composes with [`confirmation-bias`](../confirmation-bias/SKILL.md) (falsifiability is the structural counter), [`abductive-reasoning`](../abductive-reasoning/SKILL.md) (generates hypotheses; this skill tests them), [`bayesian-reasoning`](../bayesian-reasoning/SKILL.md), [`critical-thinking`](../critical-thinking/SKILL.md). ## When to Use - Designing OKRs, KPIs, or strategic goals; writing or evaluating investment theses - Designing experiments (A/B tests, product hypotheses, market entry) - Evaluating consultant/advisor recommendations or diagnosing vague leadership claims - Someone says "what would change your mind," "how would you know you're wrong," "Popper" …

How to install
mdr add deciqai/knowledge-skills/falsifiability@sha256:d505eac6775adc71The line at the top of this page pins the label git:20261025.cb4e537, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
