Activate when: user says 'we keep finding evidence that supports our view,' 'the team is all aligned on this,' 'I've done the research and it checks out,' or a decision moves forward with only supporting evidence cited. Do NOT activate when: context is explicit advocacy (legal brief, pitch deck) where one-sided argument is the design; or stakes are too low to justify structured disconfirmation.

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
# Confirmation Bias ## Overview **Confirmation bias** is the systematic tendency to seek, interpret, remember, and weight evidence in ways that support existing beliefs — and to correspondingly miss disconfirming evidence. It is the most-replicated finding in cognitive psychology, documented across cultures, expertise levels, and IQ ranges. The canonical proof: Wason's 1960 "2-4-6 task" showed ~80% of subjects (including PhD scientists) confidently announced a wrong rule after testing only sequences they expected to confirm — never proposing a sequence designed to refute the hypothesis. Composes with [`critical-thinking`](../critical-thinking/SKILL.md), [`bayesian-reasoning`](../bayesian-reasoning/SKILL.md), [`abductive-reasoning`](../abductive-reasoning/SKILL.md), and [`metacognition`](../metacognition/SKILL.md). ## When to Use - A team is converging on a single answer too quickly - You feel confident about a claim and haven't looked for evidence against it - Research or due diligence keeps "validating" existing beliefs - Someone says "cherry-picking," "echo chamber," or "looking for what you want to see" …

How to install
mdr add deciqai/knowledge-skills/confirmation-bias@sha256:430f66f5c25ff07dThe 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.
