Belief Revision
A structured framework for AI agents to revise a prior verdict, classification, hypothesis, or analysis when new evidence emerges — calibrated against both under-correction (anchoring on the prior) and over-correction (anchoring on novelty or social pressure). Use whenever the task involves updating a previously reached conclusion in light of new information, reconsidering a verdict after primary sources are fetched, deciding whether a contested claim should change classification, integrating a late-breaking piece of evidence into an existing investigation or peer review, or any request to "update this", "revise this", "rethink this in light of X", "does this new evidence change anything", "should I change my mind". Pair with whichever analytical skill produced the prior — this skill takes that output and produces a calibrated revision in its format.

Update a prior verdict when new evidence emerges — calibrated, traceable, and protected against both under-correction (anchoring on the prior) and over-correction (anchoring on novelty or social pressure).
What this skill does
Belief Revision is a community-contributed Claude Code skill in the research-methods sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/belief-revision/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use whenever the task involves updating a previously reached conclusion in light of new information, reconsidering a verdict after primary sources are fetched, deciding whether a contested claim should change classification, integrating a late-breaking piece of evidence into an existing investigation or peer review, or any request to "update this", "revise this", "rethink this in light of X", "does this new evidence change anything", "should I change my mind". Pair with whichever analytical skill produced the prior — this skill takes that output and produces a calibrated revision in its format.
Who uses this skill
