What this plugin does

Critical Thinking Tools is a science-backed Claude Code plugin from Cognitive Bias Lab that helps users reason more clearly about decisions, beliefs, plans, forecasts, and disagreements. It provides structured thinking workflows based on research in psychology, decision science, forecasting, intelligence analysis, and debiasing.

The plugin includes 12 practical tools: devil’s advocate review, pre-mortem analysis, outside-view forecasting, competing hypotheses, consider-the-opposite, steelmanning, Socratic questioning, base-rate audits, causal story dissection, calibration forecasting, decision journals, and groupthink red-team checks.

Each tool guides Claude to produce structured outputs with likely bias risks, evidence that would change the conclusion, next actions, and a short science note. The plugin is designed as a practical judgment aid, not a guarantee of unbiased thinking, and emphasizes uncertainty, evidence updates, and careful reasoning.
